After Mangbuzhi attacked the Tang Dynasty and returned from defeat, he didn't dare to hide anything, and honestly told Qinling and Zanpo in detail about the defeat.

Zanpo couldn't believe it when he heard it, of course, he couldn't help but scold Mangbu with his head and face.

Qin Ling was very calm, and he didn't blame Mang Buzhi after hearing this, but only said one sentence: "This Lu Xiaoxian is not simple, you are not unjustly defeated!" ”

Qinling is Zanpo's elder brother, and Zanpo can be called Qinling's second brother, but Mangbuzhi is very afraid of his father, and he never dares to call Qinling his father, so he can only call him official.

At this moment, Mang Buzhi also made great determination, so he made this request with trembling.

As soon as Zanpo heard this, he didn't fight anywhere, glared and reprimanded: "A thousand Tibetan elite cavalry were wiped out by the whole army of 800 united soldiers, you are still ashamed that you are not enough, and you want to invite him to dinner, are you dizzy?" ”

Mangbuzhi bowed his head.

Qin Ling was noncommittal, and his mind was still recalling the words that Lu Xiaoxian had said to himself just now.

After pondering for a moment, Qin Ling squinted his eyes and nodded at Mangbuzhi: "Go!" Don't let people think that we Tubo people don't count! ”

Mang Buzhi didn't expect Qin Ling to agree so easily, his face showed joy, and he saluted Qin Ling respectfully: "Thank you!" ”

"Second brother! How do you ......" Qin Ling's answer was also unexpected, he wanted to dissuade Qin Ling, but he didn't know what to say.

Qin Ling glanced at him and praised it: "On the battlefield, it is true that Lu Xiaoxian and Mang Buzhi are enemies, but now that he has come to Fu Qi City as an envoy of the Great Zhou, Mang Buzhi invited him to drink as a friend, why not?" Don't be so petty! ”

Qin Ling said this, and Zanpo could only shut up.

Qin Ling instructed Mang Buzhi again: "Since you are inviting friends to drink, you must serve the best food in Tubo and the best barley wine, don't let people look down on you, understand?" ”

"Don't worry, I will definitely entertain Mr. Lu well!" Mang Buzhi nodded.

After Mang Buzhi left, Zanpo whispered to Qinling and asked, "Second brother! What did that kid say to you just now? ”

Qin Ling glanced at Zanpo: "You don't need to ask about this!" ”

"But ......"

Qin Ling's face sank: "There is nothing, when you should know, you will naturally know!" ”

With that, Qin Ling turned around and left, leaving Zanpo alone in the room in a daze.

……

Coming out of the handsome mansion in Qinling, the hatred water wiped a handful of sweat from his forehead, and said with palpitations: "Master Lu, you are too bold, if you annoy Da Yan, maybe you won't even be able to save your head!" ”

Lu Xiaoxian said nonchalantly: "With Mr. Qiu here, you will definitely not let Da Xuan make such a low-level mistake!" ”

Hatred Water was suddenly speechless.

Under the guidance of Hate Water, Lu Xiaoxian and Guo Zhen took a big turn in Fuqi City. Compared to the towns of the Tang Dynasty, Fu Qi City was simply too small, and it only took them about half an hour to complete the turn.

On the way to send Lu Xiaoxian back to the post house, Hatred Shui said proudly: "I don't know if Lu Gongzi has found out, under the governance of Da Lun, these Tuyuhun people live very happily, and in their hearts, they have more recognition of Tubo than Datang!" ”

Lu Xiaoxian knew very well in his heart that what he hated about the water was the truth, and the triangular relationship between Tuyuhun and the Tang Dynasty and Tubo would never be clear.

Between the Tang Dynasty and the countries of the Western Regions, there was a long and narrow traffic artery called the Hexi Corridor. Starting from Chang'an to the northwest, passing through the Hexi Corridor, out of Yumen Pass, you can reach the Western Regions; Then through the Western Regions, you can reach the Nine Kingdoms of Zhaowu, and even as far as the Great Food Country. The Tuyuhun Khanate was located on the southern side of the Hexi Corridor and held the choke point of the Silk Road. If the bilateral relations between Tuyuhun and the Tang Dynasty were good, it would be possible to ensure the safety and smooth flow of this trade lifeline.

However, it is a pity that the relationship between Tuyuhun and Datang has not been very friendly since Taizong. Despite Emperor Taizong's efforts to establish good-neighborly and friendly relations with Tuyuhun, Tuyuhun repeatedly entered the western corridor of the Kou River, seriously threatening the security of the Tang Dynasty's borders and the Silk Road.

Tuyuhun adopted the practice of serving the yang and violating the yin, often sending tribute on the surface, but behind the scenes, he frequently invaded the northwest border of the Tang Dynasty, and successively plundered Lanzhou, Shanzhou, Kuozhou and other places.

In May of the eighth year of Zhenguan, Tuyuhun repeated his old trick again, sending envoys to pay tribute, and at the same time marching into Shanzhou to plunder. Emperor Taizong finally couldn't bear it anymore and sent an envoy to rebuke Murong Fuyun, the king of Tuyuhun, and ordered him to meet him in person in Chang'an.

Murong Fuyun lied about his illness and refused to enter the court, and at the same time asked for his son to marry the princess of the Tang Dynasty.

Tuyuhun's approach seems to be quite contradictory and unreasonable. In fact, it is not difficult to understand that they did this, but on the one hand, they wanted to loot more wealth and make some profits, and on the other hand, they did not want to completely break with the Tang Dynasty, for fear that the Tang Dynasty would make a big move, so they would repeatedly play this kind of trick of being a robber and flattering an eye.

Tuyuhun thinks he is clever, but he is actually playing with fire.

And those who play with fire will burn themselves.

This is a truth that is not easy to see.

Emperor Taizong gave a very clear answer to Tuyuhun's marriage proposal: if you want to marry a princess of the Tang Dynasty, you can, but Murong Fuyun, the king of Tuyuhun, must go to Chang'an to marry in person.

Murong Fuyun once again became a turtle with a shrunken head, not only did he not enter the court, but he also joined the army again, and even detained the Tang Dynasty envoy who sent Tuyuhun.

It's madness.

Emperor Taizong tolerated it again and again, and sent ten groups of envoys in a row to negotiate with Tuyuhun, but to no avail, Murong Fuyun turned a deaf ear.

Emperor Taizong's patience is limited, in June of the eighth year of Zhenguan, Tian Khan finally made a move, ordered Li Jing to be the supreme commander of the expeditionary force, Li Daozong and Hou Junji as the deputy commanders, and governed the Tang Army and the Turkic, Tiele, Qibi and other cavalry units, forming six major corps, with the momentum of thunder, launched a large-scale war against the unruly Tuyuhun.

Tuyuhun territory is vast and dangerous, horses travel thousands of miles a day, there are cities that do not guard, live with water and grass, habitually use the tactics of "mice and cats", and the dynasties of the Central Plains are around. Because of this, no matter whether it is won or lost, it has not hurt the vitality for hundreds of years. But this time, Tuyuhun met Li Jing, the most bullish military salute in the Tang Dynasty.

Li Jing is worthy of being a famous general through the ages, and he defeated the Tuyuhun army as soon as he made a move.

Tuyuhun was defeated and repeated, repeating the trick of "mice playing cats", and Emperor Taizong ordered the main force of the Tang army to search for Fu Yun. The Tang army marched out of Qinghai Lake on multiple routes, crossed 600 miles of quicksand, marched thousands of miles, chased to the end, killed Murong Fuyun, and won a complete victory in the battle of Tuyuhun.
