Xu Ying looked at Lao Fang suspiciously, and asked, "A lot of preparation and homework"?

After comparing the wounds, it was found that the sharp weapon used by the murderer should be a medical scalpel, which is commonly known as a lancet, with a very narrow edge but extremely sharp. It was not easy to control, but the depth of each wound on the corpse was almost the same, all of them were pointed, deliberately avoiding large blood vessels, and a large amount of cotton wool was found in the wound."

"Cotton wool, what does this mean"?

"This shows that while the murderer tortured the victim, he actually took certain measures to stop the bleeding, the bleeding area was filled with cotton wool, and the indentation of the tourniquet was found near the wound, the murderer was definitely prepared, he thought about it from the beginning, let the victim suffer to the extreme but not die immediately."

"You mean to say that it is better to let him live than to die"? Xu Ying was shocked, but it also confirmed Xu Donglai's speculation at the beginning.

"I think that the murderer's hatred for the deceased must be deep in his bones, but he is by no means a reckless person, on the contrary, he can be described with care." The old man slapped his middle finger on the table, revealing a rare sad expression, "We didn't find any hair, footprints and fingerprints related to the murderer at the scene, and the evidence that could be left was cleared, and there were many droplets of blood falling vertically next to the corpse."

"Blood drips"?

"In the process of the murderer's knife, even if he is careful, he will cut off some small blood vessels, and it is inevitable that blood will be splashed, in order to avoid staining himself, he should be covered with a layer of disposable rain gear suitable for carrying all over his body to cover it, so that the blood will splash on the surface of the dry and slippery raincoat, and will not absorb it, but will drip to the ground due to gravity."

"It's unexpected"! Xu Ying couldn't help but sigh: "The murderer is so well prepared."

……

Coming back from the appraisal office, Xu Ying went to the technical investigation non-stop, but at this time, Xu Donglai was not there, and she asked the technical investigators who were still watching the surveillance: "Where is our captain"?

"It seems that he has gone to the scene, and there are some problems that he needs to research, and he can't sleep if he can't figure it out"! Someone answered.

Can't figure it out? Xu Ying was puzzled, pointed to the monitoring screen, and wanted to ask if the murderer had been found.

After thinking about it, she felt that it was better to ask Xu Dong directly, she went back to the office to get a police flashlight, and drove to Hengshui Villa.

She was wearing a police uniform, and the security guard guarding the door opened the door without saying much, but the strange thing was that when she came to the side of the terrorist train tunnel, there was no figure of Xu Donglai, she called twice, and there was no response.

At this time, it was close to midnight, and the scene was silent, except for the sound of insects attracted by the light, Xu Ying only heard the sound of feet stepping on the ground.

She walked back and forth a few times and didn't see Xu Donglai, and couldn't help but be a little impatient, just at this moment, the light of the flashlight suddenly shone on a strange portrait.

Xu Ying instinctively jumped, took a few steps back, and finally realized that it was not a monster in front of her, but a bronze statue of Amos that she had seen before.

At this moment, under the illumination of the light, the golden sword in Amos's hand was emitting a bewitching light, as if it was about to smash everything nearby.

"Hey"!

In the night, there seemed to be a voice, and then I felt someone knock on the shoulder.

Xu Ying didn't turn her head, and directly came with an elbow inch and a back kick.

"Eldest sister, you took the wrong medicine!" After taking the next two moves, Nan Nan complained unceremoniously.

She heard the shouting and deliberately answered from a distance, if it wasn't for her good skills, she was afraid that she would be hit twice by this eldest sister, and some of them would suffer.

Xu Ying heard it clearly and turned around, but instead of apologizing, she was helpless, did this little girl know that people are scared to death.

Sighed and asked, "What about our captain"?

"That stupid uncle is investigating around the horror train to see if there is a secret room or a secret passage, I told him that the murderer of this murder must be a top master, using the catkins to enter the track, but he didn't believe it." The girl drooped, obviously unhappy.

Just as he was talking about Cao Cao, Xu Donglai appeared, he walked up to Xu Ying, patted the dust on his trouser leg, and said, "Xiaoying is here, did you bring the report?"

Xu Ying handed over the document bag in her hand. He also took a flashlight to light him.

Xu Donglai took out the autopsy report and read it several times, frowning deeply, his eyes full of terrible bloodshots.

"An hour, as I guessed, the murderer would have taken at least an hour to commit the crime." He kept repeating it.

Xu Ying asked anxiously: "Head, has the murderer been found in the surveillance?"

Xu Donglai's hand holding the information froze, sighed deeply, and said: "I and the technical investigators numbered all the tourists approaching the tunnel one by one, and recorded the time point when everyone appeared and left in the picture, as well as the interval between staying in the monitoring blind corner, within two hours when Xuan Yi entered the monitoring blind corner, there were 135 tourists who approached the horror train, but all of these people were only for a short break, even if many people entered the monitoring blind spot during the period, no one stayed in it for more than five minutes. Not to mention an hour so long."

Xu Ying was completely unexpected, and said: "This is not scientific."

Xu Donglai shook his head and said in frustration: "I also know it's incredible, but it happened, and, according to the monitoring interception in the morning and evening a few days ago, there are no more and no less construction personnel, which to a large extent shows that hiding in the track too early is not very valid, but it is not ruled out that the murderer entered from the middle, and there should always be traces of leaving, right?"

Of course, in order to make sure of the doubts in their hearts, the technical investigators are conducting the most detailed inspection of the surveillance from a few days ago, and they also want to see if the surveillance video will be tampered with.

There is no effective conclusion from the monitoring for the time being, and at present, we can only consider the motive of the crime.

The wind blew in the middle of the night, making Xu Donglai shiver.

"Uncle, please respect us, okay?" Nan Nan pouted unhappily and said.

Xu Donglai smiled bitterly: "Little Ancestor......" He really wanted to say that he was annoying now, could he not make trouble, and turned into a sigh for a long time: "You say"!

"Beautiful sister, you shine the flashlight well, and I'll show you what it means to come and go without a trace, and tread the snow without a trace." Nan Nan pointed to the direction, which was the part of the monitored distance.

Her words fell, only in an instant, Xu Donglai and Xu Ying looked horrified, although they knew that she was very strong, but they never expected that she would be so strong.

The two of them obviously saw that the little girl was still there in the last second, but in the next second, she was not like a wind, leaving an afterimage and leaving, but the kind of disappearance out of thin air, without even the slightest sign.

What kind of skill is this? When Xu Dong came to this time, he knew that what he said was not false, and the matter of the fifth section was no trivial matter, so this murder case, the story behind him, could he solve it by himself?

Suddenly he had a question?

At this time, a voice came from a distance, which clearly entered their ears in the dead of night: "Uncle, if you are a master, you can enter the orbit quietly."

When she jumped over, Xu Donglai frowned, and asked solemnly: "Comrade Yan Ruoshi, I want to know if your department has exact news, or this is just your personal opinion, which is directly related to my next investigation direction, I hope you will tell me truthfully."

He had seen Nannan's certificate, and the name on it was Yan Ruoshi.

At this time, he was eager to know if there were uncontrollable factors that had entered their realm, just like the little girl's strange skills, Xu Donglai knew that even if the murderer stood in front of him, they might not be able to arrest him easily.

If the two little girls have no intention of meeting and want to do their part, then the case has to be talked about twice.

Nan Nan's eyes were erratic, and she didn't dare to meet Xu Donglai's eyes, and after a while, she smiled and said: "Uncle, do you know that I am two Sailor Moon full of a sense of justice, and I can always do my part when I encounter such a thing"?

"In that case, it's not a special order from your department, and there is no so-called criminal gang that endangers the country?" Xu Donglai couldn't help but breathe a sigh of relief, if there were really uncontrollable factors, at the foot of this Tianzi, the pressure on him, the squad leader of the Criminal Investigation Department, was really not ordinary.

He stared intently at the two girls who had mysteriously appeared beside him, hoping that fate would not play a false joke on him.

Nan Nan struggled for a while in her heart, and finally reason defeated greed, although she played the world, she had her own bottom line, Lao Xing had been transmitting thoughts, joking with the enemy, and forcibly wiped out; Joke with friends, just click on it, don't be willful and lose Jingzhou.

Personality, she has been flamboyant, now is the time to show honesty.

While Xu Donglai listened to her slowly exclaimed, he couldn't help but ease his strength, and rekindled his previously low heart, as long as it was not a crime beyond the scope of his cognition, he was full of confidence.

Although it cannot be ruled out at present, there are super masters involved, otherwise this god has entered the trajectory unconsciously, how can it be explained?

Although this is a line of thought, but with Xu Donglai's many years of criminal investigation experience, he feels that there may be another situation in this, he believes that a master, it should be said that a super master who can evade a thousand times the sluggish surveillance, they are born with a kind of arrogance, it is not strange to kill, a capital predator may be high in the eyes of others, but in their eyes it is an ant.

Treat ants who will be bored to cut a thousand knives, unless it is a grassroots, horizontal line of people.

He turned his eyes to Xu Ying next to him, this elite who specializes in psychology, whether she has a unique opinion.

At this time, Xu Ying had the same doubts about this unknown mystery.

At that moment, eyes met, and they seemed to read each other's thoughts.
