Looking for a Prince of Tennis Novel. The Protagonist Is Chinese, Surnamed Luo, and Plays for Rikkai. His Tennis Style Is the Emperor's.

The main reason is that there is a scene of pretending to be a 13-year-old that directly touched my heart. When Nioh Phantom faces a powerful enemy without being able to phantom Yukimura, he can only choose the all-rounder Phantom, and the protagonist is an all-rounder. And because the protagonist of Nioh Phantom is present throughout the game, pretending to be 13 is very successful. I remember that the protagonist's name seems to be Luo Shen, but I checked that Luo Shen is in Fudong Peak, and there seems to be something wrong. If all book friends see this, please use your little hands to make a fortune and leave precious answers. Thank you ヽ(^0^)?
