The Eye, The Black and White (ll)

The white pupils, clear like crystal gems flickered on his forehead without permission and glared at the skies. Harry could feel his thoughts coming to a halt.

But he didn't panic, and the system screen flickered in front of him.

[A forceful attempt of information infusion is going on.]

"W..what?" 

It only said that and didn't elaborate. A cold sensation spread out inside his brain as if a cold nail was hammered into it.

He grimaced in pain and his body sweated profusely. Information from all corners of his mind combined and immediately, new knowledge started to appear in it.

New knowledge that he had been completely unaware of.

The system sorted out all that and immediately added the new knowledge to its ancient database.

The pain vanished and he calmed down, but the white Eye didn't close and was still wide open in his forehead.

Just like the black eyes were wide open in the heavens.
