Chang'an, Liangyi Hall.

Changsun Wuji, Fang Xuanling, Li Jing, Wei Zheng and others gathered together, and a picture was placed in the middle of them, with a few words written on it: Goguryeo border defense map.

The figure clearly indicates the number of troops and the transportation of food and supplies in each city on the border. Of course, there is also a geographical indication, where there are roads, how wide it can be, how big it can be, where there are rivers, where it can be forced to cross, where there is a bridge, and so on.

Changsun Wuji, Fang Xuanling and Wei Zheng were both civil officials. They did not show any abnormality when they saw the map. Only Li Jing's eyes immediately shone after seeing the map. If Li Shimin had not been standing on the side, he would have taken this picture as his own immediately.

"How about it, do you guys see anything?" Li Shimin sat far away, watching the few people circle around the map, took a leisurely picking up the cup, sucking a sip of tea, shook his head with emotion, and asked in a voice.

The tea he drank at this time was no longer the kind of cooking soup he had made, but the new tea that could be brewed with boiling water. The clear tea and sweet taste made this king who had been emperor for several years have the urge to smoke someone's board every time he tasted it.

"Your Majesty, where does this picture come from? Is it true?" Li Jing was all intent on the map on the desktop, and was asked back like a conditioned reflex when asked by the emperor.

This matter is just for Li Shimin. If Yang Guang was there, Li Jing would probably have to be beaten.

Fortunately, Li Shimin is not the kind of petty person. When he saw him asking, he casually said, "This picture is presented by Xiaoyaohou!"

"Xiaoyao Hou?" Li Jing was stunned for a moment: "Xiaoyao Hou who went to Goguryeo to obtain the remains of the soldiers of the previous dynasty who returned to his country?"

"It's this person!" Li Shimin nodded.

Li Jing's expression changed and he bowed to Li Shimin: "Your Majesty, if you are this person, you can quickly recruit this person back to Beijing!"

"Oh? Why? Is it fake to see this picture?" Li Shimin frowned slightly.

"Your Majesty, there is no possibility of falsehood in this picture." This time it was Fang Xuanling who spoke. After seeing Li Jing, the old man smiled faintly and said, "As for the reason, pharmacist, you should say it."

Li Shimin saw several important officials spreading their feelings there, and couldn't help but curl his lips and pretended to be angry: "You old guys are still keeping a secret here! Why don't you tell me quickly!"

"Your Majesty, you have led the troops for many years and you should have seen the tricks." Li Jing had already collected his energy from the map at this time. He looked at Li Shimin and said with a wry smile: "This picture does not tell how the data on it is obtained, but the method of making it alone is far more than that of the Tang Dynasty. So the map is so important!

"Well, it seems that your thoughts are the same as mine!" Li Shimin nodded, stood up from his seat, walked to the table where the map was placed, and pointed his fingers on it: "Contour lines and scales, these are things that have never appeared in my Tang Dynasty. I measured them according to the conversion method written above and found that each route drawn on it was actually drawn according to certain standards, and its length represents the distance."

"And the same is true for this contour line. It took me a long time to understand the meaning of these three words. It is precisely because of this that I discovered the mystery."

Li Jing sighed in agreement: "Your Majesty, it is precisely because of this that Xiaoyaohou has to return to Beijing quickly. If the Goguryeo people find out that Xiaoyaohou has brought such an important thing, they will definitely send someone to assassinate."

"No, someone impeached him some time ago in Goguryeo, fearing trouble. I guess he was just busy with this matter. Since there was nothing at that time, it means that Goguryeo didn't know what he did." Changsun Wuji shook his head and said.

"It's better to let Xiaoyaohou come back. Since Zhining's escort is enough, it's better to let Xiaoyaohou come back and explain the origin of this picture." Wei Zheng frowned his eyebrows and said thoughtfully: "If this method was created by Xiaoyaohou, at least you can be careful when calling him back."

Although Wei Zheng and Li Jing have different starting points in their view of the problem, their ultimate goal is the same.

Only Fang Xuanling watched coldly, and looked at Li Shimin who was a little excited and vaguely guessed something. However, due to the current situation, he did not say it directly, but just stood by and watched silently and stopped talking.

"Okay, let's call that boy Li Muyun back. I'm going to ask him some things!" Finally, Li Shimin figured it out, turned around and returned to the table, and said in a deep voice: "But you must strictly keep the secret about this map and must not leak it."

"I promise, I will follow the order." Changsun Wuji and others bowed together.

None of these people is stupid. Li Shimin did not let the map leak naturally, so they naturally would not ask too much.

Besides, the impact of the map is big or small. If you just take it to see it, this thing is actually useless.

But if a war really starts, it will be of great use. Whether it is to arrange troops or marching, it can be used almost everywhere.

Now Li Muyun presented Goguryeo's defense map to the Emperor of the Tang Dynasty, and even the above has been detailed to the location of each town. How many people are there in the town? If the war with Goguryeo will undoubtedly give the Tang Dynasty a great opportunity.

Who can play in the court is not a human being? It is natural that Li Shimin's purpose is not only Fang Xuanling. Even without this map, Changsun Wuji could guess that Li Shimin had the intention to destroy Goguryeo, let alone the map was placed in front of him.

The same is true for Li Jing. As an old ghost who has been fighting for wars all year round and pondered military tactics at home every day, if he didn't know that the Tang Dynasty was preparing to use military force against Goguryeo after seeing the map, he would have eaten in vain after only so many years.

...

However, Li Muyun, who was far away in Youzhou, did not know what was happening in Chang'an. Since Li Shimin wanted him to express his opinion, he would use practical actions to express his opinion. A map of Goguryeo is enough to prove his view of Goguryeo.

As for the remains of millions of soldiers..., in Li Muyun's opinion, there is no difference between the Qingshan Mountains, whether it is left on the border or escorting them back to Chang'an. As long as there are still people in the Tang Dynasty remember them, it is enough.

What really made him hesitate at the moment was actually the guy Quan Gai Suwen. Killing or not killing has become a big problem.
