Hearing Tang Ze's words, everyone present was shocked.
Then everyone reacted immediately and realized what the "poison" Tangze was referring to.
"It seems you are all aware of it too."
Seeing everyone's different expressions, Karasawa smiled and said directly: "Yes, that special "poison" is the dry ice that Mr. Ayano used during his performance!
Although dry ice has been used by performers to create atmosphere on the stage for a long time because it is harmless and can smoke, the concentration of dry ice is less than one percent.
However, the composition of dry ice is the same as the carbon dioxide exhaled by our bodies. If the concentration increases, it is still dangerous.
The upper limit of this concentration is 20%. If it exceeds this concentration, the human body will be poisoned by carbon dioxide.
Not only that, the body will also suffer from severe convulsions, and death will occur within seconds.
Miss Yoko's tongue biting phenomenon is a special spasm caused by carbon dioxide poisoning.
And just now I deliberately took off my gloves to touch Ms. Yoko, just to confirm whether the temperature of the corpse was lower than the temperature of the corpse within 30 to 60 minutes of death under normal circumstances.
The answer is yes, so it can be determined that the prisoner poured high-concentration dry ice into the room to kill Miss Yoko!"
Tang Ze tapped his toes on the ground as he spoke: "Actually, this technique also requires a prerequisite, which is a very airtight room.
Otherwise, if it is a well-ventilated room, if Ms. Yoko opens it to sleep, this plan may not be successful.
But here, the success rate is 100%.
Because in order to prevent seawater from intruding and leaking, the cabin of the cruise ship will make the entire room very airtight.
Therefore, the carbon dioxide produced by dry ice has no way to escape from the room, so the concentration can easily reach the lethal dose of 20%."
After explaining the technique, Karasawa continued: "One of the things that can prove the murderer's conspiracy is the freezing temperature of Miss Yoko's body.
And the second is the fact that the bird is still alive.
Because carbon dioxide is heavier than air, it will only accumulate at the bottom of the room. The birdcage is hung much higher than the bed, so it naturally escapes.
But Ms. Yoko, who was sleeping on the bed, was obviously not so lucky. The height she was at happened to be in the area covered by carbon dioxide, so she was unfortunately killed."
"Then how did the murderer pass the dry ice to the lady's room?" Hanako couldn't help but ask.
"It's easy, just go through the keyhole."
Karasawa walked to the door of the room, smiled at Ayako who was standing at the door and listened, and then said: "You can touch and see, the keyhole of the room and the surrounding area are very cold.
In other words, the prisoner uses a thin tube to pass through the keyhole to send the carbon dioxide gas produced by the dry ice into the room.
It is precisely because of this that the temperature of the keyhole is extremely cold.
And you are the only one who uses dry ice on stage, Mr. Ayano.
I think as long as I check your room, you should be able to find the thin tube. After all, you didn't expect Miss Hanako to discover the body so quickly.
My girlfriend and I were already on the deck long before the crime occurred, so I'm sure you didn't have the chance to throw the crime tools into the sea.
There is a huge secret room under the ship. No matter how well you hide it, once the cruise ship docks and the Metropolitan Police conducts a carpet-like investigation, you will be able to find the key evidence."
"It turns out the murderer is you!"
Hanako excitedly rushed to Ryo Ayanokoji: "You are the one who keeps pestering my lady!
Because she doesn't accept your love, you kill her!"
"That's not the case, I don't love her at all!" Ayano Kojiliang said impatiently: "I'm not pestering her either!"
"Then why did you kill her?" Hanako asked crying.
"Yoko is a rich eldest lady with a willful and indulgent personality. She always wants to be the center of attention and get the attention of everyone to feel excited!"
When Ayano Koji Ryo heard Karasawa's words, he was already in despair, because he knew that what the other party said was right, and he would definitely not be able to run away.
Faced with Hanako's questioning, Ayano Koji Ryo also took off her guard and revealed everything like she was venting: "In the beginning, she was just an audience.
But then, for some reason, she suddenly realized that I was a little short on money, so she came to my door and asked me if she could sponsor me.
The only condition is that I want her to be the heroine on stage.
Later, she chased me all over the world. Over the past few years, she has been asking me to make her the center of attention.
But I don’t want to do this anymore, I can’t stand it anymore!!”
Ayano Koji Ryo roared excitedly: "I'm a first-class magician, so what's wrong with me wanting to express myself in my performance!
I don’t want others to influence my will. I just want to perform according to my own will. What’s wrong with me?
But she was unwilling to let me go, and threatened me that if I didn't continue to listen to him, she would completely ban me and prevent me from receiving commercial performances again.
Her family is very powerful, and no one is willing to offend her for a little magician.
I was like a bird in a birdcage, being played with by her constantly without any freedom."
Ayano Koji Ryo vented and gasped, "That's why I killed her!!"
"Do you think you can find the dignity of a magician by killing her!?"
After listening to Ayano Koji Ryo's motive for murder, Karasawa couldn't help but angrily yelled: "What you did is just destroying the reason you love most with your own hands!"
Hearing Karasawa's words, Ayano Koji Ryo could no longer stand, and fell to his knees in an ORZ manner. Following the routine procedure at the end of a case, he shed tears of regret.
After the case ended, the cruise ship docked at the Tokyo pier an hour later.
On the pier, the flashing red lights of the police cars were so dazzling.
"Police department, thank you for your hard work."
After getting off the boat, Karasawa saw Officer Megure coming towards him and greeted him with a smile.
"What a hard work I have done. The case was solved by you, brother Tangze."
Officer Memu waved his hand when he heard this: "Brother Tangze, you have to work even though you are on vacation, so it will be even harder."
"Well, fortunately it's the return trip, so it doesn't affect my mood."
Tang Ze waved his hand with a smile, and immediately handed the evidence in his hand to the other party: "This is the key evidence of the case. I will write a report on the specific process of the case and send it to you tomorrow."
"Thank you for your hard work." Officer Megure patted Tang Ze on the shoulder and immediately called his subordinates to receive the prisoner.
After that, Officer Megure arranged for a criminal to send Tangze and the two back home.
Ordinarily, Karasawa would definitely refuse, but this time the cruise ship canceled its itinerary for tomorrow morning due to the case, and docked directly at the pier, so no one came to pick them up.
So I can only take a taxi.
"I know Yoko likes to attract attention, but I really didn't expect that I would die because of it."
Ayako sighed a little and said: "If you don't want to cooperate anymore, why don't you just let him go? Given her family background, there are many magicians who are willing to let her shine."
"Maybe I don't care."
Tang Ze shook his head and said: "She is a rich young lady, and everyone around her surrounds her to please her.
So after hearing Ayano Koji Ryo's appeal, he didn't take it seriously at all and felt that he could handle it easily.
But she didn't know that a magician's dream is to stand on the stage and become the only focus.
In order to sell their dreams, they will suffer a lot.”
"It is precisely because you despise the things that others value that you will die."
Tang Ze shook his head and said: "Okay, don't feel bad, it's better not to know about these things behind the stage.
Speaking of which, you have made a great contribution this time.
To be honest, I almost missed this clue before. After all, I always wore gloves and the touch was blocked.
Fortunately, your words reminded me, and then I understood the key to the case.
What a great hero!"
"No way, that's just my nonsense." Ayako waved her hand in embarrassment: "It's just that you happened to think of it."
“Even when you have a flash of inspiration, you need to be prompted.”
Tang Ze smiled and said: "But without prompts, there will be no subsequent reasoning.
If we follow the reasoning in the movie, then you will play the role of "Watson" this time."
"That's too exaggerated." Ayako waved her hands repeatedly, but the smile on her face never stopped. It was obvious that she was able to help Karasawa in the case and was praised and affirmed by him, which felt very useful.
While chatting, everyone returned home.
After the case was over, Ayanokoji Ryo was handed over to the security personnel on the ship, so the two of them took a shower while they were free.
So after arriving home, the two of them went directly back to the house to rest.
Although this case was solved quickly, a murder will naturally make people feel exhausted. In addition, the schedule that was originally expected to go back tomorrow morning was suddenly changed to midnight, and I was already very sleepy.
However, before going to sleep, Tangze, who was thinking about the case rewards, first called up the system panel to check the case rewards this time.
[Case of female corpse with severed tongue]
completion; perfection
[Congratulations to the host for obtaining magic (5 years)]
Evaluation: In this case, with the reminder of your girlfriend, you successfully discovered the clues that you almost missed, but this was not because of your carelessness, but because of your rigor.
After this case, perhaps we will gain experience and avoid this kind of mistake again in the future.
Somehow, you have won the favor of fate!
Following usual practice, Tang Ze first read the evaluation of this case.
There is not much to say in this comment. Rather than being a criticism, it is more like a reminder to let him know that being rigorous is not a wrong thing, but he must also learn to pay attention to the shortcomings brought about by being rigorous.
Tang Ze also agrees with this point very much, and he also feels that this case has truly given him a lesson.
As for the temperature, you can't notice it when wearing gloves, but you can't ignore its existence.
Normally, there is no need to worry because forensic doctors have special measuring instruments.
But the situation at that time was that there were no forensic medicine and tools, so we had to pay more attention.
Overall, it was pretty good. This case also brought experience and growth to Tang Ze.
To be honest, at his level, a slight increase is already a very good improvement.
It is very difficult to just rely on people to teach these experiences. Only people who have real experience and are good at summarizing can organize and summarize this knowledge.
Obviously, this kind of very detailed knowledge is not taught in books, so Tang Ze only understands it after encountering it.
This is the advantage of actual combat, because you will encounter all kinds of things, all kinds of techniques and tricks.
There are always things you have never experienced.
And when you decipher its existence, it will turn into nutrients to feed back your own abilities.
Of course, this small improvement is nothing to Tang Ze now.
However, this reward is still a big improvement for him.
His B-level magic has now been directly upgraded to A-level [16/20], suddenly reaching the master level.
Although it is impossible to compare with the world's top magicians, it is more than enough to compare with the three on the cruise ship.
Another skill broke through to level A. Tang Ze nodded with satisfaction and immediately fell asleep.
A night of silence.
Tang Ze slept until after ten o'clock and then lazily got up.
After eating something casually with Ayako, the two of them didn't do anything else. They just lay on the sofa in the living room and defended themselves out of boredom.
They went out for more than 10 days and encountered another case on the last day. They were also a little tired.
This kind of fatigue is not due to fatigue from work, but simply because I am tired and want to relax.
They lay down until noon. After eating lunch cooked by Yonehara Sakurako, they lay down again.
I've been out for a long time some time ago, and I don't want to go out again after I get home.
The two finally decided to play games on TV and spent the day happily.
"Speaking of which, the next two days happen to be Saturdays and Sundays. We don't need to go to work. Can we just stay at home?"
After dinner, Ayako looked at Karasawa boredly and asked.
"Isn't there a movie screening this week? I'm quite interested in that movie." Tang Ze said with a smile, "I have nothing to do anyway, so you can go watch it with me."
"What movie?" Ayako asked curiously.
"'Red Shura Tengu', I saw the creator's stage play in college before on the Internet. I thought it was very good, so I asked your secretary to help me get two tickets for the premiere some time ago." Tangze said with a smile.
"Hearing what you said, I'm quite looking forward to it." Ayako smiled and said, "Then let's go and have a look tomorrow."
"OK."
Karasawa smiled and nodded. After resting for a while, he took Ayako and started doing yoga to digest food.
As soon as I closed my eyes and opened them again, the time had come to the critical Saturday.
After taking a lunch break, Tang Ze and the others drove to the movie premiere venue early.
During the premiere, the creative team became the absolute focus. Karasawa and the two acted as the audience in a low-key manner, quietly enjoying the story of the Edo period told by this movie.
