Programmer Lin Yuan died suddenly while working overtime. When he opened his eyes, he turned into a little demon patrolling the mountain who was about to be beaten to death by Sun Wukong at the foot of Five Elements Mountain. On the verge of death, he awakens his destiny's golden finger, the "Illustrated Book of Gods" - it contains the magical powers that can be stolen by demons and gods, and the heavenly realm can be unlocked by transforming demons. He did not save the White Bone Demon to deceive Tang Monk, but took him as the "White Bone Goddess" and learned the Thousand Faces Transformation; he enlightened the Black Bear Demon not to steal cassocks, but to consecrate the "Black Wind Mountain Monarch" to control the Samadhi Demon Fire; he also formed a causal bond with Sun Wukong five hundred years in advance. When the scripture-seeking team finally headed west, he had built the "Ten Thousand Demons Pavilion" to house seventy-two cave demon kings, and the secrets of the ninth level of the catalogue, the realm of "conferred gods", gradually emerged - this map was originally a thing left behind by the ancient conferred gods. It can be used to redefine the god's position and open the gate of heaven. This time, the fate of Journey to the West will be written by the demon!
