Man in the Holy Grail: Burn the Old Bug at the Beginning

Chu Yun, who was reborn in the world of Xingyue, developed insignificantly for seventeen years with the help of the system and finally burned the old insect to ashes before the fifth war. Chu Yun, who originally thought he had a master by his side, thought that this time the Holy Grail War was stable, but he found that this time the five battles seemed to be a little different from what he imagined. "???" Can anyone tell me why Matthew appears in the fifth battle? And is Gudazi, who gave King Heiwu a concussion with one punch, really human? In short, due to various mistakes, Chu Yun inexplicably became the only surviving master of Chaldea, shouldering the heavy responsibility of saving humanity. ..... Looking at the various heroic spirits behind him, Chu Yun had a wry smile on his face. "You really have to believe me. In the beginning, I just wanted to marry my girlfriend after five battles. Really!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
