Ultimate Class 1: Stop Making Trouble, Is KO1 a Muggle?

(Daily plot + semi-invincible flow + not dismantling Dongting CP + second creation + making up for regrets) At first, he was called Muggle; later, some people called him Jiang Yu; after that, more people called him KO1; and finally, everyone called him Alliance Leader! Jiang Yu traveled to the ultimate world and became a Muggle high school student. He was originally going to be invaded by demonic energy and become a demonized person, but was accidentally transformed into a half-demon saint by the system. From then on, demonic energy and combat power can be transformed. In order to free himself from the shackles, Jiang Yu concealed his identity and entered Guava High School, disturbing the original plot line and leading to a thrilling and even more magnificent time and space war! Forces from all sides have appeared one after another, and at this time, the Iron Spacetime Superpower Alliance itself cannot be protected. Let's see how Jiang Yu leads Golden Spacetime to break out of the siege! Many years later, Wang Dadong: Jiang Yu is indeed the strongest high school student I admit! Xia Tian: If it hadn't been for Jiang Yu at that time, I might never have been able to get out of that battlefield! Leader of Moxibustion Dance: The stability of time and space in the future will depend on Leader Jiang's contribution.
