Huo Yushen's news was as cold and cold as himself.

[Huo Yushen]: I'm here, you can come to the branch station immediately.

[Huo Yushen]: ?

Two messages were sent.

The time of the first message was 11 o'clock this morning.

The time of the second message was half past eleven this morning.

The interval in between was only half an hour.

Then came Meng Guanghui's news.

[Meng Guanghui]: When you first see you in Xia, what are you doing?! The chief is here, why don't you hurry over?

[Meng Guanghui]: See you for the first time in summer! You're going to get a demerit for that!

Meng Guanghui's two messages, at 11:10 a.m. and 11:40 a.m., happened to come out after Huo Yushen's two messages, obviously reminding her.

Xia Chujian suddenly had a headache.

She rubbed her temples, eager to rest for a day before replying.

But she also knows that now is not the time to be emotional, although she is still very uncomfortable and aggrieved.

So Xia Chujian first sent a message back to Meng Guanghui.

[See you at the beginning of summer]: Leader, I was so tired yesterday that I didn't get up until now after sleeping at 5 o'clock in the afternoon. I immediately sent a video call invitation to the chief.

then pulled out the virtual display screen of the quantum light brain and sent a video call invitation to Huo Yushen.

Huo Yushen quickly clicked through.

His face, as cold as the ice of the Far North, changed from virtual to real, appearing on the virtual display.

Xia Chujian also said with a cold face: "Inspector Huo, I was so tired yesterday that I slept until now at five o'clock in the afternoon. ”

Of course, Huo Yushen was not satisfied with Xia Chujian's attitude, but looking at Xia Chujian's expression, he was indeed very tired, he didn't say anything, but quickly asked, "Do you have anything to say to me about Yu Wang's death?" ”

Xia Chujian was silent for a while, she did have a lot to say, and she briefly mentioned it to Huo Yushen in the news that day, but she didn't expect him to be so attentive.

But she can't let others hear those words, not even her family.

What's more, there is also a robot with particularly long ears at home.

She asked tentatively, "...... Can it be encrypted with quantum entanglement? ”

Huo Yushen understood her concerns in seconds and nodded: "I'll encrypt it." ”

In this way, Xia Chujian is just passively accepting it, and it will not cause too much burden on her quantum light brain.

Soon, quantum entanglement encryption was done.

Huo Yushen said: "No one can hear us now. ”

Xia Chujian breathed a sigh of relief, and said solemnly: "I told Leader Meng about the judge organization and the Holy Maiden the day before yesterday, you should already know about it, right?" ”

Huo Yushen's face remained unchanged, and he replied without any personal emotion: "Well, Xiao Meng has already been to Fenghai City, where he destroyed several strongholds of the judge organization and arrested a large number of middle-level backbones of the judge organization. ”

Xia Chujian suddenly thought of what Yu Forgot to worry about what was written in the long essay of Xingbo, and asked in a low mood: "...... Is it based on the clues provided by Yu Wangwei? ”

"Hmm."

"That's good......"

Xia Chujian's eyes wandered, and he didn't know whether to say something or not.

Huo Yushen stared at her, and the corners of his eyes couldn't help twitching slightly.

Although this girl has great potential, she is still too young, and on the seven feelings, others can know what she is thinking at a glance.

Huo Yushen said with a cold face: "...... If you have something to say, say it. ”

Xia Chujian pursed his lips, and finally asked tentatively: "Is there anything special about the natural gas explosion in our building this time, as well as the autopsies of the dead people?" ”

Huo Yushen immediately asked, "What special place did you find?" ”

“…… You mean, there's nothing special found on the Corrections Department's side? ”

"The Corrections Department's bunch of garbage, you don't have to worry about them finding anything special."

Summer first sees: "......".

Where is she worried, is she disappointed......

Xia Chujian hesitated for a while, and finally said, "Inspector Huo, do you know that I have a young master's black silver mecha......"

Before she finished speaking, Huo Yushen said clearly: "So, this is the reason why you didn't tell others about this special feature?" Including your immediate boss, Meng Guanghui? ”

Xia Chujian nodded calmly: "Inspector Huo is keen." ”

Huo Yushen: "...... Say. ”

Xia Chujian said: "That night, after chatting with Yu Wangwu for half the night, I didn't actually go back to sleep, but put on the black silver mecha of Shao Si Ming and went out for a walk. ”

Huo Yushen: "......".

Xia Chudang didn't see Huo Yushen's increasingly cold expression, and continued: "After I came back, it was already more than three o'clock in the morning, and I found that there was an excess of Teflurane in our corridor at that time. ”

Huo Yushen's expression was slightly awe-inspiring.

In the matter that Xia Chujian said, Huo Yushen did not see it in any investigation materials related to the fire in the residential building E in District 177 of Mulan City North, whether it was Mulan City's own Punishment Division or the branch station under the Special Security Bureau.

That's kind of interesting.

He mused, "How can you be sure it's Teflurane?" How is this determined? ”

Xia Chujian said: "My young master ordered the black silver mecha to test it. ”

After a pause, he said, "I really didn't know that this mech could also measure air quality." ”

Huo Yushen: "......"

His face was cold: "This is not measuring air quality. High-level mecha originally had its own filter identification system to guard against harmful gases. ”

Summer first sees: "......".

Well, it's her who is unheard.

Xia Chujian shrugged his shoulders and said indifferently: "I see, poor, I only use too few order mechas, and I have no concept of other mechas." ”

Huo Yushen stared at her, thinking that she was doing it on purpose.

Where did anyone use this tone to say that Shao Si Ming is a mecha of this level?!

If Meng Guanghui heard Xia Chujian say this, maybe he would beat her up.

But Huo Yushen is also used to the unreliability of Xia Chujian, and he is too lazy to be angry with this kind of person.

His tone was as cold as ever: "Do you know what terflurane does?" ”

Xia Hatsumi heard a little bit of something out of his tone as calm as he could.

She raised an eyebrow and said, "Although my physics grades are at the bottom, my chemistry grades are still passable." ”

"I know that terflurane is a volatile gas that can cause deep coma. My aunt and Wufu had inhaled an overdose of terflurane at the time, so they were unconscious and had to go to the medical cabin for treatment. ”

"But the strange thing is that when my aunt was examined at the Imperial Hospital, the hospital did not detect any terflurane residue, only that they inhaled too much dust......"

Huo Yushen said lightly: "You also know that Teflurane is a volatile gas, and it can stay in the human body for no more than five minutes. ”

"After five minutes, it completely integrates into the bloodstream, rapidly lowering the blood oxygen level of red blood cells, making the human body exhausted, and most people will suffocate to death."

"When terflurane is integrated into red blood cells, there is no residue."

The implication is that if it can be detected, it is really a ghost......

Xia Chu saw "ah" and said: "So vicious?!" This thing is a murderous thing that doesn't blink! Chemistry textbooks don't say it in such detail! If it weren't for the early warning of the young master's mecha, I might have been tricked! ”

Huo Yushen said: "The technical conditions for the synthesis of terflurane are very demanding, the volatility is very strong, and the price is expensive, one milligram costs 1,000 Beichen coins, which is not affordable for ordinary people." ”

Xia Chujian's heart moved, and he asked suspiciously: "So expensive?" So if there is an excess of Teflurane on the entire floor, how many milligrams of Teflurane will it take? ”

Huo Yushen stared at her, and after a while, he said coldly: "You don't know how to count yourself?" Simple math problems. ”

See you at the beginning of summer: "......"

She said unashamedly: "It's too slow to calculate, if Inspector Huo has ready-made data, can you share it?" ”

This answer was not unexpected by Huo Yushen.

He said in a cold voice: "Since your young master order mecha can detect terflurane, there must be data to record and check it yourself." ”

The first time I saw it in the summer, yes!

Since her Shao Si Ming mecha has detected an "excessive" amount of terflurane, it means that there must be data to support it, so it can be said to be "excessive"!

But now she is sitting in the dining room of her new home, and although there is no one around, who knows if someone will suddenly come in?

Her fingers rubbed a few times on the flower necklace around her neck, and she said dejectedly, "Forget it, I'll check it when I go back to the bedroom." ”

Huo Yushen lowered his eyes and said: "In a confined space, it takes two milligrams of terflurane per cubic meter to make an adult weighing one hundred and twenty pounds unconscious. ”

"In an open space, it takes six milligrams of terflurane per cubic meter to put an adult weighing one hundred and twenty pounds unconscious."

Xia Chujian's eyes slowly widened, and he said with a little admiration: "Inspector Huo, how do you know so much?!" ”

This is more than a scholar!

So much data is coming just in the open mouth!

Huo Yushen didn't raise his head, and continued to have an indifferent face: "The Special Security Bureau has a database, and I searched it out." ”

Summer first sees: "......".

White worshipped.

She gathered her mind, quickly calculated by heart, and then said: "We have a floor of about 400 square meters, the floor is three meters high, and the entire floor is 1,200 cubic meters. ”

"Teflurane is released in the floor, it is not completely sealed, but it is not completely open, four milligrams per cubic meter, is it enough to make an adult weighing one hundred and twenty pounds unconscious?"

Huo Yushen nodded: "If you weigh less than one hundred and twenty catties, you will need less terflurane." ”

Xia Chujian immediately said: "That floor needs an average of 4,800 milligrams of terflurane, which is worth 4.8 million Beichen coins. According to my observations, the entire building should be covered with terflurane, we have a total of eleven floors, and we also need at least 52.8 million Beichen coins worth of terflurane. ”

Huo Yushen frowned slightly: "...... Are you sure there are terfluranes throughout the building? ”

"Not sure." Xia Hatsumi said calmly, "But I just suspect that the whole building was terflurane at that time, and all the residents in the building inhaled this volatile gas." Therefore, when the explosion and fire broke out, no one except me was awakened and got up to run for their lives, which caused the tragedy of more than 500 deaths. ”

Huo Yushen said: "So what you mean is that the explosion and fire in the building this time was not accidental, but man-made. ”

Xia Chujian nodded heavily: "...... It's murder! ”

Huo Yushen said: "If it is murder, then what is the motive? Killing so many people is not enough to explain it with psychosis. And psychosis kills people without the need for such means as terflurane. ”
