Star Vault: Let Huang Quan Participate in the Holy Grail War!

[Bengtie+fate+partial settings magic modification] My name is Lin Yuan, an ordinary magician. Due to an accident, I came to Fuyuki City and participated in the Holy Grail War. I originally thought I was going to die, until when I was summoning the heroic spirit, Huang Quan was actually summoned! I thought this was outrageous enough, until I saw Xing, March Qi, and Dan Heng coming to my door at Tohsaka Rin's house. Only then did I realize that what I had come to was not only Xingyue, but also Bengtie. The world seemed to have become more dangerous. … Ps: Because the fate world is a place that even the pioneering star god Akivili has never reached, the influence of fate will become extremely slim. Therefore, Star Iron's characters will be weakened differently to avoid directly exploding stars with one move. That would be no fun and no process. Another thing is that nothing happened to Sakura, which will be explained later. [The Five Wars refers to the Fifth Holy Grail War, and the first one to start is the linkage line between Bengtie and Fate, the UBW line. [Those who have never watched Fate can get started without any pressure. I will try to make Fate's world view as simple as possible below.
