Finally can retreat, must also retreat, if you don't go, then I'm afraid that I don't have a chance to go - Khotan is an important gateway for Tubo to enter and exit the Western Regions, with the righteousness of Fu Yanxiong, the only gate in the hands of the Tubo people has been slammed shut, the Tubo defenders who are cowering in Shule and other cities are now the turtle in the urn, and there is no slightest strength to struggle, the Tang Anxi army can wait for next spring, and it is not too late to clean up one by one, as for the main force of the Tubo army in Tuyuhun, in addition to sitting and watching the Anxi Tubo troops fall one by one, There is nothing to do at all, the reason is very simple, with the approach of winter, the Kunlun Mountain Pass has reached the time of heavy snow to close the mountain, and it is necessary to get the passage to resume in March and April next year, by that time, the Anxi Tubo army has already been wiped out, besides, the Tubo people were so troubled by Li Xian, they are sad this winter, there is a famine in the spring of tomorrow, how can there be any spare strength to transfer troops to attack the Western Regions, I am afraid that I will have to worry about taking the opportunity to launch a spring offensive, and the defense is too strong, let alone sending a large army to attack the Tang Dynasty.

All in all, the Tubo people have not gone through several years of recuperation, so they don't want to go abroad again, but then again, it is precisely because they are worried that they will launch a spring offensive next year, and the Tubo people are more and more eager to hold Li Xian such an important hostage as a barrier, in other words, once the news of Fu Jiaxiong's uprising reaches Fu Qi City, it will inevitably stimulate Gar Qinling to launch all the main forces at all costs, in order to completely annihilate Li Xian's troops, and at that time, Li Xian does not dare to guarantee that his troops can escape smoothly.

Retreat is inevitable, but how to retreat, retreat by that route is very particular, must be carefully calculated, in general, Li Xian's troops to return to the territory of the Tang Dynasty There are five ways to go:

First, take Songpan into Sichuan, this road is far away, not to mention, and there are many dangers and obstacles along the way, it is very difficult to go quickly, as far as the current time is concerned, even if the Tubo people do not intercept along the way, Li Xian's department can not rush back to Datang before the heavy snow closes the mountain, obviously, this road is not passable.

The second road is to take the Tangbo Ancient Road, through Shanzhou (now Xining) across the river and Huang Valley, back to Tianshui, this road is relatively flat and easy to walk, but unfortunately it is very difficult to work, just because Shanzhou is now besieged by the Tubo army, although there are more than 30,000 troops under the general Gao Wei of the left prison guard, but it can only barely protect himself, it is really difficult to divide the troops to meet the Li Xiansuo who returned to the east, and the consequence of the lone army can only be to send credit to the Tubo people.

The third road is the road when walking, back to Lanzhou through Babaochuan, this route Li Xian is the most familiar with, and it is also the most convenient to go, but the strength of the Tubo army in this direction is the strongest, as far as Li Xian has such a small number of troops in his hands, there is no hope of breaking through at all, if he wants to go, he can only be dumped by the Tubo people, and even a horse bone may not be left.

The fourth road is the most precipitous, just because this road to Zhangye is a rugged mountain road, strange and dangerous, people and horses trek in it, a little carelessness will have the misfortune of broken bones, this road is not much of the Tubo army, as long as Li Xian's troops can quickly bypass Fuluochuan City, they can escape into the continuous Qilian Mountains, the Tubo army wants to chase is difficult, this road was originally the last escape road reserved by Li Xian - this road is the mountain road taken by the medicine pickers, the locals know very little, and Li Xian can know, Because Li Xian was a "travel friend" when he was in college in later generations, he traveled this road with people and had an understanding of the geographical situation along the way, and it was very likely to achieve unexpected results by taking this road, and the premise was that Li Xian could break through the encirclement of the Tubo army on the front line of Fuluo River, and this, although it was difficult, was not completely impossible, and it was possible to plan carefully.

As for the fifth road, there is no doubt that it is the Kunlun Mountain Pass that has just been taken, just bypassing the dangerous place of Dafeichuan and going straight to the Kunlun Mountain Pass, although this road is more difficult, but it is better than the main army of Tubo along the road, Li Xian's department can completely let the horses run wildly, all the way to Khotan, of course, this refers to the Tubo people did not react, according to Li Xian's view, once the resourceful generals such as Gar Qinling learned that Khotan had rebelled, nine times out of ten they would deploy troops to block this passage, obviously, if they want to go this way, First, we have to rush for time, and second, we have to plan carefully and create some illusions to confuse Gar Qinling before it can be realized.

Generally speaking, except for the fourth and fifth two roads to succeed in the greater grasp, the rest are dead ends, and only the Tangbo Ancient Road seems to have a glimmer of extremely slim hope, but basically negligible, take the four roads and the first half of the second road The route is the same, you have to cross the Douman River, and take the fifth road you need to wade through the Buha River, the two rivers are not the same way, the latter is located on the northwest side of Qinghai Lake, and the former is located in the southeast corner of Qinghai Lake, both rivers are inland rivers in Qinghai, fortunately it is the dry season at this time, The water of the two rivers is very shallow, people and horses can wade through, and there is no need to build pontoon bridges, the difference is that the line of the river is close to the city of Fuluochuan, and the guard is relatively tight, while the Buha River is close to the Wuhai Sea, and after just experiencing a big battle, the garrison is relatively weak.

"Report, Your Highness, more than 10,000 dogs were found in the west, and they were less than twenty miles away from our army."

"Report, Your Highness, there are nearly 10,000 enemies from the north, and they have reached Xiaoling, and there are still eighteen miles away from our department!"

Without waiting for Li Xian to think about the specific route and steps of the retreat, the two newspapers had already sent back the news that the chasing troops were coming, in desperation, Li Xian had to interrupt his thinking, and ordered the whole army to quickly pack up the camp, ready to continue to play a game of cat and mouse with the Tubo people, although the order was quite hasty, but all the troops had long been accustomed to the rules of the game, and the action was very fast, and in less than a quarter of an hour, more than 4,000 soldiers were ready to go.

"The whole army obeyed the order, except for the seven days' rations, discarded all baggage, hurried to the mouth of the Buha River, we went home, dare to block the way, kill!"

While the sergeants were tidying up, Li Xian finally made up his mind, first releasing the eagle for communication, and then, in front of the whole army, issued an order to withdraw his troops.

"Kill, kill, kill!"

After more than half a month of hard fighting, a group of soldiers have already returned to their hearts like arrows, and when they heard that they could finally go home, they were all excited, and the passionate shouts of killing sounded to the sky, and they rushed straight out of the clouds......

Buha River is located in the northwest of Qinghai Lake, originates from the north foot of the Rigenfeng of the Shule Nanshan Mantan in the branch of the Qilian Mountains, roughly flows in the northwest-southeast direction, extremely beautiful, like a green ribbon meandering in the desert grassland, the prairie on both sides of the river bank is the famous summer pasture of Tuyuhun, every spring and summer intersect, the tribes gather here, the green grass is like a tree, cattle and sheep are everywhere, a group of "wind blows grass and sees cattle and sheep" beautiful scenery, of course, that beautiful scenery must be seen in summer, when the severe winter is coming, the grass and trees wither, There is a dead silence on both sides of the strait, there are no people for thousands of miles, only the biting cold wind is whistling endlessly, how can it be desolate, but this kind of vast and uninhabited scene is the situation that Li Xian, who has fought all the way to here, wants to see the most, just because after crossing this river, it is already a smooth road, except for the Kunlun Pass, there are no other dangers.

It's not easy, it's really not easy, looking at the gurgling Buha River in the distance, Li Xian's eyes couldn't help but moisten a little - from the moment he decided to withdraw from the army, it has only been three days now, but what a difficult three days, not to mention how fortunate the trek of thousands of miles was, not to mention how dangerous the encounters along the way were, it was said that in order to confuse Gar Qinling, Li Xian didn't know how many brain cells had died-Li Xian's troops first rushed to the mouth of the river like a rainbow, At the cost of hundreds of casualties, he broke through the two Tubo 10,000 troops who came to intercept in a row, and let the Gao Wei Department who held Shanzhou pay the price of more than 1,000 casualties, forcibly launched an offensive, and made the illusion of receiving Li Xian's department, and then Li Xian's department took advantage of the cover of the night, turned halfway, and did not hesitate to exhaust nearly half of the horses at the cost of running for more than 400 miles in one day and one night, and finally jumped out of the cage of the Tubo army, and rushed to the mouth of the Buha River with great difficulty, at this time, Li Xian's department was only left with only 3,200 remnants, Originally, there was only one person and one horse left in the equipment of one person and three horses, and this kind of sacrifice and such a price can only be described in one word, that is tragic!

It's really too tragic, although I know that "Ci is not in charge of the soldiers" is the most reasonable saying of the soldiers, but after all, people are not machines, the heart is always long, seeing the robe Ze fall all the way, Li Xian's heart sank as if poured lead, fortunately, all this is finally going to end, can successfully take back Anxi, and can delay the rise of Tubo, Li Xian has nothing to regret, as for the blood feud of the robes, Li Xian believes that there will be a day to get back, and there is only one important task at the moment, that is, to cross the river!

"Woo woo woo ......"

The river is obviously not so good, the heavens seem to be playing a joke with Li Xian, just as Li Xianyang is about to order the whole army to rush across the Buha River, a terrible horn sound suddenly sounds, and then I see a small mountain beam behind the smoke and dust, thousands of elite Tibetan cavalry roared towards Li Xian's headquarters.

Not good, in ambush! As soon as he saw the Tubo cavalry rushing over the mountains and fields, Li Xian's heart sank, but now, under the fatigue of people and horses, it is impossible to get rid of the Tubo cavalry's cover-up, and the only way to go is to fight, to kill and kill, and to kill a bloody road!

"When the two armies meet, the brave wins, sons and daughters, kill the thief with this king, kill, kill, kill!"

Can't hesitate, and there is no time to hesitate, in the face of the surging Tubo cavalry brigade, Li Xian took off the Qinglong Yanyue Sword on the victory hook, raised it high, and issued the most passionate battle declaration......
