Why did Yan Yan seal Fu Xiqin in Sansheng Shishan?

In to the sky kingdom, he is the most willful and natural little fairy, who can do whatever she wants and ignore anything. He lived in seclusion in Taolin for hundreds of thousands of years and never cared about the world, but in the four seas and eight famine, no one dared to ignore his existence casually, and even the present heavenly army was afraid of him. He is very loose, probably because of this, so many people don't remember him. He is also a soldier who fought side by side with his father, and his ability is very strong.

He is the first old phoenix since the beginning of time, but he belongs to the constitution of half magic and half fairy. Father God brought him up with Mo Yuan since he was a child. Although he is not so bad compared with Mo Yuan, he has an instrument called Fuxiqin, with which he is invincible. But in the TV series we watched, he closed the piano. Since the piano is so powerful, why did he do it?

In fact, because he belongs to a semi-magical and semi-divine constitution, it means that he may become a god and a demon at any time. The magic in his body has been suppressed very well, but if he uses this Fuxiqin frequently, it is easy to inspire a kind of magic in his body. If it takes a long time, he may become a demon. As far as his strength is concerned, if he becomes a demon, it will be more difficult to deal with than Yi Cang.

If he really becomes a demon, after the death of Father God, there may be no second person who can suppress his magic, so in order to prevent a big mistake, let him seal the piano. After sealing Fu Xiqin, he lived a very comfortable and happy life. He drinks, fishes and hangs out with Bai Zhen every day. I don't know how happy I am. He is an old phoenix with no ambition and just wants to live as he pleases.
