"Liu Ser, the autopsy report of Kang Mei came out, and from our physical examination of the deceased and the situation at the scene, the deceased ate or drank something containing trioxide kun, which caused the seven orifices to bleed and died."

Forensic Doctor Yang Yang stroked his thick glasses as he spoke.

"What trioxide, why can't I understand what you're saying?" Hearing Yang Yang forensic doctor say this, Huang Dou was at a loss for words he had never heard of.

"Brother Yimao, trioxide kun is also known as arsenic in our folk, I think you must have heard of this term in TV costume dramas!" Xiaowen on the side hurriedly popularized the relevant knowledge for soybeans.

"This kind of arsenic is colorless and tasteless, and it is normally a white frosty powder, so once you are poisoned, you will definitely die!"

Woman: "Arsenic? Our Wu Zhou Dynasty also often used arsenic to poison people to death, the death was tragic, now think about it, it is exactly the same as the death of the person called Kang Mei today! ”

Man: "Then who poisoned it, and why did you poison a person who eats and broadcasts?" ”

Woman: "Then who knows, it seems that we have to wait for them to investigate properly!" ”

"Then how long does it take for a person to eat this poison to death?" Huang Dou continued to ask curiously.

"It's not good, but if a normal person ingests more than three grams of arsenic, he will definitely die. As we can see from the mucosal extract from the stomach of the deceased, the deceased was able to suddenly feel unwell and die in a short period of time, and the amount of arsenic ingested at that time must have exceeded three grams! Yang Yang looked at the test report in his hand, and made an autopsy explanation for the deceased to Liu Ser and several others.

Hearing Yang Yang forensic doctor say this, Liu Ser suddenly fell into deep thought. "Looks like we're going to check out the back kitchen of Wonder Restaurant!" Liu Ser, who was talking, hurriedly waved his hand at the soybeans and a few people, signaling to hurry up.

"It's strange, the only people who competed with Kang Mei at that time were me and another player, after the two of us ate the hamburger, there was nothing wrong, but after the Kang Mei drank a big gulp of water, there was an abnormality, what is the problem here?" Huang Dou sat in the car driven by Brother Ping and said to himself.

Hearing Huang Dou say this, Xiaowen on the side couldn't help but nod and said, "Yes, when the game was in the game, that anti-sister was fine, why did she bleed and died after drinking water?" ”

"Well, it seems that the crux of the problem is likely to be on the glass of water that Sister Kang drank, after Sister Kang drank the water, I remember that the cup she put on the table was also gone, who got the cup at that time, we are likely to find the murderer who poisoned it!" Liu Ser said as he analyzed it seriously.

"Oh! Liu ser, I understand, what you mean is that only the person who was poisoned, after the anti-sister drank the water, was in a hurry to destroy the evidence, so he was in a hurry to take the cup! Huang Dou carefully followed Liu Ser's train of thought and analyzed.

"That's right, I'll go to the back kitchen with Xiaowen later, investigate the situation, Wang Yimao, you go to the monitoring room of Wonder Catering and see the surveillance video of the recording site at that time, who took the cup of water for my sister to drink!"

"Yes, Liu Ser!" Soybeans hurriedly responded. Watching the car turn through the bustling main road, find a parking space, stop, and several people quickly got out of the car and went to the Wonder Restaurant.

The manager of the Qiqu store, who was directing the cleaning in the store, couldn't help frowning when he saw Liu Ser and a few people coming again, stepped forward, and reluctantly squeezed out a smile and said, "Liu Ser, haven't we finished our transcripts before!" Why are you here again? ”

"We still have some things that we haven't investigated clearly, and we still need to go into the store to investigate, so it shouldn't delay your business, right?" Liu Ser knew that the other party did not welcome him, so he quickly said with a smile.

"Hey, Liu Ser, where are you talking about, you see, in the afternoon, I am still very lively here, but since that anti-sister died in my place, you can see again, where do I have a customer here who dares to come to me to eat!" Our boss said that it was really not possible, so we could only redecorate the store! ”

The manager of the Wonder Store who said this pouted and looked very sad.

"Hey, don't worry, maybe Sister Kang's death has nothing to do with the burgers in your store!" Liu Ser said comforting words to the manager.

"What, really? If that's the case, that's great, Liu Ser, do you already have a clue? If so, you should tell me as soon as possible, and we will fully cooperate with your work! The manager who was talking was obviously a little excited, and took Liu Ser's hand with tears in his eyes.

"Definitely, definitely, don't worry, I'll tell you when the time comes!" Liu Ser said as he instructed Huang Dou and Xiaowen to act according to their orders.

At this moment, in a corner, an employee in a restaurant quickly slipped away nervously through the back door after hearing the conversation between Liu Ser and the manager.

Together with Xiaowen, after checking the food and staff in the back kitchen, Liu Ser walked through the work itinerary of the kitchen staff today.

Huang Dou hurriedly followed Liu Ser's previous instructions, and with the help of the manager of Qiqu Catering, he successfully went to the monitoring room to check all the video details of his time when he ate hamburgers with his anti-sister competition.

Man: "Oh, when I watched the video of my ultimate burger competition, it felt so strange, you see, why my mouth is so big, I can stuff such a big burger in one bite, I can't bear to look at it!" ”

Female: "Nonsense, who pays attention to their personal image when they compete in eating!" Oops, don't you interrupt the soybeans, you didn't see that people were busy watching the video! Now the focus is on the anti-sister, stupid! ”

"Who makes your burgers here?" Liu Ser looked at the tableware in the kitchen and asked the manager who had been following him.

"Ao, it's our Master Wang, he is the master of our catering department, our boss spent a lot of money to invite him, Master Wang is honest and honest, and has been working with us for five or six years!"

The manager, who was talking, hurriedly beckoned Master Wang to come over and take a picture of Liu Ser.

"You're Master Wang?" Liu Ser stared at Master Wang next to him carefully, and felt that his behavior did reveal a sense of loyalty and honesty, so he couldn't help but continue to walk forward while asking.

"Yes, Liu Ser, I just went to take a note today!" As Master Wang spoke, he nodded at Liu Ser and said.

"Then all the burgers prepared for today's game, including the one eaten by the dead anti-sister, were you also made?"

"Yes, I did it!" Master Wang replied one by one.

"Who is the person who delivered the food to the game?" Liu Ser continued to ask.

"Oh! It's my son Xiao Wangzai, who gave me a hand and was responsible for delivering food to the front restaurant! Master Wang hurriedly agreed.
