The Devil Rises from the Abyss of Extreme Life

Is the legacy of the disaster that has not been recorded in history the magic of immortality? Some people have fallen into the abyss of pain in order to obtain it. They only know that it has the effect of immortality but do not know the pain it brings. Thousands of years have passed. Is there any successor to this ancient secret technique? How many more people are willing to risk their lives to take it? But I don't know how many pairs of eyes of desire are watching behind this.
