The Zang River, later known as the "Brahmaputra River", originates from the Jemayangzong Glacier at the northern foot of the Himalayas in the southwest of the Qiang Region, and is one of the most abundant water resources in the world.

Its source in the Gangdis Mountains is called "Marong Zangpo", which means "river" in the Tibetan language, and is at a right angle of about 90 degrees to the direction of the Peacock River, which also originates from the same source, and is also a natural trade route from the western border of Nibhara to the Zhangzhung or Tibetan region.

Yang pre for such a terrain, is no longer unfamiliar, the kind of hard rammed earth road, without a certain national strength is not built, because the road construction is just the beginning, maintenance is extremely manpower and material resources consumption, with the wealth of the Tang Dynasty, Guanlong everywhere is still using the Qin Chi Road thousands of years ago, and the reason why Guanzhong can be the foundation of the emperor is also because of its convenient transportation.

Such a road, in the four towns of Anxi is rare, not to mention the outside of the place, since stepping on Bolu, has never been encountered, the general march, all in the plains, river valleys, mountains, pack horses are born in the best, although the size is not large, can trek through mountains and rivers, such as walking on the ground, unlike his mount, always feel careless will break the foot.

In such an environment, the cavalry was really not as brisk as the footmen, and he raised his head to look, and the aggressive who was striding like a fly in front of him reluctantly pulled the halter and pulled the horse back to the narrow mountain road, and the clods of earth lifted by the horse's hooves rolled down from the height, and it took a long time to make a slight echo.

Fifty-two men, one hundred and seven horses, and when they had crossed the pass, there were only so many left, and seventeen horses had stumbled and fallen off the cliffs, and if it had not been for a man like Tycoon, who was accustomed to walking the mountain paths, he might have been much less many.

His men met the fierce in the upper reaches of the Peacock River, and it was too late to prepare at that time, so they notified one by one, slowly assembled on the road, and when they crossed the mountain pass, the whole team was already here.

Yang Yu was proud to have such a subordinate, and he wanted everyone to see that even when marching on such a mountain road, light cavalry was faster than foot soldiers.

Du Guli only notified them, and then his people went to inform the people who were fighting in the pit, and the two sides didn't even fight each other, what would Zhang and Xu do? He didn't know, and he didn't want to know, he only knew that he had to be fast, and only fast could he meet Liu Ji's requirements.

The road ahead is unfamiliar, the enemy is unknown, but he has no fear, this confidence comes from continuous victories, siege and fortification, cavalry is of little use, chasing the dead and chasing north, and lacking a sense of accomplishment, he has long been looking forward to this day.

The steep mountain roads and high altitude are completely different from the climate of the Peacock River Valley, and they seem to have passed from the hot summer to the cold winter, and they have to tie their sleeping covers to the outside of their clothes and armor to try to block the pervasive highland monsoon.

In just a few days, they have increased the average altitude by a full thousand meters, and they are about to set foot on the Qingqiang Plateau, the highest region in the world.

"This should be it." The one who was walking in the front stopped and built a pergola with the palm of his hand, looking into the distance.

Yang Yu took a few steps forward and stood with him, what he saw in front of him made him stunned, only to feel that his heart suddenly lifted, and there was a feeling of sudden enlightenment.

Looking down from the mountain pass where they stood, there was a slightly sloping green earth, and in the distance a white ribbon meandered, and the cattle and sheep were driven by the shepherds on this rich plateau, enjoying the unrestrained nature.

"Is that the river your Shangguan said?" Yang Yu couldn't bear to spoil this beautiful scenery for a while.

"The direction is good, the goal will not be wrong, he told me that this is just the source of the big river, the depth of the water can be waded, but if there is a torrential rain will cause a flash flood, it is impossible to predict, along this river all the way, there will be many forks, one of which leads directly to the capital of the Tibetan people, Luo."

When he set out from the western border, he only knew that his target was in the territory of the Tubo people, and he didn't have much idea where it was, because this area had never been set foot in by the Tang people.

But listening to the aggressive tone, even he didn't know the truth here, and he heard it all from Goro, but how did Gorou know? You must know that in the more than ten years he has been in Anxi, he has almost never lost his whereabouts.

"There is a city ahead, it is an important town on the border of the Tibetans, called Gongtang, it is a mountain city, and it is also our goal, the place where we will go."

"Siege?"

"Of course not, our goal is to delay the target's actions and create fighters for those behind." The aggressive words made him stunned.

"How many people are you talking about?"

"When I left the Qionglong Silver City, there were more than 400 of them, all of them were Tibetans." Douguli said calmly: "I am only responsible for leading the way, and it is up to you to decide how to do it." ”

Yang Yu turned around, and behind them, there were Tang sergeants leading horses and walking between the mountain roads, their footsteps were staggering, physically and mentally exhausted, only a pair of eyes, still in spirit.

One by one, his men climbed up the mountain pass, and gathered around him, and men and horses stood all over the pass, and every man's eyes were fixed on his general.

"The road ahead is unpredictable, and once we get here, we will advance and not retreat."

Facing everyone's eyes, he drew his sword out of the sheath and stepped on his war horse: "Take the fame in the enemy's territory, raise the country's prestige in a foreign country, at this time, sons, get on the horse, follow a certain ......"

"Kill the thief!"

"Kill the thief!"

Fifty shiny horizontal knives pointed to the sky, fifty You Yi were all equipped one by one, Yang Yu had already galloped away first, and there was no space to arrange the formation at this time, they could only swarm down from the hillside, like a whirlwind rolling up in the flat ground.

In order to achieve the effect of surprise, they did not stop any longer, they had to race against time, so the tribes of all sizes along the way were stunned to watch a team with bright armor and red flags roaring by.

The team, neither looting nor killing, only attacked when they tried to stop or report the news, and then without hesitation, they went straight to the shore of the Zang River, wading through the shallows, and soon approached their destination.

Lying on the side of the Zang River, it is also built on the mountain with the Qionglong Silver City, and is an important border town in the western part of Tibet.

Gongtang.
