The Magician of the Moon's Journey to Salvation Begins from the Collapse

Su Qingzhou's life creed is simple: survive, become stronger, and have fun. It's a pity that the system doesn't think so. He was obviously just going to Fuyuki City for a summer job—oh, no, it was the Holy Grail War, but he was diverted into the Collapse World halfway. The system said he was the savior, but he said the system had recognized the wrong person. The system says yes, it's you, the reward has been issued, please check. So Su Qingzhou embarked on the road to save various worlds.
