(I haven't written it for a while, but I'm actually a little handy, and I'll change two thousand words today, and I'll change it tomorrow.) ）

Li Yu attracted the main force of the Tubo army to confront Taoshui with the main force of 90,000 troops, led the partial division to attack and harass the enemy's rear with Ye Shi Liangsuke, and Li Wentong made a long-distance attack on Hezhou, and the battle situation in the Taoshui Valley was determined in the first battle. When the news of the victory reached Chang'an, it was really full of praise for Li Lianggong. It's not true to say that everyone is happy, it's just that there is a lot of joy in Chang'an City, and you can't hear the cries of the orphans of the four field dead.

"Although our army won a great victory in this battle, the army suffered heavy casualties, and I am afraid that we will not be able to enter Shanzhou westward in the short term."

In this battle, Li Yu beheaded 50,000 people and captured more than 20,000 prisoners, but it was a tough battle, killing 3,000 enemies, losing 800 himself, killing more than 18,000 soldiers, seriously wounding more than 5,000, and lightly wounded abounded.

"Fortunately, Hezhou and Shanzhou are not far apart, Li Yu only needs to send a partial division to cooperate, and the heavy responsibility of attacking Shanzhou is still handed over to Hao Jue. Otherwise, there are more soldiers and horses surrounding Shanzhou, but I am afraid that there will be more dragons and will not be able to cure the water. ”

The edict ordered the general Li Wentong to lead the 7th Army of the headquarters, the 72nd Army of the Tun Army, and the new attached army of the Ye Shiliang Auxiliary Department with a total of 35,000 people to march into Shanzhou, under the control of Hao Wei, the commander of the Right Route Army. Bai Zuwang, the general of the Fengxiang Army, was promoted to the post of soldier and horse envoy of the Twelfth Army, leading the two brigades of the Twelfth Army and five thousand soldiers to be stationed in Hezhou, and the rest of the Twelfth Army was stationed in the castles of Hezhou as the backup of the army.

The edict ordered the headquarters of the Baoyi Army to move to Linweiyuan, and Li Yu led the 11th Army, the 1st Army, the 2nd Army, and the 2nd Guards Army to be stationed in Didao to recuperate and replenish the troops.

After Li Yu's protection, the imperial court appointed Tian Zhixing as the training envoy of the He and Tao regiments, and Li He as the deputy envoy of the regiment training, supervising the training of 10,000 soldiers from Erzhou County. He also sent Linghu Chu, Su Quan, Niu Seng and Ru, Li Shen and other clerks to serve in the two states. Li Yu also issued an edict to transfer 100,000 yuan of rice and grain from Taicang, and 50,000 yuan of money to Longyou for the purpose of appeasing the people. Li Yu specially said to Zheng Quan, who was going to appease Longyou:

"Aiqing and remember, this money and grain are not distributed to the people, and I want to use this money and grain as the seeds of Longyou's revitalization."

The revitalization of Longyou's thousands of miles of fertile fields is naturally not something that can be done with such a little money and grain, Li Yu means to use these money and grain to unite people's hearts and develop various basic undertakings such as road construction and farmland in Longyou, Zheng Quan naturally prepared with a heart. After arranging the affairs of Longyou, Li Yu began to think about Hexi again. At this time, Li Guangyan was also facing the heavy snow, wondering where did the pioneer Shi Jingfeng go?

The heavy wind and snow slowed down the pace of Li Guangyan's march, at this time after Li Guangyan came out of the division, the 100,000 elites of the department except for a few battles in succession at the beginning of the river crossing, did not encounter a large enemy army, now the army has reached a tacit understanding with the Liangzhou Uighurs, crossed Liangzhou, and directly took Ganzhou, one of the pioneers, Sha Chali, has led the Shatuo troops to attack Changsong, but there is no news of Shi Jingfeng, who was pinned on by Li Guangyan.

"Could it be that this history worship is in name only, and it has lost its direction in the vast desert?"

Li Guangyan asked himself, his eyes fixed on the map in front of him again. In the vast desert, there are only a few thin lines indicating that this is a road, and in some places it is even a dotted line. Li Guangyan knew that even so, it was only after the Department of Grain and Straw Statistics spent a huge amount of manpower and material resources to find out. If Shi Jingfeng had taken such a route, Li Guangyan believed that he would not have lost his way, but he would not have reached Ganzhou on time, because there were nomadic tribes around these roads. Shi Jingfeng is more likely to take some sparsely populated routes. Looking at the mountains, lakes, and some seasonal rivers on the map, Li Guangyan had no clue, and only hoped that when he arrived in Ganzhou, Shi Jingfeng would suddenly emerge from somewhere.

"Will he lead the army to attack Yumen Pass?"

Li Guangyan suddenly had such an idea in his mind, Yumen Pass to contain the Hexi Corridor, if Shi Jingfeng can successfully attack Yumen Pass, it will be a great achievement, but why should he attack Jiancheng?

Li Guangyan was thinking about it, and the curtain of the big tent was lifted. Xiahou Cheng came in and said:

"Qi Yu Marshal, Shatuo Department came to report, Sha Zha Li Department sent troops to Changsong, braved the snow to fight, defeated the Tubo army under Changsong City, and forced the Tubo army to retreat into Changsong County, but the weather was cold and snowy, and the Shatuo Department was unable to attack the city, please move to Changsong and preside over the plan."

I don't know if it was stimulated by the news brought by Xiahou Cheng or the cold air brought by him, Li Guangyan's face changed, and his fingers quickly moved from Yumen Pass to Changsong on the map, but he only clicked a little on the county seat of Changsong, and pressed down on a place and said:

"Damn! If you can't win completely, you rush to battle, and you can startle the snake, and you can startle the snake! ”

Xiahou Cheng could see clearly that the position that Li Guangyan was pressing was Herong City.

Herong City was built in the Dazu period of the Empress Wu, and it was Guo Yuanzhen, a famous general who was the governor of Liangzhou, who presided over the construction of the city. "Tang Shu Guo Yuanzhen Biography" records, "First of all, Liangzhou was only 400 miles north and south, both forced the Turks and Tibetans, and the two Kou were dying to the city, and the people suffered, Yuan Zhen began to place Herong City at the mouth of the gorge in the south, and placed the Baiting Army in the north boundary (now in Minqin County), controlling its main road, which was 1,500 miles from the Tuozhou border, and it was the ...... of the Kou captives who did not return to the city. "Since Guo Yuanzhen built the city to guard against Tibet, the terrain is naturally not an ordinary danger.

Herong City was built at the mouth of Nangulang Gorge in Changsong County. Gulang Gorge, which is commonly known as "Jinguan Silver Lock", has abrupt mountains and rocks, dangerous terrain, and has been famous for its important geographical location of "post road leading to three auxiliaries and five cool gorges of the gorge gate" since ancient times. If the Tibetan army concentrated its forces around Herong City and retreated to Gulang Gorge, then it would be difficult for Li Guangyan to advance another inch. The southern part of Gulang Gorge is the intersection of high mountains and plains, where the Tubo people live, if they can't get Herong City and control Gulang Gorge before the arrival of spring, the Tubo reinforcements will come in a steady stream.

Xiahou Cheng obviously also knew the importance of Herong City, and at the moment he was pounding his fist:

"These Shatuo people, every time they only think about snatching money, they will go up if they are profitable, and they will retreat if they are not profitable, if they are like this, our army is only afraid that the battle of Ganzhou will cause them chaos."

Every time the Shatuo army captures a place, no matter who the target is, whether it is rich or poor, it must be robbed first, and after Li Guangyan severely reprimanded it, Sha Zhali restrained his subordinates a little and no longer harassed the Han people. That's it, the reputation of Li Guangyan's army has been ruined, and no matter what people are, they all stay away, and even many people have fled to Liangzhou under the rule of Hui. Li Guangyan was not happy in his heart, but he suppressed it and did not have a seizure, and ordered:

"The order was given, and General Cui led 5,000 cavalry to reinforce the governor of Shazha Lidu and besiege Changsong. General Xiahou, you have to lead 3,000 cavalry to Gulang Gorge to test one or two. ”
