Legend has it that after a zombie becomes a demon, it turns into a demon. After transforming into a demon, the zombie can fly, also known as flying zombies. It is said that it can kill dragons, swallow clouds, and walk like the wind. Wherever he goes, he is the king of zombies. The "Shenyi Jing" records: "There is a man in the south, two or three feet long, naked, with two eyes on top, walking like the wind, named Ba. The country he saw is suffering from a severe drought, and the land is thousands of miles away." The monster transformed into a zombie that could fly, killed dragons and swallowed clouds, causing drought. Therefore, whenever there is a drought, people will search for zombies and burn them to ashes. According to legend, flying zombies can also suck human blood within a hundred steps.
