The Apocalypse Hasn't Come Yet, Why Did You Reach the Level Early?

"It has been detected that the apocalyptic trial has been started in advance, and the tenfold profit bonus has been pre-activated!" Nine days before the end, Zhao Jun broke the neck of a mutated zombie with his bare hands in the hospital lobby. Experience skyrocketed! Gold coins explode! The best equipment blueprints are available! With thirty years of combat experience in his previous life and the SSS-level talent [Lord of All Poisons], Zhao Jun embarked on a crazy rampage before the end of the world. Abandoned virus samples from hospitals? Suck! Out-of-control infected people imprisoned in the basement? Kill! When everyone knew nothing about the coming disaster, Zhao Jun had already taken steps to build his strength to a height that was beyond the reach of ordinary people. Do hypocritical colleagues dare to plot against you? Destroy it with one slap! The arrogant rich second generation dare to speak rudely? Directly teach you how to be a good person! Doomsday never depends on planning, only on survivability. When the blood-red countdown reached zero, Zhao Jun stood on top of the city, overlooking the world that was about to become purgatory. He has already passed this game called Doomsday ahead of schedule!
