Conan: About the fact that I have a black brother

"Thank you for your hard work, doctor." Qiuyue Zhengzou walked over, "Please take care of my daughter." As he said that, he took out a card from his pocket and tried to put it into the doctor's hand.

The doctor quickly refused: "Please don't do this, this is what we should do. Qiuyue Porcelain is a typical case of drug poisoning, but we can't tell which drug it is. If the family can provide possible sources of the drug, it will be helpful for our follow-up treatment. I have other patients, so I'll leave now."

Akizuki Zhengzou quickly agreed. Akizuki Michiyo had already taken out her mobile phone to start recording. Lin Xiaochen leaned over to take a look inconspicuously and found that the memo on the mobile phone was full of Chinese characters, and the count box showed 1033.

When I looked at the content, it turned out to be the recipes of the past few days and all the objects that Qiuyueci could touch at home.

Lin Xiaochen was dumbfounded. With this level of control, if he had not witnessed with his own eyes how intimate Qiu Yueci was with her mother, Lin Xiaochen would have suspected that she was being controlled.

But when he carefully recalled the chat records he found in Qiu Yueci's mobile phone, it was indeed Qiu Yueci who started the conversation first.

He sighed and could only say that the ways mothers and daughters get along with each other are diverse.

"How did you take care of the child? How did he get poisoned for no reason?" Qiuyue Zhengzou frowned, his face full of dissatisfaction and blame, and asked in a stern tone.

"How did I take care of him?" When Akizuki Michiyo heard this, she was immediately furious and thought it was ridiculous. She retorted,

"How did I take care of her? Wait until your daughter wakes up and ask her yourself! Okay, I really don't want to argue with you now. Please shut up and stop talking. Let's talk about everything after your daughter wakes up."

After saying this, Akizuki Michiyo turned around and walked quickly towards the ICU. From the look of her, she probably wanted to see her daughter who was still in a coma through the window glass.

"You are simply unreasonable!" Seeing this, Akizuki Zhengzou became more and more angry. He widened his eyes, glared at Akizuki Michiyo, and opened his mouth as if he wanted to argue with her loudly.

However, when he noticed Lin Xiaochen standing beside him, he suddenly seemed to remember something and swallowed back the words that were about to come out of his mouth. He changed his tone to a gentler one and said to Lin Xiaochen, "Thank you for making this special trip."

Lin Xiaochen raised his wrist to check the time, then said, "That's as it should be. If you have any new information or clues, please feel free to contact me."

As he spoke, he took out an exquisite business card from his pocket and handed it to the other party.

Qiuyue Zhengzou took it politely and lowered his head to carefully read the information on it.

When he saw the word "Patrol", he couldn't help but murmured softly: "...Patrol?" He seemed a little curious about the title.

Lin Xiaochen noticed Qiuyue Zhengzou's reaction, but did not explain much. He kept a professional smile, raised his voice slightly and said, "Well, I won't bother you for now." Then he nodded to Qiuyue Zhengzou to say goodbye.

At eight o'clock in the morning, the sun shines on the entrance of the police station. All the police officers are dressed in neat suits and are ready to go. Their goal is to investigate the Qiuyue porcelain poisoning incident, and they are divided into two groups to carry out the work.

Lin Xiaochen will go to the university to investigate with Zhufu Gaoming and two other police officers; while Yamato Gansuke will lead another team to Qiuyue's house to collect more clues.

Before leaving, Yamato Gansuke gave Zhufu Gaoming a provocative smile: "Would you like to compete to see who can find out the poison first?"

Zhu Fu Gaoming's eyes flashed with an imperceptible light, and he responded without hesitation: "I am most happy to do so."

Several people separated from each other.

In the school monitoring room,

Several police officers were responsible for the surveillance video of an area respectively, and the object of observation was naturally Qiuyueci.

Fortunately, Qiu Yueci is used to a life with a very regular schedule, so the police only need to find a specific time area to observe.

"Stop the video in the third row and fourth column." Zhu Fu Gaoming was the first to stop it. He frowned slightly and stared at the water cup picked up by Qiu Yueci in the picture. "Rewind the video 30 minutes."

The clever police officers assisted Zhu Fu and did as they were told.

Zhu Fu Gaoming looked at the empty area around the water cup and slowly relaxed his brows.

"Stop, the first column of the fourth row and the second column of the third row stop. The former will go back fifteen minutes and the latter will go back half an hour." Lin Xiaochen unconsciously clenched his fingers and leaned forward slightly.

The picture in the fourth row is the picture of the staircase on the third floor of the library, which can just capture Qiu Yueci's back and the hazy table top. The picture in the third row and second column is the surveillance camera of the library's tea room.

Lin Xiaochen carefully observed the thermos cup in Qiu Yueci's hand, as if he wanted to find a hole in it.

The color and size are obviously the same, but Lin Xiaochen found it strange.

However, the resolution of the video was too low, and Lin Xiaochen found it difficult to see the specific details.

He sighed, "Keep playing."

As time passed, the atmosphere in the monitoring room gradually became stagnant. Some people could no longer bear the high-intensity information input and began to become restless.

Lin Xiaochen raised his hand to wipe the sweat off his forehead, clicked on a few videos, and pointed out the time points one by one: "Here, stop again. With the lower left corner as the origin, (1,1) (3,2) (4,3) all go back one hour and fifteen minutes, (2,1) (3,4) (3,7) go back eighteen minutes, and enlarge them all."

Lin Xiaochen gave instructions calmly and the technicians executed them quickly.

The characters in the video flashed by like lightning, and the images on the screen kept switching. At the same time, the front of the tea room, the front and left sides of the stairs on the third floor of the library, and the front and side of the door of the study room on the second floor were gradually enlarged.

In these enlarged images, a figure wearing a black jacket and a denim cap is clearly visible.

What is strange is that this person has empty hands and is not carrying anything.

Lin Xiaochen frowned tightly and thought to himself: "There is still one thing missing..."

At this moment, Zhu Fu Gaoming's eyes lit up, and he pointed his finger at the (1,5) position at the top of the screen and shouted, "Fast forward the video in the first row, fifth column by nine minutes!"

As soon as the words fell, the screen flashed and the mysterious man appeared again. However, this time, he actually had a mint green thermos cup in his hand!

As the key scenes appeared, the whole incident seemed to become more and more confusing, but it also gradually connected the originally scattered clues into a line. Lin Xiaochen stared at the screen, quickly analyzing the scene in front of him in his mind.

Zhu Fu Gao Ming said: "It seems we have found someone."
