Parallel Universe Travel System

Otaku Wu Tian got a parallel universe system, and from then on he embarked on the road of picking up girls in various planes and upgrading. There are cities here, there are martial arts, immortals, and animations, but the IQ stories of limited authors are basically set in China. This is the first book for a novice. It is definitely not very well written, so don't criticize it if you don't like it. . . This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
