I'm a Necromancer, and My Zombie Is a Cute, Airheaded School Beauty

On September 7, the Ghost Festival arrived, and a blood moon hung in the sky. The apocalypse descended. Zombies overran the land, and the human world became a living hell. I, Li Haotian, had transmigrated into this parallel world. Even worse, I had inherited the body of an autistic person who had starved to death! Just as I was losing hope, a Necromancer System suddenly appeared in my mind, allowing me to cultivate by forming a contract with a soul-bound undead. Then a pure-looking female zombie flashed past the window… I, Shen Weiwei, am Mingcheng No. 1 High School's adorable, spacey beauty. But I'm not really spacey. I'm just a little socially anxious! I got bitten by a zombie in an accident. Boohoo, it hurts so much! Huh? That's strange. Didn't I turn into a zombie? Why can I still think for myself? Wait, who is he? Why is he taking off my clothes? Oh my God! H-he actually wants to bathe me!?
