Yeah, those negotiations were totally pointless from an operational point of view. They only served Tian Cheng to see which ones of the clans are interested in raiding the infected, which ones are planning to attack other humans. He already destroyed the head of the latter one. But otherwise the Young Miss as well shouldn't waste time on the negotiations. Since the group attacking a nest first will also attract the attention of nearby nests, she only needs to wait until Tian Cheng lauching his attack. A moment later she can attack a nearby nest, which would have lost some of its guardians that headed off to stop Tian Cheng. So, what need is there for negotiations?
