Target Of A Probe

Behind Princess Isabella were Lucas and Lucia.

Lucas and Lucia looked at each other in a scrutinizing light and saw that they were all experiencing the same pressure.

They simultaneously received a soul transmission from their father, saying that the pressure that they were currently experiencing was not anything dangerous. 

Then they noticed that their mothers also didn't seem to be fazed much but it looked they were all radiating excited vibes for some reason.

Lucas and Lucia looked at each other again and nodded their heads, confirming that they thought about the same doubt.

Their father was somehow related to the Alstreim Family Territory!

It was just, their father hadn't still told them what kind of past he had with or in the Alstreim Family Territory, hence they didn't know about much.
