Traditional martial arts.
Chai Zuoben was the adopted son of the Chai family. He was young, promising, and highly skilled in martial arts. He was from a prominent family because of his reputation as Chongyi Gong of the Chai family. However, Yue Fei was killed and the revelation of his life made him lose confidence in the world. He was forced to break away from the Chai family with his arms broken, becoming a "waste" with no power, no family, no martial arts, no love from Song Dynasty, and no peace of mind from gold. But is he really a "waste"? No rights? Then I will use my peerless martial arts to fight against power! Powerless? Then I will rebuild the martial arts power! Homeless? Then I will go on a killing spree without caring about my family ties! Don't you love Song Di? I can't wait to see you being such a coward and a sycophant! Not accepting gold land? Who in the world can stop me from going or staying! Grab the little princess of the Kingdom of Jin, put aside your prejudices, and travel around the world. A broken knife, one arm, and half a face, but he has become a legend!
