There are records in history books: Those who do not grow old are immortals; those who practice the Immortal Secret of Immortality are immortals who do not age.
Another secretary: Forty years ago, a mysterious organization suddenly appeared in the martial arts world called "Netherworld". Although there were not many of them, they all possessed unique skills, thus setting off a devastating bloody storm in the martial arts world. Some people say that the owner of "Netherworld" comes from hell. As long as his eyes look at you, your soul will be taken away; he only needs to wave his hand, and countless evil ghosts will crawl out of hell and trample the rivers.
