What is the reason why the master refused his nephew Yu Tianheng's request to go to Douro mainland to learn from him?

As we all know, Master Yu Xiaogang is Tang San's teacher. He left his family because of the variation of Wu soul, but the master's theory is well known all over the world. Some people regard it as a joke, but keep it in mind. However, the master's theory of witch soul has finally been successfully verified in the body, and it is a twin witch soul. Among them, Wu Soul of Lanyincao is a major in control department and has strong strength.

Tang San is the only disciple of Yu Xiaogang. This disciple not only realized the master's theory, but also became his pride. Yu Xiaogang's family once appeared in the animation. Yu Tianheng, the captain of the imperial fighting team, is the nephew of the master, but as soon as they met, Yu Tianheng wanted to worship Yu Xiaogang as a teacher and was declined. Why?

First of all, the master accepted Tang San as an apprentice because he had already judged his twin martial spirits when he met Tang San. Secondly, it is not easy to cultivate such a genius. Although Tang San is very talented, the master has worked hard on Tang San, which shows that it is not easy to train a person. The master basically put all his theory and energy into Tang San, so he has no extra ability to teach a person.

Another point is that the master has made some achievements in Tang San, and the previous theory has been basically realized in Tang San, so there is no need to accept apprentices, and Yu Tianheng, who was born in the blue Tyrannosaurus family, has his own family to help him practice. Although Yu Xiaogang is still Yu Tianheng's uncle, he has left the family, so accepting Yu Tianheng as an apprentice is bound to be confused with the family of blue Tyrannosaurus Rex, which also violates Yu Xiaogang's original intention of leaving the family, which is why Yu Xiaogang doesn't want to accept it.

Finally, after meeting Master, Yu Tianheng said, "If you fight one-on-one, his blue-electric overlord dragon soul will definitely defeat Tang San." This sentence is full of conceit and arrogance, and lacks composure. You know, if you want to be stronger, your mentality is also very important. A person's mind determines his future cultivation realm. On the other hand, Tang San did not show pride and conceit at any time, which even Yu Tianheng could not understand.

The above is just my personal opinion.
