Fang Xuanling did not disappoint everyone, as long as Lu Dongzan had an opportunistic mind, he fell into the trap.

Taiji Palace Imperial Study, Empress Changsun rarely listened to the politics here, for the specific arrangements and deployments of the war, there are many details that need to be negotiated, first of all, is how to make the encirclement of the army close before the Tubo army reacts, the left and right wings are okay to say, directly out of sight to line up the formation, just push forward.

However, the direction of the Tibetan army, that is, the back road after they stood under the city wall, can only be closed after they gather under the city, and they must be lined up in a tight formation, which takes time, once this encirclement is not tight, it may be highlighted by them, so it is necessary to drill in advance, pave some ridge roads that may reduce the speed of encirclement, and then calculate an accurate time, and finally, it is concluded that the two wings will take about half an hour, and they can advance to the designated position from outside the sight of the Tubo army, sealing both sides of the Tibetan army.

The back road is because it is necessary to hide to a position that the Tubo cavalry post cannot see, and then start to advance in formation when the Tubo cavalry is in a column, and the whole process takes an hour to ensure that the retreat of the Tubo army is completely sealed.

It was difficult to get the Tibetan cavalry to wait under the city for an hour.

"It's better to let the art troupe play music in the city, attract their attention, and explain to them that we need to have a certain ritual to make an important covenant, and after a few pieces of music are played, half an hour will almost pass."

After returning to Chang'an, with Du Ruhui and the eldest grandson Wuji to help, Sun Xiangfu finally didn't need to personally command everything, and his voice was barely able to speak, but he was busy with official business in the past two days, and the two little guys who had just reached the full moon were restless at night, Hongmei and Chuntao always pestered him to be coquettish, and he was a little haggard.

"Zhengming's proposal is feasible, but if you want the Tubo people to stay quietly under the city wall, I'm afraid you have to go out of the palace."

"You're out of the horse?" Several ministers looked at Empress Changsun suspiciously, and said in unison.

Empress Changsun nodded and said, "That's right, there is a palace and a hundred officials who appear in the city together, and accompany him to listen to the ritual music, which will make them more convinced, and accompany us to listen to the ritual music with peace of mind." ”

Sun Xiangfu nodded and said, "What Niangniang said is reasonable, however, it is always unsafe for you to appear in the city, you need to wear inner armor in your clothes, after the army is exposed, you have to go down the city wall immediately to hide, otherwise, if the Tubo people don't notice it, they are likely to shoot arrows at your side." ”

Hearing this, Empress Changsun glanced at him and said, "As far as you are most sorry for your life, Fang Xiang dared to go to negotiate with the Tubo army alone, and the palace was far away from the city, how could there be anything, this matter was decided." ”

Empress Changsun's words cannot be changed, and the criticized Sun Xiangfu had no choice but to shut up, and when the time comes, he can only ask Dugu Mou to prepare some soldiers with big shields to hide under the battlements.

At this time, Du Ruhui said, "For the sake of secrecy, starting from tonight, the gate of Chang'an will be closed, no one is allowed to enter and exit, and the person responsible for killing the enemy in the formation will go out of the city in the second half of the night, overnight, by their respective team leaders, training the team of the team, responsible for leading and guarding, tomorrow above the city, except for the musicians of the art troupe and the guards of the forbidden army guarding the city, no people shall go up the wall. ”

Military, it must be strict, there are Fang Xuanling and Du Ruhui planning, all kinds of similar small details, they have taken into account, even the burning time of the firewood and grass on the cart, as well as tomorrow's weather conditions and other factors, have been taken into account, as long as the army on the back road completes the array, the people on both wings of the formation begin to move forward, appear in the sight of the Tubo people, and set all the firewood and grass on the cart on fire, you can realize the encirclement of the Tubo army.

In addition to preparing a certain amount of firewood and grass for each car, a lot of oil is also prepared, or alcohol, plus it is constantly passed from the rear, it is no problem to burn all day, as long as the iron wheel of the board car is burned and cannot be pushed forward, they are framed to death within a certain range, they will be unable to fly, this kind of board car produced by Weinan car factory, but it is more than three meters long, after the flame burns up, there is more than one zhang high, there is no need to worry about any war horses dare to rush over, still far away, heat wave and crossbow arrows in the queue, A gravel attack can stop them, and behind the fierce train formation, the spear formation like a hedgehog can also pierce the whole body of the person who flies by.

After everything was arranged, Sun Xiangfu suddenly thought of a question, if the art troupe wants to go to the city wall to play music, wouldn't his wife Yu Xiuer also have to go to the city wall.

This time, Sun Xiangfu was not only despised by Empress Changsun, but also despised by his wife.

"Husband, it's true to be careful, but it's too timid······

The latter sentence 'will make people look down on', Yu Xiuer is really embarrassed to say it.

"The specific manifestation of being careful is to wear an extra layer of armor that can be protected! I don't care what others think, listen to my husband, tomorrow I must be the same as the soldier guarding the city, wearing a cotton armor uniform that can defend against arrows on the city wall, Wang Lin's guy will be under the city wall, in case he sees you, he will be angry······"

In the end, Sun Xiangfu still failed to persuade Yu Xiuer to wear cotton armor, and not only did she not wear it herself, but Sun Xiangfu was not allowed to wear it.

What Yu Xiu'er said is very reasonable, Sun Xiangfu has no way to refuse, but it is still necessary to wear a layer of gold silk soft armor in the underwear in winter, which is already Yu Xiu'er's biggest concession.

Before dawn, they will follow the large team of board cars on both sides of Yanping Gate, two kilometers away from the designated position, according to the previously lined up team, strictly arranged into a formation, the music on the head of the city is the signal for them to start, after starting to play, they maintain the formation, about half an hour, they will appear in the line of sight of the Tubo army, in order to prevent accidents, Qin Qiong, Li Junxian, Li Mengwei and other generals will each lead a thousand horsemen, and around the large team in three directions, kill all the Tubo sentinels, and capture people who should not appear in this area.

In fact, after more than a day of hurrying, the Tubo army had arrived less than forty miles away from Chang'an City, and Fang Xuanling specially sent someone to inform Lu Dongzan that Empress Changsun would lead a hundred officials to meet him at the head of Yanping Gate in Chang'an City, and of course, there was a complete set of procedures for signing the covenant.

As for what to play welcome music, courtesy music, ceremonial music, and then sign the covenant, after signing, there are also ceremonies such as farewell music, Lu Dongzan felt a little big, but seeing Tang Guo so solemn made his vigilance weaken a little.

Early in the morning, he called all the sergeants, fed the horses, ate, and set out. However, for the troops directly under his lineage, he also had another task to explain, that is, before the conclusion of the alliance, he took down the Empress Changsun and the hundred officials of the Li Tang court, he believed that only in this case, he could obtain the greatest benefits, empty Chang'an City at the minimum cost, and then force the Empress Changsun and the courtiers to sign a treaty of overlord that was most beneficial to their Tibet.

He even had the idea of bringing some important figures of the Li Tang royal family back to the Tubo Plateau as hostages and forcing the Tang Dynasty to carry out the overlord clauses he formulated, robbery, kidnapping, such criminal methods, the Tubo people in a semi-barbaric state, are born to do it!

In the state of full riding, the marching speed of the Tubo army was not slow, forty miles, fast horses were only a matter of more than an hour, and when they arrived at the city of Chang'an, the morning fog had not completely dissipated.

In the early winter season, this kind of fog is the best natural condition to hide the movement of the workers, peasants and soldiers, so the workers, peasants and soldiers who are responsible for blocking the back road of the Tubo army are moving more smoothly and faster than imagined.

Half an hour later, nearly 10,000 carts lined up one mile behind the Tibetan procession, behind the carts, there was a large shield array of spears, behind a large shield array of spears, a formation of bows and crossbows, then a chariot array, and some short-armed slingers, and then several columns of women carrying firewood or carrying stone baskets.

In the direction of the left and right flanks, such an array was also lined up early in the morning, and the three sides, a large army of almost 2.4 million people, plus a thick city wall as high as more than five zhang, framed more than 200,000 Tibetan cavalry, and then slowly narrowed the encirclement.

It was also on this morning that in a small village in Shuzhong, Shelong, who had been lying on the bed for nearly a month, was finally able to walk on the ground.

The river did not drown him, but just washed him to a beach dozens of miles away, after being rescued by the villagers, he went through a long period of coma, if it weren't for his clothes that were almost scraped into strips of rags, and a bit of the appearance of the new military uniform of the Tang Dynasty, the local people would definitely not have made great efforts to save him.

It's a pity that the Shu Road is too difficult to walk, otherwise, he would have asked these villagers to go to Yizhou City to report the news.

"Shelong thanks all the fathers and elders for saving their lives, and on the other day, there will be heavy gifts to thank each other, but at this time, there are still many important things that I need to do, so I will leave first."

The village is not big, there are only a dozen or twenty families, and it is not as rich as Guanzhong, but when they heard that Shelong was leaving, each of them gathered some food, and even an old man gave him his own firewood knife for self-defense, after all, there are many mountains and forests in Shuzhong, and there are many fierce beasts, so you have to take a guy when you go out.

Carrying the luggage and food that the villagers made up for him, he was very moved on the return journey, and he swore that his children and grandchildren would never allow them to rebel against the Tang Dynasty, and as for the other parts of Yunnan that killed him, he must help the Tang army to be wiped out and make it subordinate to Wanghua, and in the future, he will be like the Hanmin in Shuzhong, enthusiastic and hospitable, and helpful.
