"What is missing is this set of equations." Liang Yi stared straight at the strange equations composed of bloody numbers and letters on the stone wall of the culvert. The key to solving the mystery may very well lie in this set of equations.

There are three mysteries at the crime scene that have yet to be solved.

The first is that the head of the female victim is missing among the broken corpses. In addition, the deceased did not have any valid personal documents, and the true identity of the deceased is confusing. This has brought great obstacles to the breakthrough of the case. The vast majority of murders

The average probability of crimes, including vendettas, murders of love, and crimes committed by acquaintances is more than 90%. Starting from the victim's interpersonal circle is the most effective way to solve the case. Who has the victim had a history with, especially who has he interacted with recently?

Close, can be used as the entry point of the case.

The second is what does this set of equations that seem to have nothing to do with the corpse dumping case mean? Liang Yi tried to solve the equations, but he couldn't solve it at all in two days. Only two of the three unknown quantities corresponded

Are these strange numbers and letters deliberately left by the arrogant murderer to challenge the authority of the police?

The third reason is why the murderer did this. Judging from the way he cut the body, the murderer was very professional and must have good psychological quality. The hair on the private parts of the victim's female body was shaved clean, and the victim's hands and feet were specially cut.

The nails are neatly trimmed, colorful manicures are done, and the inside of the nails are also specially treated.

"Liang Tou, this set of equations has no results at all. It is completely impossible to find the values ​​​​of x, y, and z. They are also written with the victim's blood?" Feng Wei was a little nervous by this strange aura. If it was

She was really a little frightened when she was asked to come alone.

Liang Yi almost pressed his face to the stone wall of the culvert and looked at it carefully, "No, the forensic doctor has identified that the blood on the wall is not the blood type of the deceased. It is not yet known what kind of blood it is. The forensic doctor has preliminarily concluded that it is human

It’s unlikely that it’s blood, it’s probably animal blood.”

The strong flashlight in Liang Yi's hand flickered and shone on his chin. His face in the dim light looked quite ferocious.

Feng Wei could only stand aside and watch the somewhat gloomy scene quietly.

"Hey, I found it." Liang Yi said with a stern face, "Feng Wei, come here to help. There is an empty space behind this group of small stone walls with equations written on them. There should be something."

Liang Yi grinned. He is usually indifferent and has a straight face. He rarely talks except for topics related to the case. However, as long as there are new developments and new evidence in the case, Liang Yi changes back to the sunny person he was before.

A confident and wise big boy.

Feng Wei hurriedly wiped the sweat mixed with rain on her face, held a strong flashlight, and focused the light on the stone wall with the equations written on it.

Liang Yi wore gloves and kept testing, looking for the imaginary point where the small stone plates connected.

Click.

A crisp sound.

Liang Yi gently removed a small square stone slab about forty centimeters in size.

There was a human head covered in heavy makeup.

This is a girl with beautiful features, with double ponytails, eyes wide with fear, her nose has been flattened, and the dense threads on her mouth are sewn very neatly. If you look at it suddenly, it looks like there is a centipede lying on her lips.

superior.

Feng Wei's palms were sweating. Although she had seen many corpses and heads soaked in formalin solution, a head dressed up like a witch, placed alone and alone, was too soul-stirring.

"There is something inside." Feng Wei pointed to the underside of the girl's head.

Liang Yi leaned over and took a look. Under the neck of the woman's head, there was a piece of yellow paper with strange lines painted on it with cinnabar. It looked intuitively like a Taoist talisman of feudal superstition.

"Zhou Haiyang, bring your brothers and come over immediately. There are major discoveries at the scene where the body was dumped."

Liang Yi held his cell phone and turned around half a circle. This case of body dismemberment and dumping was definitely not as simple as it seemed on the surface. "Also, forensic doctor Han Qi must come."

"Liangtou, I was about to call you. The case analysis meeting is about to start. Where have you been? What's there? If you don't find anything special, come back quickly. Director He is furious and wants to slap us!" Zhou Haiyang

At the scene of the case analysis meeting, he gently left his seat and lowered his voice.

"A human head was found behind the stone wall at the scene where the body was dumped. No ink marks!" Liang Yi hung up the phone.

Haigang City Police Department, Case Analysis Conference Room.

Director He, who is in charge of public security, anti-terrorism and criminal investigation, has an upright look on his shoulders, a blazing gaze, and a frown on his face. "We are the people's police, and you are criminal police officers. You must be worthy of the clothes you wear. It has been three days, and the identity of the deceased has not been confirmed. We

How do I explain it to the hall?"

"Reporters from news media, Weibo, newspapers and self-media are all going crazy."

"How can we reassure the citizens of Haigang City? Haigang City, as one of the cities to be selected as a model for national public security, has just passed the preliminary review, and this happened? Isn't this a slap in the face?"

Except for the loud bell-like voice congratulating the director, the scene of the case analysis was eerily quiet.

Zhou Haiyang suddenly opened the door and rushed into the conference room excitedly, "Congratulations, Captain Liang found a female head behind the stone wall of the culvert at the scene where the body was dumped."

Director He's eyes flashed and he made a decision immediately, "The forensics department, technical team, and forensic team immediately went to the crime scene, and the search area was expanded to a radius of seven kilometers centered on the crime site!"

Police lights flash.

Six police cars, sirens blaring, moved forward in the rainy night.

Zhou Haiyang got into the work truck of the forensic team. When he looked up, he saw forensic doctor Han Qi with a pair of charming big eyes and a surgical mask. Zhou Haiyang grinned slightly and took the initiative to approach Han Qi.

"Doctor Han."

"We don't talk about personal matters during working hours." Han Qi's slender white hands carefully sorted out the organ knives, tweezers, bone hammer, craniotomy saw, hemostatic forceps, scalpel in the survey tool box...

"I'll say it again, I'm a forensic doctor, not a doctor." Han Qi said coldly to Zhou Haiyang.

Zhou Haiyang rubbed his hands. He and Han Qi were junior high school classmates. The beautiful Han Qi was almost the center of attention wherever she went. After graduating from medical school, Han Qi had a very stable job in a tertiary hospital. I don’t know what it was.

Because of this, Han Qi voluntarily gave up her job in a tertiary hospital, passed the examination and became a forensic doctor at the Haigang City Police Station.

"It's about the two of us, your parents and my parents, you?" Zhou Haiyang had a smile on his face. Han Qi personally went out and could handle it alone. No one from the other forensic teams arrived in time.

In the MPV work vehicle, apart from the driver, there were only two people, Zhou Haiyang and Han Qi.

Zhou Haiyang is tall and tall, with thick eyebrows and big eyes, and dark skin. He is less than 1.7 meters tall. Han Qi is nearly 1.8 meters tall and has a good face. After get off work, she puts on a fashionable windbreaker and is almost the same as a Victoria's Secret model. Enough to confuse the fake with the real thing.

"Forcing girls into prostitution?"

Han Qi closed the lid of the investigation box tightly, "Zhou Haiyang, I think you should focus all your attention on your work. If you catch the criminal in this case with your own hands, I might consider it."

"Really?" Zhou Haiyang opened his mouth and his whole teeth were exposed.

"This is a serial murder case. Someone will definitely die. The sooner this perverted guy is caught, the less one victim will die." Before the police station held a case analysis meeting, Han Qi had been working continuously for more than 25 years.

During this period, she did not sleep a wink except eating and going to the toilet. Through various blood sources, blood types, smells, etc., Han Qi had determined that the blood that wrote the equations on the culvert stone wall at the scene of the corpse dumping was from

Dog blood.

"Serial murder case?" Zhou Haiyang completely disagreed with Han Qi's words, "In cases of body dismemberment and dumping, based on comprehensive data analysis from many countries around the world, the cool-down period for killers generally exceeds a week. The hall wants us to

It will take a week to solve the case, and it will definitely be solved. Now that the whole city has deployed it, it will give criminals a great deterrent. It will not be that easy if we still want to follow the same method and throw the bodies into pieces."

"In some feudal superstitions, dog blood has the effect of warding off evil spirits and eliminating disasters. Captain Liang found a woman's head at the crime scene, with a yellow talisman written in cinnabar pressed under the head."

Han Qi paused, "The blood, the yellow talisman, the flattened nose bones, the unbreakable equation, do you still think this is just an ordinary criminal case?"

Zhou Haiyang rubbed his head, "A crime involving high IQ seeking social recognition? It is indeed a bit evil. Could it be that this is a sacrificial ritual? Are there still people who believe in such nonsense?"

Heavy rain made the originally wet and slippery road surface even more muddy.

With red and blue police lights flashing, they slowly drove towards the scene where the body was dumped.

Seeing so many people coming to the police station, Feng Wei's nervousness calmed down a little.

Feng Wei watched helplessly as the off-road vehicle parked near the noodle shop hit the police car. With the faint flash of lights, she could see that the person driving the off-road vehicle was the tall and thin man, but after he got out of the car, he was nowhere to be seen.

Under the large locust tree in the bush, a man in red wearing a white mask appeared and suddenly disappeared.

There was also Mr. Liao from the radio station, who uttered wild words about killing people, and said with a sinister smile that there would be corpses in Huahua Port tomorrow.

Feng Wei felt dizzy, her stomach was churning, and the corpse odor emitted from the female head mixed with the humid air, and she thought of a maggot crawling out of the flat nasal cavity of the head, squirming and bending.

Woo.

Feng Wei covered her mouth, quickly ran to the side, bent over and started to vomit wildly.

Liang Yi followed closely and patted Feng Wei's back gently, "I've already seen that you feel nauseous and want to vomit. Go ahead and vomit. It's always like this in the beginning, and you'll get used to it."

"In our line of work, few girls can persevere. Some time ago, there was a girl who fainted several times and was forced to transfer to a grassroots police station and became a registered police officer."

"I'm sorry, Liang Tou, I've embarrassed our Third Criminal Investigation Team." Feng Wei wiped her mouth and took a long breath, "Stand up from where you fell. I will personally remove the head of the deceased woman from

Take it out from the stone wall."

"Can you do it? That is a very important piece of evidence. It cannot be broken or contaminated. It is very likely that some key evidence such as fingerprints will be left on it." Liang Yi looked at Feng Wei with a slightly worried look. Such a level of practice would be unacceptable to a person.

The criminal police officer who had just arrived was still a girl, and she was under too much pressure both mentally and physically.

"I can do it!" Feng Wei's eyes were persistent.

"That's it." Liang Yi vaguely saw the perseverance of his dead wife from Feng Wei's body, "You come and take out this head, I will be your deputy, forensic doctor Han Qi will be here soon, she

Very rich experience.”

"If corpses and other attachments appear at the crime scene, a forensic doctor must come to the scene in person. Han Qi will guide you. Logically speaking, Han Qi needs to do this kind of thing herself. I will also ask Han Qi to let you do it with your own hands.

Take out the head."

"Thank you, Liang Tou." Feng Wei patted her chest, feeling a pain and itching in her esophagus due to the burning stomach acid.

Six police cars stopped in order.

Han Qi was the first to jump out of the car, carrying a white survey box. Zhou Haiyang quickly followed Han Qi, holding an umbrella attentively.

"Captain Liang." Seeing Liang Yi, a smile appeared on Han Qi's cold face, "You are the only one left in our police station, and you are indeed the best."
