Before this, Princess Glaze asked Qin Wentian what his relationship with Qing`er was and Qin Wentian replied that she would know soon after.
Now, Qin Wentian said that Qing`er actually got her royal father, the Evergreen Immortal Emperor to help by asking the Eastern Sage Immortal Emperor to accept Qin Wentian as a disciple. One could very well imagine how close the relationship between this man and Qing`er must be.
Back when the Evergreen Immortal Emperor fought for his empire, he sent the baby Qing`er to a particle world. Princess Glaze was naturally aware of this point and she could easily guess that the two of them must have met in the particle world and there was also an extraordinary relationship which developed between them, they might even be lovers.
