A casual version: An immortal monster who has lived for 100,000 years, whose soul is integrated into a modern high school boy, steps back into the urban campus, plays dumb to eat the tiger, makes up for the regrets of his past life, acts cool, picks up girls, dominates the city, and specializes in treating all kinds of不服. Formal version: Living for 100,000 years, the sea has changed into mulberry fields; returning to seclusion in Zhongnan Mountain, looking indifferently at the world. He once went to the west to obtain scriptures with Tang Monk; he once called Sun Wukong his brother! He was once the emperor's teacher of Qin Shi Huang, and he once called Liu Bang, the Han Gaozu, his brother. He has seen the sea turn into mulberry fields, and he has also seen the mountains turn into plains.
