Capítulo 641: Exchanging injury for injury

Guan Xilin didn't retreat. Instead, he countered and met him head-on. The mystical energy in his body burst forth. He leapt like a tiger, shaking his fists and attacking that teacher.

After tempering himself abroad numerous times, he had already cultivated his whole body ruthlessly. This teacher was at odds with him over words, then started using his fists. He was taking unfair advantage by using his real strength of Martial Ancestor rank. Even if Guan Xilin could not fight, how could he shrink back?

The two men threw down their fists one after another. Their breaths and power collided violently. Guan Xilin drew back several meters away, but the teacher also withdrew two steps.

The teacher raised his head in shock, both astonished and embarrassed. It was a disgrace that a student dared to take action against him and shook him back two steps!

"Young fellow, I will teach you a lesson today!"
