After closing his eyes, Athan first checked the situation of the black and white orbs. He remembered that only the white orb absorbed the life energy, and the black orb didn't.
Looking at them with his soul sense, Athan thought, ' First, They are the part of my body. Second, Both of them readily absorbed the primal energy, and that's why my body recovered quickly. But...I tried to let both orbs absorb the life energy, but only the white orb absorbed the life energy and then fundamentally provided it to my body so that it could recover quickly. On the other hand, The black orb didn't absorb the life energy. '
Athan wanted to experiment with this again, so he brought out Primal essence from the source dimension and controlled the black and white orbs so that they would absorb this primal essence.
And indeed...Both of them absorbed the primal essence, and his body started to get stronger.
