Lin Xiao, an orphan who grew up in a shantytown in Jiangcheng, was extremely poor and relied on doing odd jobs and playing tricks to get by. He is mean-mouthed and thick-skinned, and occasionally does harmless and immoral things, but he values "loyalty" more seriously than his fate. One day, he offended a local gangster because of his "nosy" and was forced into a desperate situation. A drunken and slovenly old man suddenly appeared and used outrageous excuses to trick him into becoming a disciple.
After becoming a disciple, Lin Xiao's nightmare began. This master, who calls himself an "old drunkard", is addicted to alcohol, gambling, and loves to look at beautiful women. All the troubles he caused are blamed on Lin Xiao. Overnight, Lin Xiao was burdened with millions of "teacher debts." In order to pay off his debts, he was forced to learn ghost hunting, fortune telling, Feng Shui and other "arts and crafts" from unreliable masters, which opened the door to a new world.
He discovered that he had the rare "chaos body" and could learn everything quickly, but the master's teaching method was extremely deceptive - he took on the most dangerous jobs, made the most money, and then the master took 90% of it to fill the hole. Lin Xiao was "forced to do business" again and again, and got acquainted with ordinary people such as generous contractors and savvy antique dealers. He also met wealthy daughters and school beauties who were troubled by evil spirits. With his gradually awakening ability, he showed himself to others and got slapped in the face. However, every time the money he earned was harvested by his master accurately before he could warm it up, causing him to cry bitterly, "cultivating immortality is not as good as working!"
As his strength increases, Lin Xiao comes into contact with more and more powerful enemies: the Eastern Hidden Sect that covets China's national destiny, the Western Secret Society that masters black magic, and the small-time "Shinto Sect" that conducts evil human experiments.
