Comprehensive Martial Arts: a Journey into the World of Martial Arts

Wan An was unlucky because he died young, but he was lucky because he traveled through time. The bad thing is that he has traveled to a world of mixed martial arts where people fight and kill if they disagree with each other. The good thing is that he has a sales system with him. However, in addition to being useless for buying and selling, this system also has to perform system-defeating tasks from time to time. For example, selling the Dragon Spirit and Tiger Pill to Lu Xiaofeng: Lu Xiaofeng looked at Wan An for a long time, then suddenly brought him into the room: "I think I need to prove to you whether I need this thing or not." Wan An hugged himself with a look of horror on his face: "I sell my goods, not my body! Don't mess with my money!" For example, selling "One Wash" washing powder to Ximen Chuixue: Ximen Chuixue's eyes were heavy as she silently accepted the bag of washing powder... There are so many worlds, so many choices, and the things sold are all kinds of weird. Intention: Live hard and you will have love and wealth.
