Although before Xinggan and Jianyuan, simple and primitive telegrams had begun to be used and played an extremely important role. It is also because of this. In the past twenty years, the Ming Dynasty has established a telegram network covering all provinces across the country and connecting the Xia people of Nanyang.

The emergence of the Telegram Network fundamentally changed the Ming Dynasty's grasp of information. However, on the battlefield, the most widely used pigeons are still the carrier pigeons. These specially trained communication pigeons are extremely widely used on the battlefield.

Unlike the army with radio stations hundreds of years later, communication in this era was extremely reason. If the troops in the front wanted to contact the troops in the rear, they had to use the pigeons carried with the army to transmit intelligence. Facts have proved that trained pigeons can fly about 60 miles, which is enough to deliver a note with commands. Some excellent pigeons can fly farther and be used for long-distance transmission of information. However, in the Ming Dynasty, these long-distance pigeons were replaced by telegrams, and pigeons are often only suitable for short-distance communication on the battlefield.

During the war, the notes carried by specially trained carrier pigeons often became life-saving straws for many troops, and played an extremely important and even irreplaceable role on the battlefield. Especially for small-scale troops on the front line, carrier pigeons are often the most effective communication tool for them to get in touch with the back defense. Almost every small team of the Ming army carried carrier pigeons to maintain contact with the large troops in the rear. As the enemy, the Qing Dynasty also learned to use carrier pigeons over the past years, and also used these inconspicuous pigeons on the battlefield on a large scale to convey intelligence and commands.

When Jingnan was in the siege, both sides seemed to be extremely dependent on the pigeons. The defender relied on contacting the outside world, and the siege needed the pigeons to convey messages. Because of this, both sides chose to ignore the pigeons flying in the air, and seemed to have chosen to give up. However, sometimes, they still hunted to obtain information on the pigeons. However, after several attempts, both sides chose to give up.

Almost while putting the pigeons on the battlefield, the Ming army formulated communication passwords to convey intelligence. After suffering many years of losses, the Qing army also learned to use passwords. Most of the time, even the pigeons that shot the other party could not be able to crack the other party's password.

However, even so, both sides will still send the best musketeers to shoot the pigeons flying through the air to obtain intelligence. Almost every day, at least a few pigeons, and at most dozen pigeons are killed. The intelligence carried by the pigeons will eventually appear on the desks of intelligence personnel on both sides. However, most of the time, these broad-minded intelligence is often a piece of waste paper. After all, without deciphering the password, intelligence is just a piece of waste paper.

"It's coming again!"

Once again, Li Qingyun said helplessly. At the same time, he put the information he had just obtained on the table.

"What is certain is that Jiannu used a new password!"

As Jun Zhengsi's password cracker, for him, deciphering the password is his job, and in school, he learned this, and cracking Jiannu's password is also an extremely easy thing. The reason why it is easy is not because Jiannu's password is not complicated. The Heavenly Stems and Earthly Branches and numbers seem extremely complicated. But in fact, Jun Zhengsi has always mastered their passwords - no matter how complex the password is, it cannot withstand someone's leaks. Even with Jiannu's backup password, Jun Zhengsi also has a copy. The "chess pieces" that penetrate it will naturally take out the password and hand it over to Jun Zhengsi.

Therefore, the orders carried by the Qing army on the battlefield were not a secret. Many times, it was because of the Qing Dynasty that the Ming army could firmly grasp the initiative on the battlefield. But now this information is different from the past. His password is completely different from the past.

"Cracked?"

Gao Shiqi asked back. Although he knew that one day the Qing Dynasty would definitely use the new password, he did not expect that the other party would react so quickly.

Of course, what was even more unexpected was that the infiltration of the inside line inside the Qing Dynasty did not transmit the relevant information, which was what he couldn't understand the most. After all, according to past experience, he would get a new password as soon as possible, but this time there was no information on the Qing Dynasty to change the password.

What exactly happened?

What caused such a change now?

"No, but it's certain that they have enabled the new password. If I'm not mistaken, there must be extremely important information in these pieces of information."

Any enemy will take the initiative to learn, and Jiannu is no exception. They learn to use pigeons widely on the battlefield of the Ming Dynasty and learn to send messages from the Ming Dynasty. They also learned to prevent risks from the Ming Dynasty. The so-called risk prevention is to formulate special special passwords for a certain task, and it may even be known to only a few people.

"Is there a way to crack it?"

When Gao Shiqi heard this, he immediately became interested. Although he knew it was very difficult, sometimes some miracles would happen. After all, the facts were impermanent and nothing was absolutely absolute.

"It's very difficult. It seems that they use the heavenly stems and earthly branches to add numbers. From the word group, they should have corresponding codebooks, which may be one or several books as decode books. I think this information may have used three books as decode books. Not to mention the pages, the word speculation is, but these three books, it's not clear which book these three books are, everything is useless, and its organizational rules are different from the past. At least in the short term, they can't decipher it at all..."

Li Qingyun's answer made Gao Shiqi silent. He did not urge his subordinates to strictly order him to decipher, but chose to accept this reality. Anyone who works in intelligence knows that deciphering passwords is not something that can be promoted by force, but also by luck.

"It seems that they must be planning a big deal!"

Staring at the inexplicable information, Gao Shiqi sighed.

"It must be, otherwise, they wouldn't use such complicated passwords, and they have never appeared in the past. It's certain that there are no more than ten people who know this set of passwords in the Qing Dynasty, and it may even be even less..."

After a brief pause, Li Qingyun looked at Gao Shiqi and said.

"Can it be the chief of Jiannu? I have heard that the man is very interested in passwords and has also compiled his own password..."

"It's indeed possible, after all..."

Gao Shiqi smiled, with some helplessness in his smile.

"They compiled the passwords and learned from us, and even their person in charge was from Qinghe Academy, so what? If it comes from their hands, this password will definitely be passed to us."

During the Qing Dynasty, when the Qing Dynasty sent young people to the Ming Dynasty to infiltrate the academy, many people were also turned against the "chess pieces" of Jun Zhengshi. Those "chess pieces" have always played an extremely important role. Gao Shiqi is not unfamiliar with this. Before he came to the front line, he had already learned about this information from Jun Zhengshi.

It is also because of this that in some cases, they will tolerate the infiltration of the Qing Dynasty on the Ming Dynasty. It seems that it is not good for the Ming Dynasty, but in fact, this infiltration is more beneficial to the Ming Dynasty. It is through those people that the Jun Zhengsi completed the high infiltration of the Qing Dynasty.

"If it was speculation before, then now..."

He clicked his finger on the note, and then Gao Shiqi said with a serious expression.

"Now, it's basically certain that Jiannu still hasn't given up. They are planning a big event! Okay, if you can decipher, you can decipher. If you can't..."

The password will only suddenly change when planning a big event. Otherwise, there is no need for them to do this at all. But what kind of big event will it be?

On the battlefield, the most difficult thing to see through is the fog on the battlefield, and the task of the intelligence personnel is to help the commander see through the fog. But in many cases, how many people can see through all this?

Shaking his head, Gao Shi sighed.

"You can't force this kind of thing, right?"

Soon, Gao Shiqi came to Li Dingguo. As the chief and deputy of the army, his mission was to provide information support to Li Dingguo. After the siege of Jingnan, he directly controlled the contact with the "chess pieces" in the city. When he sent out the information he had one by one, Li Dingguo said with a serious expression.

"You mean, the hidden thread in the city, think Jiannu is making plans to break the current siege?"

As the commander of the Western Expedition Army, Li Dingguo, who had personally formulated the entire siege plan, was very confident in his own allocation. He did not think that he had any loopholes that could allow the Qing army to get into.

"Well, it's not that simple for them to break the siege. Although they were just surrounded by trenches, there were fortresses between the trenches. It was basically a dream that the Qing army wanted to rescue the siege. It was simple for us to attack the city, but Jiannu was not us. They had no siege cannons, so they could only use people to pile up and chew. Before they could chew them, they would probably have to pay a lot of money."

Shaking his head, Li Dingguo said confidently. As the commander, he has fought for many years, and he still has this confidence.

"They want to save the situation, there is no possibility at all."

When he said this, his tone was full of ridicule.

"But the king, based on the information currently available, they do have plans in this regard!"

Gao Shiqi hurriedly reminded him.

"It's okay, if they want to go out of the city to counterattack, it is also a good thing for us. To be honest, after so long, the brothers are tired of it. They can take the initiative to attack, and we just stand in the trenches to shoot the target. In this way, the brothers can have something to do, which is a good thing for us..."

Good thing...

Gao Shiqi is not as confident as Li Dingguo. As the chief intelligence officer, he always considers the problem from the worst perspective, so he asked again.

"But... King, what if they conquer our army's defense line?"

Considering Li Dingguo's face, Gao Shiqi quickly added.

"Of course, here is just an assumption. Even if there is one in ten thousand chance, it should be considered. Of course, here is to know that the king's deployment must be foolproof!"

Even when he opposes, he does not forget to compliment the other party. This is one of the reasons why Gao Shiqi is young and can become the chief and deputy of the Western Expedition Army, and of course it is not the main reason.

"You doubt this coach!"

Staring at Gao Shiqi, Li Dingguo said coldly.

"Do you question my coach's deployment?"

His voice changed and Gao Shiqi hurriedly said.

"I dare not, I just... the responsibility is! That's why I boldly assume..."

When he said this, Gao Shiqi felt a cold sweat broke out from behind. Jun Zheng... For the main general, it has never been a good role. On the one hand, they maintain military discipline and preside over military law, and at the same time play the role of military supervisor. Jun Zheng, from ancient times to the present, has never liked that general, but Jun Zheng has not had any conflicts with the main general until now, and both sides carefully maintain the border - combat command.

Of course, Gao Shiqi knew very well about this border. He would not touch it, but he knew very well that the person in front of him was not an ordinary commander, but a king of the Ming Dynasty, who was deeply trusted by His Majesty the Emperor. If there was a conflict between the two sides, before His Majesty could speak, Jun Zhengsi would probably transfer him back first.

"Bold assumptions, bold assumptions..."

Repeating these four words, Li Dingguo looked at Gao Shiqi seriously and then asked back.

"Gao Shiqi, many people say that you are a smart person, but why did you confront me at this time? Are you not afraid of me? Do you believe it or not? As long as I express my dissatisfaction, Jun Zhengshi will at least transfer you back! If I am as expected, even if I am not allowed to sit on the bench, I will transfer you to the place where the bird will not shit. Don't say anything about Jun Zheng's bones! No matter how hard the bones are, they will not be harder than the hammer!"

Junzheng's bones have been proven countless times over the past years, and this is also Junzheng's pride. In many cases, they are proud of it and try every means to safeguard Junzheng's bones.

"What the king said is good, but his servants say slightly, but their responsibilities are!"

Gao Shiqi, who seemed very nervous, calmed down when he heard this sentence and no longer worried about gains and losses like before.

Junzheng's bones!

This is exactly the pride of all Junzheng. He raised his head, faced Li Dingguo's gaze, and said in an extremely firm tone.

"The responsibility lies. Some things must be done, even if it is offending the king, it will be spared! Otherwise, I will be ashamed of being the military commander. If I cannot uphold my duties in the future, the military power will be damaged. Even if my crime is to be punished by my crime, I will be redeemable if I die a hundred times!"

"Okay, okay, you can't redeem it if you die!"

Staring at Gao Shiqi, Li Dingguo, who seemed to be serious, suddenly laughed.
Chapter completed!
