His mother was responsible for the blood-flaming poison in Su Yu's body. She fed him the poison bit by bit after he was born. The poison had followed him for a long time. Yun Feng was from the Yun family—a family that had passed on the knowledge of medicine for thousands of years. Yun Feng had the talent to treat poison since he was young.
Su Yu's lady master was from the Yun family. She helped to take care of him and suppressed the poison when Su Yu was under her training. After all, Su Yu was from the Nanyao Nation. He could not stay with her for long. Thus, she sent her nephew, Yun Feng, to take care of Su Yu. Yun Feng had been by Su Yu's side for 13 years. He knew the poison better than anyone else and how difficult it was to expel from his body.
He had tried his best and never thought that things would take a new turn.
