She Has Allergies and Is a Picky Eater, so I Have to Raise Her.

[Apocalypse + Yandere + Pure Love + Vampire] Silver dust enveloped the sky, and the lower city became a biological filtering field filled with poisonous gas. Xu Ling was abandoned as an experimental subject. The broken body caused him to transform into a rampaging high-metabolic furnace, always on the verge of being burned to death by his own body heat. Until he was deep in the garbage dump and awakened the true ancestor of vampires - Sylvia, who was extremely allergic to the entire wasteland world. His body was her only antidote to survive in this toxic world. Her squeeze and coldness were his only salvation to calm the internal combustion in his body. The incomplete products of the two worlds have reached the most extreme symbiotic contract. Facing the pursuit of various forces, Xu Ling transformed into a violent undead blood dog and paved a bloody road with the bones of her enemies. The sick and arrogant true ancestor stepped on the stumps on the ground and declared his sovereignty indifferently. "Even a drop of blood is my private property. Whoever dares to peep, I will take away his life." This is a counterattack of defective products starting from the bottom of hell, and they will work together to kill through this decaying sky.
