Liu He's expedition to Tibet this time deliberately created Wang Yanzhang's murderous reputation, and the main purpose was actually to let Wang Yanzhang be the main general of the future conquest of Tibet, and lead the army to destroy Tibet.

Through interrogation of the captives, Liu He learned that there are only 20,000 or 30,000 remnants in the Tubo army, and 20,000 of them are under the personal leadership of Songtsen Gampo to compete with Lu Xun in the southwest region.

Therefore, after conquering Subi, Liu He appointed Wang Yanzhang as the general of the army, leading 5,000 elite soldiers, taking advantage of the weakness to enter and take some Luo.

Because Wang Yanzhang had the problem of not knowing the way, in order to ensure the victory of the army, Liu He also sent several experienced guides, and also equipped them with a compass.

Now proficient in using the compass is almost a basic skill that Liu He's guides must master, and even so, Liu He was completely relieved after they demonstrated the skills of using the compass.

"Tubo basically has no resistance now, I don't have to worry about this, the majority of soldiers have been fighting for months, they have already been physically and mentally exhausted, this time after the class teacher returns to the court, he must have a good rest, and when the rest is over, I will think about other battlefields, hehe, now there is Kong Ming in the north, although Genghis Khan is powerful, but in front of the old Cheng Zheng Kong Ming can not make much waves, and there is Zhao Yun in the Liaodong region, this man is both civil and military, and there is no defeat in his life, I am also very relieved, Zhou Gongjin, one of the top commanders of our army, is fighting against the Japanese country in the southeast region, and Zhou Yu has the skills of being good at water warfare and the god of fire, even if he can't be defeated, he can definitely remain undefeated, so although it seems that the border is constantly on fire, but there is no crisis anywhere, since this is the case, then I will first take a good rest and recuperate, and then wait for the war in the western Xinjiang to be completely over, draw forces from here, and then gather a large army to eliminate the alien forces in one fell swoop, and completely end the war. ”

Liu He had already made plans in his heart, so he didn't have any worries at all, but ordered the army to advance slowly while observing and recording the terrain.

And Wang Yanzhang led the army to advance at a high speed, because there was a guide around him, and Liu He's warning was in his ears, Wang Yanzhang did not dare not listen, there was nothing wrong with this road, it only took a month, and he galloped for 2,000 miles and came to the city of Luo.

At this time, the young patriarch of Tubo, Mangsong Mangzan, had already received the news of the defeat of the army in Subi, but because the number of people who could fight in the city was extremely limited, and the old, weak, sick and disabled were all combined, it was only 3,000 people, and it was impossible to be the elite opponent of the Han who could conquer and fight.

Mang Songtsan had actually urged the Tubo patriarch Songtsan Gampo to lead the army back, but the Tubo army was now in a state of stalemate with Lu Xun's soldiers, and it was difficult to get out for a while, and it was even as far away as four thousand miles away from Luo, even if he could get out immediately, it was estimated that it would take two months to return to Luo, and when his army returned, it was estimated that the daylily would be cold.

"For the sake of today's plan, only to resist desperately, our army to hold on to the city fortress, and perhaps there is still hope to hold on to the return of the army of my father (in history Mangsong Mangtsen is the grandson of Songtsen Gampo), if you go out of the city to fight, it is estimated that it will not last for a day, so all the people must obey my orders, without my orders, no one is allowed to go out of the city to fight without permission, otherwise, although the victory is also a crime."

Mangsong Mangzan thought about it again and again, and finally made such a decision.

However, this decision was actually useless at all, because even if he didn't say anything, absolutely no one in Tubo was willing to go out of the city to fight, and everyone knew that in the face of the attack of the Han Dynasty's army, there was no difference between fighting out of the city and committing suicide.

So all the soldiers guarded the city with anxiety in their hearts, hoping that the Han army would not arrive so early, and even hoped that the Han army would not come here.

Even if you don't count the military losses in Yizhou, this time the defeat of the Garqinling army alone has caused heavy losses to the Tubo people, and the population has plummeted, and it is estimated that even if it takes another twenty years, it will be difficult to return to the grand situation before the defeat.

Originally, Mangsong Mangzan still had a trace of confidence in resisting the arrival of the Han army, especially when they heard that the Han army was only 5,000 people this time, they were full of hope, after all, the gap between the forces of the two sides was not very large, and the total number of troops on the besieging side was less than twice the total number of troops on the defending side.

However, when they heard who the commander of the Han army was, they all gasped, and the only trace of resistance in their hearts was shattered.

"What do you say? It turned out to be Wang Yanzhang, the son of Wang Man, who led the army to arrive? How is he? Why him? When Mangsong Mangzan heard the news, he immediately felt cold from the top of his head to the soles of his feet, because now Wang Yanzhang's murderous reputation has already spread among the Tubo Shishu, almost everyone knows that this person is simply a big devil who kills people without blinking, but he is also brave and invincible, even the most brave Garqin Mausoleum in Tubo can't walk Sanhe under his hands, such a warrior comes to Luo, isn't this a great misfortune for the Tubo army and people?

"Wang Manzi is here, what else do we have to say? Needless to say, even Wang Manzi alone can kill all the guards in our city, not to mention that he still has 5,000 elite soldiers under his command, this time we have no hope at all, everyone, give up resistance and flee on your own. ”

The word "resistance" could not be uttered in Mangsong Mangzan's mouth at all, and even if he said it, no one would abide by it at all, so instead of saying it, it was better not to say it, and just announce his escape.

"Young master, let's go, the enemy army is invincible, that Wang Manzi can kill the prince of Gar Qinling with one shot, this person's martial arts are also the top in my Tubo, but they are still killed instantly, we are not even as good as the prince of Qinling, and we can't resist it, Gongzi, you are the young master of my Tubo, bearing the future and hope of Tubo, you can't give up easily, they Han people have a saying, called stay in the green mountains without worrying about no firewood, as long as the young master keeps his useful body, it may not be impossible to kill back in the future."

Mangsong Mangzan was afraid that he would be impulsive, so he hurriedly persuaded him with words.

In fact, where does Mangsong Mangzan need to be persuaded? He decided to flee as soon as possible, so he didn't dare to face Wang Yanzhang at all, hurriedly took his own soldiers out of the palace gate, rode on a horse, and killed him in the direction of the west city gate, but he heard that Wang Yanzhang is now at the east city gate, as long as Wang Yanzhang is not there, he is completely confident that he can break through.
