Global Mutation: Killing Corpses and Upgrading Me to Promote the Apocalypse

The red moon comes and the world changes. Zombies are rampant, order has collapsed, and human nature is vulnerable to interests. Neighbors push someone into a corpse's mouth for half a piece of bread, and a companion stabs someone in the back for a bottle of mineral water. Repaying kindness with hatred is the norm in the apocalypse. Everyone is desperately waiting for military rescue, but they don't know that the official system is already overwhelmed. Lin Chen awakens the killing upgrade system. Killing zombies and evil people can increase experience, improve attributes, and unlock magical skills! No Holy Mother, no soft-heartedness, no nonsense, you will die when you strike, and you will kill decisively. The tide of corpses is a pool of experience, and evil people are stepping stones. Anyone who dares to offend his forces will be crushed into dust! From the neighborhood tyrant, to the lord of a city, to the supreme murderer who is pushing for the end of the world. I, Lin Chen, have the final say in this hell on earth!
