"I also want to wait a little longer, wait until my policies are mature, and when the power of the aristocratic families is weakened by me, it's a pity that I can't wait. I want to see these things in my lifetime, and what I have built with my own hands." Li Er couldn't help but sigh when he said this.

"The emperor doesn't have to sigh, it will definitely happen. After all, these things have been smashed to the word "money". As long as you have money, nothing can be solved. What we have to do now is to make the people's pockets bulge. Only when the people's pockets bulge can the treasury of our Tang Dynasty be full." Zhang Nan said with a smile.

"You are right. As long as the people live and work in peace and contentment, why worry about my Tang Dynasty not growing?" Li Er continued to look ahead and said.

"Your Majesty, don't worry. As long as there are thunder and hot air balloons, there are almost no countries around us that are our opponents. If you have flattened the surrounding area, your eyes will be long-term. With me, I guarantee that you can capture all the territory without saying that you can capture at least half of it." Zhang Nan said with a smile.

"Haha, I will be relieved with you. If I can't do it, you must help Chengqian do this. In this way, even if I am in the nine springs, I can see the dragon flag of our Tang Dynasty floating in every corner of the world, and I will feel at ease." After Li Er said that, he turned around and patted Zhang Nan's shoulder.

Although Jin Deman was playing with tablets, his ears kept listening to the conversation between Zhang Nan and Li Er. Seeing Li Er respect Zhang Nan so much, Jin Deman looked at his sister next to him, and then began to think about it.

The speed of the hot air balloon is much faster than that of the carriage. Zhang Nan flew to the designated position in two days. Of course, Zhang Nan also lowered the hot air balloon and rested in the front line for a night.

Facing Jindeman and Jin Shengman who suddenly arrived, Xihe and Xi Ruli could only look at the ball and sigh.

When he flew to the destination, Zhang Nan was not worried. He carried a hot air balloon around the city and took a flatbed to take a photo of the city where Quan Gai Suwen was staying. Zhang Nan returned with the hot air balloon.

When he returned to the palace, the first thing Zhang Nan did was to ask for a pile of sand.

"Qingquan, why do you want so much sand to do? Such an adult, why do you still want to play with peeing mud?" Cheng Yaojin poked his big head and looked at Zhang Nan fiddling with the sand with his hands and asked.

Hearing Cheng Yaojin say this, Jin Deman and Jin Shengman, who were standing by and watching, both covered their mouths and laughed.

After hearing this, Zhang Nan's face turned dark and said, "Why is it just peeing mud? This sand table is a sand table, can it be okay if you don't have sand?" As he said that, Zhang Nan locked the city model replaced from the system onto a pile of sand.

Then he carefully arranged the positions of trees and grass according to the photos, and even Zhang Nan strived to be realistic.

After fiddling for a long time, Zhang Nan finally got the sand table.

"Come on, the emperor, see how the sand table I made is like. Is it exactly the same as the surroundings of the city where Quan Gai Suwen stayed?" Zhang Nan said.

Li Er looked at it for a long time before pinching his chin and said, "It can't be said to be exactly the same, but it's almost the same. How should I use this thing?" This was the first time Li Er used this thing. He used this map and used this three-dimensional thing. Li Er's mind was still unable to turn around.

"Ah? This is simple." As he said that, Zhang Nan took out two teams of soldiers of different colors, ten of them placed in the city and five outside the city.

"Your Majesty, you understand. One small soldier is 10,000 people. Now you are the attacking party. Brother Cheng, you come to the defending party. You each express your strategic ideas and intentions, and then reduce the number of personnel based on the guesswork, and finally determine the victory standard of the war. Of course, the defending party does not know the attacking party's traps, and the attacking party does not know the defense's escape route. All of these must be considered."

Zhang Nan roughly said how to deduce the deduction. In fact, Zhang Nan doesn’t understand how to use this thing. After all, he is not professional, but Zhang Nan believes that Li Er and Cheng Yaojin are both professional, and this kind of thing must be learned without a teacher.

Sure enough, the guess with Zhang Nan was good. After only a dozen minutes, the two generals who had experienced many battles became familiar with the way of playing the sand table, and even formulated some simple rules to control the intelligence acquisition of both parties.

However, after more than a dozen deductions, Cheng Yaojin failed to break through once. This is not because Cheng Yaojin is too incompetent. It can only be said that Li Er is too cunning. Li Er has a surprise weapon in his hand, that is, the students of the military academy. As long as Cheng Yaojin wants to escape, Comrade Li Er's hot air balloon and the aerial strike force of the sky-burning thunder will definitely be waiting on Cheng Yaojin's way back.

"It's not fair to come, but I won't come anymore. What's the point of being hit by the bomb when I leave the city?" Cheng Yaojin said with a sad face. Although it was a deduction of the situation, every time it failed, no one could stand it.

"Haha, Zhijie, I only know what Qingquan's sentence means, if you fall behind, you will be beaten. Hahahaha." Li Er seemed very happy. After all, the result of each deduction was the same. Quan Gai Suwen didn't even have a chance to escape.

"Your Majesty, this thing is great. When we go back, we must also get this thing in the military academy. This will make it much more convenient for Brother Yao's battle examples and it looks more intuitive." Cheng Yaojin said.

"If you want to do it, you can't help but do it. I have to do it. I also need to make one in my imperial study. This thing is really useful. With the judgment of the terrain, all kinds of things can be taken into account. Moreover, this is a small-scale purpose. This would be even more interesting if it was a large-scale war. The overall situation is in my eyes. No matter who the opponent is, they will only have to lose a crushing defeat." Li Er said with a smile.

"Qingquan, this time you took out another unique thing, and it was so useful. I don't know what to reward you. This official position cannot be promoted. If you are promoted again, the big ship brings back the crops, but there is no promotion. Otherwise, I will give you a princess." Before Li Er finished speaking, Zhang Nan heard a snap not far away before he could speak.

Everyone looked in the sound and found that Jin Saoman's water cup fell to the ground. When Jin Saoman saw everyone looking at her, he blushed in shame and ran out with his face covering.

The few people in the room were left looking at each other.

"What's going on?" Zhang Nan looked strange.

"Qingquan, this Silla princess is not interested in you, right?" Cheng Yaojin said, then patted Zhang Nan on the shoulder and said.

"Hmph, even if she wants to marry, she has to be behind Li Qi." Li Er said with a humming voice.

"What are you talking about? Be serious, yourselves, this is a war." Zhang Nan said speechlessly.
