Manga Like Wo Zai Yijie Dang Daheng

In the modern world, Xu Fei is an ordinary three-no college student: no looks, no money, and no future. But in the other-world, he is a martial artist, a cultivator, and a magician. The other-world martial arts skills make him unbeatable in the modern world, but it's not like an overwhelming super-power. The other-world resembles ancient times, where medicine, economics, and political systems are still primitive. Being able to travel between the two worlds, Xu Fei will use his unique skills to pick up women and become a tycoon in each world!
