This method of Foundation Establishment is no secret; the island natives all know it.
One only needs to find a Purple Crystal Salamander about to ascend to Tier Two, destroy its Divine Soul, and before its body dies, let a cultivator with Qi Cultivation perfection let its body parasitize in the Dantian, thus leveraging its body's liquefaction characteristic to assault Foundation Establishment.
The success rate of Foundation Establishment is greatly related to the timing of the Purple Crystal Salamander's ascension. If one parasitizes in the Dantian within a month before its ascension, the success rate reaches seventy percent, but the timing of the Purple Crystal Salamander's ascension is hard to judge. Once it begins to ascend and transform, it's already too late.
