In early September, the Xiongnu changed internally, and when the Xiongnu was in the west, the upper county adjacent to Henan, Qin Shi Huang's imperial drive had reached Gaonu County......

Gaonu is the revolutionary holy land of Yan'an in later generations, but at this moment, there is no pagoda on Gaonu Mountain, only a high rammed earth watchtower stands on the top of the mountain, overlooking the whole city. Qin Shi Huang traveled on the mountain, accompanied by Li Si, the court captain, Feng Jing, the county lieutenant of Shangjun, etc., Li Si was well-read and strong, and gave Qin Shi Huang a detailed introduction to the situation here:

"Although Shangjun is the county government of Fushi, but the most hukou, the largest city, and the number of high slaves, a hundred years ago, Shangjun was still Wei, and this is the place where the boats and cars come together."

Shangjun was originally the land of Bai Zhai, at the turn of the Spring and Autumn Period and the Warring States Period, Wei Wenhou made Li Kui and Wu Qi subdue Bai Zhai and set up Shangjun, and then maintained a hundred years of rule here.

However, as Qin became stronger and stronger, Shangjun west of the river could not be defended, and in the 7th year of King Hui of Qin, the Qin army defeated the Wei army in Diaoyin, not far south of Gaonu, captured the Wei general Long Jia, and beheaded 80,000. After this war, the Wei state became increasingly decaying, and the following year the West River, which had been contested for half a century, was ceded to Qin, and in the 10th year of King Hui of Qin, even the fifteen counties of Shangjun were also surrendered, and the riverside land west of the river was all under Qin...... Since then, the trend of Guanzhong has been formally established.

"Your Majesty is the second monarch to come to Shangjun to patrol the county."

Feng Jing was also very good at talking, and pointed to the soldiers of the southern county of Shangjun who were under the mountain to be inspected by Qin Shi Huang and said: "When the soldiers heard this, they were ecstatic!" ”

The autumn harvest has ended, taking advantage of the slack of farming, in the border county, every year at the end of August, early September will assemble the guards, soldiers, so that they are familiar with the order of the army, practice bow and crossbow swordsmanship, Shangjun and the Rong people, the Xiongnu adjacent, if the sword is not sharpened fast enough, I am afraid that it will be invaded.

Looking at the light cars, knights, and material officers who were shouting a tsunami down the mountain, Qin Shi Huang nodded with satisfaction and asked Feng Jingdao: "How many soldiers can be conscripted in Shangjun?" ”

This is the duty of the county lieutenant, and Feng Jing naturally replied fluently: "There are fifteen counties in Shangjun, 60,000 households, more than 300,000 mouths, and 20,000 county soldiers can be levied." Plus Bai Zhai steps and rides, about 25,000! ”

This is all the troops that Shangjun can dispatch, Qin Shi Huang remembers, Li Xin said that Longxi can levy 20,000 troops, and the Beidi County, where Heifu is located, has a small population, and there are only seven counties under its jurisdiction, so it can only levy 15,000 people......

In addition to the Yunzhong, Yanmen, and Daijun coordinated by Meng Tian, 40,000 troops can be dispatched, and several border counties will have 100,000 people, and the internal history will dispatch another 50,000, plus the 150,000 people raised by the whole country, and 300,000 people can be gathered to use force against the Xiongnu!

After a trip to the north, facing the ruins left by King Wuling of Zhao, and looking at the Xiongnu who had a strong military force outside the Saiwai and posed a faint threat to the northern frontier of their empire, Qin Shi Huang had set a plan: the war is next year!

If possible, the emperor would like to go to war this autumn and winter.

But Qin Shi Huang also knew that this was no less than a bitter battle to destroy Wei and Yan. The soldiers and horses will not move the grain and grass first, and the grain that can supply 300,000 people will not be able to reach the front line until next year, and the people from the interior will not be able to embark on the journey until the spring ploughing is completed next year.

Therefore, what can be done now is only to urge the border counties to step up training, be ready to fight at any time, and at the same time actively probe the internal intelligence of the Xiongnu.

In this regard, Feng Jing thought that he had done a fruitful job, so he confidently reported to Qin Shi Huang about his infiltration of Lin Hu for more than half a year......

"Lin Hu is also known as Lin Ren, Dan Lin, tens of thousands of his clan, are scattered in the mountains and forests outside the Saiwai, hunting as a business. Decades ago, Zhao's father Hu Fu rode and shot, closed the building annoying, Lin Hu, Lin Huchen belonged to Zhao, after the Huns gradually strengthened, and then voted for the Huns, the Huns took Lin Hu as the 'Lin slave', and every year Lin Hu Jun contributed prey and timber to the unknown. ”

"In this way, Lin Hu and the others are just forced by the Xiongnu, not loyal submission?" Li Si heard what he said, all he thought.

Feng Jingdao: "However, Yan Yan, Lin Hu, Lou Fu, and Bai Yang are just like the kings of Yu Yue and Gan Yue, who were attached to Chu in the past, although they are all Hu people, they each have their own rulers. ”

Li Si slapped his palm: "In this case, if Your Majesty wants to attack the Huns, these parts may also be used by me!" ”

"That's exactly what the county guards and ministers are going to do!"

Feng Jing said that Shangjun Shouqiang took advantage of his advantage as a Qiang person, and used the Qiang people and Bai Zhai people as messengers, went out of the fortress several times, went deep into Lin Hu, found Lin Hu Jun, moved him with affection, and persuaded him to surrender to Qin.

Lin Hu Jun has moved, as a small tribe between several major forces, they follow the principle of only the strong, Zhao Guoqiang will descend to Zhao, and the Xiongnu will descend to Hu, and now the Qin Dynasty is powerful, it seems that the time has come to change the court......

But because there was a proton detained in the Shan Yu royal court, Lin Hujun did not rashly agree, only promised that he would never dare to be the enemy of the powerful Qin army, and the implication was that when the Qin army crossed the border, he could turn a blind eye.

Therefore, Feng Jing believes that as long as he follows the old routine of Qin's annihilation of the Six Kingdoms, sends envoys, bribes the four departments, and sends people to give Lin Hujun some benefits, next year Qin will go to war with the Xiongnu, and Lin Hu can be subdued without a fight.

"The Xiongnu are known as 100,000 people who control the strings, in fact, the vassal tribes are also included, if you lose Yunyan, Lin Hu, Lou Fu, and White Aries, the Huns have lost one-third of their military strength!"

When Feng Jing was presenting his battle strategy to Qin Shi Huang, two urgent reports arrived at the same time, one from the Great Wall border outpost and delivered to Feng Jing, and the other from Beidi County......

Hearing that it was the military newspaper of Beidi County, Qin Shi Huang immediately asked people to open the seal and check it by himself.

The subordinates didn't dare to disturb, so they could only take a look on the side to see what news came from the Shangjun Border Fortress......

"It's Lin Hujun!"

Feng Jing was very surprised, and after quickly looking at the two lines, he said to Li Si: "Lin Hujun said that the Xiongnu Shan Yu suddenly expelled his son Mao Dun, and ordered the Gudu Marquis to be divided into the four departments of Yan Yan, Lin Hu, Lou Fu, and Bai Yang, and asked the four monarchs to come to Shan Yuting in person to participate in the October meeting!" ”

This summons is extraordinary, Lin Hujun and Shangjun secretly corresponded, there are ghosts in his heart, of course he didn't dare to go, after gritting his teeth, he felt that Lin Hu was sheltered by mountains and forests, and there were buildings in the north, and the cavalry of the Huns Shan Yu could not quickly kill him, so he couldn't take care of the eldest son who was still in Toumancheng as a hostage, so he simply asked Feng Jing to surrender, saying that he was willing to take refuge in the Qin Dynasty, hoping that Daqin could protect Lin Hu......

Now it's good, Feng Jing's battle plan has gone a lot smoother, after all, he is still young, he is a little proud in his heart, and he thinks he has made a contribution.

It's just that Li Si frowned: "Why did Tou Manshan Yu expel the eldest son again, and ordered the four monarchs to enter the Shan Yu court, could it be that something happened to the Huns?" ”

"Tingwei guessed right!"

Qin Shi Huang had already read the notes sent by Heifu, and laughed loudly: "This matter is related to the detailed work sent by the Captain of Beidi County, in the name of Wu's merchants, Beidi County has explored the roads, terrain, and troops of the southern and northern regions of the Xiongnu River and drawn them on the map, so let's take a look!" ”

Li Si and the others were ordered to approach, but they saw a map made of hemp paper on the case, and its mountains, roads, rivers, and tribal pastures were all depicted in detail......

Feng Zai couldn't help but be shocked: "I only groped Lin Hu in the fine work of the county, and I never thought that the people of Beidi County had traveled to most of the Huns!" ”

But what surprised them even more was still to come, in the letter, Heifu explained what his subordinates had done in the Xiongnu, and the various strange behaviors of Touman Danyu may be related to the "discord plan" deliberately set up by Beidi County!

"Tou Man suspects that the eldest son and the four generals will join Qin to make trouble, so he wants to make the eldest son and the four monarchs enter the single court, and control them, who expected that his eldest son will be resolute and resolute, and he will go westward, or go to the Western Regions, or enter the Yue clan, and everyone in the four departments is in danger, Lou is annoying, Aries is close to the Huns, and his monarch has been tied up in the court, and Yan Yan Jun is afraid that he will not be able to return again, and under the persuasion of the governor of the northern county, he also decided to attach it!"

Feng Zheng and his lieutenants looked at each other, so what caused King Lin Hu to suddenly change his attitude was also the "discord plan" of Beidi County?

The same young generation, known as "able to write and martial arts", Feng Zai has always been dismissive of Heifu's low-born colleague in the past, and when he went to work, he heard that Heifu was in a neighboring county and was also a county lieutenant, so he had a desire to compete.

Although Heifu's strategy was initiated by Heifu, as a southerner, he came to the northern border counties as an official, and he was not familiar with the place, so Feng Zai didn't think Heifu could play any tricks.

Who would have thought that some time ago, Heifu first proposed to repair the Jingbian Temple, which won the favor of Qin Shi Huang, so that's it. Now that Shangjun has been tossing for half a year, he finally achieved results in the matter of Lin Hu, but in the end, the limelight was all robbed by Beidi County......

Feng Zheng felt very uncomfortable in his heart, but at this time, Qin Shi Huang stopped laughing and looked at everyone.

"Heifu said, Yan Yan is not as good as Lin Hu, near Helan Mountain, the Hun cavalry is coming in an instant, and the north should immediately send troops to settle in Yan Yan to help it counterattack the Huns. If you can take Yanyan and Huamachi as a stronghold, you can divide the southern part of the Xiongnu River into two, and when you send troops next year, you can wrap the Helan Xiongnu with Longxi County! ”

Heifu's strategy is clear, next year is a general attack, this year is a tentative small fight, taking advantage of the discord between the Xiongnu and the four departments, to take Huamachi as a bridgehead......

Qin Shi Huang especially appreciated Heifu's words to ask for war:

"Will hold the bow like a full moon, look northwest, and shoot the wolf! Heifu is willing to drive forward for His Majesty and be His Majesty's arrow! ”

"The son is obviously not good at archery, but he dares to make such a bold statement?"

Although it is a joke that Heifu is not good at archery, it is precisely his momentum that Qin Shi Huang appreciates!

However, it is really good to be in the border county and witness the beating of war drums.

In front of Li Si, Zhao Gao, and Feng Zheng, he said: "It was Heifu who proposed to me the first strategy to open up the northwest, and the first arrow against the Xiongnu should be shot from Beidi County!" ”

There is no need for the ministers to discuss, Qin Shi Huang struck a blow and said: "Captain Ting, immediately prepare an edict for me, order Heifu to send troops to Huamachi, Shangjun and Longxi also send 5,000 troops each, and respond to it on the left and right!" ”
