Lin Qi traverses into the Cyber World and is fortunate enough to bind with a two-way traversal Door. Behind the Door is a doomsday city world, where Zombies run rampant and monsters wreak havoc. The Doomsday World possesses Extraordinary resources scarce in the Cyber World, and its Extraordinary Power is in a nascent state. During the day, as a corporate wage slave in the Cyber World, he is brutally hunted across the globe; at night, he travels to the Doomsday World to build and fight monsters.
