Gardener in the Apocalypse (A Plant Vs Zombie system Fanfic)

In this world, your class matter to your life. NO!, this is not a fantasy game-like novel introduction of how the weak class will amount to nothing in their world and somehow the MC with a weak ass class or classless will become OP. This is a zombie Apocalyptic world where those who have a strong class survive and weaker class died from the bizarre variation of zombie and monster in this world. What would happen when someone has a class of gardeners? They die! That's it. I mean, how do you think you are going to fight zombies with flowers and your plant? oh, wait! that is what our MC has done, taking inspiration from the Plant Vs Zombie game, he uses his gardener class to its maximum potential, killing zombies left and right. Author note: Well I honestly don't know how I am going to do this, I am just trying to create something that I really want to know as there is only 1 Plant vs Zombie related fanfic with the apocalypse that I know(but it is a fucking BL). Since no one really created one, I'm gonna created it myself. The ability will be modified to be similar(but not the same) to the garden warfare version of PVZ(plants are able to walk)(not in the beginning though). Of course, there is also limitation such as ......well it will be a spoiler right... just enjoy! Disclaimer: I don't own the "Plant Vs Zombie" game and its variation as they are all owned by POPCAP. I also don't own the cover pic as I just take the cover of the PVZ GW achievement background and add my title.
