The surveillance methods of Wu Entai were in place one after another. After about a week of investigation, the police and uncles unexpectedly discovered that this kid was extremely honest.

My biggest hobby is to stay at home and watch martial arts dramas like "Storm and Clouds" on a computer. Occasionally, Xu Jian came to pick him up, and he also had afternoon tea or strolled in the surrounding scenic spots.

The most bizarre thing is that Wu Entai actually likes to go to Cantonese opera teahouses to listen to short plays. If he goes out, almost half of them will hang out among a group of old men and ladies, tinker with some tea, and listen to music with desserts and shaking his head.

"What else can I find?" Gao Sheng asked after reading the reports of several field teams.

"No more, his residence, mobile phones and broadband used are all under our monitoring." The head of the field team replied.

"Old Jia, where are you?" Gao Sheng turned around and asked Jia Chengliang, the captain of the anti-drug brigade.

"No." Jia Chengliang shook his head and said, "We have been staring at Wu Entai's contact person. Apart from Xu Jian, there is only one Malay Chinese, Lin Haizhen.

Xu Jian has always played the role of a driver. We judge that he is a newcomer after all, and he should not know any core news in a short period of time. The correct monitoring of Lin Haizhen shows that this person is busy with his travel company business most of the time.

I contacted Wu Entai several times, and my posture was very low. I didn’t mention anything except caring about Wu’s life needs."

"Hey, I'm seeing the ghost. Is this grandson named Wu who came here to take a vacation?" Gao Sheng said angrily.

"Da Shenger, why don't you take further measures?" Jia Chengliang made a suggestion.

"Let's go and find a bureau seat." Gao Sheng greeted Jia Chengliang and the two went out to go straight to the city bureau.

The "further means" Jia Chengliang mentioned does not mean taking Wu Entai back to the bureau and locking up for trial, but rather using more in-depth technical investigation methods.

For example, placing surveillance and monitoring equipment in the residences of the target person and in the vehicles they often ride, collecting investigations and intelligence into every detail of the lives of the three target persons.

In other words, even eating and going to the toilet are included in the monitoring range, so you have to take a good look at whether Wu Entai is here for vacation.

If so, although this kid has never committed a case in China, he has been on the wanted list of several Southeast Asian countries. He was arrested and handed over to the Interpol to finish the matter.

If not, then keep watching. If he wants to get Azrael to sell domestically, he must have entry channels and distribution next door. After all, he has figured out the problem and directly packaged it and caught it together.

Everyone did not believe that Wu Entai entered the country with a pseudonym, but it was as simple as coming for vacation, and the leaders of the municipal bureau also believed it. Therefore, Gao Sheng and Jia Chengliang's application were quickly approved.

To further monitor Wu Entai’s daily details, various hidden monitoring equipment is indispensable. Although these things can be obtained in the technical department of the Municipal Bureau, Gao Sheng no longer looks down on those "backward" Wanying.

After obtaining approval from the municipal bureau, he led Jia Chengliang straight to the courtyard of the Military Region Logistics Department.

"Comrade Gao, are you here again?" Qu Sen asked when he was dragged to the doorstep to take the people.

"I know they are all in the fire brigade comprehensive training center, and they are doing fine operation training." Gao Sheng replied, and without waiting for Qu Sen to ask, "My team and I are here today to "visit" the neighbors of your group."

"Why are you thinking about the little play of the technical listening team?"

The "neighbor" of the drone research and development team is a research and development team that specializes in developing and improving various surveillance and listening equipment. So when Gao Sheng mentioned it, Qu Sen immediately understood his purpose.

"The bureau has agreed to use personal methods to Wu Entai. I'm here to find out. I'm going to choose the good things first, and then let our bureau chiefs use the report."

Gao Sheng cannot directly call things developed by the Investigation Technology Innovation Group. If you want to use them, you have to apply with the "715 Working Group" just like the Huacheng Bureau used to call the drone.

Gao Sheng came to the technical innovation team many times and was very familiar with the people in each group. After taking Jia Chengliang to wander around the technical listening equipment research and development team, he secretly recorded what he might have used in the operation and quickly withdrew.

This kid is moving fast. Before he could get off work in the evening, the technical support application issued by the Huacheng Criminal Police Brigade and the Drug Enforcement Brigade passed the approval of the working group.

Although Gao Sheng wrote the drone team together in his application, the drone reconnaissance support for the mission is not needed for the time being. Qu Sen and the people in the group took advantage of the time to continue to improve the paper details. After the collection, Qu Sen sent it to Professor Wu via email.

After the email was sent out, it could not be so silent. Qu Sen called Professor Wu to express his gratitude.

After calling, I found out that Professor Wu had arrived in Huacheng last night and is now in the communications team to follow up on the two tests of battlefield tactical interference and battlefield communication relay.

Qu Sen knew about this, so Maliu said hello to Huang An and drove the car to the communication group directly.

After another rigorous inspection and registration, Qu Sen was taken to the military compound by Zhou Li. As soon as Professor Wu was not busy, he explained to him the discussion direction of the paper and the arguments involved.

Professor Wu's office had a computer that could access the external network, and he lowered the details from the email attachment. The old man cooperated with Qu Sen's story and marked it.

This is Professor Wu’s habit. When discussing problems with him, he will not interrupt you in the middle. Instead, based on your statement, first mark all the omissions and areas that need to be modified or enriched. After you finish explaining, you will tell you item by item.

Of course, when he speaks, you should also keep the questions you want to ask for in your heart, and wait until he finishes his talk, and then ask for advice one by one.

People who are just beginning to come into contact with his communication methods may not be very used to it. But after getting used to it, you will find that this is a very efficient communication method.

Zhou Li and Li Ying sat aside and listened for a while. When it was the turn of the two of them to work, they went out quietly.

The two of them had a round of Q&A in the office. When it was Professor Wu's turn to speak again, before he could speak a few words, Professor Wu's speech suddenly slowed down a little, and Qu Sen looked back along his gaze.

Through the glass partition in the office, I saw two policemen coming into the large office outside. It seemed that they were asking people outside. However, Professor Wu just took a look and quickly withdrew his gaze and his speech speed returned to normal.

No matter what the two policemen came outside, they had nothing to do with Qu Sen. So he immediately retracted his attention and continued to listen to Professor Wu's story.

Professor Wu spent nearly twenty minutes answering Qu Sen's questions. Just as Qu Sen organized the language and planned to ask questions in the second round, the office door was knocked.

Qu Sen was interrupted just as he was about to speak. When he looked back, he saw that Director Nie and a policeman from the test team were standing outside Professor Wu's office, so he got up and went to open the door.

"Professor Wu, I'm sorry to disturb me. This policeman, please look for Qu Sen if you have something to do." Director Nie is a good-looking person, and he is extremely polite to experts of Professor Wu's level.

"Oh, go, let's continue if you have time." Professor Wu thought the police came here and was working with Qu Sen. He considered that the other party came here to find someone. There must be something urgent and didn't care too much.

The policeman standing beside Director Nie nodded and greeted Qu Sen, then pointed at Director Nie's office, which was separated from Professor Wu's house, and signaled Qu Sen to go there to speak.

During this period, Qu Sen has always cooperated with the Huacheng police's big and small tasks, and no matter whether he is familiar with it, he has met many policemen. However, he is very sure that he doesn't know the person in front of him.

However, seeing that the other party wanted to talk to him privately, he didn't immediately ask. He followed the policeman into Director Nie's office.

After the two entered the house, the police closed the door, took out the ID from their pockets and handed it to Qu Sen, and said with a smile: "I originally wanted to go to the 715 working group to find Team Qu, but when I entered the door to register, I happened to see your name on the registration book."

Qu Sen smiled politely, took the other party's ID, opened it and was stunned when he saw it.

Although the other party's ID is a police officer's certificate, the registered unit is Huacheng National Security Bureau. Its position is the deputy section chief of the External Relations Department. Its surname is rare, and its name is Lan Jun.

"Hello Chief Lan." Although Qu Sen was confused, his face calmly shook hands with the other party.

"Please sit down and talk." Section Chief Lan reached out to signal the reception sofa in the office.

When Qu Sen sat down, he saw another policeman and Zhou Li and Li Ying entered the large office together and walked towards Team Leader Nie's house.

Seeing that the two Guoans were not looking for him alone, Qu Sen did not rush to ask, and waited for Zhou Li and Li Ying to enter the house.

After the five people were done separately, Section Chief Lan spoke first: "This time I found three people, because I wanted to do a routine inquiry. If there is any need, it may be necessary to cooperate with the three."

Qu Sen looked at Zhou Li and Li Ying next time, and saw that the two girls were confused like him, and said politely: "It is our responsibility to cooperate with the work of the National Security Department. Section Chief Lan has any questions if you need to know."

"Thank you!" Section Chief Lan said with a smile, then took the bag from another policeman, took out three photos from it, and lined up them up on the coffee table, asking, "Do you all know Zhang Yuanzhi?"

When Qu Sen heard Zhang Yuanzhi's name, he had already recognized the person from the photos on the table. The three photos were photos of Zhang Yuanzhi wearing a civilian military uniform and wearing a suit that did not look very high-end.

There is also a long-range photo of him wearing casual clothes, and the bridge of his nose also has the frameless glasses that Qu Sen had just seen a few days ago. It should have been taken recently.

"He was a software engineer before our May 11th. He officially transferred to the industry at the end of last year. Because I was not in the unit while I was still studying, I only found out about his transfer when I returned to the unit later.

We didn't contact each other until we met by chance at Yuejiang Wharf a few days ago." Zhou Li answered first.

"My mentor worked with May One before, and Zhang Yuanzhi visited the school with the leaders of their office.

He and I met at that time, but he quickly withdrew from the project team because of some things and never contacted him again. The last time he met was at Yuejiang Wharf." Li Ying also answered after Zhou Li.

Qu Sen was a little confused at the beginning, but later he saw Zhang Yuanzhi's photo and made a rough judgment in his heart.
