The Huanglin of the Northern Barbarians was once home to spirits and monsters, and there were many spirits and monsters gathering in them. The so-called spirit demons are the aggregation of the spiritual energy of heaven and earth. They do not know good and evil, and can be imagined and transformed. They have practiced for hundreds of years to transform into objects and thousands of years into humans. The thousand-year-old spirit demon has a spiritual heart. It is said that using the spiritual heart as a guide and the bamboo as medicine can cure all the diseases in the world, and even save people between life and death.
