Chapter 244: Chapter 214 Advancement to Late Foundation Establishment, Three Challenges in Core Formation_3

Immortal Mist Island had lost the opportunity for Nascent Soul because of losing the fourth-stage Spirit Vein in the past.

This led many Golden Core cultivators to leave Immortal Mist Island to find opportunities for Core Formation.

If a fourth-stage Spirit Vein existed in this place, then they could also form their cores here.

They wouldn't need to borrow another fourth-stage Spirit Vein to form their cores.

The significance of this is self-evident.

However, after carefully sensing, they still couldn't find the existence of the fourth-stage Spirit Vein.

Thinking about it, this was quite normal.

If a fourth-stage Spirit Vein could be found so easily, this island would not have been given up by the Wuji Alliance.

"My lord, if there really is a fourth-stage Spirit Vein, where could the source be?"

Shen Biqian asked curiously.

"It's not in the island, but under the deep sea."

Zhou Sui let out a faint smile.
