Such a move immediately caused panic among the guards on duty outside the large barracks.

Originally, I had never seen any big people in my life, but suddenly I saw two legendary emperors near here, and I panicked all of a sudden, and my heart was pounding.

Suddenly, one of them walked towards him, and it felt like a mountain was pressing down on him.

Almost out of breath.

When the soldiers on duty saw that it was the empress of Ruan Guo, they hurriedly exchanged glances with their companions, and sent one person to the barracks to inform the soldiers, and the rest began to think about how to deal with it.

If His Majesty the Emperor of Cangguo himself could say that it would be okay to kneel on the ground and shout long live, but if it was the emperor of another country, if he knelt on the ground and saluted, it would be too embarrassing for the army of Cangguo.

Of course, this is all the idea of the guards on duty, and in fact it is all superfluous.

Because, Empress Ruan didn't care about these at all, and after approaching the barracks, she looked directly at the window, not caring at all about the stunned guards next to her.

This time, not only her personal maid, but even Yang Mu felt that something was wrong.

This scene makes people feel weird.

The dignified emperor of a country, standing by the window and watching the scene in the barracks, is it too unsightly and a loss of identity?

It so happened that at this time the lectures in the barracks also stopped.

Whether it was the lecturer who was teaching or the grassroots generals who were listening to the class, they all looked solemn, stood up and stood in a military posture, ready to welcome Yang Mu's arrival.

Yang Mu was quite helpless, and gave Empress Ruan Guo a look, and said, "Why don't you go in and have a look?" ”

Empress Ruan Guo still gave him a blank look, but her movements were not slow at all, and she entered through the main entrance.

Yang Mu followed suit.

The grassroots generals inside were both excited and nervous, they were all the first time to approach His Majesty the Emperor so closely, the fanatical worship psychology made everyone unable to control themselves, Rao was a man who was not timid in the bloody battle on the battlefield, and he was also trembling with excitement at this time.

After the salute, all the grassroots generals stood respectfully, thinking that they would be able to listen to the teachings when the emperor made his rounds.

Unexpectedly, Yang Mu waved his hand: "You go on, just listen to the class as usual, I and the empress just want to see how you attend the class." ”

After a little hesitation, all the grassroots generals, including the lecturers, were in place.

Yang Mu glanced at it, and according to the armbands on the uniforms of these grassroots generals, it can be seen that most of these people are centurions, and a few have three hundred generals and a thousand generals.

So, he made a gesture of please, stood side by side with the Empress Ruan, and listened to it from the side.

At first, the soldier was still a little nervous, beads of sweat appeared on his forehead, his face was red, and he didn't speak very neatly.

After Yang Mu gave him an affirmative look, the situation was slightly better, and after a short period of time for half a cup of tea, it became normal.

It turns out that the content of today's class is about the geographical convenience of marching and fighting.

"Fighting with troops is mainly a contest of soldiers and horses, grain and grass, and swords and arrows, so it is very important to choose favorable terrain at the battle site and make full use of the geographical advantages. Surrounded by mountains, valleys, water, and forests, you can get the convenience of water and grass, and it is easy to survive and retreat. With a mountain back, you can be a high-pressure enemy. It does not welcome the current, and can prevent the enemy from driving, poisoning and inconvenience in boat fighting. If it is unfavorable, it is not advisable to stay for a long time. It is necessary to choose sunny drying, so that the soldier does not get sick, reduce combat effectiveness, and so on. These favorable measures, which take advantage of favorable geographical advantages, are an important guarantee for winning the war. ”

"Before, we gave an example, which is called a half-crossing attack, that is, when the enemy crosses the river to fight, and some people have not crossed the river, and the entire army has not yet been reorganized, they will strike at it, so that the enemy will not be connected from head to end and the ranks will be confused."

"There are six kinds of terrain, such as passing, hanging, branching, passing, dangerous, and far. Wherever we can go and where the enemy can come, it is called "Tong," and in the "Tong" shaped area, we should first occupy the open and sunny high ground and keep the grain and grass supply lines unblocked, so that it will be advantageous for the enemy to fight. ”

"Any area where it is possible to advance and difficult to return is called "hanging", and in the hanging area, if the enemy is unprepared, we can suddenly attack and defeat them; If the enemy is prepared, we will not be able to win by attacking, and it will be difficult to return to the division, which will be disadvantageous. ”

"Any area where it is unfavorable for our army to attack and the enemy to attack is also called "branch"; In the "branch" area, although the enemy lures each other with advantage, we should not attack, but should lead the army to pretend to retreat, and induce the enemy to return to the division to counterattack halfway through the attack, so that it will be advantageous. ”

"In the "pass" shaped area, we should occupy the enemy first, and block the pass with heavy troops, so as to wait for the enemy's attack; If the enemy has already occupied the pass and is heavily defended, we should not attack; If the enemy does not defend the pass with heavy troops, then it is possible to attack. ”

"In the "dangerous" territory, if our army occupies the enemy before the enemy, it is necessary to control the open and sunny high ground in order to wait for the enemy to attack; If the enemy occupies it before us, we should withdraw with our troops and not attack it. ”

In a "far" area, the enemy and us are evenly matched, so it is not appropriate to challenge and reluctantly seek war. ”

"The above six points are the principle of using the terrain, and this is where the great responsibility of the general lies, and he must seriously investigate and study it."

The middle-aged lecturer said and said, and there was a lot of convenience, and it was getting better.

Yang Mu listened, and nodded his head, but at the same time, he felt very familiar, which book of knowledge on the art of war should have been copied by himself, but because it was too miscellaneous and too long, he almost forgot it.

He inadvertently glanced at Empress Ruan Guo and found that there was a different kind of look in her eyes, which she listened to with relish.

Until the lecturer finished speaking, Empress Ruan Guo was still immersed in thought, holding her chin with one hand and nodding her head constantly.

"Wonderful, really wonderful!"

Empress Ruan Guo stroked her palms and praised, nodded incessantly, and when she looked at the lecturer, she looked very appreciative and full of energy.

Being praised by the emperors of other countries, the lecturer was a little embarrassed, and hurriedly bowed slightly.

Empress Ruan's face calmed down slightly, and she looked at Yang Mu and said, "I'll ask him a few questions, don't you mind?" ”

Yang Mu pursed her lips, she really didn't know what to ask, seeing that she had never seen the world, she didn't want to say anything, so she said, "You say hello, I don't care." ”

Empress Ruan nodded, looked at the lecturer and said, "What you just said is the strategic strategy of the territory in the marching war, but I often think that in the war for many years, there will be victories and defeats, can you talk about the two sides of the war, how can they achieve victory?" ”

"This ......"

The soldier hesitated a little and bowed his waist, meaning that Yang Mu didn't open his mouth to let him say, he couldn't say it.
