Yang Shenlong departed peacefully.

The White Dragon of Shu Mountain was a newcomer, whereas the Azure Dragon of the Penglai Upper Sect had suppressed the sect's fortunes for thousands of years. Over these thousands of years, the Penglai disciples had developed many secret techniques from the Dragon Race's inheritance, such as Dragon Soul Guard and physical body transformation into a dragon.
As early as their first encounter, Chu Liang began to wonder how Yang Shenlong used this divine skill to partially transform his physical body into a dragon; he had never seen it before.
Later, he specifically asked Wang Xuanling about it.
However, Wang Xuanling knew little about it. After all, there were not many sects in the world closely related to the Dragon Race, and the path of Shu Mountain was also yet to be explored in this respect.
