The next day, while sleeping Jiang Jie was urging outside, Bailiyan turned over and got up with sleepy eyes, still yawning:

"What time is it?"

"It's already time, my lord, and my subordinates didn't dare to wake you up when they saw that you hadn't closed your eyes for a few days."

"Hmm......" Bai Liyan yawned again, stretched her waist, and asked vaguely: "What do you call me at this time?" ”

"Lord Hui, I found this just now by checking and capturing enemy ships."

Jiang Jie handed over a Jin Xuedi book, about a finger thick, the paper was very rough, it was a simple paper made of straw and tree bark, and the texture was very poor. On the title page of the booklet is written Jin Xue Diwen, which means "General Essentials of the Art of War", seeing this, Bai Liyan couldn't help but be confused:

"Who found this book?"

"A few old pawns found this book when they searched, and the old pawns didn't know the brute characters, so they still left it on the ground, but they found that half of the book was brute characters, and the other half was my original Chinese language. After handing it over to his subordinates, he found the top-secret content of our army's martial arts hall. ”

"What!" Bai Liyan was taken aback when she heard the news, and broke out in a cold sweat.

He knew very well that the internal art of war books copied by the lecture martial arts were taken back to the lecture hall library after each use, and it was very unlikely that they would flow to the outside world, let alone travel more than 20,000 miles across the ocean to appear in the Jin Xuedi people's art of war books.

Part of the content of the written teaching of the lecture hall was carefully selected from the books on the art of war that could be collected in the current world, and part of it was selected by Bai Liyan based on the experience of the previous life, and it was impossible for the outside world to be similar. Jiang Jie is familiar with the content, and it is impossible to look away.

When I opened this book, it was indeed a Jin Xuedi text, a Chinese original, with rough annotations. Among them, there are many distortions in the annotations about the content of the lecture hall, and the translation and understanding are completely different.

Such as "all those who fight, with the right fit, with the odd victory." Those who are good and surprising are as infinite as heaven and earth, and inexhaustible as rivers and seas. In the end, the sun and the moon are also. Death and resurrection, four o'clock is also. The sound is not more than five, and the change of five voices is not better than listening; The color is not five, and the change of the five colors is invincible; The taste is not more than five, and the change of the five flavors is indispensable to taste. "The fallacy is misinterpreted as a relationship between numbers, as the saying goes, there are only three things, and in Jin Xuedi's textbooks, it has become only one, two, three, four, five.

Another example is "the loss of land, the loss of people and land, the loss of people and land, the loss of people and land", Bailiyan listed it as a chapter on governance and economy, focusing on the relationship between people and land, land and people, people, land, and economic national strength.

The core content is that "people" are the fundamental resources of all military, political, and economic resources, and no matter how much land there is without people, they cannot hold on to it. Therefore, the loss of people's power is more threatening than the loss of land, and the relationship between people, land, and economic and national power is elaborated in the lecture.

But in this book, it has become an attitude of coexistence between man and land, and the attitude of retribution and death will fight a decisive battle with the enemy, otherwise the land and people will be lost.

Seeing this, Bailiyan was somewhat relieved.

There is only the original text and no annotations in the internal books of the lecture hall, and each lecture is passed down orally by Baili Yan, if there is no personal experience and correct understanding of the ideas, in the absence of historical allusions and prerequisites, it is difficult for outsiders to know the secrets of the lecture hall.

Even if you get the internal information, many of them are literal and half-understood. From this, it can be concluded that the content was not leaked by the military attaché class, or the library keepers, or other princes who stole the content and were taken away by the Central Plains thieves.

Counting the time, it will take five or six years since the opening of the lecture martial arts, from stealing back the materials from the Central Plains to getting back the local research and publication of Jin Xuedi, how can it be two or three years, so calculated, this incident still happened before Bailiyan left Xianguo.

In this way, the suspicion of the Jin State is undoubtedly the greatest, and after the Jin State steals it back, it may not be intentionally stolen by the Central Plains thieves.

Thinking of this, Bai Liyan's face became more and more ugly, and he said:

"In addition to my lecture on martial arts, there are also military systems and military art created by famous generals of other countries in recent years, most of which are the essence of the Central Plains Art of War. I didn't expect the Jin Xuedi people to infiltrate the Central Plains to the point of pervasiveness, which is incredible! ”

"My lord, since the people of Jin Xuedi can obtain this book from my Central Plains, why are they still defeated in battles with our army?"

"Huh!" Bai Liyan sneered: "Its meaning is far from the essence of the original Chinese text, and the difference is thousands of miles, and its interpretation is contrary to the meaning of the original text, and it naturally does not know the mystery." Those who can really understand the original Chinese texts either do not know military affairs, or have no allusions to refer to details, nor can they personally feel the essence of the Central Plains' thoughts, and they can only know the subtlety of the Central Plains Art of War. Even if he uses this kind of half-understood art of war, not only will he not be able to win, but he may also mislead his children and suffer from it. ”

"Isn't that a shot in the foot?"

"Not only is it lifting a stone to shoot yourself in the foot, most of them have already suffered from it and cannot extricate themselves. Put this book away and it will be of great use in the future! ”

"No!"

Hurriedly washed his face with cold water, and followed Jiang Jie to the deck, the temperature was obviously lower, the warship of the Jin Xuedi people had retreated twenty miles away, and there were still a large number of floating corpses floating on the river, and the smell of gunpowder smoke still remained in the air.

Jiang Jie put a gray fur robe on Baili Yan's shoulders at this time:

"The weather is getting cold today, so don't you catch a cold."

"The wind is sluggish and the water is cold, and the strong man will never return once he is gone...... It's been so fast, and before I know it, it's been almost two years. Bai Liyan's face was gloomy, as if she was a few years old in an instant.

Jiang Jie nodded in frustration:

"Hmm...... It has been more than two years since the defeat of Duhui, and I don't know if I can return to Xianguo. ”

"In nearly 20,000 miles, it is very difficult for hundreds of thousands of people to return to the Central Plains alive. But don't be discouraged, there is no way to do it. It's a big deal that our army also learns from the Huns, and its roots are attributed to Xia, and it is crisscrossing the grassland, and it has been fighting with them here for decades! ”

"My lord, who are the Huns?"

"You don't know this, it was a long time ago in another world, a powerful nomad wandering on the grassland, with the same roots and species as the Central Plains, because they had cut off the news of the Central Plains and became a family of their own. Go, get me some hot rice. ”

"Yes, sir."

The Xiongnu originated in the Xia and Shang dynasties, and in the early days it was also a branch that expanded the territory of Chinese civilization and migrated northward.

The coalition army was trapped in the south, the news was cut off, and the clothing, food, housing and transportation needed to be plundered, it is difficult to say that the population will gradually increase in the future, and it will not be able to return to the Central Plains in the north.

Taking advantage of the great injury of Jin Xuedi's vitality, the coalition forces rushed to repair the warships in the morning, and more than ten sunken ships were floated from under the water one after another.

In the afternoon, the temperature rose somewhat, and Bai Liyan flipped through the so-called "General Essentials of the Art of War" in the cabin, and the translation and distortion of the contents were seriously problematic, with serious subjective assumptions and assumptions.

Before and after, Jiang Jie suddenly came to report:

"My lord, my lord, Jin Xuedi's army has run away!"

"Ran!"

Bai Liyan was quite surprised when he heard the news, he felt that with the temperament of Jin Xuedi, he would definitely not give up, could it be that Mooney learned of the retreat order after the defeat?

Walking to the deck, the telescope could see that the enemy ship had turned around twenty miles away, intending to flee westward.

"Jiang Jie, has anyone recovered the horses that were put on the south bank yesterday?"

"It's all taken back, what do you command?"

"Go, let people ride horses and carry enough rations to the north and south banks, and see where their sailors on the shore go."

"Do you suspect that Jin Xuedi is cheating?"

"If you think about it, they have many times as many troops as I have here, and even now, they have more men than ships, and they still have many times as many troops. However, our army seized warships for several days to repair the sunken ships, and coupled with casualties, the number of troops was seriously insufficient.

If we were to bring all the ships back to Dranki, the forces would be diluted by the ships, and even if they were rowed downwind, at most two shifts would be rowed much slower than them, and if they came in pursuit, we would not be defeated. ”

Seeing that the coalition forces continued to salvage the sunken ships, most of them also expected that the coalition forces would get all the ships away, but on average there were not a few people on each ship, so they pretended to be defeated, so that when the coalition forces fled eastward, they followed the strong attack

"Most of them are clever and think that our army is seriously underwhelmed, and they want to pretend to be defeated, so as to take advantage of the opportunity to follow the attack."

"It is said that this is the case, but it is so simple and reasonable, but they don't want to think about it, if they are tricked by our army, they will not bring disaster upon themselves."

"Then you say, if our army goes east, how can we make them fall for it."

Bai Liyan asked rhetorically, Jiang Jie shook his head after thinking for a while and said:

"This ...... The subordinates are stupid and don't know, and they ask the adults to make it clear. ”

"You are so shrewd and don't know it, and how can they know? Do you think that Ben will be a bag that can be conjured out of thin air? ”

"Is there really nothing you can do?"

"Not exactly, but it takes some effort. How many ships does our army have at the moment? ”

"Five more self-sunken ships were salvaged before, and now there are more than 240 ships, and there are more than 40 ships that need to be salvaged."

"In this way, as soon as it gets dark tonight, every two 3,000-stone ships, three 2,000-stone boats are arranged in a group, three 2,000-stone boats are in the middle, two 3,000-stone boats are placed at the head and tail, and the five are closely connected by ropes, and the head and tail boats are equipped with oarsmen and sailors, and the middle three 2,000-stone boats are lowered with empty sails, so that two big ships take three small boats, and the manpower of the small boats can be transferred to the big ships, and the speed will not be slow."

"Eh, what a wonderful plan, my lord!"

"Go quickly, let the cavalry go ashore, I pondered, most of the Jin Xuedi people will have to go out of the waterway for at least a day before our army can rest assured!"

The tugboat method is now mostly seen in light boats and small boats, and large ships are rarely used, one is that the impact force of large ships is much greater than that of small boats, and the destructive force is greater.

Second, there is no need, in reality, there are very few extreme cases of several ships towing and moving together. Third, tugboats should also pay attention to technology.

If the distance between the two boats is too short, the shock wave generated by the movement of the front boat will be transmitted to the rear boat through the hydraulic force, increasing the resistance of the front boat. And the axes of the two ships are not easy to coincide, so it is not convenient to drive.

If this method is used for the towing of large ships, the ropes must be put longer, and the empty cargo of the rear ship will reduce the load, but if this operation is not done properly, the rear ship will still hit the front ship, or even the rear ship will run aground, and it is impossible to tow more ships in a team.

In fact, the towing of the big ship should be shortened as much as possible, and the end and tail should be connected, so as to avoid collision, and at the same time, because the hull of the big ship belongs to eat deeper, the impact of the shock wave is there, but under the pressure of the hull load, the shock wave is not easy to cause the hull to yaw and twist.

At the same time, at the end of the fleet, manpower is arranged to control the ship to form the head and stern ships to be controlled at the same time, so that the axis of several large ships in series can be basically kept on one axis, so that the bending and torsion will not cause accidents caused by the increased resistance, and the rear ship can also play a deceleration role.

For example, the fleet of goods on the Beijing-Hangzhou Grand Canal adopts this method, the first few boats drive diesel engines, and the back pull twenty or thirty boats to stop the boats, and the fuel-saving run is not slow.
