The Nine Nether Yin Fiend churned as if alive, rapidly intertwining and colliding with the dense Heaven and Earth Primordial Qi in the secret chamber to form a small, dark vortex visible to the naked eye, with Chen Sheng at its center.
With a tremor of his arms, the Qi and blood in Chen Sheng's body surged like a mighty river, letting out a roaring sound.
Within his Dantian, the fully perfected Innate Spirit Seed sensed the external pressure and automatically emanated a brilliant Profound Light, preparing itself for assimilation and conversion.
The next moment, he channeled his Cultivation Technique with all his might, generating a powerful suction.
The Nine Nether Yin Fiend permeating the secret chamber was drawn in. Like rivers flowing into the ocean, it surged frantically into the major acupoints all over Chen Sheng's body.
"Argh—!"
The moment the Evil Qi entered his body, Chen Sheng could not help but let out a suppressed growl, his face instantly twisting in agony.
