追放された俺、植物チートで復讐す

A virus turns the world into a zombie wasteland, and a man with a plant-evolution system is betrayed and exiled by his wife and her lover. He builds a green oasis, rescues a city lord’s daughter, and survives attacks as enemies weaponize the undead. When a food scam threatens survivors, he exposes it and rises as the savior of the dead world.
