- Description from novelbuddy

Amamiya Hiroto is unlucky. His life consisted of misfortune after misfortune, culminating in an unlucky death during an incident on a school boat trip, trying to save a girl he barely knew. After death, he met a god of reincarnation who requested that the hundred or so dead passengers—one of them being the girl he tried in vain to save—be reincarnated into another world.

Li Muyang had transmigrated, and the good news was that he had a system. The bad news was that this system could only be used to play games. Oh well, if it’s playing games, then so be it. It’s better than having nothing. In the game, he was powerful and mysterious, causing the extraordinary fairies to be shaken to their core. Since it’s just a game, there’s no problem in aiming for the full compendium route, right? It wasn’t until one day that the fairies from the game showed up at his door that Li Muyang was truly startled. What was supposed to be just a game, how did it become real? “So... listen to my excuse!” I was really just playing a game!!
