"Liulang, what's wrong? Who dared to mess with our Tang Dynasty?" Cheng Huailiang asked the first question.

This is the main hall of the Qi Palace, and the cups and plates are in a mess. Half an hour ago, there was a lively banquet here to celebrate Li Yan's first child's full moon. However, with an accelerated battle report, Li Shimin and most civil and military ministers who came to attend the banquet had to go to the palace to discuss matters. The remaining guests were no longer interested, and it was not too early, so they said goodbye, leaving only young people such as Cheng Huailiang and Li Jingye.

"Things are not good. It's a war in Tubo!" Li Yan said while coming in from outside the door, and Li Ke was also with him. After Li Shimin and the civil and military ministers left just now, the younger generation wanted to know what happened, so they asked Li Yan and Li Ke to inquire, so it's easy to come back now.

"Tubo? Could it be that they held a grudge in their hearts because they started this war because they frowned?" Qin Huaiyu analyzed with a frown.

"Tubo children, if they had known this, they would have kept Songtsen Gampo to see if they had the courage to stroke my tiger beard from the Tang Dynasty!" Fang Yiai, who was tall and powerful, also jumped up and yelled. He learned a lot of military strategies with the Huli brothers and sisters, and now he is studying in the military academy, and he has long wanted to have a chance to show his strengths.

When he heard that it was a war that happened in Tubo, almost all the people on the scene reacted like Fang Yiai, clamoring to raise an army to destroy Tubo and then capture Songtsen Gampo alive!

"Liulang, the last battle in Songzhou should have hurt Tubo. It's just two years later, and they can't recover their vitality. How could they have the courage to fight with my Tang Dynasty?" Compared to the excitement of others, Li Jingye, the youngest, expressed his own opinion.

"The question of professionalism has come to light, and this time it may disappoint the brothers in the military academy." Li Yan said with a smile, "The key to the conflict between our Tang Dynasty and Tubo this time is because of something."

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

"Cement!" Li Yan gently spit out two words, and a few murderous intent flashed in his eyes.

"cement?"

When everyone present heard this answer, they were stunned. The quick-witted person immediately woke up and couldn't help but shout: "So that's it. There are so many cement factories in our Tang Dynasty, and as long as we pay a batch of patent fees, we can get the cement firing process. However, this has long been listed as one of the top secret technologies by our Tang Dynasty, and it was unexpectedly spread to Tubo!"

"The Tubo boy is so brave. He dares to steal the technology of our Tang Dynasty. All of our families have paid patent fees to have cement firing technology. But the Tubo people are better, and they are stolen and taken back to Tubo. This kind of practice is a corner of our families. We must not let them go softly!" Cheng Huailiang couldn't help it anymore and jumped up and shouted loudly.

"Cement is a country's important weapon. If the Tubo people were allowed to develop cement, if my Tang Dynasty wanted to attack Tubo in the future, I would probably face a series of extremely strong cement cities." Qin Huaiyu, who had always been calm, also spoke, his tone was full of murderous aura. It seemed that he was really angry with Tubo.

"Liulang, please tell us the information you have obtained in detail with our Tang Dynasty. How far has the situation in the two countries developed?" At this moment, Li Yong, who had not spoken, also asked. Seeing his firm look on his face, he obviously concluded that there must be a big battle between the Tang Dynasty and Tubo, and those who want to go to the battlefield naturally need to be prepared first.

"This happened two months ago. I hadn't returned to Chang'an at that time. After the last battle of Songzhou, our Tang Dynasty occupied a considerable territory on the Tubo Plateau. In order to adapt to the terrain of the Tubo Plateau, a strong city was built there, which is Tunfan City!" Li Yan said this, and a smile could not help but show a smile on his face. When the people around him heard the name Tunfan City, they all laughed, even as calm as Qin Huaiyu.

In the last battle of Songzhou, Li Shimin asked someone to build a stronghold on the occupied Tubo Plateau and named it Tunfan City. This name obviously disgusted the Tubo people, and the ambition of the Tang Dynasty could be seen from this name. After all, Li Shimin was very angry with Tubo at that time. If the other party had not occupied the advantage of the territory, he would have sent troops to destroy this growing powerful enemy.

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

Just two months ago, Tunfan City received information from the Tang Dynasty merchants. According to what they saw with their own eyes, the Tubo people actually began to build cement plants. Although the output is not high and the quality is not good, it is also cement after all.

After receiving this information, Tunfan City naturally attached great importance to it. After all, although cement plants are everywhere in the Tang Dynasty, they are one of the commodities listed by the imperial court as listed as strategic materials. Even selling them to the outside world is strictly controlled, let alone let Tubo establish a cement factory. As for the technical source of the cement burning of Tubo, there is no need to check it. There are so many cement factories in the Tang Dynasty, and the firing technology of cement has long been no secret. However, the Tang Dynasty is extremely powerful and has long been told that anyone who dares to burn cement without authorization will destroy it!

After receiving the news of Tubo firing cement, Tunfan City immediately sent people to investigate. The results soon obtained the exact news that the firing cement was not found in Tubo, but only two tribes closer to Tunfan City. One of these two tribes is called Tongyang and the other is called Pilian. They are both larger tribes in Tubo, and there are no less than 100,000 people together, and there are tens of thousands of people who can fight. It can be said that they are the two local emperors on the eastern border of Tubo.

Here I want to explain the composition of Tubo. The unified political situation of Tubo is different from the Tang Dynasty. In fact, it is composed of tribes. Among them, the heads of the tribe and some nobles formed the slave-owner class of Tubo. Most of the other people are slaves. In addition to slave owners and slaves, there are also a small number of civilians.

Although the tribes within Tubo usually obey the orders of the king Songtsen Gampo, if they conflict with the interests of their tribes, they will arouse resistance from these tribes. Moreover, the tribes are not peaceful, and wars often occur. This is similar to the grassland countries like the Western Turks. Although there is a nominal co-lord, each tribe has great freedom. Even if a tribe becomes strong, it may still defeat the tribes that control the throne.

The investigation of the frequent sacrificial city finally determined that in Tubo, only the two tribes, Tongyang and Viagra, disobeyed the orders of the Tang Dynasty, established cement factories among the tribes, and sold the fired cement to the outside to make profits.

As soon as the matter was confirmed, the Tang soldiers of the Swallowing Fan City did not hesitate at all. They immediately raised 10,000 troops and divided the troops into two groups to attack Tongyang and the two adjacent tribes. With lightning speed, they wiped out all the two major tribes in just three days, and captured tens of thousands of prisoners. Unfortunately, the leaders of the two tribes escaped from the chaos and rushed to the Tubo king Songtsen Gampo. However, due to the power of the Tang Dynasty, Songtsen Gampo did not dare to send troops.

He could not hear that Tubo did not send troops, and the city of Tunfan did not want to understand the matter so easily. Instead, he sent an envoy to meet Songzan Ganbu and sternly asked the other party to hand over the two culprits to the Tang Dynasty for handling, otherwise the Tang Dynasty would never give up!

Tubo was very angry about the unreasonable attitude of the defenders of the Tunfan City, and even some of them were clamoring to start a war with the Tang Dynasty. Unfortunately, Songtsen Gampo knew very clearly that with Tubo's current national strength, a national war broke out with the Tang Dynasty. It is estimated that a small Tunfan City alone would be enough for them to drink a pot.

However, although Songtsen Gampo did not dare to fight with the Tang Dynasty, he was unwilling to hand over the leaders of the two tribes. After all, no matter what, these two people were their own subordinates. If he, the king of the country, could not even protect his two subordinates, it would definitely hit his prestige greatly. If it was even more serious, it might also cause dissatisfaction with him in various tribes in the country, resulting in the impact of national government orders.

It is precisely because of this that when Songtsen Gampo faced the rushing steps of Tunfan City, he still gritted his teeth and refused to let go. He made up his mind not to hand over the lord. He also mobilized 100,000 heavy troops to surround Tunfan City, but did not make any attacks. Instead, he made a defensive gesture, obviously telling the Tang Dynasty that he did not intend to fight at all, and mobilized these troops just to protect himself.

Tunfan City was too unbearable to Songtsen Gampo's move, so it had to report it to the court. As a result, the war report happened to arrive at the banquet today, which disturbed all the Chou and the Chou Full Moon Wine.

"Happy, the defenders of Tunfan City are indeed brave. They actually destroyed the two large tribes of Tubo quietly, but Tubo didn't even dare to fight back. This is the mighty military power of my Tang Dynasty!" After hearing Li Yan's introduction, Li Yong was the first to slam the table and shout, and at the same time he picked up the wine pot and drank a few mouthfuls.

"Hehe, that's right, but cement is a powerful weapon of my Tang Dynasty. The border army has received an order long ago. As long as someone in the surrounding small country dares to burn it, they will immediately kill it with thunder. It is precisely because of this order that the defenders of Tunfan City would not be so brave!" Cheng Huailiang also drank a few cups, and then spoke. The other people in the hall praised Tunfan City. Such a method of doing things was indeed right. The ambitious name "Tunfan". (To be continued)
