In the void above the Thunder Pool.
Ye Yun saw the mournful expression on Big Black Horse's face and smiled faintly.
"Isn't lightning your Innate Divine Ability? Given your current cultivation base, shouldn't you be able to refine it?" he asked aloud.
"I can't, Master. This is my first time hearing about the Rebirth Thunder. Its energy is too domineering; I can only refine one strand at a time. I estimate that I can't refine such a large piece of Rebirth Thunder. If I forcibly refine it, I fear my body would not be able to withstand it…" Big Black Horse complained.
He knew his impression in his Master's eyes had dropped this time.
But there was no way around it; his abilities were limited...
Even though he was a demon beast from the Eternal Realm and seemed powerful in front of the Three Saints of Accumulated Thunder Mountain, he was keenly aware of his own limitations.
This mysterious Rebirth Thunder was indeed something Big Black Horse could not refine.
