"A few days ago ehe returned to the Heaven Realm, so you might need to go there to find her," the Ancient Night King replied.
Thinking about coming there again, Ciel rolled his eyes.
First there he made Yelina his wife, then Rebecca. If he came again and this time made the Goddess of Heaven his wife, Ciel was worried that there would be a lot of anger. The Heaven King would surely be furious, perhaps even the Heaven Ancestor.
The latter had done nothing about his relationship with Rebecca. It was said that he was open-minded, not even forbidding women in his clan from choosing their own men.
He also did not interfere with the relationship between Ciel and Yelina, his granddaughter. Only the Heaven King showed displeasure.
However, Ciel wasn't sure that he would still think that way when his only daughter would also become Ciel's wife.
The problem was that it meant his daughter and granddaughter would be related to the same man.
