When Lu Dongzan's war horse rushed into the city, he felt abnormal, how could it be empty and there were no guards in such an important strategic place of the Tang Army? The fire ox was still wreaking havoc on the buildings in the city, but not a single figure appeared in the original barren houses, and after a while, he was rewarded by his subordinates, yes, it was an empty city.

"No, could it be that Zampu's army has already broken through the ice wall?" Lu Dongzan was puzzled, and he was not slow to order the soldiers to clean up all the living creatures in the city and guard the city gate, just half an hour, his subordinate Tubo soldiers took control of the entire Guancheng, but unfortunately, this did not bring joy to Lu Dongzan, he saw the billowing smoke from the direction of the camp, and the Tubo soldiers who fled back from scattered had announced to him that their camp had been breached, and their last food and grass supplies fell into the hands of the Tang army, and at this time, Xue Rengui, who was riding a white horse, had led tens of thousands of Tang cavalry to fight under the Guancheng.

Lu Dongzan at the head of the city only felt a dizziness in his brain, that's right, as smart as him, if he doesn't know that he has been tricked at this moment, then he will live in vain, don't look at the Tang army under the city, but they have no intention of attacking the city, if Lu Dongzan leads the army to fight at this moment, he dares to guarantee that the white horse general under the city will not hesitate to turn around and flee, and the damn kite flying tactics will be repeated again, but what if you stick to it?

All the food in the city is only five hundred yaks, for fifty or sixty thousand mouths, this is just a day's ration, and what about the forage needed for fifty or sixty thousand war horses? As long as you don't eat forage for a day, no matter how good the war horse is, it will not be able to take a step, and sticking to it can be said to be a worse decision than pursuit.

After a long time, Lu Dongzan finally made a decision, since there was no way out, then there was only a death fight, he ignored Xue Rengui, who was showing off his martial arts under the city, cooked and killed all the yaks in the city, and after a full meal, he took tens of thousands of horses to the mountain road of the plateau.

Now Lu Dongzan has only one belief, that is, to risk his own life, but also to crush the Tang army camp on the front line, as long as he can open even a gap for the main army of Songtsen Gampo, then the Tubo people have lost before, all will be won back, this is his last pounce.

"Abandon the defense, I can't imagine that Lu Dongzan actually made the worst move, brothers, our army will win a big victory in this battle, follow me into the city." After getting the news that the whole Tubo army had withdrawn from Guancheng, Xue Rengui rushed into Guancheng first, and more than 50,000 cavalry under his command instantly guarded the key crossings in Guancheng, and the city defense changed hands, and the first thing Xue Rengui did was to use ice water to water the gate of Xicheng and block the way for the Tubo people to return to Guancheng.

After half a day's march, when Lu Dongzan was about to see the main battlefield of Tubo, which had been separated for a long time, an ice wall appeared in front of him in a desperate posture, which was exactly a defensive line cemented by the 20,000 defenders of Guancheng led by Zhi Zhi Sili, a defensive line that could not be broken by manpower in a short time.

"Poof."

Blood spit out of Lu Dongzan's mouth without money, and almost all the generals of the Tubo army who understood the meaning of this ice wall were also gloomy, they had been sealed in this narrow mountain road by two ice walls, and there were cliffs made of solid ice on the front and back.

"I never imagined that the glaciers and snow that accompanied me in my Tibetan life would be the culprit that ended everything for us. I'm not reconciled, I'm not reconciled・・・・・・"

In a fit of rage, Lu Dongzan had lost his mind, he could no longer think calmly, rolled off his horse, shouted that I was unwilling, and walked towards the ice wall blocking him with difficulty. "Pounding."

A dull crashing sound sounded under the ice wall, and Lu Dongzan finally chose to die under the ice wall, he failed Songtsen Gampo's expectations of him, failed all the Tibetan people, and had no shame to face them alive.

Many Tibetans expressed their highest respect to this great minister who had fought for the Tibetan people all his life in their own way, and then followed his footsteps and rushed to the ice wall. "Pounding, pounding・・・・・"

The continuous dull sound knocked on everyone's heart, and also shattered the courage of more people, on the city, looking at the Tubo people who were angry to die, Yang Lin showed a trace of unbearable expression, death is death, why did he feel uncomfortable in his heart, although the Tubo people who did not have the courage to hit the ice wall with their heads were qualified to live, but Yang Lin looked down on them in his heart.

Half an hour later, no Tubo people used their heads to hit the thick ice wall, and Yang Lin's order was finally issued at this time, the Tubo army, whoever handed over their weapons and horses, and those who surrendered to the ground could be spared death, and they would be allowed to become slaves of the Tang Dynasty.

The surrender and placement of more than 50,000 Tibetan prisoners kept the Tang army busy for two whole days, and Yang Lin found Lu Dongzan's body under the blood-covered ice wall, and he planned to bury it here, and set up a tombstone for him, this is a person who should have been generous and brilliant in this era, and it was a pity to die here like this.

On the other side of the ice wall of the main battlefield, the Tubo people don't know what is happening here, many leaders are gathering in the big tent of Songtsen Gampo to make noise, their food and yaks have been eaten, but the damn war has not yet come to an end, they began to question Songtsen Gampo's decision, if you don't have food, who cares if you are Zampu or not.

Yang Lin on the ice wall saw all this with a telescope, and from their expressions, they could roughly analyze the meaning they wanted to express, Xue Rengui stood beside Yang Lin as a deputy for the first time, looking at the ice wall dozens of zhang high and hundreds of zhang thick, Xue Rengui gave Yang Lin a thumbs up in his heart, this is the guy who blocked the 700,000 Tubo army, in the world, this young horse master can be said to be the first person to play ice! "It's time to open an opening for the Tubo people to breathe, are you sure to seal the mouth again?" Collecting the binoculars, Yang Lin said lightly, 700,000 Tubo people are digging day and night, this valley is no longer much deep, and during this time, Songtsen Gampo has deployed some grain and grass materials from the plateau, but now it is the coldest time of winter, the snow covers the mountains, the road is difficult to travel, even if there is a yak team that is not afraid of wind and snow, the speed of travel is also extremely slow, and it is too late to arrive before Songtsen Gampo runs out of food.

"No problem, the most elite warriors of the Tubo army have been defeated by us, and the rest of these people have been able to graze and grow the land, and they are by no means the opponent of my regular army of the Tang Dynasty."

Xue Rengui took a sentence with a smile, and then turned around and went down to arrange, Yang Lin liked his advantage the most, and he was thorough at all.

If Songtsen Gampo decisively chooses to withdraw the army now, and does not accept Yanglin's follow-up move, then what he will lose is only 100,000 elite young men led by Lu Dongzan, on the contrary, he is very likely to receive the supply of grain and grass alive, and successfully return to Luo, and Yanglin does not dare to catch up with the plateau at all, once the Han army under his command reaches the Tanggula Pass, there will be serious altitude sickness, and the cold weather is enough to make the Tang army killed and wounded, which Yanglin does not want to see.

But if Yanglin gave Songtsen Gampo a glimmer of hope to break through the defense line, it would be different, not to mention that the Tang army camp had enough food for his 700,000 troops to eat for half a month, which was a huge bait, and the grain hoarded by the entire wealthy four towns in the Western Regions over the years was enough for his 700,000 army to eat for several years, and once the Western Regions was taken, his strategic reserves and depth would be more than doubled, enough to compete with the Tang Dynasty.

In Datang, all parts of southern Xinjiang and Jiaozhi, which have begun to feed back to the central court, will send more than one million stones of grain to the Western Regions every year, plus the people of the Western Regions have been able to produce and be self-sufficient, resulting in the overcapacity of Datang's grain production capacity now, and the problem of food and clothing has long been solved in Datang. When Li Shimin began to transfer grain to the Western Regions in large quantities three years ago, he may not have the intention of luring the Tubo people to attack, but the Tubo people found a better time entry point, which almost made the Tang Dynasty scramble.

Boom, there was a sound of the ice wall collapsing, and the Tubo people in the ice cave actually saw the Tang soldiers up close, this is the result of them breaking through the ice wall, although they don't know why the ice wall, which can't be split with a heavy axe, suddenly burst into such a big crack, but they still howl excitedly when they broke the ice wall, and after a month and a half of hard work, they finally broke this ice defense line.

The sound of the horn sounded from the Tibetan military camp, Songtsen Gampo was excited, the leaders of the various tribes who opposed him to continue to march were silent, and Yanglin set a trap for him that he had to fall into, and he got into it without the slightest excitement.

The Tubo people with knives and guns in their hands launched a fierce impact on the crack mouth, the Tang army used bows and arrows and spears to resist the charge of the Tubo people, while trying to use ice water to pour the crack mouth again, in front of the narrow crack mouth, the Tubo people fell one by one, their bodies were quickly thrown behind by their comrades, the living Tubo people rushed up again, and were killed by the well-equipped Han army again, but due to the narrow passage mouth, the Tubo people did not die many people each time, for their base of 700,000 people, it is simply not worth mentioning.

In this way, at the mouth of this narrow passage, the Tubo army and the Tang army fought fiercely for a day and a night, ending with more than 5,000 casualties of the Tubo army, the Tang army finally sealed the chiseled passage mouth again with ice water, and the not very willing Songtsan Gampo did not intend to let the Tang army pour the ice wall unbreakable again, this time he planned to personally supervise the battle, send his most elite subordinates, and strive to break through the ice wall in one fell swoop, seize the Tang army Dazhai, and then take the entire Western Regions.
