Kant followed the mage and entered a room in the cabin.
After entering the room, the mage carefully closed the door and added a layer of soundproof effect to the room.
This room was located in the depths of the cabin and had no windows.
Other than one side of the aisle, there were other rooms on the other three sides. There were also other rooms on the opposite side of the aisle.
It could be said that this room was almost the most central room in the cabin. With the other rooms blocking it, no sound would leak out from this room.
This room was a place Kant used to communicate with his subordinates remotely. It had been specially modified, and the sound insulation effect was very outstanding.
