For a moment, everyone couldn't believe the authenticity of the information, because the amount of information contained in it was too large.

It was Zhu Zhanji who calmed down first and asked, "Where are the young army scouts?" How many people return? ”

The herald took out a letter and held it above his head and replied: "This person has traveled more than 10,000 miles back and forth, and is now recuperating in the forward camp. When he came to the camp with a low position, he was alone. This is this person's reply, instructing His Royal Highness to receive it personally. ”

The forward battalion is still more than 300 miles away from Hulan and hypothermia, and I am afraid that I will not be able to see the scout himself at this time.

Zhu Di couldn't help but ask: "Zuo Dudu actually sent the scouts so far away, how can they survive?" How do I send a message? ”

In the barracks tent, Zhu Di called him the governor of the left capital, Zhu Zhanji stepped forward to take the letter handed by the scout, and also replied as the governor of the left capital: "The training of the young army on weekdays is mainly based on survival and concealment in the wild. ”

Liu Sheng couldn't help but ask: "Thousands of miles behind enemy lines, how to transmit intelligence?" ”

"Go straight behind enemy lines, and there is no way back."

Although Zhu Zhanji said it simply, most people understood it as soon as they heard it. In other words, after these scouts get the information, they can only return and will not be sent back.

Liu Sheng asked again: "How to ensure the accuracy of the information and not tamper with it by the enemy?" ”

"Three scouts will be sent back at a time, and all three will have the same information. First, ensure that the information is not unexpected, and secondly, ensure the accuracy of the information. ”

Zhu Di said: "This matter will be discussed later, let's see what is said in the secret letter first." ”

Zhu Zhanji came to Zhu Di's side, opened the wax seal, and unfolded the secret letter rolled into a roll.

Here are several topographic maps, each of which, in addition to the distribution of people in the Northern Yuan Dynasty, important peaks and rivers are also marked with latitude and longitude.

Of course, this latitude and longitude will not be the primordial meridian of the later generations as the standard, but the palace of the Ming Dynasty should be the starting point of the meridian, and the latitude is still based on the equator.

Therefore, even if the drawing of the map is not accurate, Zhu Zhanji can easily judge the reasonable direction and terrain.

With these maps, not only can we know the current distribution of the Northern Yuan people's forces, but we can also know where to move in order to inflict greater damage on the other side.

After introducing this information, Zheng Heng asked with some suspicion: "Your Highness...... No, Governor Zuo. Do the scouts of the Young Army have the ability to draw maps? You can also pull the stars! ”

Zhou Nan asked rhetorically: "If you don't know this, are you still a qualified scout?" ”

Zheng Heng had nothing to say, but his interest in Zhu Zhanji's young army immediately increased, and he turned back to Zhu Di and said, "Your Majesty, Your Highness's move is undoubtedly to create a reconnaissance ability in the army, and I hope Your Majesty can promise to spread the astrological technique in the army." ”

Zhu Di said with a smile: "I'll talk about this later." I also know a little bit about the young army's star-pulling technique, which is not the same as Si Tianjian's star-pulling technique. It's just that not many people know about it, so it hasn't been promoted yet. ”

Because of the appearance of "Magellan", Zhu Di knew the general principle of the sextant and relying on the sextant to position. However, Zhu Di did not want to promote this technology, but Zhu Zhanji had already spread it.

However, now it seems that the promotion of this skill in the army can have a very big effect.

There is also some pressure in his heart, although Da Ming can continue to keep the star pulling technique and this kind of sextant positioning secret, but this technology is passed down from Xiyi, and they have mastered this skill, but it is meaningless for Da Ming to keep it secret.

It's just that this topic is a little out of place when the two armies are facing each other.

So, everyone's attention quickly returned to the upcoming big war.

If the army of Warat does not move tonight, they will certainly move tomorrow, and they will not delay until the day after tomorrow. Because if the forward battalion returned from the mouth of the three rivers, the current 30,000 Varat cavalry would be even more passive.

When Zhu Zhanji came out of the big tent, it was already a child's time, but at least more than half of the soldiers did not sleep, on the one hand, to prevent the Warat people from robbing the camp, and more importantly, in the face of the pressure of the war, making it difficult for countless people to sleep.

Especially those generals, most of them can't sleep, but those veterans who have experienced a hundred battles, who should be on duty, should sleep.

When he set off from Beiping, the four daughters of Fenghua Xueyue did not accompany him, and Zhu Zhanji had no choice but to ask those eunuchs to help him boil water and boil herbs every day to take a bath.

Lying in the hot tub, the hot weather made him sweat profusely. But the nourishment of the crisp numb brought by the herbs made him reluctant to leave the water at all.

He was not worried about this war at all, because Zhu Di won all five Northern Expeditions.

But this kind of grievance also made him extremely depressed.

obviously has the strength of flat pushing, but because of low productivity, he can't give full play to his strength.

The army of nearly a million did not dare to disperse too much, but when they gathered together, they moved slowly, and could only force the Warats to fight with them in a scoundrel way.

If there had been a handy and easy gun at this time, the total number of these Warats, Tatars, and Uliangha would have been three million. As long as the logistics supply can keep up, a cavalry of 50,000 people can kill all these Northern Yuan people.

It seems that after going back this time, it is time for me to put the plan for improving the guns on the table as soon as possible.

Industrial upgrading can be delayed, at least a batch of easy-to-use firearms must be made first.

Not to mention that the modern rifles of later generations, even if they are the same arquebuses as the later generations of earth, are much better than the current ones.

The biggest problem now is the casting of the barrel.

No electricity, no motors, no machine tools. If you want to make a good barrel, the difficulty is not ordinary.

Now the barrel of the Ming Dynasty can only rely on skilled technicians, who first cast it into a grooved ring iron, and then polish it out little by little with a file.

Then another piece of iron is used to seal the groove, and the outside is sealed with an iron bar, which means that there must be two layers to ensure the closure of the barrel.

However, there was no uniform standard for these barrels, so the quality of the guns was uneven, and the skill role of the technician was infinitely expanded.

However, it is almost impossible to unify standards according to current technology.

Zhu Zhanji came out of the water, put on a close-fitting robe, and then lay on the table to write and draw.

He didn't remember where he had seen a waterwheel used as a power to drill the barrel of a gun, and Yingtianfu was close to the Yangtze River and had abundant water resources.

But when he really wanted to design this device, he found that it was not the way out.

Because in order for the power of the waterwheel to meet the requirements, the waterwheel must be large and strong. And such a waterwheel, not to mention the transmission device, just the core bearing is not what can be built now.

It can even be said that it is more difficult to build a qualified bearing than to build a gun.

And the gears of those transmissions must also be made of steel, and the wooden transmissions cannot carry the drill bits that can drill the barrel.

On the contrary, it is a drill bit, which is not difficult for Zhu Zhanji.

Because the best material for drill bits is tungsten alloy steel, the main components of tungsten, nickel, cobalt, niobium, titanium, and tantalum are not lacking in Daming. When the requirements are not high, the manufacture of tungsten steel is nothing more than a little more experiment.

What's more, now there is no need for too complicated processes, only tungsten and steel need to be proportioned, which is stronger than ordinary steel.

The material process can still be tested by memory, but the mechanical processing process is completely impossible to solve by relying only on memory.

"Your Highness, it's time to sleep. There may be a big war tomorrow, so you have to recuperate! ”

Zhu Zhanji looked at the dark sky outside, because the clouds were thick, and there was not even a little light.

"What time is it?"

"It's almost a moment ugly."

It's 12:45. Zhu Zhanji thought about it and put away the waterwheel diagram he had drawn. "Sleep alone, you have these things in my draft box."

Li Liang responded, he didn't do things by Zhu Zhanji's side on the first day, he abided by the rules set by Zhu Zhanji very well, and he was not afraid that he would leak secrets.

Zhu Zhanji entered the inner account, sat down on the mattress spread on the ground, and began to meditate.

The breath is running, there is no distraction, according to the Taoist breathing method, within a few minutes, Zhu Zhanji entered the realm of two forgetfulness of the characters.

In the early hours of the morning, the Warats once again appeared on the slopes of the northern part of the Kulan Hypothermia, and made a condescending assault.

However, although it was early in the morning, the Ming army was already prepared. As soon as the drums sounded, the outlying sergeants on duty waited for their work and set up a gun array.

Seeing that they could not take advantage, they made another arc outside the range and returned to the camp.

The sky was getting brighter, and when they saw the Warat army appearing on the hillside, everyone's emotions were a little depressed, and everyone knew that a big war was about to break out.

However, these hundreds of thousands of soldiers are veterans of a hundred battles, and their number is far greater than that of the Warats, so they are not panicked at this moment.

Their stability also relieved the people, and the leaders of the gang were also preparing breakfast under the organized arrangement.

On the earthen city wall, Liu Sheng looked at the Wara cavalry that was torn into a long dragon several miles long in the distance, and took the initiative to ask for battle. "Your Majesty, the army of the Warat people has all appeared, and the minister is willing to be the vanguard and lead the troops to give them a plough court to sweep the lure."

Zhu Di looked at the deterrent formation of the Warat people and smiled: "Don't worry...... At this time, it is the Warats who should be in a hurry. If they don't attack now, we'll wait for the soldiers to have breakfast. ”

Everyone laughed, but at this time, Zhu Di smiled again. "Chen Mao, Wang Tong."

The two immediately came out of the ranks, bowed down and bowed: "The minister is here." ”

"The two of you lead the left post, the left sentry, and reorganize the army on the west side, waiting for my order."

"Yes!"

"Li Bin, Tan Qing."

"The minister is here."

"The two of you lead the right outpost, the right sentry, and replace the five military battalions to replace the front battalion to base the enemy."

"Yes."

"Liu Sheng."

"The minister is here."

"You lead the Shenji battalion and reorganize the army on the east side. Remember, drive the Aru Taibu in the front, if you don't obey, just do it. ”

"Obey."

Zhu Zhanji watched Zhu Di dispatch troops, not only did he not have fear in his heart, but he had a sense of excitement and pleasure.

It's finally time for the war!
