Raise the level in the Multiverse

An ordinary guy, gets a system in real life-Solo Leveling. There are other gates in the dungeon? So they still lead to other worlds!? Then our Russian guy should go to a new level! (A/N) Fan fiction is made for entertainment purposes. I own only my hero, and the rest of the characters from various anime/manga belong to their owners. The schedule for the release of chapters has not yet been determined. * Warning* The main character-at times will violate all the laws of physics. There may be some differences with the canonical plot from other works. It is written for the soul and distraction from other worries.
