Before coming here... Xin Yun had not considered negotiating at all, but now... Xin Yun was moved, and very much so. Of course, this didn't mean that Xin Yun had forgiven the Kashi Family. In fact, once the Kashi Family clashed with the Sky-opening Sect, it was destined that only one side could remain in this world. Xin Yun's interest was not truly in negotiating but in another idea.
Relying on outsiders to eliminate an opponent was a move of desperation. Now that the other party was willing to talk, it couldn't be better. Just give Xin Yun a little more time, let the Silver plan take off, let the Sky-opening Axe unseal further levels, let the strength of Xin Yun and others grow stronger. By then, who would need the help of others? With just the strength of the Sky-opening Sect alone, they could bring about the collapse of the Kashi Family. This was Xin Yun's ultimate goal!
