Chapter 472 How the Secret Room was Built

After Yuya left, the remaining people investigated the room and then went to the restaurant to prepare dinner.

Before dinner started, Nanatsuki Koshimizu stood up and said, "I'm going to the bathroom."

After a pause, he continued, "Eat slowly, don't finish all the food."

"Ah, don't worry." Hattori Heiji answered without raising his head, but his mouth movements did not slow down at all.

Nanatsuki Koshimizu came to the bathroom, but she did not go in. Instead, she stood at the door and hesitated for a long time. After looking around to make sure that there was no one there, she tiptoed towards the second floor.

When passing by Yuya's room, Nanatsuki Koshimizu subconsciously looked at the door.

As if in response to her expectations, the door suddenly opened and Yuya walked out holding an envelope.

Both of them were a little surprised to see each other.

Nanatsuki Koshimizu was slightly flustered, but she managed a smile and said, "Kamiya-san, it seems that you have already written down the reasoning process?"

Yuya nodded slightly and looked at Koshimizu Nanatsuki with deep eyes.

Nanatsuki Koshimizu felt a little flustered when he looked at her. She adjusted her scarf as if she was embarrassed and asked shyly, "What's wrong, Kamiya-san? Is there something strange about me?"

Yuya shook his head and smiled, "Koshimizu-san, it seems you have solved the secret room trick as well?"

Nanatsuki Koshimizu was stunned for a moment: "Ah, this..."

Yuya asked again: "Are you going back to your room?"

Before Nanatsuki Koshimizu could answer, Yuya continued, "Or do you want to go and check your answers with the northern representative?"

Nanatsuki Koshimizu was shocked, but she pretended not to know: "No, I just wanted to go back to my room to get something."

Did he notice something? Otherwise, knowing that it was the time of the competition and that Kotani Renzo had specifically reminded him, why would he ask such a question?

"I see." Yuya pretended to be ignorant and said, "I was just about to go find him to get the answer."

Koshimizu Nanatsuki smiled unnaturally: "But aren't we still in the competition? Mr. Kotani also said that we can't tell others about our reasoning process in advance."

"It's okay," Youya waved his hand, "He and I both claim to have solved the secret room. As a detective, you should have enough confidence in your own reasoning, so even if the other party's reasoning process is different from yours, you must insist that you are correct."

Nanatsuki Koshimizu had a puzzled expression: "Is it right to insist on being myself...?"

Youye smiled and said, "Of course, if your reasoning is wrong, you must be brave enough to admit it. After all, reasoning about a case is not a game. If you make a mistake, you may wrongly accuse an innocent person and cause something irreparable to happen."

"Are you right about what I said, Nanbu representative, Koshimizu-san?"

Koshimizu Nanatsuki's mind was filled with thoughts, but she managed a smile: "You're right."

Youye said, "Okay, then you go get your things. I'm going to look for the northern representative students." Then he turned around and prepared to leave.

"Wait a minute, Kamiya-san." Nanatsuki Koshimizu suddenly called him.

Youya turned back: "What's wrong?"

Koshimizu Nanatsuki was silent for a while, then said, "Can I go with you?"

Yuya hesitated: "Hmm? But you..."

Nanatsuki Koshimizu said quickly: "In fact, I have some theories about the secret room. Seeing you are so confident, I can't be sure whether it is right or wrong, so I didn't say it just now."

"Is that so?" Youya pretended to think about it for a moment, and finally nodded, "Okay then, come along too."

Nanatsuki Koshimizu breathed a sigh of relief, but she felt a little anxious again.

If You was present, she would have no way to do anything. If he was really as the rumors said, could she trick him away with his ability?

The two came to Tokatsu Junya's room, and Yuya raised his hand and knocked on the door.

"Who?"

"It's me, the Eastern representative, Yuya Kamiya."

Tokitsu Junya quickly came over and opened the door, and was a little surprised to see Yuya and Koshimizu Nanatsuki appear together.

Youye raised the envelope in his hand and said with a smile: "I have already written down the reasoning process. How is your secret room prepared?"

Tokatsu Junya was a little surprised, but also felt it made sense: "As expected of you. Not yet, preparing a secret room is not as fast as writing."

"So, what do you want to see me about?"

Yuya smiled slightly, "I'll check the answer with you."

Tokatsu Junya was stunned: "Correct answer? But..."

Youya waved his hand and said, "Don't worry, I have written down the entire reasoning process. I will submit the answer based on the content here. I will not change it no matter what the result is."

"Now that you and the southern representative are here, you can both serve as witnesses. You won't be afraid that I'll cheat, right?"

Tokatsu Junya laughed dryly, and immediately returned to his previous confident look: "Of course I believe what Kamiya-san said. But this Nanbu student, Koshimizu-san, right? What about you, have you figured out the locked room method?"

Koshimizu Nanatsuki hesitated for a moment, then nodded and said, "I have a rough guess." Then he took out a folded envelope from his right pocket.

Seeing this, Tokatsu Junya nodded with satisfaction: "Come in and talk."

The three of them entered the house.

Yuya quickly scanned the room and found that the windows had been dismantled and the screws used to fix them had been removed. Some of them had been cut in two. Next to them was an open tool box, a set of tools, and a bottle of adhesive.

Shi Jin Runya said: "My secret room is more convenient, so let's start with me."

Seeing that the two had no intention of objecting, Tokatsu Junya walked to the desk by the window, picked out a complete screw and a cut screw, and showed them to Yuya and Koshimizu Nanatsuki.

"Mr. Hammertail was ambushed and tied up. There shouldn't be much to reason about. The key is how to arrange the room into a secret room. Please read this."

Tokatsu Junya pointed at the dismantled window and pinched the intact screw and said, "This kind of embedded window is fixed to the window frame with screws. As long as the screws are removed, the entire window can be taken down directly."

He held up the cut screw again: "Next, cut off the end of the screw and put it back into the screw hole according to its original position."

Tokatsu Junya pressed half of the screw into the screw hole and tightened it with a screwdriver. Then he said, "This way, it will look no different from the original."

Yuya and Nanatsuki Koshimizu nodded slightly, and it was obvious that they had both deduced to this point - in fact, both of them had the script in their hands, but one knew the plot, while the other knew the method and was also the planner behind the scenes.

Of course, Tokatsu Junya didn't know the true situation of these two people, so he continued to arrange the secret room.

"Next, apply adhesive around the window frame..." He opened the bottle of adhesive and applied a full circle of adhesive along the removed window.

"Finally, just put the window back in its original position, while being careful to cover up the signs of disassembly. After the adhesive dries, the window will be the same as if it had never been disassembled."

Yuya clapped his hands, "Excellent reasoning and such skillful techniques. I almost thought that the Northern Representative had solved the same case before."

Tokitsu Junya's expression changed slightly, and Koshimizu Nanatsuki also subconsciously looked at Yuya, with a hint of shock in his eyes.

The two of them had the same thought in their hearts:

Does this Yuya Kamiya know something?
