Siheyuan: Returning from studying abroad, with extraordinary understanding

Hearing Liu An ask this, Lin Changqing knew that he had some concerns.

I still haven't gained trust.

However, it is right to have concerns. If he were in his shoes, he would not dare to use the reagent rashly.

"Chief Liu, what I say may not be convincing."

"These reagents all have a characteristic. When they are dropped onto ordinary white paper, they will not leave any color. Only when there is a corresponding reagent on the paper will the color change. Look!"

Lin Changqing tore off a small piece of paper, soaked it in the reagent, then took it out and showed it to them.

Liu Anding looked at the note in Lin Changqing's hand and found that it did not change color.

"Amazing! Chemistry is so magical!"

Liu An was amazed. With Lin Changqing's demonstration, he believed it for the most part.

Combined with his previous judgment, he no longer hesitated and took out the note immediately.

“Just put it in and soak it?”

"Yes! Take out the paper when it's soaked."

Lin Changqing did not ask for the note. This step was very simple and he did not want to interfere.

When Liu An was about to put the note in, Lin Changqing subconsciously turned around and didn't read the contents.

The soldier who had been staring at Lin Changqing glanced at him inconspicuously.

Lin Changqing was quite sensible, otherwise he would have reminded him.

Now, Lin Changqing is still a suspect and the soldiers don't trust him at all.

Liu An also noticed Lin Changqing's actions and thought highly of him.

After soaking, Liu An took out the note and the words on it began to appear.

【Preparation completed, proceed as planned! 】

A sentence without a beginning or an end, it's really confusing!

"This? How could this happen? There is no information at all!"

Liu An cursed in his heart.

With just this one sentence, Liu An could not see any useful clues.

I didn’t know what to do for a moment.

Lin Changqing, with his back to him, waited for a long time but did not hear Liu An speak.

Have you never thought about it?

It shouldn’t be like this. It has no effect. I should have asked myself this question a long time ago.

Lin Changqing didn't think about it any more, and without turning around, he asked:

"Chief Liu, what's the result?"

"Not very good, turn around and take a look!"

The content of the note was not a secret, so Liu An let Lin Changqing read it.

"Ah? Can I see it?"

Lin Changqing still needs to confirm it.

"Yeah, sure! It's not a secret."

After getting the affirmation, Lin Changqing turned around.

The reason he did this was because he was still traumatized by the incident.

When I was standing in line, I took a quick glance and simply read the note, then I was held down by several people.

He was afraid that he might see some secrets and cause a lot of trouble.

Especially after he returned to Sijiu City.

He is not a regular staff member. What should he do if the enemy spies find out and try to recruit him?

He is not a leader, so there will be someone to protect him and his family at all times.

Seeing the contents of the note, Lin Changqing felt relieved at once.

There is nothing confidential and there is no need to be afraid.

However, when Lin Changqing saw that Liu An and the soldiers were all confused, a strange feeling flashed through his mind.

The atmosphere became strange at this time, and the three of them looked at each other.

"Cough!" Lin Changqing couldn't stand it anymore and broke the silence with a cough:

"Chief Liu, why don't you investigate and arrest them?"

"Arrest someone? Arrest who? Comrade Lin Changqing, what have you figured out?"

When asked this by Lin Changqing, Liu An knew that Lin Changqing must have seen something.

His mind kept thinking about the contents of the note. What had he prepared? What was the plan?

"Can't you see?"

"Nonsense, if we had known, we would have arrested him long ago."

Hearing Lin Changqing asking him this, he patted his shoulder and said unhappily, "Tell me quickly, what did you see!"

"Okay, then I'll tell you what information I know."

Seeing that Liu An was getting anxious, Lin Changqing stopped talking nonsense.

"The information is all on the outside of the paper. First, judging from the whole incident, the man must have been dressed very similarly to me, with a height and age similar to mine. He was also not wearing a tie, which would have made the person who delivered the note mistaken for me. Based on these characteristics, the scope of the investigation is much smaller."

"Second, we need to find out if there are any passenger ships that are docked at the same time as the one I'm on. If not, then he is on the same ship as me. The scope is even smaller. The passenger list should be easy for you to obtain."

"Third, making special reagents requires a basic knowledge of chemistry. The people who go online may be teachers, doctors, college students, etc. The occupation of the person who receives the reagents is uncertain. You have seen the process of making reagents. It is too simple and you can learn it with simple training."

"Fourth, making special reagents requires things that can only be done in the laboratory. This scope is even smaller. There shouldn't be many people who can go in and out of the laboratory."

"So there is this information!" Liu An suddenly realized, "I have been wondering what they are up to, and I was deceived. Comrade Changqing, thank you."

He had experience in underground work behind enemy lines, and when Lin Changqing reminded him of this, he suddenly thought of many situations and possibilities.

"Chief, you're welcome. You just paid too much attention to the contents on the paper. Even without my reminder, you would have thought of it soon."

Lin Changqing said.

The four pieces of information he just mentioned excluded him. Liu An didn't expect that it was because Lin Changqing had not been cleared of suspicion.

"I will immediately arrange for someone to search. I don't believe that we can't catch them."

Having said that, Liu An was about to leave.

"Wait, Chief, when you arrested me, you might have alerted the enemy. So much time has passed, they might have already left Tianjin Port."

Lin Changqing called Liu An and told him what he had thought.

"Why didn't you say so earlier? What's the point of your analysis just now?" The soldier next to him suddenly became impatient. "Are you deliberately stalling for time to let them escape?"

Lin Changqing has been cleared of suspicion, but in his eyes, Lin Changqing is still an enemy spy, so his attitude will naturally not be good.

Hearing this, Liu An was also stunned. Yes, Lin Changqing has not yet been confirmed to be innocent.

He couldn't help but glance at Lin Changqing.

However, Liu An did not speak. He wanted to hear how Lin Changqing explained.

Lin Changqing's expression remained unchanged, he remained calm and said:

"The information I mentioned is still useful. For example, even if the person who made the special reagent is not a real enemy spy, he has been in contact with enemy spies. In this regard, you can check and there will be some useful information."

"Even so, the information you provided is half true and half false, and you are highly suspected of being an enemy spy." The soldier still didn't believe it.

"I'm not an enemy spy. All the information is analyzed. Of course, some is true and some is false." Lin Changqing spread his hands.

"You!" The soldier didn't know what to say for a moment.

He was very dissatisfied and stared at Lin Changqing.
