Let's talk about the ending of Han Yun first. It is the egg that Chaoyun has control over, but he gave it to his younger brother and slept by himself, which is in line with the ending of Hanyun.
On the other hand, looking at the ending of Yao in the cloud, even if Muyun finally defeated his brother and went to the mountain and sea to summon Huangfu Muyun, the gods facing the cloud were still asleep. In the end, when Xia Rou returned to Xuanyuan Street with Xuanyuan sword, he could only recover the firm but gentle knowledge of Chaoyun.
PS: White King's true identity should be clear when Xuanyuanjian 6 is released from DLC or prequel. If LZ played Xuanyuan Sword 6, he should know what I'm talking about.
