Chai Wei was a famous general with great martial arts skills in his previous life. Three hundred years later, he was reborn as a loser. The first time he went out, he was chased by vicious dogs all over the mountains and plains. He had no choice but to sneak into the market and make a living by making jokes. One day, for two taels of silver, he just hired a fairy-like man to be his apprentice. From then on, his life reached the peak of cheating.
