Siheyuan: Returning from studying abroad, with extraordinary understanding

"Name!"

"Lin Changqing!"

"gender!"

"male."

"..."

A crude interrogation room in the Security Department of Tianjin Port.

After Lin Changqing was brought here, he was pressed onto an iron chair and his hands were tied to the armrests.

No matter how he explained, they still didn't stop.

Then, two interrogators came and started asking a series of questions.

"Lin Changqing, tell the truth!"

"What's your code name?"

“Who is online?”

"What's your purpose of coming back?"

"What did the note say?"

"..."

"Be lenient with confession, strict with resistance!"

"Comrade, I am not an enemy agent, I don't have a code name, and I don't know what to do online."

Lin Changqing met the two interrogators' sharp gazes and spoke calmly.

Knowing that he was innocent, he was no longer panicked.

"Tell the truth, don't rely on luck!"

Seeing that Lin Changqing refused to admit it and did not explain, the chief interrogator felt a little dissatisfied and his tone became heavier.

"I'm really not an enemy spy. There are documents in my suitcase that prove my innocence."

Lin Changqing emphasized again.

"We have already looked at the documents you brought and will naturally verify them clearly."

"Then tell me, what's the matter with that note?"

The interrogator had read Lin Changqing's information and was able to confirm Lin Changqing's identity, but he was unable to confirm his experiences in Eagle Sauce, his experiences in Hong Kong Island, and the people he had come into contact with.

The interrogators have extensive experience working behind enemy lines and know how to hide information.

However, they used several known methods but were unable to display the above content.

"I wanted to tell you about the note at the time, but I was arrested."

It was because of this note that he got arrested, and Lin Changqing was very depressed.

Without waiting for the interrogator to speak, Lin Changqing described in detail how he was hit in the crowd and what happened when he read the note.

"Did you see clearly the face of the person who hit you?"

"Remember, he's pretty easy to recognize."

Although it was just a casual glance, Lin Changqing was deeply impressed.

"Tell me more about it."

"Um...it's hard to describe, but I can draw it."

"It would be even better if you can draw it!" The interrogator was delighted and handed the paper and pen to Lin Changqing.

Lin Changqing took the paper and pen, thought about it, and started drawing.

Lin Changqing is not a professional in painting.

However, in the process of learning mechanical knowledge, he drew a lot of drawings, which gave him a certain foundation in painting.

When he was bored, he tried to draw a person, which was somewhat similar. He felt that he had a talent for painting, so he practiced for a few days.

So if you ask him to draw that person's appearance now, he can do it easily.

A few minutes later, the portrait was completed. Lin Changqing looked at it carefully and found that it was 80% similar to his impression.

That person has a very distinctive appearance, and you can basically remember him once you have seen the portrait.

"The painting is done!"

The interrogator took the portrait:

"Are you sure it's him?"

"Confirmed. By the way, this person should not have gone far. He squeezed to the back and may not have left the dock yet. However, I don't know if you alerted him when you were arresting me."

After hearing Lin Changqing's words, an interrogator immediately went to report.

.......

The interrogation ended and the other interrogator left.

Leave Lin Changqing in the interrogation room.

Thinking carefully about the interrogation just now, he was very cooperative during the interrogation and said whatever was asked.

It seemed like something was missing. Lin Changqing suddenly remembered that he did not seem to tell them how to display the contents of the note.

Let’s talk about it later. Seeing that there is no one around, he also wants to be quiet.

When Lin Changqing was studying chemistry abroad, he learned about some special chemical reagents that could hide information on white paper.

After writing and drying, no marks or odors will be left on the paper.

......

On the other side, the interrogator took the interrogation results and reported to the head of the Security Department, Liu An.

At that time, there was no police station yet, and all cases in Jingang were handled by the Security Department.

It is their duty to arrest people, interrogate prisoners, and detain suspects and criminals.

After seeing the portrait, Liu An immediately made arrangements to block the dock and arrest people.

The leader attached great importance to the enemy spy incident and asked him to get to the bottom of it as soon as possible.

He promised to give an explanation to his superiors within three days.

If it exceeds three days, he knows very well that he would be derelict in his duty.

There are so many people coming and going now that it will be difficult to catch anyone in a short time.

Even as the section chief, he couldn't arrest people that quickly.

After Liu An arranged the personnel, he did not let himself sit idle.

I took the note and observed it repeatedly, but I didn't find anything unusual. There was no special smell, and I soaked it in water and roasted it with fire, but the content did not appear.

This made him feel troubled.

His superiors attached great importance to it and asked him to solve the case as soon as possible.

At this time, he couldn't sit down at all and paced back and forth in the office.

He muttered to himself: "Lin Changqing...note...international student..."

Why give the note to Lin Changqing?

Questions linger in my mind.

Suddenly, he remembered that Lin Changqing was an overseas student and a senior intellectual, and perhaps he could find a way to make the note reveal its contents.

Thinking of this, Liu An walked towards the interrogation room.

In the interrogation room.

Lin Changqing saw another person coming and asked:

"Any questions? When can I get out?"

"Why aren't you afraid? Logically speaking, everyone who comes here will be a little scared." Liu An did not answer Lin Changqing's question.

"From what I know, you were very scared when you were arrested! Why are you so different now?"

Noticing Lin Changqing's calm demeanor, he became curious.

He was probably sure that Lin Changqing was not an enemy spy, but more because Lin Changqing was an international student, and the organization now attaches great importance to international students, so he asked this question.

"Of course I am afraid! How could I not be afraid when I was pointed at with a gun? Now, I have a clean background, so I am not afraid. Besides, you are all heroes of our Dragon Country, so why would I be afraid?"

Lin Changqing said calmly that although he didn't know who the person in front of him was, he guessed that he was a leader.

Being able to ask him this, Lin Changqing guessed that there was probably no problem with his identity.

This place has been liberated, so he is not worried about being tortured into confessing.

There is no need to worry. Just like before, if you are arrested for no reason, you will not be released unless you pay money.

This is what the yellow-skinned people did in the past, and the people at that time avoided them like the plague.

It’s different now, Lin Changqing is certainly not afraid.

The man in military uniform in front of him is the hero he admires in his heart!

"Hahaha!"

"I don't dare to be a hero, I just killed a few more devils."

When Liu An heard Lin Changqing's display, he felt proud and his liking for Lin Changqing increased a lot.

"By the way, I wonder who you are?"

Lin Changqing started chatting with the middle-aged man in front of him, but he didn't know his name, which was a bit rude.

"Security Section Chief Liu An, I won't waste any more words. I want to ask if you know how to display the contents of the note?"

"I know!" Lin Changqing answered immediately, "But I don't know if it's the method I know."

"Hurry up and tell me!" Liu An suddenly became excited.

"How should I put it? Do you know chemical reagents? If you do, it's easy to understand. If not, it's a little difficult to explain."

Chemistry has all kinds of symbols and names, which is really hard to explain.

"What chemical reagent? What is that?" Liu An looked confused!
