He then picked up the second intercepted secret message numbered 6089- 11. This was sent by the mysterious radio station. At present, the battle of Xuzhou was in a stalemate, and this radio station was unusually active. It played a role in turning the tide at critical times and making the commander make up his mind.
However, he had already deciphered this radio station, so the contents of the secret message were like plain text to him: "The enemy intends to use a portion of their forces to pin down the other party from the front, while the main force detours to the west.”
This was obviously a strategic decision from the Japanese Army's General Staff Headquarters, attempting to stage another big detour and encirclement. At present, the main force of the national army was continuously entering the Xuzhou area, and the development of the Xuzhou Battle was not optimistic.
He couldn't help but admire the value of this comrade's information. It was not inferior to the information he had sent out about the Golden Mountain Guards 'roundabout landing.
Ever since the Japanese army's General Staff moved to Nanjing, the information that he obtained from them was much less useful for the current battle.
Compared to the channel through which the mysterious radio station obtained information, the password of the radio station was set to a lower level. He had once arranged for Zhou Hui to send a secret message to the other party, warning them to raise the password level according to the frequency of the mysterious radio station. However, there was no change. The following secret messages still used the old password. The mysterious radio station seemed to be a one-way communication. It only sent messages and did not receive telegrams.
He had to keep this radio station hidden. The only way to hide it was to include it in his deciphering range so that the deciphering team would not be able to get their hands on it. Otherwise, with the current level of the cracking team, it would only take a month to crack this set of codes. Therefore, he had to make some achievements in cracking the code to have a reason to continue protecting this set of codes and transfer more codes to the Intelligence Group.
He even wanted to protect this radio station even if he had to sacrifice his team. This was the most important source of intelligence for the national army, and it concerned the lives of hundreds of thousands of soldiers.
Other than that, there was another way to find this mysterious radio station and inform the other party.
However, how could he find the other party?
His identity was actually very awkward. He couldn't be too active in everything, and he had to crack some valuable codes to maintain his status. It was a pity that Uncle Ho had left. Otherwise, he would have sent a message to the higher-ups to provide a few more valuable radio station passwords.
Oh right, there's a way, Wang Xing! Wang Xing would definitely have some radio codes. It was time to teach this old fox a lesson.
What was Wang Xing's true purpose for defecting? How should he get along with her?
For the past three years, Wang Xing had always been in the light while he had always been in the dark. He had seen Wang Xing very clearly and had analyzed this person himself. He had joined the revolution in the early days and had experienced life and death. Moreover, he had deep feelings for his parents, wife, and children in the countryside. Although he was greedy and lecherous, he should still know how to make a choice when it came to national justice.
The Japanese would not understand the Chinese. On this land, the inheritance of Chinese civilization had never been wiped out. The land could be conquered, but the things in the bones of the Chinese would not be conquered.
Wang Xing could fool Yuta Matsuta and Shunji Kumamoto, but he couldn't get past him.
------
Thinking of this, he picked up the third secret message, serial number 7000. This was a new radio station. The message only had five words, so he casually put it aside.
Due to the lack of telegrams and the fact that the Chinese liked to use ancient characters, there was no pattern to follow, so it was very difficult to decipher.
Ancient poetry?
He suddenly remembered a file that the Japanese Military Police had transferred to the Special Higher Police a week ago. There was an underground gang member who was arrested and tortured but did not speak. In the end, he was escorted to the execution ground and shot. In order to warn the others, some onlookers and reporters were arranged. Before the underground party was executed, he did not shout any slogans. Instead, he looked up at the sky and sighed." A thousand years of white clouds in the sky ", and then he died heroically. He still remembered that this file was 0051.
Later on, this file was brought up by Kumamoto Shunji because of the ancient poem that the commoner wrote before he left.
'A thousand years of white clouds in the sky' was an ancient poem from the Yellow Crane Tower. It was written by the Tang Dynasty poet Cui Hao.
Once upon a time, people had gone by yellow crane, and there was only Yellow Crane Tower left here.
The yellow crane never returned, and the white clouds were empty for a thousand years.
Qingchuan is full of Hanyang trees, and the grass is lush on Parrot Island.
Where is the village at dusk? the misty waves on the river make one sad.
At that time, Kumamoto Jun was puzzled, so he handed the file to him and asked him to crack the secret.
------
He had come into contact with a few underground party's telegrams. The underground party's secret telegrams were divided into two categories. One was a low-level single-table replacement password, which only changed the order of the four-corner number dictionary and added a number. He had encountered this kind of password a few times and cracked it immediately. Through the contents of the message, they found out that the other party was just an underground organization and did not have any core secrets. They pretended to spend a few days to crack the radio station.
The other was a high-level password that he could not crack. There were many repeated codes in it. This was a type of compound password. This type of password was the most difficult to crack because there was no pattern to it. Every word in it would have a different code, and the same code would represent different words. There must have been a set of random numbers added to it. This kind of encryption could use pi, or it could be a random article.
He tried to use the words in this ancient poem to correspond to the four-corner number, which was the universal code. The four-corner numbering system was created by Mr. Wang Yunwu, who was working in the Commercial Press at that time, in 1928. Later, the clear text of the Chinese Dynasty began to use the four-corner numbering system.
The rules of the four-corner number: one horizontal, two vertical, and three dots. A cross with four inserted into five and a square with six, and a seven-point eight-eight was nine. This way, each Chinese character could be represented by a four-digit code.
Inspired by the four-corner number, the various forces of the Celestial Empire created their own secret codes. It was just that the order was changed. This kind of code book was called the 'Single Table Substitute Password'.
------
The code of the underground gang might be related to the ancient poem. He followed the four-corner number of each word in the ancient poem and added and deducted the secret message. According to his experience, he still could not decipher the secret message.
Yes, no matter how stupid the underground party was, they wouldn't directly tell the enemy the key. There must be other secrets inside.
There was a basic principle for the secret message, which was that the code must be simple and reliable to ensure that the message was sent and received accurately and timely. Otherwise, if the secret message was too complicated, it would bring great difficulty to deciphering the secret message. It would be really tragic if he could not even decipher it himself!
Suddenly, he thought of another ancient poem,'Moonlit Night on the Spring River'. There was a line in it that said,' The white clouds go away leisurely.'The title of this ancient poem was five words.
Spring River Flower Moonlit Night was an ancient poem by the Tang Dynasty poet Zhang Ruoxu. The entire poem had 252 words, and it could be compiled into a long text.
Therefore, he directly brought this ancient poem into plain code and tried to add and subtract it with the intercepted message.
The first time, add, add, add. The second time, reduce, reduce, reduce. The third time, add, add, add. The fourth time, add, add, reduce, reduce. The fifth time, reduce, add, add.
Fortunately, the message wasn't long. When he tried 'add, subtract, subtract' for the ninth time, the cold five-word message finally had practical meaning. Moonlit Spring River!
It was a secret communication message with no intelligence value. The secret code has been received!
This was a message to inform the headquarters that they were safe and that the 'Moonlit Night on the Spring River' was the key! The underground party that was arrested should be a liaison who handed the key to an underground organization in Shanghai. There was no need to bring any passcode book.
After being arrested, he weighed his options and used that poem to send a message. It was estimated that the underground organization had obtained the information, but it took a week to understand the actual intention of the liaison and translate the message from the headquarters.
He had heard that the underground party's advanced password was very powerful and had never been broken by the Special Higher Police or other organizations. Could this be the underground party's advanced password?
The spiritual altar was ethereal. This was the most rare inspiration in deciphering codes. Some people often lamented coincidence and luck, but little did they know that the mystery behind every coincidence and luck was an attempt to maximize the probability!
Cracking codes, swallowing geniuses into a black hole, but there would always be people who saw the light behind the black hole!
Cracking the password was easy, but it was really difficult!
This also indicated that every piece of information that the Shanghai underground party would pass on in the future would be clear in front of Cheng Xiaofeng.
------
After deciphering the secret message, Cheng Xiaofeng's excitement only lasted for a second. What followed next was an additional burden.
He did not know much about the underground party, but he was loyal to the National Party. He did not think highly of the underground party, nor did he hate them. As long as it was a war of resistance, he could give the underground party some protection at the right time!
However, in the future, if the military organization wanted to deal with the underground, they would have this set of passwords and the encryption method hidden behind them. It would be an effective weapon.
He gathered his thoughts. The most important thing now was to arrange for Feng Yuan, Zhou Hui, and the others to evacuate Shanghai.
Therefore, he had to make a trip to the concession to confirm their safety before ordering them to head to Changde, Hunan! The higher-ups would arrange for them to go there.
In fact, he was very reluctant to let the two of them leave. They were good at action, so it was a pity to leave like this. There was nothing they could do about it, but their departure was also a good thing. If they left, the team's ability to move would be greatly reduced. The higher-ups would not let their team participate in assassinations anymore to reduce the risk of the team being exposed.
However, the key question was, could they return home safely and smoothly?
He put the documents in the drawer, stood up and stretched. Seeing that it was about time, he picked up the stack of phone records and walked out.
Kumamoto Shunji looked at the dozen suspicious phone records that Cheng Xiaofeng had sorted out. His eyes were filled with bitterness. There was no result he wanted at all.
He looked up at his students and saw the same helplessness.
"Xiaofeng, it seems like we still have to go to that safe house. Arrange for someone to go to the military police and bring the landlord to the safe house.”
"Alright, Teacher! Should I wait for Captain Suzuki to return? Now, everyone was out! Besides, I don't know where it is." Hearing this, Cheng Xiaofeng's heart tightened, but his face remained calm.
"Near Zhengyuan Street, there are three apartments that are more obvious. We have people guarding there.”
"Alright, Teacher. I'll arrange for a car.”
"Forget it, the vehicles have been sent out. The military police command has already ordered that before the killer is caught, the cars are not allowed to go on the road.”
"Alright, teacher. We need to change into casual clothes. Otherwise, it will damage the reputation of the Empire's soldiers.”Since he couldn't stop it, he would try his best to delay it.
At this moment, the phone on the table rang.
When Kumamoto Shunji picked up the phone, Ichiro Suzuki's excited voice came through the phone. Even Cheng Xiaofeng could hear it clearly." Leader, good news!"
Cheng Xiaofeng's heart sank. Could it be that Feng Yuan and the others had been captured?
"Tell me, what good news!"
"We've found the gun. It's in the warehouse at North Station!”
"Alright, let's go to the safe house. You take that gun to the safe house.”
"Ha Yi!"
