The apocalypse is coming, and all human beings are bound to the survival system. 22-Year-old Yu Sheng firmly refuses to activate it because of her grandmother's last words. She sold her house and stocked up on goods and built an underground fortress with her inheritance. The brass pocket watch left by her grandmother could actually read system conversations, helping her take advantage of the information. She evaded system surveillance, fought back the host alliance, fought against the zombie wave, and gathered partners who also refused to activate the system to form an alliance. Facing the ultimate BOSS at the core of the system who wants to devour the pure soul, Yu Sheng awakens the power of the pocket watch and leads everyone to seal the system and end the plunder, allowing human beings to break free from the shackles of the system and start a doomsday rebirth with both hands.
