On the streets where people were coming and going, the postman rode a bicycle to pass by Yuan’s house quickly, and there was no stop during this period. It was obvious that Yuan Chuyu’s letter had not been sent or the place where he was sent was not Yuan’s house.

Behind the postman, a middle-aged man wearing a gray royal blue cotton jacket, black cloth shoes, and white cloth wrapped in toe, suddenly stopped and turned to look at the courtyard at the corner of the street.

Perhaps he had noticed something, the man looked suspicious and hesitated for a while and headed straight to the courtyard. By observing Kong, Wu Chunyang and others clearly saw this scene.

It was at this time that the spy present discovered that the other party's body shape and some facial features were very similar to one of the four suspects.

Faced with the emergencies, the spies seized the time to take a few frontal photos, and then picked up a wedge from under their feet to block the observation hole, and the wall instantly returned to its original state.

Wu Chunyang pulled out the gun, but did not pull the sleeve, but closed the safety and directly pulled the trigger, quietly loading the gun. The advantages of PPK's linkage structure were undoubtedly revealed at this moment.

The little spy next to him also loaded and stood against the wall. The muzzle was slightly offset and aimed at the position of the visitor.

Outside the wall, the middle-aged man took off his shoes and knocked the mud in his shoes. He sat down by the roadside, and his head gently turned towards the courtyard wall.

The traditional houses in the mountain city have mostly walls of bricks or rammed earth, with uneven surfaces. This yard is no exception. The earth wall mixed with straw is about one meter high and covered with gray tiles.

This kind of wall may be able to block the thief, but it cannot block the 7.65mm pistol bullet. No matter how powerful the pistol is, it is a hot weapon. It is easy to penetrate the earth wall at such a close distance.

Suddenly, the middle-aged man seemed to have discovered something, his eyes approached a pit on the wall, and poked the surroundings of the pit with his fingers.

His forehead was tightly attached to the earthen wall. On the other side of the wall, Wu Chunyang's muzzle was pressed against the wall, and his right index finger was pressed on the trigger, and the situation was about to break out.

Da...da...da...da...

The watch pointer was beating, Wu Chunyang slowed down his breath, put his left hand beside him gestured, signaling his subordinates not to move, and at the same time activate the response measures.

A moment later, a strange creaking sound came from the opposite side of the road. The middle-aged man quickly retracted his head and continued to sit on the side of the road as if he was resting.

A young woman holding a wooden basin appeared outside the yard door opposite. She glanced at the middle-aged man, raised her arms and poured the sewage in the basin to the ground, and greeted the passerby neighbors.

Seeing this, the middle-aged man let go of his frowning brows, got up and patted his P-thighs, leaving without looking back.

After a few minutes, Wu Chunyang opened the insurance and put the gun back into the holster, and whispered to the little spy.

"Tell brothers outside to keep a distance and not to be exposed."

The little spy nodded, quickly left the yard through the back door, quietly integrated into the pedestrians, and chased in the direction of the middle-aged man leaving.

As early as the beginning of the establishment of the surveillance site, Wu Chunyang considered various possibilities and deployed multiple mobile forces nearby to prevent such a situation just now.

--------------------------------------------------------------------------------------------------------------------------------

A market in Shancheng.

The middle-aged man left Yuan's house and came here, wandering around aimlessly. From time to time, he stopped to pretend to select goods, and observed the situation around him from the corner of his eyes.

Around him, several spies pretended to be customers and buyers hiding in the market, keeping a distance from the target at a distance, and Wu Chunyang, who had changed into a dress, was also among them.

Everyone's eyes occasionally meet and exchange information tacitly. After so many years of practical training, Yida has extremely rich experience in tracking.

When should be hidden, when to leave, and when to take over, there is no need for Wu Chunyang to remind the operators to judge by themselves.

After walking for a while, the middle-aged man looked up at the sky and walked out of the market quickly. When he walked out, he did not forget to observe whether anyone was following him.

A few dozen meters away from the middle-aged man, Wu Chunyang stood up from a stall and looked around, and said to his subordinates with a slight movement of his lips.

"Let the brothers not move first, the target will be the responsibility of the reception staff, and we will withdraw in batches."

"Yes, Director."

The spy took the order and left, and the market was still crowded with people. Vendors shouted and shouted, while customers were picking and picking. No one noticed that more than a dozen people were missing.

Besides, middle-aged people, after leaving the market, they formed a circle in the urban area and used the stairs that could be seen everywhere to go up the mountain and sometimes go down the mountain.

The spies looked at the target that was the same way and crossed the road, and cursed in their hearts.

Compared with plain areas, the tracking mission of Shancheng is extremely difficult, especially when facing a professional agent, if you follow too far, you will lose your observation field, and if you follow too close, you will easily be exposed.

Wu Chunyang, located behind, decisively adjusted his tracking plan, gave up relying on reconnaissance, spread all his hands, and grasped the target's movement trajectory through controlling intersections and bridges.

The operator rolled forward with the goal as the center of the circle. No matter which direction the other party is walking, they cannot escape the spy's eyes.

Even if the target disappears in a certain area, this method can be used to quickly lock the specific position, and it will be simple to catch turtles in the jar.

The only disadvantage of this method is that it requires a large number of personnel and is a veteran who is proficient in tracking, because when facing the target, newcomers can easily reveal flaws.

As the ace unit of the Military Control Commission, there is naturally no shortage of elite agents. Under the command of Wu Chunyang, the middle-aged man has never been able to escape surveillance.

Time passed slowly, and the sun rose to the highest point of the sky. The spies followed the target from the south to the north of the city, and then from the north to the east of the city. But judging from the other party's appearance, the game of cat and mouse would not end for a while.

Outside a hidden alley in the east of the city, two small spies who had met the target quickly entered the alley, turned over and climbed onto a truck, and began to change their facial disguises and clothes.

“Get new shoes and fake toe covers.”

In the carriage covered with tarp, the makeup artist urgently ordered the assistant to draw the eyebrow pencil on the face of the little spy, but with just a few strokes, the little spy seemed to have changed.

There are two or three pairs of similar combinations in the carriage. All spies who have been exposed have changed their appearance here and are responsible for monitoring the outer enclosure after they go out, so as to minimize the possibility of being recognized by the target.

At this time, there were four such makeup cars on the streets of Shancheng, which were the most powerful and important guarantees for the operators.

After putting on makeup, the little spy had a meal, got off the car and devoted himself to work again. According to the frontline notification, the target was having a meal in a teahouse.

The mountain city has produced tea since ancient times, and the tea style is very prosperous. The gathering of capital, market and personnel in wartime has given birth to a large number of teahouses.

These teahouses vary in size, with dozens of tables, and only half of the small ones. The business contents are also different. Some only sell tea, while others also provide catering and accommodation.

What middle-aged people go to is a large teahouse with hundreds of seats and can order dishes. Although it is noon, the teahouse is still full.

"Please inside the guest."

The teahouse waiter (mate) enthusiastically welcomed the middle-aged man into the store, and then wiped the table and chairs with a hand towel to ask the other party to sit down and ask what he needed.

The middle-aged man looked at the customers in the store and gave tea materials first, and ordered a few things in the skillful Shancheng dialect.

"Put a bowl of Tuo tea, and then add some sunflower seeds, pumpkin seeds, and beans. The tea must be hot."

"Okay, wait for the guests."

The waiter swung his hand towel to the back hall, and slogans such as "No loss of things", "One bowl per person, paying hygiene", "There is always no air strikes, and the guests paying for tea in advance", and "National Defense Secret Talk" were hung on the wall.

Therefore, if someone does not pay first after entering the teahouse, he must be a foreigner. This is like the British looking at the right and then the left, which are both behavioral habits with great regional characteristics.

"Beware of boiling water~"

With a shout, the waiter came back. He held a long-mouthed copper teapot in his right hand and a tea set and snacks in his left hand. He arrived at the table and arranged the tea set and rinsed the boiling water into the tea bowl.

The middle-aged man nodded, picked up the tea bowl and took a small sip along the side of the bowl. Tuo tea tasted bitter but was cheap and very resistant to soaking, and was very popular among the people at the bottom of the mountain city.

After drinking the hot tea, the middle-aged man's face turned blue by the cold wind and turned red in an instant, and he seemed to have come alive. Only then did he have the time to carefully observe the people in the store.

"Son of Turtle, do you recognize me as someone? I will accompany you wherever you go."

"Drink tea, drink tea."

In the teahouse, there were constant noises, laughter, conversation, and scolding. Wearing various clothes, tea guests of different identities lived in the same room, which was very lively.

Before the middle-aged man could take a second sip, a girl selling candy and fried chestnuts came beside him, followed by an old woman selling dried fruits and dried meat foods... After a while, another fortune teller with a glass sign walked in from outside the door.

He sent the old woman away casually, and the middle-aged man turned around with his small eyes, focusing on observing the fortune teller who had just come in.

I saw the other party walking around among the guests, chanting in his mouth that your seal hall will be prosperous soon and you will be prosperous and your ears will be blessed. This is a beautiful word of wealth and honor.

This person is thin, his cotton coat is shiny, his thumb is exposed on the tip of his shoes, a standard northern accent, and his speech is smooth and smooth.

There are many such scammers who fled in the mountains. There is nothing surprising about them. After hearing this, the middle-aged man turned his head and started drinking tea attentively.

He sat there for an afternoon and didn't leave until dark. The visibility of the mountain city in winter was very low, and with the air defense light control, he could no longer see his hand outside the teahouse.

Looking at the blurry back in the dark, Wu Chunyang immediately ordered to stop tracking. In this case, the probability of being discovered was too high.

The reason why the target stayed in the teahouse for most of the day was probably to wait for darkness and try to use low visibility to get rid of the tail behind him. This Wang Badan was quite cunning, but fortunately he made a second-hand preparation.

In the teahouse lobby, the waiter quickly took the tea bowls and chopsticks used by middle-aged people to the tray, ran to the back hall and said to the fortune teller.

"Sir, the thing is here, no one else has touched it except me."

"Well, remember, keep your mouth in mind, otherwise you and your wife and children will have trouble!"

After the fortune teller made his harsh words, he threw down a roll of banknotes, carefully wrapped the tea bowls and chopsticks into a cloth bag, and slowly left the teahouse.

That night, the Military Intelligence Department's technical department did not sleep all night. The technicians extracted several fingerprints from the bowls and chopsticks. After eliminating the waiter's fingerprint, a clear right thumb fingerprint pattern was sent to Wu Chunyang and Zuo Zhong's hands.
