Emperor Sacred Niu thought viciously in his heart.

"Let's go, lead the way."

Ning Qi smiled, and tossed it casually. The Holy Bull quickly stabilized his figure in mid-air, glanced at Ning Qi, and then entered the dense fog expressionlessly. Soon, Emperor Sacred Niu led Ning Qi through the thick fog and came to a hall that looked very old. When Ning Qi was still at the entrance of the hall, he noticed a very terrifying atmosphere in the hall. The Dao breath is estimated to be different from when Ning Qi's nine doors are fully open and the seven doors are fully open.
