"What did you say?!

The poison was formed in the victim's body?! "

In the small conference room, after listening to Tang Yuxin's report, Yu Jingren's eyes widened in disbelief. Although she knew that it might be rude, she couldn't care less at the moment.

"Yes, Prosecutor Yu. Don't get too excited. This is not impossible," Tang Yuxin walked over and pushed Yu Jingren back to her seat, patting her shoulder to comfort her.

"Prosecutor Tang, you mean that the poison was neither accidentally eaten by the victim, nor was it deliberately killed by someone, but that she accidentally ate something she shouldn't have?" Hwang Sun-beom obviously also found it unbelievable. Synthesizing chemical elements in the human body?

High-tech, it's simply …

"Yes, let's take a look."

As she spoke, Tang Yuxin fastened some papers and photos on the whiteboard with a magnet and continued, "I just went to the forensic institute, and I got a positive answer from them. Yoo Seon-hee's health is indeed not very good. In addition to malnutrition and bleeding gums, her quality of sleep is also very poor. Look here."

Tang Yuxin placed a magnified X-ray film of the corpse in the center of the whiteboard and continued, "Do you see the victim's spine? It's slightly curved here. It may be difficult to see it like this. I also took a normal one, so you can compare it."

After that, Tang Yuxin took another X-ray film from her stack of documents and fastened it on the whiteboard. Officer Huang and Dong-man, who were far away, stood up and walked to the whiteboard to take a closer look.

After a while, Choi Dong-man pointed to the spine on the X-ray film and said, "Although there is a curvature, relatively speaking, Yoo Seon-hee's curvature is a little bigger. Does she have slight symptoms of rickets?"

"As expected of an analyst, your sensitivity level is higher."

Tang Yuxin gave him a thumbs up and said, "Dong-man is right. Although it's very slight, there are already signs of rickets.

Malnutrition and lack of sleep are all factors that lead to a vitamin imbalance in the body. Bleeding gums and rickets are manifestations of a lack of vitamin C in the body. "

"Vitamin C deficiency?

Ah!

Is that why vitamin C was found in the victim's home? "Dong-man remembered the medicine bottle that Min Tae-yeon asked him to identify.

"Yes, the victim Yoo Seon-hee is between an ordinary vitamin C deficiency patient and a severe vitamin C deficiency patient."

"What's the difference between these two cases?"

Min Taiyan, who had been silent all this while, finally spoke. It wasn't that he wasn't paying attention, but that he had been observing Tang Yushen.

He felt that the current Tang Yuxin was a little different from before.

In the past, she played a guiding role in solving cases. Now, she seemed to have started to rely on the power of the team. Min Tae-yeon could see her frowning as she studied the data. He could also see her unusually focused expression when she was investigating. Although it was not that she was not focused in the past, there was still a slight difference compared to now.

These were almost impossible to see in the past.

In the past, when she gave out clues, it was as if she was saying something that she already knew. Although it was not very forceful, it gave people the feeling that 'this is the case. As long as we investigate this way, the case will be closed.'

Now, her tone was more probing, more thoughtful, and a little uncertain, but faintly revealed a strong sense of confidence.

Min Tae-yeon was right beside her, watching her change. Little by little, it made Min Tae-yeon feel that Tang Yuxin was starting to become real. She started to feel that she really belonged to the team and was no longer just a guiding role.

Why?

What was the reason for her to have such a change?

Originally, he thought that now that both of them had become vampires, he could better understand her as a person. Who would have thought that before the mystery of the past was solved, a new mystery was born?

He could not figure it out … He could not figure it out at all …

"Prosecutor Min?

Prosecutor Min?! "After explaining the difference between the two, Tang Yuxin realized that Prosecutor Min was actually in a daze.

"What?"

Hearing the shout, Min Tae-yeon's eyes focused blankly. What he saw was Tang Yuxin's puzzled and slightly reproachful expression.

"Do you understand what I'm saying?" Tang Yuxin asked again. Obviously, she was a little dissatisfied with Min Tae-yeon's absent-mindedness.

"What?" Min Tae-yeon repeated his rhetorical question.

"Please … I'm having a hard time explaining …" Tang Yuxin showed a helpless expression.

"Okay, I already know the difference between the two. The former is just a normal elemental deficiency, while the latter is listed in the category of diseases, right?"

Min Tae-yeon quickly summarized some of the words he had just heard and gave Tang Yuxin an answer.

"Mhmm, that's more like it." Tang Yuxin showed an expression of "You've passed this time" and walked back to the whiteboard.

"Is vitamin C the cause of Yoo Seon-hee's death?" Yu Jingren raised her head that was lowered for some unknown reason and asked Tang Yuxin.

"It's only part of the reason."

"Part of the reason?

Is Yoo Seon-hee really dying because of vitamin C?

How is that possible? There are many people in this world who take vitamins. "Hwang Sun-beom could not figure it out.

"That's why I said it's only part of the reason.

The other part is these. "As she spoke, Tang Yuxin placed some seafood photos on the table.

"Seafood?" Yu Jingren frowned and pouted. Her face was full of disbelief.

"Yes, seafood." Tang Yuxin nodded affirmatively at Yu Jingren.

"You mean, vitamin C and seafood caused this incident?" Min Tae-yeon followed Tang Yuxin's train of thought and came to this conclusion.

"Yes, the real culprits are these two." Tang Yuxin smiled and confirmed Prosecutor Min's guess.

"Seafood and vitamin C?

Culprits? "Choi Dong-man frowned and turned his head. His face was full of confusion.

"Yes." Tang Yuxin cleared the whiteboard to reveal a large blank space. Then she picked up a thick black pen and wrote while saying, "Seafood contains rich elements, including something called arsenic pentoxide."

After Tang Yuxin finished speaking, she wrote down arsenic pentoxide on the whiteboard, and then wrote the words' As2O5 'below it.

"Is this thing poisonous?" Officer Huang pointed to the whiteboard and asked.

"There are traces of toxins, but it doesn't have much effect on the human body."

After Tang Yuxin finished speaking, she wrote a plus sign on the whiteboard, followed by the words' C6H8O6 ', and then drew an equal sign.

"What is this?" Yu Jingren pointed to the new English letters and Arabic numbers and asked.

"It should be the molecular formula of vitamin C." Min Tae-yeon glanced at Tang Yuxin and said.

“bingo！

Correct answer! "Tang Yuxin smiled and clapped her hands, congratulating Prosecutor Min for answering the question correctly.

"Continue." Prosecutor Min had an interested look on his face as he let Tang Yuxin complete the formula.

So this time, Tang Yuxin completed the formula without stopping: 2C6H8O6 + As2O5 = As2O3 + 2C6H6O6 + 2H2O.

"This is the root cause of Yoo Seon-hee's death." Tang Yuxin circled As2O3 with a pen.

"Oh … so complicated …" Choi Dong-man facepalmed.

“As2O3？

Arsenic? "Yu Jingren confirmed again.

"Yes, As2O3, chemical name arsenic arsenic anhydride, also known as arsenic anhydride, commonly known as arsenic. It is a type of poison.

Ah, poison refers to a toxic substance that can cause cell denaturation in most organs of the human body. "

Tang Yuxin explained the poison to everyone, and then said, "This poison will paralyze the human capillaries, inhibit the activity of mercaptase, and cause liver lipid to become necrotic. The heart, liver, kidney, and intestines will become congested, epithelial cells will become necrotic, and capillaries will become dilated.

Therefore, the deceased will bleed from all orifices after death. "

"So, Yoo Seon-hee died because he accidentally ate these two things at the same time?" Min Tae-yeon confirmed with Tang Yuxin again.

"Yes, that's right."

"Aiyo, what's going on?

Yoo Seon-hee had to take vitamin C treatment because of his body, and the landlord aunt just happened to send so much seafood over at this time … "Officer Huang patted his head with his hand and shook his chair back and forth.

"Is this an accident?

How do we close the case?

Or do we transfer it to another department? "Yu Jingren looked at everyone and asked.

Everyone looked at each other, and finally focused their attention on Prosecutor Min.

Prosecutor Min lowered his head and thought for a moment, and finally said, "I'll ask Minister Zhang tomorrow, then we'll talk about it later.

It's a little late now, so everyone should go back and rest. "

"Okay then …" Hwang Sun-beom looked up at his watch and realized that it was already 9: 30 at night. Anyway, the case was almost finished, and he felt that this decision was not bad …

Obviously, everyone also felt that this was a good idea. For the past two days, the English alphabet and Arabic numerals in their heads were enough to give them a headache. Finally, the case was finally finished. Although the time taken was relatively short, it was the most frustrating case they had ever worked on. It was even more complicated than the group blind date …

"The two of you are going to Boss Luo's place?"

After everyone left, Hwang Sun-beom purposely stayed behind to talk to Tang Yuxin and Min Tae-yeon, who were also behind.

"Don't you want to eat?"

Min Tae-yeon replied faintly. Then, she saw Tang Yuxin frown when she heard the word "eat."

"Then I'll go with you. We can have a drink together."

Officer Huang looked up at the time and felt that it was still early. No one was waiting for him to go home, so it might be a good choice to be a third wheel.

"Okay, let's go together."

Min Tae-yeon nodded without thinking. She looked back at Tang Yuxin and found that the latter was still sitting there, thinking about something.

"Prosecutor Tang, if you don't leave now, Prosecutor Min and I will leave." Hwang Sun-beom squinted and walked over, teasing her.

"Okay, let's go, let's all go. We can go to the notarization.

It's good to be a witness for the two of you and officiate at your wedding. "Tang Yuxin came back to her senses and nodded seriously after hearing Officer Huang's words.

"…"

"…"

The journey to the bar was unusually quiet. Even after arriving at the bar, Tang Yuxin just smiled when she saw Boss Luo. Then, she walked into the private room prepared for them with a thoughtful expression.

"So late today?

There's a case? "

Boss Luo took out four wine glasses and poured wine for Hwang Sun-beom and himself. Then, he took out two bags of blood from the safe and filled the empty glasses in front of Min Tae-yeon and Tang Yuxin.

"Well, it's almost time to close the case." Min Tae-yeon picked up the wine glass in front of her and took a sip. Then, she let out a long sigh.

"Yuxin, what's wrong?

You don't want to drink? "Boss Luo turned his head to Tang Yuxin and found that Tang Yuxin did not touch her glass at all.

"Ah?

Oh … "Tang Yuxin heard him and took a sip from the glass. Then, she frowned hard." It tastes awful … "

"I just got this this morning. Why does it taste so awful after only one day?" Boss Luo picked up the glass and sniffed it. Then, he realized that he could not smell anything.

"She didn't eat breakfast today. She's still not used to frozen blood plasma." Min Tae-yeon sighed and looked worried.

"Do you want to give you another 200cc?"

Boss Luo asked tentatively. In the end, he saw a certain young vampire's eyes glowing brightly …

"Brother, we can't. If we continue to let her drink human blood, I'm afraid that one day, she won't be able to control her desires.

This morning, she almost revealed her vampire form in front of Yu Jingren because she was so close to Yu Jingren's neck. "Min Tae-yeon reached out to stop Boss Luo from holding the syringe.

"Tae-yeon, how did you control your desires at that time?" Hwang Sun-beom, who was sitting next to Boss Luo, asked after throwing a peanut into his mouth.

"At that time, my entire body and mind were occupied by hatred. I didn't have the time to pay attention to these things. After a while, I was able to tolerate it normally. However, the sudden close contact with her without any preparation caused the vampire in my body to become restless."

Min Tae-yeon looked at Tang Yuxin again with a worried expression. He found that the latter was still staring at the glass of frozen blood plasma and grimacing.

"Didn't you eat and drink blood plasma at Minister Zhang's place in the morning? Why can't you drink it now?"

Min Tae-yeon recalled that he had forcefully thrown Tang Yuxin to Zhang Zhewu's place in the morning. He had asked Big Boss Zhang to feed Tang Yuxin before releasing her.

"Minister Zhang forced that down my throat …" Tang Yuxin shuddered as she spoke.

"…"

"… Are you forcing us to use the same method?" Boss Luo said with a dark expression.

"Don't … You're abusing a rare animal …" Tang Yuxin leaned on the table and pretended to cry. Then, she raised her head and blinked her tearless eyes. She whispered, "Can you give me another 200cc?"

"Don't act cute, Prosecutor Tang!!"

Hwang Sun-beom could no longer hold it in. This woman was too ridiculous. He had never seen a vampire like her, but he had never seen a human like her either …

"Alright, since you've all said so."

Hearing this, Tang Yuxin straightened her body and leaned against the back of the sofa. She was in the same state of deep thought as she was in the conference room just now.

"What about dinner?"

Looking at the serious Tang Yuxin, Hwang Sun-beom thought that this girl had finally stopped acting. Seeing that the glass of blood in front of her was still untouched, he kindly reminded her.

"I'm not eating anymore."

"…"

"…"

"…"

This … She was completely in a fit of pique …

"I … I really have to hand it to you …" Hwang Sun-beom sighed in frustration.

"Yuxin, don't mess around."

Min Tae-yeon knew the pain of a vampire who wanted to drink blood but couldn't, so he wasn't too harsh on Tang Yuxin. However, since he was the one who changed her, he had to be responsible for her. It might be too early to be responsible for other things, but at least he should teach her how to eat …

"Then, Prosecutor Min, why don't you eat a piece of bread for me to see?!"

Tang Yuxin raised one of her eyebrows, clearly telling Min Tae-yeon that letting her drink frozen blood was as uncomfortable as letting a vampire eat human food.

"Tae-yeon, it's only 200cc, it's fine.

Last time, after I gave it to Yuxin, she didn't impulsively come over and suck me dry, right? "Boss Luo said as he took out a 200cc syringe from his arm and handed it to Tang Yuxin.

"That's right, that's right."

Tang Yuxin agreed as she took the syringe. Then, she picked up the syringe and looked at the color inside through the dim light in the private room. The blood-red color made her eyes blurry for a moment, and unknowingly, her pupils turned into a gem-like blue. Then, Tang Yuxin closed her dazzling eyes, sighed, and said, "Sigh, it's better not to suck it directly from the neck. I really envy Minister Zhang …"

Everyone: "…"

After drinking all the blood in the syringe in one go, Tang Yuxin let out a long sigh of relief, and a satisfied expression appeared on her face.

"Satisfied?" Min Tae-yeon raised one of his eyebrows and asked.

"Yes, satisfied.

The result of being satisfied is that I want to sleep, so let's go! "Tang Yuxin nodded happily, and was the first to stand up and walk towards the door of the private room.

So … this is the so-called … Not recognizing the big spoon after eating one's fill … Boss Luo thought sadly.

After leaving the private room and arriving at the bar's main hall, there were still many people dancing crazily on the dance floor. Young men and women were entangled on the dance floor, twisting their waists and venting their fiery passion.

In some dark corners, men and women were entangled together, kissing and caressing each other. What's more, some men had already reached their hands into the women's clothes.

"Girls nowadays, if they have money, they can go anywhere else. Why do they have to come to this kind of place?" Tang Yuxin lamented on the girls' lives as she walked.

"Not all of them are rich." Boss Luo paused for a moment before saying, "Some of them come here to sell their looks."

"Is that so? I rarely hear Boss Luo talk about your business here." After hearing Boss Luo's words, Tang Yuxin looked at Boss Luo meaningfully and said.

Boss Luo obviously understood what she meant. He smiled bitterly and said, "Don't look at me. I don't do this kind of business here. I only buy and sell alcohol. Those girls are all individuals, and they're not organized. They just unconsciously chose to come here."

After hearing that, Tang Yuxin nodded understandingly. Then, she looked at the bar counter and saw an extremely thin girl sitting there alone. Her head hung limply and her wrists hung unnaturally. There was nothing in front of her except for an empty wine glass.

"She's already like this, why isn't she treating herself better? She should at least order something to eat. No, this is a classic symptom of malnutrition. She doesn't even buy clothes for herself. How is she going to survive in the winter? She can't just rely on rich people's cars …" Tang Yuxin looked at the girl, shook her head, and sighed.

"Oh, you're talking about that girl. She just earned a sum of money yesterday, but her parents are addicted to gambling, so they probably sent the money back home.

She owes them money for that glass of alcohol. When she finds a suitable customer in the future, she'll pay them back. She's already so poor. She can afford not to buy clothes or eat food, but she has to drink alcohol. Her addiction to alcohol has become a habit. She can't kick it even if she wants to. "Boss Luo looked at her and shook his head.

"Gambling debt?" Tang Yuxin's eyes suddenly lit up after hearing Boss Luo's words.

"Yes, gambling debt." Boss Luo nodded confusedly to express his affirmation.

"Very poor? Can't eat?!" Tang Yuxin repeated Boss Luo's words.

"Yes, what's the problem?" Boss Luo nodded again.

"Winter?!

You don't have money to buy clothes? "Tang Yushen repeated what she had said before.

"Yuxin, what did you think of?"

In the end, Min Tae-yeon knew Tang Yuxin better. When he saw Tang Yuxin's expression, Min Tae-yeon felt that Tang Yuxin might have thought of something crucial to the case.

"Officer Huang, how much do you think Oh Young-ran's monthly rent is?"

Tang Yuxin didn't answer Min Tae-yeon's question. Instead, she suddenly turned her head to Hwang Sun-beom, giving him a fright.

"Two hundred thousand. What's wrong?" Hwang Sun-beom was also puzzled.

"Oh Young-ran still owes a huge amount of gambling debt?!

And it's increasing?! "Tang Yuxin asked again.

"Yes, I asked that casino. They said that she's a regular there. She occasionally wins a few rounds, but she always loses. She already owes a lot of money. If she doesn't pay it back on time, her organs will be removed and sold."

"That's right!"

Tang Yuxin suddenly clenched her right hand into a fist and smashed it into the palm of her left hand. "I was wondering why I felt that something was wrong!

So it's here! "

"What's wrong with my place?" Boss Luo was even more confused.

"No, no, no, I'm not talking about your place, Brother Luo. Your place is too good, it's too good!

It can't be any better!

Brother Luo, I love you so much! "After saying that, Tang Yuxin didn't care about everyone's astonishment and quickly ran out of the Blood.

club。

"Min Tae-yeon, I'm sorry, I really don't know anything …" Boss Luo tried to explain himself after a long time.
