Chapter 878: Breaking Out

Buzz! Buzz! Buzz!

Compared to the first punch, the force of Chu Nan's punch was much weaker. The vibration and vibration of the wall were much smaller, and the buzzing was also much weaker.

"Hahaha, Little Brother Chu Nan, don't waste your effort. Although I'm very surprised that you were able to destroy the Eflo memory metal, the defense level of this wall is two levels higher than the memory metal. It's impossible for you to rely on your strength…"

Jiggs's voice sounded again, but he was only halfway through his laughter when it stopped.

In the short period of time he spoke, Chu Nan had already thrown dozens of punches at the wall. His punches were abnormally fast, and the phantoms they brought about were connected.

At first, the wall only emitted a continuous buzzing sound like before, but soon, the frequency of this buzzing changed clearly. The vibration of the wall became even more shocking and had completely exceeded the normal range.
