The masked man strode forward, and the chilling aura around him made Conan uneasy. Conan immediately took a few steps back and lay down on the ground, his back to the cave entrance, while Kōyū hid in the cave's blind spot.

The masked man crouched down, peering into the room through a hole in the door with his narrow eyes. Seeing this, Fumiyo asked, "Has that brat gotten up yet?"

The masked man didn't even turn his head, looking into the room, and said, "Not yet. I think the drug is still probably working. But is that kid inside really that high school detective, Shinichi Kudo?"

Fumiyo looked at the masked man and said, "I still don't quite believe it. However, the day Shinichi Kudo disappeared was the same day this kid entered the agency. I remember another kid also entered the agency that day, but after investigating, he was an orphan adopted by Ran, so there shouldn't be any problems. After that, everything that happened to this kid was resolved perfectly. I think it must be the side effects of the new drug developed by the organization that made Shinichi Kudo shrink."

The masked man sneered and said, "That's quite interesting. I'll give it a try!"

Seeing the puzzled look on Wen Dai's face, the masked man explained, "I happen to have some of that newly developed drug on me. I can find out if it can shrink people by having other people take it."

The masked man pulled a metal box from his pocket, opened it, and revealed six red and white capsules. He continued, "Isn't there a man who's going to make a deal with us tomorrow? The organization already instructed us to get rid of him as soon as the deal is over, right?"

Looking at the capsule, Fumiyo said, "If you knew that this medicine could actually shrink people, what would you do?"

The masked man looked around the room and said, "Anyway, kill the man who made the deal first, and then take care of that brat!"

Wen Dai hurriedly said, "No! The organization needs this kid; they need to study the side effects he's experiencing!"

Wen Dai wanted to argue, but the masked man's patience was running out. He pulled out a gun from his pocket, pointed it at Wen Dai, and said, "I said I'll take care of it, and I mean it. If you keep arguing, I think you want to lie here forever?"

A bead of cold sweat appeared on Wen Dai's face. He nodded, indicating that he dared not continue.

Seeing this, the masked man put away his gun and said, "By the way, did you tell that man the location of tomorrow's transaction?"

Wen Dai nodded and said, "Yes, let's use our old method."

The masked man then said, "That's good. The trading time is at 1 PM tomorrow. We need to get a good night's sleep."
