Tracking this matter is by no means something ordinary people can do, and this is a forbidden area for non-professionals.

First of all, in this era, people's horizons are not broad, and they are only accustomed to the existence of blending with the scene. For example, if you enter a slum in a suit and wear black shoes on a dirt road, you will definitely be noticed.

What's more, Bai Ling is a woman who knows her identity very well, and she knows that she is always vigilant, and she can follow her footsteps in this situation, and she does not appear abrupt in the surrounding environment, and is not noticed, which can only be done by professionals.

Moreover, it can't be a professional, it has to be a group of people working together.

Thinking of this, Xu Ruifeng stopped Bai Ling when she changed her outfit and was about to go out.

"Still going out today?"

"Ahh Bai Ling replied and explained.

Xu Ruifeng couldn't help but wonder: "What are you doing these days when you are walking out so endlessly, is it necessary to explain it to our brothers?" ”

Bai Ling explained: "The Harbin Municipal Party Committee is conducting patriotic education for grassroots cadres, with the aim of cultivating underground party members with strong convictions and making them aware of the importance of upholding their convictions in a difficult environment. So, I want to find a colleague who is carrying out the task of hoeing and raping to teach progressive students and teachers......"

"So they hired you?"

"yes." Bai Ling said proudly.

Regarding being invited, Xu Ruifeng can understand. There is such an underground party who is on a mission and has experience in hiding behind enemy lines to teach students, and when Miki is killed and Bai Ling and they are all on the wanted list, that kind of shocking effect can make the students' hearts change drastically. Everyone who sees the wanted notice will feel the firmness of our party's underground workers, and even more a sense of worship for the influential figures.

However, you can't hurt your companions on a mission just because you train a new person, right?

Xu Ruifeng continued to ask: "On the way to teach students in the past few days, has there been anything special happening?" ”

Bai Ling's hand had already opened the courtyard door, and when he heard this, he turned around and closed the courtyard door: "Old Xu, did you see something?" ”

"You talk about your feelings first!"

Bai Ling thought for a while and said: "The day before yesterday, I always had a bad feeling lingering in my heart, and I always felt as if I was being followed, but behind me, there was no familiar face. So, I had an extra eye and started wandering around Harbin, but the feeling quickly disappeared......"

"These things are very careful."

Xu Ruifeng continued: "How long has this feeling lasted? ”

Bai Ling stretched out a finger and said, "Only this time." ”

"I still think I'm thinking too much, but you're really a little flustered when you ask this question today."

Thinking too much?

All the feelings of the underground intelligence officers are not groundless!

Xu Ruifeng said in a stable mood: "Listen, you have been followed, the children in the next yard have seen people following you several times, but you didn't see it." ”

"It can't be!"

"How could it not be? If people are willing to guard against you, no matter how sensitive you feel, all you see is the emptiness behind you. But the stalker couldn't keep everyone's eyes out, so the little guy next door could see it. Bai Ling, you can be lucky, if I hadn't seen this kid squatting at the door crying this morning, and one more mouth, the entire underground party members in Harbin would have died in your hands. ”

Xu Ruifeng stretched out his hand to open the courtyard door, and Bai Ling was surprised: "What are you doing?" ”

"What?" Xu Ruifeng said: "What do you usually do today, you remember, whether you notice that someone is following you behind you or you feel that the stalker is disappearing, never let people see the clues, do what you usually do today, leave the rest to us, now, go out immediately." ”

Xu Ruifeng pushed the dressed Bai Ling out of the courtyard door, and then closed the door and shouted: "Wang Ming, Sibaozi, old smoking gun!" ”

The words fell, and the three of them walked out of the room one after another, Lao Xu stretched out his hand and took out a gun from the firewood stack in the courtyard and distributed it and said: "Listen to it, fall far behind Bai Ling in different areas, alternately cover forward, and find the person who is following Bai Ling, you are not allowed to move, you are not allowed to make a sound, and you are not allowed to follow you, remember the person, remember the look, see me passing by you, and immediately point it to me." ”

"Do you understand?"

All three nodded at the same time.

Xu Ruifeng waved his hand: "Let's go!" ”

The three of them took to the streets at the same time, and the first wave was Wang Ming.

At this moment, Bai Ling, as usual, walked forward slowly with the footsteps of the crowd on the street corner with his handbag in both hands.

What she thought was, "I'm really being followed?" Will it be a special high class? Or someone from another organization? What is his purpose in tracking himself? Just to arrest the underground party in Harbin? ”

As soon as my mind was confused, my steps were naturally chaotic, and I walked to the station, and when the train came, I raised my legs and stepped onto the train.

Seeing this, Wang Ming silently followed behind him and followed through the back door of the tram, and at the same time, he watched a guy in a black suit with a newspaper under his armpit following Bai Ling.

This is the second person Wang Ming saw, following behind Bai Ling. This group of people is very skillful in tracking, if you don't notice any behavior, they will follow steadily, once nervously turn back, the stalker will walk forward with firm steps, and there is no one like you in their eyes, walking past you.

It's as if tracking never existed.

When the suspicion on your body passes, in the alley, in the corner, there will be another figure, and continue to follow the past so ghostly.

All this is vague to the person being followed, but to the person who fell behind Bai Ling and watched it coldly, it was extremely clear.

After getting off the train, Wang Ming had just followed Bai Ling from the center of Harbin to the outskirts of the city, and immediately saw Xu Ruifeng waiting at the station, he was far away and stretched out his hand to point to the man in a black suit behind Bai Ling, and after seeing Xu Ruifeng nodding lightly, he turned into the alley.

The old smoking gun, in this place full of countrymen, held a dry tobacco bag, hunched his back, and followed slowly, like an old man buying vegetables in the vegetable market, without any flaws.

At this moment, Bai Ling couldn't bear the psychological pressure and glanced back, and her feeling of being followed behind her appeared again. The moment he turned around, the stalker who was following him stood out like a flock, dressed in a suit and standing in the world full of countrymen. But he was not nervous, and passed by Bai Ling in the crowd, not looking at anyone at all.

"Don't be blind, go yours."

It wasn't until Bai Ling heard this voice so low that only he could hear it that he found that Xu Ruifeng had already walked past him, and he just followed the man in the black suit and walked forward quickly, turned right at the intersection in front of him, and disappeared without a trace.
