Why can't I understand episodes twenty-two to twenty-three of Jade Dynasty? Tianya Online

I really don't understand what happened in the 22nd to 23rd episodes. In the beginning, it was written that Tian Buyi and Dao Xuan went missing. Later on, when Zhou Yixian bumped into them, Tian Buyi died trying to save Zhou Yixian and the other two. The Scarlet Flame Sword was also broken. Su Ru went down the mountain to look for them. She happened to meet Zhou Yixian, Xiao Huan, and the other two. She saved Xiao Huan. Later, Zhou Yixian told her about Tian Buyi's whereabouts. She went to the memorial hall and found Tian Buyi's grave and broken sword fragments. She also found Dao Xuan. In the exchange of blows with Dao Xuan, he cut into the next chapter. Suddenly, Lu Xueqi went to the mortuary, and Little White was there. Then, Tian Buyi didn't die and was still in the coffin. Zhou Yixian and the other two were there, and there was also a lich. After that, Lu Xueqi 'rescued' Tian Buyi. Later, Zhang Xiaofan (Gui Li) chased the mysterious person (Dao Xuan) to the mortuary. The three of them fought and Tian Buyi died. Gui Li recognized his ancestors and returned to the clan. Tian Buyi hurt Gui Li. Xue Qi killed Tian Buyi. Gui Li climbed the Great Bamboo Peak. Su Ru did not leave the mountain. Moreover, the Ghost King Sect was in Hu Qi Mountain. Shouldn't they have already gone to the Wilderness? Li Xun brought people to "clean up" the Ghost King and Mr. Ghost, and then they were wiped out... I don't understand what's going on. Are you writing a game script or a novel? I don't think you should write two lines in a novel.
