Ye Nishang did not appear to be one that was thick-headed. She must be quite smart to be able to trap Lu Zhengyang and so many Earth Immortal Realm warriors.
Lu Li had stepped into many traps over the years. Last time, at the Ocean Land of the East, he was almost screwed. Besides, his sister was a great strategist. Influenced by what he constantly saw and heard, he knew a thing or two about setting traps.
As he continued to butcher the Feather Race warriors, he kept checking the surroundings with psychic power. He tried to think and figure out what Ye Nishang would do to him.
Without a question!
He and the Dragon Demon could defeat any Feather Race warriors. None of the Feather Race would be more powerful than him or the Dragon Demon. Otherwise, Lu Zhengyang and the other patriarchs would have been killed, not trapped.
