I Go Back and Forth to Show My Sword and Act as a Traitor

A box of Dove chocolates was exchanged for a Southern Type 14 pistol, which started Lin Feng's career as a traitor across time and space. Bound to the "Wanjie Mall" system, he jumped repeatedly between the war-torn sword world and the modern city - exchanging Yiwu small commodities for Japanese helmets, and using captured samurai swords to exchange for full boxes of penicillin at the headquarters. When Li Yunlong rubbed his hands and asked, "Brother, do you still have a flashlight that can illuminate the blind Japanese at night?" Lin Feng had become the most special material hub in the two worlds. But he soon discovered that this was more than just a get-rich-quick game. The system's cold reminders, the quietly accumulated "karma debt", and the shadow organizations trying to tamper with history, all pushed him towards a heavy truth: what he was trading was not only goods, but also a history that cannot be tarnished.
