Chapter 166: Chapter 161: A Visitor from the Kong Family_1

An astonishing rate of progress!

Huang An's gaze was scorching, full of life and his eyes radiating with barely concealed joy.

Such a refreshing feeling, he could feel every muscle, every bone in his body responding to his commands, contracting and relaxing at will.

The practice of body-building technique became more natural and effortless.

Compared to yesterday, he had clearly leveled up.

After a while, the bubbling energy within him returned to calm. Huang An could clearly feel that his vital energy was slightly stronger than before.

This was too incredible!

Suspicion sparkled in his eyes, swiftly replaced by surprise.

"The growth in spiritual power is incalculable, but my martial arts practice speed has probably increased by twenty percent!"

This effect was too powerful that Huang An was in a daze for a long time.

Defiantly, he tried the body-building technique again, and just like before, he improved once more.
