Chapter 22. Valentine's Day (Part 22)
The crime scene is a private room on the second floor, from which you can clearly see the layout of the first floor. The deceased died of poisoning, but the key tableware was not contaminated with poison. Now we need to know how the other party poisoned him.

"The method of poisoning, huh? It was that couple." Conan looked at Rawl and the other man standing aside.

When Raw turned to the police, the phone was facing him. In addition, the screen of the smart phone was large and Raw did not deliberately block it, so Conan saw the conversation between Raw and Gin, but he was a little confused, as if the other party was deliberately showing it to him.

"Gin, Gin, damn it, he is actually a member of the organization. But why, was he exposed on purpose?" Conan didn't care about the case and doubts anymore. He just put his glasses to the maximum to peek at Roll's screen and watched all his conversations.

"hennessy? Hennessy, a French brand of wine, launches unique wines based on the tastes of different consumers. Is he a researcher of the organization? Speaking of which, he uses a mobile phone that has never been seen before." Conan silently recorded Rawl's information.

Hearing the conversation between the two, they actually wanted to solve the case quickly and leave, which made him a little embarrassed. As a detective, he naturally hoped that the case would be solved, but as Conan, he didn't want to let Raw and the others leave.

Without caring about the method of poisoning, Conan quickly ran to the first floor and approached Rawl and the other man.

Conan had a clear target and pointed directly at the two of them. Rawl was a little confused. Although he had his reasons for luring them, why hadn't the people in the organization discovered such a bold person?

"Conan, don't run around." Xiaolan quickly picked up Conan and stopped him from getting close to Raw and the others.

"As expected of the Koi Girl, I feel that the reason why Conan was not discovered is due to the other party." After thinking about this, Raw no longer wasted time.

"Student Xiao Luo, please help me find all the information about the deceased Hiraga Genji." Luo Er said into the phone.

"This will infringe on other people's privacy, do you want to continue?"

"Ah."

Soon, all the information about the deceased appeared on the mobile phone. All the traces that could be found on the Internet were presented to Luo Er.

"He actually booked three rooms, and there are three numbers with which he frequently contacts. They should be different people. This guy is actually having three affairs at the same time." Luo Er complained while looking at the records.

"Valentine's Day became the last straw that broke the camel's back," said Miyano Shiho, leaning in to take a closer look.

Luo Er thought that the other party was too bold to do this in the world of science. You have to know that in this world, trivial matters can become motives. This guy directly maxed out the buffs.

"Officer Megure, I already know who the murderer is." Raw walked directly up to the police and spoke.

"What? So fast, you are a detective?" Inspector Megure was a little shocked. They haven't even finished investigating the scene, but they already know the murderer?
"No, I'm a researcher." Luo Er introduced himself.

"It's indeed a researcher. What was that just now?" Conan was very concerned about this.

"Gao Chengpingmei, you must be the murderer." Luo Er looked at a woman who looked weak.

"Ah, I, could I be mistaken?"

"Genji Hiraga, he's your boyfriend. I'm not wrong, am I?"

Gao Chengpingmei hesitated for a moment and said, "Well, but do you have to conclude that I am the murderer because of this?"

"Brother, to identify the murderer, we still need evidence." Inspector Megure walked over and said.

Luo Er just said to himself: "Besides you, Hiraga Genji has two girlfriends. He even booked three rooms today, Valentine's Day. You have enough motivation."

"How do you know he has two girlfriends? Are you his friend?" Gao Chengpingmei's face darkened.

Officer Megure said earnestly: "Brother, let's talk about evidence. Since you and the deceased knew each other, the case should not be closed in this way."

"Genji Hiraga promised you that he would break up with them, but in fact he didn't. Because you were submissive, you have forgiven him for cheating on you several times. But you just can't accept that you have to share a man with other women on Valentine's Day, so you bought hydrogen cyanide. Do you need me to tell you the purchase address?" Raw still ignored Inspector Megure.

"He was the one who didn't keep his promise. I have forgiven him so many times. Why is this still happening? I just got trapped. What's wrong with me?" The woman knelt on the ground and broke down crying, confessing everything.

"Men won't cherish your forgiveness. They will only think that cheating is cheap and become more unscrupulous. Anyway, as long as you apologize and make a verbal promise, you can be forgiven. It doesn't take much, right?" Luo Er squatted in front of the woman and whispered. "Is that so?" The woman was like a walking corpse.

"Can you provide me with your saliva?" Luo Er took out a test tube.

Everyone was stunned by Luo Er's behavior. First he solved the case quickly, and then he asked for someone else's saliva? It was incomprehensible.

"It's like this. I've been studying love recently. I want to observe the hormonal changes in the bodies of people who are in love or have been heartbroken. It would be even better if you could provide blood." Luo Er explained seriously.

Miyano Shiho was speechless. When it came to biology, Roll was not good at it.

"Studying love." Conan's eyes turned into bean-shaped.

"Love?" The police officers were shocked.

"Yes, based on the changes in hormones in the body, we can determine a person's relationship status and judge love in the form of data."

"Well, it's not right to use data in love." Xiaolan said softly.

"This lady must have someone she likes." Luo Er said with a smile.

Conan looked at Rawl with a wary look on his face.

"No, no." Xiaolan retorted subconsciously.

"Hey, hey, hey, please be respectful. This is a murder scene, not a love research institute." Inspector Megure couldn't help but interrupt.

"Really? Aren't you curious? You care about whether he was fooling you when he told you that he was going to handle a very difficult case." Luo Er asked.

"Shinichi is not that kind of person." Xiaolan said firmly.

"Have you ever met again?" Luo Er continued to ask.

"There was a case before and Shinichi appeared there." Xiaolan replied, recalling the incident.

"Sister Xiaolan, you've fallen into his trap. Let's go home quickly." Conan acted cute and didn't intend to let Xiaolan continue to contact him.

"Did he leave in a hurry, but with someone covering for him and without taking his clothes with him?"

After hearing what Luo Er said, Xiaolan stopped. To be honest, there were indeed many unreasonable things at the beginning. Why couldn't they catch up with him just a few doors away, and no one outside had seen him?

All we have is Conan's message, which is mixed with too many doubts.

"Conan..." Xiaolan couldn't help but look at Conan.

"No." Conan interrupted quickly.

Xiaolan understood, although she didn't know why, but Conan was afraid that she would doubt him in front of this man. In that case, then she should go home and Conan would tell her the truth.

Looking at the two people leaving, Miyano Shiho analyzed: "Love can also reduce one's intelligence. I didn't even suspect why you knew it so clearly."

"It's fun, right? This is part of the fun. Let's go too." Luo Er took the initiative to pull Miyano Shiho's hand and walked out.

Leaving behind a confused policeman and the murderer who didn't know whether he should confess.

After that, the two did not encounter any more murders. Instead, they went shopping and watched movies together. They would hug each other when the atmosphere was lively. They believed that this was a way to collect data for research.
