The heir did this, because he could not handle the Prince from the North Qi Land, and got really angry, but he just could not do anything about the Prince and he was even forced to talk with others by lowering his own status. After all, the magical monsters of the North Qi Land were such a great thing that he wanted to get them for himself for private reasons.
Although he had told Xie Yan about the plan, he was still really annoyed. That was why he wanted to go to Lady Chaoyan to vent his anger. The heir was someone who bullied the weak and feared the strong.
Xie Yan would have dropped it in the past, but now he was the heir, and what he was doing did not cater to his social status at the moment. Also, wasn't he worried that Gu Chaoyan would spill the secret to the public?
If that was the case, there would be a lot for the heir to deal with by that time.
Xie Yan sighed and shook his head. He went back to get ready for his own business.
