Killing Lu Ye was to eliminate a hidden danger, getting his hands on the Dragon Throne would provide him the capital to protect himself; otherwise, once the news of Lu Ye's death by his hands spread, he wouldn't be able to get past the obstacle of the Three Great Overlord Sects.
The prestige of the Dragon Throne had already deeply ingrained itself in people's hearts; that earth-shattering strike was a height unattainable in a lifetime of cultivation for cultivators in the Soaring Dragon World.
Thus, even if the peril of the Dragon Throne was broadcast along with the news of Lu Ye's severe injuries, it still couldn't stop some people's covetous views.
Xiong Tieshan was one such case, and so was this batch of cultivators he tangled with.
With the Dragon Throne in hand, it's not to say they could command the Three Great Overlord Sects, but at least within the expanse of the Soaring Dragon World, it was unlikely again that anyone would dare threaten their safety.
