Eren withdrew his hand from Trisa's clothes, revealing the object he held.
"This is the reason I did this."
"This is...?" Trisa looked at the object in his hand, her frown deepening. Shock flickered across her face.
In Eren's hand, there was no storage ring. Instead, he held an insect that could only be found in the Upper Realm. It was an energy-devouring insect, a common sight in the Upper Realm, including in the city where they were staying.
It wasn't a lethal insect, as it could only devour a person's energy, not kill them. The only danger was that if left on the body for too long, it could consume almost all of their core energy, leaving them weakened for at least a few days.
"We are in the Central Region. As you said, it's a dangerous place where anything can go wrong. If I left the insect, it could have weakened you. It would have made things more dangerous for me in the long term as well, since I can only rely on your protection until I reach the Territory of Arcadia."
