This is the floorboard of an unknown creature, whose image description can be found in ancient books in China and word of mouth of rural people. Its shape is similar to that of a zombie in folklore. According to legend, once Hiderigami appeared, it was bound to be accompanied by drought. Hiderigami is an extremely rare high-order zombie, and its ability is second only to the highest-order "_" surrendered by Guanyin Bodhisattva.
Extended data:
During the Ming and Qing Dynasties, the view that heroes are zombies was widely accepted, and the customs of begging for rain such as "fighting dry bones" and "burning heroes" became popular. People in many places think that Hiderigami is a dead body. Once there is drought, they should go to see the new grave. If there is a fire on the grave and the body is covered with white hair after being dug up, it is Hiderigami. Only by destroying it can the drought be solved.
But a dead body covered with white hair should only be white and stiff. Hiderigami is not afraid of the sun, and there is no need to hide in the grave during the day.
The word Hiderigami stands for drought in Japanese.
