Chapter 421: Return to Emperor Domain (Fourth Update)

As days went by, under the suppression of the True Yang Power, the Nether King Gu Poison continuously gathered towards the underground space where Long Yan was located. It then entered the Nine Suns Divine Cauldron and was refined into pure energy.

After purification by the Nine Suns Divine Cauldron, the Nether King Gu Poison transformed into pure energy. If all the Nether King Gu Poison could be refined, it would be an enormous amount of energy. However, these energies were not absorbed by Long Yan. He integrated these energies into the Heart of Divine Martial.

After the huge calamities, the Shenwu Continent had been depleted of energy. Once the energy was depleted, it became harder for martial artists to make breakthroughs. The energy converted from the Nether King Gu Poison could be used to nourish the Shenwu Continent. This energy originally came from the Shenwu Continent.
