The early summer evening breeze was slightly cool, and Su Yuan instinctively wrapped his coat tighter around himself.

  Ye Haoyu walked ahead with his hands in his pockets, his expression stern. His muscur build, coupled with his towering height of over 1.9 meters, made him look like a human tower, drawing attention from passersby.

  Suddenly, he stopped, turned to look at Su Yuan, and asked with a complex expression on his face, "Old Su, what was the answer to that question just now?"

  Su Yuan was waving his hand in front of him as if swatting away flies. He replied casually, "It's 0 seconds."

  "0 seconds?" Ye Haoyu frowned, "Are you anemic?"

  Su Yuan stumbled, nearly falling ft on his face.

  "Hahaha..." Younger Sister clutched her stomach, ughing like a goose.

  "It's not that I'm anemic; the information in the question was meant to mislead," Su Yuan patiently expined. "After all, as the bloody writing said, the head should have been removed before the chest was cut open."

  "Oh! Fuck, it was a brain teaser, wasn't it?"

  Ye Haoyu sighed in relief, his stern expression quickly turning into a goofy smile, "I thought you were actually good at math..."

  "...What do you mean?" Su Yuan was a bit confused.

  "I was worried you were secretly studying," Ye Haoyu said. "We agreed to be sckers together, and if you're secretly studying at night, I won't even be able to enjoy my games.

  The sound of your games at 2 AM is music to my ears, but your secret diligence keeps me awake at night..."

  "Wait a minute," Su Yuan felt a bit dizzy, "If the question on the bckboard was a math problem... shouldn't it be simpler? Anyone could solve it, right? Why would you need to study secretly at night?"

  "Who says so? I can't solve it."

  Ye Haoyu said loudly, completely unaware that he had been expelled from the realm of humanity, "I get dizzy just looking at those numbers. During the elementary to middle school advancement exam... I only scored 25 in math!"

  Su Yuan was speechless, not knowing what to say.

  That 25 was probably from the multiple-choice questions...

  Su Yuan sighed, "Forget it, let's talk business."

  "Alright!" When it came to business, Ye Haoyu put away his smile and became serious, "Everyone went to check just now, and the cssroom projector wasn't even plugged in. Plus, that old thing is so blurry, it couldn't possibly be that clear.

  The bckboard is just an ordinary bckboard, no high-tech involved... The css monitor even asked in the office, and Mr. Zhang didn't come tonight at all!"

  Su Yuan nodded, "I also asked other csses, and everything was normal for them. Only our css had the bloody writing."

  "That's strange."

  Ye Haoyu rubbed his chin, "Bloody writing appearing out of nowhere... Old Su, do you think there really are ghosts in this world?"

  Ghosts?

  In this materialistic era, normal people would scoff at such a question.

  But Su Yuan fell silent...

  He gnced at the young girl standing not far in front of him.

  The girl was about seventeen or eighteen, with clear, bright eyes that held a hint of mischief. People passed through her body in small groups, giving Su Yuan a sense of unreality.

  After a pause, he said, "Maybe... there are."

  ***

  The two returned to the fifth floor of the boys' dormitory.

  The school's dormitory building was newly constructed this year, with a total of five floors.

  Each dormitory housed six people, with fourteen rooms on each floor.

  Since the floors were arranged according to css order, Css Ten's dorm was on the fifth floor, and only rooms 501 to 505 were occupied on the entire floor.

  In other words, the entire fifth floor was occupied by their css alone.

  Perhaps it was psychological, but the familiar corridor felt particurly eerie and terrifying to Su Yuan today.

  There was no light at the end of the corridor, only endless darkness, hiding unknown dangers.

  Su Yuan shivered, pushed open the door to room 502, and walked in.

  The room was empty, except for a short boy standing on the balcony, hanging clothes.

  He was less than 1.6 meters tall, standing on tiptoe and jumping, unable to reach the clothesline.

  His name was Qi Yinhong, the dorm leader of room 502.

  Seeing the two, Qi Yinhong quickly called out, "You two came just in time, give me a hand."

  Ye Haoyu didn't waste words, walking over to lift him up.

  "Brother, your friend is silly. Why doesn't he just help hang the clothes instead of lifting someone up?"

  Younger Sister ughed from Su Yuan's bed.

  Su Yuan shook his head and whispered, "You don't understand, this way he gets a sense of fatherly satisfaction."

  He said, pulling out his phone from under the bed and checking the screen.

  10:03 PM.

  Less than twenty minutes until lights out...

  "Where are Gao Wenyi and Zhang Yang? Haven't they come back yet?" Su Yuan frowned.

  Qi Yinhong pouted, "They went to room 503 to join the fun. A bunch of people are gathered there discussing ghosts or something. Don't you think it's crazy?"

  Room 503 was where Mao Houwang stayed.

  Ye Haoyu put Qi Yinhong down, patting his head with a fatherly affection, "Hong'er, you're not joining the fun?"

  "Screw you, stop taking advantage of me!"

  Qi Yinhong impatiently swatted away Ye Haoyu's hand, "What's there to see? Do you really believe in supernatural events?"

  "It's just a prank. I don't know what trick they used, but I'd sooner believe in an alien invasion than ghosts..."

  Before he could finish, Su Yuan had already stood up and walked out.

  "I'm going to check it out."

  "Wait for me, Old Su, I'm coming too."

  Ye Haoyu quickly followed.

  "Don't go, you two aren't allowed to go!"

  Qi Yinhong watched their backs, hopping in frustration, "Come back and clean up, or don't expect to eat my snacks again!"

  The only response was the "bang" of the door closing.

  ...

  The corridor was empty, and as Su Yuan pushed open the door to room 503, a rather handsome boy was rushing out, covering his nose, with a trail of white smoke behind him.

  "I can't stand you stinky guys anymore! Cough, cough... Brother Su?"

  This handsome boy was Gao Wenyi, Su Yuan's dorm mate. After greeting him, he fled, "I'm out of here, Brother Su, I can't take it!"

  "Can't take it?" Su Yuan frowned. What on earth were they doing in there?

  He and Ye Haoyu walked into the dorm, and the scene before them took them by surprise.

  The room was filled with smoke, a group of people gathered in the center, unable to see each other's faces, as if they were in a sauna.

  Css monitor Zhou Yulong stood in the center, wiping his tears, "Stop arguing, can you put out the cigarettes first, cough, cough..."

  "Fuck, how can we talk about something this big without smoking... cough." A dark-skinned boy with a quiff spoke up.

  But he didn't look too good either, with white smoke rising from his head. He couldn't tell if he was inhaling his own smoke or someone else's secondhand smoke.

  "Zhou the Cripple, open the windows to let the smoke out."

  "Cough, cough... Okay, Brother Fei!"

  Zhou Chang, squatting in the corner, immediately stood up and hobbled over to open the window.

  As the balcony's floor-to-ceiling window opened, the smoke gradually dispersed, and everyone could finally see each other's faces.
