Du Beishuang was not only the son of the Immortal Moon Palace Lord but also one of the ten Golden Core Stage True Disciples of the Fairy Moon Palace with a potential chance to inherit the position of Palace Lord in the future.
Being a True Disciple of the sect was no small matter, hardly anyone in the Fairy Moon Palace could surpass him in terms of status.
Not to mention Xu Mu, who was just an Outer Sect Elder. Even higher-ranking Inner Sect Elders would have to obey him.
