160 Chapter 160: Passing Three Challenges, Promoting to Foundation Establishment Realm_1

Several days later.

In the middle of the night, a quiet chamber atop Immortal Mist Peak.

This is where Zhou Sui retreated for his cultivation practice.

Having spent several intimate days with Leng Yuexi, his yearning for her had completely subsided.

On this night, he suddenly had an insight. His divine sense, True Yuan, and vital energy had all resonated, seeming to reach a perfect balance.

Thus, he knew that his opportunity for Foundation Establishment had finally come.

Without hesitation, he immediately entered the quiet chamber to begin Foundation Establishment.

Boom-Boom-Boom~~

Zhou Sui was seen sitting cross-legged on the ground, operating Insect God Sutra. His body was at the center of a massive Spirit Energy Vortex.

Countless nature's spiritual energy flowed into his body.

No doubt, this was the third-stage Spirit Vein.

In terms of the concentration of spiritual energy, it surpassed the second-stage Spirit Vein by more than ten times.
