My Partner is Shiina Mashiro

"Then there is no need to explain too much." DR Fashion took out a small bottle from his arms, "I found this in the Sobu High Chemistry Laboratory, a bottle of ferrocyanide potassium chloride !"

"Ferrocyanide. Potassium...? Isn't that an additive in the experiment?"

Liu Sen was a little puzzled. Ferrocyanide and potassium chloride are sold on Taobao. This has something to do with poison... Wait!

Ferrocyanide. Potassium... Cyanide. Potassium? !

"DR fashion, you mean?!"

"Yes, Police Officer Liu, you are really smart." DR rubbed Liu Sen's thigh fashionablely, laughing non-stop, "Cyanide and potassium are the king of poisons. Normal people should not be able to get them. of."

Indeed, potassium cyanide is one of the fastest-acting known poisons, and ordinary people can't get it at all.

"Then these potassium cyanides should have appeared in that way."

"Yeah." DR Fashion nodded, "I was already curious when I tested the vomit yesterday, these cyanide potassium is very strange. The quality is not as good as the smuggled ones, but it is also self-made. It's too advanced."

"So, my guess is correct." Liu Sen raised his eyebrows, and threw away the bottle of ferrocyanide and potassium chloride in his hand, "Although this thing is only two words away from cyanide and potassium chloride, But the toxicity of ferrocyanide and potassium is far lower than that of cyanide and potassium. I remember that the common salt used for cooking has this thing—it seems to be antifreeze?"

"Completely correct!"

"Get up for me!"

Liu Sen kicked DR Fashion five meters away with a note of "Foshan Wuying Kick".

"In theory, as long as potassium ferrocyanide is burned, a mixture of potassium cyanide and iron carbide can be obtained, and then a little purification can be done."

"It's true that it's simple in theory, but in practice, it's safe to inhale cyanide gas when heating without certain professional knowledge. The corresponding equipment should not be available in a high school chemistry laboratory. ?”

Liu Sen frowned and looked at the medicine in his hand, and he began to feel a little puzzled in his heart.

Although all the evidence points to Yukinoshita Yukino as the murderer, according to the judgment of DR Fashion and his professional knowledge, it is impossible for a high school student to do the purification of ferrocyanide. Potassium after burning.

It's not that Liu Sen never thought that Yukino Yukino might use the power of the Yukinoshita family to purify it.But let’s not say that Yukinoshita Yukino hates borrowing the power of the family very much. Besides, they all borrow the power of the family, so why bother to carry out the purification work, and directly smuggle the perfect quality cyanide. Potassium. Yet?

From this point of view, if Yukinoshita Yukino is still not found in the future, then it is necessary to go to Yukinoshita's house.

Chapter 220 Who else is Yukinoshita Yukino?

From this point of view, it is necessary to go to Yukinoshita's house before Yukinoshita finds it.

Thinking of this, Liu Sen thought, before going to Yukino Yukino's house, he should walk around the campus of Sobu High now.Not to mention the cup of milk tea that was poisoned, just the chemical laboratory where ferrocyanide and potassium were stored was enough to attract his attention.

Saying hello to Mu Mu Shisan, Liu Sen was planning to take a stroll around the campus of Zongwu High School, but when he was about to leave, a slender but unexpectedly strong hand grabbed his lapel.

"truth?"

"Sen, eat first." Zhenbai said solemnly, and she put a box of lunch in Liu Sen's hand while speaking, "You are not allowed to work until you finish eating."

Zhenbai stared intently with a sullen little face, and Liu Sen knew that whenever Zhenbai showed this expression, he would not listen to anyone's opinion.

"I can't eat enough." Liu Sen couldn't laugh or cry, "I promise to go to work after eating."

Liu Sen randomly found a chair in the atrium and sat down. While eating, he sighed that his pet girl had also learned to take care of others.

From the original "Human Erha" to the current "Caring Little Padded Jacket", Zhenbai has also grown a lot when traveling around the world with Liu Sen.

The food in the box lunch was nothing special, but Liu Sen, who had a big mouthful of grilled rice, tasted very delicious.This is a real change of heart, no matter how you say it, you have to finish it.

Swallowing the boxed lunch into his mouth like a gulp, Liu Sen took the pure water that Zhenbai handed over in due course, and gulped down most of the bottle.

Wiping off the sweat from his head, Liu Sen, who was full of food and drink, was about to continue the investigation of the case, but just as he stood up straight, he found Hui Yuanai's eyes blinking and staring at him non-stop .

"Xiao Ai?" Liu Sen waved his hand in the direction of Hui Yuan Ai, "Are there rice grains stuck to the corner of my mouth?"

"No, no..." Hui Yuanai turned her head away in panic, her pretty face flushed with blush, "Brother Liu Sen, work harder!"

"I know, you and Zhenbai will wait for me obediently here."

The voice became softer, and the figure also faded away. After Liu Sen completely disappeared from sight, Hui Yuanai patted her own small chest.

It is said that men are the most handsome when they work hard and spend money seriously. Although I don’t know if this is a universal value, but at least Liu Sen, who is working hard for the case, falls in Hui Yuanai’s eyes, it is indeed glowing.

"Sen is a very serious person." Sitting gently beside Hui Yuan Ai, Zhen Bai, who took care of Liu Sen's diet, smiled softly, "If Xiao Ai has any troubles, you can tell them. I think Sen must be willing to help you solve it."

my troubles?

Hui Yuanai's complexion suddenly turned sour.She had witnessed the darkness and strength of the organization. If the three of Liu Sen were involved in the organization's incidents, they would probably be swallowed up to the point where there was nothing left.

Other than his parents and sister, it was the first time Liu Sen and the other three made Hui Yuan Ai feel the warmth of this world.

"The organization must be kept secret... As long as I don't tell, no one can find me."

In the bottom of her heart, she made up her mind that Hui Yuanai would never allow Liu Sen and the other three to be involved in the organization's incident because of herself. Now she has one and only one thought——

She just wants an ordinary, ordinary life.

......

"Is this the chemical laboratory of Zongwu High? Who broke the glass?"

"Hmph, I was beaten to death by Uncle." The sudden middle-aged male voice made Liu Sen turn his head, "Uncle Mao Li?"

Liu Sen is not surprised that Mori Kogoro will appear here, because Police Officer Megure also told him before that Mori Kogoro is also investigating on the campus of Sobu High.

"I didn't mean you, Uncle Mao Li." Liu Sen was a little puzzled, "Why did you break someone's glass for nothing?"

"Do you think I thought of it!"

"Uncle Maori broke the door forcibly because he couldn't find the key~"

Another voice came in, this immature voice and the iconic little blue suit—Conan, the little devil, ran around the murder scene again.

"Conan, when did you stinky brat sneak in?!"

Sure enough, as Liu Sen expected, after seeing Conan-kun who suddenly appeared, Kogoro Mori became very angry.

"No, Uncle Maury—look, what's that?"

The sharp-eyed Conan-kun seemed to have discovered something, and his voice immediately attracted the attention of Liu Sen and Mori Kogoro.

"Is this hair?"

Liu Sen, wearing white gloves, looked seriously at a strand of pink hair-like object on the slipway in front of the chemical laboratory.

"Whose hair is this?"

Liu Sen put the pink hair-like object under his nose and sniffed it.

"It smells like blood."

"What, is there blood stains on it?" Moori Kogoro, who was also wearing white gloves, moved his head to Liu Sen's hand, "If this is hair, it is unlikely to be a boy's hair based on the length of the hair Bar."

Pink hair, girl, and police officer Megure said that the person who reported the crime was a young female voice.

A figure flashed in Liu Sen's mind...just why did that guy appear here?

Sure enough, there is some value in visiting the campus of Zongwu High School.Although the subsequent search in the chemical laboratory did not reveal anything new, the discovery of this pink hair-like object was already considered somewhat rewarding.

"Then let's go to the milk tea shop next time."

Liu Sen took the lead and walked in the forefront.

"Let's go and investigate who bought that cup of highly toxic milk tea."

......

At one o'clock in the afternoon on the same day, the rest area of ​​Sobu Gao Milk Tea Shop.

Because it is a statutory holiday, the customers in the milk tea shop seem a little sparse, only a few couples like Lingding are throwing flash bombs as if no one else is there. From this point of view, this milk tea shop should be a holy place for couples to gather.

"If these young lovers know that this milk tea shop has sold milk tea that was used as a "murder weapon" for murder, can they still drink it?"

Liu Sen thought with some evil taste.

In fact, when he walked to the milk tea shop, Liu Sen had already blamed himself a little bit. If he could have paid more attention to whether Yukinoshita Yukino was holding milk tea in his hand, then the case would be clearer. ?

But now is not the time to feel sorry for himself. Liu Sen, who walked to the back kitchen, decisively took out his police ID card, and then the owner of the milk tea shop with a confused face was so frightened that he threw all the milk tea in his hand on the ground.

"Don't be nervous, we just came here to understand some issues." Liu Sen comforted the uneasy mood of the milk tea shop owner, "Did you sell such a cup of milk tea yesterday morning?"

"Yes, yes." Wiping the cold sweat off his brow, the owner of the milk tea shop stammered, "Here, this is our signature milk tea - White Lover."

"So do you remember who the person who bought this cup of milk tea is?"

"Um...let me think, let me think." The owner of the milk tea shop stomped his feet in panic, but the more nervous he was, the more confused his brain became.

"This police officer, please let me check the monitoring, because I was on holiday, I remember that I only sold a glass of White Lovers yesterday!"

The owner of the milk tea shop quickly tuned out the surveillance video, and he, who has always been careful in his work, has always had the habit of keeping consumption receipts.

According to the consumption receipt, the owner of the milk tea shop immediately determined the time period when "White Lover" was sold, and he adjusted the surveillance video to that time.

Liu Sen somewhat hoped to see the figures of Miura Yuiko and Hayama Hayato in the surveillance video, because that would more or less remove the suspicion of Yukinoshita Yukino.

It's just that many of the images fed back to him by the surveillance video have completely disappointed him.

That jet-black long hair, that cold and haughty face, apart from Sobu Gao's "Flower of High Ridge" Yukinoshita Yukino, there is no one else.

"Did Yukino buy it from Yukinoshita... I'm still investigating this. Hurry up and find a way to catch people."

While smiling wryly, Liu Sen shook his head.Except for the strange source of potassium cyanide and the mysterious caller, the evidence is sufficient to this extent.

If it weren't for the milk tea shop owner who seemed to have something to say, Liu Sen really didn't have the heart to continue the investigation.

"Comrade police officer, I remembered, I remember the situation yesterday like this."

The frowning milk tea shop owner thought seriously, and then told Liu Sen everything he saw and heard yesterday.

......

"Hehe...it feels a little cold. It's been raining recently, and it's chilly everywhere in the school."

"You are so fragile, you have never changed from before to now."

"Don't say that, Yukino, I'm not the crybaby I used to be, okay?"

"Really? Anyway, in my opinion, you have always looked like this from before to now."

"Hey...forget it, you haven't forgiven me anyway, have you?"

"Why should I forgive you? You should know better than anyone else what good things you have done yourself?"

"I said I really didn't mean to—hey, what's this?"

"Is this for me? Why are there two straws?"
