Lu Mian, an apprentice at "Zhiweixuan" in the antique street, has a secret that no one knows - when he praises people, the system will make a lot of money. He praised the boss for finding a broken bowl that was a real dragon spring, which was worth 50,000 yuan; he was praising his opponent for mistaking the bronze mirror that was a sea beast from the Tang Dynasty, and it was worth a mysterious copper coin. But the system has an iron rule: it must come from the heart, otherwise nothing will be gained. What's even more bizarre is that after falling asleep every night, he will fall into the "Dream Realm" - a replica world woven by the remaining obsessions of the five folk immortals. Fighting monsters in the dreamland will reward you: the scales of the Willow Fairy allow him to see at night as if it were daytime, and the beards of the Gray Fairy give him psychic hearing. However, the Dream Realm has cruel rules: each time you enter a dream, the upper limit is fifteen minutes, and you will be in a deep coma if you exceed the time limit; every time you obtain a physical enhancement, the chance of attracting evil spirits in reality doubles. Lu Mian originally just wanted to pick up leaks, save money, and open a small shop in peace. But when the elder Fox Immortal came to him and told him, "You are the Descendant Dreamwalker, and the seal of the Five Immortals is loosening," he realized that those shadows peeping at him late at night were not hallucinations. Tonight, in his dreamland, a pair of golden vertical pupils opened.
