There’s actually something that she can’t do

Little Seven sat next to Qing Yi. She scanned the dark surroundings. "Qing Yi, why don't we go by air instead of traversing on ground?"

"Sometimes the space looks the same, but it's distorted. We seem to be walking straight, but we may be going astray." Qing Yi explained. "And I am more familiar with the ground. When we walk on the ground, I can tell where we are." 

"That's it." 

Everyone's doubts were cleared. But they did expect him to have such a fastidious attitude.

Others didn't know, but Sima You Yue understood the remains of someone of emperor rank would definitely not be easy to find. If they were to make spatial changes, it was a piece of cake to them. 

She estimated that they have been underground for five to six days. Qing Yi led them back onto the continent.

He waved his hand, and the aperture disappeared.

"Is this the ruins?"

They looked around and saw no one.
