  • Lin Ye explored the Red Maze, collected Mutation Organs and supplies, began upgrading his Shelter, and traded information with other survivors.
  • Lin Ye used the Abyssal Egg in a tunnel simulation to uncover intersecting time loops, connect the tunnel to the Abyss, and gain a Time Rule Fragment and a Gate to the Abyss.
  • Lin Ye’s Shelter reached Tier 1, restoring utilities and adding inspection functions, while he collected Mutation Cards and heard Mr. X warn that mutated creatures would hunt survivors after the Initial Stage.
  • Lin Ye completed a research-institute simulation, helped defeat Red-haired Caroline with an experimental weapon, and received the Human Evolution Map, Dr. Caroline’s Gift, and the All or Nothing title.
  • Lin Ye warned survivors that Site Missions had replaced the usual maze exploration, then boarded a bus and chose to leave it at a ruin-filled stop with Li Ji, Zhao Yong, and Xu Min.
  • Lin Ye fought his way to a gun shop, killed a Sheep-Headed Monster, and gathered weapons and supplies before reuniting with the others at Xu Min’s supermarket.
  • After a tide of mutated creatures attacked the supermarket, Lin Ye and the others ran out of ammunition and fought on the stairs, where Lin Ye’s Psionic Energy sharpened his blade work as another group of monsters charged in.
Chapters 1–25 Vol. 1 Read

Ch. 1Starting out as a Class-D Personnel

Lin Ye examined his new doomsday shelter and discovered that his talent let him simulate a Class-D personnel on a mission. He entered a simulation as Kenneth and watched the first prisoner get sent into a villa, while the remaining simulations were limited to ten.

  • Lin Ye checked his system, learned his shelter was safe for seven days, and found that his Class-D Personnel Simulator could run one mission simulation each day.

Ch. 3Abyss Box

Lin Ye closed the Abyss Box in the simulation, saving the area and earning a reward that included one use of the real box. He opened it in the Shelter, where the system neutralized its dangers and let him choose from the bizarre objects that spilled out.

  • Lin Ye entered the villa first and died when a red-eyed figure transformed his body, then concluded that the first person inside was certain to die.
  • Lin Ye entered after Number One, rushed upstairs, and closed the Abyss Box despite the Captain's warning and the presence approaching behind him.
  • The simulation ended, awarding Lin Ye six items, Abyss Box use authorization, and the title Savior.
  • Lin Ye found an orange specimen of a reassembled human body among his rewards and read that the Savior title improved his treatment as Class-D Personnel.
