The young and beautiful female forensic doctor Du wore a mask. The hands that had dissected more than 100 corpses looked extremely soft in the crystal clear gloves, making it hard to imagine that these hands were specifically doing the job of dealing with the corpses.

He skillfully cut open the head teacher's stomach and found a large number of sleeping pills inside. "These solids!" Du Mingming opened his eyes wide and stared at the scene in surprise, "There are so many sleeping pills that have not been absorbed!"

Some form solutions in gastric juice, and some mix with gastric juice into a paste, and nothing else is there.

Du Mingming was very confused. Could it be... the head teacher took a dose of far more than thirty pills? If he only took thirty pills, based on the amount remaining in the stomach, it was visually measured that the amount absorbed was impossible to kill. However, the record of the black cold noodles was clearly that thirty pills were missing from the sleeping pill bottle around the head teacher.

Take out all the solid and liquid mixture in the stomach, concentrate and evaporate it to dryness, weigh out the mass, and then subtract the mass range of gastric acid that may contain, which is about twenty-eight tablets of this sleeping pill. That is to say, the head teacher's body only absorbs two tablets of sleeping pills. However, for this type of sleeping pill, taking two tablets of sleeping pills will not die at all.

I checked the blood again and found that the components of the sleeping pills in it were not enough to destroy the central brain system.

The deceased's brain nerve center was tested, and it was indeed caused by excessive sleeping pills to cause serious damage to the nervous system. Du Mingming fell into deep doubts: "Strange, why is the cause of death due to sleeping pills?"

The next day, Du Mingming handed over the report to Hei Leng Noodles and told about the phenomenon he discovered yesterday: "This is the specific situation."

Hei Leng Man touched his chin and frowned: "It's weird, since that's the case, how did he die?"

"However, the test found that he did die of excessive nervous system suppression. This is indeed the result of sleeping pills."

"It's strange, there's obvious contradiction. The head teacher died of sleeping pill poisoning, but the thirty sleeping pills he took were only absorbed about two of them, which was not enough to make him die."

Du Mingming shook his head: "Anyway, my work has been completed, and the next thing is your reasoning. Look forward to you, Lord God Police."

After walking a few steps, she turned her head and walked towards Hei Lengmeng, and took out a big one from the pocket of her bulging gray coat: "By the way, I found a sleeping sleeping station the day before yesterday, with a lot of garbage and sludge stained on it. I was worried that this was related to the case, so I put it in a plastic sealed bag."

In the evening, all the colleagues got off work, leaving only Zhang Wuji alone. Hei Leng Noodles came back with the bottle of medicine given by Du Mingming.

Zhang Wuji pushed the hot instant noodles over: "Lao Hei, it's the third time. If you don't eat it, the noodles will become more and more disgusting."

Hei Cold Noodles snatched the instant noodles and ate them voraciously: "No, I think the noodles that have been soaked for a long time will be even more delicious."

"Your taste is really unique. But I advise you to eat it, and don't let me heat it up even if it gets cold. Because when I first soaked it, I accidentally threw a corner of the plastic bag in. I was worried that heating the instant noodles again and again will make the plastic produce more toxins. If you are not careful, it will be bad for your health if you continue to be exhausted for a long time."

Hei Lengmian suddenly opened his eyes wide: "For years?"

"Yes, why, what's the idea coming up with you?"

Hei Leng Noodles carefully observed the bottle, and his eyes emitted a strange light. He hurriedly called Du Mingming: "Doctor Du! You just said that you took ten sleeping pills from this brand.

Although the five tablets are overdose, they will not cause death?”

"Yes, is there any problem?" Du Mingming asked in confusion.

Hei Lengmian almost gritted his teeth: "Thank you for your reminder, Dr. Du, I will sort out the incident clearly and verify the fingerprints on the sleeping pill bottle, so that the head teacher will not die in vain." After that, he hung up the phone immediately.

"Hey, hey?" Dr. Du pouted, "Why is it still so strange? You haven't finished speaking. Humph, I'm so angry!"

Heileng faced Zhang Wuji and said excitedly: "I suddenly thought that the reason why the head teacher died was because of the accumulation of sleeping pills over the years."

"But, taking sleeping pills for a long time will not happen."

"Have you heard of partial differential reasoning?"

"I haven't heard of it~"

"The head teacher must have taken sleeping pills for a while before. And the murderer must have a way to make sleeping pills work continuously in the head teacher's brain."

"Hmph, the essence of partial differential reasoning is that there is more than one cumulative factor! If we only start with one factor, we will definitely not find the method of committing the crime and the murderer; but if we can find other cumulative factors, we will definitely find the truth!"

"The sleeping pills that the head teacher has taken before will damage the central nervous system every time, and if the sleeping pills are taken by another substance, the central nervous system will be damaged every time. If the number of times is too many, there will be problems with the central nervous system."

"How long ago did the head teacher start taking the medicine?"

"He has an empty bottle at home, but if he takes the normal dose every day, it should be fourteen months. In fact, under normal circumstances, the period of taking a sleeping pill should not exceed fourteen days. Fourteen months has exceeded the use time, which has had a very bad impact on his body."

"But the factor that affects his body is by no means taking sleeping pills for two months."

"What would that be?"

"It is to take it twice as much as possible, and this time must be less than fourteen months. In this case, x and y will be used. x is the time to take sleeping pills, and y is the amount taken each time. Finally, z is the time of death of the head teacher!"

"Even if this is the case, it cannot be said that he killed it!"

"Look at the empty bottle of this sleeping pill."

Zhang Wuji observed carefully and found no strange things.

"You look at the amount you take. If you use the total amount to take each dose, see how many you get."

"520 divided by 30, fourteen... Oh my God, the dose above is actually 30 pills per day. Even if it is a newly developed drug, it should not be taken so many at one time."

"So, all the empty bottles have been labeled. Under normal circumstances, this medicine is taken for fourteen months. So, the head teacher overdoses sleeping pills and takes them for two weeks."

"So, he ate thirty pieces in the lounge because..."

"The bottle in the lounge was contaminated by ink, so the head teacher still took it according to the previous method. The murderer was worried that we found that she had changed the label, so she would contaminate all the labels with ink. In this way, the head teacher would take the medicine at a dose of 30 tablets, and it was difficult for us to suspect that the labels were changed when investigating the case. This new sleeping pill will not cause death if you take 30 tablets at a time. However, this medicine is newly developed and has not been promoted. The murderer believes that when we investigate the case, we will take it as a normal sleeping pill for granted. After taking 30 tablets, we will die soon, so we will not continue to investigate. This is the murderer's idea.

”

"However, the murderer did not expect that he would meet someone like you who is obsessed with reasoning."

"Who prepared this medicine for him?"

"His wife."

Kura Kana had a faint smile on her face. Her stepfather, who had once thrown away cruelly, finally disappeared in this world. Now she can finally be with her mother. The dusk in front was like a new sunrise, so full of hope. When her mother saw her, she would definitely be very excited. When she thought of this, she couldn't help but speed up and said to herself: Mother's surname is Mori, so I can change her name to Mori Kana. It's such a nice name.

Immersed in the happiness of imagination, a harsh voice that disgusted me came over.

"Master Kana! Please don't walk so fast, I, I can't walk anymore." Jingtian followed Kura Kana tightly, panting, and his eyebrows were full of flattery and pleasing.

Kurakana rolled her eyes loudly: "Who told you three to go fight again? You can't beat them and show off your strength. Look at your face, purple and purple. How can I let my mother see you later? You'd better go back. Also, don't call me lord!"

"No, Lord Kana, I am your flower protector, I will always be with you."

Kurakana curled her lips and did not look at Jingtian. She thought this shocking and could not be shaken off. If she really made a fuss, she might suffer from their campus violence, so she just said lightly: "Then it's up to you." But she kept thinking in her heart: It's so annoying, the leader of this stupid trio team will be arrested for fighting.

Jingtian continued to lick the smiling face and followed the goddess like a pug.

Soon he walked to the door. Kurakana was about to knock on the door, but two police cars came behind him. His smile froze instantly, and a vague feeling of uneasiness spread in his heart.

"Sir Kana, don't worry, there will be no problem." Jingtian tried to comfort him.

But looking at the solemn expression on the policeman's face, Kana knew that his stepfather's death was not simple, and it was very likely that his mother had been involved, and even... Kana didn't dare to think further. She trembled slightly beside her shoulders, held her hands in front of her chest, bit her lips tightly, and her heart couldn't stop trembling, staring at the people who were planning to enter her house.

Mom, don't have anything to do! Kura Kana suddenly thought that his mother might not kill his stepfather. Could it be that his mother had something to do with her stepfather? Thinking of this, Kana ran forward and asked the policeman who rang the doorbell anxiously.

"Uncle, what happened to this family?"

Hei Cold-Men stared at Kurakana's face professionally, observed her psychology, and found that the female high school student was very frightened. He suddenly thought that when he was investigating the Ban family, he found that the reorganized family had lost two daughters in a year eight years ago, one was Mr. Ban's biological daughter, twelve years old, and the other was Mrs. Ban's biological daughter, eight years old.

Seeing the nervous look of the high school girl, Hei Lengmeng couldn't help but suspect that she was the daughter of Mrs. Class who had been missing for many years.

Hei Lengmian could not tell the girl in front of him about the method and evidence of Mrs. Ban's murder. He just said lightly: "Come in, say anything quickly."
