After carefully explaining to the Zuo brothers and sisters, Ning Zhiheng returned to the Military Intelligence Investigation Department.

Three days passed quickly, everything was going well, Zhao Jiang, who was in charge of monitoring Du Qian, came back to report that the agents of the Party Affairs Investigation Department had indeed evacuated, and no one was following Du Qian anymore. Ning Zhiheng asked him to continue to monitor and not slack off.

Du Qian has already loudly claimed outside that his new backer is Ning Zhiheng, the head of the Military Intelligence Investigation Department, but so far, there has been no change on the side of the police headquarters.

However, the investigation of the Zuo brothers and sisters has already reached a rough result.

In the living room of the Zuo family, Ning Zhiheng looked at the few materials in his hand and asked, "Have you figured out all these situations?" ”

Zuo Gang said respectfully: "I have checked the general situation, but I haven't checked it in detail, for fear of missing the line!" ”

Ning Zhiheng nodded and said: "That's it, let's go for a trip tonight, first check the warehouse of Hengfeng Trading Company, if there is no warehousing record, check their account books!" ”

Ning Zhiheng's idea is to start with the transportation process of the goods, as long as it is possible to handle the links of the goods operation records, check them to see if there are any clues.

That night, Ning Zhiheng and Zuo Gang both asked Zuo Rou to give some disguises, and Ning Zhiheng and Zuo Gang's appearance suddenly became much older, with wrinkles piling up on their foreheads, and they were wearing blue workers' clothes, completely like two middle-aged workers!

The two of them rushed all the way to the courtyard of the warehouse of Hengfeng Trading Company, the courtyard wall was very high, but for the two of them, it was not a problem.

Zuo Gang and Ning Zhiheng both turned over separately, Zuo Gang knew that Ning Zhiheng's skills must be good, but he witnessed Ning Zhiheng's agility like a tanuki, and his gestures were silent, and he couldn't help but secretly admire, if he wasn't by Ning Zhiheng's side, it would be almost difficult to detect his movements.

As an old man who is used to doing this, he can't compare to an officer when he does this kind of trick of going over the wall and crossing the house, which is really embarrassing and discouraged to think about.

When he came to the vicinity of a two-story tile house in the courtyard, Zuo Gang pointed and said in a low voice: "There is a guard on duty downstairs, and the upstairs is the office, and the records of warehousing should be upstairs." ”

Ning Zhiheng nodded, Zuo Gang motioned for him to wait, and he stepped forward slowly, he had stepped on it a little bit in the past two days, and after groping for a while, he sneaked into the house.

After a while, he opened the door and waved his hand to Ning Zhiheng in the dark, and Ning Zhiheng quickly walked up to the room.

"People are already unconscious, and now they can't wake up even if it's thunder!" Zuo Gang pointed to the room, these were what he was used to, and it didn't take much effort at all.

Ning Zhiheng also nodded secretly, in terms of skill, Sun Jiacheng was able to suppress the Zuo brothers and sisters under his own hands, but these Jianghu methods were only a little inferior.

The two of them went upstairs, Ning Zhiheng signaled Zuo Gang not to move, he first forcibly memorized the environment and layout inside the room, and then he started to search.

Zuo Gang watched Ning Zhiheng's search move lightly, and carefully restored to its original state after every search, only to know why he was not allowed to intervene, it seems that the real agent is much more meticulous and careful than himself.

Soon Ning Zhiheng found a record book, and when he opened it, it was a record of goods entering and leaving the warehouse.

He carefully observed some records of nearly twenty days of entry and exit, especially those from a week ago, but unfortunately, there was no record of that batch of cotton cloth at all.

I checked it carefully again to confirm that there were no omissions, and it seems that this batch of goods was shipped directly and did not change hands here.

Ning Zhiheng was not surprised, he just checked step by step, if he could find out the record of that batch from here, it would be the best, if not, then continue to check up, such a large batch of goods was transferred by hand, it is impossible that there is no trace at all.

After cleaning up all the traces, the two of them exited the warehouse compound the same way, and waited until tomorrow when the staff on duty woke up, even if they found that something was wrong, they could not find the problem.

Then the two came to Hengfeng Trading Company not far away, and Zuo Gang pointed to the office building in front of him and said: "The east side of the second floor is the office of Hengfeng Trading Company, and the third room on the right turn at the staircase is the accounting room!" There are no on-duty staff here at night, but their door lock is very strong, it is a new lock with a double hole, and it takes some time to open! ”

Ning Zhiheng nodded, it seems that Zuo Gang is very careful, he has carefully touched all the situations in the past two days, this is the first time they have done things for Ning Zhiheng, of course, they are in the spirit of twelve points, and the preparation work is very sufficient.

The two of them climbed directly to the second floor, entered the building through the ventilation window at the staircase, and soon came to the door of the accounting office of Hengfeng Trading Company.

Zuo Gang took out a cloth bag, and after unfolding it, it was full of all kinds of small lock-picking tools.

"Then I'll leave it to you, don't rush to take your time, don't damage the lock cylinder and leak the wind!" Ning Zhiheng said.

Zuo Gang nodded and began to unlock it, time passed little by little, and finally with a "snap", the lock ring opened gently.

The two of them pushed the door in, turned around and gently closed the door, just like last time, Zuo Gang did not move at the door now, and Ning Zhiheng was responsible for the search.

The layout in this accounting room was very simple, Ning Zhiheng remembered it for a while, and began to search, and found a small safe in the corner of the room. There should be more important things in it, and there should be a small amount of cash or important documents.

I hope it won't be hidden in the safe, if that's the case, Ning Zhiheng can only give up, he and Zuo Gang don't have the ability to open the safe without a trace, then the next step can only start with the personnel of Hengfeng Trading Company, such as the accountant who handles the tax entry procedures, the specific clerk who takes the car and goods through the customs, and so on.

However, as long as people are involved, and people are not dead things, there are too many uncertainties in it, and it is possible to leak the rumors, which is contrary to Ning Zhiheng's original intention.

He wanted to find the person in charge of the drug front of the underground party organization without alarming anyone, otherwise wouldn't it be faster for him to find Wan Huarong directly?

He carefully searched for the document records of the past twenty days, fortunately Ning Zhiheng's luck was good, this kind of ordinary shipping documents were not so important, Ning Zhiheng finally found what he wanted.

This is a purchase slip from eight days ago, which indicates that Hengfeng Trading Company purchased a batch of cotton cloth from Demao Company.

The time and goods are right, it should be the batch of goods that Du Qian said, Ning Zhiheng wrote down the contents of the documents, got what he needed, he quickly restored the original state, cleaned up the traces, and Zuo Gang exited the accounting office, locked the door, and returned the same way.

At this time, it was already the middle of the night, and the two of them returned to Zuo's house all the way, Ning Zhiheng explained to Zuo Gang: "Find out this Demao company, find out the background and situation of this company, especially the person in charge of the company, as well as the situation of their company's transport vehicles, and then report to me as soon as possible." ”

Zuo Gang nodded and accepted the order, saying that he would definitely find out the situation as soon as possible and return to his life. Ning Zhiheng went home to rest.

Zuo Gang's movements were very fast, and the next night, he reported the investigation one by one.

"This Demao company is near Hengfeng Trading Company, is a new company that has just been established, the façade is not large, the scale is average, the company's manager is the boss, called Zhu Hongbo, in his early forties." Zuo Gang carefully reported to Ning Zhiheng.

"Just founded? How many days have passed! Ning Zhiheng asked.

"About half a month!" Zuo Gang replied.

As soon as Ning Zhiheng heard this, he knew that his goal should be right, Wu Quanjiang had an accident for more than 20 days, and the transportation line of the underground party organization had to be latent for a period of time, and then set out to establish a new drug transportation line and opened this Demao company, and the time arrangement was very clear!

"Are there any transport vehicles?" Ning Zhiheng asked.

"Their backyard is a big compound, and when I passed by the door, I saw an old truck parked there, and their company is not very large, so it shouldn't be able to afford more vehicles!" Zuo Gang said.

In this era, it is still more expensive to maintain a truck, first of all, the car itself is expensive, then the gasoline is expensive, and then the repair cost is expensive.

"Monitor this Zhu Hongbo, record the places he has been to in a day, and the people he has seen, remember, you only need records of places and people, and other things such as specific conversations are not needed, just record them from a distance! This person is very likely to have anti-tracking capabilities, you have no experience in surveillance, don't get too close, it's easy to startle him. Ning Zhiheng commanded, he didn't know whether the Zuo brothers and sisters had the ability to track the target, so he didn't dare to take risks.

"Got it, far away record, never close!" Zuo Gang nodded, to be honest, they have also done this kind of thing, and they have some experience, but since Ning Zhiheng specially ordered it, they didn't dare to disobey it! Ning Zhiheng's meaning is very simple, everything is based on the principle of not alarming the target.

"Also, pay more attention to the situation of the transport vehicles in their backyard, and notify me if there is any change!" Ning Zhiheng commanded again.

The next two days were calm until Du Qian called to report.

"Team leader, now that the two trucks of Hengfeng Trading Company have returned and are being inspected at the Kangyuankou checkpoint, what instructions do you have?" Du Qian asked respectfully, Ning Zhiheng specially explained, and found that these trucks had to be reported immediately, how could he dare to have the slightest slack against his new master, he had been staring at the Kangyuankou checkpoint for the past five days, for fear of missing the target.

finally made a discovery today, and he hurriedly reported it to Ning Zhiheng as soon as possible.

"What's on the car?" Ning Zhiheng asked.

"The documents are all very ordinary mainland specialties, we have checked carefully, there is no problem! Do you want me to take them down? Du Qian asked carefully.

"What is deducted for normal cargo transportation? Release! Ning Zhiheng instructed, he didn't want to say more on the phone, so he hung up with a simple order!
