Ian stroked his chin, his eyes filled with doubt: "This mechanical structure... is very new."
"I believe that the civilization of the previous era used semi-mechanized Magical Beasts to guard their homeland. And the fact that these semi-mechanized Magical Beasts went out of control, driving the Humans away from the sanctuary, forcing them to build villages and towns on the first layer... I also believe."
"But..."
Saying this, Ian raised his hand and picked up a piece of the shredded Magical Beast's corpse. He carefully examined the Inscription Circuit on it and then shook his head, saying: "The civilization of the previous era used the anti-Spirit Energy coating and stealth circuit, technologies developed only in recent years. This I cannot believe."
He tossed aside the bug Flesh and Blood, then looked around at everyone, determinedly saying: "The bug may be old, but the mechanical structure is definitely new."
