Bab 644: Could It Be That He Was Qin Yu!

After raising his head to look at the black-golden light, Qin Yu let out an angry roar. His fist immediately shone with a golden light as he met it head-on!

"Hmph, a swordmentor dares to use his physical strength to fight. He's simply courting death." 

Seeing this, the few of them couldn't help but sneer.

One had to know that usually, a swordsman's physical strength wasn't that good. One could even call it his weakness!

However, they didn't expect that the person under the black robe was Qin Yu!

"Clang!" 

The moment the fist collided with the black-gold light, the entire ground was instantly filled with dense cracks!

Even the Martial Arts Academy in the distance began to crumble!

Crushed rocks shot out like bullets, and the crackling sounds could be heard continuously!

"Ah!!" 

Qin Yu kept roaring. His veins bulged, and his physical strength was pushed to the limit!

"Boom!"
