Zhu Di was curious about this new thing and showed a strong interest.

He was born in the army and naturally knew the importance of confidentiality of official documents transmission, but looking at these dense numbers of big food, he couldn't help but feel a little headache. The more he did, the more he could understand the power of digital transmission.

Hao Fenglou smiled slightly, found a clerk and asked, "What is the secret book of this month?"

The clerk said: "It's "The Beautiful Wife Like a Cloud."

Hao Fenglou was ashamed and hurriedly looked at Zhu Di. Zhu Di was indeed very concerned and couldn't help asking: "What is "The Beautiful Wife Like a Cloud"."

"This..." Hao Fenglou wanted to give himself a few tricks. He was so mean. Why did he use "The Wife of a Beautiful Cloud"? Now he has shot himself in the foot, and his glorious image has disappeared.

But Zhu Di was not sure about it, and his appearance was very pure, which made Hao Fenglou feel even more guilty.

"Uh..." Hao Fenglou's old face turned red and he ordered the clerk to say, "Go and find a book."

The clerk found the book and handed it to Hao Fenglou. Hao Fenglou said with a shameless face: "Your Majesty, numbers are numbers. If you want to translate the numbers, you must have a secret book. The secret book can be changed frequently. For example, here in the camp, the secret book is changed once a month. This month is this book "The Beautiful Wife Like a Cloud". Your Majesty can try it yourself. Look at the number at the beginning, such as 5792, 57 is the page. Please turn to page 57."

Zhu Di took the book and was as serious as a child. He quickly turned the book to page 57, and the words inside were unsightly, but Zhu Di suddenly realized it and urged, "What's next?"

Hao Fenglou said: "The third nine characters are nine lines, and the second character behind is the second character. Look at what character is this."

Zhu Di moved his fingers up the book and murmured: "Shusheng Shen's naked twigs... are words, ha... are words!"

Hao Fenglou said awkwardly: "Your Majesty, you counted wrongly. This is the eighth line."

Zhu Di counted and was indeed wrong, so he moved to the ninth line and said, "It's based on the word."

After finding the first word, Zhu Di seemed to have discovered a new world. His old face was a little red, and he said with great enthusiasm: "Okay. I know how to decipher. Don't say it again. I will check it yourself next."

He sat down, took out a piece of white paper, first wrote a word, then looked at the number 7632 at the end. He turned to page 76, found the second word on the third line, and then wrote a word search with a pen.

He seemed to have found fun, and was completely trapped in it, and translated the official documents filled with numbers one by one. Finally, his handwriting was written on the paper: "According to investigation, there are suspicious figures in Datong Mansion. It is suspected of private iron trafficking, so I hope to check it again."

Zhu Di took a deep breath, then frowned and said, "There are chaos parties in Datong Prefecture?"

Hao Fenglou said: "These official documents are just trials. Now the Shenwu Guard has not been transferred to various places, so the official documents will naturally not be issued. They are just practicing for these clerks. Once they start working in the future, they will also avoid being in a hurry."

Using this novel method, one word by one, translated one smooth line, Zhu Di felt a deep sense of satisfaction. It seemed that he had not felt so happy for a long time. After all, he was bored in the palace for too long. Besides, Zhu Di only needed a little to immediately understand the benefits of this encrypted method of sending official documents. He realized that this method can not only be applied to Shenwuwei, but also has great use in future marches and wars. Official document transmission, especially some extremely important documents, can even decide a war once intercepted by others.

When Zhu Di was in crisis, he often used his method to use scouts to intercept the official documents of the Southern Army. After learning the intentions of the Southern Army, he grasped the movements of various units of the Southern Army. For example, some Southern Army horses asked for help, and they could quickly realize that this army must be on the verge of collapse. If they work harder, they would definitely defeat them. Some military horses also reported official documents and required that food and grass be allocated immediately. From this, the number of days of food and grass consumption of the other party can be calculated. The method of small groups of military horses constantly attacking the other party's food channels can make the other party's morale depressed.

Zhu Di can know the benefits here as he knows. He usually hates being robbed. Zhu Di's method of using this method has been tried and tried every time. He has taken great care in the transmission of official documents and military information. However, even if he is careful, he will eventually capsize. This aspect has always been a headache. Now, the method of decoding the big food numbers and secret books has almost completely solved this problem, because this method only requires a very small number of people to know the method of decoding, and then use any combination of numbers to form arbitrary books.

If you choose a book in the sea, you can turn these messy numbers into important official documents. Even if you are aware of it, the other party will be helpless and take a step back. Even if the other party knows the way to decipher the password, you only need to change a secret book and replace "The Beautiful Wife Like a Cloud" with "The Good Husband of the Ming Dynasty". The other party has to be confused again. If they want to decipher, they can only try it continuously from tens of thousands of books and hundreds of thousands of books. But when they decipher it, it will be a few months or even a year later.

Even if you don’t want the other party to know at all, then you can simply publish a book by yourself and write a piece of paper as a secret book. Then even if the other party intercepts his official documents and does not have a secret book, it is just like a god painting talisman.

In short, this was definitely the smartest way, beyond expectations. Zhu Di couldn't help but feel a little excited and picked up the numbers in the letter again and stared blankly.

However, Hao Fenglou began to wonder in his heart whether his image was completely ruined, whether His Majesty would suspect that he was not doing his job properly, or that he was too coquettish. His Majesty has always been serious and not a good woman, and he must be deeply disgusted with such messy things.

Thinking of this, Hao Fenglou took a deep breath and said seriously: "Your Majesty, I have something to report."

Zhu Di said: "You just say it's okay."

Hao Fenglou said angrily: "I am worried about the secret book. After 49 days, I have been working hard and forgetting to eat and sleep, and finally came up with such a wonderful way. But in order to keep it secret, I chose an absurd YIN book like "The Beautiful Wife Like a Cloud" as the secret book. It is because I am having my own difficulties. Your Majesty should know that choosing a secret book must be unexpected, so..."

Zhu Di said: "This "The Beautiful Wife Like the Clouds" is an absurd YIN book?" He picked up "The Beautiful Wife Like the Clouds" again. After reading it, he immediately threw away the book and scolded: "Who is the bad guy's mind, who is writing the book should be ordered."

Hao Fenglou burst into tears. It turned out that the emperor realized it and was just now focused on deciphering it. He didn't notice what kind of book it was. Now he was better. He didn't open any pot and would pick up any pot. This was the rhythm of being a shame to the end.

Fortunately, although Zhu Di denounced the author of YIN, he did not punish Hao Fenglou. He looked at Hao Fenglou deeply and said, "I have benefited a lot from this trip. It can be seen that you have indeed spent a lot of effort, which is very rare. It is not easy for you. While being in the Jinyiwei, you still have to handle this Shenwuwei, which can make me look at you with admiration. It seems that I have not cultivated you in vain."

These words finally comforted Hao Fenglou's heart. He hurriedly said, "I am just doing my best to make fun of His Majesty."

Zhu Di shook his head and said, "Others don't understand, but I know how difficult it is. Especially this secret book, which makes me even more amazed. The matter must be kept secret now and it is not advisable to be publicized. Although I have not seen those strong men of your Shenwu Guard, just this is a refreshing thing. Today's time is limited, so I can only come here. I should go back to the palace. What needs does Shenwu Guard have in the future? Even if I tell me, I can see that you are truly willing to do your best to do your best. But if you ask for something, I will try my best to satisfy you."

Zhu Di no longer consciously attached more importance to Shenwuwei, and the weight of Shenwuwei in Zhu Di's heart has also greatly improved.

Hao Fenglou also realized that his level had improved invisibly. He thought and couldn't help but say, "Your Majesty, I do have a request."

Zhu Di said: "You said."

Hao Fenglou smiled bitterly and said, "Your Majesty should know that the cost of this Shenwuwei is like flowing water. In just half a month, before the official start of office, he has already spent thousands of silver. For example, those blacksmiths purchased a large amount of carbon and ore and tried to produce pig iron. They also purchased a large amount of medical books and even some lonely books for the doctors. In addition, there are so many people to eat and drink. Although there is a silver supply in Donghuamen, I think that after the yamen is completed in the future, the brothers will distribute it to various places, and the money they will spend even more.

After all, the Shenwu Guards to be built are unprecedented. If they want to make them useful in the future, even if they are one to serve His Majesty, the money they spend must be huge. Therefore, I have an idea to ask Your Majesty to make sure that the Shenwu Guards will do some business in secret, such as the refined pig iron, which can be sold in the market. Of course, I will definitely take other measures to cover up my eyes and ears. It is just to smelve iron privately and sell it in the market. After all, it violates the laws of the ancestors, so you must ask Your Majesty to nod in this matter."

Zhu Di pondered and said, "Pig iron involves national economy and people's livelihood, and should not be underestimated. But then again, the court is really in urgent need of iron at present. Now everything is in a mess. If I want to expand my territory, I must use pig iron to forge weapons. Farmers also need iron to farm. Shenwuwei is also a yamen. It is not wrong to set up a construction plan yourself, but you must have a number yourself and try not to be noticed."
