"This woman told the shopkeeper that she works in a scientific research institute and needs sulfuric acid for experiments, so the amount of each purchase is not much, but the number of times will be relatively frequent. But once the shopkeeper saw her carrying sulfuric acid into the family quarters of the chemical plant, where there was no scientific research unit, so the shopkeeper thought it strange and was impressed by this woman."

"I took a photo of Qin Rongrong and asked the shopkeeper to identify it, and the shopkeeper was very sure that it was this woman who asked him to buy sulfuric acid."

Everyone frowned, and suddenly had a sense of foreboding. A large amount of sulfuric acid can corrode corpses, and its effect is the same as the "corpse pill" in martial arts dramas, although it cannot reach the point where it can melt corpses to the point that nothing remains, but it can also corrode muscle tissue and melt corpses into a pile of black charcoal. Cases of the use of sulfuric acid to dispose of corpses after murder are real.

Another piece of news is relatively simple: "The residents who live downstairs in Qin Rongrong said that the newly moved woman upstairs has been 'clanging' chopping meat in the house in the middle of the night for the past two days, making people unable to sleep."

Everyone's hearts were suddenly clouded. After rushing thousands of times, he was still one step too late, and Qin Rongrong was likely to have already attacked the "prey".

Li Zhudao immediately ordered the arrest. The police have put the entire building under control, and once the other dog jumps over the wall, they must stop the escape at all costs.

After discussion, everyone decided to send Xiao Wu, who has rich experience in actual combat, to disguise himself as a community worker and deceive the door open on the grounds of the census, while Li Zhudao followed behind Xiao Wu and rushed into the scene as soon as he opened the door.

Creeping up to the fourth floor, the distance between everyone and Qin Rongrong was only separated by the rusty red iron door in front of them.

Xiao Wu knocked on the iron door, and the corridor with very poor sound insulation also sounded at the same time.

Through an iron door, Li Zhudao and Xiao Wu vaguely heard the sound of stir-frying vegetables coming from the house.

Seeing that there was no response in the house, Xiao Wu looked back at Li Zhudao with confusion, and after getting his approval, Xiao Wu slapped the iron door with a "bang".

"Who?" There was finally a response in the room.

"Community, do a census." Xiao Wu's tone was tired, like a grassroots worker who has a busy day.

"What kind of census is there at such a late hour? Why don't you come during the day?"

"I went out to work during the day, and I couldn't see anyone."

The footsteps in the room hesitated for a moment, but finally moved slowly.

Li Zhudao and Xiao Wu exchanged glances and quickly swapped places. When the iron door made a "click" sound, Li Zhudao kicked the ground with his right foot, slammed the door open with his left shoulder, and shouted into the house, "Police!"

Xiao Wu followed, but choked on a choking chili smell in the smoke.

The rest of the police officers who were ambushed in the hallway also rushed in, shouting at the house, "Police!"

The sound of the explosion echoed in the room, but it was extremely empty, and everyone saw Li Zhudao standing in front of the toilet door, raising his legs and kicking the door. The toilet is a necessary place for dismembering the corpse, and at this time, the toilet door is closed, and the people inside are busy moving things to block the door.

Without saying a word, everyone joined in kicking the door, lit up the soles of their shoes, and kicked wildly.

In less than half a minute, several large holes were kicked out of the wooden door panel, and the curved door frame could no longer withstand the force, so it broke suddenly, and the wooden door collapsed.

A woman is pressed under the door. Qin Rongrong was arrested.

In the tub of the toilet lay half of the corpse, which had its limbs and head amputated, and had also been disemboweled.

Qin Rongrong was stir-frying in the kitchen just now, and it was the kidneys.

During the interrogation, Li Zhudao hadn't started to ask questions, but Qin Rongrong laughed out loud.

This made both Li Zhudao and Liu Chaogui feel inexplicable.

Li Zhudao made a calm face: "What are you laughing at?"

Qin Rongrong smiled all over his face: "I'm very happy to finally be able to see my family. I didn't dare to go home for two or three years, for fear that you would be secretly watching my house, and as soon as I showed up, I suddenly appeared and arrested me. Now, I don't have to hide from you anymore, and I can meet my family."

"You know what

What did he do?"

"Yes, I killed someone. I know that killing pays for life."

"You know you can still laugh?"

Qin Rongrong laughed even louder: "What is this? I'm not the only one who kills...... Isn't that normal......

"Why eat them?"

"I can't help it...... My liver and kidney function are not good, what to eat...... Anyway, they're all dead, and it's a waste if they don't eat, and I'm not the only one in the world who eats people."

After a pause, Qin Rongrong changed his words again: "People eat everything, eat cereals, grasses, and meat, fly in the sky, run on the ground, swim in the water, as big as whales, elephants, as small as mice, shrimp, why can't they eat people? There aren't many cannibalistic generals in history, which shows that there is nothing abnormal about cannibalism."

Li Zhudao's teeth were about to crush. He wanted to know if Yin Na fell into the hands of Qin Rongrong and Zhao Changkang, and he also wanted to know Yin Na's ending. He wanted to ask directly, but he didn't dare to ask.

Liu Chaogui saw that Li Zhudao's face was getting worse and worse, and looked at Qin Rongrong's gaze as if he was about to erupt into flames, only to think that he was extremely angry at Qin Rongrong's "anti-human" crimes.

Liu Chaogui touched Li Zhudao with his foot under the table, signaling that he couldn't be emotional, and then pulled the question to the case: "Let's talk about the body in the bathtub, who is the deceased? What are you going to do next?"

The smile on Qin Rongrong's face never faded:

"She...... Her name is Liu Yunhui, she is a rich woman, she suspects her husband of cheating, and when she saw the advertisement of a private detective posted by someone I entrusted on the self-media platform, she came to the door."

"I bought a lot of sulfuric acid, and I was about to melt her at dinner tonight, and here you are...... It's not easy to dispose of large pieces of corpses near residential areas of chemical plants, and when they are melted with sulfuric acid, if they are thrown into the garbage dump, even if they are found, they will not be able to see what they are."

Liu Chaogui asked, "Why can't you get through the landline number you left in the advertising slogan?"

It is precisely because of this that the first arrest of Qin Rongrong by the police will fail. They made a phone call for more than ten minutes, but found that the other party had been busy, so they thought that Qin Rongrong was likely to "talk on the phone" with someone in the detective agency.

Qin Rongrong smiled again, explaining that when he was not in the detective agency, he would put the telephone receiver on the table, and he would put the receiver back when he was in the detective agency.

When she was not in the detective agency, no one answered the phone, the sound insulation of the corridor was poor, and the landline ringing that rang for a long time often made noise to a dog raised by the old man opposite. As soon as the dog heard the bell ring, it barked.

Some women who are not in harmony with their husbands and wives sometimes call at any time, especially in the middle of the night and in the dead of night, the ringing of the bell causes the old man's dog to bark loudly, so that the people upstairs and downstairs cannot sleep peacefully. The old man on the other side was even more annoyed and couldn't bear it, so he ran to complain to the neighborhood committee.

The neighborhood committee reported to Qin Rongrong. In order not to cause trouble, Qin Rongrong could only take down the landline earpiece as soon as he left the detective agency.

The truth is as simple as that.

Liu Chaogui continued to ask, "How did you get together with Zhao Changkang? It's the 'Boss Li' of the pig farm."

Qin Rongrong explained with a smile that when she was working in Jin Mingzhi's foot bath city more than two years ago, she wanted to go to a more famous rice noodle shop after getting off work in the early morning, but her colleagues just wanted to go back to sleep, and no one wanted to accompany her, so she took a taxi alone.

When the taxi passed through a dark alley, she was knocked unconscious by the taxi driver's hammer on the door of the head.

This taxi driver is Zhao Changkang.

At that time, Zhao Changkang converted his private car into a taxi, and then parked outside the doors of these colored entertainment venues, as long as he saw a coolly dressed young girl coming out of it, he would drive the car up, and then press the window, revealing his handsome face, and then looked at these lonely girls with inquiring eyes, obviously asking them if they wanted a ride.

Qin Rongrong said that Zhao Changkang looks delicate and has gentle eyes.

There is even some shyness when he looks at the girl, and he looks like a shy big boy in the neighborhood, which not only does not make people think that he is in any danger, but even makes the girls feel cute.

These dusty women are bold, and some of them will take the initiative to talk to them as soon as they get in the car, and even make teasing words. Zhao Changkang often replied with a red face and red ears, but at the same time, he quietly touched the hammer, and then suddenly knocked down the hammer on the top of the girls' heads.

When Qin Rongrong woke up, she found herself tied to a large table, and the taxi driver was putting a rope around her neck.

Qin Rongrong reacted immediately, knowing that this person wanted to kill her, so he immediately opened his mouth to beg for mercy, Zhao Changkang stopped what he was doing, but said, "Don't waste your efforts, everyone who arrives here will be like this, but it's useless."

After finishing speaking, he tightened the rope in his hand.

But within a few seconds, the rope suddenly snapped.

Qin Rongrong escaped death, and he didn't care about the hot pain in his neck, he just took a greedy breath. Zhao Changkang was quite annoyed, and after throwing away the rope, he rummaged in the house for a while, and finally found a piece of wire and put it on Qin Rongrong's neck, but found that the wire was not long enough, and after wrapping around Qin Rongrong's neck, the rest of the part made him unable to pull it up at all.

Zhao Changkang threw away the wire very unhappily, and picked up the most convenient small hammer, in order to ensure that this hammer would not have problems, he deliberately held the wooden handle and waved the hammer in the air a few times, who knew that waving it, the head of the hammer suddenly flew out.

What the hell.

After Zhao Changkang was stunned for a long time, he simply threw away the wooden handle in his hand and stared at Qin Rongrong instead: "It seems that you should not be killed, but you have to give me a reason not to kill you."
