This house that was used as a study room, in addition to Amei, there were also Zhao Guang, Wang Xun and others, and even Guan Ji sat quietly on the other side, carving something on the bamboo slips with a knife and pen.

"Brother, your fireplace is really a good thing. Even in the middle of winter, this house can be as warm as spring, wonderful! ”

After Zhao Guang sat down, he approached the fireplace, stretched out his hand to bake the fire a few times, and praised.

"Don't talk about these useless things, do you understand what I taught you a few days ago?"

Feng Yong was not in the mood to listen to this sycophant, so he asked directly.

"Got it, got it!"

When Zhao Guang heard this, he hurriedly leaned over and sat not far in front of Feng Yong, "Is my brother going to teach a new class today?" ”

"If I don't talk about it today, Zishi has to be literate and listen to lectures, I'm afraid it's a little difficult. Today, I will discuss with you General Fubo's horse aid. If you have an idea, you can say it. ”

Since discovering that Zhao Guang was particularly interested in military affairs, Feng Yong selected some military theories summarized by later generations that were in line with the current situation, and took them out to listen to Zhao Guang and Wang Xun.

When it comes to marching and fighting, Feng Yong just shoots, at most plus dismantling and wiping guns, and when he arrives here, he can't even charge on horseback.

However, they are also people who have been sent to a certain base by the army for training, and they still know some basic military theories.

Moreover, every week, the army will have political and military lectures, and sometimes it will be required to write down the after-hearing feelings, and even test the backbone of the company at a specific time, so sometimes it is necessary to go to the company's reading room to check the information.

In addition, Feng Yong likes to read, so he soaks in the company's reading room on weekends. Therefore, he may not know much about the actual operation in the military, but when it comes to talking about it, as long as he does not meet professionals, he is not afraid.

He naturally understands more than others about the overall situation of the military, the relationship between politics and the military, the different composition of the armed forces in various historical periods, and the development and changes of the armed forces.

Pick and choose, and always pick out some knowledge that is useful to Zhao Guang and others.

At this time, Guan Ji would always stop what she was doing, and quietly watch Feng Tu turtle foaming at the mouth there, and sometimes when she heard a fresh and wonderful sleep, she would always smile with appreciation.

This is a woman with a strong temperament and extremely high martial arts, but with the meek temperament unique to women in this era - such a woman, not to mention that it cannot be found in future generations, even in today's world, I am afraid that there are few people.

Therefore, as soon as Feng Tujiao saw Guan Ji like this, he felt even more encouraged and spoke more energetically.

"Everyone knows that General Fubo helped Emperor Guangwu to revitalize the Han Dynasty, calm the hustle and bustle, pacify the Qiang chaos, and set Lingnan for his merits. But few people know that it has a great contribution, that is, piles of rice for mountains. ”

"Brother, isn't General Fubo's piling up rice into a mountain, isn't it exactly what he did when he pacified the hustle and bustle? How do you say that few people know about it? ”

Zhao Guang asked strangely.

Feng Yong smiled, "I'm talking about piling up rice for mountains, not about his peaceful hustle." The move of piling rice for the mountain is to create a precedent for another kind of map. ”

The so-called pile of rice is a mountain, referring to Liu Xiu's personal conquest of Kui, and the generals under his command think that the future is unclear, the outcome is uncertain, and it is not appropriate to go deep into the danger, Liu Xiu is also hesitant and difficult to make up his mind.

At this time, Ma Yuan was ordered to rush over, tried his best to persuade Liu Xiu to march, and ordered people to take rice, put it into valleys and ravines and other terrain features, and then pointed out the situation of the mountains and rivers, marking the way for the troops to advance and retreat.

This is the prototype of the original sand table.

This is a pioneering feat in the history of warfare and is of great significance.

"Amei, call two people and go and bring the sand table I made the day before yesterday."

Once again, thanks to the old professor who forced him to draw a map of Hanzhong for a semester, Feng Yong is still very familiar with the terrain of Hanzhong.

Although there may be changes in the topography of the mountains and rivers now and in the future, the general appearance is still similar, Feng Yong relied on his memory and spent several days holding sand and mud to pinch the general appearance of the surroundings centered on Nanzheng.

Anyway, it is not as accurate to the meter level as in later generations, this simple sand table, I am afraid that it is difficult to achieve the accuracy of 100 meters, but it is not to be used for any important purposes, even if there is a mistake, the meaning is on the line.

But even if it was like this, it was enough for Zhao Guang and Wang Xun to surprise Feng Yong into a celestial.

Even Guan Ji couldn't help but lean over, and when she saw the undulating mountains and winding rivers on the sand table, she couldn't help but point her finger at one of the places and asked in surprise, "Is this ...... Is this the camp? ”

"yes, that's where we are."

Feng Yongke didn't forget to teach, pointed to the sand table at the moment, and said: "Marching and fighting is nothing more than the right time and place, if you have such things, this place can be under control." ”

"Brother, brother, this ...... How is this done? ”

Zhao Guang woke up from his stunned state, and pounced all of a sudden, and the person almost pressed on the sand table, his eyes stared straight at the sand table, and his saliva was already flowing down.

"Baby, baby, this thing, don't change it for a thousand gold!"

Zhao Guang slipped away and sucked back the saliva that had almost dripped onto the sand table.

Paying off a thousand dollars? If someone really wants to buy it, Feng Yong is also willing to sell it for 100 gold per sand table - if Zhuge Old Demon doesn't mind.

Of course, if Feng Yong really dared to sell it, he was afraid that Zhuge Liang would dismantle him in eight pieces, and then hang him to the various gates of Jincheng to whip his corpse in public.

Proudly, Feng Tu Turtle looked at the appearance of several earth turtles and said, "How? Am I wrong? This pile of rice into a mountain is the greatest achievement of General Fubo when he was in peace, but the world is ignorant, how can they know the wonders? ”

"What my brother has learned is really unfathomable!"

Wang Xun looked at the sand table without blinking, and exclaimed, "This thing can be deduced from the military deeds of Fubo, if it is a march and a war, with this thing, even if you can't know yourself and your enemy, you can be regarded as invincible at least, right?" ”

"How can it be so simple?" Feng Yong waved his hand, "There is a premise for making this thing, that is, you must know the local mountains and rivers, which is not a simple matter. ”

"Where's the Tanma? If you send more detectives, even if you can't be as fine as your brother, even if you can get a rough appearance, I'm afraid it will be of great benefit. ”

Zhao Guang reacted very quickly and immediately asked.

Feng Yong nodded appreciatively, "Erlang does have understanding, so this march and battle must not be taken lightly." The more news you get from the enemy, the more chance you have of winning. This day and place are favorable, and they can be used by me, so that I can be called a general. ”

Feng Yong knew that he was at most a strong-mouthed king, and he didn't expect that he could really teach a famous general.

But teaching them theoretical things can at least allow Zhao Guang and Wang Xun to go to the battlefield in person in the future, and they can avoid some detours.

If it is said that it can make them feel the overall situation ignorantly, experience more in the future, and give birth to their own understanding of the concept, that is the best.

The sand table is currently one of the best tools to make people feel the entire battlefield and cultivate a sense of the overall situation.

What if?

If one of these people has this talent, then he also has a teaching grace, right?

Anyway, there is nothing to do in the winter, and idleness is idleness.
