Reincarnated as a Top Student in the Magic Academy

[No heroine+slow heat+a lost campus+adventure] Lu Zhaoye was reborn, thinking that since he had memories of his previous life, he would definitely make a fortune in this life. As a result, as I grew older, I met two children who were following me. When I went to play at their house, I saw several people flying in the sky. Lu Zhaoye:? Isn't this wrong? Only then did he discover that this was a parallel world where magic could be used, and he also had the qualifications to become a magician. (The writing is very shitty and I don't recommend reading it. I am purely basing it on myself)
