Compiling a military book is not a simple matter, and a general military book must contain such basic contents as the selection and organization of troops, the arrangement of troops, the methods of training, the command system, the rewards and punishments of military law, and weapons and equipment.

If you write a book out of thin air, I'm afraid ten years is not enough!

Fortunately, Zhang Bin already has a certain foundation, what "Sun Tzu's Art of War", "Sun Bin Art of War", "Liutao", "Sima Law" and other veteran books he has already read, "Ji Xiao Xinshu" and "Records of Military Training" He is even more clear, coupled with the experience of later generations, it is not impossible to compile a military book in two or three years.

Of course, he is not purely borrowing plagiarism, at this time, the military books that combine cold weapons and hot weapons are also "The New Book of Discipline and Effectiveness" and "Records of Military Training", if he purely borrows from plagiarism, then people might as well read "The New Book of Discipline and Effectiveness" and "Records of Military Training".

He plans to combine the existing military books with the experience of later generations and the current level of weapons and equipment of the Ming Dynasty to compile a brand new military book.

For example, in terms of recruiting and organizing, he plans to break the traditional method of recruiting and organizing troops, and use squads as the basic unit, that is, one mandarin duck formation per squad and twelve people.

For another example, in terms of arranging troops, there are not only mandarin duck formations, but also new formations such as gun formations, infantry and artillery joint battle formations, and infantry and artillery joint battle formations.

For another example, in terms of weaponry, he plans to add more practical thermal weapons such as mines, grenades, and new breech guns.

In terms of editing the whole book, he is also ready to break the tradition of text-only descriptions and use pictures and texts.

He originally thought that he would be a little choking to finish compiling the entire military book in Jinling alone, but he never thought that as soon as he started compiling it, someone would immediately join in, and more and more.

The first to join is Qi Yin, a veteran of the Qi family's army, he has stayed at home for decades and is not sitting stupidly all day, many times, he is also studying the war book battle formation, as soon as Zhang Bin said that he wanted to compile the war book, he immediately became interested, and because he has commanded a lot of battles, many ideas are even more thoughtful than Zhang Bin.

Immediately after Qi Yin, Bi Maokang also joined, he was a rare weapons expert in the late Ming Dynasty, and his understanding of muskets, artillery, and chariots was much more comprehensive than Zhang Bin's.

Then, Cao Huachun was also interested, of course, he could make a little suggestion at most, because he had also read some military books, and there was only that time to get out of the palace at this time.

In the end, there was another person who he didn't expect to join in the writing of the war book, and this person was really completely unexpected by him.

On this day, he was discussing the structure of the new chariot with Bi Maokang in the study, when Sun Biao, who was on duty outside, suddenly ran to the door of the study and said loudly: "My lord, my protégé Chen Zilong asks to see me." ”

Zhang Bin is strange, didn't he let them go back to study hard and prepare to participate in the imperial examination in two years, why did Chen Zilong come over again at such a short time, he was slightly puzzled: "En, let him in." ”

After a while, Chen Zilong hurriedly walked into the study, and he was still holding a box containing a prayer post!

After the two sides saluted, Chen Zilong respectfully held the box up to him, and said loudly: "Teacher, Master Xu Guangqi, the right attendant of the original Ministry of Rites and a bachelor, wants to visit you, I wonder if you are free?" ”

Xu Guangqi, another famous minister!

When Zhang Bin heard this, his eyes were about to pop out, this Xu Guangqi is a great person, he is proficient in mathematics, astronomy, calendar, agriculture, water conservancy, art of war, weapons, etc., and is one of the most famous scientists in the Ming Dynasty.

What is even more commendable is that the official is honest and honest, diligent and good, not the kind of nerd who can only do learning, the two generations of emperors of Tianqi and Chongzhen have appreciated him, in the Chongzhen Dynasty he is the official to the Ministry of Rites and Wenyuan Pavilion scholar, the second assistant of the cabinet, but unfortunately he was born in the late Ming Dynasty, if he was born in the early Ming Dynasty or the middle of the Ming Dynasty, he alone can change the fate of the entire Ming Dynasty!

Such a famous minister actually wanted to visit him, Zhang Bin was so excited that he didn't know what to say, he trembled and picked up the greeting post in the box and looked at it, sure enough, it was Xu Guangqi, he was looking for himself to ask about the cultivation of potatoes and sweet potatoes.

It turned out that at this time, Xu Guangqi was compiling the "Complete Book of Agricultural Administration" at home, and a student found him Zhang Bin's "Potato and Sweet Potato Planting Minutes" for reference.

Zhang Bin was stunned when he took the post, and Bi Maokang suddenly suggested: "Brother Shuangquan, Lord Xu is highly respected, I am afraid it is not appropriate to let him come to visit, why don't we visit him." ”

When Zhang Bin heard this, he immediately nodded and said, "Brother Meng Hou is right, how dare you let Lord Xu visit him in person, we should visit him." ”

Immediately afterwards, he asked Chen Zilong: "Are you familiar with Master Xu?" ”

Chen Zilong hurriedly bowed his hand and said: "Students often go to Master Xu's house to listen to lectures, and Master Xu takes great care of students. ”

Zhang Bin thought about it for a while, and then said to Chen Zilong: "Maozhong, you rest here for a day, and we will go to visit Lord Xu together tomorrow morning." ”

Chen Zilong naturally readily agreed, and there was nothing to say all night, and the next morning, Zhang Bin and his party went straight to Songjiang Mansion on horseback.

Jinling City is about 600 miles away from Songjiang Mansion, if the road is smooth, you can arrive in two days with a fast horse, but on the way, the river is vertical and horizontal, and you need to ferry from time to time, and everyone beat the horse and galloped for nearly three days before arriving at Shanghai County, Songjiang Prefecture.

Chen Zilong often comes here to listen to lectures, so he is naturally familiar with Xu Guangqi's family, he took Zhang Bin and others to Xu Guangqi's manor outside the county, and he didn't need to pass it on, he directly led everyone to tie the horse, and then casually found a family member to ask, and then walked to the trial farming opened up by Xu Guangqi.

Xu Guangqi is not only a scientist, but also a foreign language scholar, many books on mathematics have been translated by him, and he also learned this manor and villa from foreigners.

After walking on the field path for about a tea time, they came to a rice field, which was nearly dusk, and only one of the old farmers was working in the fields.

Chen Zilong shouted directly to the old farmer in the field: "Sir, sir, the teacher and Master Bi have come to visit. ”

When Zhang Bin heard this, he was really shocked, the old farmer working in the field turned out to be the famous Xu Guangqi!

Xu Guangqi looked up and saw that the path on the edge of the field was full of people, so he hurriedly took a few steps and praised him and said, "Dare to ask which one is Master Zhang." ”

Zhang Bin hurriedly arched his hand and said: "Zhang Bin, a member of the Qing Officials Division of the Military Department of the Southern Metropolis, has seen Lord Xu. ”

Xu Guangqi hurriedly replied: "I have been looking up for a long time, Lord Zhang is so young, he didn't recognize it for a while, forgive his sins." ”

Immediately afterwards, he bowed his hand to Bi Maokang next to Zhang Bin and said: "Dare to ask Your Excellency, it is Mr. Dongjiao, a famous man in Huizhou." ”

Bi Maokang hurriedly replied: "Don't dare to be, don't dare to be, it's just Huizhou Bi Maokang, just call me Menghou." ”

Xu Guangqi confessed for a while, so he washed his feet with the water in the field, and then walked directly barefoot and took Zhang Bin and others to the villa in the middle of the manor.

It's amazing for these three people to meet, Zhang Bin has the knowledge of his previous life, whether it is the cultivation of potatoes and sweet potatoes, or mathematics, geometry, astronomy, calendar, and even the art of war and weapons, they can all be called experts at this time, plus Bi Maokang is a rare weapons expert, and the three of them chatted about it.

They talked about agriculture, the art of war, mathematics, weapons, and all the way to the "Complete Book of Agricultural Administration" and "Introduction to the Drills of the Ming New Army".

Zhang Bin really didn't expect that a copy of "Potato and Sweet Potato Planting Minutes" would make him unexpectedly gain a super heavyweight political ally!
