As he spoke, the strategist Hu Tu slowly walked into the big tent, and the two guards followed closely behind, carrying a wide cowhide map into the tent.

"Brother Oman, this is a map of the border situation drawn by our scouts, can you point out where the secret passage is for us?" Xiongnu Shan Yu walked to the map and pointed to the simple and not detailed cowhide map.

Aman bowed when he heard this, and then walked briskly to the side of the map, and made a slight gesture on the map. "This is it!" Aman pointed to the location of the Burial Valley with excitement and said with an unchanged expression.

"What's the topography like? How much is there a garrison of the Zhao army? Shan Yu stared at the position of Aman's finger, his eyes couldn't help but turn a few times, and he continued to ask with concern.

"Back to the single Yu, the mountain here is not steep, and the strange rocks are craggy, easy to climb, close to Zhao people to and from the grassland Zhao realm, often take shortcuts here, and gradually form several walkable trails over the decades. There is the Great Wall of Zhao Army on the top of the mountain, it is not very high, more than 5,000 permanent soldiers, this time Li Mu adjusted the deployment, only more than 3,000 soldiers remained here. ”

"It seems that this retainer has been near?" After measuring the map with his hand, Yi Chi said in an uncertain tone: "The merchants of the Zhao Kingdom who smuggled in the past used to trade goods with me here. ”

"And such things, come and talk about it for me!" Shan Yu asked Yi Chi with interest: "Let's sum it up and see if this place is really suitable as a place for my army to attack!" ”

Yi Chi obliquely claimed the promise, and then talked eloquently: "As we all know, when the former Yanmen County Shouyan Ju was in power, the smuggling operations of the Zhaojing business brigade were quite rampant, and at the height of the time, people said that 'the Great Wall of 100 miles, there are trade goods everywhere"! At that time, I was ordered by Shan Yu to personally go south to trade materials, and the place where the merchants of Zhao agreed to meet was here, and the name of its countryside was called 'Tibetan Soldier Valley'! ”

After a pause and careful recollection, Yi Chi continued to narrate: "According to my impression, although this place is surrounded by mountains on three sides, the mountains are not high and the slopes are not steep, although there are Great Walls built on the top of the mountains, but the terrain is narrow inside and wide and the area is open, and people can gallop in it. At that time, the dozens of tents set up by the merchants of the Zhao State only occupied a corner of the southeast direction, while a large number of grassland tribes were stationed in the southwest corner to wait in turn! ”

Taking a deep breath, Yi Chixian continued: "According to the merchants of Zhao State at that time, for decades, the local villagers have taken shortcuts to and from the interior of the grassland, so they have artificially stepped on several small roads on the hillside. Most of these trails are irregular, rocky, and in some places there is only a place to step on, but the difference between the vegetation and vegetation is obvious. The generals of the Zhao army guarding the wall did not restrain the practices of the local people, and were even happy to see it happen and enjoy its benefits. Whenever a merchant traveler passed through in order to evade customs duties, the guards would often collect a certain amount of tolls and let them go, and if the merchants were willing to pay an extra sum, the defenders would even be willing to carry the goods for them. ”

"In your opinion, can this place be attacked? Can the army pass through this place? Shan Yu Wenyan asked with concern.

"According to the opinion of the last general, it is feasible to invade Zhao from this place. As long as our army can quickly defeat the defenders of the 3,000 Great Wall, occupy this section of the Great Wall of the Zhao army, and then quickly pave several smooth roads with earth and rocks for the passage of large army chariots and horses. "Yi Chi oblique is a single in detail to break down.

"In such an important place on the frontier, Li Mu only arranged 3,000 defenders, could it be Li Mu's suspicious strategy, and he needs to beware of the Zhao army's ambush!" Strategist Hu Tu said with a little worry: "Shan Yu, do you want to send someone to investigate first!" ”

"This place is narrow inside and wide outside, and the valley mouth is about dozens of miles wide, and it is almost impossible to block it. If there is an ambush in the valley of the Zhao army, our army can calmly retreat from the valley mouth! Igbla retorted to Hutu and added.

"You're right, but Hutu's words are also reasonable!" Shan Yu stared at Yi Chi's slanted face, and said in a cautious tone: "It is necessary to send people to the Valley of the Hidden Soldiers to investigate, and it is also necessary to dig out the mouths of more prisoners to obtain more information!" ”

Aman's expression darkened when he heard this, and then he quickly returned to calm, and said in a cold tone: "This is also the proper meaning of the question, the criminal minister is willing to lead the scout to investigate!" ”

Shan Yu looked at Aman, patted him on the shoulder and explained, "I don't want to doubt you, but I want to be foolproof." ”

"The minister understands!" Aman bowed again.

—————————————————————————————————————

On August 11, the seventh year of King Zhao Xiaocheng, Shan Yu once again obtained information on the deployment of the Zhao army from the mouth of the captive: the 20,000 Zhao troops led by Li Mu were divided into two parts, stationed in Datongsai and Yuanyangsai respectively, and this news just confirmed the truth of what Oman said.

On the twelfth, Li Mu, the county guard of Yanmen County, sent an envoy to the Xiongnu camp, and the envoy was tenacious and inward, and several times shouted the crimes of the Xiongnu for destroying peace, and his behavior further strengthened the judgment of the emptiness of the Zhao army in Shan Yu's heart. Later, Shan Yu decisively detained the Zhao envoy, but for some reason, Zhao Jun was silent and did not reply, as if the envoy had never happened. Shan Yu confirmed the conjecture of the Zhao army's strong and middle-class cadres with his actions to the generals under his command, and the Huns were all impressed for a while!

On the 13th, a few days ago, the outpost who had left the camp a few days ago and secretly went to the Tibetan Soldier Valley with Oman to investigate, returned with the news of the emptiness of the Great Wall in the Tibetan Soldier Valley and a brief topographical map of the surrounding area. According to the sentry detectives, there are 3,000 soldiers on the Great Wall of the Zhao Army in the Tibetan Soldier Valley section, of which no more than 1,000 can be called elites, and the ground is not high and easy to climb, if more than 10,000 people attack at the same time, they can fall in one fell swoop. As for the topographical map of the surrounding area, it laid the foundation for the deployment of troops alone and the determination of the method of attack.

On the 14th, Shan Yu convened all the generals in the big tent of the Chinese army, explained the method of deployment and the place of battle with his subordinates, and clarified the tasks of each general and the troops he led. In addition, Shan Yu also agreed with the generals on the decree of military warfare: those who are ineffective in combat will be beheaded, those who escape from the battle will be beheaded, and those who disobey the order will be beheaded! All the armies were solemn when they heard the order, each general went deep into the army, all departments urgently prepared for war, and all armies were in an orderly manner. In one day and one night, the sword was sheathed, the bow was wound, the men and horses were fed, and the battle between Zhao and Hungary was about to break out.

In the mid-autumn of the seventh year of King Zhao Xiaocheng, the sky was clear, the sky was cloudless, and the cold breeze blew through the Xiongnu Shan Yu's Daxu, making a rustling sound. At the end of the day, the Xiongnu went through the grievances between the Zhao army and the Xiongnu in the camp, and then swore to attack, and a wizard divined and said: "Daji"!
