Xiao Ran transmigrated to a fantasy world. As a dungeon guard in the Celestial Dungeon, with a special floor called the Purgatory meant for powerful demons and martial arts experts, he faced a huge challenge from the start. The Eldest Princess acquired a forbidden martial arts technique and was banished to the Purgatory. However, no one was powerful enough to restrain her. All the dungeon guards were defeated. Xiao Ran stepped up and declared, “Your Highness, it’s better for you to behave yourself on my territory” and effortlessly subdued the Eldest Princess.

He progressed from imprisoning the Eldest Princess to delivering the Great Xia Kingdom from the evil clutches of various demons and evil martial arts experts.

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!!
