The 'Nether Flower' and the 'True Yang Flower' were two of the rarest herbs in the Immortal World.
They were ranked 9th and 5th in the list of the most precious herbs. The 'Nether Flower' was used mostly in poisons with Yin attribute, and by cultivators of Yin Qi.

The reasons were simple. The 'Yang True Flower' could burn the impurities in their bodies, by igniting their Yang Qi and increase their cultivation without any side effect.
That was why every time such a flower was brought to the scene people would prepare big chests of pills, relics, weapons, treasures, and God-stones to buy it.
But there was also another reason why he asked for such a herb. The truth was that Earth had surprised him with its resources.
