From Liangzhou to Lanzhou to go through Gulang, and then through the edge of the Guzang South Mountain, to Wucheng to capture, and then along the Wu against the water, break Guangwu, and then Lanzhou, Huo Qubing conquered Hexi along this road from east to west, and now, Shen Long will lead the army to go retrograde Huo Qubing walked the road back to Chang'an.

Gulang, Guzang Nanshan and Wucheng can't accommodate too many defenders, so they are relatively easy to Shenlong along the way, and they don't even need Tang soldiers and horses to fight, and they will solve it with their servant army.

The same was true for Guangwu, who encountered far fewer obstacles than originally expected, but neither Shen Long nor Guo Xin let down their guard because of this, but became more vigilant.

"Tubo will definitely not let me wait to return to Datang, if Hexi and Longyou are reopened, Datang and the Western Regions will be able to train together, and continue to send troops to the Western Regions, and the merchants who come and go can also provide countless taxes to Datang, and the Tubo people don't want to see these happen anyway!" Guo Xin said.

Shen Long nodded in agreement, originally the Western Regions had been swept away by Tubo, they almost didn't have to worry about the problems of the Western Regions, they could transfer their forces to the border with the Tang Dynasty to use, and continue to maintain the threat to Chang'an, but now, the Anxi Protectorate and the Beiting Protectorate have re-emerged, and Tubo will face the situation of being attacked by the Tang Dynasty on both sides, and Trisong Dezan will definitely do his best to prevent them from returning to the Tang Dynasty.

"Don't worry too much about the protection of the capital, now Tubo is also facing the threat of Nanzhao in the south, Jiannan Road has the threat of Datang, and the internal roads of Tubo are difficult, even if they want to, it is estimated that they will not be able to transfer too many troops and horses, and they can only transfer troops from the place next to Hexi and Longyou." This was a strategy formulated by Li Mi for the Tang Dynasty, uniting with the Southern Zhao and the Uighurs to contain Tibet.

The Southern Zhao attracted the attention of the Tibetans in the southwest, the Uighurs maintained their suppression of the Tibetans from the north and the Western Regions, and the Tang Dynasty launched an attack from the Jiannandao and Fengxiang armies.

It's a pity that Tang Dezong has been thinking about the grievances with the Uighurs, and he has been unwilling to unite with the Uighurs, so that the Tang Dynasty misses the opportunity, and when he finally figured it out, Li Mi has run out of time, otherwise, maybe Hexi and Longyou would have returned to the Tang Dynasty long ago.

"And the last general thinks that the more troops sent by Tubo, the better, sooner or later, we will have to do a battle with Tubo, instead of us attacking Dafeichuan, it is better for the Tubo people to come down from the plateau and fight us in Lanzhou!" Altitude sickness is the best weapon for Tubo to resist the Tang Dynasty, and once they come to Lanzhou, then this factor that restricts the combat effectiveness of the Tang Dynasty soldiers and horses does not exist.

The Tang Dynasty soldiers and horses can fully exert all their combat effectiveness, and in such a situation, it may be difficult for the Tubo people to win; In the course of the war between the Tang Dynasty and the Tubo for many years, the fiasco of the Tang Dynasty mostly occurred on the plateau, while the defeat of the Tubo people mostly occurred after they came down from the plateau.

The Tibetans are like a strong football team at home, they can often achieve good results on their home field, and once they come to play away games, they immediately kneel; The home dragon and away bugs are probably them.

"If there is no miasma, why am I afraid of Tubo?" Guo Xin also deeply believes that the people of Datang do not understand the truth of altitude sickness, and they explain the discomfort of people after going up to the plateau as miasma.

"Weizhou is too close to the Tang Dynasty, if there is a big war, my Tang Dynasty will definitely be able to get the news, and at that time, as long as there is a soldier and horse from the rear, Tubo will be defeated, so Lanzhou has become the most suitable battlefield!" Shen Long pointed to the map and analyzed, large-scale operations are also not available anywhere.

It is not easy for the Tang Dynasty coalition army to transport grain and grass, and the same is true for the Tubo people, and only a big city like Lanzhou can collect so much grain and grass for the use of the Tubo army, and with the influence of distance, this decisive battle will inevitably take place in Lanzhou.

Therefore, after taking Guangwu, Shen Long stopped and repaired for a few days, and only after the soldiers had washed away the fatigue of the march did they slowly approach Lanzhou City, slowing down the speed of the march along the way, and constantly sending scout horses to investigate the situation ahead, so as not to be suddenly attacked by the Tubo.

The Tubo people did not intend to let them arrive in Lanzhou so easily, and there were constantly small armies harassing them along the way, but Shen Long could use the ability of the shapeshifter to possess the eagle birds in the sky and conduct a large-scale search, and the fog of war became unilateral and transparent in front of Shen Long.

This is tantamount to opening a hang-up for the Datang soldiers and horses, the Datang soldiers and horses can find the enemy troops within a radius of dozens of miles at any time, and those enemy troops don't know that they have been discovered, and they are still dreaming of a successful sneak attack, but each attack happens to fall into the encirclement of the Datang Dynasty and is easily solved.

After coming and going, the harassment of Tubo not only did not slow down the march of the Tang Dynasty coalition army, but lost a lot of soldiers and horses, although the number of each harassing team was not large, but the sum of so many people was not a small number.

Seeing that the harassment was ineffective, the Tubo people could only give up, while the Tang soldiers and horses continued to advance steadily without hurry, and then finally arrived at the edge of Lanzhou City and saw the Tubo army that had been waiting for a long time.

"Ha, Trisong Dezan has made a lot of money this time! All the soldiers and horses of the Hexi and Longyou generations should be here, right? Looking at the camp of the Tubo people from afar, Shen Long said.

"I'm afraid there are almost 200,000 troops!" Guo Xin couldn't help but sigh, since the Anshi Rebellion, he had never fought against such a large-scale enemy army.

"Hehe, the number of our army is far inferior to that of the Tubo, are you afraid?" Shen Long looked at Prince Bahanna, Gu Lulu, Kang Guangde and the others and asked.

Shen Long had a total of 12,000 Han Navy under his command during this expedition, including the white-haired soldiers, the young soldiers of Chang'an, the people of the Tang Dynasty who were rescued from foreign races, and the servants who were loyal to the Tang Dynasty.

The rest also had a Uighur army of 30,000 men, led by Gu Lulu, Wei Yuanfang, and other Uighur Ye Protectors; There are more than 10,000 Shatuo troops, 20,000 servant troops, and excluding the soldiers and horses stationed in Suzhou, Ganzhou, Liangzhou and other places along the way, there are only 50,000 people who have come to Lanzhou to fight a decisive battle with the Tubo people.

In terms of numbers, the Tang soldiers and horses are only a quarter of the Tubo people, and the situation does not seem optimistic, but the Tang army under Shen Long is not nervous at all, "Most of the capital guards, through strategy, what are the fears of just 200,000 soldiers and horses?" ”

"Good! Then if we win this battle, we will go home! ”
