Why did Yang Dingtian choose Xie Xun instead of Yang Xiao as his successor?

In my personal opinion, Yang Dingtian chose Xie Xun as the heir in "Eternal Dragon Slayer" because Xie Xun was more loyal to Zoroastrianism than Yang Xiao; And regardless of martial arts or ingenuity, Xie Xun and Yang Xiao are equal. Xie Xun was chosen instead of Yang Xiao because Xie Xun paid more attention to feelings and justice, and would never betray Zoroastrianism and friends. Moreover, at that time, when the four Patriarchs, Sanfen and other masters were present, only Xie Xun was generally expected.

At the peak of Zoroastrianism, due to the unexplained disappearance of its founder, Yang Dingtian, Zoroastrianism was later torn apart by leaderlessness. The five scattered people don't like each other and won't listen to other people's orders, and the rest of the French kings have become carefree people; The purple dragon king has already left Zoroastrianism, and the white-browed eagle king left Zoroastrianism to establish the Skyhawk. As for the Golden Lion King and the Blue Winged Bat King, they both became stragglers.

Although Yang Ding, the leader at that time, prepared a suicide note before he was born, he appointed Xie Xun as the temporary leader; However, because no one has found his body for many years, this legacy has never been fulfilled. After many years, I found that Yang Dingtian's decision was right. Zoroastrianism may gradually disappear if Yang Xiao takes over as leader. It turns out that the Golden Lion King is more reliable.

In those years when Yang Dingtian disappeared, because Zoroastrianism was leaderless, Yang Xiao stayed in Guangmingdingtan as the generation leader. Because he did things casually and didn't like to discuss with others, he finally got five people to run away and broke up with Zoroastrianism. In recent years, he himself has offended the major sects of Wulin many times because of personal grievances, which led to Guangmingding being besieged by six sects.

On the other hand, Xie Xun's performance in recent years, although living in the Central Plains for many years, is still as brother and sister as the sworn Golden Orchid Purple Shirt Dragon King, and has repeatedly laid down his life to save him. Finally, after hearing that Zhang Wuji was the founder of Zoroastrianism, he immediately went down to salute; All these show that if Xie Xun becomes a leader, he will be more reliable than Yang Xiao, which shows that Yang Dingtian's vision of employing people is still correct.
