Locke's Star's Kings were essentially famous individuals in the Great Mercenary College of Locke. In the eyes of the people from Locke, other than those who hailed from the strong empires like Aslan, the rest were no more than drifting clouds.
They possessed a complete and systematic form of training and were able to develop invincible individuals and small squads.
There was nothing one from Locke could not do nor did not know,
A wealthy patron had paid a large sum for these individuals to come to Earth to trounce Skeleton.
It was a simple job for Zha Rang, and he would earn a tidy sum upon completing it. Of course, the patron also had their own request. They had to suppress and utterly decimate their opponents with what they were best at.
This was what the people of Locke were good at and something they could accomplish.
