I recommend the Reborn Genius Array Master. The male protagonist's surname was Dongfang, and he was in a wheelchair. His body was very weak, and his family was exterminated because he was seen as a sin. He continued to grow on the path of heaven-defying and possessed heaven-defying spells, arrays, and pills. The book was finished, and the ending was that the male lead's leg had recovered and was being repaired. I hope you like this fairy's recommendation. Muah ~😗
