An Ordinary Ball, but in Lihai University

Oda Hashun was a professional tennis player in his previous life. But everyone else is playing ordinary tennis. Only Bo Xun can hit the ball to the ground with one ball/his body emits a dazzling light when he uses his special move/destroy the entire tennis court with one special move. Therefore, in order to cater to the level of those around him, Bo Xun could only practice "normal one ball" hard, and since then he has sealed all his ultimate moves. After reaching the pinnacle of professional tennis, due to a plane crash, this talented tennis player went straight through time. In this world, Bo Xun met the same parents and had the same name. He inquired about where the strongest tennis school was and immediately transferred to Tatekai University in Kanagawa. And habitually... Used "ordinary one ball". ——At the beginning—— Onlookers: Why doesn't this guy have a big move? You're just playing tennis in an ordinary way, without Kuangba's cool and cool second move, who's watching you play tennis! Isn't this just the ordinary level of picking up a random passerby? How did he get into Rikkai University? ——Soon after—— As we all know, Oda Hashun has a poisonous mouth and an arrogant personality, and his whole person exudes an aura that needs to be beaten. Moreover, he is never merciless when playing with others and will only kill his opponents! But! Yes! Playing tennis with him will not cause your five senses to be destroyed, break your bones, vomit blood, or put your life in any danger! There won't be any damage to the tennis courts either! ! Everyone: Although this guy deserves a beating, his style of play is so friendly and accessible to all ages! Playing tennis with him is really just playing tennis! It turns out that simply playing tennis can be so happy! This guy is so powerful, he must have some great tennis moves, but he just doesn't use them! ... I understand, he must be to let us see the essence of tennis clearly and help us find our original intention of playing tennis! It turns out that he insisted on playing ordinary tennis all because of us! ! ※Small theater※ In order to commemorate his parents and himself in his previous life, Bo Xun secretly built a monument for them. He would visit them regularly and report on his current situation in front of the monument. Everyone in the tennis club who secretly followed Xinghao Shun: Minister Maori: Did you see that he showed such a gentle expression? Kirihara: Have seniors ever shown this kind of expression to us? Yagyu: ... He just laughs and taunts. Kuwahara: So whose tomb is that? He must be a very important person, right? Liu: Once, Bo Xun mentioned his "former teammates" and "but they are no longer here." Everyone else:……… Everyone: Got it. ——Why doesn't Bo Xun show such an expression to us, never remember our names, and hide his strength from showing us his ultimate move... It turns out that it's all because we didn't get into his heart! He actually still has Bai Yueguang from another team in his heart! ! ———————— Instructions for consumption: ① I wanted to play with the name, so I picked the male protagonist. ② There is Sanada, Tokugawa and Ryoma in Yukimura, so of course there must be Oda as well. ③Li Hai is the strongest, and the male protagonist is the strongest Intention: If you don't accumulate small steps, you can't reach a thousand miles.
