"Yes, the board. As soon as I went up, I saw that there was still a tail left on the board. When I looked carefully, it had already been pulled up. I was afraid of being discovered, so I hid in the bathroom. I didn't come out until there were footsteps coming downstairs from outside."

"Where did you see that man go?"

"No, that person was wearing a mask all the time and was gone when he came out."

Li Xuewu had been staring at Hu Zhengquan just now and didn't pay attention to anyone coming out of the club.

"It's okay, I probably didn't notice you. Are you hungry? I left some sweet potatoes for you."

Li Xuewu comforted the trembling Liu Zhaolun and handed him a sweet potato.

Liu Zhaolun took the sweet potato and squatted on the ground to rest for a while before starting to eat.

Li Xuewu looked at the third floor of the club and Hu Zhengquan's house in confusion, wondering what these people were up to.

It's really cold today, it's past 10 o'clock now, and the moon is so high.

The heat from the sweet potatoes I just ate was gone.

Seeing that Hu Zhengquan's house turned off the lights and the club also turned off the lights and closed its doors, Li Xuewu and Liu Zhaolun pushed the car back. After walking a few steps, they heard a "Boom!" sound coming from behind.

Li Xuewu instantly turned around and looked in the direction of the sound, but saw nothing.

But the voice did appear behind me, and it was very crisp and loud in the silent night.

Seeing Liu Zhaolun also looking confused, Li Xuewu knew that he was not hallucinating. It seemed that the fox had already taken action.

Li Xuewu winked at Liu Zhaolun, and the two of them continued walking back. Since there was nothing they could do to check today, they could only wait until tomorrow.

Li Xuewu is good like this. Since there is no way to investigate, then give up quickly to avoid catching the fox and causing a lot of trouble.

The two of them rode back to the steel rolling mill and went to the escort dormitory to wait for Xu Ning and the others.

About two hours later, Xu Ning and Han Yating came back.

Li Xuewu led the five people to the auxiliary building office for a meeting.

As soon as he sat down, Xu Ning said: "The people I followed entered the foreign affairs department's residential area and waited for a long time but no one came out."

After listening to Xu Ning's words, Han Yating continued: "The people Xu Ning was talking to had chatted with several foreigners. Although Hu Zhengquan was not approached directly by them, they also had interactions."

Li Xuewu nodded and motioned for Han Yating to continue.

"The people I talked to were all professors at Huaqing University. The two who talked to the target the most were old professors in their 50s who lived in the residential area here."

Li Xuewu threw cigarettes to Xu Ning and others, and after they all lit them, he asked: "How old are you?"

Han Yating said with certainty: "The two younger ones got out of the car first. I took note of the house number. The two older ones lived further away. I also looked carefully and saw that the car seemed to be a personal vehicle, so I parked it.

Downstairs, I focused on these two people."

"Hmm." Li Xuewu knew what Han Yating meant. Just look at the windbreakers and woolen coats these people wore.

Han Yating said: "These two people had long exchanges with Hu Zhengquan at the club, and our investigation also showed that Hu Zhengquan has professor friends in Huaqing. I doubt they have any purpose in meeting here."

Li Xuewu flicked the cigarette ashes in his hand and kept thinking in his mind that he seemed to have gotten involved in some terrible circle.

How could it be so big and how could an engineer have such complex social relationships and yet be able to withstand constant scrutiny?

But it didn't feel right. How come it was such a coincidence that he had to catch up with the meeting that he was following? Li Xuewu didn't believe that he was the favored man of heaven and the son of destiny.

Seeing Li Xuewu thinking, several people stopped talking and looked at Li Xuewu quietly.

After a moment of reflection, Li Xuewu said: "It's very late. We have to go to work tomorrow. Let's not think about it anymore. Let's rest first. Tomorrow, Xu Ning will go and see if there is a room nearby that can be rented to observe the target. It's too cold like tonight.

It’s inconvenient and cannot be monitored for a long time.”

Xu Ning agreed. Seeing that Li Xuewu had no other instructions, they said goodbye to each other and left the conference room and went downstairs.

Only Li Xuewu was still smoking and thinking about something in the conference room.

Foreign embassy, ​​university professors, engineers, what the hell, academic exchanges?

Damn! There must be something wrong. How did these unrelated people get together? Why?

I put out my cigarette butt in the ashtray, turned off the lights, and went downstairs to rest in the guard dormitory under the cool moonlight.

When Li Xuewu got up the next day, his nose was a bit stuffy. It seemed that he had caught a cold due to the cold last night.

I did morning exercises with the guards, ran around the steel rolling mill, went to the canteen and drank a big bowl of porridge, sweated all over, and felt better.

Li Xuewu went to the archives of the steel rolling mill to find some materials, and then went to the kennel. When he returned to the office, he saw that Han Yating and Xu Ning were not there, so he returned to his office.

I took out the reference materials I found on my eldest brother's bookshelf, based on the information I found in the archives, put on my gloves and wrote a document. I also used a ruler to compare and draw, and then put it in a moist document bag.

, went to Dong Wenxue’s office on the main floor.

Dong Wenxu was answering the phone when he saw Li Xuewu come in and waved for him to sit down.

After Li Xuewu sat down, Dong Wenxue chatted for a few more words and then put down the phone and asked: "What's wrong? I'm carrying a document bag again."

Every time Li Xuewu makes a big move, he will bring documents over. This is a habit Li Xuewu has developed. It is best to have information and data support when reporting work, so that leaders can intuitively feel his work attitude.

"

Last night I led people to start a rat extermination operation. Rats are very cunning and cautious. I couldn't sleep because of my thoughts last night. It was almost dawn and I came up with a bad idea. Please give me some advice."

Li Xuewu really thought about it a lot. The more he thought about it last night, the more he couldn't sleep. He was always thinking of ways to find this person out, but when he saw that this person was not moving, he was very discouraged.

This is still a solution that I came up with after thinking about it for half a night.

"Oh? They say it's a bad idea. You must be holding it back so hard." Dong Wenxue took the folder handed over by Li Xuewu and looked at it.

The sight of this made me break out in a cold sweat, and I asked anxiously: "Where did you get this?"

Dong Wenxue pointed at the title on the folder and glared at Li Xuewu.

No wonder Dong Wenxue was anxious, what was written on this folder was "Report on the Material Demonstration of Carrier Wings of Project 639405". It was a document compiled by Li Xuewu in Martian script that would be familiar to later generations. It was written according to the format of the archives materials.

A stack, a dozen articles.

What worried Dong Wenxue the most was that he couldn't understand it. All he could understand was the code name "639405". The design drawings looked messy, but to the naked eye they looked like mushroom eggs. They looked very sci-fi and seemed to be still being revised.

Li Xuewu pointed to the word "Heizi" and asked, "Are you familiar with it?"

Dong Wenxue looked at it and asked, "That dog?"

Seeing Li Xuewu nodding, he asked again: "What does this mean? These words seem to be Chinese characters, but they are not Chinese characters."

Li Xuewu chuckled and said: "I encrypted a British mushroom cloud design article translated by the archives, and wrote a police dog training outline according to the numbers and format. This kind of writing is what we want to have that sense of plausibility.

, I exaggerated and changed the drawings randomly, and I didn’t draw anything that was too precise. This is just a preliminary plan, for catching mice, and it is processed by tracking sensors."

Dong Wenxue threw the documents on the desk and said: "You are not afraid of causing a big mess. If something goes wrong, you are not afraid of being dealt with. And is there any tracking sensor here?"

Li Xuewu saw that the teacher was still flipping through the documents. He got up and went to the door to get a towel and handed it to Dong Wexue. Dong Wexue took the towel in confusion and then said what "tracking induction" was.

Before Dong Wenxue finished listening, he put a towel on Li Xuewu's face. Li Xuewu reached out to catch it and handed it back with a smile.

Dong Wenxue pushed the document in disgust and said, "Put it away quickly, why didn't you tell me in advance?" After saying that, he wiped his hands with the towel handed over by Li Xuewu.

Li Xuewu smiled and took out his gloves from his pocket, put them on, packed up the documents, and followed Dong Wenxue's instructions to seal the document bag and stamp it with the official seal of the Security Office.

"Okay, get out of here, I'll find someone to take care of the rest."

Seeing that Li Xuewu had finished, Dong Wenxue threw the towel into the basin, came back and cursed at Li Xuewu.

Li Xuewu said unconcernedly as he walked out: "You know who to give it to, right?"

Dong Wenxu pretended to kick Li Xuewu, but when he saw Li Xuewu ducking away, he cursed: "I still need your teaching, get out!"

Seeing that Li Xuewu was about to leave, he looked at the documents on the table and called out to Li Xuewu: "Leave the gloves."

Li Xuewu strolled to the office. He was on duty yesterday, so he just had to work the morning shift today. After finishing the work, he could go home and rest after having lunch.

Just before get off work in the morning, Xu Ning came over to report that the surveillance location had been found. It was on the second floor of a bookstore. The bookstore closed at 6:30 pm, and Li Xuewu and the others could use it until it opened at 8:00 the next day.

Of course, you can only borrow the room and cannot touch the things inside. Xu Ning also relied on his own connections to make it happen.

"Be more prepared this time. Bring a high-magnification telescope, hot water, food, notebooks, and a few more people. We will keep an eye on him from tonight on. I don't believe he won't come out for activities. Let's do it for Gao Fengkun and Liu Zhaolun.

With an identity, let them go in and look around every night."

Li Xuewu knew that nothing would be found in this kind of case without any effort, especially for an old man like this, who had been wandering in the world for a long time and had his own set of prevention systems. He had to carefully remove the external cover.

Only then can we see through its essence.

"Understood. I'll go to the cafeteria tonight to prepare some more food, and then go to the warehouse downstairs to get the high-powered telescope."

Xu Ning was just about to leave when he was stopped by Li Xuewu: "Wait a minute, don't go to the canteen, buy it outside, and then write it off when it's certain. The same goes for the telescope. I'll write you a note. You go to our police station over there."

borrow"

Xu Ning was stunned and asked in confusion: "Section Chief, what do you mean?"

Li Xuewu shook his head and said: "I didn't say anything. Without evidence, everything is just speculation, but we must guard against this kind of speculation."

Xu Ning asked: "Are you saying that there were internal reasons for the failure of previous explorations?"

Li Xuewu nodded and said: "I don't believe that the people who investigate him are useless snacks, and I don't believe that he has three heads and six arms to guard against everyone, so there must be someone we can't guard against who is tipping him off."

Xu Ning nodded and said: "I understand, what about Gao Fengkun and the others?"

Li Xuewu waved his hand and said: "Don't worry, these people are all from Hongxin Commune and there will be no problems. Also, they don't come into contact with many people. They have been living in the guard dormitory. There is also the relationship between Zhao Yajun and me."

, others may also go to my house.”

Xu Ning took the note written by Li Xuewu and went out. Li Xuewu stood up and walked to the window behind him and looked towards the laboratory building. There was a window there that was Hu Zhengquan's office.
