My City Connects to All Worlds

Chen Xiaofeng, a good-for-nothing young man, accidentally acquires a city that can communicate with the Myriad Worlds. From ancient times through every era that follows, Chen Xiaofeng can be found there. Then come the worlds of martial arts and immortal heroes. The worlds are divided into four tiers: low-level ancient mortal worlds, mid-level martial arts worlds, high-level modern worlds, and super-level immortal hero worlds. The protagonist can obtain resources, secret manuals, cultivation techniques, and more from higher-level worlds.
