The Porter Between Two Worlds

In his previous life, spiritual qi revival swept across Earth, ushering in a great era of cultivation for all. Qin Yu thrived thanks to his talent in the cultivation era. His own mother, after setting her sights on the resources he possessed, teamed up with her gigolo boyfriend to spread rumors that he was hiding a treasure. Together with a group of greedy cultivators, they surrounded him. Qin Yu took them all down with him. Qin Yu never expected that the thing really was a treasure. After absorbing the spiritual qi scattered when the cultivators perished with him, it gave him a chance to be reborn and the ability to transmigrate between two worlds. With his ability to transmigrate between two worlds, Qin Yu started trading goods between them. The pretty but useless stones he traded for with candy, salt, instant noodles, clothes, and snacks from the locals in the other world became precious gems in Earth's jewelry stores. The century-old ginseng he traded for with a solar-powered rechargeable flashlight became the prized treasure of a pharmacy. The two worlds had different cultivation methods? He combined their strengths and learned from each. Before he knew it, Qin Yu had become a king in both worlds. Theme: Hold fast to your convictions and build wealth
