The plot of this animation may be because the screenwriter didn't think too well. It seems that animation is to finish the story of the novel in three volumes at once. The first volume of the novel is the story of Seldi looking for a head, the second volume is the story of the slasher, and the third volume is the story of the yellow turban insurrectionary thief. In the novel, I didn't know what happened between Zhang and Seldi until the whole incident happened (the images of Zhang and Seldi were also admitted by themselves at the beginning). At that time, it was already clear that Seldi also gave up the regime change, and Bojiang, whose head was captured, hid in Linya. Later, everyone lived a normal campus life. Volume 1: Teijin is the founder of Dallas and is now the supreme leader. Volume 2: There is a real demon sword fairy Song hidden in apricot, which is the actual controller of the demon sword Sect. Volume III: Cheng Zheng returns to the leader of the yellow turban insurrectionary thief because of hacking. These three people are the so-called Ikebukuro Big Three, but they don't know each other.
