I can always see something that others can't.
If I want, I can see a person wearing ten pairs of pants, whether the underwear underneath is dark red or gray. As long as I am willing, I can see how many hairs grow on the thighs of a person ten feet away.
Of course, I can still see ghosts.
My adoptive father said that this is my heavenly eye, which is rare in a thousand years and very precious.
