"Uncle Maori wants you to see this." Jiang Xia pointed to the key in the mini lake. "This is the key in the deceased's room. Because it was a new building that was built this spring, the door key also uses a relatively new inner groove design, which is difficult to copy."

"That's right!" Kogoro Mouri heard this information while chatting:

"There are only two such keys in the world, one in this and the other in the hands of the landlord's wife.

"The landlord's wife has been with us all the time, and when we came here before, the door was locked, a secret room - that is, the situation was already obvious, the deceased locked himself in the room and then committed suicide!"

Officer Meguri: "This..."

It sounds like it makes sense, but after having been in contact with Brother Jiang Xia for too much contact, the word "closed secret room" has gradually become difficult to associate with "suicide" in his mind - on the contrary, at this time, his mind is full of "artificial tricks."

Just as he was thinking, an excited voice came from beside him, and the landlord's wife interrupted, "Impossible! Ah Zhen won't commit suicide! - When I brought him juice this afternoon, he ordered vegetables and said that he wanted to eat pumpkin tonight. Will suicide do such things!"

"Have you seen him in the afternoon?" Officer Meguchi realized that this was an important time point and quickly asked, "When did you give him the juice?"

The landlord’s wife thought about it: “At around 6 pm, he doesn’t like having elders interfere in his life, so after delivering the juice, I didn’t leave much in his house and quickly returned to my house…”

She covered her face sadly: "I would have been fine if I hadn't left at that time."

Jiang Xia came over and patted her, and then asked a question that seemed to be unrelated: "What kind of juice are you sending?"

The landlord wiped his tears: "It is my special juice for cooling and fire reduction, and it adds honey, carrots, bananas, etc.... It's the one I used to treat you before."

She couldn't figure it out: "When I sent the juice, the child looked really normal, and there was no sign of suicide - and what reason did he have to commit suicide? Although he was in a bad mood recently, it shouldn't be enough to commit suicide!"

"this……"

Keihiko Tori whispered: "When I talk about my bad mood, Ah Zhen looks a bit strange recently."

"Hmm?" The police department of Megumi turned around and found that there was a stranger standing in the corner.

According to the normal process, he seemed to be ruthless and sternly driving people out of here, but judging from the words of this person...

After hesitating for a moment, the police officer with high tolerance in this regard chose to turn a blind eye and asked for clues: "Who are you, how do you know that the deceased is in a bad mood recently?"

"I am Ajin's friend." Keihiko Toruto pushed his glasses and sighed, "We are all seniors in Southern University and are facing graduation recently - I have heard him talk about his graduation thesis more than once, and Ajin's thesis seems to have encountered a lot of trouble."

"So that's it!" Kogoro Mori looked at his landlord's wife, "Didn't you ask Jiangxia to investigate why your grandson is depressed? - Now the situation is clear. He was troubled by graduation, became increasingly depressed, and finally suffered from depression!"

The landlord's wife was stunned: "Ah?"

Kogoro Mori looked at the wall again, which was painted in a mess by red crayons: "The wall was painted like this, and things in the cabinet were thrown everywhere - the appearance of a person's room could reflect his mental state. Although Mr. Ahma did not say it clearly, his spirit must have been on the verge of collapse."

The landlord's wife was skeptical: "But, when I went to deliver juice in the afternoon, he ordered what he wanted to eat tonight - Besides, what if he graduated or couldn't graduate? If it really doesn't work, he can come to see my apartment, so why bother committing suicide?"

Kogoro Mori shook his head, waved his hand like a lecturer, and said with a slight silence: "Suicide sometimes will be without warning. Maybe he maintained a barely calm last second, but suddenly collapsed the next second - as for helping you see the apartment... a person who is focusing on a goal often cannot see anything else. As long as the things are not done right now, he will collapse. So, young people now..."

The police officer of Megumi nodded while listening, somewhat convinced.

But suddenly, thinking of the past performance of Maori, an experienced police officer alertly stopped his thoughts and turned to Jiang Xia.

"Brother Jiangxia." The police department of Meguru leaned over, "What do you think?"

"I think?" Jiang Xia withdrew his gaze from the window and thought for a while. Soon, he pointed to the door key in the mini lake, "Then put away this physical evidence first and look at the material of the 'rope' on it."

"Hmm?" Meguro's police officer was stunned, and then he realized that this key was indeed a bit strange - ropes are common on the key, but the rope on the key is not a rope ring that is easy to carry, but a small broken rope.

...This does seem to be wrong.

While thinking, the police officer of Meguru obediently squatted down, stretched out his glove-wearing hand, and picked up the key from the water.

The next moment, he suddenly said "Ah!" - the key came out, but the small rope broke into the water.

"Such important physical evidence is actually broken!" The honest police department slapped his forehead, regretting it, but he was a little confused, "But I just picked it out of the water..."

Jiang Xia bent down and looked at the remains of the rope left in the water, with an expression not surprising: "It seems that the 'string' on this key should be made of toilet paper - tore the toilet paper into small strips and twist it hard, and it will become something like this."

"That's it." The police officer of Meguru patted his chest in fear, then looked at the two acquaintances of the deceased in confusion, "Why did he use such unsolid paper to tie the keys?"

The landlord's wife shook her head: She had never noticed what her grandson's usual keys looked like.

Keihiko Torito shrugged, "I really don't know this - it may not be good to say this, but Ah Zhen usually has strange things..."

As he was talking, a noisy sound came from downstairs.

The landlord's wife was stunned: "What's the sound?"

The police department of Memu sighed and had a headache: "It should be that group of reporters who saw us coming out and followed us - don't worry about them, let's continue to solve the case."

...

Downstairs, a group of reporters gathered at the door of the apartment, trying to find out the news.
