"Oh?" Old Mo looked over in real time, then immediately his old face turned dark. Damn it, it was too far away; he couldn't see clearly...
This kid... his "vision" is that good too?
He glanced at Lin Yi, then realized that this might not be "vision," but a kind of "perception".
Once perceived, it was also "seen".
Heart's Eye, perhaps...?
"Rare opportunity, go and see if it can be used."
Saying this, Old Mo started trotting up the steps and reached the place Lin Yi had pointed out in just a few strides.
There's a very strange phenomenon in the staircase area of the Bell Tower: if you look around as you ascend, you'll notice some lifelike murals on the walls amidst the moss.
But if you don't look carefully, you would instead feel that the walls are covered with some three-dimensional Sneering Angels. Between paying attention and not, the wall's Sneering Angels convey a kind of eerie presence as if "existing in that space".
