The warehouse where the Magnetic Light Knight and the Purple Maple Knight met should be a raw material storage of an Alchemy Workshop; the door and windows were sealed tightly, likely welded shut from the inside. But when the Magnetic Light Knight reached out, the firmly sealed locks automatically gave way and fell to the ground.
The mist of Foresight View surged, and Ian saw through the walls that inside the warehouse, there were many kinds of magical beast parts and herbs, stored in individual sealed cabinets, where the Magnetic Light Knight and the Purple Maple Knight were exchanging information.
Ian found a restaurant close to the warehouse, ordered some drinks and ice treats, and sipped on red plum juice while remotely using Clairvoyance to eavesdrop on the traitor's conversation.
