Guo Song led 20,000 cavalry to run for two days and two nights, and finally arrived at the camp in Mingshan County, and his deputy general Li Bing also came back a few days ago, and the Tang army in the entire Mingshan County had a strength of 70,000 people, all cavalry.

Their biggest problem is still supply, 10,000 camels have been going back and forth between Chengdu and Mingshan County, to transport grain and grass, and to transport military supplies, resulting in a relatively tight supply of military food, the fleet of good eunuch groups has been brought back to Chengdu, so that they can supply from the waterway, although they have to transfer by the camel caravan, but this distance is much closer.

It was already midnight, Guo Song couldn't care about his physical exhaustion, went back to the Chinese army tent and drank tea, and summoned Wang Yu, Pei Xin, Li Bing and Zhang Yun.

During Guo Song's absence from Mingshan, Pei Xin and Wang Yu temporarily commanded the army, and they knew the situation better.

"Back to Your Highness, four days ago, our team of scouts captured two Tubo soldiers and a servant, but the Tubo soldiers were very strong, and the two committed suicide by chewing their tongues on the way, this servant was a little timid, and confessed under our coercion, these two Tubo soldiers were reporting reinforcements, but the confessor was a servant after all, and he didn't know much information, how many reinforcements there were, and how far away from here he didn't know."

Guo Song pondered and asked, "Isn't there a written letter?" ”

Pei Xin shook his head, "We searched again and again, but we didn't find any written letters. ”

Wang Yu next to him added: "As far as the lowly knows, the scout team chased the two messengers for more than fifty miles before catching them, and it is estimated that the letters were destroyed by them in the process, and the lowly officials also felt that there should be written letters." ”

Guo Song nodded, since he chased for more than fifty miles before he caught it, the letter must have been destroyed, torn and swallowed, or torn and thrown away, it is unknown.

He took a few steps with his hands in his hands, then turned back to Zhang Yun and said, "I think it is best to annihilate this army a hundred miles away from Yazhou City, so the scouts have to explore farther, and I will leave this task to the scout battalion." ”

Zhang Yun bowed and said, "Please rest assured, Your Highness, the humble post must be arranged!" ”

At this time, the soldiers reported outside the tent, "Your Highness, General Zhou has sent a subordinate from the city. ”

Guo Song was overjoyed and hurriedly said, "Bring him in quickly!" ”

Not long after, the soldier brought in a thin man, Zhang Yun smiled dumbly, "Monkey, why are you?" ”

This soldier is the subordinate who explored the cave with Zhou Fei, his name is Shen Yaozu, only twenty-five or six years old, a native of Chencang County, Guanzhong, from a famous martial arts family, he began to practice martial arts at the age of three because he practiced martial arts too early, and as a result, his development was affected, resulting in his thin and small body, with sharp beaks and monkey gills, so he has a monkey's nickname.

He participated in the recruitment of the scout battalion six years ago, although his physical condition was not qualified, but Zhang Yun found that he was extremely light, so he was admitted exceptionally, and he made meritorious contributions in the battles of attacking Guanzhong and Hebei, Zhang Yun promoted him twice, and now he is a scout brigade commander.

Shen Yaozu hurriedly saluted Zhang Yun, and knelt down on one knee to give a big salute to Guo Song, the king of Jin, "Scout battalion commander Shen Yaozu see His Royal Highness the King of Jin!" ”

Guo Song smiled slightly: "It seems that Shen Lushuai is very famous in the scout camp!" ”

Zhang Yun stepped forward and introduced with a smile: "We all call him Shen Monkey, he has excellent skills, and he can climb the city directly, he should just come out of the city wall, I'm not wrong!" ”

"The commander is not wrong, he came out of the eastern city wall and took advantage of the loophole of a team of patrol posts."

"Shen Lushuai has worked hard!" Guo Song said approvingly.

Shen Yaozu was moved in his heart, and hurriedly said: "I have to rush back overnight, tomorrow when the Tubo army takes the roll call, I will find that there is one less person, and the laborers of the team will be killed, and none of the brothers will survive." ”

"That's a long story short!"

Shen Yaozu immediately told Zhou Fei about the discovery of the hole in the city wall, Guo Song and the others exchanged a look, and this discovery finally revealed a mystery in their hearts, how did the Tubo army capture Yazhou City?

"How's the cave going?" Guo Song asked again.

"We have restored to the original state, in fact, the Tubo army is filled in with stones, with a little more manpower, it can be cleaned in half an hour, we are afraid that the Tubo soldiers will find out, and there is no trace left."

Guo Song walked a few steps with his hand and said: "This loophole Tubo people will not be negligent, you are just lucky not to meet anyone, you may encounter it next time, tell General Zhou, don't be careless!" ”

"Obey the order!"

Shen Yaozu took out a roll of cloth from his bosom and presented it to Guo Song, "This is a map of the garrison in the city drawn by General Zhou, please come over." ”

This map is exactly what Guo Song needs, he was in good spirits, and hurriedly took it and opened the map, the location of the labor camp, the location of the camp of the Tubo army, and the deployment of the Tubo army were all clearly marked.

It is worthy of the scout's map, concise and complete, Guo Song handed the map to Wang Yu and asked him to arrange to join the army and redraw it.

Guo Song said to Shen Yaozu again: "You go back and tell General Zhou that we are likely to carry out an iron fire and thunder attack, you must pay attention to safety, and then on the third night after the iron fire and thunder stop, at the third watch, we will attack Xicheng, and there will be nine gunpowder arrows at about one watch." ”

"Humble, remember!"

Guo Song immediately asked his soldiers to take Shen Yaozu down for a full meal, and then sent him out of the camp.

At this time, Li Bing saw that His Royal Highness the King of Jin's eyes were bloodshot, and he should have not slept for two nights, so he said, "Your Highness, rest!" If there is anything, we will discuss it again tomorrow. ”

Guo Song nodded, he was really a little sleepy.

..........

In the endless mountains and forests, a 20,000-strong Tibetan reinforcement army was rushing in the direction of Yazhou, this is 20,000 infantry, and thousands of yaks, which carry the rations of the soldiers.

The place where the Tubo army is located is a village called Songcheng, which belongs to the Tubo boundary, and crosses a mountain to enter the Yazhou boundary, which is not far from the Jinsha River, and the Jinsha River roars in the mountain stream, the sound is like a huge thunder, and it can be heard clearly dozens of miles away.

This is, on the hill ten miles away, a group of Tang Army scouts appeared, consisting of ten Tang Army scout cavalry and a guide.

They found the Tibetan reinforcements in an hour, but they needed to determine the number of the other party, on the hill, the scout brigade commander determined the number and equipment of the Tibetans, about 20,000 people, the equipment was average, leather armor, shields and short swords, he immediately turned his horse and led his men to run towards the city of Huiye, which was more than ten miles away.

Huiye City is today's Kangding, under the jurisdiction of Yazhou, is a small border city, the residents are basically Qiang people, there are also some Tang Dynasty merchants who came here to do business, and the letter eagle of the Tang army scouts is in the small city of Huiye.

Soon, a letter eagle soared into the air, circled in the air a few times, and flew towards the camp of Mingshan County, which was three hundred miles away.......

The Tang army camp in Mingshan County was particularly lively, 10,000 camels and 3,000 ox carts loaded with grain and grass arrived at the camp, they came from Meizhou, and the ox carts were also requisitioned from Meizhou on the spot, and the arrival of the grain team greatly relieved the grain and grass tension of the Tang army.

Mingshan County has become the Tang Army's Cangcheng, there are 5,000 troops dedicated to guarding Cangcheng, Cangcheng moat is lined up outside the moat, the ox cart driver has gone to rest, replaced by Tang Army soldiers, even so, entering Cangcheng will still be very strict check the military license plate and password, Guo Song in the safety of materials and food, almost invulnerable, do not give the enemy any chance.

They had to guard against not only the Tubo army, but also the destruction of other forces, which was also the main reason why Guo Song made the county seat of Mingshan a cangcheng.

At this time, in the big tent of the Chinese army, Guo Song urgently summoned Li Bing, Pei Xin and Wang Yu.

"I just received an eagle letter from the scouts of Huiye City, and they found the Tibetan reinforcements, about 20,000 people, mainly infantry, with a small number of cavalry, and they are still more than two hundred miles away from us."

Guo Song unfolded a map, the red line on the map is the route of the Tubo army, he pointed to a black dot on the map and said: "This is Huiye City, the scouts found the Tubo reinforcements in the morning, the march lasted for most of the day, the Tubo army probably walked about forty or fifty miles, and the location should be here." ”

Guo Song marked a point on the map again and said to everyone: "This time I am considering using the Tubo army to sharpen the army, what is everyone's opinion?" ”

Wang Yu smiled and said, "Why doesn't Your Highness consider using the strategy of ambush?" I see that this area is lush with forests, which is very suitable for ambushes, don't you think about it, Your Highness? ”

Pei Xin next to him said: "Sir doesn't know, if it is Zhu Jun's army or Li Na's army, you can use the method of ambush, but the Tubo army is different, the Tubo army is good at assembling operations, once ambushed, they will not escape, but will quickly assemble into a group, extremely tough, and the cavalry can not be used in a narrow area, although ambush is a good strategy." But it is not the best way for the Tibetan army. ”

Guo Song glanced at Pei Xin approvingly, and the last sentence summed it up well.

Wang Yu was a little ashamed, although he held back his strength to come up with a plan, but he was really not familiar with the Tubo army, and he felt a sense of frustration in his heart, so he was silent.

"What does General Lee think?" Guo Song asked Li Bing again.

Li Bing groaned and said: "We don't know if the Tubo army in Yazhou City has received a message from the flying eagle, if the Tubo army in Yazhou City gets the news, they will inevitably find out about our attempt, so while we are fighting the Tubo reinforcements, we must also prevent the sneak attack of the Tubo army in Yazhou City." ”

Guo Song nodded, and the combat ideas in his mind gradually became clear.
