Lou Zhuge saw the interaction between that unknown young man and his brother Lou Wuye and felt disgusted. He couldn't believe that his biological brother was involved with this aborigine from the Diamond Cosmos. How can he mix their bloodline with them? In his eyes, the Diamond Cosmos is just like those other cosmos their Dark Cosmos Lord had destroyed after they finished absorbing all their resources. It's just a disposable cosmos that can be destroyed anytime. If not for its guardian being unexpectedly powerful, this diamond cosmos would have most likely been theirs already. That's why he looks down on the aborigines that live in the diamond cosmos.
Seeing Lou Wuye getting so lovey-dovey with Yun Ming just simply makes him sick and he couldn't tolerate looking at such a loving scene.
