In 2041, a twelve-hour countdown will appear on all screens around the world at the same time.
[The surface cleanup process is about to begin.
[All intelligent life forms are invited to enter the underground refuge area.
Twelve hours later, white light swept across the sky, and all life left on the surface was wiped out.
Cold storage maintenance worker Lin Chuan followed the crowd and fled underground, only to find that the so-called refuge area was a strange city full of rotting corpses, strange beasts and strange spores.
After killing the rotten corpse with his own hands for the first time, three cards appeared in front of him:
[Painless] [Corruption Resistance] [Bite Strengthening]
Only then did Lin Chuan discover that whenever he killed a life that had never been recorded for the first time, he could choose one of the opponent's core characteristics to make a unique card.
But more dangerous than the monsters is the underground city itself.
Not long after entering the underground, Lin Chuan discovered a line of modern simplified Chinese on the wall:
Don't trust the light here.
The question is, who else had been here before them?
