In the army, there has always been a saying that the army is in formation. Especially on the frontal battlefield, tens of thousands of troops on both sides hedged against each other, but it was not a group fight on the street, fighting indiscriminately. Only the rabble will fight indiscriminately, and the real army pays attention to the military formation. In addition to the level of sophistication of equipment and the level of training of soldiers, whoever uses the military formation like an arm and a finger will have an absolute advantage.

This is also an important condition that distinguishes him from a fierce general and a commander-in-chief.

The army was originally a collection of people to kill, and the military array was born because of this.

However, in the final analysis, the fundamental point of the military formation is nothing more than a training. Thousands of people live and die together, exercise a considerable tacit understanding, advance and retreat in unison on the battlefield, and kill together, so that the commander can be like an arm and a finger, and achieve the effect of destroying the enemy and destroying the country.

The mystery of the mortal military array ends here, and there is no mysterious reason.

However, the truth of the Five Elements Fist Sutra is the finishing touch, and it blesses the military array with extraordinary features.

Although the Five Elements Fist Sutra is only a mortal martial arts exercise, this Fist Sutra is not created by mortals, but by Zhao Yu, an immortal monk. To say that it is a martial arts exercise is to belittle it, but the real mystery is actually the method of building the foundation of the immortal road.

Although because of the root nature, it is difficult for hundreds of billions of people to produce a monk. But the Five Elements Fist Sutra is combined with the Five Elements, and there is a principle of mutual reciprocity and mutual restraint. It's just a skin, but it's also a skin that makes sense.

As Zhao Yu said, unconsciously, the use of the Five Elements Fist Sutra in the army has already conformed to some of the mysteries of the formation.

Of course, if Zhao Yu didn't point this out to him, maybe for hundreds of thousands of years, it would be difficult for them to find the real beauty in it. Although Dian Wei felt that he could invoke the strength of the soldiers under his command, if the five elements of the soldiers under his command were unbalanced and there was no formation combing and blessing, it would only be a feeling, and it would be impossible to achieve it.

Cao Mengde's doubts inspired Zhao Yu to have many new ideas.

He said: "To realize the truth of the Five Elements Fist Sutra in the army, the formation diagram is the key. If there is no formation map, the army will have a tacit understanding, and the soldiers will sense each other, and they can advance and retreat together, but it is absolutely impossible to set up a large array, and the strength of the whole army cannot be gathered in one person. And if the formation can stand, it can be broken. As long as you know how to break the formation, you don't have to be afraid. ”

Zhao Yu said, thinking even more in his heart: "So... I refined a set of five-element array flags, and with the power of magic weapons, he sensed each other, and the formation was undoubtedly broken. ”

Then he said: "Meng De will find me some fine silk, which can weave five three-foot-wide pennants, and spiritual wood... Forget it, you definitely can't find the spirit wood. I'll figure it out. You bring the silk, and I will refine a set of magic weapons for you. With the magic weapon in hand, let the Five Elements Army Formation be broken. ”

Cao Mengde was overjoyed, and he didn't mention it again and again.

For Cao Mengde, the original doubts were completely solved at this time. Although there are pros and cons, the disadvantages can be solved, only the pros remain, what is there to worry about?

Then we started chatting.

Cao Mengde said: "It's not as good now as it was then. High-yielding and improved varieties have long been spread in Yanzhou, and although one bite has annexed the two prefectures and several counties, there will be no shortage of seeds. In the past six months, Wen Ruo and I have been busy with our feet not touching the ground, especially in farming, and we have a lot to worry about. Fortunately, Wen Ruo is talented, and there are dates, otherwise I would have to scratch off one end of my hair. ”

"What about the road?"

Zhao Yu smiled: "Transportation is the key. The more convenient the transportation, the stronger the ruling power of the government. When you encounter an emergency, the faster you can react. As for commerce, it is also more because of circulation. The benefits are indescribable. Agriculture-oriented, business-oriented, all indispensable. ”

"I know that. Cao Mengde twisted his beard and said: "It's a pity that the cement output can't keep up." I'm going to build three avenues first. Starting from Puyang, one to the east, until the sea. One to the south, until the river. One goes west, until Yuhangu Pass. ”

Zhao Yu bowed: "Cultivate the main trunk first, and then take your time later." When the road stretches into the countryside and leads in all directions, tsk..."

Cao Mengde couldn't help but be fascinated: "In this way, it is the foundation of the prosperous world!"

Xi Zhicai also sighed: "If it extends in all directions, the end is as far as the countryside, and it is connected to the main road, you can go wherever you want, I don't know how convenient it is." ”

"At least five years. Cao Mengde was a little helpless: "There are only three backbones, adding up to more than 10,000 miles, not waiting for leisure." Manpower and material resources are costly. ”

"Make a plan first, just implement it, and there will always be a day when it will be realized. ”

Zhao Yu said: "This farming work is like a person's muscles, and the road is like a person's blood vessels." Only when the roads are smooth and the blood flow is unimpeded can the real prosperity be brewed. ”

Zhao Yu originally wanted to talk about industry or something, but when the words came to his lips, he still held back. Industry or something, for the time being, it's still a little far away, don't talk about it. When the time comes, it will naturally develop.

"By the way, in agriculture, high-yielding and improved varieties are fundamental. But agricultural tools such as waterwheels are also essential. There is still potential to be tapped in this area. ”

Cao Mengde nodded again and again: "What Mr. said is true." Little did he know that in the years since he left, the craftsmen had invented several tools that had a positive effect on farming. Plows, harrows, and so on. Speaking of this, Cao Mengde smiled: "I also invented a threshing machine." ”

"Oh?!"

Zhao Yu was curious.

"It's a machine of Konoha driven by a waterwheel. Cao Mengde explained in detail: "A log with many fine leaves inlaid on it. Push it with a waterwheel and turn it, hold the ears of wheat on it, and you will be able to twist the wheat grains down!"

Zhao Yu laughed. Although it is the most primitive threshing machine, if the craftsman can come up with these, as long as he makes a start, more convenient and powerful machinery will surely emerge in an endless stream in the future.

The Zhuxia people have always been wise and industrious. As long as there are conditions, what can't be invented?!

Cao Mengde left the next day, and Xi Zhi stayed for the time being.

He is not yet healed, so he can't work too hard. The environment of the annex was suitable for recuperation, so he was forcibly left behind by Cao Mengde.

Zhao Yu sent Cao Mengde away, and he felt a lot of feelings in his heart.

He himself was an introduction, bringing many wonderful seeds, which are now beginning to take root.

It is conceivable that the more traces Zhao Yu leaves in this era, the more drastic changes will occur on this planet, the civilization on this planet. And this is exactly what Zhao Yu wants to see.

After the cultural class of the disciples in the morning, when they were having lunch, Zhao Yu suddenly said to Xi Zhicai: "Mr. Zhicai's abdomen has a history of scriptures, and he has a furrow in his chest, and I also sigh to myself." I'm afraid I'm a little busy these days, dare to ask Mr. Zhicai to teach these disciples on my behalf?"

Xi Zhicai's face was much better than a day ago, the environment here was different after all, Yuan Qi was abundant, his breath was nourishing, and the whole person was much more relaxed, and he smiled when he heard this: "I want to do what I want." ”

So in the following period, Xi Zhicai took on the cultural course of teaching Cao Ang and other ten disciples.

With the wisdom of Xi Zhicai, it is very simple to teach these hairy children.

And Zhao Yu himself began to solve the many troubles that Cao Mengde threw at him.

Arrays and talismans are indispensable. And Xi Zhicai here, the pill to cure the disease, also cannot be delayed.

As for the array flag to be refined, it can be placed in the back, after all, there is no urgency.
