I Only Have One Sword!

My name is Xiaosa, and I am also very chic Xiaosa. When he first came in, he was left on the next screen covered in blood because he was a waste material. After more than ten years, I am still useless. Children of the same age either awakened their spiritual roots or awakened their talents. Except for me, they were just as ordinary as ever. Until one day, Chochai was saved by a half-broken sword, and then taught me a move. It only taught me one trick!
