I Open Plug-Ins for Zombies

The end of the world is coming, and zombies are rampant. Killing zombies can strengthen your body, start evolution, and obtain superpowers, weapons, etc. How unfair is it to zombies? The protagonist possesses the "Zombie System of All Worlds" and becomes the boss behind the zombies. Do you want to kill zombies and protect flowers? Sorry, zombies are not something that just any weakling can kill. Do you want to accelerate your evolution and become a big boss? Joining forces to build a city-state? Feel sorry! The boss behind the zombies disagrees, you are nothing! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
