Li Shimin was considered to be the best at fighting among the kings since ancient times, and the reason why he was able to successfully become the emperor and kill Li Jiancheng was also related to his military ability. Therefore, in the military tent, anything that was unnecessary was very important to him.

Annoyingly, after hearing Li Chengqian's words, he stood up and asked, "What is this?"

"I heard from my brother that this is a necessary item for fighting, but my son is not very good at fighting. I hope my father can give me some advice." After Li Chengqian said this, Sun Dechao next to him began to explain it to Li Shimin.

The beauty of.

Things that were originally a mess became very clear after someone sorted them out, especially several dangerous places, which were explained very carefully. In Ye Tan's words, if Pang Juan had such a map,

Even Sun Bin can't trick him into it, and after knowing these things, he can also formulate relevant methods.

Li Shimin's eyes were as bright as searchlights. He didn't expect that he would find so many things here today. Moreover, if this thing really existed, it would be a very good thing. If he went to fight somewhere, he would no longer need to be a scout.

The kind of words in it seem to be like, after all, the commander-in-chief cannot just look at the terrain, and the land issue at the right time, place and people is very troublesome, because you don't know, so it is very troublesome.

After reading it, Li Shimin felt that he finally understood why Li Chengqian was able to protect his people so quickly last time. This was how he came up with this trick.

But Changsun Wuji on the other side said, "Your Highness, this is good, but the cost must be quite high. I'm afraid it won't be easy for the generals of the Tang Dynasty to use it."

He knew that Ye Tan couldn't let him get too proud, and what he said was right. What Li Shimin was most afraid of now was spending money. As long as he didn't need money or food, he could do anything.

Seeing Li Shimin's bad expression, Sun Dechao on the side explained, "Sir Shangshu said that this is not difficult as long as you master arithmetic. There is also some credit from the Ministry of Industry. As long as you cooperate sincerely,

It won’t waste a lot of money.”

"I will report the cost of these things tomorrow." Li Shimin didn't care about this. As long as he didn't spend too much, he didn't care.

Sun Dechao glanced at Li Chengqian, who bowed and said, "Father, I will help you."

After watching what he should see, Li Shimin went back, but he dragged Li Chengqian to see Empress Changsun.

Although it was already midnight, this was the first time such a scene occurred in the Manna Hall.

Empress Changsun glanced at Li Chengqian and ordered the people below to prepare meals. However, Li Shimin went out without eating.

The food came very quickly. Li Shimin might be really hungry, so it was all big fish and meat. As for the delicacies, Li Shimin couldn't afford them now, so he had to eat some big fish and meat first.

He sat there eating, while Li Chengqian stood there, not because he didn't want to eat, but because he wasn't hungry. Empress Changsun didn't invite him, but just sat aside to pick up food for Li Shimin.

Li Chengqian felt that such an appearance was inappropriate, so he took out a book from his arms and read it. The two huge arithmetic official scripts on it told others that this thing was not the Four Books and Five Classics. As a prince, it was useless to read so many so-called serious books.

Because as long as he wants those things, countless people will give them to him, so he starts to learn these partial skills. After learning them, he can be busy with these things before becoming the emperor. It is also a kind of comfort, otherwise he would spend every day

Thinking about how to be an emperor is very hard work.

Li Shimin didn't eat very fast, but he couldn't help but was really hungry, so he finished his meal quickly.

After removing the empty plates from the dining table and serving a pot of fragrant tea, Li Shimin took a few sips and looked up at his eldest son who was standing aside reading a book. He couldn't help but asked with satisfaction, "Cheng Qian, What book are you reading?”

Li Chengqian looked very charming while reading. He looked particularly handsome under the light. After hearing Li Shimin's words, he put down the book, handed it over and said, "Father, what I am reading is arithmetic."

Although I didn't understand, I still put the tea bowl in my hand aside, then took the book and opened it to read.

His face suddenly changed, because he found that he couldn't understand the content above. He knew the words naturally, but he really couldn't understand Arabic numerals, and mathematics is a very logical subject. He saw It took a while to understand and solve the first question, and it took a long time. He looked up at Li Chengqian who was looking at him with an expressionless face, and couldn't help but put the book on his face with a slight blush. The man on the table said, "Cheng Qian, how can you read these books?"

"Reporting to my father, I feel that the Four Books and Five Classics can be read casually, and there is no need to memorize them by rote. This seems to be more useful for the Tang Dynasty."

"What?" Li Shimin suddenly stood up, pointed at Li Chengqian with his book and said coldly, "You think the Four Books and Five Classics are useless, but this one is. Tell me, what's the use of this? It's just a clever trick."

"Father, my son is currently interning in the Sixth Department and has seen a lot of things. For example, the money and food of the Ministry of Household Affairs, the projects of the Ministry of Works, the rules of the Ministry of Rites and the life of the Ministry of Civil Affairs are all closely related to this." Li Chengqian was not impressed. I would be scared and explain it word for word.

"Oh? Are all the words of the sages wrong?" Li Shimin asked, putting the book on the table and asking.

Empress Changsun didn't take it seriously, she just looked down at the palace lanterns outside, as if she had a different feeling in her heart.

"Of course the words of the sages are not wrong, but it does not mean that they are necessarily comprehensive. I have read a lot of books recently and found that many places cannot be integrated with our Tang Dynasty. If this continues, we need to make progress and develop more Come with more things, otherwise, in the middle and late period of the Tang Dynasty, everyone will find that they are still the same as in the past, living in a dream or clinging to the clan system without changing it, then they will decline like the past dynasties, and the sons and ministers will not want to in this way."

Li Shimin was shocked by his words. Could it be that you, a boy, are more powerful than the emperors in the past dynasties? People didn't realize it.

However, what he didn't know was that people in the past had seen it, but no one dared to say it, because if they said it, they would offend too many people. There were too many people who lived by adhering to the laws of their ancestors. Because it doesn’t require too much brainpower, anyone who can read can do it.

"It seems that you have your own ideas. Come on, let's talk about it." Li Shimin was not a brainless person. Thinking of what he found in the Prince's Sixth Army Camp today, he decided to listen to Li Chengqian's ideas first.

"Father, I will give you a simple example. Our Tang Dynasty is definitely short of food now, and there are many reasons why there is not much food. I won't go into them one by one here. If there is a lack of food, the price of food will definitely be high. Yes, at this time, our court should find ways to lower the price of food. But how to lower the price and how much is appropriate? This may require a small official, because they can calculate. But next year, when the weather gets warmer There will definitely be a period of huge food production in the Tang Dynasty. Because they are afraid of hunger, everyone will definitely plant food crazily. By then, the food in the Tang Dynasty will definitely be inexhaustible, but if it cannot be eaten, the Tang Dynasty will After the people are full, they will definitely want to eat something else. If there is too much food, it will be worthless. After planting so much food, they will find that they are still not living well. At this time, most people The court of the Tang Dynasty should introduce a policy to purchase these grains, firstly to ensure that the court had enough grain, and secondly, to prevent the people from having a bad life because there was too much grain and they could not sell it for the price. And what is the price? How much it is needs to be grasped by the court, and I need to know this now. Otherwise, how can I go down below to see the officials' operations in the future? When the time comes, they will fool me, and I still don't know. What should I do? Then I can I’ve bullied a lot of people.”

When Li Chengqian's words were taken out individually, Li Shimin said he understood them, but now when they were put together, he found that he couldn't understand them.

Don’t understand? An emperor can’t hear his own son’s words. What kind of thing is this?

Of course, it doesn't matter if he doesn't understand. It's fine if Li Chengqian knows, because this is the category of political economics, and Ye Tan is willing to tell him these things.

"Just to adjust people's livelihood, is it inappropriate to ask the prince of the Tang Dynasty to learn such things?" Li Shimin doesn't understand, but that doesn't mean he can't speak. It has been like this since ancient times. Parents are always right, even if they are wrong.

You can find any random excuse to excuse it, as if everything you do is right under the love of your parents.

"My son is now the prince and a minister of the Tang Dynasty. There are many things that need to be learned now. Naturally, this is what we need to learn. The common people are the foundation of the Tang Dynasty and the foundation of all dynasties. They don't care, but I care." Li Chengqian's words made people happy.

Empress Changsun was very excited when she heard this. This child has really grown up and is simply too smart.

"It seems that you really want to do these things, so let's do this for the time being. By the way, besides the topographic map, tell me everything else Ye Tan gave you, so as not to be embarrassed.

." When he said this, he glanced at Queen Changsun.

"This, I can't explain at the moment." This sentence is definitely sincere. You suddenly asked me to say what I know. Isn't this nonsense?

"Then let's talk about ice cubes." Li Shimin also felt that this was inappropriate, so he chose a topic.

"This belongs to a unique academy in Songzhou called the Ye Family Academy, which is the predecessor of the current Fanlong Academy. They specialize in things like investigating objects, and these things are just superficial." Li Chengqian actually also

He wasn't very clear, but when Ye Tan told him these things, he was still shocked, simply extremely shocked. These things are simply treasures.

"Ye Family Academy, Fanlong Academy?" Li Shimin knew the latter, because Li Gang was deceived by Ye Tan, but he didn't expect that there was a Ye Family Academy. Thinking of this, he couldn't help but stand up and asked, "Could it be that

, does the development of Yejia Village have anything to do with this?"

"Yes, Father, my brother said before that although he played a big role in it, he is still one person after all, and no matter how big the role of one person is, it is not big, so he trained the people of Yejiacun

, and when he heard about the drought and insect plague, he planned to do another thing. If it succeeds, the people of Songzhou will no longer be barbarians." Li Chengqian thought of Ye Tan's ancient

Such a weird idea, I can't help but marvel at it.

"What's the matter?" Li Shimin asked in confusion. For Datang, disaster relief is disaster relief. Is there anything else? At a time like this, the biggest fear is not disaster relief, but the worry that someone will enrich themselves.

If that's the case.

"Relieve disasters through work, and provide disaster relief through literacy." When Li Chengqian said this, he couldn't help laughing.

Li Shimin didn't smile. He understood the first four words. After all, there are still such methods in many places. It's just that too many people find it troublesome and don't do it. The second one doesn't understand.

What do you mean? Do you mean you have to be literate to receive relief? If this is the case, the people of Songzhou will not starve to death.

"What's the meaning?"

Li Chengqian suppressed his smile and continued, "Father, what Ye Tan means is that if you want to eat, yes, you have to work. At the same time, if you want to eat, yes, you have to know how to read, and at least you have to use your

Write your name down, otherwise, you'll be hungry."

"How is this possible? Reading and literacy are so difficult. Isn't he afraid of getting into trouble if he does this?" Li Shimin said angrily. After all, studying has been a hard job since ancient times. Of course, it was for ordinary people.

"Brother said he's not afraid, because in front of an hungry stomach, no problem is a problem." Li Chengqian said in a low voice, which made Li Shimin stunned for a moment, and then he thought about when he went out to fight, when he was hungry, everything really didn't matter.

Get it done.

"It's just, Father, many state governments may not be able to provide relief for this disaster. If you go to other states and counties by then, I wonder if you can let some people go if you don't want to come back?" This sentence was what Ye Tan asked Li Chengqian to do.

I’m asking to help. After all, although the household registration system was not serious in the past, it doesn’t mean it didn’t exist.

"His ambitions are quite big. In years of disaster, officials at all levels are afraid that too many people will be under their control, which will make life difficult. But he is good. He is still worried about this. It is really not easy." Li Shimin said with a smile,

Neither agreed nor disagreed.

"Father, I wonder if you will stop me when the time comes?" Li Chengqian continued to ask, this matter is not a trivial matter.

"Let's take a look at his disaster relief ability first." Li Shimin didn't deny it, he just said this. Then looking at the joy on Li Chengqian's face, he suddenly asked, "How many benefits has Ye Tan given you?"

"It's just 10,000 sheep." Li Chengqian was also relaxed and said it casually. Li Shimin was stunned for a moment. The joy just now disappeared and he said angrily, "Ye Tan, he is really a stingy guy, so he gave it to me.

Five thousand?”
