Next thing he purchased was the barrier upgrade [Complete Isolation], which could allow the inn to completely lose presence as required, which costs 5,000 Hearth Points.
It was the temporary solidification of the barrier. If he activated it, nothing would be able to come in or out of the barrier. It was closer to the locals' concept of a barrier.
In this case, the monsters wouldn't be able to sense them at all, even if he cooked seasoned meat outside for a picnic, or even if a fortified-level person was bleeding to death inside the barrier.
However, it could not be activated at all times. Apparently, it would only last 150 hours—which was just 5 days here—at a time, and it also had a cooldown of once every one month. Since it was not an emergency, he did not plan to activate it too often.
When he bought this, he already considered the Aphelion nights, which seemed to last a few weeks at a time.
