The president changed his career to become a detective

Because how many things are sold from me, I can still get a commission.

Thinking this way, he felt much more comfortable.

　
He put this plate of food on Le Siling's table, turned around and wanted to leave.

But suddenly, Le Siling slammed down the table vigorously and said loudly: "Waiter! What did you do?!"

Ni Tengfei didn't know what was wrong, he turned around and looked at Le Siling with doubts on his face.Ni Tengfei didn't speak, not too much, waiting for Le Siling to speak.

Le Siling looked at Ni Tengfei with a puzzled face, and said, "Ni Tengfei! Is this how you work as a waiter? Just put a plate of food here, then turn around and leave, right?"

Ni Tengfei shrugged his shoulders, spread his hands, and then, with a slight smile, said, "Le Siling! What do you want?"

You got the things for you, my task has been completed, you won't want me to eat with you next time, will you?I will reject it!
When Ni Tengfei said this, Ni Ruonan and Leng Xuanang actually laughed.

Xing Yutong, Le Siling's classmate, also covered her mouth and laughed.However, Le Siling didn't smile, looking very unhappy.

Le Siling immediately raised her hand and said loudly: "Boss! You are not qualified as a waiter at all! How do you treat customers? You have no manners at all!"

After Rong Yuxin heard it, he had to come over.

In fact, Lao Rong Yu has been paying attention to this side all the time, and has been listening with his ears pricked up.It's just that he didn't expect that the little girl would call her over directly.

Rong Yuxin immediately walked over, looked at Le Siling with a smile on his face, bowed his head, and said, "Miss, what do you want?"

Le Siling pointed to Ni Tengfei who was standing next to him, and said loudly: "I don't think you are qualified as a waiter at all, I don't like it! Change to another!"

Rong Yu looked a little embarrassed, but still patiently looked at Le Siling with a smile all over his face.

She said, "Miss, what's wrong with you? Or did the waiter say something rude to you?"

Le Siling thought for a while, and finally found a reason.

She quickly said: "This waiter has a bad attitude!"

Rong Yuxin finally understood that this was the person who came here to find fault.

　Rong Yuxin seemed to realize something.

She immediately bowed her head and said, "Miss, how about it, how about I take care of your table myself? My waiter, who just came here, is really clumsy."

After finishing speaking, Rong Yuxin immediately turned his head and blinked at Ni Tengfei.Ni Tengfei was not happy at all, and immediately returned to the bar.

He was lying on the bar counter, looking at this side from time to time.

Rong Yuxin has been standing by the side to take care of the guests here.

The boss stood here, and Le Siling felt very uncomfortable again.

So she waved her hand, making Rong Yuxin leave too.

Rong Yuxin returned to the bar and said to Ni Tengfei: "You, sometimes you really have to change your temper. I think you will offend the guests by doing so."

Ni Tengfei was already full of anger, but now the boss criticized him indiscriminately.

Ni Tengfei straightened his face and said, "Boss, that's my classmate! We have conflicts, so she came here today to find fault."

Rong Yuxin had actually guessed a little bit earlier.

Because it is impossible for two strangers to be so funny to each other, you can tell by looking at the eyes that these two people actually know each other.

Rong Yu was not surprised at all, nodded and said nothing more.

After all, Ni Tengfei has resources.

Ni Tengfei works here, so he can bring a lot of classmates over for consumption. The most important thing is that Ni Tengfei now has a friend who is a policeman. Why not do it?
So no matter what the situation was, Rong Yuxin would never fire Ni Tengfei.

At this moment, although it was close to evening, it was relatively early for a place like a bar.What do you mean?

That is to say, now is not the time when the traffic is the most. On the contrary, there are very few customers now, and there are only a few people in the store.

Rong Yu kept looking at the door of the bar, hoping that more guests would come, and then he would feel at ease.

"what--"

She looked around, looked, looked, and suddenly heard someone shout.Rong Yuxin immediately looked over, the person who shouted was not someone else, but Le Siling.

Le Siling stood up in a panic: "Someone is coming soon! Dead! Dead!"

Rong Yuxin immediately ran over and found Xing Yutong lying on the table, foaming and debris at the mouth.

At this time, Ni Ruonan and Leng Xuanang also got up, walked over, and took a serious look at Xing Yutong.

At this time, Le Siling was already flustered and trembling, not knowing what to do next.

As for Rong Yuxin, his face was pale with fright, and he stood beside him, not knowing how to end it.

Ni Tengfei, on the other hand, walked over very calmly, and then sat next to Le Siling, looking very puzzled.

Ni Tengfei looked left and right, not knowing what this strange thing in front of him was called.

But he understands one thing, that is, a murder case happened under his nose, what does it mean?

It is possible that Xing Yutong died suddenly due to illness, or he was murdered.

Perhaps it was because his sister Ni Ruonan had handled too many cases, but he actually thought that this was probably a murder case.

Rong Yuxin was of course the person most responsible for dying in the bar.And as a waiter, he certainly has certain responsibilities.

The most important thing is - he brought the wine and food just now.

Everything that is eaten passes through his hands.

At the beginning, Ni Tengfei really felt nothing, but later on, he felt a little scared.

Especially when he saw Rong Yuxin frightened like that, he became more and more frightened.

He hurried over and grabbed his sister Ni Ruonan and said, "Sister, what should I do next?"

Ni Ruonan didn't say anything, just patted his younger brother on the shoulder, and then walked towards the deceased.

She knelt down next to the dead man, looking at the pale face of the dead man and the foam left by the mouth.

What is the situation here?

It was because the deceased had vomited.

Ni Ruonan felt that the deceased must have eaten something that made his stomach uncomfortable, so he vomited.

In addition, Ni Ruonan carefully looked at the traces on the ground.

She found that there were many traces of the deceased's footsteps on the ground, and these traces were very deep and disorderly, which meant that the deceased had struggled.

That is to say, the deceased was in great pain before dying.

So what can be so painful?

What is the situation that will make the stomach of the deceased uncomfortable?
Is it an acute illness?
What kind of disease is that?
If it is not a disease, it is that the deceased ate something that made his stomach very uncomfortable and nauseated. After that, he was very painful and suffocated.

What kind of situation is this?
Ni Ruonan stood up slowly and patted her head.

She couldn't remember what kind of situation it was.

She has also seen many cases, and she has seen many murder cases, but this is the first time she has seen this kind of case.

It's not a sunny day, but it's bright and clear, in a bar, in a public place like this, especially when there is surveillance, why does this happen?

And the girl didn't feel any discomfort before she came.

While Ni Ruonan was observing the situation of the deceased, Leng Xuanang had already contacted the police station.

The police came immediately, scouted the scene, and finally took away the deceased and what he had drunk.

The scene was secured.

Hearing that this happened, the boss's boyfriend Tang Hongshen immediately asked for leave and ran over.

When her boyfriend appeared in the bar, Rong Yu immediately felt a sense of security.

She ran over immediately and threw herself into the arms of her boyfriend.

The boyfriend hugged Rong Yuxin gently, and said, "Yuxin, don't be nervous. If someone murdered, the police will definitely be able to find the murderer. It has nothing to do with you or the bar."

Rong Yu was very grateful. He looked up at his boyfriend and said, "You don't suspect that the people in my shop poisoned me at all? You think someone murdered me, right?"

The boyfriend nodded and said, "Yu Xin, believe me, someone must have poisoned you. I believe that the police are wise and will definitely catch the murderer."

"Well, I trust Ni." Rong Yu felt much more relieved.

Tang Hongshen thought for a while and said, "Besides, if the deceased died of an acute illness, then it has nothing to do with our bar."

With the comfort of her boyfriend, and the fact that the existence of her boyfriend is a kind of reassurance, Rong Yu finally calmed down.

The autopsy report of the deceased Xing Yutong, as well as the wine glasses the deceased had drunk and the food he had eaten, were quickly detected.

The autopsy report showed that there was a chemical called sodium nitrite in the blood of the deceased.

In addition, this substance is also contained in the food eaten by the deceased.

In the wine glass of the dead, the same is true.

What does this mean?
Sodium nitrite is added to food and wine in bars.

It is normal for food to contain sodium nitrite. If the dosage is less than a certain level, there will be no problem.

However, if the dose of sodium nitrite is too high, there will be a risk of poisoning.

Although there is sodium nitrite in food, the dose is not enough to be fatal.

However, in the wine, the content of sodium nitrite is very high, enough to kill a person.

The dead will die from this glass of wine.

So the question is, who put sodium nitrite in the wine?

After Ni Ruonan learned about the autopsy report, she kept thinking about a question.

Why did the deceased drink this glass of wine?

Instead of Le Siling?

The first object of Ni Ruonan's doubts was actually Le Siling. Thinking of this, Ni Ruonan felt a little hard to speak, but she still spoke.

The girl turned her head, looked at her brother, and patted him on the shoulder.

Ni Ruonan said to his younger brother: "Tengfei, don't be nervous, I will definitely find out the murderer!"

I would do it even for you.

After Ni Ruonan finished speaking, she walked towards Le Siling who was sitting beside the table in a daze.

To be specific, Le Siling is not just in a daze, she has been thinking about the cause and effect of the whole thing.

She also looked a little sad in her heart.

Ni Ruonan walked over slowly. At the beginning, she didn't speak, but slowly sat down beside Le Siling.

Then Le Siling spoke first.

Le Siling looked a little unhappy and said, "Ni Ruonan, what do you mean?"

Are you looking at me like this?

Do I have anything to do with this case?

Ni Ruonan didn't understand.

What I care about now is the murderer of this case, and as a classmate——

The classmates who come to drink together can be regarded as friends, even if they are not friends, they are still very good classmates.

A classmate passed away, Le Siling, how could he still speak in such a thorny manner?

At this time, Le Siling shouldn't ask the detective.
