Why does the sword idiot in Iron Sword say that he is a disciple of Yun Qi's real person Taiyi? Isn't that strange?

1. Maybe he was a disciple of Taiyi when he was not chased by Su Yang as a child. That experience should be quite refreshing, so I didn't forget it.

2. It may be the memory that Princess Ning Ke deliberately added to Tuo Yuwen when she changed him for the better, so that he can have a history or something and handle affairs conveniently. . .

It's purely personal speculation. If you are not satisfied, I will fly by myself. . . . .
