Suck each other's blood as food. First of all, zombies are mummified corpses in a sense, and human blood is a fine product for zombies, and zombies can rely on it to maintain their lives and enhance their own abilities. Secondly, for zombies, it is also a kind of cultivation of their own mana, just like human beings taking Dan medicine or setting traditional stories, which makes the image of zombies more horrible and vivid, just human imagination.

Zombie origin

Legend has it that the earliest zombie was Hiderigami, the daughter of Xuanyuan Huangdi. Because of the curse of Chiyou, she became a zombie. Originally, zombies don't need to suck human blood, because there is too little aura in heaven and earth, and people are the soul of all things, so they need to suck human blood.

The word "zombie" comes from Daqianlu, a Taoist book. Zombies are stiff limbs, head not low, eyes not oblique, legs not divided, and body not rotting. Zombie theory prevailed after the middle of Ming and Qing Dynasties. Most people recorded zombies in Qing Dynasty, Yuan Mei's Woods Language and Ji Xiaolan's Yuewei Caotang Notes were the first two, which can be said to be complete works of zombies.

Zombies are divided into many grades, namely: purple stiff (zombies who died soon after, their bodies are lilac, so they can't move freely), white stiff (dead bodies are white, moving slowly, afraid of light and fire), green stiff (giving off the smell of green corpses, jumping fast, only afraid of sunshine), and hairy stiff (dead bodies have long hair, moving quickly, jumping on trees like flies, not afraid of fire and fire).
