Chapter 642, Unbeatable After Leaving the Pass

Xu Wendong had no idea what was happening outside.

At this moment, he was in great pain, completely focused on refining the Boundary Stele deep within his Sea of Consciousness.

Although his progress was extremely slow,

for him, as long as there was a one-thousandth advance, the pain his soul endured would lessen somewhat.

Moreover,

his Soul Force would also improve.

It had been mentioned before that his Soul Force had long surpassed that of ordinary cultivators in the Qi Refinement Realm, reaching the level of a Foundation Establishment Stage expert.

And now, his Soul Force welcomed yet another enhancement.

Although Xu Wendong's face was full of pain, and his eyes were blood-red, there was an excited gleam in his gaze.
