What surprised Ye Feng, however, was that this energy was not chakra, but extremely pure origin force:
Could the essence of "Kāma" be origin force in its most primal form?
Ye Feng was not certain, but he did not stop it. Instead, he carefully sensed the energy.
A long while later, delight appeared on Ye Feng's face:
"This power really is origin force. In this tiny amount of time, it's brought my fire origin to perfection, and my earth and metal origins have made considerable progress too. Not only that, this energy also contains an extremely powerful yin-yang origin."
Seeing Ye Feng's expression, Orochimaru knew something good had happened, so he asked:
"Have you discovered something, Ye Feng?"
At those words, Ye Feng came out of his delighted surprise and spoke without concealing anything:
"Haha, this mark is actually a great source of nourishment. But only someone in the golden core realm can resist this mark, or even absorb it!"
Orochimaru could not help looking envious at those words. Still, his most urgent task now was to purify his soul, or he would not even be able to enter the golden core realm.
While speaking, Ye Feng was also watching Orochimaru's expression, so he quickly added:
"Once I advance another step, I'll be able to cross the void and enter worlds beyond the Shinobi World. Since we've encountered several members of the Ōtsutsuki Clan even here, there must be plenty more outside. When the time comes, I'll capture a few more and bring them back for you to cultivate with."
Hearing this, Orochimaru also looked delighted.
A long while later, the mark on Orochimaru's hand grew fainter and fainter before finally vanishing without a trace.
Ye Feng withdrew his palm as well and carefully sensed the changes within his body.
