In reality, the Yang Family's so-called ceremony should be a type of Nuo ritual passed down through generations.
In ancient times, the number of Cultivators was very, very small. Not to mention immortal arts, the ancient people had barely even seen Immortals.
But plagues had existed since the creation of heaven and earth, and monsters and specters would not pity ordinary people.
Death and loss, sorrow and pain, made people want to do something, even if they didn't know if it would work.
Thus, to expel ghosts and drive away plagues, there was this Nuo ritual to pray for peace, hoping that the 'Nuo Gods' of their imagination could dispel evil spirits and protect them.
With the passage of time, such Nuo rituals have almost disappeared today.
It seems only the Yang Family still adheres to this very ancient tradition.
The Yang Family's Nuo mask is probably also an ancient artifact passed down from a very long time ago.
