It may be that the good luck ran out, and not long after leaving the armed police hospital, I encountered a traffic jam.

The traffic jam is the most annoying, even if they are not in a hurry, looking at the long queue of slow vehicles, everyone also feels that their hearts are in a panic, and there is a fire of ignorance burning slowly.

Especially when it comes to the stopper, it is even more infuriating, and some road rage patients may just kick the accelerator up.

Fortunately, Su Ping's car was equipped with a cylindrical police light on the roof, although the siren was not sounded at the moment, it was also flashing red and blue lights alternately, and Qi Yuan, the co-pilot, was wearing a police uniform, and no driver around dared to plug them without a long eye.

So although Su Ping was a little bored, he could still bear it.

Of course, although Su Ping has a bad temper, his own quality is still quite high, so he walks honestly in his own lane.

Finally passed the congestion section, Su Ping stepped on the accelerator, and the speed of the car immediately increased.

After some more travel, they came to the place where S&H got off the bus.

Su Ping pulled over and flashed, and then asked, "Here, do you have an impression?" ”

Shi Enshen's eyes rose slightly, as if she was remembering something, and after a while, she nodded: "I remember, I took a taxi when I left, and I got off here." ”

After a pause, she raised her two hands at the same time - because the wrists were handcuffed and the hands could not be separated - stretched out her right index finger and pointed forward and said: "Specifically, it is the street sign on the side of the bus stop in front, there happened to be a bus behind at that time, so the driver urged more tightly, and I was deeply impressed and could remember." ”

Su Ping bowed his head slightly, this is right, there is no problem.

So he glanced at Qi Yuan, motioned for him and the two policewomen to take Shi Enshen out of the car and continue to move forward, and he parked the car on the nearby state-owned parking lane.

Qi Yuan understood, first took out the mask and sunglasses and handed them to Shi Enshen for her to put on, and then unbuckled his seat belt and got out of the car.

After all, Shi Enshen is only a suspect, and she has not been convicted of the crime, and judging from the current clues, she is likely to be quite innocent, and it remains to be said whether the crime of harboring is established.

Under the conditions, Qi Yuan is quite willing to take the initiative to protect her personal privacy.

Then the door on the right side of the rear seat also opened, Ning Yuke leaned out of the car under her feet, and then bent down to help Shi Enshen's hand to help her out, and finally another policewoman came down and stood next to Shi Enshen, and Ning Yuke sandwiched her between left and right.

At this time, there were a lot of pedestrians on the road, and when they saw this battle, they all looked sideways at them.

Qi Yuan ignored these gazes, turned back to Shi Enshen and said, "Let's go forward now, if you sound something, just say it directly, and when you get to the place where you and Han Kunsheng meet, you can open your mouth if you think about it, it doesn't matter if you don't think about it, let's go through it first, and then turn back." ”

Shi Enshen nodded.

The group then walked down the sidewalk.

Shi Enshen squinted, looking left and right from time to time, his face was a little confused - but these were covered by masks and sunglasses, and the three detectives couldn't see it at all.

Obviously, she only remembered the place where she got off the bus, and she still had no impression of the short 100-meter road.

But suddenly, she turned her head, looked up and down a few times, and said, "There." ”

"Oh?" Qi Yuan turned around and asked, "You mean we've gone through, right?" ”

Shi Enshen nodded.

So the people turned around and walked back to a tree, next to the garbage can, and Shi Enshen said, "This is it." I remembered that Han Kunsheng was smoking here at that time, flicking cigarette ash into the ash tray on the top of the trash can from time to time, and holding a briefcase under the arm of his left hand. ”

Qi Yuan nodded lightly again, and this location was also matched.

About five meters back from the trash can, there is a thick iron rod with a huge round ultra-clear night vision camera hanging on it.

This security monitoring has no intention of concealing it at all, and even the iron rod has directly posted a sign on it, which reads the monitoring unit.

In recent years, a lot of surveillance has been put in such a big way, and there are many fewer hidden probes.

"Anything else you can remember?" Qi Yuan asked, and at the same time, his eyes squinted slightly, looking in the direction when he got off the car-Su Ping was standing there smoking by the trash can, looking at them silently, seeing Qi Yuan's gaze, he raised his hand to signal, and then continued to stand there.

He didn't want to rush forward and affect Shi Enshen and interrupt her state.

So Qi Yuan also withdrew his gaze and continued to look at her.

It's a pity that she is wearing a mask and sunglasses, and she can't see anything.

Finally she shook her head and spoke:

"I don't remember very well, but I remember that I talked to him for a while, and he said something to me, and I seemed to be quite stimulated...... After that, I still took the bag and left, and then I still don't have much of an impression. ”

Qi Yuan pursed his lips.

On the way to the hospital, Su Ping showed him the monitoring of Shi Enshen and Amu's meeting, and after they talked for a while, Shi Enshen seemed to be a little stimulated and slightly emotional. But look, she is still trying her best to suppress it, and judging from the shape of her mouth, her voice is still very low.

Looking at the reactions of the passers-by on the side, they should not have noticed what they were saying.

So Shi Enshen's memories can be matched at this time.

But the most crucial piece of information is what exactly they talked about. It's a pity that Shi Enshen can't remember these details either.

After a moment, Qi Yuan nodded lightly and said yes, and then encouraged, "Can you think of any more information?" ”

Shi Enshen was silent for a while, then raised his head, raised his chin and said, "I can only ring that I was going this way at that time." ”

"Then let's move on." Qi Yuan said—Shi Enshen's chin was pointing in the direction she was leaving.

After a while, several people walked up to Su Ping's side.

Su Ping didn't say a word, and silently hung his head at the end.

Soon came to an intersection, Shi Enshen hesitated for a while, pointed to the left, and said, "After that, I seem to be going here." ”

"Then we'll go over and have a look." Qi Yuan said.

And this time, S&H didn't point the wrong way.

Next, several people turned around in this small area, and from time to time they would turn back dozens of meters to choose a new direction.

Overall, they are quite reliable, even if there are occasional deviations, but they will be corrected back soon, and the trajectory map drawn by colleagues in the Graphic Investigation Department can be matched at present.

But......

At an extremely complex interchange with multiple roads converging and a complex pedestrian bridge design, with a little bit of a "mountain city" connotation, S&H was stunned.

After pacing back and forth on the overpass several times, her brain completely shut down, and she couldn't remember how to go.

It's also a kilometre away from the bar where they are partying, an area that S&H is not familiar with.

She didn't have a good sense of direction, and she couldn't tell the difference between southeast and northwest at this point, otherwise she would still be able to get a hand out of the general direction of the bar - of course, the right way didn't make any real sense.

Qi Yuan raised his head and sighed lightly, then looked at Su Ping and asked, "Team Su, what should I do now?" ”

"Follow her trajectory at the time to get off the flyover, leave this complicated traffic, and then continue to lead the way to find it back." Su Ping said.

He replied hello, and then said hard work to Ning Yuke and the others, and led the way out of this intersection in front.

Judging from the trajectory map alone, although Shi Enshen agreed to Amu's request and decided to help her at that time, she should still be very entangled in her heart, so she kept walking around and aimlessly, and finally made up her mind before she walked to the bar and drove her car away.

Well, the possibility of getting lost is also possible, but it is relatively low. Judging from the surveillance, at that time, her drug effect had not really attacked, and her sanity was still there, and if she found that she was lost, she should open the navigation and take a look.

"Huh?" Thinking of this, Qi Yuan was slightly stunned, then hurriedly looked at Su Ping, and walked to his side without a trace.

But he didn't expect Su Ping to flash two steps to the side.

Qi Yuan looked at him with a confused expression, and then saw him say with disgust: "Walking well, suddenly came over to dry the hammer?" I especially want to pretend to be casual. ”

"......" The corners of Qi Yuan's mouth twitched, and he said, "That, I thought of something." ”

"Oh, then you say." Su Ping pursed his lips and took the initiative to approach Qi Yuan.

After a while, Qi Yuan said: "I just want to ask, if you eat something like diacetylmorphine—and after eating a large amount, how long will it take to hallucinate and cause people to lose consciousness?" ”

"This question ......" Su Ping glanced at him: "You actually thought of it?" ”

"Uh......" Qi Yuan said, "I thought of it before, but I forgot it when I turned around." ”

"Excuses." Su Ping rolled his eyes, and then said: "Regarding this issue, Lao Xun and I specifically consulted and discussed with Lao Xun, and then he pulled a set of complex drug agent kinetics for us. ”

Qi Yuan pinched his chin and asked, "Then what?" ”

"In general, it varies from person to person, and it also depends on the dosage and ingestion method, but also depends on the purity of the drug." Su Ping didn't sell it, and said directly: "Theoretically, the blood concentration of this thing can cause a poisoning reaction when it reaches three milligrams per liter, and the lethal dose for oral administration is about two hundred and forty milligrams per kilogram."

In addition, diacetylmorphine is metabolized very quickly in the body, metabolizing into a variety of different enlightenments, and there will be different stages of symptoms, which is very complicated.

For example, after it is ingested into the human body through the digestive system, it is quickly broken down into 6-monoacetylmorphine by its own hydrolysis and cholinesterase hydrolysis, and then further deacetylated and metabolized into morphine, which is then further converted into morphine-3-β-glucoxilate and some morphine-6-β-glucuronide ......"

"That ......" Qi Yuan sniffed hard, and asked Su Ping with a weak heart, "Can we not go into such detail?" I don't understand and I can't remember. ”

"Actually, I had to work hard at the time." Su Ping said with a sigh: "So you have to memorize it too, and I'll take a test for you when I go back." ”

Qi Yuan: ???

"No, I don't bring such a Su team." Qi Yuan wailed: "Can't you ask me to work hard with you because of the hard work you carry......

"Today's teachers, most of them were students, and they had endless homework." Su Ping said with emotion: "And now they have entered the job and become teachers...... Hehe, it's a cycle. ”

Qi Yuan held his forehead: "Okay, I'll carry it." And then what? ”

"The first few are metabolized very quickly in the body," Su Ping said.

"The half-life of diacetylmorphine converted to 6-monoacetylmorphine after absorption is about five minutes, and the time for all the transformation to be completed is between ten and fifteen minutes, and then the half-life of deacetylation is five to twenty-five minutes, which is generally completed within forty minutes."

After a pause, he continued: "When diacetylmorphine is absorbed, it will begin to affect the central nervous system, circulatory system, respiratory system and other systems, but the most harmful of them is free morphine. ”

Qi Yuan thought thoughtfully: "So from the time she took it to the time it took effect, causing her to lose consciousness, it was about forty minutes?" ”

"That's not how it counts." Su Ping shook his head: "You missed the absorption time and absorption efficiency of the gastrointestinal tract, and also ignored the symptoms under various blood concentrations - there is a slang in toxicology, which is now quite widespread in all aspects, and talking about toxicity aside from the dose is a hooligan, have you heard of it?" ”

Qi Yuan's face was a little confused, but he quickly bowed his head again and again: "I've heard this." ”

"To put it simply, she can be very high and maybe even hallucinogenic minutes or even seconds after taking the drug." Su Ping said: "But it is still possible to retain a considerable sense of autonomy, acting like drinking a lot, but not yet drunk to the point of being unconscious."

Based on the amount of drug she ingested, combined with the blood concentration of the drug when she was sent to the hospital, and the pharmacokinetics as the basis for calculation, Lao Yan finally came to the conclusion:

Approximately sixty-five and eighty minutes after ingesting the drug, the concentration of the drug in her body exceeded the danger threshold, and the nerve center began to be rapidly and severely suppressed. At the same time, this should be the time when you pull over her car and ask for a DUI check. ”

Qi Yuan took out his notebook and looked at it twice, then nodded lightly, thoughtful.

Su Ping continued: "The time is basically right - she drank the wine in one gulp, and after about five to ten minutes, the party ended, and she took a taxi to leave. Three minutes later, I received a call from Amu, got out of the car two minutes later, met Amu, and separated from Amu seven minutes later.

After that, she went around and around on the road, and after forty-four minutes, she returned to the bar, got into her car and left, and after another eight minutes, you stopped her for drunk driving.

So...... The interval between when she drank a cocktail mixed with a lot of drugs and when she was stopped by you for a drunk driving check was seventy-four minutes, which was exactly within the time frame given by Lao Yan. ”

Qi Yuan nodded lightly: "If the time is right......"

After muttering a few words, he raised his forehead and sighed again, and said, "Then the problem is back to the original point, and the key is what Amu said to Shi Enshen." ”

After speaking, he saw that Su Ping didn't reply, so he asked again: "Then Su Team, do you think it is very likely that Shi Enshen recalled these details?" ”

Su Ping didn't say anything, only said: "Do your best, listen to the destiny of heaven." ”
