The seventy-two hours passed in a controlled blur of violence and instruction.

  Jonah drove them hard. Dawn drills focusing on footwork until their legs shook. Goblin hunts structured around specific tactical scenarios. Ambush response, fighting retreat, coordinated strikes. Evening sessions dedicated to System mechanics, explaining stat allocation, skill synergy, the mathematics of survival.

  They thought he was being cruel. He was being merciful.

  The tutorial zone offered controlled difficulty, enemies that could be predicted and managed. The real world wouldn't be so kind.

  By hour sixty, Martinez could maintain a defensive formation with John and Sarah rotating coverage seamlessly. Rebecca had progressed from reluctant healer to someone who understood triage priorities under fire. David's shield work showed genuine competence. Liam's blade sense had climbed to Advanced rank. The kid was a monster of natural talent, exactly as Jonah remembered.

  All of this was only possible within the system tutorial.

  Before the System's arrival, all of this would have taken a decade to fully grasp; without the system tutorial, it would take years.

  By hour seventy, they'd cleared three goblin camps and a minor dungeon Jonah led them to—the kind of optional content most groups avoided because risk outweighed reward for normal climbers.

  They emerged with better equipment, real combat experience, and skill ranks that would've taken weeks to develop through cautious progression.

  The System notification appeared for all of them simultaneously as the timer hit zero.

  [Tutorial Complete]

  [Final Evaluation: Exceptional Performance]

  [Bonus Rewards Calculated]

  [Prepare for Integration into Primary Zone]

  Light swallowed the world. That familiar sensation of reality dissolving, reassembling according to System parameters. Jonah's stomach lurched despite knowing it was coming.

  Then they were through.

  The spawn point materialized around them—a clearing in what had been a city park, recognizable by the twisted remains of playground equipment and a cracked basketball court. The sky overhead showed Earth's normal blue instead of the tutorial's violet-grey, but everything else had changed.

  Buildings in the distance showed corruption: vines that moved wrong, stone that had fused with organic matter, windows that reflected light at impossible angles. The System's integration of Earth into the Tower framework, transforming a mundane world into a climbable level.

  People clustered throughout the park in groups of varying sizes. Tutorial survivors, dumped back into the primary zone with whatever they'd managed to claim. Most looked shell-shocked, clutching basic weapons with white knuckles.

  Jonah's team looked different. They stood ready, weapons held with competence, eyes scanning for threats instead of staring at the corrupted landscape.

  Good.

  "Equipment check," Jonah ordered. "Make sure everything transferred correctly."

  They complied automatically now. Three days of following his instructions had built reflexive obedience to tactical commands.

  Jonah checked his own loadout. Short sword from the ruins cache, properly balanced steel that would serve until he could upgrade. The light leather armor he'd pulled from the dungeon, minimal protection but better than nothing. His mana core hummed in his chest, small but responsive.

  Still weak. Still pathetically underpowered compared to what he'd lost.

  But growing.

  Martinez pointed east. "Jonah. What's that?"

  A shimmer in the air, roughly three hundred meters away. Portal energy, distinctive even at this distance. The kind of signature that meant a cache or dungeon entrance.

  Or something more valuable.

  Jonah's pulse quickened. He knew that shimmer. Knew exactly what it protected.

  "Our next objective," he said. "Sarah, Liam. Scout ahead. Fifty meters, report back if you see other groups moving that direction."

  They moved without question. The others maintained defensive positions automatically, watching different quadrants.

  Jonah pulled up his System interface, checking the local area information. Time since integration: forty-three minutes. The tutorial had lasted seventy-two hours, but time dilation meant only the first wave had been through. More groups would be appearing throughout the day as their tutorials completed.

  Which gave him a limited window.

  "Clear," Sarah reported, jogging back with Liam. "Some groups near the buildings, but nobody moving this direction yet."

  "Double time. Stay tight." Jonah said.

  They crossed the distance fast, weapons ready, formation maintained. The shimmer resolved into a proper barrier as they approached, translucent energy surrounding a partially collapsed building—City Hall, based on the architectural style and the eagle statue lying broken near the entrance.

  Jonah had found this place on day four of his first life. By then, three other groups had already looted the accessible areas and he'd only claimed scraps, missing the real treasure completely.

  Not this time.

  "Rebecca, John—watch our backs. Everyone else with me."

  The barrier didn't stop them. Tutorial completion granted automatic access to primary zone resources. They passed through the shimmer with only mild resistance, like walking through a soap bubble.

  Inside, the building showed System corruption in full force. Walls merged with crystalline growths, floors warped at angles that hurt to perceive directly. But the main hall remained mostly intact, and more importantly, mostly unexplored based on the dust patterns.

  "What are we looking for?" David asked.

  "Everything useful. Weapons, armor, consumables. There's a weapons cache in the east wing—Martinez, take Sarah and clear it. Liam, you're with me. David, check the west offices for supplies." Jonah said.

  They split up. Jonah led Liam toward the collapsed section at the building's rear. Rubble blocked the hallway, but there was a gap, barely large enough to squeeze through.

  "In there?" Liam's voice carried skepticism.

  "In there."

  They crawled through. The space beyond opened into what had been a maintenance area, now transformed by System integration into something else entirely. Metallic vines covered the walls, glowing faintly with ambient mana. Strange fungi grew in corners, pulsing with bioluminescence.

  And there, on a pedestal that had definitely not existed in normal reality, sat a wooden chest.

  "Holy shit," Liam breathed.

  "Don't touch it yet." Jonah scanned the room for traps. The System loved tests, but this cache came from an older source, remnants from previous climbers, so different rules applied.

  If you discover this tale on Amazon, be aware that it has been stolen. Please report the violation.

  No visible triggers. No suspicious floor plates or energy patterns.

  He approached carefully anyway, hand ready to yank Liam back if something activated.

  Nothing happened.

  The chest opened with a simple latch. Inside: two daggers that hummed with enhancement magic, a set of bracers that would boost physical defense, and three talismans—paper-thin constructs covered in runic script.

  "Explosion talismans," Jonah explained, holding one up to the light. "Channel mana into the activation point, then throw them at your target. They detonate with about the force of a dozen hand grenades."

  "That's—how do you know that?"

  "Because I've used them before." Truth, from a future that hadn't happened yet. "Take the daggers. They'll serve you better than that basic sword for now."

  Those daggers were the best pieces of equipment that came out of this area.

  Liam accepted the weapons with reverence. Jonah pocketed the talismans and bracers. Good equipment, valuable resources, but not what he'd actually come for.

  "This way," he said, moving to the room's far corner.

  The fungi grew thicker here, forming almost a curtain across the wall. Jonah pushed through without hesitation. Behind them, hidden from casual inspection, a narrow staircase descended into darkness.

  "There's a basement?" Liam asked.

  "There's what I came for."

  The stairs went down two levels, ending in a chamber that the System had transformed into something close to a natural cave. The walls showed stone instead of concrete, as if the building's foundation had been replaced wholesale during integration.

  And there, sitting in a small alcove, untouched, was a leather-bound manual.

  Jonah's hands shook as he picked it up. The title was written in flowing script that shifted languages as he focused on it—Ancient Cultivation Methods: Foundations of Mana Circulation.

  The same manual that had accelerated his development in his first life. The cornerstone of every mana technique he'd built upon. He'd found it during week three then, tucked away in this same location but after others had ransacked the more obvious treasures.

  Now it was his from the start.

  "Is that a skill book?" Liam peered at the manual.

  "Better." Jonah opened it carefully, scanning the first pages to confirm authenticity. Perfect. Exactly as he remembered. "It's a cultivation manual: techniques for developing mana pathways, building capacity, and improving circulation efficiency."

  "But I'm a Swordsman. I don't use mana."

  "Everyone uses mana. Your class just channels it differently." Jonah closed the book, held it with both hands like the treasure it was. "System integration floods us with ambient mana, but without proper pathways, ninety percent bleeds away unused. This manual teaches you how to capture and utilize that energy."

  "For magic?"

  "For enhancement. Swordsmen channel mana into their bodies, their weapons, their techniques. And eventually they can summon Blade Auras and Sharp Arcs of intent. You think that Blade Sense skill is purely physical?" Jonah shook his head. "It's your body naturally routing small amounts of mana into your nervous system, improving reaction time and weapon awareness. This manual will teach you to do it deliberately, efficiently."

  Liam's eyes widened with understanding.

  "And mages?"

  "Same principles, different application. Mages develop external channels for spell manifestation. Warriors develop internal channels for physical enhancement. But the foundation is identical: efficient mana circulation through properly constructed pathways."

  They climbed back up to the main level. The others had gathered in the hall, arms loaded with supplies. Martinez had found a proper spear, military-grade with System enhancement humming in the blade. Sarah carried a bow and quiver of arrows that glowed faintly—probably minor tracking enchantments. David had scored a shield that actually fit him properly, along with a cache of preserved rations.

  "Good haul?" Jonah asked.

  "Better than I expected," Martinez confirmed. "You knew all this was here?"

  "I knew enough." Jonah held up the manual. "This is the real prize. Everyone's going to study it, learn the techniques. It'll take weeks to fully internalize, but even basic application will triple your effective power."

  "You're giving it to all of us?" Rebecca's surprise was evident.

  "Knowledge multiplies when shared; equipment gets divided." Jonah moved toward the exit. "Besides, we're a team. I need you all as strong as possible."

  They emerged from the building into afternoon light. More groups had appeared in the park—the second and third waves of tutorial completions. Maybe five hundred people total now, clustering in tribal groups, eyeing each other with suspicion.

  Jonah felt it in the air.

  The fear and paranoia that each one carried was palpable. How could he blame them after they witnessed hundreds die with each tutorial?

  Leaders with tense expectations argued with their counterparts.

  Strong parties created dark doctrine on living and the rest of the people here.

  Everything that was wrong with humanity would be purged in a grand event, one that lasted three years of great bloodshed, limiting their potential as a race against all of the other races.

  The First Human War was already gestating.

  Either he prevented it, or he got out of the way of the biggest and most dangerous actors.

  Jonah led his team to a relatively isolated corner, away from the main clusters. Time to establish proper foundation work before chaos consumed everything.

  "Everyone sit," he ordered. "We're doing basic circulation exercises."

  They complied. Jonah opened the manual to the introductory sections, the foundations he'd memorized so thoroughly he could recite them in his sleep.

  "Mana pathways exist in potential until you actively develop them. Imaginary lines that you can draw on your body," he began. "Think of them like muscles. Present in everyone, but weak until trained. The System integration flooded your bodies with ambient mana when you got your classes. Most of it dispersed because you lack the channels to retain it."

  He demonstrated the first exercise, a simple breathing pattern synchronized with conscious attention to the mana core in his chest. "Feel the warmth here." Jonah tapped his sternum. "That's your core. Every breath draws ambient mana from the environment. Most people exhale it immediately."

  "We're supposed to hold our breath?" David asked.

  "No. You're supposed to route the mana through initial pathways instead of letting it dissipate." Jonah traced lines on his own arm. "Primary channel from core to dominant hand. Secondary channel to legs. Tertiary through your head for mental enhancement."

  He guided them through it step by step. The manual's techniques were elegant in their simplicity, ancient methods refined across thousands of years and multiple species. Humanity's brief exposure to System mechanics meant they lacked tradition and proper instruction.

  This manual provided both.

  "It feels... warm?" Rebecca's voice carried uncertainty.

  "That's correct. The warmth is mana moving through fresh pathways. It'll feel uncomfortable at first, like stretching cold muscles or exercising for the first time in months. Push through it." Jonah monitored their attempts, correcting posture and breathing rhythm. "Liam, you're forcing it. Mana responds to intent, not effort. Relax."

  The kid adjusted, and Jonah saw the moment it clicked.

  Liam's eyes widened fractionally as proper circulation began.

  "There. That's the foundation. Fifteen minutes of practice daily will solidify the basic pathways. A month of dedicated work and you'll have functional circulation that enhances everything you do."

  "And you?" Martinez asked. "How long did it take you?"

  Jonah closed the manual. "Less time than it should have. But I had advantages."

  Understatement. He'd had forty-nine years of experience, muscle memory from a body that had pushed circulation techniques to their absolute limits, and knowledge of exactly which shortcuts worked versus which led to dead ends.

  They practiced for an hour: basic circulation and simple pathway development. Foundations mattered more than flash growth; Jonah had learned that lesson too late in his first life.

  The sun tracked toward the horizon. More people appeared in the park as additional tutorials completed. The crowd swelled toward a thousand, maybe more, with groups consolidating and leaders emerging. Territorial claims were being staked through body language and positioning.

  Jonah watched it all with clinical detachment. The patterns matched his memories: clusters forming around charismatic figures, stronger fighters attracting followers, the natural hierarchy of post-apocalyptic organization.

  He was cataloging faces when the commotion started.

  East side of the park, near where the old fountain had been. Raised voices, the kind that preceded violence. People shouting, others gathering to watch.

  Jonah stood immediately. His body moved before conscious thought processed the implications.

  He recognized one of those voices.

  Marcus Swell. Eighteen years old, college freshman, utterly unremarkable in almost every way. In Jonah's first life, Marcus had died on this exact day, murdered by another survivor over a territorial dispute that spiraled into something uglier.

  His death had become a rallying point. The first killing between humans post-integration. The spark that ignited deeper divisions that created the factional warfare consuming humanity's early climb.

  The First Human War had started with Marcus Swell bleeding out in a city park while people chose sides instead of intervening.

  At least in their bubble.

  Jonah was already moving before the first punch landed. He could stop their bubble from turning to a blood bath, but he had no access to the rest of humanity.

  "Stay here," he barked at his team. "Do not follow unless I signal."

  He crossed the distance at a controlled run, not so fast it looked like aggression, but fast enough to matter. The crowd had formed a ring around the confrontation. Two groups facing off, maybe fifteen people total. On one side, Marcus and three others, college kids based on their clothes. On the other, a larger group led by a man Jonah recognized.

  Derek Stone. No relation to Liam, despite the shared surname. Mid-thirties, former military, the kind of personality that confused brutality with leadership.

  In Jonah's first life, Derek had led one of the early factions. He had preached strength through dominance, survival of the fittest, all the toxic philosophy that justified atrocity. He'd died eventually on Level 8, killed by someone he'd abused once too often.

  But not before he'd left a trail of bodies and broken people behind him.

  Right now, Derek was shouting at Marcus while his people formed an intimidating wall.

  "—don't care about your excuses, kid. You were in our section when the integration happened. That makes this our territory. You want to stay? You pay tribute."

  "We're not paying you shit! This is a public park! You don't own it!"

  "Public's gone, kid. System owns it now. And we claimed it first." Derek smiled, and it was all teeth. "So either you contribute to our group's strength, or you leave. Those are your options."

  Jonah pushed through the outer ring of spectators. Nobody stopped him; people were too focused on the confrontation to notice one more body joining the crowd.

  "Third option. They stay, you leave, nobody bleeds today." Jonah stepped forward.

  Every head turned toward him. Derek's smile vanished, replaced with calculating assessment.

  "And who the fuck are you?"
