Monstro-Apocalypse allowed cultivation love with Sister

CAUTION: [Taboo Fetish Focused Work] The story of a boy named Thanatos Pierce, who finds himself totally screwed by an apocalypse of zombies, monsters, and other powerful creatures. Fortunately for him, he is looked after by his older sister, who has prepared him in advance for the challenges ahead. Behind her hidden knowledge and all the chaos lies a secret that Thanatos will try to unravel. ________________________________________________________________________________ In this story, the MC is far from stupid, and his entourage will also have brains. The main thing is not to have too big and smart brains, otherwise zombies and monsters will gather in a horde and eat them! Or maybe a mysterious fog will consume the inhabitants of the surviving settlement and eat their brains... oops, spoiler.
