"The hero who brought it down, was it Yin Jiu You?" she said sarcastically.
"Over ten thousand years ago, that plague implicated a vast area. The Plague Demon's actions were truly unsightly, with an enormous amount of mortals dying in the plague, endangering the rule of the Immortal Sects, forcing the large Sects in the Southern Continent to issue a decree to attack the Plague Demon. Yin Jiu You also secretly took action from within one of those Sects."
"At that time, the advantage of longevity and rich experiences came into play; he actually knew that the vital point of the Plague Demon was not on its body, but stored in what's called a 'Life Box.' This item is its weakness and where its True Body resides, and can be separated and hidden from the body. Only by shattering the Life Box will the Plague Demon truly fall."
