"There's something looking at me!"
Qin Mu's heart leaped. Even though he didn't see the two eyes hidden in the darkness, he could feel their gaze.
He turned around, away from the bridge, and closed his eyes while slowly walking outside. His footsteps weren't slow nor fast, and even though he had closed his eyes, he had still walked a circle, a perfect circle.
After he did so, Qin Mu stopped. The reason he walked in a circle was to calculate the precise location of the gaze. This involved using algebra skills to calculate space.
To other people, he would only be pacing around while thinking of some problem. No one would expect that he was actually calculating the location of the watcher.
His mind was greatly shaken. In the few steps, he had determined the source of the gaze and some extra information.
What was watching him was a pair of eyes, the distance between which were nine hundred yards! What a humongous entity!
