In terms of interpersonal communication, Muyuan has always followed the principle of respecting other people's choices and not helping others make decisions.

This is the lesson he finally summed up in his previous life after seeing various cases of damaged heart circles, and it is the most important thing to ensure the harmony between people.

But now...... Mu Yuan felt that this principle had to be followed by an additional clause

- on the basis that the choices and decisions of the other party do not cause self-destruction.

How can there be a person in this world who drinks a clean drink in one gulp knowing that tea is poisonous?

Mu Yuan couldn't understand it, but ......

Sayuri Matsumoto is such a person.

Moreover, she is also the owner of a perfect heart circle, and Mu Yuan can't guess the true thoughts in his heart through the direction of the other party's gaze and the change of the heart circle like he did with Takasugi Toshihiko.

Looking at Sayuri Matsumoto, who was already unconscious in pain with a mouthful of blood lying on the carpet, the idea of not wanting to meet a perfect person was born in Mu Yuan's heart for the first time.

Sayuri Matsumoto, a dangerous person who will suddenly and unilaterally destroy the relationship he has built up with great difficulty, is better off not reaching out again.

Mu Yuan secretly made up his mind.

…

"The cans have signs of corrosion, and there are lacunar lesions in the mouth caused by burns, oh, blisters, and some hot cheeks...... The poison in lemon tea should be a strong alkali, suspected to be sodium hydroxide."

In the bridal lounge, Ash Yuan Ai immediately stopped Suzuki Sonoko from wanting to take mineral water and straws, and explained calmly:

"Rinsing with water will only exacerbate Matsumoto's injury, and vomiting will also cause secondary damage to the mucosa of the digestive tract."

"Huh?" Suzuki Sonoko froze on the spot and said worriedly, "So, what the hell should we do?"

"Sister Xiaolan, I remember that you have the milk you bought this morning in your bag, right?" Conan looked at Mu Yuan and said cutely, "Matsumoto ...... If my sister can't drink water, she should be able to drink milk, right?"

Gray Hara glanced at Conan, "The fat and protein in milk can react with sodium hydroxide, and it is true that it can dilute the sodium hydroxide that Miss Matsumoto drinks, but it is better to find some egg whites."

"I'll go to the kitchen!" Maoliran handed the milk to Gray Plains, and then hurried out the door.

Conan began to observe the traces in the house, and Makiyuan was helping Ashbara to support Sayuri Matsumoto's head, and for a while, only Suzuki Sonoko was left standing in place.

"That's, that'...... What can I do?" Suzuki Sonoko looked curiously at the Ai Gray Hara, who was rescuing, and asked in a low voice.

Ashbara was seriously feeding Sayuri Matsumoto milk, and Makito looked up at Suzuki Sonoko and said calmly, "If it's not troublesome, Sonoko, can you call an ambulance first, and then go and invite Officer Twilight and them in?"

"Oh, yes!" Suzuki Sonoko smashed her palm with her small fist, took out her mobile phone and turned around and ran out the door.

On the side, Conan, who had already circled the lounge, squinted his eyes and looked at Mu Yuan again, his eyes still full of scrutiny.

[There is no problem with Mu Yuan and the woman's rescue, and there is no intention of obstructing the arrival of the police, it seems that it ...... It's really not what they did, but ......]....

[How did he see that Matsumoto-sensei's lemon tea was poisonous?] 】

[If it is true that as he said, the person who poisoned it was Takasugi Toshihiko, and he had already told Matsumoto-sensei about the poison in the tea, how could Matsumoto-sensei ......]

"There is no doubt about it, Miss Matsumoto, that she did drink this cup of poisoned tea of her own free will."

Gray Yuan's cold voice suddenly sounded, interrupting Conan's train of thought.

Conan was slightly stunned, and then said, "Ah, how do you know Gray Yuan-san......

"Don't you understand the way she looks?" Without waiting for Conan's selling moe to finish casting the spell, Ashbara pointed to Sayuri Matsumoto's blood-soaked mouth and said coldly, "What she drank was sodium hydroxide!"

"Hydroxide...

Conan, who was obsessed with studying Mu Yuan's suspicions, finally came to his senses, and Tong Kong suddenly shrank and muttered, "Yes, that's sodium hydroxide!"

How could a conscious person swallow most of the sodium hydroxide solution in his stomach?

The burns and sharp pain from the first bite alone are enough to make people vomit out all the rest of the liquid, right?

When they came in just now, Sayuri Matsumoto was the only one in the lounge, and there was no trace of struggle and resistance on her body, so there was no other possibility than voluntarily.

There was no need for Mu Yuan to lie about whether he had told Matsumoto Sayuri that it was poisonous.

But if Mu Yuan didn't lie, why did Sayuri Matsumoto have to endure severe pain and drink this cup of poisonous tea?

Just as Conan was deep in thought, the sound of hurried footsteps from outside the door, 'Dongdong Dong...... also came from outside the door.

"Sayuri! How so...... Who the hell is it!?"

After rushing into the door and seeing the awakening in the room, Matsumoto Kiyocho's already fierce face suddenly became hideous.

He immediately looked at Mu Yuan beside his daughter, and wanted to ask, but suddenly remembered what Mu Yuan had said to him before.

"You know who did it, right?" Matsumoto Kiyocho forced himself to calm down, and asked Xiang Muyuan in a deep voice.

Makito ignored Matsumoto Kiyocho's inquiry, and just looked at Twilight Thirteen behind him, "Officer Twilight, can you please invite the groom, Mr. Takasugi Toshihiko, to the side of the lounge first?"

"Ah, Brother Muyuan......" Twilight Thirteen looked at her boss with some hesitation.

"Do as he says, Twilight." Matsumoto Kiyocho nodded silently, "The others stayed to protect the scene."

"Yes!"

…

The daughter of the former administrator of the search class was killed, and the wedding scene was soon blocked by the criminal police who were already sitting in the guest seat.

The ambulance arrived a little slower, but fortunately, Moriran found a large number of raw eggs from the pastry chef in the back kitchen, and under the guidance of Ashbara, he took out the egg whites and fed them to Sayuri Matsumoto.

By the time the paramedics lifted Sayuri Matsumoto into the ambulance, her brow was no longer as tightly knit as it had been at the beginning.

"Don't worry, Sheriff Matsumoto, as long as the oral sodium hydroxide solution is treated urgently, it is generally not life-threatening, Sister Sayuri has received the most timely treatment, she will be fine." ….

After seeing the ambulance leave, Gray Yuan looked at Matsumoto Kiyonaga with a fierce look in his eyes, and said softly.

Matsumoto Kiyocho was slightly stunned, looked down at the little girl beside him who had guided Mao Lilan throughout the rescue, and reluctantly squeezed out an ugly smile, "Little friend, you are really amazing, much better than us useless adults, Sayuri's thing...... Thank you very much!"

When the words fell, this tough guy sheriff, who was more than 1.8 meters tall, actually bowed to Gray Yuan Wai seriously.

"It's nothing, my uncle is a scientist, and that's what he taught me." Gray Yuan Ai turned his head calmly and tugged at Mu Yuan's robe, "Brother Mu Yuan......

Mu Yuan then took a step forward, "Sheriff Matsumoto, about Ling Ai's poisoning......

"Officer Twilight, Officer Twilight! The results from the forensic department have already come out, can you show me?"

Before Mu Yuan's words were finished, Conan's voice attracted the attention of Matsumoto Kiyocho, and Matsumoto Kiyocho immediately waved his hand, "I will definitely investigate this matter myself, and before that, please all the people who have entered the lounge cooperate with the police investigation!"

Mu Yuan frowned, hearing the suspicion and resistance in Matsumoto Kiyoshi's long words, so he had to temporarily put back what he wanted to say.

[At present, it is the most complete and best sound for listening to books, integrating 4 major speech synthesis engines, over 100 kinds of timbres, and it supports offline reading

Under the auspices of Thirteen, the officers of the Forensic Bureau then announced the results of their investigation.

It was the sodium hydroxide in the lemon tea that caused Sayuri Matsumoto's poisoning, and according to the video camera footage recorded by Moriran and Suzuki Sonoko left in the room, almost everyone who entered the bridal lounge had come into contact with the bottle of lemon tea, except for Ashbara, Conan, and Moriran.

And among all the people who have been exposed to lemon tea, the only thing that seems extremely abnormal is ...... The last shepherd is far away.

"Host Muyuan, how did you know that Takasugi poisoned Sayuri's tea?"

The footage of the video stopped, and as Matsumoto Kiyocho asked, everyone's eyes focused on Mu Yuan.

Matsumoto Kiyocho followed up and asked, "Since you've already told Sayuri about the poison in the tea, why did she ......?"

"Sheriff Matsumoto, can you let the officers in the house go out for a while?" Makito interrupted Matsumoto Kiyocho's words with a calm face, and said calmly, "I would like to ask Mr. Takasugi Toshihiko a few words alone."

"Ah......h Brother Muyuan, I'm afraid this won't work, after all, Takasugi Toshihiko's confession is still ......."

"Don't worry, you can leave this here." Mu Yuan waved his hand and pointed at the camera on the table.

"This ......," Twilight Thirteen looked inquiringly at Kiyocho Matsumoto.

Matsumoto Kiyoshi pondered for a moment, "Okay, our people can leave for a while, but you only have ten minutes, okay?"

"Enough." Mu Yuan smiled slightly.

Matsumoto Kiyoshi nodded, turned to look at the subordinates beside him, and said without hesitation, "Twilight, let people call up all the details that can be collected, about Takasugi Toshihiko and Makiyuan, I want to check it myself." ….

「…… Yes!" Twilight Thirteen nodded yes and shrugged his shoulders at Mu Yuan.

The implication is clear – he trusts his brother 100 per cent.

Mu Yuan smiled disappreciatively.

His identity is innocent, unless he can go to Tokyo Bay for a search lesson, he won't be able to find out the slightest clue.

Soon, the officers of the search section withdrew from the eucalyptus scene under the leadership of Twilight Thirteen, and Takasugi Toshihiko was also brought in by Takagi Wata.

Sonoko Suzuki and Moriran showed a fierce gaze the first time they saw Toshihiko Takasugi.

Under this invisible murderous aura, the innocence on Toshihiko Takasugi's face suddenly froze.

"Humph!" Suzuki Sonoko snorted coldly, gritted his teeth, and said, "Muyuan, Xiaolan and I are not from the police, we should be able to stay here, right?"

"Well, it doesn't matter." Mu Yuan nodded.

"Alright, Ran and I, as well as Conan and ...... Huh? What about Conan?" Suzuki Sonoko, who was about to gather his teammates to strengthen his momentum, was stunned for a moment, and looked around the room, but he didn't find Conan.

Maolilan soon noticed this, and a puzzled look appeared on his face.

Only Gray Yuan Ai rolled his eyes and said coldly, "I think he probably went to peek at the personal information of the person in front of him and Mu Yuan."

"What!?" Suzuki Sonoko crossed her waist and said dissatisfied, "This nasty little ghost, when you need him, you actually ran out to play by yourself?"

"Garden ......" Mao Lilan smiled wryly, looking at Mu Yuan and Gray Yuan Wai with a faint apology.

She knew that Mu Yuan's personal information within the police was definitely a temptation that Conan couldn't refuse.

"Forget it, it's pretty much the same with or without that little ghost anyway!" Sonoko Suzuki wiped her nose, glared in front of Takasugi Toshihiko, and asked loudly, "Say! Why are you harming Matsumoto-sensei!?"

"Huh? Garden...... I don't understand what you're saying, how can I ......" is also the heir to the foundation, and Toshihiko Takasugi has still seen Sonoko Suzuki.

"Mr. Takasugi, since the person you hate is Sheriff Matsumoto, why don't you just attack him?"

But before Takasugi Toshihiko's quibble was finished, Mu Yuan's calm tone was already ringing in the room.

"What!?" Several people showed surprised eyes, and Suzuki Sonoko said even more bluntly, "The reason why he poisoned Matsumoto-sensei was to get revenge on Sheriff Matsumoto?"

"Don't, don't be kidding......" The smile on Toshihiko Takasugi's face stiffened a little, and his gaze at Makito was a little dodgy, "I have hardly met Sheriff Matsumoto a few times, how can it be ......?"

"Oh? Is it because of a previous meeting?" Mu Yuan interrupted again, "When will we meet? A year ago, two years ago...... Twenty years ago, twenty years ago?"

In the face of Mu Yuan's somewhat chattering to himself, although Takasugi Toshihiko felt that something was not right, he did not feel too panicked, but when Mu Yuan accurately said the time of his mother's murder......

"You, you, you......"

Takasugi's eyes widened suddenly.

"What happened to your meeting with Sheriff Matsumoto twenty years ago?"

Mu Yuan ignored his reaction, and just continued to take care of himself:

"Did he do something to hurt you...... It doesn't look like you'......."

"That's what hurt someone close to you? It seems so...... Is it your friend? Close relatives? Is it your father? Mother? Is it Mother......

"You, how can it be, no, what are you talking nonsense!?" Takasugi Toshihiko pointed at Mu Yuan with a trembling finger, and the sweat on his forehead had already gathered into sweat droplets.

His clumsy quibbles can be seen through even by Suzuki Sonoko.

"Sheriff Matsumoto, did you really kill your mother?"

Mu Yuan's tone was as calm as ever, but Takasugi Toshihiko's eyes showed obvious panic.

Obviously, this question is to the point for him.

"In other words, Sheriff Matsumoto didn't actually kill your mother, so who is it......

"That's him! If it weren't for that bastard Matsumoto Kiyonagu, my mother would have survived!

！ At that time, as long as he was ......."

In the excited roar of Takasugi Toshihiko, the expressions of Mao Lilan and the others were completely calm.

They saw the most true appearance of the coward in the well-dressed groom in front of them.

The melon is not bowed
