"I also want to wait a little longer, when these policies of mine are mature, and when the power of the family is weakened by me a little more, but unfortunately time is running out, I want to see these things in my lifetime, the things I have built with my own hands." When Li Er said this, he couldn't help but sigh.

"The emperor doesn't have to sigh, it will be, these things, to put it mildly, still smashed to the word "money", as long as there is money, nothing can not be solved, what we have to do now is to let the people's pockets bulge, only when the people's pockets are bulging, our Datang treasury will be full. Zhang Nan said with a smile.

"You're right, as long as the people live and work in peace and contentment, why shouldn't my Datang be prosperous?" Li Er continued to look ahead and said.

"The emperor doesn't have to worry, as long as there is a thunderstorm and a hot air balloon, there are almost no countries in the surrounding area that are our opponents, and if the surrounding area is flattened, the emperor will have to take a long-term view. Zhang Nan said with a smile.

"Haha, with your words, I am relieved, if I can't do it, you must help Cheng Qian do it, so that even if I am under Jiuquan, I can see our Datang dragon flag floating in every corner of this world, and I will feel at ease." After Li Er finished speaking, he turned around and patted Zhang Nan on the shoulder.

Although Jindeman has been playing with the tablet, his ears have been listening to the conversation between Zhang Nan and Li Er, and seeing Li Er paying attention to Zhang Nan so much, Jindeman looked at his sister beside him again, and then began to think about it.

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

Faced with the sudden airborne Jindeman and Jin Shengman, Xihe and Xiruli could only look at the ball and sigh.

When he flew to the destination, Zhang Nan didn't bother much, set up a hot air balloon around the city, and took a clear picture of the area around the city where Quangai Suwen stayed with a flat plate, and Zhang Nan returned in 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, what do you want so much sand for? It's such an adult, why do you still want to play with pee. Cheng Yanjin poked his big head and looked at Zhang Nan fiddling with the sand with his hand and asked.

Hearing Cheng Biting Jin say this, Jindeman and Jin Shengman, who were standing on the sidelines and watching, both covered their mouths and laughed.

Zhang Nan's face immediately darkened after hearing this, and said: "Why is it urine and mud, this sand table is sand table, can it be done without sand?" As he spoke, Zhang Nan put the city model that was replaced from the system on a pile of sand.

Then he carefully placed the position of the trees and grass according to the photos, and even the height of Zhang Nan was as realistic as possible.

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

"Come, the emperor will see how the sand table made by the ministers is, is it exactly the same as the surrounding city where Quangai 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 to use this thing?" "It's the first time Li Er has used this thing, and he used to just write and draw on the map, and with this three-dimensional thing, Li Er's brain couldn't turn around for a while.

"Huh? Well, it's easy. As he spoke, Zhang Nan took out two more teams of soldiers of different colors, ten of which were placed in the city and five outside the city.

"You understand this emperor, a small soldier is 10,000 people, now the emperor you are the attacker, Brother Cheng, you are the defender, you each say your own strategic ideas and intentions, and then reduce the number of troops according to the guess, and finally determine the victory standard of this war. Of course, the defender doesn't know the trap the attacker lays, and the attacker doesn't know the defender's escape route, all of which have to be taken into account. ”

Zhang Nan roughly said how to deduce the deduction, in fact, Zhang Nan didn't understand how to use this thing, after all, he was not a professional, but Zhang Nan believed that Li Er and Cheng Yanjin were both professional, and this kind of thing must be self-taught.

Sure enough, Zhang Nan's guess was right, just ten minutes later, the two battle-hardened generals were familiar with the gameplay of the sand table, and even formulated some simple rules to control the intelligence acquisition of the two sides.

But after deducing more than a dozen times, Cheng Biting Jin didn't even make a breakthrough, it's not that Cheng Biting Jin is too incompetent, it can only be said that Li Er is too cunning, and Li Er still has a strange soldier in his hands, that is, the cadets of the military academy, as long as Cheng Biting Jin wants to escape, Comrade Li Er's hot air balloon and the air strike force of the thunder will be waiting on the way to Cheng Bitingjin's retreat.

"If you don't come, you won't come, it's not fair at all, what's the strength of being bombed when you go out of the city." Cheng Yanjin said with a sad face, although it is a deduction of the battle situation, but it fails every time, and no one can stand it.

"Haha, Zhijie, I only know Qingquan's sentence now, what does it mean to be beaten if you fall behind. Hahaha. Li Er seemed very happy, after all, the result of every deduction was the same, and Quan Gai Suwen didn't even have a chance to escape.

"Your Majesty, this thing is good, when we go back, we must get one in the military academy, so that Senior Brother Yao's combat case explanation course is much more convenient, and it looks more intuitive." Cheng bites the golden road.

"If you want to get it, you can't help but get it at the military academy, and you have to get 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, and this is still a small-scale use, if it is a large-scale war, it will be more interesting, the overall situation is in the eyes, no matter who the opponent is, there will only be a fiasco." Li Er said with a smile.

"Qingquan, this time you have come up with something unique, and it is so useful, I don't know what to reward you, this official position can not be promoted again, you are promoted again, this big ship brings back crops, but it is not promoted, or I will give you a princess." Before Li Er's words fell, Zhang Nan had not yet spoken, but he heard a snap not far away.

Everyone followed the prestige, only to find that Jin Shengman's water cup fell to the ground, and Jin Shengman saw that everyone was looking at her, and immediately blushed with shame, and then ran out with his face covered.

The few people in the room looked at each other.

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

"Cheongsen, this princess of Silla won't take a fancy to you, right?" Cheng Yanjin said, then patted Zhang Nan's shoulder and said.

"Hmph, even if she wants to marry, it will be ranked behind Lizhi." Li Er snorted twice and said.

"Where is this, be serious, your majesty, this is a war." Zhang Nan said speechlessly.
