The Legend of Red Shadow in Classic of Mountains and Seas

He has a few very good buddies, parents who get along very well with him, and three very fond of his female classmates. He is already a billionaire when he was in junior high school. He has his own listed company, talks about his own novels, rushes logistics, plays billiards, and writes calligraphy. He is simply a wizard. This novel and its characters are purely fictitious.
