Shen Jin is a delivery boy in the urban underground black market, and his ancestral silver needles and medical scriptures are regarded as junk. During a delivery, he rescued a "certain patient" who was poisoned, but was framed as a stolen auction item by a wealthy young man. When he was surrounded, the space ring recognized its owner. It contained a medicine field, a broken scroll, a star gate broken formation, and a young divine beast sealed inside. Shen Jin exposed the chronic poison on the spot and saved the only grandson of the black market boss with three injections, and the boss recognized him in public. The next second, the ancient sect's trial monument came and forcibly pulled him into the game. As long as he can pass the first question, everyone is waiting to see the waste. However, he relies on the power of cause and effect to trace the cause of the disease, locate weaknesses, walk in the void and cheat all the way, collect mythical beasts, defeat geniuses, step on wealthy families, and finally overthrow the star field passage bureau set up by the sect's senior officials.
