Yu Xishen still remembered that day like it was yesterday. He was playing with his brother when suddenly, their enemies attacked. His parents were killed, his brother was killed and his beautiful house was burned down. Miraculously, somehow he survived. However, in the fire, half of his face got burned.
At that time, he was the only one who was left alone. Everything and everyone that was related to him was gone. Later, he learned a harsh lesson that only by becoming evil can you survive in this evil world. He entered an orphanage and then, he worked hard, made himself what he was today. He never treated his face because this was the reminder of his mission, his revenge, and his motive.
He was living only to kill those people.
