Yan Yu never understood why Lao Qian would act alone since he had deliberately set a trap and waited for the murderer to come to the door.

When I arrived at the scene, I finally knew the reason.

Although the uncles like to pretend to be gods and ghosts, they have not yet risen to immortals, and they are still ordinary people, and they still have to eat, drink, and sleep in the end.

The small bamboo house in front of them is where they solve their physiological problems, on the left is the shower room, where a few wooden barrels are placed, and on the right is the toilet, there is no dirt, there is no smell, but it looks very clean, and there is even the residual smell of incense.

There is a bucket of grass and wood ash in the toilet, which shows that although these old men have low requirements for material life, they are very particular about cleanliness.

The toilet floor is gravel, which is very comfortable to step on and looks clean, and the pool of blood has been integrated into the gravel and soaked to saturation.

Yan Yu walked in and took a look, and was also surprised.

Because there was no trace of a fight at the scene!

Lao Qian is an old man from Dunhuang Mountain, with extraordinary skills, why didn't he resist a little?

Even if there is no big fight, after being bled out, the legs and feet will twitch and the like, there will inevitably be traces, after all, it is a gravel floor, and the small stones are very loose.

Yan Yu squatted down and saw that there was no sign that the ground had been swept flat, and all signs showed that Lao Qian did not resist, or even struggle!

"Why didn't you resist?" Generally speaking, unless it is an acquaintance who commits the crime, but this is just that there is no resistance, in the process of being killed, there will be some struggles, even if it is withdrawing, kicking the legs, etc., it will leave traces, how can it be so clean?

"Did you use medicine?"

If the murderer first stuns Lao Qian and then kills him, he will not resist, but whether there is any medication or not needs to be confirmed by an autopsy.

Write a strict psychological profile of the murderer, such a conceited person should disdain to use medicine, but in order to ensure that nothing goes wrong, medication is the safest way.

After all, Dean Qi was also unable to move, and his chest was opened by the murderer, so thinking about it, the murderer should have no psychological burden on the medication.

However, the use of drugs is not so fast, unless it is a strong chemical such as chloroform or **, but at this time, there is no residual odor.

Just like the murderer's usual style, there was no trace left in the toilet, Yan Yu walked back to the room, looked at Lao Qian's neck, and touched his cervical vertebrae one by one.

"Uncle Shi, you are more familiar, you touch it."

Zhao Tongyi walked over and touched it, then nodded at Yan Yu and said, "Your guess should be correct, it was the hand knife that knocked out first, and then the hand ......."

Yan Yu has always thought that it was a drug, but there is another situation, that is, he was knocked unconscious.

Of course, the most common method is to slam the back of the head, but then it is easy to kill the target directly.

And there is another situation that is more common in literature and film and television works, where a slash on the neck can knock people unconscious.

But it takes a lot of force, and it takes a lot of power.

Under the slam blow, the carotid artery is compressed, and the short-term blood supply to the brain is insufficient, which will cause fainting, but if the force is not well controlled, it will also be fatal.

The murderer just couldn't control his strength, so that the cervical spine was misaligned.

Although no valuable clues were found in the toilet, this cervical dislocation was not meaningless.

Maybe in the search for the murderer, there is no criminal investigation value, but in terms of psychological profiling, it is of great significance!

For a long time, Yan Yu's advantage lies in the psychological profile of the murderer, and the murderer's almost pathological conceit is a key to Yan Yu's clenching.

After entering Dunhuang Mountain, what kind of psychological state the murderer is also directly affects the coping strategies of Yan Yu and others.

Just like the dislocation of the cervical vertebrae, it is said that it will not happen to the murderer.

The murderer was so meticulous that he opened Dean Qi's chest, but he still saved his life, and he had a strong knowledge of surgery and human anatomy, so it was said that he could easily stun Lao Qian and not hit the cervical spine out of place.

This happens, which can only show that the murderer can't stand the pressure of Dunhuang Mountain, he is no longer as calm as before, and it can even be said that he is a little panicked in the chaos.

This kind of conceit will bring him great self-confidence, make him calm and composed, and commit crimes in an orderly manner, but once he is frustrated and his conceit is broken, then his flaws will become more and more, and he will even collapse because of this!

And if you want to make him even more flustered and force him into a state of collapse, you must continue to stimulate him!

Thinking of this, Yan Yu said to Zhao Tongyi: "Uncle Shi, I want to open the eight doors." ”

"Open the eight doors? You're going to let him go? Not only Zhao Tongxiao, but others were also a little anxious.

"This man killed Lao Qian, how can we let him go!"

All along, the murderer had the opportunity to kill Yan Yu, but he didn't do it, but made a bet with Yan Yu to kill seven people within seven days, and finally killed Yan Yu.

It's all about his conceit, which is the most crucial part of shaping his godhead, as if to show that there is nothing he can't do, because he is the god who controls the weather and human life.

But when he killed Lao Qian, he was afraid of the strength of Dunhuang Mountain, so he still knocked Lao Qian unconscious before attacking, which revealed the flaws and made Yan Yu see his panic.

The closure of the eight gates of Dunhuang Mountain can certainly put pressure on him and block him inside, just like catching a turtle in an urn.

Zhao Tongyi and others know Dunhuang Mountain well, they only need to wait until dawn, they don't need to dig three feet into the ground, they should be able to find out this person.

Yan Yu offered to open eight points, which is tantamount to letting the murderer go!

But in Yan Yu's opinion, this is not the case, opening the eight doors is not to let go of the murderer, but to provoke him, to stimulate him!

In today's Dunhuang Mountain, the murderer has fallen into passivity, Yan Yu has a clear advantage here, if the eight gates are released, the murderer will have doubts.

First, he will be worried that there is a killing move hidden behind the action of opening the eight gates, and he will waver, and second, even if he knows that there is no fraud, once he goes out of the eight gates, it is equivalent to accepting Yan Yu's alms, and rejecting Yan Yu's provocation, which is equivalent to admitting defeat to Yan Yu!

Returning home and walking away in disgrace has never been something that a conceited murderer wants to do!

Therefore, in Yan Yu's mind, even if the eight doors are opened, the murderer will not leave from now on, but will feel humiliated by Yan Yu because of this, so he will be angry and take the initiative to commit the second crime!

In this way, Dunhuang Mountain does not need to dig three feet into the ground to find him, just wait for the rabbit and wait for him to come to the door!

The advantage of the murderer is that he hides in the shadows, never goes head-to-head, emerges from the heavy rain and darkness, kills someone, and disappears into the heavy rain and darkness.

If you open the eight doors and be able to force the murderer to have a head-to-head confrontation, it will be very worthwhile!

Of course, all of this is Yan Yu's speculation and profile of the murderer's psychology after all, once he makes a mistake, or the murderer is shameless and skinless, then it is equivalent to letting the murderer go once.

Everyone the murderer kills next, Yan Yu will be responsible for his conscience!

Zhao Tongyi was also thinking, he was silent for a long time, and asked cautiously towards Yan Yu, "How sure are you?" ”

Yan Yu didn't answer, but asked: "If you face each other head-on, how sure are the uncles who can catch the murderer?" ”

Although Dunhuang Mountain is all old guys, they are all powerful characters, these people are alone in the empty mountain, their hearts are strong-willed, the old brothers can be said to have been like brothers, and the killing of old money has already aroused their anger.

If the murderer really dares to confront him head-on, they will never let the murderer go away even if they risk their lives.

"As long as he dares to come, he shouldn't be able to leave." Although Zhao Tongyi did not say everything, he could clearly feel the confidence of Dunhuang Mountain.

Yan Yu nodded: "If you open the eight gates, I don't think he will leave ninety percent......"

Although I am sure that the murderer will not leave, there are exceptions to everything, and Yan Yu is not a murderer in the end, and I don't know where the murderer is hiding, let alone what the murderer's situation is now, where I dare to say 100%.

Ninety percent is actually very high, but not to mention the chance of one percent left, even if there is a chance of 0.01 left, it is extremely irresponsible to let go of the murderer and let him kill people everywhere.

Zhao Tongxuan and Zhao Tongxuan muttered and discussed for a while, but they didn't seem to be able to make up their minds for a while.

Meng Jiefang and Hong Dafu are still in a coma, although they are equipped with guns, but Yan Yu does not dare to use them without authorization, completely relying on the people of Dunhuang Mountain, there is no deterrent weapon, and if you want to subdue the murderer, you can only rely on fists and feet.

Zhao Tongyi and others were also hesitating, and several people turned from whispering to loud arguments.

Although Yan Yu didn't deliberately eavesdrop, he could still hear some vaguely, and it seemed that Zhao Tongyi was the only one who supported him.

Others think that they have now gained the upper hand, and there is no need to risk the people outside.

Zhao Tongyi is not an authoritarian person, after finishing the discussion, he walked over and shook his head at Yan Yu: "Everyone still thinks it's safer to close the door and beat the dog......

Yan Yu also smiled bitterly: "It's understandable, this is a normal consideration, but in this way, the murderer will be even more excited, he likes such games......"

Zhao Tongyi was also helpless: "The brothers are willing to give it a try, so let them try it first." ”

Yan Yu wanted to fight for it, but he could see everyone's expressions, so he swallowed the words back into his stomach: "Then let's try it first......"

"It's just that in this way, you can only blindly go to the end, if you don't open the eight doors now, then you can only stick to the end, even if there is only the last person left, you must not open it again, otherwise the murderer will become more and more inflated, and there will be no way to curb his murderous intent......"

Zhao Tongyi also frowned, turned his head to look at the old brothers, and sighed softly after all.

"Everyone has been here for so many years, and they have long been like brothers, and the old money is dead like this, they have to fight after all, let them go......"

seemed to feel that what he said was too pessimistic, and Zhao Tongyi also changed the topic: "You take a rest first, they will go out to check the situation of Bamen, you should also rest and recuperate, since you have decided to close the door and fight the dog, how to catch him this time!" ”
