Hellwither Nineruins was refined from the blood, flesh and fat of a true Immortal. By congealing the deep rancor felt by a true Immortal in the moments before death, a powerful curse was formed. As long as it didn't touch any land, its power was ordinary. However, once it touched the land, the power of the curse would be unleashed on all living things that were born in that land.
It only had one fatal flaw, or perhaps it would be more accurate to say a weakness. While it was true that it used the refined rancor of a true Immortal's flesh and blood to curse the land, the curse couldn't be sustained for very long. At the most, it would last for three months before the land naturally purified itself!
Unfortunately, three months was enough time for all of the cultivators in the Southern Domain to be completely withered up and weakened to the point of death. For those who didn't die, their cultivation bases would be significantly reduced.
