In Order to Go Home, I Was Forced to Save Another World

[The end of the world + Cthulhu + no heroine] When Li Xiu was playing "Soul Knight", he suddenly traveled to a different world and got a game panel that was very similar to "Soul Knight". In order to return home, he was forced to save a different world that was already at the end of the world. (Ps: The game panel obtained by the protagonist is modified based on the Soul Knight Magic, please be careful if you mind)
