Actually, when Ye Yinzhu led the Undying Demon Dragon Knights back, he saw that only Master of the Dark Tower, Slone, was commanding from the air, not two or three Tower Masters from Faran's Seventh Tower as he had imagined. His heart had already settled.
Having visited Faran in person and being familiar with the strength of Qin City, if there had been more than three Tower Masters from Faran, the outcome of this war would have been up in the air.
But with only Slone present, Ye Yinzhu was confident of victory. Slone wanted to retreat; it was no longer a matter of him sparing Qin City, but whether Zither Emperor, Ye Yinzhu, would spare him.
Ye Yinzhu's hatred for Slone ran deep. If not for him, how would his teacher Phil Jackson have died? If not for him, how would Sura have barely escaped death, and how would his own vision and taste have disappeared? The mastermind behind all this suffering was none other than the despicable Master of the Dark Tower before him.
