Lin Beichen, an ordinary young man who just graduated from a third-rate university, is lazy and easy-going, but he has a stubbornness that refuses to admit defeat. His parents died young and he made a living by doing odd jobs. He rented a dilapidated apartment in a village in the city. Everyday he was pressed for rent by the landlord and blamed by his colleagues. He was a typical "little transparent person at the bottom of society". His biggest hobby is playing the mobile game "Call of Destiny", but he has very bad luck. He always guarantees his bottom line when drawing cards, and is ridiculed by the guild as the "King of Non-Chiefs". However, an accident activated the "qi circulation system" in the body, and his life was reversed. On the surface, he remains low-key, but in fact, he secretly uses the European Emperor's operation to crush everything. He has gradually grown from a despised salted fish to a "luck master" in the urban supernatural world.
