"The answer is not that."

Hearing Conan's words, Takeki Masumi threw ribbons in his hands and opened the lid of the treasure chest.

A golden rubber tube of the same color as the lock appeared in Conan's hand.

As for how to collect evidence, Ke Xin said that it was a tasteless method, and he expressed his disgust for it and wanted to say less.

Seeing everyone shaking their heads, Conan smiled and nodded, grabbing the key thrown in the air in his hand: "Now let's talk about that key. Because it was customized, there is no spare key, so it is so difficult to make a backup.

Before everyone left the room, Takeki Masumi closed the door.

"Please leave." Takagi's voice came from inside the house.

Even though they didn't have a premonition, they couldn't help but be slightly surprised when they saw Ke Xinzhen appear innocently in the treasure chest.

It was Guo Jianggu who confessed his guilt, but the situation was not handled properly, so Takagi took him away directly.

"He said afterwards that he hadn't eaten from morning till night, right?"

Following Conan back into the treasure chest, Dalan and the others saw that Takagi, who was supposed to be locked in the treasure chest, was actually standing next to the treasure chest, waving at us with a smile.

As for the murderer, you all have to rule out Mr. Kasuga who selected the theme fruit first. I'm sure it wouldn't take so much trouble for me to leak it.

"That's good. Then I'll go in next." Conan said this with a smile and flipped into the treasure chest, then cooperated with Sera Masumi to close the lid of the treasure chest.

Conan turned around and knocked on the door, "You need to leave now."

"The main trick in that trick was the old-fashioned structure of the purse lock."

"Hehe, so it's magic." Takagi said with a smile.

"You saw it all. The lock bar snapped back into the plug. Now if we have the key to the purse lock, we can open the treasure chest, right?"

"That's what you just asked the props staff to do."

"If you want to eat dessert, go ahead. Just because I've watched TV doesn't mean my cooking skills are bad."

Conan smiled and said, "Without that, you can unlock it. It would be more intuitive if I could actually demonstrate it to Xiaojia."

Now, I guess I can participate in the competition, but you can't taste the contestants' desserts!"

Takeki Masumi instantly approached Fūya Watari, scaring me so much that I kept moving forward, and you looked at him with a devilish expression: "If that's the case, then he must have not gone to the toilet yet. If that's the case, you should be able to come out sooner or later.

After slowly finishing the dessert, it was almost evening. Conan packed a cake for Ayako and then sent everyone home before driving back home.

"Get off now."

"We'll know after we wait." Conan said with a smile, throwing the key in his hand: "The key to that case lies in the locked treasure chest.

He must be the murderer who killed Mr. Tang Ze!"

Mr. Kasuga, who was the one who selected the theme for the competition, locked the treasure chest with a purse lock before selecting the fruits and sent it to Radio Nichima.

"Actually, the method is quite complicated. You put a rubber tube under the iron bars of the lock, and then force the rubber tube that has grown out back under the lock, and it's done."

“Ding-ding!”

Takeki Masumi smiled and said, "Before they all leave, you unlock the door and replace Takagi in the box. Before that, remove the rubber tube and lock it."

Maori Daishichiro looked at the scene in surprise and said, "You remember the purse lock was clearly locked, how could they switch it out?"

"Hey, Takagi, what tricks are they playing?" Maori Daishichiro couldn't help but ask, "What about Takeki? Didn't he tell you that you were outside the treasure chest?"

Before that, Mr. Kasuga opened the purse lock he had hung and sent it to Radio Nichimi. After the video recording on the show was finished, it was kept in the warehouse.

"He, he says that without evidence?" Although his crime was exposed, Wataru Fūya still managed to refute him weakly, "What he said was just speculation. Even if you are the least suspicious in his reasoning, he can still arrest you!"

Ke Xin smiled and said, "Half is the lock, and the other half is the U-shaped iron bar. Even though the lock core is low-tech, the structure of the lock determines that it is flawless and cannot be exploited.

"Really?"

Conan also looked amused: "I'm sure he really drank so little seeds. I guess his body will be deprived of oxygen and blood soon."

That's not the whole story of the case, don't you understand anything?"

Although the punishment was heavy, Conan was very satisfied when he saw the wallet with less than 2,500 fate points.

"Save you! Save you!" Fūya Watari looked at Conan and said, "You wanted to go to the hospital because of poisoning. You killed Mr. Tang Ze. You did everything!"

As Takagi took out the lock, Conan knocked on the treasure chest and said, "It can't come out."

So, I will let you witness with your own eyes how the criminal managed to place the body in the treasure chest before committing the crime."

Seeing everyone nod, Takeki Masumi smiled and handed the key to Conan: "Then I'll ask Detective Ke Xin to take the key and lead us out."

"Brother-in-law, what are you keeping in suspense?" Sonoko looked at Conan curiously.

Takeki Masumi smiled and knocked on the treasure chest, then locked it before hearing Takagi's response:

However, in the surveillance video, he didn't take anything when he came out.

Looking at the pale-faced Jyougu Watari, Ke Xin said calmly, “In order to get his reward, he traded the contest questions in the treasure chest with the champion, Mr. Kurimura.

"How is that possible!"
