Doomsday: I Have a Plant Guardian System

[Apocalypse] [Plants vs. Zombies System] Chen Tian wakes up to find that he has transmigrated to an apocalyptic world. Not only are zombies a threat here, but spirit beasts are just as dangerous! Chen Tian isn't worried in the slightest. A Peashooter in his left hand, a Cherry Bomb in his right, and a horde of zombies following behind him. Ordinary zombies can't even get close. What?! The System uses the Host's lifespan as fuel, and only spirit herbs can ease the drain?

From then on, Chen Tian struggles to find spirit herbs in the apocalypse.

The protagonist isn't bloodthirsty or a goody-two-shoes. There's only one female lead, and she appears late.

The protagonist won't just show off and slap faces.
