Apocalypse Zoo: I Thought I Was the Keeper, Turns Out I’m the Pet

[Decisive and unwavering in killing + Beast Taming + Global Evolution + No Rebirth + No Female Lead + Strong Protagonists] The end of the world is coming, human civilization collapses, species evolve wildly, and ferocious mutant beasts and zombies are spread all over the world. Shen Nian Ze awakened the system. I thought I could punch the zombies in Nanshan and kick the strange beasts in the North Sea, but it turns out my ability is animal evolution and understanding animal language? While the survivors are struggling to survive among zombies and mutants, Shen Nian Ze owns a dilapidated zoo. So, the style of painting changed completely: Shen Nian Ze originally wanted to develop in a low-key manner, but his employees were more enthusiastic than each other, feeding him like crazy and forcing him to stand on the top of the world. The Siberian tiger's small mouth shattered the tank-sized mutant with a claw and threw a crystal core at it: "Upgrade quickly." The lion Ah Shi lazily lay at the gate of the base, facing the foreign enemies with a cold look: "We are just a handful of people, who are you looking down on?" Black Panther Heizi appeared silently on the wall: "All threats within three kilometers have been eliminated." The giant python Dabai slowly tightened its body, using it to create a safe zone: "Don't get close to me... uh, don't get close to my boss." Brown bear Panda came over with a bucket of mutant honey: "Boss! Come and have some!" Shen Nianze: "No, everyone, who is the breeder?" I wanted to conquer the apocalypse with my pets, but ended up being raised to be the biggest gigolo in the apocalypse. This is a lighthearted (?) story about the beast kings who are madly competing with each other, desperately trying to feed their precious humans, and by the way, bringing about the end of the world.
