Chapter 1556: Learn physics well, and you won’t be afraid of committing crimes

"Well, it is indeed necessary to investigate clearly."

Hearing Karasawa's words, Officer Megure nodded and led everyone from inside the swimming pool to the exit, where he found two front desk ladies to express their intention.

According to the front desk lady, after the above instructions were given to block the swimming pool, only relevant personnel could enter it.

That is, Toshima Ensaku, Oiso Hamaka, and Sanomaki Raito, as well as the two waiters who found the body.

Of course, Xiaolan and her group also entered it.

However, they were definitely not suspicious, so Tang Ze quickly ignored this.

This was true for Officers Takagi and Megure, and it was obvious that Xiaolan and the others were not included as suspects at all.

After all, they are all frequent visitors to crime scenes. It can be said that they are accustomed to it, and they will not be suspected at all.

After Oiso Nagami lost her temper and said she wanted to find the necklace by herself and kicked the others out, Karasawa also confirmed it with the receptionist.

The first person to return to the swimming pool was the manager Toshima Ensaku. He said at that time that he wanted to see how Miss Nagami was doing.

As for the return time, because a receptionist received a text message at that time, it was definitely at 12:05.

According to Toshima Ensaku, the deceased Oiso Nagami was still looking for the necklace in the swimming pool and did not even notice that he returned to the swimming pool.

But after he spoke out, the other party drove him away out of disgust.

After manager Ensaku Toshima left, the second person to come to the swimming pool was Raito Sanomaki.

According to Toshima Ensaku, when he went to find Oiso Nagami, she had already spent a lot of time in the swimming pool, so he planned to persuade the deceased to ask someone else to find him.

But when he came to the swimming pool, he found that there was no figure of Oiso Nagami in or on the side of the swimming pool.

At first, he thought Oiso Nagami had gone to the bathroom, so he stood by the swimming pool waiting for Oiso Nagami.

But the other party never came back, so Raito Sanomaki, who couldn't wait any longer, went back directly.

Although no one remembers when Sanomaki Raito went back, after Sanomaki Raito went back, Oiso Hamaka, who came to the swimming pool, went back at 12:54.

The reason why it was so clear was because Oiso Hamaka asked the front desk about the time.

"Why did you ask for the time at that time?" Officer Megure asked after hearing this.

"We agreed to have dinner together at one o'clock, so Mr. Raito asked me to go to the bathroom or dressing room and call my sister."

Oiso Hamaka said: "But I searched both places, but I didn't see anyone at all, and I didn't see her in the swimming pool.

I thought the time on my mobile phone was wrong, but it was actually already the time so my sister left, so I thought about confirming the time with the front desk. "

"Excuse me, where are the bathrooms and locker rooms you mentioned?" Takagi asked.

"Over here." Yuanzi heard this and pointed to the entrance and exit between the front desk and the swimming pool corridor: "There are the locker rooms and shower rooms, and the innermost one is the toilet."

"As long as you use the space here, you can easily hide the body." Officer Megure came to the corridor door and said.

"Yes, and this corridor happens to be in a blind spot where the two counter ladies cannot see." Takagi agreed.

"Then what did you do after that?" Officer Megure turned around and continued to ask, "Did you guys look for Oiso Nagami?"

"Of course I did."

Oiso Hamaka nodded repeatedly and said: "I asked them to call Mr. Manager and Mr. Sanomaki. I also called the waiters over and started looking for my sister separately."

"But we didn't find her at all." Toshima Enzai said: "I also looked in the swimming pool, and there was no sign of the eldest lady at all."

"I even looked for the locker in the shower room." Oiso Hamaka said seriously.

"Me too, I've also searched for various facilities and spaces on the men's side."

Laito Sanomaki immediately echoed: "I even yelled Yongmei's name, but I searched inside for an hour and couldn't find Yongmei's whereabouts.

Just when I ran out to confirm with the two front desk ladies that Yongmei had really not left, Miss Sonoko came over with her companions. "

As he said this, Raito Sanomaki pointed to Sonoko and the others next to him and said, "And just when I was explaining the situation to them, the two waiters over there suddenly shouted that they had discovered Nagami.

Then when we ran to the swimming pool, we found Yongmei sinking in the middle of the swimming pool. "

"I have a question."

After listening to Sanomaki Raito's explanation, Karasawa looked at the two waiters and asked: "When you were looking for it before, you should have searched the swimming pool in advance, right?

Why go back again? "

"Should I say that I suddenly had a bad premonition?" The thinner waiter looked hesitant, and the words in his mouth made people look confused.

"We were nearby, and it seemed like there was a strange sound coming from the swimming pool."

Another slightly fat waiter saw everyone's expressions and quickly explained: "It's the sound of "gubo", like the sound of big bubbles coming out."

Hearing the waiter's words, Tang Ze and the other three were stunned for a moment and then realized something. They quickly turned around and ran towards the drain of the swimming pool.

"As expected, the drain outlet is fixed with screws." Tang Ze said while squatting under the swimming pool wall.

"Not only that, there is something similar to a hook above the swimming pool at the drainage outlet." Sera Masazumi said.

"And this location is the center of the swimming pool." Conan said when he turned to the center of the swimming pool, the corners of his mouth raised slightly: "The prisoner is that person."

"It's really a lot of trouble." Tang Ze sighed and waved to the forensic examiner on the side, and said to the two of them at the same time: "I just put the water in, and I have to put it in again."

"There's nothing we can do about it." Sera Masaki said with a smile: "In order to prove the murderer, this is the only way."

"Tang Ze Criminal, did you find anything?" The forensic examiner on the side asked immediately after running over.

"There are some, but I didn't call you here to collect evidence." Tang Ze said: "There are some things that I need to trouble you to prepare."

"Do you have a clue about the case?"

The experienced forensic examiner's eyes lit up when he heard this, and his expression immediately became excited: "I know, get ready right away!"

As a forensic examiner who follows him to crime scenes all year round, he is already very familiar with Tang Ze and naturally knows about Tang Ze's various behaviors.

And asking them to prepare some things basically means that Tangze has solved the case.

That's why Tang Ze was so excited after hearing his request.

Not only are they happy to solve the case, but it also means that their work is basically over!

After all, there is a huge amount of evidence that needs to be investigated that is hovering between "useful or not". Now we only need to select the useful part of the evidence and collect it.

In this case, the workload is naturally reduced exponentially, and he is naturally very happy. After instructing the forensic examiners to prepare, Tang Ze led the two of them back to the front desk.

"Brother Tang Ze, did you notice anything when I saw you running away in such a hurry just now?" Officer Memu's eyes lit up when he saw Tang Ze come back, and he couldn't help but ask.

"I already have a clue. All that's left is to wait for the venue to be decorated." Tang Ze said with a smile: "Before that, let's wait a little bit."

"Oh! It's so reliable!" Officer Memu couldn't help but cheered up after hearing this: "The suspect must have already had a clue about the suspect."

"Judging from the current timeline, these three are naturally the suspects."

Tangze opened his mouth and pointed at the three people standing aside. After hearing his words, the expressions of the three people present could not help but change, and their expressions became uneasy.

"The most important thing to solve a case is evidence. Now I am making arrangements. You three should wait patiently."

Looking at the three people with panic-stricken expressions, Tangze didn't mean to comfort him. He just pulled Takagi to say a few words, and waited with everyone after the other party left.

As the large water tank prepared by the forensic examiner was moved into the swimming pool, Tang Ze waited for a while and then led everyone to the swimming pool.

"Brother Karasawa, you can start now." After arriving at the swimming pool, Memu looked at Karasawa and said.

"Prior to this, Criminal Takagi has actually come to the swimming pool." Tangze smiled and talked about an unrelated topic.

"Takagi?"

As expected, these words attracted Officer Memu's attention. He glanced around and then looked down at the swimming pool filled with water. He couldn't help but asked in shock: "You said he is here, where is he?"

"It's in the swimming pool." Tang Ze said with a smile and pointed at the water.

"Eh? How is this possible!?"

Although he knew that Karasawa was showing him the criminal's tricks, he was still shocked when he heard that Takagi was in the swimming pool: "There is no figure of Takagi in this swimming pool at all. Do you think you can see Takagi?" "

"Now, we can't see Takagi's figure." Tang Ze smiled slightly and said, "But as long as we cut the fishing line on the hook, we can see it."

Following Karasawa's words, Conan on the side also took out a folding knife and pushed out the blade. He half-crouched to the edge of the pool and cut the fishing line on the hook they had discovered before.

"Gubo!"

There was a sound like a big bubble bursting, and the next moment Takagi suddenly emerged from the water holding the sink.

"T-Takagi Criminal!?"

Seeing Takagi emerging from the water in a swimsuit, Memaku, Xiaolan and others couldn't help but exclaimed.

Although they had already guessed from Karasawa's words that Takagi should be in the swimming pool, they still couldn't help but feel surprised when they saw someone suddenly appear in the originally empty swimming pool.

"You probably didn't see me just now, right?" Takagi panted for a moment, then looked at everyone expectantly and asked.

"Indeed, indeed." The look of surprise on Officer Mumu's face continued, "But, but why?"

"It's the total reflection of light." Sera Masaki said with a smile, which also made everyone's faces even more confused.

"It's a very simple reason." Tang Ze said: "Although water and air are both transparent, they have different refractive indexes for light.

Simply put, it is when light travels from water with a higher refractive index to air with a lower refractive index.

If you look directly at the intersection of water and air, the light will be reflected back, just like a mirror. "

"And this way, you won't be able to see what's on the other side of the interface." Conan agreed.

However, the explanations of the three people seemed too "textbook-style". Even if they repeated the principles, the officers Memu, including Xiaolan and Yuanzi, who heard their words, all looked confused.

Obviously I can understand every word of the words, but when connected together, it's like listening to a book from heaven, with a confused look on his face.

"The actual result is what you see."

Tang Ze smiled and said, "But in order to give you a clearer and more intuitive understanding, let's give a simple demonstration."

"Do you want to demonstrate?" Officer Memu heard this and asked curiously: "How to do it?"

"Takagi, please."

Karasawa shouted to Takagi in the swimming pool, and he dragged the water tank closer to the shore.

Sera Masumi and the forensic examiners on the side approached to help and quickly sent the water tank out of the swimming pool.

After filling the sink next to the swimming pool with water, Conan took out a coin and threw it into the water: "Look, can you clearly see the 10-yuan coin I threw into the sink now?"

"Yeah." Xiaolan nodded.

"But if I turn it over with a glass of water and cover the coin while there is still air inside."

Conan tipped the water glass upside down and the coins inside disappeared in the next moment.

"No, it's gone!"

Officer Megure and others couldn't help but exclaimed when they saw the scene in front of them.

"Conan, you are so awesome!" Xiaolan saw the look of admiration on his face: "Did you also learn this from Tang Ze Criminal?"

"No, this is just a science experiment."

Hearing Xiaolan's words, Conan's heart twitched and felt a little painful.

Although no matter what he did now, Xiaolan would no longer doubt him because of his status as "Tangze's disciple".

But the bad thing is that everything seems to have been attributed to Tangze Criminal, and he is completely shrouded in the shadow of the other party.

This couldn't help but make Conan, the "King of Forces", a little unhappy. A little bit of rebelliousness arose in his heart, making him feel the need to explain this principle, which even a primary school student could understand.

"Sister Xiaolan, you should have learned related science experiments when you were in elementary school." Conan said.

"is that so."

Xiaolan smiled awkwardly when she heard this, and Yuanzi secretly recalled whether she had ever learned such science experiments in elementary school.

"You have all seen the situation. The situation in Takagi Criminal Case is roughly the same."

Tangze said: "He was in the tank that was upside down in the swimming pool and there was still air, so he couldn't see him in the swimming pool.

Of course, this also has loopholes. "

Having said this, Tang Ze pointed to the top of the water glass and motioned for everyone to take a look.
