Capítulo 575: The Furious Qin Yu!

Qin Yu's fist was extremely fierce. This was practically all of his strength!

"Clang!" 

The sound of this punch instantly became louder!

But the iron cage still didn't move at all. It wasn't affected at all!

"How... how could this be..." Qin Yu's expression was extremely flustered.

He refused to give up and once again clenched his fist to smash it.

One punch, two punches, three punches!

Clattering sounds continued to be heard and spread throughout the entire prison.

However, this iron cage wasn't affected at all!

Qin Yu hurriedly took out his bronze sword. He bit his finger and dropped a drop of blood essence onto it.

Then, Qin Yu held the bronze sword in his hand and ruthlessly hacked it down!

"Clang!" 

Another loud sound rang out. Not even a single line was left on the iron cage!
