Watching the two of them enter the classroom, Su Runrun achieved the purpose of her trip and left the school on her tricycle.

It was already past 3 p.m., and there were not many people on the streets outside, with people going to work or school.

Su Ruanruan was riding a tricycle on the road, not going very fast, and subconsciously looking left and right.

But while riding the bike, Su Runrun's eyes suddenly fixed.

Near the post office in front, there was a man wearing a hat, looking around.

There was no anxiety or panic on his face. Instead, he seemed to be eagerly waiting for something.

At the same time, the whole person is in a defensive posture.

After just one glance, Su Ruanruan felt that there must be something wrong with him.

This was not just an intuition, but also a conclusion based on everything Fu Wenjing had taught her before.

Su Ruanruan did not stop immediately. She continued to ride the tricycle leisurely, passed by the man, and turned a corner not far ahead.

Su Ruanruan rode all the way to an empty alley, got off the tricycle, and put it into Tao Jinjin's warehouse.

Su Ruanruan did not go back immediately, but quickly went to the public toilet, changed her clothes, put on makeup, put on a wig, and wrapped a headscarf.

At this moment, Su Ruanruan looked like a woman in her forties or fifties.

She is still a woman who has been weathered by wind and sun.

Su Ruanruan walked out of the public toilet carrying a basket and walked slowly towards the post office.

I was worried that the man had already left, but I didn't expect that he was still standing there, still looking the same.

Su Ruanruan calmly withdrew her gaze and walked towards the post office without stopping.

When passing by the man, he subconsciously turned his head to look at Su Ruanruan, but he only glanced at her and quickly looked away.

Su Ruanruan entered the post office and stood at the counter, staring at the stamps and envelopes inside.

It looks like it is picking something, but in fact it is keeping its ears perked up, paying attention to what is happening outside.

Occasionally, Su Ruanruan would turn her head, her eyes quickly sweeping over the man, and then quickly retracting them.

After selecting for a long time, the man outside didn't make any move, and the staff inside the post office became a little impatient.

"Auntie, you've been standing here for a long time. What do you want to buy? If you have nothing to do, please go out and don't delay our work."

Although Su Ruanruan put on old-age makeup for herself, there was no flaw.

But she had no way to change her voice, so she could only pretend that she couldn't speak. She pointed to a stamp on the counter and made a number one with her hand.

The staff member was stunned for a moment, then blushed instantly.

"Auntie, you can't speak, I'm sorry, I don't know.

You want a stamp? I'll get it for you right away."

Su Ruanruan successfully bought a stamp and an envelope, but there was no reason for her to stay here any longer.

Just as Su Ruanruan turned around and was about to walk out of the post office, a short man hurried in. He ran to the man and stood on tiptoe to whisper a few words in the man's ear.

The man nodded after hearing this, and the two of them walked in another direction together.

Perhaps because they didn't want to attract too much attention, the two of them didn't move very fast.

Seeing this, Su Ruanruan no longer hesitated and followed quickly.

They quickly walked from the wide road into the narrow alley.

Su Ruanruan didn't dare to follow too closely, for fear of attracting the attention of the two people in front.

Fortunately, the two people in front were on their way. They would occasionally talk to each other and never looked back from beginning to end.

After walking around in circles for a few minutes, the two finally stopped in front of a dilapidated yard.

Watching them enter the yard, Su Runruan frowned tightly.

Could it be that these two people are doing business in the black market?

Although this county town is very close to the military area, there is a black market wherever there are people.

Especially in this era when it is not very convenient to buy anything, some people have supplies but no money, while others have money but cannot buy anything.

As more and more people like this emerged, a black market naturally emerged.

The people above are not completely unaware of this, but even if the black market is banned, it is impossible to completely eliminate it.

As long as the trouble is not too serious, the higher-ups will turn a blind eye, except for a major raid once in a while.

People who do business in the black market like to find a shabby and inconspicuous courtyard in such a remote alley to store things or conduct transactions.

Su Ruanruan had discovered this more than once when she came to the county town with Fu Wenjing.

The two men had no shortage of money or supplies, and had no interest in the black market or in reporting it. They just took a look and left.

Now seeing the two people entering such a small courtyard, Su Runrun's first reaction was that they were also dealers in the black market.

But soon, Su Ruanruan heard some unusual noises coming from the yard.

That's someone fighting!

Although there may be occasional conflicts when doing business in the black market, everyone is only trying to make money. Unless it is absolutely necessary, things will not get to this point and it is impossible for them to fight like this.

Su Ruanruan, who had just suspected that she wanted to fall, instantly realized that she was right.

Su Ruanruan looked around and saw that there was no one there, so she quickly opened the gold rush shop and bought a series of things including electric batons, stun guns, nail guns, etc.

Electric batons and stun guns can only be used at close range. Although the power of nail guns is not very great, they can attack at a slightly longer distance.

Su Ruanruan couldn't buy a gun on the gold rush, so she had to make do with this.

Su Ruanruan held a nail gun in her hand and gradually approached the yard.

Just as I reached the door, I heard a muffled groan from inside.

Even though the voice was not loud and was very short, it was too familiar. Su Ruanruan instantly recognized it as Fu Wenjing's voice.

Wasn't Fu Wenjing on a mission? Why was he here?

He sounded like he was injured just now. Is it serious?

In just a moment, all kinds of questions appeared in Su Ruanruan's mind.

But Su Ruanruan knew that now was not the time to think about these things.

Tightening the nail gun in her hand, Su Ruanruan moved closer to the crack in the door to take a look at the situation in the yard.

I saw two people standing in the yard, they were the two men just now.

There was also a person lying on the ground, it was Fu Wenjing.

Just as Su Ruanruan looked over, Fu Wenjing also looked over, and their eyes converged in the air.

Just like Su Ruanruan recognized Fu Wenjing by a muffled groan, Fu Wenjing also recognized Su Ruanruan by a glance.

Fu Wenjing blinked and began to make gestures to Su Ruanruan calmly.
