After Lin Wan lost his job, he tidied up his ancestral home and accidentally activated his Pisces Pendant and traveled to Qingxi Town in Dayong. He witnessed the suffering and lack of materials of the ancient people. He experimentally exchanged modern lighters for scraps of silver. After tasting the benefits, he began to systematically exchange things for things: he exchanged cheap daily necessities for ancient precious metals and antiques, quickly accumulating wealth in the modern world. At the same time, due to the lack of medical treatment in ancient times, he used medicines to help the ancient people, met the squires, hunters, and petty officials of Qingxi Town, and gradually built his own people. As the scale of trade expanded, it attracted the attention of ancient officials, chambers of commerce, and barbarians. Encountered difficulties, interceptions, and temptations, Lin Wan relied on modern knowledge and time travel advantages to resolve the crisis, established a secret caravan in ancient times, and established an antique trading company in modern times to realize the exchange of resources between the two worlds. In the end, he not only achieved freedom of wealth, but also secretly improved the people's livelihood in Qingxi Town, guarded the secret of Pisces Pei, balanced the relationship between the two worlds, and became an invisible overlord of trade between the two worlds.
