On this day, Luo Zong came to Jiulitun to report that the fertilizer plant had restarted, and there were many fresh faces in Xiaojiang Village, and I heard that it was brought by Director Zheng, who took over the construction of the fertilizer plant.

As soon as he heard the surname Zheng, he almost didn't have to deliberately inquire, Xu Weiguo could confirm that the person who took over the fertilizer factory must be Zheng Qiuhua.

Sure enough, Luo Zong's investigation results also confirmed this.

When Xu Weiguo told Lin Xiaoman about this, Lin Xiaoman knew that the peaceful days were coming to an end again.

Chu Xiao's confession explained the matter of the virus and biological research laboratory very clearly, but the process of leaking research data similar to the drone of the Third Aircraft Department, and how the data was transported out of the country were explained a little vaguely.

vaguely, there are many incidents that Xu Weiguo has already investigated, but has not yet been reported, including the shocking conjecture of the two of them about the fertilizer factory last time, Chu Xiao did not even mention a word.

There are two explanations for this situation, one is that Chu Xiao did not finish speaking, and the other is that Chu Xiao did not know, or did not handle it. If Chu Xiao didn't say it, it's okay, if it's the second case, it means that there are still many loopholes in the matter of Bigen Building, and these loopholes can't be closed before a reasonable explanation for a day, even if in the eyes of everyone, Bigen Louzi has died out steadily, Xu Weiguo will secretly continue to investigate, and will not stop until the moment the truth is revealed.

These days, it seems to be peaceful, but in fact, Xu Weiguo has been investigating these ambiguous things.

Everyone thought that the Bigen Building had been destroyed, but Xu Weiguo didn't think so.

In fact, the reason why Chu Xiao pleaded guilty was because of Zheng Qiuhua's conversation with her.

If Zheng Qiuhua had not participated in it, judging from the evidence available at that time, Chu Xiao would not have been convicted.

Although the three points put forward by Zheng Qiuhua are indeed failures, it is not easy to prove them.

Sphincter repair surgery, this kind of surgery is not unusual, prolapse, congenital dysplasia, or acquired tears and some diseases can cause sphincter relaxation, if Chu Xiao doesn't say it herself, she is because she has transported white face in the body too many times to cause sphincter relaxation, serious to the point of fecal incontinence, anyone will think about the reason for her surgery prolapse or disease.

Unless Chu Xiao's body is caught on the spot and the white face is transported, and everyone is stolen, is it possible that everyone who has done the repair surgery is because of the white face?

As for the matter of taking blood for antibodies, it cannot be confirmed, it is just a psychological tactic in reconnaissance methods. After the antibodies enter the body, it actually takes a while to detect them, so it is not so quick to prove that Chu Xiao has three times the number of antibodies in his body.

In other words, if Chu Xiao resisted the interrogation at that time, in fact, in a short period of time, there is really no conclusive evidence to prove that she is a spy.

Wu Heng's interrogation Chu Xiao resisted, but after chatting with Zheng Qiuhua for a few words, he took the initiative to confess the crime, which was problematic in itself.

It's just that Wu Heng was anxious to receive the credit, for fear that the credit would be lost, so he hurriedly typed the report.

Wu Heng's psychological tactics did not have any effect on Chu Xiao, but Zheng Qiuhua's received miraculous results, which proved that Zheng Qiuhua's psychology was stronger than Wu Heng's, and people with strong reconnaissance ability also had strong anti-reconnaissance ability.

In the screening and interrogation of butterflies, Zheng Qiuhua successfully cleared the suspicion, and in the screening and interrogation of flowers, Zheng Qiuhua successfully cleared his name again.

Zheng Qiuhua is not simple.

Over the past few days, Xu Weiguo has been releasing a message out, no matter who asks about Bigen Louzi, he has an answer, hasn't it been clear?

Even if Wu Heng deliberately called to show off after accepting the commendation, Xu Weiguo was still quiet.

It was because of this wrong information that Zheng Qiuhua hibernated for a while, and only after confirming that Xu Weiguo did not suspect the matter of the fertilizer factory did he dare to come back and take over.

Xu Weiguo trusted his own judgment, so he kept waiting, waiting to see the new owner of the fertilizer factory in Xiaojiang Village.

As expected, the person who came was indeed Zheng Qiuhua.

So, the investigations he did in the shadows came in handy.

It took almost two months to build the fertilizer plant, and after the fertilizer plant was built, a lot of machinery and equipment were dragged first, and then a lot of lumpy coke and anthracite were moved.

As soon as the raw materials are in place, the machines in the fertilizer factory roar day and night, and they work overtime to start producing fertilizer. The raw material is prepared into a raw gas mainly containing hydrogen and nitrogen gas, and then the impurities other than hydrogen and nitrogen in the raw gas are removed to purify the raw gas, and after purification, the purified relatively pure nitrogen, hydrogen ratio of 1:3 nitrogen and hydrogen mixed gas will be compressed to a high-pressure state, synthesized into ammonia under the action of catalyst and high temperature, and then the ammonia will be further processed to obtain nitrogen fertilizer.

After the people arranged by Xu Weiguo entered the fertilizer factory, they worked honestly, and then every day after work, they would record everything that happened that day and send it back to Jiulitun.

In addition to nitrogen fertilizer, the mainstream products of fertilizer factories also include ammonium nitrate, urea and other fertilizers.

Just looking at the process flow, there is no abnormality at all.

As for the formula in the technical room, it can't be touched at all, and that piece is very tightly guarded. It is precisely because the guards are too strict, except for those brought by Zheng Qiuhua herself, others are not allowed to be approached at all, and the confidentiality measures are more perfect than the confidentiality measures of the high-precision research laboratory, and a small fertilizer factory technical room actually has the scale of dozens of guards.

Although these dozens of people are all technicians on the surface, they are all windy under their feet, strong and strong, and they are all bulging in the same position on their waists, so they should all be pinned to them.

So, in this seemingly normal fertilizer factory, the technical room is the weirdest place.

After the first batch of chemical fertilizers was produced, Xu Weiguo went in to take samples and send them to the Fine Chemistry Laboratory for testing.

The result is normal, just ordinary proportions of normal fertilizers.

Three batches of fertilizer in a row are normal.

It wasn't until the fourth batch that minor differences were detected.

The first three batches of normal fertilizers have been put into use, and the fertilizers after the fourth batch have been accurately recorded after leaving the factory, where they are sold and how much they are sold.

In the three months since the plant was built, 135 tonnes of fertiliser have been produced, of which only 35 tonnes are normal.

After grasping the exact evidence, it took another two months for Xu Weiguo to send undercover personnel to the fertilizer factory to find out the bottom of the fertilizer factory, and in the days that followed, Xu Weiguo had been planning the arrest operation.

This operation is very dangerous, fertilizer in the production process, gas purification and compression process, a slight carelessness will produce a large area of explosion, so the safety management measures of the fertilizer plant has always been the priority, and Zheng Qiuhua also used this as a legitimate excuse, in addition to the secret security measures, but also set up a patrol security team of 50 people, specifically for safety management inspections.

These 50 people, plus those hidden forces disguised as technicians, there are hundreds of armed forces in the fertilizer factory, hundreds of people, even in ordinary situations, if they want to carry out arrests, it is very likely that there will be mistakes and omissions, and there are a few fish that slip through the net.

If you want to complete the arrest in the fertilizer plant, it is more difficult, more cumbersome to operate, and basically an impossible task to complete.

When arresting, unless they are caught in one net, if there are any fish that slip through the net, they will go directly to the gas-making workshop and set a fire, and the entire fertilizer plant will be blown up into the sky.

There are still two or three hundred ordinary workers in the fertilizer factory, and there are two villages nearby.

The slightest negligence is enough to cause tragedy.
