"Don't tell me! Takagi, he, he, he, he, he, he, is dead?!" Officer Megure had a frightened expression on his face, with a look of unbelievable horror.
Xiaolan and Yuanzi also stared wide-eyed, with confusion written on their faces.
Sera Masumi couldn't help but put her hands on her hips and laughed, "Naika, please stop teasing them."
Chun Riling stuck out her tongue, her beautiful blue eyes flashing, "Slightly."
immediately.
She came to a place, "We can't see Takagi now, but as long as we cut the underwater fishing line."
The girl was talking and Conan was doing it.
The moment he cut the underwater fishing line with a utility knife.
Bubbles suddenly appeared on the water, and then a corner of a water tank appeared out of thin air!
Seeing this, Officer Memu was shocked and lost his voice, "Water, sink?!"
"call!"
Takagi's head emerged from the water, and he gasped for air.
"Gao, Gao Mu, Officer Gao Mu!"
Everyone exclaimed, with disbelief flashing in their eyes.
Takagi hugged the sink, he came over and looked happy, "You didn't see me just now, right?!"
"Yes...yes, but why?" Officer Megure was completely confused by this scene.
Sera Masumi walked straight to Kasuga Ling, put his arms around the girl's shoulders, and smiled slightly, "It's the total reflection of light."
Hearing this, Officer Memu turned around with a look of confusion on his face.
Chun Riling's blue eyes seemed to be shining like stars, and her voice was clear and crisp, "To put it simply, although water and air are both transparent, they have different refractive indexes for light.
When light travels from water with a higher refractive index to air with a lower refractive index.
If you look directly at the interface between water and air, the light will be completely reflected back and become like a mirror.
This way you won't be able to see what's on the other side of the interface. "
With several people listening in confusion, Bai Mao Tuanzi completed his explanation.
Seeing that the others were still staring in confusion, Conan said happily, "Then let's just give a demonstration!"
Beside it, a small sink had been placed early.
Officer Memu felt helpless, "Did you think that others couldn't understand you earlier?"
Kasuga Ling grinned widely and said, "No, I just want to give Conan a chance to do experiments. After all, he is a primary school student, so he can develop his hands-on ability."
"He is not an ordinary elementary school student." Officer Megure sighed, and came to Conan to watch the experiment.
Conan rubbed the back of his head sheepishly and laughed.
Don't wait for him to speak.
Officer Megure continued, "It's the elementary school student possessed by the god of death who won the perfect attendance award for murderers in Tokyo.
I always thought that Brother Maori was the God of Death, but now it seems that it is you, Conan-kun, who should go to the temple to worship! "
He looked up to the sky and sighed, his helplessness and speechlessness written on his face.
Conan: "..."
"Ahhhhh." Chun Riling couldn't hold back on the spot and let out a silver bell-like laugh.
Conan: "..."
The words damage +1 seemed to be emerging from the top of his head.
He glanced at Xiaolan Yuanzi's expression.
As expected, it was even more embarrassing.
I can’t stand it, someone is bullying a primary school student!
With a dark look on his face, Conan resentfully threw the ten-yuan coin he had been holding tightly in his hand into the small sink filled with water.
"Look, you can see the ten-dollar coin I threw in sinking to the bottom of the sink, right?"
"Yes." Xiaolan nodded and made a soft nasal sound.
"But if you turn the water glass over and cover it with the ten-dollar coin while there is still air inside." Conan did this.
"!
! "
"Disappeared...disappeared!"
Xiaolan and others saw with their own eyes that the coins sinking at the bottom of the sink disappeared immediately when the transparent cup was covered.
】
"Conan, you are so disgusting~" Chun Riling leaned down, nodded and leaned forward, her fair cheeks almost touching her, her throat tightened slightly and she spoke softly.
Her eyebrows and eyes curved into a crescent arc, shining brightly like stars.
A blush suddenly appeared on Conan's face, and his head subconsciously turned to the side. Joy appeared in his nervous heart, mixed with a touch of embarrassment.
Nahana, when she praises people like this, why does she think of Yu Yu Zhan's strange anger at that time?
!
"That's it! It's amazing!" Xiaolan said with a smile.
Conan's lips moved, and he organized his words to escape from the embarrassment, "This is just what Sister Nahua taught me. I think Sister Xiaolan, you should have also learned this principle, right?"
"Yeah?"
Xiaolan was startled and smiled awkwardly.
Sonoko even dodged her eyes and murmured in her heart, aren't the courses at Ekoda High School and Tedan High School the same?
Sera Masumi tilted his head, "The same principle applies to Officer Takagi just now.
Just now, he was in the tank that was upside down in the swimming pool and there was still air, so we couldn't see him in the swimming pool. "
Officer Memu stood up straight. He was suddenly startled, and out of the corner of his eye he caught sight of the coins in the small sink.
"Huh? It's strange, but you can see it from directly above."
"Yes, if you look at the interface between air and water from a position with a relatively small incident angle, it will not be in a mirror-like state." Kasuga Ling said calmly.
Sera Majun Heitan added, "But this is a swimming pool, so you can't look down from directly above, right?"
Officer Memu nodded and replied calmly, "That's true."
Chunri Ling's beautiful eyes were wandering as she looked at the people in front of her and spoke eloquently.
"In other words, the prisoner first let Miss Yongmei, who was alone here looking for the necklace, drown.
Then use the prepared sink to cover the body that sank to the bottom of the swimming pool, and then use fishing lines tied to the drains on both sides of the swimming pool to fix the sink.
Then just tilt the water tank slightly, put your hand into the water tank, release the air from Miss Nagami's oxygen tank, and fill the water tank with air.
After all, the fishing line is stretchable, so tilting the sink slightly shouldn't be a problem. "
Officer Megure nodded and asked, "But how did the prisoner let her drown?"
"It's very simple. Just say something to distract her who was in the swimming pool at the time, then grab her neck from behind, remove the respirator and press her into the water until she drowns." Masumi Sera used her best words. Tell the facts in a relaxed tone.
Chun Riling smiled and hummed helplessly.
"After all, Miss Yongmei is still carrying an oxygen tank and heavy objects, and with one person holding her down, it would be impossible for even an adult man to come out of the water to breathe.
Also, you can’t shout for help in the water, nor can you attract the attention of other passers-by.
am I right? Hotel manager, Mr. Toshima! The culprit is you! "
In an instant.
Everyone's eyes were fixed on Manager Toshima who was standing behind in shock.
Sera looked at the other party innocently and said coldly, "The way to make her relax is to stand in the swimming pool and point to her feet, and then lie to her that the necklace is there!
That should be it. "
"But, is it possible to fix the water tank with just a fishing line?" Officer Megure frowned and asked repeatedly.
Sera Masumi then explained: "..."
Chun Riling looked at the case that had almost been solved and had no intention of interfering with it anymore.
She felt a little tasteless in her mouth, so she bought a Yaketian lollipop from the system mall.
Seeing that the wrapping paper was so tight that she couldn't open it with both hands, she immediately used her trump card.
The red lips parted lightly, the white teeth bit the wrapping paper, and pulled it open.
However.
She only nibbled off a little of the wrapping paper, and the rest of the wrapping paper was still tightly attached to the candy.
Kasuga Ling: "..."
