Introduction to Yang Zhi Selling Knives: It’s a pity that a hero is in trouble, but his sword is also covered in dust. The "green-faced beast" Yang Zhibing was loyal to his ancestors and had a desire to repay the favor. He originally wanted to restore the prestige of the Yang family. However, there was no way to serve the country, and he ended up living in the streets, selling his ancestral sword for three meals a day. The hero has no choice but to suffer from shortness of breath, but he is bullied by the gangsters in the market. How can he endure the sadness and the fire of ignorance again and again. The sword was unsheathed and he slashed two cows angrily, showing his true colors as a hero at the end of the road.
