章節 1315: Chapter 519 River Duel_2

Even the Eight Yuan Heavy Water has never been mastered by anyone.

Several of the Dragon Ancestors within the clan have barely managed to cultivate the Seven Yuan Heavy Water, but beyond that, there were almost no paths left for further cultivation.

The reason is quite simple.

This method of cultivating Absorbing Heavy Water requires continuously absorbing external water to enhance one's own gravity and Absorbing Field.

In the beginning, the cultivation of this technique was relatively easy and didn't consume much water.

However, in the later stages, even just cultivating the Six Yuan Heavy Water would require at least ten billion times the water of a Single Yuan Heavy Water, that is, a hundred billion Jiuchuan water.

Perhaps this doesn't mean much to everyone; to give an example from Lu Yuan's previous life on the Blue Planet, emptying the entire Indian Ocean would still not be enough to cultivate Six Yuan Heavy Water.
