Global Mutation: My War Chariot Upgrades Without Limit

[System + battle pets + apocalypse + leveling up + monsters + combat vehicles]

An invincible, feel-good power fantasy!

More than a century ago, a super cobalt bomb was detonated, bringing global catastrophe.

Over a hundred years later, Lü Yang joins an expedition team to explore the surface and survive. From the start, every other team member is killed, but fortunately he awakens a System in time and gets a combat vehicle that can be upgraded without limit through sign-ins.

Against invaders from the Three Indias, Japan, Korea, the United States, and elsewhere: kill, kill, kill!

Against mutated humans and beasts: kill, kill, kill!

The protagonist is brutal. Cowards, stay away!
