章 643: Chapter 523 What is prudence?_2

Allowing someone else to enter the protective barrier generated after triggering his Golden Core Secret Techniques and Lower-grade Spiritual Tool was tantamount to being in a completely undefended area with oneself.

If that person harbored ill intentions, He Song would likely suffer heavy injuries in an instant.

But one can never be too careful.

What if?

As for An Ning?

As a Foundation Establishment True Person, it wasn't a difficult task for her to protect herself.

With this thought in mind, He Song saw An Ning bring out her Defensive Artifacts; he too moved, heading toward the mine tunnel in front.

At the end of the tunnel ahead, in the huge cave, He Song's divine sense scanning revealed many traces of the presence of cultivators.
