In this punch, Su Yu still held back a bit of his strength. Otherwise, with full force, he could have smashed Han Xiao hundreds of meters away, causing him to cough up blood from his injuries.
Zhu Xiuqi merely stood to the side, quietly watching and not intervening, then sighed, shaking his head. He understood that even if he himself got involved, the outcome of the fight probably wouldn't change. Though Su Yu, Yang Yue, and Han Xiao hadn't used their full strength, the results of this battle were enough to gauge Su Yu's strength, which was definitely not less than that of the "666" beast Ning Yan, who had just successfully left this world.
The most terrifying thing about Su Yu was not his current strength, but that he was only at the Eighth Stage, yet could overpower these Ninth Level Peak warriors. If he were to reach the Ninth Level, just how powerful would he become?
That was the truly terrifying part.
