"Prince, tell me your opinion." Seeing that after Pei Lin happened in the political hall, he fell into a dead silence where no one spoke, so Li Yuan simply named him.

Regarding the matter of Tubo, in fact, Li Jiancheng knew that his father was optimistic, but he himself was quite entangled, on the one hand, it was the national righteousness, and on the other hand, it was the life and death of the Li dynasty, which made him really unable to decide.

From his personal point of view, he tends to have a non-aligned attitude, advocating simply giving up Jingxiang, going to Yizhou to seek development, closing the four stops, turning it into an iron bucket, and then making a comeback and dubbing the victory with the Sui Dynasty.

It's just that Li Jiancheng also knew that the Li Tang Dynasty couldn't make his own decisions and couldn't decide by himself, so when he saw the letter from Tubo Langri Zampu, he kept pretending to ponder, not because he didn't want to say it, but actually because he didn't want to quarrel with his father and second brother. Now that my father has been named, naturally I can't pretend to be stupid anymore.

He sighed secretly, got up and saluted: "Enlighten the father, the sons tend to Liu Xiangguo's proposition, and must not lose the national righteousness. ”

"Brother Huang's words are wrong." Li Shimin also stood up, saluted his father, then looked at Li Jiancheng, and said solemnly: "After more than ten years of turmoil, many powerful old forces have been wiped out, and the unifier has at least a few hundred years of national fortune, as long as my Tang Dynasty seizes the world, who dares to say that we collude with Tibet?" After nearly 100 years of accumulation, the Sui Dynasty became history and was gradually forgotten by the world. At that time, the history books will say that Yang Dong colluded with the Turks, Tuyuhun, Goguryeo, Silla, and Baekje, and they will also say that Yang Dong colluded with the countries of the Western Regions, and the slave soldiers under Yang Dong are the best evidence. If it is my Tang Dynasty who fails, does the imperial brother think that Yang Tong will put the name of benevolence and righteousness on the head of our Li family? ”

Li Shimin looked around and continued: "As for the problem of Tibet, it is actually very easy to solve... Didn't Langri Zampu ask to marry my Tang princess? We'll just say yes. With this layer of in-law relationship. It is the alliance between the Tang Dynasty and Tubo that is the son-in-law, and the son-in-law helps his father-in-law to retreat from the enemy, which is natural and natural. As long as they join forces to defeat the Sui Dynasty, the future history books will only desperately praise it, and will only say that this covenant will be a good story of Weng and his son-in-law working together to retreat from the strong enemy. There will be absolutely no gossip, unless the person who speaks is dead. After such a long time, who still knows what is happening today? ”

Li Jiancheng shook his head and said, "Isn't it just a matter of becoming a king and losing?" I know. But the second brother overestimated the strength of Tubo. ”

Li Shimin was stunned and arched his hand: "I would like to hear it in detail." ”

Li Jiancheng said: "When the policy of moving the capital to Shu and conquering the south was formulated, I paid a lot of attention to the various countries and ministries in the southwest. As far as I know, Tubo is a country with enemies on all sides, due north is the Sui Dynasty, east is Bailanqiang, Duomi, Jialiang three parts, the northeast is Tuyuhun, the south is Niboro, the southwest is the daughter country, the west is Zhangxiong, the northwest is the big and small Bolu, except for the Sui Dynasty did not have a formal conflict with Tubo, the above countries and tribes were all offended by Langri Zampu, otherwise, how could they go all the way to Luoyang to ask Yang Dong for help? How could he bow down to Yang Tong? The strength of the Tibetan army is only more than 100,000 people, not only to defend against so many enemies, but also to prevent the restoration of many tribes such as Subi, vassal state, and Pengyu. Lang Ri Zampu in such a situation, how many soldiers does the second brother think he can send? Yang Tong even had the Eastern/Turkic Turks with millions of string control men torn apart, so what could the poorly equipped Tubo soldiers do? ”

Li Shimin argued: "The road to hegemony is like sailing against the current, either advancing or retreating. Now there are no decent forces in the country, Lin Shihong and Meng Haigong are almost finished, since Tubo can stand up enemies on all sides without dying, it can be seen that their army is not bad, maybe they are all elite divisions, if they are equipped with our equipment, their combat power will be doubled. Since Langri Zampu himself sent it to the door, if we can't grasp it, should we be killed? ”

Li Jiancheng snorted coldly and said: "Tubo is a nomadic country, not much different from the Turks, not to mention that the weapons and equipment are not compared with the Sui Dynasty, but worse than the Turks, Tuyuhun, and the Western Regions. At most, it is just to show off its power in the vast and sparsely populated West Sea. Langri Zampu himself seems to understand the gap between Tubo and the Central Plains, so it is written in black and white that he will not want an inch of land in the Central Plains, and his meaning is even more obvious, it is nothing more than to use the battle of the Sui and Tang Dynasties to make profits from it, just loot and leave, and then leave behind a tragic image of 'white bones exposed in the wild, thousands of miles without rooster crowing'. And then what? Yang Tong naturally took a bloody revenge. ”

Tubo was founded on a vast and sparsely populated plateau, and if the Sui army went to retaliate, Langri Zampu would have a big deal to roll up his tent and leave, and gain a foothold in another place. What should I do with Datang? And how to face the angry Sui army? ”

Speaking of this, Li Jiancheng sighed and said: "Langri Zampu is interested in the wealth of Hehuang and Guanzhong, and the advanced skills and advanced civilization of the Central Plains Dynasty, and he is not really allied with us. In addition, the strength of Tubo is just like that, it can't help us at all, but it will anger Yang Tong. Why should we give up our righteousness to form an alliance with someone who is difficult to do? And if the righteousness is in hand, as long as we work hard, we can make the people of Yizhou return to their hearts, if there is no righteousness, the result is a failure, once the people hear about the Tubo poison Hehuang, they will only feel cold and cold to my Datang, and it is impossible to support my Datang and Sui to fight. Therefore, there is no need for us to go hungry and make an alliance with Tibet. ”

Li Shimin was silent when he heard this, Tubo really looked like he was going to die, and he really had to think about it.

The conversation between their brothers also made Li Yuan's face hot and hot, and his earnest heart was cold. This Tubo feeling is a deception, and he gets rid of the benefits, and Li Tang is responsible for the notoriety. And it is really humiliating to announce it as good news......

In fact, he did not take the so-called 'great righteousness' to heart, he knew that benevolence and righteousness were just a coat of the ruler, and interests were the foundation of a country. However, after the two brothers said this, he began to hesitate on the issue of Tibet.

On the one hand, the Sui Dynasty was an indestructible divine sword, which was originally hidden in the sheath, but with Li Mi being annihilated by the Sui Dynasty, this divine sword against the Li Tang Dynasty had already begun to come out of its sheath, and the sharp blade of the sword made his heart cold, and he woke up from nightmares from time to time. Li Tang was isolated and helpless in the country, and the situation was precarious, so Li Yuan agreed with Li Shimin's theory of opportunity, hoping to attract foreign aid, and Li Shimin had a sentence that deeply moved him, that is, "Since Tubo can erect enemies on all sides without dying, it can be seen that their army is not bad, maybe they are all elite divisions, if they are equipped with our equipment, their combat power will be doubled." ”

But on the other hand, the crown prince Li Jiancheng is also very right, the Tibetans and the Turks are the same, they will not occupy the Central Plains to establish a country, loot the population, property and all kinds of books will be withdrawn to the plateau, at most can only harm the Hehuang area, is a temporary disaster of the Sui Dynasty, it is impossible to destroy the vast Sui Dynasty. When Tubo is withdrawn, the Tang Dynasty will definitely become the first target of Yang Tong's revenge, the Sui army will have the same hatred of the enemy, and more combat power will erupt, how should the Tang Dynasty face the crazy counterattack of the Sui army? A series of failures have left a very deep and heavy shadow in Li Yuan's heart, making Li Yuan afraid of Yang Tong in his bones.

For a time, Li Yuan was in an extremely contradictory dilemma......

Outside the door of the "Holy ......", a solemn-faced eunuch hurriedly broke in.

Li Yuan was furious: "Why are you so alarmed? ”

The eunuch saluted nervously and said, "Qiqi Sheng, something happened in Shangyong County, Fangling County. ”

"What?"

Li Yuan was taken aback, immediately forgot the annoyance in his heart, and hurriedly asked, "What happened?" ”

"Many of the private tribes of the Guanlong nobles have been reversed."

The eunuch's words were like a thunderbolt on a sunny day, which exploded in everyone's ears, and Li Yuanden was stunned, and his mind was blank.

I'm really afraid of something.

"Is the news true?" Li Shimin reacted and asked loudly and urgently.

"This is Fang Ling's urgent report." The eunuch submitted an urgent report.

Li Shimin snatched it, quickly looked at it, and said in a deep voice: "It's really the opposite." ”
