Resolve of a king

As for the remaining families; the Chu family had never hidden their ambitions for the throne. Even back then when the kingdom was just in its infDancy stage, the founder of their clan constantly squabbled with his ancestor for the throne. That spirit has been continuously passed down to the present generation. 

They have always eyed the throne. He couldn't do anything about them since they had an almost similar foundation. The Zhou royal family would end up with a pyrrhic victory if they decided to eliminate all sorts of cordiality with them. Other than that their family had the best weapon refiners and artifact makers within the kingdom. If a gold-grade artificer was to appear within the kingdom, it would be from their family. They were vital if they ever hoped to restore the Ebony Twilight Sanctuary Array.
