Bang!
A muffled explosion sounded in a remote forest of West Cloud Academy.
Chu Nan retracted his fist and nodded in satisfaction.
The experience he had obtained in the battle with Azalu during the day was indeed useful.
After returning to the academy, he repeated his daytime experience and used the Nine Revolutions Technique to mobilize his Internal Breath while practicing his fist. As expected, he could successfully fuse his Internal Breath into his fist and greatly increase the strength of his punch.
In fact, he had deliberately not adopted a perfect posture in this punch just now and displayed the strongest physical strength that this Sitting Horse Rush Fist could unleash. However, after complementing with his Internal Breath, the force attached to this punch was still as high as 623.371892 kilograms.
