"Liulang, what's wrong, which one of you dares to provoke our Datang without opening your eyes?" Cheng Huailiang was the first to ask.

This is the main hall of the Qi Palace, the palace is a mess of cups and plates, half an hour ago, there is still a lively banquet held here, in order to celebrate the full moon of Li Su's first child, but with an urgent war report, Li Shimin and most of the civil and military ministers who came to the banquet had to enter the palace to discuss matters, and the rest of the guests were not interested, and the time was not early, so they also said goodbye, only Cheng Huailiang, Li Jingye These young people remained.

"Things are not good, it's a war on the Tibetan side!" Li Su came in from outside the door and said, and Li Ke came with him. After Li Shimin and the Minister of Civil and Military Affairs left just now, the younger generation of them wanted to know what was going on, so they asked Li Su and Li Ke to inquire, so that they could come back now.

"Tibet? Could it be that it was because they couldn't get married last time, so they held a grudge and provoked this war? Qin Huaiyu frowned and analyzed.

"Tubo children, if they had known that this was the case, they should have left that Songtsan Gampo behind in the first place, and see if they still had the courage to pick up my Tang Dynasty's tiger whiskers!" The tall Fang Yiai also jumped up and shouted. He learned a lot of tactics from the Huli sisters and brothers, and now he is studying in the military academy, and he has long been eager to have a chance to show his strengths.

As soon as they heard that it was a battle on the Tibetan side, almost all the people in the field reacted the same as Fang Yiai's reaction, clamoring to raise troops to destroy Tubo, and then capture Songtsen Gampo alive!

"Liulang, it is said that the last battle of Songzhou should have already hurt Tubo, it has only been two years, it is impossible for them to recover their vitality, how can they have such courage to start a war with my Datang?" Compared with the excitement of others, the youngest Li Jingye put forward his own opinions.

"The question of dedication is to the point, and this time I am afraid that I will disappoint the brothers of the military academy." Li Su showed a smile and said, "The key reason why our Datang and Tubo conflicts broke out this time is because of one thing. ”

"Oh. What is it? Li Jingye immediately asked, and the others were also very surprised, because they really couldn't imagine what was it that made Tubo not hesitate to start a war with the Tang Dynasty?

"Cement!" Li Su gently spit out two words, and a few traces of murderous aura flashed in his eyes.

"Cement?"

Hear this answer. Everyone present was stunned. The person with a quick brain reaction immediately woke up and couldn't help shouting: "I see, we have so many cement factories in Datang, and as long as you pay a batch of patent fees, you can get the firing process of cement, but after all, this has long been listed as one of the top secret technologies by our Datang, but I didn't expect it to be transmitted to Tubo!" ”

"The Tubo boy is so bold that he dares to steal my Datang technology, and we all have to pay the patent fee to have the firing technology of cement. But the Tubo people are good, they directly steal it and take it back to Tubo, this practice is a corner of our family, and we must not let them go softly! This time, Cheng Huailiang couldn't hold back any longer, jumped up and shouted.

"Cement is the most important weapon of the country, if the Tubo people are allowed to develop cement. In the future, if my Tang Dynasty wants to attack Tubo again, I am afraid that I will have to face one after another extremely solid cement cities. Qin Huaiyu, who has always been calm, also spoke, his tone was also full of murderous energy, it seems that he is also really angry with Tubo.

"Liulang, tell us in detail about the information you have gotten and our Datang, where is the situation between the two countries developing now?" At this moment, Li Yong, who had not spoken, also asked. Looking at his resolute look, he obviously concluded that there must be a big battle between the Tang Dynasty and Tubo, and those of them who want to go to the battlefield must naturally prepare first.

"It happened two months ago. At that time, I had not yet returned to Chang'an, after the last battle of Songzhou, our Tang Dynasty occupied a large territory on the Tubo Plateau, and in order to adapt to the topography of the Tubo Plateau, we built a strong city there, which is the city of Tubo! When Li Su said this, he couldn't help but show a smile on his face, and the people around him all laughed when they heard the name of Swallowing City, even if they were as calm as Qin Huaiyu.

In the last battle of Songzhou, Li Shimin asked people to build a stronghold on the occupied Tubo Plateau, and named it Tunbo City, this name is obviously disgusting to the Tubo people, and from this name you can see the ambition of the Tang Dynasty, after all, Li Shimin was very angry with Tubo at that time, if it wasn't for the other party's geographical advantage, he would have sent troops to destroy this growing strong enemy.

After the establishment of the city of Tunbo, because of Songtsen Gampo's attitude of admitting his mistakes was very good, so Li Shimin was more satisfied, so the trade between the Tang Dynasty and Tubo was restored, and the city of Tunbo was the most important pass on the border between the Tang Dynasty and Tubo, so it became more and more prosperous, and even the Tang Dynasty in addition to the 20,000 troops stationed in the city, also sent many officials to facilitate the management of the merchants in the city.

And just two months ago, the city of Tunbo received information from the merchants of the Tang Dynasty one after another, according to what they saw with their own eyes, the Tubo people actually began to build cement factories, although the output is not high, and the quality is not good, but after all, it is also cement.

After receiving this information, Tunbo City naturally attaches great importance to it, after all, although cement factories are everywhere in Datang, they are one of the commodities listed in the strategic materials by the imperial court, and even the sale to the outside world is strictly controlled, not to mention letting Tubo build a cement factory, as for the technical source of Tubo firing cement, there is no need to check at all, there are so many cement factories in Datang, and the firing technology of cement has long been no secret, but Datang's national strength is extremely strong, and it has long been ordered to all countries, who dares to burn cement without authorization, it will be destroyed!

After receiving the news of Tubo burning cement, Tunbo City immediately sent people to investigate, and soon got the exact news that the act of burning cement is not in the whole country of Tubo, but only two tribes close to Tunbo City, these two tribes are called Tongyang, and the other is called adjacent, both of which are relatively large tribes in Tubo, adding up to no less than 100,000 people, and there are tens of thousands of people who can fight, which can be said to be the two emperors of the eastern border of Tubo.

Here I want to explain the composition of Tubo, Tubo is different from the unified political situation of the Tang Dynasty, Tubo is actually composed of tribes, among which the head of the tribe and some nobles constitute the slave owner class of Tubo, and most of the other subjects are slaves, in addition to slave owners and slaves, there are a small number of civilians.

Although the tribes in Tibet usually obey the orders of the lord Songtsen Gampo, but if they conflict with the interests of their tribes, it will also provoke the resistance of these tribes, and the tribes are not peaceful with each other, and there are often wars, which is similar to the steppe countries like the Western Turks, although there is a co-lord in name, but each tribe has great freedom, and even if a tribe becomes strong, it may also fight the tribe that controls the position of the lord.

The investigation of the city of Tubo finally determined that in the country of Tubo, only the two tribes of Tongyang and Adjacent Disobeyed the orders of the Tang Dynasty, established cement factories in the tribes, and sold the fired cement to the outside world to make a profit.

As soon as the matter was confirmed, the Tang soldiers of Tunbo City did not hesitate at all, and immediately raised 10,000 troops, divided their troops into two ways to attack Tongyang and the adjacent two tribes, and with lightning speed, it took only three days to wipe out the two large tribes, and at the same time captured tens of thousands, but unfortunately, the leaders of the two tribes escaped in the chaos, and to the Tubo lord Songtsen Gampo, but because of the Tang Dynasty's military might, Songtsan Gampo did not dare to send troops.

I couldn't hear that Tubo would not send troops, but Tunbo City didn't want to understand this matter so easily, but instead sent a messenger to meet Songtsan Gampo, and sternly asked the other party to hand over the two culprits to Datang to deal with, otherwise Datang would never give up!

For the unforgiving attitude of the defenders of Tubo City, Tubo is all very angry, and even some of the brains are clamoring for war with the Tang Dynasty, but unfortunately Songtsan Gampo knows very clearly that with Tubo's current national strength, it is said that a national war broke out with the Tang Dynasty, and it is estimated that just a small Tubo City is enough for them to drink a pot.

However, although Songtsen Gampo did not dare to fight with the Tang Dynasty, he was not willing to hand over the leaders of the two tribes, after all, no matter how these two people were also his subordinates, if he, the lord of the country, could not even keep two subordinates, it would definitely greatly hit his prestige, and even if it was more serious, it might also cause dissatisfaction among various tribes in the country against him, resulting in the impact of national decrees.

It is precisely because of this that Songtsen Gampo still gritted his teeth and did not let go when facing the pressure of Tunbo City step by step, and made up his mind not to hand over people, and also mobilized 100,000 heavy troops to surround Tunbo City, but did not make any attack, but made a defensive posture, obviously telling Datang that he did not plan to fight at all, and mobilized these horses just to protect himself.

For Songtsen Gampo's move, the city of Tunbo had no choice but to report to the imperial court, but the battle report happened to arrive at today's banquet, and all the ugly full moon wine was disturbed.

"Happy, the defenders of Swallowing Bo City really have the courage to wipe out the two big tribes of Tubo without making a sound, but Tubo doesn't even dare to fight back, this is the heyday of my Tang Dynasty!" After listening to Li Su's introduction, Li Yong was the first to slap the table and shout, and at the same time picked up the wine jug and poured a few sips.

"Hehe, that's right, but cement is the heavy weapon of my Tang Dynasty, the border army has already received an order, as long as someone in the surrounding small countries dares to burn, they will immediately be killed by thunder, and it is precisely because of this order that the defenders of Swallowing Bo City will not be so bold!" Cheng Huailiang also drank a few glasses, and then said, and the other people in the palace also praised Tunbo City, and they really did the right thing to do with the ambitious name of 'Swallowing Bun'.
