Xu Qilin quickly turned his back and raised his chin at Princess Jinyang with a smile.

One was five years old and the other was six years old, and the two little girls were not heavy either. For the twelve-year-old man Xu Qilin, he gritted his teeth and tried hard. The small universe exploded, and he stood up with a hey voice.

With the princess on her back and the little girl in her arms, Xu Qilin felt less pressured.

"Ah, ah!" Xiao Zhao saw the three-dimensional map, opened his eyes wide and exclaimed.

Princess Jinyang lay on Xu Qilin's back, her dark eyes still blinking, and the sound of inhaling was right beside her ears. Xu Qilin could hear it sincerely.

Not only His Majesty Li Er and the two girls, Xu Hui was also shocked.

When it comes to flat maps, she naturally has seen them. It is too demanding to say that they are winding ghost drawing talismans. But compared with this clear three-dimensional map, well, it is really far behind, too far.

"That's Chang'an." Princess Jinyang stretched out her little hand and pointed, "It's so close to Mount Zhongnan!"

Xu Qilin pointed to the scale on the wooden frame and explained: "Your Highness, the maps are made according to scale. I took one inch and turned a hundred miles..."

His Majesty Li Er also noticed the details of the three-dimensional territory map, such as the scale on the wooden frame, and the orientations between east, west, south and north.

"Qi Lin has put his heart into it." His Majesty Li Er knew that the energy it takes to make such a map and the books it needs to read were not something that could be completed in a short time.

After pausing, His Majesty Li Er said again: "There are blurry places on this map, such as mountains, rivers, passes, roads, etc., which may not be very accurate, right?"

Xu Qilin hurriedly said, "Your Majesty clearly. When the people made this picture, they searched for historical records on the one hand, and collected suggestions on the other hand, but they were afraid that they were not detailed and untrue. Therefore, they had many knowledges and doubts, so they dared to compile them again."

His Majesty Li Er smiled and expressed his praise for Xu Qilin's serious attitude towards making the map. At the same time, he also agreed with the two methods of making the map mentioned by Xu Qilin.

Searching for historical records means looking up old pictures preserved by the central and local governments, so as to master first-hand information and accumulate rich geographical knowledge. This is the basis for mapping.

To collect public opinion, we are conducting extensive investigations and interviews, and those who can be asked about businessmen who travel around the world, as well as people from all over the world.

Compared with Xu Qilin's contact surface and ability, it will not be difficult if His Majesty Li Er wants to expand or improve the map.

Collect old pictures and books and order special people to organize the information; ask merchants, envoys from the four barbarians, and court officials who returned from the four barbarians.

As long as we follow these two principles and methods, with the power of the emperor and the power of the court, we can create a larger and more detailed map, isn’t it easier than Xu Qilin personally?

His Majesty Li Er wanted to praise him, but when he saw Xu Hui blinking at him, he remembered what he had promised. He stroked his beard and thought about it, His Majesty Li Er began to find fault.

"Qi Lin, I remember you once said that the model you made can help me plan and win a thousand miles." His Majesty Li Er pointed to the three-dimensional map and said, "But this is probably not useful, right?"

After saying that, His Majesty Li Er waved his hand at the palace servant next to him. The palace servant hurriedly bowed forward and hugged the little princess who was crawling on Xu Qilin's back like a monkey.

Xu Qilin was not panicked or defended, and smiled confidently and said, "Your Majesty, please see, there is a model made by the grass people here."

His Majesty Li Er looked in the direction of his finger and found that there were objects in all directions in one corner of the side hall, covered with linen.

Xu Qilin had a "number of gold" on his back, and his steps were light. He walked over with his younger sister in his arms, and reached out and slowly lifted the linen.

The divine light in His Majesty Li Er's eyes condensed, and he walked in a few steps. He arrived in front of the sand table and watched with great attention.

That's right, it's the sand table. It's a combat sand table in the Tuyuhun area created by Xu Qilin in a certain proportion.

At that time, Tuyuhun had already joined the Tang Dynasty and was a vassal state of the Tang Dynasty. Xu Qilin made Tuyuhun's sand table not to imply that the two countries would go to war, but to include part of Tubo on the sand table.

Just this year, the first war broke out between the Tang Dynasty and the Tubo generals, and the cause was that His Majesty Li Er refused Songtsen Gampo's proposal.

Although His Majesty Li Er knew about the Tubo place and the king of Tubo was called Songtsen Gampo, the Tang Dynasty court, including him, did not have enough and clear understanding of the situation in Tubo.

At that time, the Tang Dynasty and Turks and Tuyuhun had intermarried, but they refused Tubo because Tuyuhun interfered, which hit Songtsen Gampo's self-esteem.

Perhaps it can be said that Tang Tu's first war was Songtsen Gampo in order to get married and to make an excitement.

For Xu Qilin, this sand table mainly displays the pathways intuitively and is dangerous, so that the Tang army can make a leap in combat command.

As for Tubo, it was followed by the way. After the war broke out, His Majesty Li Er could respond faster, thus giving a higher evaluation of the sand table.

His Majesty Li Er looked at the three-dimensional model that marked roads, rivers, towns, and forests with different colors, and stroked his beards and sighed: "The ancient book records: Ma Yuan, a general of the Eastern Han Dynasty, "gathered rice into a valley and pointed to the situation," which made Emperor Guangwu suddenly feel that the enemy was in my eyes! This is the effect made by Qi Lin?"

Xu Qilin replied respectfully: "Go back to Your Majesty, Xiao He of the Western Han Dynasty collected maps of Qin to help Liu Bang seize the world. General Fubo Ma Yuan gathered rice into a valley to draw the situation and help Emperor Guangwu defeat Wei Xiang and pacify Longxi. Cao people envied the former philosopher, so they made this model to do their best for Your Majesty and the Tang Dynasty."

His Majesty Li Er slightly looked at his head without any concealment of appreciation and said warmly: "Qi Lin has such ambition, which is very good, and he is worthy of comfort. But this - how to use it?"

Xu Qilin reached out and pulled under the model. There was a drawer containing some small wooden men and small wooden signs.

"Please look at your Majesty." Xu Qilin cheered up and inserted a small wooden sign into a round hole on the head of a small wooden man. It was marked with a "10,000" sign, and then placed the "10,000" soldiers on the city model.

"Oh, the defenders in this city are 10,000." His Majesty Li Er said with a smile.

Xu Qilin took out another small wooden man, but he was riding a horse, and then put it on a road, pointing and saying, "There are ten thousand cavalrymen. The distance from here to that city can be calculated according to the scale and scale, so you can know how many days it will arrive; if it is an infantryman..."

His Majesty Li Er understood everything now and was deeply shocked by the effect of this sand table.
