Doomsday: My System Mutated

Guan Wen, an ordinary overworked office worker, woke up one day and accidentally discovered that he had transmigrated, and that the world was ending.

Monstrous beasts had descended across the globe, and the planet's creatures were mutating. No one could survive.

But he soon found out that everyone in this world had a cold weapon System. By fighting monsters, people could grow stronger and stay alive.

Guan Wen thought he would have to join the monster-hunting masses, but who could have guessed that his System would mutate into a Gun God System equipped with firearms?

From then on, blowing an enemy's head off with a single shot from eight hundred meters away was no longer a dream.
