At this moment, Xing Kai was indeed thinking of killing him. After a series of defeat, he asked himself whether or not he could just let it go.
During the Peach Banquet, he was overshadowed by Ye Futian twice, which had affected his Heart for Law.
He felt Ye Futian had become the barrier on the way of his cultivation. It would be hard to enter the Unblemished Plane because of him. For Xing Kai, it was absolutely unacceptable.
Anyone who hindered his cultivation was supposed to vanish—to be out of his sight.
Thus, Ye Futian should be wiped out, and if possible, Xing Kai should kill him in person.
In this way, Xing Kai could prove his Heart for Law.
Not to mention the grudges Xing Kai had already had with Ye Futian. Ye Futian should be killed. Otherwise, he would become a scourge for the Ancient Imperial City.
