He said to Li Bing: "I will leave 20,000 troops for you, on the one hand, to protect Daying and Cangcheng, on the other hand, you have to intercept the actions of the enemy army in Yazhou City, if you can't intercept it, you must notify me immediately, there must be no mistake!" ”

"Obey the order!"

Guo Song nodded, and said to Pei Xin: "You can lead five thousand cavalry as the vanguard, your task is to harass the reinforcements, let them rest badly, increase their fatigue, remember one point, and do not directly engage the enemy, this is not your business." ”

Pei Xin bowed and saluted, "I understand my humble duties!" ”

Guo Song took out the order arrow and gave it to him, "You can prepare now, set off at night!" ”

Pei Xin gave a salute, took the arrow and went out.

Guo Song explained a few more words to Li Bing, and Li Bing was also ordered to prepare.

At this time, only Wang Yu was left in the big tent.

Guo Song smiled slightly: "Wang Yuanjun doesn't have to be annoyed, I know very well in my heart that ambushing the enemy army is indeed the best strategy, after all, the Tubo soldiers are human beings and not gods, if our ambush is combined with iron fire and thunder, I believe that the Tubo reinforcements will be defeated in a battle." ”

Wang Yu was stunned, "Since His Highness also admits that the ambush is effective, why do you still have to fight the enemy army in the field?" Is it really to sharpen the soldiers? ”

Guo Song shook his head, "Sharpening soldiers is one thing, but it's not the main reason. ”

"I would like to listen to you!"

Guo Song walked to the door of the tent with his hands down, looked at the famous mountain county town reflected by the gorgeous sunset, and said slowly: "I have been thinking about it for the past few days, why Tubo has repeatedly attacked the Tang Dynasty and been repeatedly defeated, but he has always refused to give up, and he has repeatedly provoked him, I have figured it out, in the final analysis, it is a sentence, 'fear of power and not fear of virtue', they must be beaten painfully, beaten to the point of complete fear, they will remember the lesson, and dare not make mistakes easily." ”

Wang Yu pondered and said, "I understand His Highness's words, but what does this have to do with the way of fighting?" ”

"It has something to do with it, exactly!"

Guo Song turned around and said: "If the Tubo army is defeated by an ambush, they will be lucky to think that it is just an accident, as long as they are careful and do not be ambushed by the enemy again, then they will not repeat the mistakes of the past, they will always think that in the wilderness battle, they will definitely defeat us, so if they want to completely extinguish their luck, then they must fight with them in the wilderness, and then make them collapse in the most ruthless and brutal way, completely frightened, and make them realize that they can never defeat the Tang Dynasty, and then what?" ”

"And then what?" Wang Yu didn't understand the turning point of King Jin's last sentence.

Guo Song smiled faintly, "Then the Tubo nobles will realize that Tianzhu is a soft persimmon, and the national policy of Tubo will be turned, and then a new balance will be formed, which will be maintained for decades, and Tubo will break out due to civil strife and division due to uneven interests, and a new balance will be formed after a hundred years of civil war, and basically no invasion of the Tang Dynasty will be considered." ”

"I understand what His Royal Highness means, Tubo is still in a state of instability, if Tubo annexes Bashu, they will stabilize on the basis of invading the Tang Dynasty and obtaining huge benefits, forming a balance, and will continue to invade the Tang Dynasty in the future to maintain this balance.

And our purpose is to push the Tubo to turn and stabilize them on the basis of the invasion of Tianzhu, then they must rely on constantly sucking blood from Tianzhu to maintain this balance, and the Tangbo border will enter a long-term stability. ”

Guo Song smiled and said, "It seems that Wang Zhijun has completely comprehended!" ”

Wang Yu let out a long sigh, "Your Highness's vision is very long-term, and it is very human!" ”

Guo Song sat down and said: "Actually, I summoned Wang Zhijun from Hebei, the main purpose is to hope that Wang Zhijun will coordinate the entire military affairs, logistics supply, dry food preparation, material allocation, people's transfer, etc., this is what you are best at, I want to consider the overall situation, the decisive battle of the army, I have no energy and no time to think about trivial military affairs, so this time to fight with Tubo, it doesn't matter if you are not familiar with Tubo, I need you to play Xiao He, not Zhang Liang." ”

Wang Yu nodded silently, King Jin's words made him come out of the regret just now, and his heart suddenly brightened, and he said happily: "Thank you Your Highness for your enlightenment, my humble heart is much more comfortable." ”

Guo Song smiled again: "I shipped a batch of trebuchet parts from Chang'an, it is estimated that it will arrive today and tomorrow, I hope you will complete the installation as soon as possible!" ”

"The lowly duty will definitely be completed on time!"

........

In the afternoon of the next day, Guo Song set off with 45,000 cavalry, and last night, Pei Xin had already led 5,000 cavalry to set off first.

On the day when the king of Jin led the main force to leave, Li Bing also began to act, he removed all the tents in the camp and sent them to Cangcheng, making the Tang army camp an empty camp, and 5,000 troops remained in Cangcheng.

Li Bing led 10,000 troops into Pingyang Town, which is located between Cangcheng and Yazhou City, and Li Bing's intention is also obvious, attacking and retreating.

In addition, Li Bing sent his general Zhang Lingyun to lead 5,000 cavalry to be stationed outside Yazhou City to monitor every move of the Yazhou Tubo army.

20,000 Tibetan reinforcements marched all the way to the east, day and night, this evening, the army stopped and camped in an open place, where the field of vision is relatively wide, you can see the snow-capped mountains in the distance, under the snow line is an endless forest, which extends to several miles away, the north and south are also forests, they are just in a meadow in the middle of the forest.

The Tibetan soldiers were busy, some building fires to make food, and some setting up small low tents.

The main general of the reinforcements is called Lun Cheek Fever, is the confidant of the great minister Shang Jiezan, this time the upper echelons of Tubo are very firm in the will to fight for Bashu, they want to completely occupy and consolidate the root base of Yazhou, and then gradually annex to the south and east, and occupy Bashu in ten years, so Tubo has made a bloody capital and sent 50,000 troops to Yazhou, accounting for 30% of the entire Tubo army.

He was also afraid of being ambushed by the Tang army, so he sent hundreds of spies around the camp after stationing.

After eating and drinking, the Tibetan soldiers who had marched for a day were exhausted and lay down to sleep, and many people snored as soon as they lay down.

But less than an hour after falling asleep, a rapid horn suddenly sounded from the southeast, "Woo-"

This was the alarm of the discovery of the enemy's situation, and the soldiers stood up in fright, and the soldiers did not care about sleepiness, and got up one after another, and even the yak lying on the grass opened its eyes.

The soldiers gathered in a hurry, but there was no enemy attack, and at this time, several outlying patrolmen galloped back on horseback.

On the cheeks asked dissatisfiedly, "What's the matter?" ”

A patrol leader clenched his fists and said: "We found a brigade of Tang Army cavalry, there are thousands of people!" ”

"What about them?"

"They're heading west, and their whereabouts are unknown!"

"Didn't you send someone to follow you?" On cheek fever, he asked again.

"Two brothers were sent to follow them, but there is no reply."

On the cheek enthusiasm felt bad in his heart, I was afraid that the patrol sent by the enemy would be killed.

Now that he found the cavalry of the Tang Army, he began to feel uneasy in his heart, and immediately ordered left and right: "Pass the order, the first battalion and the second battalion take turns to sleep, and you must be vigilant tonight." ”

The order was passed down, and some of the soldiers continued to sleep, while the other half had no chance to sleep, so they had to endure sleepiness and torment.

But in less than half an hour, there was a sudden sound of drums and countless rockets from the south, and the soldiers who had just fallen asleep jumped up in fright, and shouted on their cheeks: "The army is assembled!" ”

20,000 soldiers of the Tibetan army quickly assembled, but the Tang army suddenly fell silent again.

A senior general whispered to the hot cheeks: "This should be the Tang Army deliberately disturbing us?" You can ignore them. ”

On cheek fever shook his head, "Feint a few more times, and when we are completely relaxed, they will really attack, we can't be careless." ”

"But the soldiers can't sleep, and their bodies will be very sleepy."

"It's okay, rest after dawn!"

This time, all the Tibetan soldiers could not sleep, and sat on the ground to maintain their formation, and many soldiers were napping.

But more than half an hour later, the sound of horses' hooves in the north was loud, and the shouts of killing shook the sky, and hundreds of patrol posts and the Tang army fought.

The soldiers of the Tubo army formed a team again, went to the north to kill, and rushed to the place of the fight, only to see dozens of corpses on the ground, all of which were Tubo patrol posts, and the Tang army disappeared again.

All night, the Tibetan soldiers spent the whole night in fear, and finally stayed up until dawn, and ordered the soldiers to rest for half a day, and set off after lunch.

But even during the day, they couldn't sleep, and the soldiers had rested for less than an hour, when a group of thousands of Tang cavalry suddenly came out of the woods to the north.
