The slight noise alarmed the sentry, who walked over to check. When he walked under the monkey, the monkey stretched out the noose that had been prepared and strangled him by the neck at once.

After solving the sentry, he supported the sentry's body against the wall with his weapon, and then, leaning against his body, threw a rope under the wall.

After receiving Zhang Hu and the others, they took the sentry of the Tubo army into the city.

Soon after, although the Tibetan army found that the sentry was missing, they thought that he had left his post without permission to go to convenience or run somewhere to sleep. Since this is currently the rear, the Tuyuhun army has been routed, and it has not aroused enough vigilance.

When night fell again, the monkey dived across the moat and reported the situation to Duhe, who took the lead in diving into the moat and entered the city through the underwater tunnels under the cover of night.

After entering the city, Du He sent people to the streets to arrest some officers and soldiers of the Tubo army, learned about the deployment of the Tubo army in Longde City, and focused on the location of the grain depot.

After understanding the situation, Du He and others found that the situation was much more serious than originally expected. Originally, the Tubo army in the city had 8,000 infantry and 3,000 cavalry, but unexpectedly, just two days ago at night, 3,000 cavalry in Mizhou City were also transferred to strengthen the defense. The number of enemy troops in the city reached 14,000, and the number of the Flying Tiger Army was more than 2,600, and the disparity was too great.

After discussing with Du He and the others, they decided to take a risk.

Du He led the 300 team members who had entered the city to attack and burn the grain depot, and Wei Chi Baoqi led 200 team members to seize the south gate to welcome the main force into the city, and to respond to the retreat of Du He and Du He at any time.

Under the leadership of Zhang Hu, Du He and others came to the Dajiaochang located in the center of the city. Due to the excessive amount of grain and grass, not only the surrounding houses and warehouses were filled with grain, but also the school yard was also full of forage.

Du He and the others approached the Daxiao Field as secretly as possible, but when they were still about 50 meters away from the Daxiao Field, they were discovered by the patrol of the Tubo Army.

Du He made a quick decision, did not entangle with the enemy, and led the team members to rush to the school field with all their might.

Around the Daxiao field, dozens of Tibetan officers and soldiers were on duty at night, and they raised the alarm while coming forward to intercept the Flying Tiger Army.

Du He and the others rushed to kill quickly, and soon killed all these Tibetan troops. Du He ordered the team to disperse and set fire to it.

When they came, they prepared lamp oil in advance and put it in the gourd on their backs. The Flying Tiger officers and soldiers sprinkled lamp oil on the grain and set fire to the grain warehouse. The haystack on the school field has already been ignited.

Longde City is located in the northwest plateau, there is wind all year round, although today's wind is not very strong, but there are about three levels. The wind fueled the fire, and the school field and its surroundings were on fire.

Seeing that the task was completed, Du He hurriedly called the soldiers of the Flying Tiger Army to retreat in the direction of the south gate.

At this moment, a large number of Tibetan troops poured out. Du He and the others are all walking, and the speed is not fast. They rushed desperately, but there were more and more enemies in front of them.

In less than 20 minutes, there were less than 100 people left for Du He and the others, and there were at least thousands of enemies around.

Du He opened the way in front, he waved the Mo knife with both hands, kept chopping, and after countless waves, his hands had begun to go numb. Suddenly, an arrow hit him in the left shoulder, he couldn't hold the Mo knife anymore, picked up a scimitar of the Tubo army, and continued to rush forward to kill.

Three minutes later, there were less than 40 people left with him. There are more and more Tibetan troops.

At this moment, the Tubo army in the south was in chaos, and thousands of Flying Tiger troops rushed over, and the first one was Yu Chi Baoqi. The Tubo army was caught off guard, and was broken through the encirclement by the Flying Tiger Army, and fought with Du He and others.

Yu Chi Baoqi saw Du He and shouted loudly: "Get on the horse!" ”

The team members who followed Du He hurriedly jumped on the back of the horses that received the team members and rushed towards the south gate.

Wang Ahan, the commander of the Tubo army in Longde City, saw that the grain and grass were burned, and he was furious, and he shouted loudly: "Don't let them go." "Commanding the troops in pursuit.

At this time, a large number of cavalry of the Tibetan army also arrived, but they were blocked by the dead corpses all over the ground and the chaotic Tubo army infantry.

Wang Ahan, the commander of the Tubo army, was anxious, and personally rode his horse in front, and while he ordered the infantry of the Tubo army to give way, he personally killed two infantry of the Tubo army who had no time to get out of the way.

At this time, the officers and soldiers of the Flying Tiger who controlled the south gate had already fought with the Tubo army who rescued the south gate. Since there were less than 2,000 officers and soldiers who entered the city to respond, only 500 Flying Tiger troops controlled the city gate, and the Tubo army that came to seize the south gate was also close to 1,000 people, so the Flying Tiger Army also fell into a bitter battle here.

At this moment, Yu Chi Baoqi and others rushed back and dispersed the enemy army, and then, the Flying Tiger Army all rushed out of the south gate and galloped towards the Guangrou grassland.

Wang Ahan, the commander of the Tubo army, led thousands of cavalry in hot pursuit.

Suddenly, in the darkness of the night, there was a bang, and countless arrows flew over, Wang Ahan was hit by several arrows, turned over and fell off his horse, and nearly a hundred cavalry of the Tubo army were also shot off their horses. Immediately, in the dark night, a large number of Flying Tiger troops rushed out with shouts.

These are the Flying Tigers who didn't go into the city, they were responsible for picking them up here.

Yu Chi Baoqi immediately turned his horse's head and rushed back with a shout.

The Tibetan officers and soldiers saw that they had been ambushed, and the commander Wang Ahan was also dead, so they had no intention of fighting and turned around and fled.

The Flying Tiger Army pretended to chase and kill for a while, and immediately turned around and fled.

The Flying Tigers suffered heavy losses, this time losing hundreds more, and now only 2,100 remain. Du He was even more unlucky, on the way to escape, he was hit by two more arrows in the back, but fortunately, the armor was well protected, but he was only slightly injured.

The task of the Flying Tiger Army was completed, and according to the plan, they retreated towards Longyou Road. At the same time, a messenger was sent to report to Xue Rengui.

Tai Chi Hall, Li Shimin's study.

Li Shimin took the report of the first phase of the battle of King Li Su of Liang and said: "King Liang and they have achieved the success of the first stage, and the Tugu Hun Nuo Hao Bo Khan has signed an agreement with Tang Fei to accept the canonization of the imperial court and declare himself a vassal to the Tang Dynasty.

As long as the second stage can repel the attack of Tubo, whether it is Tubo or Tuyuhun, after this battle, they will have huge losses and will not be able to pose a threat to the Tang Dynasty.

The southwestern border of the Tang Dynasty will not be threatened by war for a long time. The imperial court can now concentrate on peacebuilding. ”

The eldest grandson Wuji and Fang Xuanling both congratulated Li Shimin.

Li Jing said: "His Royal Highness King Liang's tactics in the second phase are very clever, he did not defend the ambush city, but sent Xue Rengui to attack and harass on the periphery, and cooperated with the defense of the ambush city, so that the Tubo army could not attack the city with all its might, this tactic is very effective.

Most brilliantly, he did not divide his troops to defend the various cities, but evacuated the small cities in advance and concentrated his forces on holding the city. Avoided being defeated by the Tibetan army.

At the same time, the fortified walls cleared the wilderness, making it impossible for the Tibetan army to replenish supplies on the spot, forcing the Tibetan army to rely on transporting grain and grass from its own country. This created the conditions for the defeat of the Tibetan army.

As long as the Flying Tiger Army cut off the grain route, the Tibetan army will inevitably withdraw. When the time came, the Tang Army and Xue Rengui's troops, who were hiding in the Tuyuhun army, made a sudden counterattack.

There is a possibility that the Tibetan army will collapse.

These tactics are interlinked, and they really require strategic vision. His Royal Highness King Liang is handsome. ”

Li Chengqian and the others were very depressed when they heard this: "When did this three evils become handsome again?" ”
