The entrance chamber still smelled of blood and crystalline residue. Reiji stood near the stone archway, shoulders tense, watching Ryu emerge from the twisted respawn portal with a stumble. The boy's armor was marked with scorch patterns—fresh scars from the Guardian's lightning phase. He'd respawned somewhere else in the dungeon, probably near the second-floor junction.

  Thirty minutes before dark.

  "Everyone accounted for?" Taiga asked, hands on his sword hilt. The berserker's right arm bore bandages—neat ones, applied by Hana—but his eyes were sharp, assessing. Not beaten. Not even close.

  Reiji nodded. "Ryu's back. Hana recovered fully. Tomoe's been analyzing the Guardian's attack patterns."

  Hana stood to the side, arms crossed, her healer's robes still stained with combat powder. Her eyes tracked Reiji with something unreadable. She'd died too, after all. Crushed against the wall when the Guardian had surged forward and the party's defense collapsed. The respawn notification had burned in his vision: "You are dead. Your consciousness has been restored."

  Tomoe sat cross-legged on a stone bench, fingers dancing across her status screen, pulling up combat logs and damage calculations. Her fox ears twitched with concentration. "The Guardian uses a sequence," she said without looking up. "Seven-hit combination, then a charge attack, then it recovers. During recovery—the arms lower, the core exposure window opens. That's when we deal maximum damage."

  "We were disorganized before," Ryu said, flexing his fingers. New sword, courtesy of the starter armory. "Trying to all attack at once. We scattered its threat attention."

  "So we coordinate." Taiga crossed his arms. "Hana stays protected. Ryu and I handle frontline rotation. Tomoe strikes when the opening presents itself. Reiji keeps everyone at acceptable health. Standard strategy."

  It wasn't wrong. It was textbook party dynamics. But Reiji's hand moved to his skill menu without thinking, fingers hovering over "Sacrifice." The skill had burned through his health bar when he'd used it as an act of desperation—absorbing the Guardian's final attack meant for Hana. It had cost him his life, but it had also revealed something: the skill worked. It transferred damage. It created options where none existed.

  This time, he wouldn't use it as a last resort.

  "I'm using Sacrifice strategically," Reiji said quietly. "Not when we're desperate. When I choose to. The Guardian targets whoever has the lowest health bar. If I use Sacrifice on Taiga deliberately, we control the damage distribution instead of reacting to it."

  Taiga's eyes narrowed. "You're going to take damage on purpose."

  "Yes."

  "While keeping everyone else alive."

  "Yes."

  The berserker grunted, a sound that might have been approval or skepticism—Reiji had learned not to ask. "Riskier. But it's flexible. I'll take it."

  Hana stepped forward. "Reiji, you can't maintain that balance for the full duration. Your stamina recovery—"

  "Will be enough if we end this quickly." Reiji cut her off, not unkindly. "Fifteen minutes, maximum. We hit hard during recovery windows. No hesitation. No mercy."

  Ryu nodded, rolling his shoulders. The second-floor respawn point had given him time to think, at least. That much was clear from his posture—calmer than before, more centered. The first death had broken something open in him. Made survival feel real instead of abstract.

  Reiji watched the boy, reading the micro-expressions. Ryu's lips were pressed into a thin line. His breathing was controlled but shallow—the breathing of someone who had already decided to go back in. The respawn chamber's isolation had done something to him. Forced him to choose: accept the death as final and quit, or recommit to the Guardian's chamber. He'd chosen the latter.

  "The timing is critical," Reiji continued, pulling up the combat log one more time. The Guardian's attack sequence was burned into his memory now—not just the mechanics, but the rhythm. The way each strike flowed into the next. The microsecond delays where the system calculated impact and recovery. The moments where the creature was fully committed to a pattern and couldn't deviate.

  He'd used those moments to keep people alive. He needed to do it again.

  "Taiga, when the Guardian charges, don't try to absorb full force. Angle your sword like this—" Reiji held up his hands, demonstrating the deflection angle he'd used in the first attempt, the attempt that had killed him. "Redirect, don't resist. Resisting will break your guard and waste stamina. Redirect eats the momentum instead."

  Taiga studied the angle, nodding. The berserker's understanding was intuitive rather than calculated. Reiji had learned to appreciate that. Taiga didn't need all the numbers and sequences. He just needed the principle, and his body would translate that into movement.

  "And Ryu," Reiji said, turning to the boy, "you're going to catch strikes three and four. Watch for the rhythm. The Guardian accelerates. If you treat it like a musical beat, you'll predict the timing better than if you watch the attack itself."

  Ryu's eyes widened slightly. It was an odd comparison, but Reiji had spent five years studying this fight—studying not just the mechanical patterns but the way they translated to human perception. Treating it as rhythm instead of individual attacks was how he'd survived the longest.

  "Let's move," Taiga said.

  The walk to the Guardian's chamber felt different this time. The descent through the dungeon corridor, the way the stone gradually shifted from carved walls to natural crystal growth, the temperature dropping as they approached the creature's domain—all of it registered in Reiji's awareness with hyperclarity. His body was moving toward something that had already killed him once. His mind was processing this with a strange detachment. He'd already been through this. Not this specific version, not this specific attempt, but the general shape of it. Death and respawn. Fight and survive. The cycle that every player in this System went through.

  Except he'd already survived it once before. Five years of it. And that should have made him fearless.

  It didn't.

  Hana walked behind him, and he could sense her attention on his back. She didn't speak. Neither did the others. They'd already committed to the strategy. Now it was execution.

  The Guardian's chamber looked exactly as it had before. Same vaulted ceiling, same obsidian floor, same crystalline walls that reflected their movement back at them in fractured images. The beast itself rested in the center—a towering construct of fused stone and something luminous that hurt to look at directly. Core exposed, waiting.

  Reiji's health bar was full. Everyone's health bar was full.

  "Formation," he called out as they spread across the chamber floor.

  The Guardian's core flared.

  The fight began with the same telegraph as before—a slow contraction of the creature's upper body, shoulders drawing back, arms coiling. Reiji had memorized the timing over the course of their first attempt. Three seconds until the seven-hit combination began. Three seconds to position.

  His heart was beating too fast. The memory of the last death was still fresh—the moment when his health bar vanished and the world went white. He pushed the memory aside. This time was different. This time he had a plan.

  "Hana, two steps back. Now."

  She moved without argument. The Guardian exploded forward, all grinding stone and that terrible luminous shriek. Its first strike aimed at the space Hana had occupied a heartbeat before. The blast of displaced air hit Reiji's face as the creature's limb passed—hot, electric, carrying the scent of ozone and something older. Something crystalline and wrong.

  The second strike came down at Taiga, who met it with his sword raised high, absorbing the blow with braced legs. The impact made a sound like a bell cracking—high-pitched, resonant, the kind of sound that traveled through bone rather than just ears. Taiga slid backward six feet across the polished floor, his boots squealing against the stone.

  Ryu was already moving, stepping into the space the Guardian had created, sword extended to catch the third and fourth strikes. Deflecting rather than blocking, letting the creature's momentum carry it forward and past him. The boy's movements were economical, sharp. Everything Reiji had suggested about rhythm must have registered because Ryu was reading the attacks like a musical sequence, predicting and positioning without wasting energy on surprise.

  The fifth strike came in at chest height. Ryu twisted, letting it slide past his armor. The sixth strike aimed at his legs. He jumped, and the Guardian's limb carved the space where his thighs had been a moment before.

  Tomoe was moving through the chaos like water. She rolled left when the seventh strike began its trajectory toward her. Right when the Guardian's second arm tracked her movement. Her dagger was already raised, waiting for the moment when the creature committed fully to an attack vector and couldn't defend itself against a counter.

  Reiji held his position near the center of the chamber, health bar dropping incrementally as passive damage from the fight's proximity ticked away. His job was to monitor, to calculate, to decide when to intervene.

  The seventh strike came down at him with the weight of a falling tower. He could have run. Should have, by any standard tactical logic. Instead, he threw his sword up—not to block, but to trigger his skill. His Ironbound defense activated, and Reiji's body was suddenly wrapped in reinforced layers, additional health bars stacked on top of his base pool. The Guardian's limb crashed into the augmentation, and the barrier shattered on contact. The blow connected anyway, and Reiji's primary health bar dropped by thirty percent.

  The impact sent him backward four feet. His boots skidded on the stone. Pain was a secondary concern—the System filtered physical sensation into something manageable, something he could process alongside tactical information.

  "Sacrifice," Reiji commanded, throwing his hand toward Taiga.

  The world shifted sideways.

  Taiga suddenly bore a shimmering overlay, and Reiji's own health bar dropped another twenty percent as the skill transferred his defensive augmentation to the berserker. The transfer was instantaneous, but Reiji's awareness of it wasn't—he could feel the connection snap tight, the power flowing from his body into Taiga's, the momentary vulnerability as he released his own protections.

  This tale has been unlawfully lifted from Royal Road; report any instances of this story if found elsewhere.

  It was controlled damage. Planned. Strategic. Not the desperate last act of someone with no other options.

  The Guardian contracted again, returning to recovery position. Its core glowed brighter as it gathered energy for the charge attack. Reiji's stamina bar flickered—currently at seventy percent, regenerating slowly. He'd need to be careful about when he deployed Sacrifice again. There was a ratio to maintain: skill cost versus natural regeneration. He'd calculated it during their walk down the corridor. He could use Sacrifice approximately four more times before his stamina dipped into dangerous territory.

  Tomoe exploded forward, her dagger raised high. She found the crystalline joint where the Guardian's upper and lower structures met—a seam in the construction, a place where the creature's builders had joined different sections. The blade bit deep, and the creature shrieked. That horrible grinding-glass sound that made Reiji's teeth ache and sent vibrations through the chamber.

  His status log flickered: -20% Guardian Health.

  Ryu was already positioning for the charge attack. "Shield formation!" he called out, and Taiga moved to interpose himself between the Guardian and Hana. The berserker's body became a wall, sword raised high to catch the incoming impact.

  The charge came—a thundering rush of stone and luminescence. The Guardian's mass accelerated across the chamber floor. Taiga stood firm, accepting the impact with his sword angled to deflect rather than resist. The creature's momentum carried it to the side, and it crashed into the crystalline wall with enough force to crack the surface.

  Taiga's health bar dropped by forty percent. The shimmering overlay from Sacrifice remained active, absorbing additional impact that would have shattered the berserker's defense entirely.

  "Healing," Hana whispered, and green light bloomed across the chamber. The magic felt warm to Reiji even from where he stood—a gentle pulse of restoration that washed over Taiga. The berserker's health surged back to eighty percent. The light touched Reiji as secondary effect, recovering ten percent of his own health. Not enough to be tactical, but it helped.

  Reiji's own health floated at fifty percent. Acceptable. Strategic. The delicate balance was holding.

  The seven-hit combination came again. Ryu was faster this time, his understanding of the rhythm deepening with each rotation. He caught three of the seven blows on his raised sword, letting the kinetic energy distribute through his arms and shoulders. Tomoe slipped between the Guardian's limbs with the fluidity of practice, striking at joints, at the seams where the monster's construction was weakest. Each hit cost it five percent health.

  The math became simple then: five percent per rotation, approximately seven rotations to zero. They were tracking ahead of schedule.

  One minute and thirty seconds since the fight had begun.

  Three rotations of the same pattern. Reiji coordinated his Sacrifice uses with precision—shifting the damage profile, preventing any single party member from dipping into critical range. He deployed Sacrifice on Ryu after the third rotation. On himself once, absorbing a stray hit that would have disrupted his healing focus. On Taiga again when the berserker's health dropped to sixty percent.

  His own health bar became a delicate instrument: never above sixty percent, never below twenty-five. The razor's edge. The place where heroes died or where they became something more.

  The Guardian's health was dropping visibly now. Its core had developed fissures in the crystalline structure—thin cracks that leaked luminous fluid onto the chamber floor. The creature was wounded. It was bleeding energy.

  Fourth rotation. The Guardian's health dropped to fifty percent. Its movement became jerkier, less fluid. The mechanical precision that had governed its attacks started to falter. Strikes were coming a split second slower. Recovery positions were lasting a moment longer.

  Weakness.

  Taiga pressed forward, sensing it. The berserker's strikes came harder, more aggressive. He was reading the opponent now, not just reacting to it. Ryu matched his pace, complementing rather than competing. The two of them formed a wall of steel and determination, pushing the Guardian back toward the chamber's far wall.

  The creature was being pressured. And pressure was the environment where it made mistakes.

  Sixth rotation. Thirty percent health remaining.

  Reiji felt the fatigue in his status bar then—his skill recovery was slowing. Sacrifice required stamina investment, and stamina naturally regenerated at a base rate. He'd crossed a threshold. The back-and-forth of using and recovering was becoming tight. He could manage, but barely. The stamina bar showed twenty-five percent. Two more Sacrifice deployments, and he'd be on fumes.

  The Guardian sensed his weakening, perhaps. Its next combination came faster, strikes overlapping, the seven distinct hits becoming more of a flowing sequence with barely any gaps. Ryu dropped to one knee when the fourth strike caught him across the shoulder—the deflection failed, and the Guardian's limb connected directly with the boy's armor. The impact cracked metal.

  Hana threw emergency healing at him instantly, and his health surged back from thirty percent to seventy. But the resource cost was visible. Her mana bar was dropping noticeably. Seven percent of her pool remaining. She was at the edge of exhaustion. Once her mana hit zero, she couldn't cast anymore. And without healing, the party would die within seconds.

  They had minutes, maybe less. This had to end now.

  "One more cycle," Reiji said, and his voice sounded steady even though everything inside him was screaming. Screaming about how close they were to failure. How thin the margin had become. "We finish this now."

  The Guardian contracted for recovery. Tomoe was already moving, her dagger raised, and she drove it straight down into the creature's core with both hands behind the blade. The dagger sank to the hilt, and the entire construct trembled. The fissures on the core expanded, spreading like cracks through ice. Branches of fractures multiplied across the crystalline surface.

  The luminescence that had powered the creature began to sputter. Flicker. Dim.

  Taiga closed the distance and drove his sword straight through the core's midsection. The impact shattered the construct from the inside. The Guardian didn't die so much as it broke—a fundamental shattering of whatever coherence held it together. The creature exploded into crystalline dust, no death throes, no final attack. Just a sudden, complete dissolution.

  The dust hung in the air for a moment, suspended in the disturbed air of the chamber. Then it fell like snow, covering the floor in a glittering carpet of what used to be the obstacle they'd come here to overcome.

  Silence.

  Fifteen minutes and seven seconds since the fight had begun. They'd beaten their target time.

  No one was dead.

  Reiji's knees buckled. He caught himself against a chamber wall, breathing hard. His lungs burned with each inhalation. The air in the chamber tasted like ozone and broken crystal—particles of the Guardian still suspended in the atmosphere, settling slowly onto every surface.

  His health bar was at eighteen percent. A single strong attack would end him. His stamina was completely depleted—showing zero, which meant he'd need several minutes to recover any meaningful amount. The System had pushed him to the absolute edge of viability.

  Hana was in similar shape, her mana bar flickering with empty reserves. She'd given everything to keep them alive during those final rotations. If Reiji had asked her for one more heal, she would have cast it, and then she would have collapsed from mana exhaustion.

  But no one was dead.

  The notification came without fanfare, appearing in the center of Reiji's vision in plain white text:

  TUTORIAL COMPLETION [successful]. +500 XP. Advanced Equipment Reward [pending]. Skill Enhancement Package [pending]. Full System Access Granted.

  Taiga let out a genuine laugh—a sound of pure relief, the kind of sound that comes from someone who'd stared at the possibility of death and chosen to fight anyway. He was checking his equipment screen, probably already looking for upgrades. The berserker moved with the loose posture of someone whose tension had finally released.

  Ryu slumped onto the stone floor, sword across his lap, just breathing. His breathing was shallow and rapid. His eyes had the glazed quality of someone processing survival. The boy had dropped to one knee during the fight, had taken a hit that cracked his armor, and had gotten back up anyway. He'd learned something about his own limits today. Something important.

  Hana moved to Reiji, placing a steady hand on his shoulder. The contact was warm. Real. Her fingers were trembling slightly—mana exhaustion causing minor muscle spasms.

  "You're still alive," she said. It wasn't a question.

  "Still alive," Reiji confirmed. The words felt strange in his mouth. Redundant. Of course he was still alive. He was standing. He was breathing. The alternative would have been darkness and respawn.

  Tomoe was staring at something on her status screen, her fox ears folded back slightly. Her expression was a mixture of wonder and confusion—the look of someone whose understanding of something fundamental had just expanded beyond its previous scope.

  "The System interface is different," she said slowly. "All our permissions just changed. Full access means—" She looked up, her eyes meeting Reiji's. "We can see everything now. The entire skill system, all the mechanics, no more locked information."

  This was the moment. The party had completed the tutorial. The training wheels were off. Full System access meant understanding, meant power, meant the ability to make informed decisions instead of operating on incomplete information.

  It also meant he could finally see what the System truly was.

  Reiji opened his full status screen. The notification had promised Advanced Equipment, Skill Enhancement, Full System Access. He saw the equipment rewards waiting in a floating menu—better armor that looked like it would actually fit his frame properly, a stronger sword, consumables labeled with unfamiliar names. He saw the skill enhancement options laid out in a branching tree structure that was far more complex than anything he'd studied in his five years of preparation.

  And then he saw his skill list.

  The familiar names were all there—Sacrifice, Ironbound Defense, Restoration, Sacred Barrier. Every skill he'd memorized from the original timeline, every skill he'd built his entire strategy around. But every single one carried a marker in red text that made his breath catch:

  DEPRECATED: Version 1.0 Legacy Module detected

  Below that marker, in smaller text that seemed to grow larger the more he stared at it:

  WARNING: Skills are from a previous system iteration. Continued use is not recommended. Full compatibility cannot be guaranteed.

  The words didn't compute at first. His mind tried to fit them into existing frameworks and failed. He read the message again. And again.

  The System wasn't the same. The skills weren't the same. The entire framework had changed since five years into the future—since the version he'd memorized, since the knowledge that had been burned into his consciousness through five years of study and practice and failed attempts.

  He'd memorized everything. All the optimal skill paths. All the strategies that led to victory and survival. All the calculations about stamina recovery, damage scaling, cooldown management. All of it had been built on the assumption that the System version he'd studied would be the System version he faced.

  And now the System was telling him that version was deprecated.

  That version was obsolete.

  That version couldn't be guaranteed to work.

  "Reiji?" Hana's hand tightened on his shoulder. "What's wrong?"

  He didn't answer immediately. He was still processing the red text. The phrasing was corporate, clinical, the kind of language you'd encounter in a software notice about version upgrades. Not the kind of language a LitRPG System usually employed. The System usually spoke in dramatic terms, in epic declarations, in language that made players feel like heroes.

  This notice made him feel like he was holding outdated documentation.

  He turned the screen so she could see it. Her eyes widened as she read the red text. Her fingers on his shoulder went cold.

  Behind them, Taiga stopped mid-celebration. His attention snapped to the chamber's corner where Reiji stood. The berserker's expression shifted from relief to something darker. Something concerned.

  "The system changed," Reiji said quietly. The words came out hollow. "Everything I remembered. It's all marked as legacy. Deprecated."

  Ryu stood up slowly, his eyes moving between Reiji and his own status screen. The boy's earlier confidence drained from his posture, replaced by something like vertigo.

  "What does deprecated mean?" Ryu asked.

  The question hung in the air. It was such a simple question. Such a straightforward one. Reiji took a breath and answered as clearly as he could.

  "It means," he said, watching the red text pulse with what felt like malicious emphasis, "that I've been operating on information that might not apply anymore. All the skills I remember from five years in the future—none of them work the way I thought they would."

  Tomoe was already diving deeper into her status screen, her fingers flying across visible options. Her expression shifted from curiosity to genuine concern. The fox-eared girl's ears rotated backward, a sign of distress.

  "There are new skill categories," she said, more to herself than to the group. "Classes I don't recognize. The entire progression structure is different from what was described in the starter materials."

  Taiga walked over to join them, his expression hardening. The berserker had learned early in his life to accept information and adapt. But this information was fundamentally destabilizing.

  "Different how?" he asked.

  "Different like," Reiji said slowly, reading through the available skill options for a healer-type class, watching unfamiliar names and mechanics scroll past his vision, "I don't know what any of this means. All my preparation. All the strategies I've spent five years planning. All of it might be based on a System version that doesn't exist anymore."

  He closed his eyes and opened them. The red text was still there. Still glowing. Still marking every single thing he'd learned, every breakthrough he'd fought for, as obsolete.

  Outside the chamber, somewhere in the depths of the dungeon, the System was waiting. It was waiting with new rules. With new mechanics. With new versions of skills whose names he recognized but whose functions had changed.

  And Reiji had no idea what to do next.
