Seeing that several of the most famous generals of Datang are basically here, although Li Anran still doesn't know where to use troops this time, he finally doesn't need to be as careful as he was at the beginning when it comes to his own safety.

After all, even if Li Shimin wants to kill himself who is extremely threatening and impossible to control, he will not pull so many henchmen to be backing up in the future. The only thing that is a little depressed is that in the middle of this room, which has obviously become a military aircraft deduction room, there is actually a sand table!!

"General Cheng, is this a sand table?" When inquiring about the history of the Tang Dynasty, Li Anran, who didn't care about this information search, pointed to the sand table with a lot of area and asked.

"Yes, Sha Table, why are the real people so surprised?" Cheng Yanjin, who was also a little confused for a while, replied.

"How can there be a sand table?" Li Anran, who always thought that this thing should have appeared in modern times, was dumbfounded.

"Why can't there be? It is all in the theater, in the military department, in the palace, and in the camp tents of the army, but ordinary people can't see it. Cheng Yanjin, who didn't understand why the other party would be so surprised by a small sand table, explained.

At this time, Li Jing also stepped forward and said: "Real person, this sand table was there in the Guangwu period of the Han Dynasty, and there are also relevant records in the "Later Han Shu Ma Yuan Biography", I don't know if there is anything wrong?" ”

"Uh......" Seeing the surprised looks in the eyes of the two famous generals of the Tang Dynasty, Li Anran also knew that his reaction just now was obviously a bit of a fuss, and he said with a smile at the moment: "There is also a sand table in the mortal march of the upper realm, but it is too relevant so I am surprised." ”

In the face of such an explanation. After Cheng Yanjin and Li Jing glanced at each other, their hearts moved together.

"Real person, I don't know what is the difference between all the sand tables in the upper realm?" Li Jing, who has been a general all his life, asked.

"There must be differences, but, Old General Li, where did the sand table in the Nether come from?" Li Anran, who knew that the other party would ask such a question, was organizing the language in his mind while using this topic to delay time.

This sand table is recorded to have come from the Eastern Han Dynasty, and it is said that Emperor Guangwu of the Han Dynasty was conquering the hustle and bustle of Longxi. He once summoned the famous general Ma Yuan to discuss the strategy of entering the army. And Ma Yuan is very familiar with the geography of Longxi. The strategy is deduced by using rice to form a model similar to the terrain of the field, which is the earliest sand table. The erudite Li Jing explained very easily.

"I'll it. Such an important thing as the sand table was actually available in the early years of the Eastern Han Dynasty. It's a shame that I didn't believe the plots in those online YY novels. Take out the big killer weapon like the sand table and show it off, otherwise this face will be lost at home. ”

Fortunately, I am glad to be glad to be glad. After Li Anran listened to Li Jing's professional explanation and looked at the sand table carefully, he found that there was indeed a lot of gap between the sand table and his own resemblance, all in all, it was too rough.

Seeing that he had found an entry point, Li Anran nodded pretending to be silent, and after quickly organizing the relevant language, he said: "I see, it seems that there are many things in common in the upper and lower realms. ”

"Real person, you are going to tell me what is the difference between the sand table in the upper realm!" As a general, even a brute general like Cheng Yanjin who "doesn't learn and has no skills" knows the true value of the sand table, and immediately asked.

"This ...... There are many differences. Pointing to the extremely rough sand table in front of him, Li Anran said: "In the mortal world of the upper realm, the most ordinary sand table is even more than this, how to say it, it should be more fine." ”

"More fine?" Cheng Yanjin and Li Jing, who didn't react to what they meant for a while, and several other famous generals who were originally deducing strategies in front of the sand table, but didn't find out that Li Anran came in because they were too concentrated, couldn't help but be a little dumbfounded.

"Yes, fine." Li Anran, who nodded, said: "I don't know where this sand table in front of the generals is located, but I know that this sand table is too crude, and the effect of using it for strategic deduction is not very good." ”

"By the way, General Li, if you can get it, can you tell me where the terrain in this sand table is? Of course, if it involves military aircraft, it is inconvenient to say that I have not mentioned it, so don't be embarrassed. ”

Just when Li Jing was a little hesitant whether to say it or not, he heard a rather majestic voice coming from the door: "Pharmacist, since the real person asked, you just say it's okay." ”

When everyone followed the sound in unison, they found that Li Shimin, who was dressed in civilian clothes, was walking in from the door.

Everyone in the room, including Li Anran, saluted at the same time: "See the Holy One." ”

The difference is only that Cheng Yanjin and Li Jing are courtesy, while Li Anran is just a simple Taoist chief salute.

"All Aiqing don't have to be polite, let's get up." Li Shimin waved his hand, with a warm and friendly expression.

It's a pity that among all the people present, Li Anran didn't take it seriously, and the others still did enough etiquette, and said in unison: "Thank you." ”

After the politeness of the crowd was finished, they gathered in front of the sand table under the leadership of Li Shimin.

"Isn't the real person trying to know the terrain of Lu Dao here, this is the Helan Mountains, this is Yin Mountain, this is Taiyuan, this is in the clouds, and this is the White Road." Li Shimin, who was standing in front of the sand table, directly took over the work of the commentator, pointed to the crude mounds, small ditches, and small pits in the sand table, and said very complacently.

"I see, I see, I ...... this" Looking at the almost similar shape of the area with a black line, Li Anran said perfunctorily, but what kind of broken sand table is this, it is not as good as the castle that children in later generations pile on the beach.

"Huh? Real person, isn't this sand table right? Li Shimin, who was showing off, suddenly stopped talking and asked after feeling someone's obviously not right look.

"It's not wrong, it's just ......" I really want to say that this sand table is not even as good as the children, but considering the identity of this person, Li Anran decided that it would be better to be tactful, after all, he will cooperate with Datang in the future.

"Just what? Real people, but it doesn't hurt to say it. Li Shimin, who had long known that the real protector of the country in front of him had a lot of good things, didn't care about the problem of face at all, and said very happily.

"Hehe......" Li Anran, who smiled before speaking, said: "Shengshang, General Cheng and General Li asked me before, what is the difference between the sand table used in the upper realm and the one used in the lower realm, I said before, the biggest difference is that the sand table here is too crude and too simple. ”

"Too crude, too simple?" Li Shimin, who had always thought that he was accustomed to the sand table in front of him, was a little confused for a while in the face of such an answer, just like Cheng Yanjin and Li Jing before.

"Let me explain." Seeing that these ancients were limited by their knowledge, and they couldn't understand what they meant for a while, Li Anran simply said openly: "Actually, what I want to mean is that although this sand table looks like it, it seems to be lacking in accuracy. ”

"The purpose of using the sand table during the march is to be able to see at a glance the form of both sides of the battlefield. It is also good to provide more specific, more vivid and more intuitive information for the generals. In order to facilitate the generals of an army to make operational plans and decisions based on this information. In the final analysis, this sand table is a tool for the deduction of marching and fighting. ”

"Of course, if this kind of sand table can be further improved, it can be used for strategic deployment and virtual operations even when it is not in war. By the way, the so-called virtual warfare is, to a certain extent, just on paper, but not with paper and words, but with a sand table that is very close to the real environment. ”

"In our upper realm, there is a game called military chess, which is different from Go, each chess piece represents a class of troops, and even some new games evolved according to military chess, which have made extremely detailed divisions in terms of arms alone, for example, there are sword soldiers, spear soldiers, shield knife soldiers and so on in the infantry."

"As for the sand table, you can also make a specific sand table according to different environments, climates, and even the division of the sky. If these pieces of refined troops can be integrated into this improved sand table, then, even in peacetime, these sand tables can be used to carry out some strategic virtual deductions, although it is a game, but the effect is ......"

Li Anran, who was talking violently, looked up, and found that a group of ancient people, including Li Shimin, looked at him as if he had seen a beautiful pervert, and he was immediately startled. (To be continued......)
