A Su is a student at the Prophet Academy and also a famously notorious troublemaker in Bright Pearl City.
As a Skeleton, A Su staunchly believes that "steel is the force of civilizational progress" and holds disdain for others who choose to continue using bones to make bone mechanisms.
If not for the fact that Bright Pearl City is located at the border between the Skeletons and the Jiao Race, it's practically impossible for any Burrowing Insect to settle here.
Anyone familiar with A Su wouldn't doubt that this guy would definitely run off to the Burrowing Insects to learn from them, having them teach more knowledge and technology from the Burrowing Insect Civilization.
Even so, A Su has built a laboratory full of Burrowing Insect style in his own tomb.
