Datang: Li Shimin begged me to rebel

"Let's not say whether this matter is true or not. Even if it is true, when the emperor of the Tang Dynasty will be replaced is up to our vassal states? Needless to say, the envoys needless to say, there is a relationship between me and Yipi Dulu Khan It is impossible to form an alliance." Zhenzhu Khan directly denied it.

"Zhenzhu Khan, please let me finish my sentence." The envoy said calmly.

"You speak."

"Datang is destined to expand! With the current structure of Datang, you should be very clear that they stopped at several passes in the West Kunlun Mountains. Why? It is because these places are strategically important places. As long as you control the These places mean that the west side of Datang is almost worry-free."

"The tens of thousands of troops stationed in these places are enough to curb the road to the west, unless it is detoured from the far north, but the ice and snow in the north, as well as the virgin forest, the journey of tens of thousands of miles, this is a road that is impossible for any tribe or army to gamble."

"Under such circumstances, Datang's ambition is obvious. Datang wants to completely eliminate all threats within its territory. Whether it is your Xue Yantuo, the nomads in the north, or Goguryeo and other countries, they are all in the pocket of Datang. "

"I'm not afraid to tell you Zhenzhu Khan, one of the purposes of my coming here is to contact Zhenzhu Khan, and the second purpose is to use Zhenzhu Khan's sphere of influence to contact Goguryeo, and we collectively attack Datang. "

"I don't know what Khan thinks, but why we nomads have always been able to live in this bitter cold place? That's all I said, Khan, please think about it." The envoy said directly gone.

After he left, Zhenzhu Khan fell into deep thought. His character is actually rather timid, otherwise, he would not have directly stabbed Jieli back then.

There is no doubt about the power of Tang Dynasty, and it is not the first time that Yipidulu has sent envoys, but what the other party said this time made Zhenzhu Khan have to think about this issue.

That is, if Datang really wants to wipe out all the threats around them, then Xue Yantuo must be their next target.

As for what the other party said about uniting with Goguryeo...it's impossible at all.

Because there are Khitan and Shiwei between them and Goguryeo.

Shi Wei's strength is stronger, but Shi Wei's overall is very backward, not comparable to Datang.And Khitan is even smaller, they will not unite with Xue Yantuo against Datang at all.

Because if they stand on Datang's side, there may be no accidents, but if they stand on their side, Datang will be gone, so how do you choose?

As long as the individual knows which one to choose.

What's more, here is so far away from Goguryeo, and even farther away from Ubidulu, which is tens of thousands of miles away. How can these countries cooperate?What if one country moves and the other doesn't?Wait to die.

This is simply unrealistic, especially since these countries are all vassal states of the Tang Dynasty. If someone repents halfway and directly informs, isn't that giving his head away?

Who wants to be this early bird?

"What do you guys think?" Zhenzhu raised her head and looked at the other people in the yurt.

When the envoy was here just now, Zhenzhu Khan also had several subordinate ministers here. They were all Zhenzhu Khan's confidantes, or generals directly belonging to Zhenzhu Khan's family.

"Khan, what the other party said may make sense, but in fact we have no choice." An old man in his fifties suddenly said.

"How to say?"

"Datang built about 7 new cities along the way from the Hetao area to Jiuyuan, Wuchuan, and Khitan. The distance between these cities does not exceed 400 miles. It is within the speed of cavalry support for a day, and Hundreds of miles behind Wuchuan City is Yanmen Pass."

"In these newly built cities, Datang has been emigrating around the border cities, and transporting supplies such as food, weapons and equipment. I'm afraid there are quite a lot of food and grass stored in these cities."

"The important thing is that the walls of these cities are built very fast, not to mention that they are not like some cities on our grasslands, but stone cities."

"This means that we have nothing to do with these cities. And Datang is also invincible." The old man said all the questions with a serious face.

"If we go to war with Datang, relying on these cities, Datang can advance and attack, retreat and defend, and it will not be a big problem to win us. Moreover, according to some information we have collected, Datang seems to be harvesting year after year, and there is no shortage of food."

"Khan, do you think that if Datang is not short of food, we can fight against us?"

"After all, the population of our Xue Yantuo is not too large, and our pasture is enough for us to graze. This is not the time for us to attack Datang, at least not when Datang is strong now and choose to be hostile to Datang." The old man said.

Zhenzhu Khan knew what the old man said about the population problem, or the khans of nomadic peoples in the past dynasties knew it.

The nomads living on this grassland since ancient times have learned how to use limited pastures to feed the largest population reasonably, and have summed up a rigorous and cruel sustainable development method.

Once the population increases, the livestock needed to feed the population will also increase, exceeding the limit of the grassland, they will launch an attack on the Central Plains Dynasty, and if they succeed, they can grab supplies and land to support their lives.

If it fails, then the defeat will kill a large number of people, thereby greatly reducing the number of people who need to be fed, and they can still continue to live.

If Zhenzhu Khan also traveled here, he would know that the Mongolian plateau north of the Central Plains, not counting the location of Shi and Khitan in the east, can maintain a population of no more than 300 million people.

The total number of livestock is maintained at most between 3000 million and 5000 million.If this number is exceeded, then the grasslands will be destroyed.

Of course, Zhenzhu Khan does not know the exact number now, he does not know how many herdsmen and livestock he has.

But they naturally have their way of observation, control the number of cattle, sheep and horses owned by ordinary herdsmen within a certain range, and minimize the number of nobles. As long as they know roughly how many tribes there are, they will probably know whether they can continue.

Once there is a situation where the livestock are starving to death, you must be vigilant.

Now, thanks to Xue Yantuo's surrender to Datang, Zhenzhu Khan also has some literate people under the name of Zhenzhu Khan. The population of their Xue Yantuo tribe is currently about 180 million.

When it is far from the limit, it is not beneficial to start a war with Datang at this time.
