"Yumiko, look there."
I pointed on a vacant lot big enough for a megamall to be built not far from a farm near the edge of our city. It's devoid of people currently but something didn't feel right. From my eyes, the area was covered by a dense clump of Dark Energy which turned it into something like a concealed space.
If I didn't focus on it, I would've passed it off as something normal.
Compared to what I've seen in the fortress back in the World of Spirits, this one created an illusion that everything's fine and there's nothing wrong in its surroundings.
From the time we left our house, we're mostly walking on foot to scan anyone within our range. Yumiko will only occasionally fly while holding onto me for us to scout the area.
Well, there's someone else besides us and it's more efficient this way, the traces of the Dark Energy could be seen better on land than on air, especially if it is too thin.
