Looking at the red light lit outside the emergency room, Bai yanzhenyu secretly clenched his fist and asked Li Shanlu, who had experienced the whole thing: "Miss Li Shan, please tell us about the previous things in detail."

"Well, when I went to receive the mail this morning, I found a gift for the teacher... Then the teacher fell down poisoned and was sent to the emergency room."

Lishanlu wiped away the tears from her eyes, told the story in detail, and handed a poisonous chocolate she had brought to Baiyan Zhenyu and others.

Baiyan Zhenyu took the chocolate, put it in front of his nose and sniffed it gently. He smelled a smell similar to pyrethrum.

In a case solved before, Bai Yan Zhenyu acquired the intermediate [poison making] skill. With the help of relevant knowledge, he had a clear understanding in his heart. If there is no accident, it should be a pyrethroid pesticide.

Looking at Maori xiaowulang's look of being in a state of panic, Bai yanzhenyu comforted: "uncle, the thing smeared on the chocolate is just some ordinary pesticide. In addition, she has been treated in time. My aunt should not be in danger."

"That's good, that's good..."

Maori xiaowulang did not doubt Bai Yan Zhenyu's judgment, and secretly rejoiced. Fortunately, the perpetrator did not use highly toxic cyanide, otherwise he might be separated from Fei Yingli forever.

Half an hour later, the display light in the emergency room suddenly flickered, from red representing the progress of the operation to emerald green representing the end of the operation.

Seeing the attending doctor and several nurses coming out of it, Maori xiaowulang hurried forward, grabbed the attending doctor's arm and asked, "doctor, how's my wife?"

The attending doctor has long been used to such a scene. He didn't blame Maori xiaowulang for his impoliteness. After taking off the mask on his face, he said with a light smile: "don't worry, we have cleaned her stomach and there is no life-threatening. However, for the sake of caution, it's better to be hospitalized for observation today."

"Hoo, great, doctor. It's really hard for you."

After hearing the news that Fei Yingli was out of danger, Mao xiaowulang was relieved. His heart, which he had been carrying, was finally put down and quickly bowed to the attending doctor to express his thanks.

The white bird police officer who came to the scene after receiving the alarm asked the attending doctor, "doctor, is Ms. Fei Yingli food poisoning?"

The attending doctor nodded slightly and replied, "yes, it should be poisoning caused by eating some pesticide by mistake."

As soon as the attending doctor's voice fell, two nurses pushed an operating bed out of the emergency room. On it lay Fei Yingli, who was pale.

At this time, Fei Yingli had regained consciousness, but her body became very weak under the double toss of toxin and gastric lavage. She changed the image of strong women in the past and gave people a feeling of ill beauty like Lin Daiyu in the dream of Red Mansions.

Looking at Fei Yingli's weak appearance, Bai yanzhenyu flashed a cold light at the bottom of his eyes and had sentenced the murderer to death in his heart.

After Xiaolan and Lishan green sent Fei Yingli back to the ward for rest, Mao Li xiaowulang's face became gloomy and analyzed: "first, the Mumu police department was attacked by crossbows, and now Yingli was poisoned. I don't think it's a coincidence."

White bird police officer agreed with Maori xiaowulang's guess and asked the police responsible for investigating the scene: "excuse me, did Ms. Fei Yingli fall down immediately after eating chocolate?"

"Yes, yes, I heard it was put in her company mailbox." the policeman nodded and took out the wrapping paper left at the scene.

"Jikeba chocolate, and a flower made of paper..."

Baiyan Zhenyu moved in his heart, carefully looked at the white paper flower, and then reminded: "officer white bird, do you think this paper flower is the same as the paper sword, which is the information deliberately left by the prisoner to us?"

"It's really possible to hear you say that." officer white bird fell into meditation. After a few seconds, he looked up and said, "is the murderer the same person?"

Baiyan Zhenyu nodded and said slowly, "it's very possible, and even if it's not the same person, there must be some connection between the two."

Fei Yingli needs a rest, so Xiaolan and Li Shanlu have come out of the ward. After hearing the conversation, they asked, "mom has always been a very cautious person. Why do you easily eat something of unknown origin?"

"Xiao Lan, did you forget? When I had dinner with my aunt yesterday, my uncle and aunt talked about jikeba chocolate, and then my uncle made my aunt angry..."

Baiyan Zhenyu glanced at Maori xiaowulang with a smiling face and continued to explain: "I think my aunt probably took this gift as an apology gift given to her by her uncle today, so she would eat it without precaution."

After listening to Bai Yan Zhenyu's reasoning, Conan had a flash of inspiration, keenly perceived a new clue, and quickly said, "wait, the killer can know aunt Yingli's preferences, which shows that the killer knows aunt Yingli very well, and is likely to be an acquaintance of Uncle Maori or aunt Yingli."

"Eh?"

Maori Kouro said with a light sigh and some surprised approval: "Conan is right. Except for our two acquaintances, others don't know that Yingli likes to eat this brand of chocolate."

"OK, I'll send someone to investigate."

White bird police officer led the team to leave, while Bai Yan Zhenyu and others stayed in the hospital to take care of Fei Yingli to avoid any accidents.

At noon, Bai yanzhenyu returned to Maori office and cooked a pot of light stomach nourishing medicine for Fei Yingli.

Of course, Baiyan Zhenyu didn't forget Maori Kogoro and brought them a delicious meal.

The tempting aroma of the food filled the ward. Even Fei Yingli, who had no appetite, was greatly stimulated by the aroma and ate up a small pot of medicinal food prepared by Bai Yan Zhenyu for her.

In the evening, Fei Yingli's body had completely stabilized. Xiao Lan stayed in the ward to accompany and protect Fei Yingli. Bai Yan Zhenyu and others left the hospital and returned to the office to rest.

The next day, Bai yanzhenyu and Maori xiaowulang went to the police to help solve the case, while Conan went to Dr. Ali's house to cooperate with ash yuanai for regular inspection.

However, shortly after Bai yanzhenyu and Maori xiaowulang arrived at the police station, Conan called and said that Dr. Ali was attacked by a crossbow and arrow at home and was now sent to Mihua Central Hospital for treatment.

By the time they got there, Dr. Ali had left the operating room and was lying on the hospital bed chatting with the Mumu police department.
