Lord, the reinforcements have already gone to Mengyang City, please be sure to win this battle.

Ah Zheng muttered in his mind as he walked quickly to the long table in the lounge and picked up the latest work of the Creation Institute, "Regulation No. 2", a wooden shell with a special ink stone pen embedded in it.

It is said that the ink stone embedded in this pen, called "pencil", was not owned by nature, but was also made by the Creation Institute, and the mystery was taught by the military master.

This skill of making a special ink stone that can be used to write certainly makes everyone more in awe of the military master, but it is more about the convenience of writing.

Ah Zheng first used stones to write in the dirt when he first studied at the Xuanjing Academy, but then he tried the brush with great difficulty, and it was not until he used this "pencil" for the first time that he was first struck by the ease of writing.

This "pencil" is so convenient to use compared to a brush that it is not only easy to use, but also can be written for a long, long time by shaving off the wooden shell of the refill to reveal a new unused ink stone.

However, what made Ah Zheng feel quite a pity was that out of secrecy, like many other utensils, the military lord also set rules for the use of pencils, and pencils could be used for internal letter transmission, but once it was to communicate with other people outside the castle, it was strictly forbidden to use pencils.

The number of pencils is also strictly controlled, and only after passing the cultural assessment of the Elite Academy and becoming a full member of various institutions can he have the opportunity to use pencils, if he is not a key intelligence agency such as the Secret Academy, with his lower rank, he would not be qualified to use pencils.

"Returning to Mengyang City and Mang Ancient Castle, the Chinese army camp in the Mansi Village has sent reinforcements, with an estimated cavalry of 2,000 to 3,000, an error of 1,000, an estimated infantry of 15,000, an error of 1,000, and a time record: June 21; Recorded by: Meng Zheng, the leading point of the Mansi Village in the Observation Hall of the Secret Academy; Supervisor: Meng Yu. Ah Zheng quickly wrote down the information on the paper, and without thinking, attached his and Ah Yu's names.

By attaching a name, you will be held responsible, but sometimes this practice is also a way to get away with it.

Of course, taking the risk of sending inaccurate information like his is a huge risk in itself, and once the information is proved to be correct, the other people at the point of contact will be exempt from the crime of not being liable if something bad happens because of the timely delivery of the information; If the information is wrong, no one else will be held liable because they are not directly related to the information.

In general, Ah Zheng's approach is to pay his own price to help others in the contact point almost free of charge. This concept of commitment has been established in the hearts of the members of the Academy through various rules of the Academy, and finally a qualified member of the Academy of Secrets like Ah Zheng has been cultivated, which is also what Jiang Yu needs.

After writing the information, Ah Zheng quickly completed the packaging of the information in accordance with the rules of the Secret Academy, made fire wax on the seal, and made a special intelligence mark at the interface.

In the intelligence envelope, according to the rules of the secret academy for information transmission, several erroneous information were mixed in it, and the real correct information was hidden in the middle of the paper of the wrong information. This is a secrecy method devised by Jiang Yugang, because the use of ciphertext is too complicated for the current cultural level of intelligence personnel, and it is easy to cause distortion in the transmission of intelligence, which will outweigh the losses.

Therefore, the method he adopted was to hide the correct information in the wrong information, and designed several corresponding hiding methods, each of which has a corresponding method, and the method of finding the correct information from the wrong information.

And there is a message attached to the envelope, this information is used to prompt the concealment method used in this envelope, and the members of the Secret Academy who receive the envelope will naturally go to the envelope to find the correct way to hide the letter, so as to find the real information.

And people other than the members of the Secret Academy, those who do not know how information is transmitted, naturally do not know about this arrangement, and cannot find the correct information from it.

This method is of course insecure, because if someone can get hints from the members of the Secret Academy about how all the letters are hidden and how they are concealed, then it will be easy to find out the correct information.

On the one hand, due to the current technological and social environment of the mid-fifteenth century, there is not enough ability to exchange information, and the intelligence members of each force are already limited, so it is even more difficult to find out the internal information of the secret academy, the internal intelligence department of Manggu Castle.

In particular, there are many secrets within the Secret Academy, and all kinds of secret arrangements are interlocking, unless you know all the secret arrangements and secret rules, it is difficult to peek into the secret information inside the Secret Academy, and you will not be able to know any important information just by simply knowing a little secret in the Secret Academy.

On the other hand, there are also many restrictions on personnel within the Secret Academy, such as restricting the communication between different departments, and even the same department, there are also restrictions on the communication between different branches, and the information held by different members of the Secret Academy is very different.

Knowing one-sided information is not enough to give a person a full picture of it, so that even if a member of the Secret Academy betrayed, the information that was actually leaked because of his betrayal is very limited. For example, the way the Watchman Hall transmits information is different from that of other Halls, and if a member of the Sacred Lower Hall betrays him, he will not be able to read the information transmitted inside the Watchroom.

In the end, Jiang Yugang also used some stupid methods to increase the intensity of secrecy, one method was to constantly change the password, and the other method was to add and delete secrecy methods, which certainly brought a lot of seemingly redundant work and brought a lot of burden to the members of the Secret Academy, but it was also effectively implemented by cultivating the core members of each branch or stronghold, and then educating other members through the core members.

Ah Zheng sealed the letter and immediately went to the lounge of the receiving point of the Mansi Village to find someone to send the letter back.

His ability division is mainly in reconnaissance, and traveling in the jungle is not his specialty, and at the moment the intelligence about the reinforcements of the Barbarian Temple Village is the most important thing, and there is no room for error, and the most reliable people must be found to take charge.

Originally, the most reliable person was naturally Duo Zi'an, the person in charge of the contact point, but now Duo Zi'an was nowhere to be found, so he could only find someone else to complete the task.

He walked briskly into the lounge, where a sturdy middle-aged man was getting dressed, apparently having just gotten out of bed.

The middle-aged man saw Ah Zheng walking in, and asked with some curiosity: "Ah Zheng, aren't you on duty?" Why did you come back so soon? ”

"There was an emergency, and Duo Zi'an came back, bringing important information that you need to send back." Ah Cheng looked serious and lied quietly. This is also a matter of no choice, after all, this information was obtained by his judgment, and Duo Zi'an, who should really provide accurate information, has no news at this time.

Let this middle-aged man know that the truth of this information is unpredictable, so it is likely that the next task of transmitting false information will be the next time, and there will be a lot of trouble at that time, and he will probably not agree.

In order to ensure that the information can be delivered to the destination Meng Yangcheng as soon as possible and smoothly, Ah Zheng chose to lie to deceive this middle-aged male member of the Secret Council, as long as the intelligence judgment is correct, he and the middle-aged male member of the Secret Council who is responsible for delivering the letter will not be dealt with, and if the information proves to be wrong, he will take the responsibility himself and not affect others. Ah Zheng thought so in his heart.

"Duozi'an is back? Didn't you see him back in the building? The middle-aged man asked suspiciously, he didn't see Duo Zi'an returning to the lead point.

The middle-aged man here refers to the main building where the lounge of the access point is located, which is considered the daily living place of the members of the contact point, and the bamboo building, which is disguised as an abandoned and dilapidated house, is generally called the "observation point" by the members of the contact point.

"The matter is urgent, he went directly to the observation point to find me, because there is no intelligence production method of our secret academy in the camp, and I need to urgently do intelligence processing so that I can carry out follow-up intelligence transmission." Ah Zheng continued to make things up.

This reason was very convincing, and the middle-aged man did not suspect it further, took the information in Ah Zheng's hand, and asked casually: "Is Duo Zi'an at the observation point now?" ”

Ah Zheng nodded: "Yes, he didn't have much rest in the second half of the night, so he simply fell asleep at the observation point." ”

"Okay," the middle-aged man nodded, making the final confirmation to Ah Zheng before sending the information: "This information, do you think it's 'urgent'?" ”

"Emergency" is the name of the secret science academy's system of evaluation of intelligence. The intelligence evaluation system is mainly divided into two aspects, one is from the urgency of time, which is divided into "ordinary", "urgent" and "urgent", in which ordinary intelligence does not have any priority in intelligence processing, nor does it have the ability to dispatch additional resources; Critical information, which can assign specific members of the Secret Council to immediately transmit information, and can also request a stronghold or part of the horse to help; Emergency intelligence, on the other hand, has the highest resource mobilization capability to serve it, not only to designate members to transmit intelligence immediately, but also to mobilize the highest priority for the use of horses along the entire intelligence transmission line.

Another intelligence evaluation system is from the perspective of the secrecy of intelligence, which is divided into "open", "exchange", "secret" and "top secret". Among them, "open" intelligence refers to information that can be disclosed, and sometimes even information that needs to be disclosed; "Exchange" intelligence refers to the information to be sent to friendly units, which is a special classification, this kind of information cannot be said to be open intelligence, and it is still confidential to ordinary other personnel, but because the information has to be delivered to other departments of Mang Castle, the Ming army or other trade objects and other friendly parties, and the handling of friendly secrecy is uncontrollable, so it is generally lower than the other two higher levels, and higher than the lowest level of secrecy "open".

Although the secrecy of other departments in Manggu Castle has nothing to do with the Secret Institute to a certain extent, it is still within a controllable range, but the entire secrecy system is still lower than that of the Secret Academy, although it may be due to human reasons, the secrecy has a certain uniqueness, and it is even better than that of the Secret Academy.

"Secret" information is the information that is transmitted within the Secret Academy, and it usually needs to be completely confidential, just like Ah Zheng's handling of the information of the reinforcements of the barbarian temple camp at present, which has a relatively high degree of secrecy.

Through the practice of Mengyangcheng, the basic conclusion can be drawn that under the noses of the other defenders of Mengyangcheng, the Secret Academy can carry out effective information transmission without being detected.
