Chu Zhongyuan was merely the son of a local merchant family. Though they had some money, the Chu Family could not even be considered an ancient family, at most they were just nouveau riche!
As such, Chu Zhongyuan naturally never had any contact with the circle of Huaxia's ancient martial arts. The only reason he later came to know of their existence was due to Yan Haonan, the leader of the Tiangou Gang, who inadvertently revealed it to him.
However, Yan Haonan was also just a martial artist who had barely entered the threshold of the Houtian First Layer. Even so, with his own strength, he managed to establish his territory and became the leader of Zhi'an City's underground society.
