In the stone murals of the Orochi Tomb of the Eastern Han Dynasty, there is a strange picture of the arrival of a spaceship. Lin Shen, an agent from the Asian Bureau of Decryption, encountered a strange change. His female partner's soul left her body and went straight to hell to get the soul of the big snake Wang Mang.
