At this moment, they suddenly heard a scream from the front of the plane.

"It's dead!" Such a scream came.

"Stop, stop," Qianyu's reaction was quick, and immediately grabbed Haibara Ai's hand that was hammering towards the ribs and the hand that pinched the back of his neck, and gently stopped him. "It seems that something happened ahead."

...

When Chiayu and Haibara Ai ran to the front of the plane, they saw a scene of laughter and crying - the body in the maki tree was lying on the ground, while Shindo Kou next to him tried his best to stop the passengers from approaching the maki tree to check her condition.

"Listen to me!" Shindo explained. "She was poisoned to death on the plane. She just didn't make any public announcement to avoid frightening you. You can ask the flight attendant!"

"She is right!" The flight attendant who finally slid down from the plane ran over and said. "Easy to evacuate quickly! The nose of the plane may have caught fire. Please leave here with me first!"

...

"The difference in arteriovenous oxygen content is 2.7%," said the flight attendant who was waiting for the inspection report of the two captains after the doctor at New Chitose Airport completed the examination. "In light of the content of your report, we suspect it was cyanide poisoning."

Poor arteriovenous oxygen content means the difference between the oxygen content of the artery and vein. Generally, this data should be about 4% (16% of the artery and 12% of the vein), and if this number is as small as 2.7%, it generally means that the patient's tissues cannot draw nutrients from the artery blood, which is a typical symptom of cyanide poisoning.

So, what does the two captains have to do with cyanide poisoning and the herds who died of cyanide poisoning?

"Well, can I ask?" The flight attendant finally hesitated and asked. "If it was a hand in hand, is it possible to get poisoned?" (This was also reminded by the doctor on the plane. The flight attendant finally realized what he was suspicious of.)

"Back with your own hands?" the doctor replied after a moment of frightening. "Unless the back of your hands is poisoned, it is unlikely."

"The back of the hand?" The flight attendant looked at one of his hands. "In other words, as long as the hand is poisoned, it is possible that the person who kissed the back of the hand may be poisoned?"

"It's possible," the doctor nodded. "Do you... know what?"

"..." The flight attendant hesitated for a moment, then nodded. "It's possible."

...

About twenty minutes later, the police had arrived and began to record every person present. But at this moment...

"Mr. Police," said the doctor on the plane after completing the transcript. "I hope you can hear my opinion on this case - I mean the idea of ​​the way of murder."

"What does it mean?" The policeman who recorded the transcript was stunned and looked at him suspiciously. "Do you have any opinions?"

"We've checked, both captains had mild symptoms of cyanide poisoning, and Miss Makiri happened to die of cyanide poisoning - this is obviously related, isn't it?"

"Do you know what the secret is?" the policeman frowned.

"The flight attendant said that she saw two captains kissing the back of the hand of the lady in the grazing tree - if the back of the hand is stained with cyanide, it can explain the current situation."

"What then?" the policeman asked immediately. "Do you find any signs?"

"We found cyanide and found it in many places," the doctor glanced at the flight attendant who had come over beside him and said. "The flight attendant and the doctors here can also testify."

"The two captains had residual cyanide on their lips, and Miss Makiri's tongue tip, lips and nose wings, and the cyanide content on the nose wings was very high." The flight attendant nodded. "So we hope you can immediately search Miss Sakai Natsuki who was applying makeup, and search her foundation before she could destroy the evidence."

...

"Didn't I say it? I don't know!" Sakai Natsuki frowned and retorted. "I don't know what happened at all! And don't you think you should ask the agent lady instead of me?"

"We have plenty of staff, so we can ask one by one," the policeman said slowly with his pen. "And this time it was a murder case, so we must be as cautious as possible."

Meanwhile, outside.

"Have you not found it yet?" Haibara Ai stood around the corner and looked at the airport transcript room not far away.

"No," Chiho frowned as he cleverly flipped over Sakai Natsuki's package. "I saw other cosmetics, but I just couldn't find the foundation - would it be on her?"

"Impossible, there is no space," Haibara Ai denied. "It's impossible for her to hide the foundation on her body in that way."

"If she throws it away, it will be a big trouble," Qian Yu sighed. "If that happens, the garbage may have been cleaned up, and it will be a big deal if you think about it."

"What are you doing?" At this moment, Conan's voice suddenly came, and he walked over with an envelope in his hand.

"Uh..." Qianyu, who was rummaging through Natsuki Sakai's bag, was a little embarrassed. "We are..."

"Are you planning to find Natsuki Sakai's foundation?" Conan said in one sentence and revealed the thoughts of Chia and Ai Haibara. "Is it right?"

"Ah..." Qian Yu nodded embarrassedly. "Yes..."

"It's okay," Conan shook the envelope in his hand with a smug look that could not be concealed. "But it seems that I'm just one step faster, I've found it."

"Inside..." Qian Yu looked at the bulging envelope. "Is this foundation-frost?"

"Yes," Conan highlighted the outline of the box of the foundation cream by pressing the envelope, and then nodded. "I did the same thing as you before, and then found nothing, so I initially inferred that Sakai Natsuki might have thrown away the foundation, so I retrieved the surveillance video to see her whereabouts. Then I guessed that although Miss Sakai Natsuki hadn't thrown anything, she had gone to the mailing point while going to the toilet alone, so I guessed that she might have sent the foundation to somewhere, so I went to the post office center to find a way to get the letter back."
