"Soak into the chemical tank farm?"

"Put it all into corrosive acid?"

Everyone, including Zhao Donglai, took a deep breath, while Zhou Fan slumped down on the chair.

They couldn't imagine that horrific scene.

Heartbreaking pain, skin peeling off, flesh being melted, what on earth should it feel like?

At this time, everyone had goosebumps.

Luo Fei also felt a chill in his heart. Judging from the previous deployment of additional security personnel in the chemical tank area, Ning Zitao just didn't want to be discovered there. If that was the case, that would be the scene of the first crime!

"Beast!"

Zhou Fan stood up suddenly, his eyes blazing.

He played the most critical role in this incident, because he was the one who led the investigation a few months ago, and now he and Luo Fei went to investigate the scene to collect clues for the second time.

During this period, he had contact with Ning Zitao and was infected by the other party's sincere feelings.

He thought it was very difficult for the man who lost his brother, and he did not take the initiative to doubt the other person. He even tried to help the other person get away with it when Luo Fei made a series of conjectures.

I didn’t expect that by connecting the above causes and effects, it was actually this guy who did it!

Even he must admit that Ning Zitao is the most suspicious now!

The security personnel were arranged after he became the person in charge, so that was the first reason!

Colleagues, subordinates, and even his brother were involved, but in the end he was the only one to escape, and he became the first person to talk things over under the factory director.

Isn’t this the biggest beneficiary?

If all kinds of crimes are carried out, I can't wait to kill him with one shot.

Anyone who can do such a trick is definitely a complete pervert. He only regrets that he has no law enforcement ability! But as a police officer, you must remain calm at this moment.

"But, Luo Fei, if it were really soaked in the entire tank area, corroded by tons of raw reagent solution, and brutally killed, would there really be no calcified bones left?"

Zhou Fan asked in a low voice.

"Of course there will be some left."

Luo Fei answered seriously, and then looked at him.

"And right under our noses..."

"You mean..."

"Do you still remember the technical employee we met on the way to the workshop with Ning Zitao? He reported something at that time, the pipeline was blocked!"

Zhou Fan was enlightened and his eyes instantly became horrified.

"Could it be that all the broken objects and the remaining calcified bones in the tank farm are... all..."

At this moment, Zhou Fan was speechless.

He didn't expect things to be so horrific.

"It seems that this is the only explanation."

Luo Fei looked at the other people.

"At that time, the staff member of the technical department came to report to Ning Zitao and explain what happened below. His reaction at that time made me pay some attention."

"The other party does not recommend replacing the pipes and repairing them. They need to use dredging agent for a period of time. They say they will be repaired at the end of the year."

"At first I thought he was just being stingy or trying to save costs. After all, for large chemical plants, it is a big project to deal with such pipeline repairs that affect the entire industry chain. But now that I think about it, it becomes more and more strange."

"It happens that there have been frequent blockages in recent times. There must be something wrong here!"

Several other people also nodded.

Zhao Donglai looked at the display board in front of him with burning eyes.

"So the bodies of the nine people who were killed have now been completely eroded, and the last traces are stuck in the lower pipes with the broken calcium fluoride?"

Luo Fei nodded.

I finally connected all these together. I thought there was something fishy here before, but now it seems that the clues cannot be hidden.

Liao Xingyu stood up and looked at Zhao Donglai beside him.

"Captain Zhao, give the order and declare the collection order directly. Let's go take a look together."

"Yes, if the evidence is down there, we will definitely gain something."

After hearing what everyone said, Zhao Donglai coughed coldly.

"The job of a criminal police officer is to detect, not to search and investigate arbitrarily. How is that different from a cruel official? Although we can analyze and deduce evidence, we cannot act rashly without persuasive conditions."

"good……"

Luo Fei, who was meditating on the side, also spoke. At this time, he was already thinking about a new question.

If Ning Zitao really did this, how did he hide it from others?

It would take time for him to kill nine living people in the tank area, but if they were thrown directly into the tank area, the noise would be too great, and there would definitely be a reaction inside the tank area, and the outside world would also be aware of it.

But that was the scene of the first crime after all. What methods did the other party use?

Unconsciously, it was already evening during the discussion.

A group of people went downstairs for a midnight snack. Zhao Donglai and the others were still discussing and analyzing, so they chose to eat in batches.

Luo Fei and his team found a noodle shop and prepared to make a simple meal.

Just when everyone was getting ready to eat, the phone suddenly rang.

Luo Fei saw that it was Yang Mei who was calling, but the call from the other party was still a video call.

This is more personal!

Luo Fei got up and went outside to connect. As soon as the call was connected, his eyes widened and he took a deep breath.

Although the person opposite was his girlfriend, I had never seen such scenery before. She was wearing a pair of pink shorts and a cool camisole on her upper body. With the surrounding sea breeze blowing, her figure looked very attractive in the night.

"What? I'm stunned!"

Yang Mei's light laughter sounded.

Luo Fei quickly adjusted.

"It's so beautiful. It's really hard to control yourself like this."

"Tch, that won't work. You are still a people's policeman who has won awards for meritorious service. Don't you have any determination at all?"

After receiving Luo Fei's praise, Yang Mei's cheeks turned a little crimson.

"I'm already very conservative, look at that bitch."

Then following the direction of the camera and Yang Mei's finger, Luo Fei saw Wu Xiaoyue who was frantically posing for a photo.

That's the real three o'clock beauty, bikini temptation!

However, although the other party's figure is good, there is still a gap compared with Yang Mei. Luo Fei's thoughts are naturally on his girlfriend.

"By the way, why don't you dress like this? Are you afraid of the cold?"

"Stop coming!"

"Binhai is much warmer than Jiangzhou. Although there is sea breeze at night, the temperature here is just right for me."

Yang Mei looked shy.

"It's not because of you, and you're not with me anymore. I don't want to dress like that to attract attention. Don't you care?"

"Of course I care!"

Luo Fei, who was planning to make a joke just now, suddenly became serious. This is his own woman, how could he let others see her at will?

"How are you doing lately? I heard from my uncle that you are running around investigating cases again."

"Yes, work for the people and make money for yourself!"

Luo Fei moved his shoulders.

"Come and see the sea with me. You can't come with me this time. You have to make up for it later."

"no problem."

Yang Mei was walking on the beach with her mobile phone. Her slim figure and close-fitting vest looked particularly graceful and delicate in the wind. Looking at the night scene on his mobile phone, Luo Fei felt a little more relaxed.

Suddenly he noticed several people taking pictures side by side in the distance. They lay together and leaned against the shore, letting the waves hit them.

With the constant ebb and flow of the sea water, the bodies of the people laughing and chatting were constantly covered with sand and sand, which was quickly washed away. The feeling of soaking in the water looked very comfortable.

Suddenly Luo Fei's eyes changed.

That's right! It turns out that this is the principle!

During the meal, Luo Fei was in a good mood and ate two large bowls in one go. The others were a little confused and looked more happy than having solved the case.

"Team leader, what's wrong with you?"

"Yeah, it's like this after just answering a phone call? Could it be that Ning Zitao confessed?"

"Eat yours."

Luo Fei pointed at a few people.

"Come back with me after eating! I know what's going on."

Although they didn't know what Luo Fei was talking about, as team members, they knew that there must be a new breakthrough.

In the evening, Luo Fei and the others took the food back directly, while Zhao Donglai and others were also left behind. The purpose was to strike while the iron was hot and discuss the matter clearly.

"Everyone, I thought of it!"

Luo Fei looked at the few people with a very surprised tone.

"Captain Zhao, do you still remember the details of the scene I told you before? Those hemp rope marks I found, I know the function of these ropes!"

"What is it?"

Everyone turned their attention to Luo Fei.

"He did not throw people directly into the tank area. As the director of the material area, he is quite familiar with the chemical raw materials. Although the inside of the tank is sealed, there is also a monitoring system. If there is a large foreign body, Entering it will trigger an alarm."

"So he hung the nine people with thick hemp ropes and put them in from the filling inlet. They were just halfway up. In addition, these raw materials were constantly added and taken out, and the strong acid inside formed a rolling and churning cycle. system."

At this point, Luo Fei stopped.

Zhao Donglai, Liao Xingyu and the others also stopped using their chopsticks.

There was collective silence.

At this moment, the same picture appeared in their minds. Nine people were hung in a confined space, surrounded by chemical raw materials. They allowed strong acid to wash away their bodies. All their skin, flesh and blood were devoured and peeled off, and they were constantly tortured by burning and bone-piercing pain. them.

"terrible……"

Zhao Hai and the others took a deep breath. At this moment, their hearts were filled with a layer of fear.

There will be such a tragic scene in the dark confined space.

It is terrible!

Zhao Donglai kept nodding.

"I understand, now I understand everything. The marks you saw, Luo Fei, were not left when the hemp ropes were tied, but were caused by the constant pulling and friction of those people during the fierce struggle."

After hearing this explanation, Luo Fei nodded.

All this is thanks to the video call Yang Mei gave to herself.

Under the continuous washing of the sea water, the sediment comes and goes by, so that you can feel the waves without having to go into the water.

In the same way, Ning Zitao must have used this method to silence all nine people.

Only in this way can we explain what happened to the hemp rope marks. The scratches on the hardened metal showed how painful it was for people who were soaked in hydrofluoric acid.

"If that's the case, it would explain why he didn't attract anyone else's attention."

Zhou Fan said thoughtfully.

"He only needs to hang the person inside, and then he can leave. No matter what he does outside, it will not affect the death of the person inside."

"Those remaining bone residues and calcified limb fragments will flow out along with the diluted discharged filtrate until they get stuck in the lower pipes. This is really unnoticed."

Zhao Dong came to look at Luo Fei.

"Maybe we can close the net."

"Not urgent!"

Luo Fei still had a doubt in his heart, and then looked at Lin Xin and the others.

"Please catch up on the progress of the Longke Chemical survey project that I told you. You will work overtime tonight and send me the survey results and some detailed information from the project manager tomorrow."

"I'm going to meet someone tomorrow!"

"Who?"

"Ning Zidong's family!"

The next day, Luo Fei rang the doorbell in a landscaped community located in a busy section of the city.

The only people who came with him this time were He Xin and Lin Jie.

On the other side, Zhao Donglai and the others had already put the Longke Chemical factory under surveillance with the cooperation of the Public Security Bureau.

"Who?"

It was a woman, probably Ning Zidong's wife. Her voice sounded a little haggard.

"Hello, Ms. Du, we are from the Criminal Investigation Brigade. We are here mainly for the case of your husband's previous disappearance. We have some clues recently and came to find out about it from you."

After a while, the door opened, and a woman with a pretty face but a vicissitudes of life who had obviously suffered a lot of damage received them.

"Comrade police, please come in."

When Luo Fei entered the house, he saw two children lying on the table doing homework. They were Ning Zidong's children.

The two children were very well-behaved. When they saw the police coming, they immediately got up and returned to the bedroom.

"Comrade police, please sit down."

From his previous understanding, Luo Fei learned that this lady's name was Du Yuhan and that she had been married to Ning Zidong for eight years.

Ning Zidong's incident shocked the other party quite a bit, and it was obvious that the relationship between the couple was really good.

"Ms. Du, we are here this time to learn more about Mr. Ning from you."

"Officer Zhou already visited last time, but there's no result yet?"

"It's like this. There are new developments in the case. I hope you can cooperate with us to learn more about it."

"it is good."

Du Yuhan nodded, with a bit of disappointment and sadness in his eyes.

"I want to know what kind of person your husband is? I hope you can tell us about his personality and temper as well as his work status."

Du Yuhan sighed softly.

"My husband has a bad temper. Sometimes he gets angry impulsively over small things, and he can't control himself. At first, I was worried that he would be violent or affect the family, but later I discovered that he is very good to me and good to the children. He has always been gentle.”

"I understand, is there anything else?"

Luo Fei took notes carefully.

"There is also work. We have been together for eight years, and his work status has never been dull."

"We had a child four years ago. After that, my husband often traveled out to socialize. It was not until the last year or two that his work suddenly improved significantly, and our living conditions have also been greatly improved."

At this moment, Luo Fei's eyes moved.

Sudden change? It seems there is indeed a mystery here!
