My name is Lu Chen, I am a 23-year-old programmer. I woke up in a doomsday world. Three blood moons hang high, the gray mist swallows everything, the living mutate, and the dead are resurrected. This is not the earth, but a mysterious wasteland in parallel time and space.
I have a sign-in system, and draws are drawn at midnight every night: equipment, skills, summons... The price is lifespan, or attracting "their" attention.
Broken mechanical arms, sonic weapons, weird rules... I met Cen Qi in the quantum tower, rescued Adai at the neural bridge station, and met the singer Xuanzhen again. She said that I was the "key to be sacrificed."
The team is formed, black technology is revived, and the Ark plan emerges. But when you sign in for the 20th time, the system prompts: "You are the core of the game."
Now, the observers are targeting me, the future version of myself, and they want to kill me and silence me. Escape or fight?
