Li Shimin listened to Chen Fei's analogy, and this was simply shuddering. If Chang'an, the capital of the Tang Dynasty, falls, and the Li Tang royal family and all the ministers are martyred, I am afraid that the disaster for the Tang Dynasty will be devastating. Because once the capital falls, the royal family and ministers are killed, even if they are all captured, then I am afraid that the country will also create a state of power vacuum. This is very dangerous, especially now when the Tang Dynasty is still unstable, the generals who have military power in those places, who knows what they will think at this time? If the central government of Datang can maintain its strength all the time, then the place will naturally have no ideas, and can only accept its fate. However, once Chang'an fell, all the central officials were killed, and the world once again lost its unified order. At that time, the local army governors and marching commanders who have not yet been relieved of military power will probably have the idea of fighting for world domination again.

At that time, I am afraid that the world will be divided again. As for that time, Datang probably didn't exist anymore. As for the Li Tang clan that was exiled outside, I am afraid that it is impossible to have the capital to order those local warlords to make them loyal to them. The result of this is the demise of the Tang Dynasty, and there is no other possibility. Of course, Li Shimin knew about this situation, so he was immediately surprised.

"You're not alarmist, are you? How can anyone in my Datang have the strength to capture Chang'an? I have tens of thousands of troops in Chang'an, and even if someone wants to rebel, it can't be that we don't know anything! Li Shimin asked.

And Chen Fei immediately said: "Your Majesty, the current crisis in my Datang is outside but not inside. Your Majesty, if the Turks knew that my Tang Dynasty had changed its rights now, would they take the opportunity to come over and rob it? ”

"Turks?" Li Shimin was already panicking.

Only then did Li Shimin realize that would the Turks take the opportunity to come over and rob while the fire was fired? During this time, everyone set the target on the crown prince Li Jiancheng, but now they didn't expect that the Turks would take the opportunity to intervene? And if the Turks came, how could they resist?

"Probably not, right? My Datang and the Turks have formed an alliance! Li Shimin asked.

And Chen Fei immediately said: "Prince, this time and that time." Allow Xu Chen to say something unpleasant, back then, the Turks supported me in the Tang Dynasty, and that was in the hope that the more chaotic my land of China was, the better. And to support Datang back then, it was so that the land of China could not be unified and could be twisted into a rope. And the experience of the former Sui also let the Turks know that once the land of China is unified, the strength of the Turks will not be our opponent of a unified China at all. Therefore, they tried in every possible way to prevent our Tang Dynasty from unifying the land of China. ”

"And when Liu Heimin rebelled, didn't he also have the support of the Turks? Because at that time, my Datang had already swept the world, so of course the Turks were unwilling. However, Liu Heimin was not the prince's opponent, and after being destroyed, the Turks' plan failed. But the Turks will not stop there, so they will definitely want to prevent the unification of our land of China again, I am afraid that this time they will not support others, I am afraid that they will personally go out to prevent my Tang Dynasty from unifying the country. ”

"And the best way to obstruct it is to destroy my Datang Center. Once Chang'an of the Tang Dynasty is captured, and the emperor, the crown prince and all the ministers are martyred, the ambitions of the local princes will breed, and they will continue to fight for hegemony in the world. Even if you take a step back, even if you force me to move the capital of Datang, but once the capital is moved, the prestige of my Datang will plummet, and I am afraid that I will not be able to command the world. Chen Fei said.

Even if Li Shimin is a hero, he was also made into a cold sweat by Chen Fei's analysis. This is not impossible, but very possible. Of course, Li Shimin knew that the Turks were uneasy and kind to support Datang back then, but the strength of Datang was weak back then, so he could only accept the support of the Turks, and he knew that it was a bitter fruit and had to swallow it. But now that Datang has survived the most difficult period of time, it seems that it is about to dominate the world, so things will be different. At this time, once the Tang Dynasty dominates the world, it is destined to turn against the Turks. In the past, his strength was insufficient, so he naturally had to pretend to be a grandson. But now that he has become an equal existence to you, and even stronger than you, why should he be the emperor himself! I'm afraid that even Li Shimin knows that once the world is dominated, the civil and military officials and people of the Tang Dynasty will never allow the Tang Dynasty to be the emperor.

But the Turks also understand this, once the Tang Dynasty dominates the world, it will be equivalent to losing the interests of the past for the Turks. At that time, the benefits that could have been obtained in the past will disappear completely, and the Tang Dynasty will turn against the Turks, which the Turks do not want to see. And the Turks wished that the Central Plains would be as chaotic as possible, and then they would be able to profit from the chaos. This situation is similar to that of the warlords of the Republic of China in later generations, and foreigners do not want China to be unified, but hope that the more chaotic the better. As long as the land of China is more chaotic, it will also be safe for foreign countries.

Although the Turks and the later Westerners were not of the same race, they were politically interconnected. A unified China is too much of a threat to foreign nationalities, and of course they cannot allow the reunification of the land of China. Of course, they will find a way to stop it, so it is inevitable that the Turks will also go out in person, taking advantage of the transfer of power in Datang at this time, and quickly catch Datang off guard. If the central government of Datang can be completely destroyed, then the local warlords of Datang will once again set off the idea of fighting for hegemony. At that time, the Turks will also play something again to suppress this, win over that, and then get a lot of benefits. This kind of gameplay is the same as the later foreigners' gameplay in China. Chen Fei, who had studied historical strategy in the army, could easily see what tricks the Turks were playing.

"Go and call all the prince's subordinates, and the lonely king will summon everyone. It's a big deal, and it looks like we have to be prepared! Li Shimin said.

During this time, no one expected the Turks to come. During this time, everyone was immersed in the joy of the success of the Xuanwumen Change, but now there has been a biggest crisis since the founding of the Tang Dynasty, which has to be said to be very dangerous. Once it can't survive this crisis, the Tang Dynasty will probably collapse, and the land of China may once again return to the situation of troubled times, which Li Shimin cannot tolerate. This is also something that all central officials cannot tolerate, because they cannot let their boiled ducks fly, and the glory and wealth that they see are about to be lost will be lost, and no one will be willing to do this.
