His mind was already a little groggy from his thoughts, so Yu Jingque decided not to think about it anymore.
get off work.
But when I got off work, I met Kenji Hashimoto.
Since they met, Yu Jingque naturally said hello and asked by the way: "Teacher Hashimoto, is it easy to decipher the military commander's documents?"
"It's not easy." If Kenji Hashimoto says it, no decryption is easy.
As long as it is encrypted by the enemy, it will be difficult for you to decrypt it.
Of course, some people are lucky and may successfully decrypt quickly, but if they are unlucky, it will be difficult to decrypt.
However, Yu Jingque also took a class from Hashimoto Kenji. If it is digital encryption, it is indeed difficult.
But this file is not.
This document is a letter, to put it bluntly, it is the letter inside the letter.
Since it is a letter, it is naturally a long paragraph.
You can't write a lot of numbers in the letter, otherwise even a fool can see that there is something wrong with the letter.
Since it is text, the encryption method is a rule, which is much simpler than digital encryption.
When Hashimoto Kenji said it was difficult, Yu Jingque wondered if he was being modest.
"Teacher Hashimoto, you are too humble." Yu Jingque said.
Kenji Hashimoto said seriously: "I'm really not humble. When I got the document before, I thought it was easy, but after trying to decipher it, I found it was not easy."
"The rules should be irregular and contain a lot of content, so it is not easy to decipher them."
Hearing what Kenji Hashimoto said, Yu Jingque said, "Thank you for your hard work, Mr. Hashimoto."
It's best to never successfully decrypt it.
Hashimoto Kenji's work attitude is like this. If it were He Siliang, he would not get off work now. He would definitely be working hard in the Secret Service Section and must decrypt it.
But Hashimoto Kenji is different. He will get off work when it is time to get off work, and may go back home to decipher.
After sending Kenji Hashimoto away, Yu Jingque wanted to meet Han Chen.
Han Chen has not been notified of what the Secret Service discovered today. Yu Jingque was worried that the Secret Service would really find something at the post office.
Even this document is not as unimportant as Yu Jingque and Cai Wangjin guessed, but is actually very important?
This problem needs to be solved urgently, so Yu Jingque and Han Chen need to meet.
At the police station, I took the opportunity to take a look at Han Chen, and then Yu Jingque left.
After arriving at the old place, Han Chen came over after waiting for a while.
"What's wrong?" Han Chen asked.
The more urgent the moment, the less likely it is to meet casually. Han Chen believed that his meeting with Yu Jingque should be avoided if possible.
In fact, before this incident, Yu Jingque and Han Chen had not seen each other for a long time.
"I found an envelope and a document..." Yu Jingque finished the matter quickly without any nonsense.
In fact, he knew that Han Chen was very busy, and Han Chen had to take charge of this matter.
After hearing the new news about Yu Jingque, Han Chen said: "Cai Wangjin, this old fox."
"Is there still a problem with the post office?" Yu Jingque asked.
"There are still a few letters being sent, I will ask someone to find a way to get them out," Han Chen said.
This method has been used by the military commanders all the time. They are not afraid of investigation by the Secret Service Section and the Japanese.
Because there are too many letters, you can check when to go.
But things are different now. Now that Cai Wangjin has mastered handwriting, it will be troublesome.
But there is also an advantage. Cai Wangjin focuses on those with the same handwriting, so Han Chen can ask the military commander to deliberately write something to confuse Cai Wangjin.
At the same time, change a group of people to write letters, so that the message can continue to be delivered.
In Han Chen's mind, he immediately thought of a way to deal with it.
The only premise is that the current letter needs to be retrieved.
Because these letters are not fake, but real. It is a shame to use them to confuse the public.
Yu Jingque asked: "Can you take it out?"
"It should be possible. After all, Cai Wangjin just got the envelope and asked the people at the post office to compare the handwriting. It's a lot of work and it's hard to be foolproof." Han Chen was not very worried about this.
Hearing Han Chen's words, Yu Jingque breathed a sigh of relief.
Then he asked: "What is that file?"
"I don't know either. I'll go back and ask." Han Chen didn't know the content of the document either.
Han Chen is not responsible for how the sent messages are encrypted.
So now even if Yu Jingque told Han Chen the contents of the document verbatim, Han Chen would not be able to distinguish it.
But Han Chen can still get the answer as long as he remembers a paragraph and goes back to ask.
But when he got the answer, he would not tell Yu Jingque because there was no need to tell Yu Jingque.
Han Chen only needs to know that the document is in Cai Wangjin's hands, and if it is important, he should handle it carefully.
If it's not important, ignore it.
There is no point in telling Yu Jingque. There is no trust or distrust, but there is no need to bother.
But Yu Jingque wanted to know.
what to do?
Yu Jingque had no intention of asking Han Chen. Yu Jingque wanted to go back and ask Ji Youning. Han Chen didn't know, but Ji Youning didn't necessarily know.
"Do you have any news here?" Han Chen asked.
"There is no news. Cai Wangjin's source of information is very confidential. I don't dare to inquire or show interest." Yu Jingque shook his head in embarrassment.
Because the source of the information was very sensitive to Cai Wangjin, Yu Jingque could not even mention it.
"Where are you here?" Yu Jingque turned to ask Han Chen.
Han Chen was even more confused. He had investigated within the military command and no one knew about it.
Han Chen said: "I guess now that the people involved in this matter are either dead or arrested."
"It shouldn't be possible to get caught. The four of us are very religious." Yu Jingque said.
These four people could not be acting, because Yu Jingque was watching from the side during the torture. It was real torture, not fake at all.
If someone inside has a problem and Cai Wangjin tortures him like this, how can this person endure it?
If you can endure it like this, how can there be any problems?
Then the person who has the problem will be among the dead.
But Yu Jingque thought it was impossible. If this person had a problem and knew that the Secret Service Division was calling today, how could he stay here and exchange fire with the Secret Service Division people?
Han Chen explained: "The problem with this is not that they betrayed the organization, but that the information from the liaison station was leaked from them, and they may not even know it."
Hearing what Han Chen said, Yu Jingque had to say that the people in the army were quite capable.
In such a short period of time, a possible way was found.
The news was leaked from the people at the liaison station, but the people at the liaison station didn't know about it, which led to the current result.
But how could the news leak out without knowing it, and how could it end up in the hands of Cai Wangjin after it was leaked?
Still can't understand this?
Han Chen said: "Be careful yourself. If you can't find out, don't ask. Be careful about exposing yourself."
Yu Jingque's identity is very important, and the liaison station is already done. If Yu Jingque is exposed because of this incident, he will lose his wife and lose his troops.
So Han Chen asked Yu Jingque to protect himself first, and he would investigate this matter himself.
"If I get the chance and get the news, I will inform you again." Yu Jingque said what needed to be said, indicating that he understood what Han Chen meant and that he would not take any risks.
Because the contact station has indeed been destroyed, it would be meaningless if he was exposed again.
