Si Teng and Bai Ying were two split characters from the same person. Si Teng represented the rational, kind, and intelligent side, while Bai Ying represented the emotional, greedy, and fierce side. There was a complicated relationship between them. Si Teng gave Bai Ying half of his strength in the play, hoping to defeat her. However, Bai Ying's performance after her resurrection was beyond Si Teng's expectations. She displayed powerful magic power. As for why they looked different and why Bai Ying could host someone else, there was no mention of it in the current information.
