After Li Qingshan got divorced and left home, he unexpectedly obtained the Xuantian Ring at a Taoist temple in the wilderness, unlocking the ability to travel between two realms and store items. He exchanged modern instant noodles, refined salt, medicine and other supplies for scarce resources such as ginseng, Ganoderma lucidum, and spiritual stones from other worlds, and started a career as a traitor in both worlds. By relying on honest transactions, he won the trust of the villagers in Zhangjia Village and established a stable exchange channel. He also absorbed the immortal energy transformed from the spirit stones to strengthen his physical body, practice exercises, and transformed from an ordinary person into a strong body refiner. He resolved crises such as robberies and underworld blockades, accumulated huge wealth in the trade between the two worlds, and finally achieved a counterattack in life and lived a wonderful life.
