One of the items Agni told Kent he can use in forming his core is the Nether Green Flame Essence. He told him that to form a core, he must have some of the best and most powerful resources available.
The Nether green Flame Essence is said to come from the Underworld. It is a flame essence used in purifying holy relics to imbue them with Nether energy.
Essentially, it is used to counteract divine energies. If Kent were to use it in forming his core, he would gain the essence of the Nether green flame, allowing him to have some edge over divine energies.
The Soul Flame Fruit is one that goes against the soul, and now he will be getting yet another powerful treasure.

"You guys can leave," Kent said, and they bowed slightly and left. Kent then turned to Niraya, who was still kneeling on the ground.
"Stand."
