The Crown Prince had personally gone to Xiahou Mansion to acknowledge him as his master back then, but Xiahou Tang rejected him.
The Crown Prince was furious that he was brushed away.
After returning to the Crown Prince's Mansion, the more he thought about it, the more embarrassed he felt. He was about to get someone to teach Xiahou Tang a lesson.
Unexpectedly, Xiahou Tang came personally that night and openly accepted him as his disciple.
The Crown Prince was not the only one who was puzzled. Even the Eldest Prince was puzzled.
The Crown Prince initially thought that Xiahou Tang had suddenly gone back on his word and accepted him as his disciple to monitor him on behalf of the Eldest Prince.
However, he discovered by chance that the Eldest Prince was rejected when he personally went to Xiahou Mansion to find Xiahou Tang.
