Zhao Hai and Zheng Li were both stunned when they heard the sound of fighting. Although Zhao Hai was not from the world of self-cultivation, he had stayed there for a period of time. In the world of self-cultivation, it was rare for people to fight in the cities and the residential areas outside the cities. This was because these cities were controlled by some sects. If you fought in the cities, it would be equivalent to destroying that sect's property. Wu Lun and his sect would not agree to it.
When Zhao Hai was living in the sea Mountain City, Helian da came to seek revenge. The two of them had agreed to meet in a small mountain outside the city and fought. They didn't fight in the residential area inside or outside the city, because if they did, the sea Mountain sect wouldn't let them off even if they were weak.
