The energy required for the eleventh fruit had increased significantly compared to before. Normally, it should have required energy equivalent to a soul beast of over sixty million years, but the actual amount might exceed one hundred million years. If Hundred-Thousand-Year Soul Beasts were used to fill it, even a thousand of them might not be enough to fill half of it.
This energy could not simply be added together; there was a conversion involved. Just as one-tenth of a million-year soul beast's energy was by no means comparable to the energy of a Hundred-Thousand-Year Soul Beast.
This energy exceeding one hundred million years might require several thousand, or even tens of thousands, of Hundred-Thousand-Year Soul Beasts to satisfy. Such an enormous amount of power was terrifyingly exaggerated; even a god-level heavenly tribulation could not satisfy it.
After striking for over an hour, the heavenly tribulation stopped. It had been drained dry. Under normal circumstances, it should have ended within a dozen or so minutes after beginning, but Chen An had the Mountain Dragon King Undead Puppet control the heavenly tribulation and keep it descending until the Heavenly Tribulation Lightning stored within this plane had nearly been exhausted.
This plane would find it difficult to form another heavenly tribulation in the near future. Even if soul beasts underwent tribulation at this time, they would not need the Thunder Hell Vine's help to pass through unscathed, because there was no lightning left to strike them.
Even after draining all the lightning in an entire plane, Chen An had only filled his eleventh fruit to a little over eighty percent. There was still some left to fill, forcing him to think of another solution.
The Thunder Hell Vine could not provide him with thunder energy. What he needed to absorb was thunder
