The people of the Dou tribe and the Clan of the Seven Slayers could sense that Yu Sheng and Dou Zhao were very similar. They were both skilled in pushing their power to its limits and at attack spells.
The fight between the two of them was like a clash between a God of Battle and a demon. They used only the most direct methods in their violent battle, and it was so overwhelming that those watching trembled.
The two of them clashed again as everyone watched. Neither of them had used any spell attacks yet, just strength, pressure, destruction, fighting will, and demonic will. The underground palace shook, and everyone's hearts trembled continuously as well. They were so strong. If they had been faced with such power, they were sure that they would not be able to withstand it.
Just the aftershocks of their violent collisions were enough to knock them back.
