It happened so suddenly that Meng Hao could only watch with wide eyes as the two Nirvana Fruits shot toward the pill furnace. The one that took the lead was the one which Meng Hao had spent so many spirit stones on, and was on the verge of already being completely restored.
Meng Hao's mind filled with roaring as he suddenly realized that the seven-colored liquid must have the same function as Spirit Elixir. It wasn't meant to be consumed, it was meant to be used to restore Nirvana Fruits.
A Yin aura of death could be sensed within the liquid, an aura that represented the lack of life and destruction. The Nirvana Fruits had been withered for eons, and were essentially dead. However, it seemed that when they touched the seven-colored liquid, the Yin death aura would reach a pinnacle in which life force suddenly appeared!
That life force represented the restoration of the Nirvana Fruits.
