Legend has it that no one can defeat the Underworld Butterfly Cult.
Legend has it that the leader of the Mingdie Cult once again rescued an immortal who accidentally fell into the world during a hunt. The immortal repaid him by giving him a martial arts secret book - Die Sui Sui.
But there are rumors that those who practice Die Sha must rely on men's masculinity to mend it. At the end of each month, men must perform boudoir rituals in order to break through and become immortals.
No one knows whether the leader of the Underworld Butterfly Sect practices this martial art, no one knows where this secret book is stored, and no one knows whether he can truly practice it and become an immortal.
What we know is that the leader of the Underworld Die Cult gave birth to a child in his second year. It is said that when he was born, his face was covered by a blue butterfly. Some people rumored that the leader of the Underworld Die Cult really practiced Dieshui and gave birth to the child through a man. He was a monster.
Since then, the Underworld Sect has become a legend, like an illusory existence, like a mystery, and more like an omnipresent myth...
