Chen Xi was startled and silently closed the document. He remembered that in original history, Mount Tai should have been occupied by Cao Cao, and then, because of Cao Cao's coveting Xuzhou, as well as a series of reasons including the Technique Alliance and the Shao Alliance, Tao Qian fought several battles with him, forming a deadly enmity. There was no possibility for Tao Qian to hand over Xuzhou to Cao Cao.
As for this life, Liu Bei resided in Mount Tai, and Cao Cao and Tao Qian simply didn't border each other, so those great battles from history couldn't take place. Tao Qian was basically just filling a role in the Technique Alliance until his health declined.
For the Tao Qian of this life, it didn't matter to him whether he handed Xuzhou over to Liu Bei or Cao Cao. The elderly and frail man had no grievance with either, and both Cao and Liu had shown their potential.
