Is Xu Xian, the legend of the new White Snake, a Buddha or an immortal?

Finally, he became immortal, but I could see that he was not happy and didn't smile at all. After he became an immortal, he must abide by the rules of heaven and never see any other relatives again. But after all, he became a fairy, and it is necessary to know how many mortals keep practicing and even possess themselves.

Reason:

First of all, when Xu Xian was a little shepherd boy before X, he saved the white snake from the old snake catcher because of his heartache. He didn't want the white snake to become a spirit snake, and promised to save the little shepherd boy's life in the future, which was related to demon fairy.

The second is that Xu Xian is a good man in the 10 century. He always puts kindness first for everyone. After he married Mrs. White Snake, he opened a drugstore and helped the world. He has held many free clinics and accumulated many good results. Good things are rewarded.

Third, because of this feud, Xu Xian fled into an empty net and devoted himself to practice for 20 years, so that he who sees through the world of mortals had an epiphany and began to think that Fahai was a virtuous monk. At first, he also saw that Xu Xian was predestined friends with Buddhism. With these factors, Xu Xian could naturally soar to immortality. Of course, this is the need of the plot, and there will always be a happy ending in the end. Both Xu Xian and Bai Niangzi are flying immortals, which really makes people feel complete.
