[Comprehensive] I Am Super Ordinary as a Saiyan

My name is Sun Shenyu. I am an ordinary high school student with low-profile grades, low-profile appearance, and very low-key strength and a super-ordinary righteous Saiyan. During an operation to save the earth, I accidentally fell into the vortex of parallel dimensions and came to a parallel world. As a result, as soon as I came out, I met a black hat who was slaying a dragon with a building. Our Sun family has always had a very good relationship with the Shenlong clan, so I knocked out the little black hat with one punch. Later, I was inexplicably wanted by the local forces. I didn't know why, so I stabbed their lair in a low-key manner and rescued the little blond girl who was imprisoned by the evil boss. Later, I saved a bandaged young man who accidentally drowned. In order to repay me, he said that he would collect the Dragon Balls with me and then make a wish and send me home. Intention: None
