"I Sermonized in Zhongnanshan Mental Hospital" tells the story of Chen Zhuo who was sent to the Seventh Rehabilitation Center deep in the Qinling Mountains and discovered that this place was actually a secret stronghold where the "Myth Container" was imprisoned. The patients seem to be crazy, but in fact they are special people carrying the power of Chinese and foreign myths: the crazy monk hides the magical power of Journey to the West, the blind old man is the host of Odin's right eye, and the kimono girl can summon shikigami.
Chen Zhuo awakened the "Dharma Seal" power. He drew a Taoist talisman with his left hand and made a Buddha seal with his right hand. There was also a manic power similar to that of the Monkey King sleeping in his body. He gradually learned that the deviation of the "beacon" in the high-dimensional universe triggered the advent of myths, that the mental hospital was the last barrier against the gods and demons from outside the territory - the caregivers were descendants of Zhen Yuanzi, the head of Apollo was locked in the underground ice cellar, and the food in the cafeteria was mixed with dead branches of the world tree.
When strange beasts such as Yamata no Orochi and Fenrir wolf appeared in the world, Chen Zhuo teamed up with his fellow patients to fight against them. They fought from Zhongnan Mountain to the East China Sea, killed Hermes who transformed into a network virus, and fought against Prometheus who was parasitic in a nuclear power plant. As the battle deepened, he discovered that the divine power in his body was an ancient seal, and what was recorded in "Journey to the West" was not a myth, but a real record of the war between pre-civilizations and high-dimensional chaos.
In the end, Chen Zhuo broke the shackles of myth and used his mortal body to lead the "madmen" to crush the fire of chaos that devoured the galaxy, proving that human civilization can control its own destiny without relying on gods and Buddhas. Outside the rehabilitation center, new anomalies are still gathering, and their battle is far from over.
