North of Yunnei County, at the foot of the Great Wall.

The vanguard of Dulan and Nili suddenly arrived, and there were only three hundred guards on this important Great Wall Pass at the northern end of the Yunnei. The Turkic cavalry rushed over like a tide, and black clouds covered the city. The defenders on the city rushed to fight, but in the end they only struggled for a while. In less than an hour, the Great Wall Pass had been lost.

After taking this important barrier, Du Lan and Ni Li had already tore open the already broken outer Great Wall defense line in the northernmost part of the Great Sui Dynasty, and tore a hole.

Standing on the broken Great Wall, Du Lan was in a good mood and said to Nili Khan with a smile: "I remember that this was the capital of the Northern Wei Dynasty, and this was the capital of the Northern Wei Dynasty. There were six towns to guard the northern line north. How prosperous this place was at that time. It is said that the capital of the Pingcheng capital once had a population of one million."

"The Tuoba family is indeed amazing. Unfortunately, they were bewitched by the Han people. They eventually moved the capital to Luoyang, and they still had to promote the sinicization. The good grassland overlord was not good, but they were not good at wolves, but they had to go to the Central Plains to be sheep. As a result, in just 30 years, there was a great rebellion in Six Towns. In just 35 years, there was a change in Heyin. Erzhu Rong threw Empress Dowager Ling, the Young Emperor, and more than 2,000 civil and military officials into the rolling Yellow River by the edge of Heyin. After moving the capital to Luoyang for 40 years, the Northern Wei was finally controlled by Gao Huan, Yuwen Tai, and divided into the East and West Wei, which was actually destroyed."

"It seems that Du Lan Khan is quite familiar with the Northern Wei Dynasty." Ni Li smiled.

Du Lan put away the feeling in his heart. His familiarity with the history of the Northern Wei was because his father Sha Boluo's special request for their brothers, allowing them to learn literati culture and read the history of the Han people. But at the same time, his father used the history of the Northern Wei to warn their brothers. He let them understand that although they were asked to learn Han culture, it was just to understand Han people, not to be Han people. Only when the wolf is wild can it be fierce. If the wolf does not eat meat and eat grass, then the wolf will be no different from the sheep. How powerful the Tuoba family of the Northern Wei Dynasty was, it is also the only Hu clan who once entered the Central Plains from ancient times to the present. Even if they ended the period of the Five Barbarians and Sixteen Kingdoms, unified the north and did not destroy the Southern Song Dynasty, but this was enough to be praised by future generations. But Tuoba

After entering the Central Plains, the clan lost himself. He forgot their origins, but their identity became Han people who were not Han people, and eventually died. Every time his father Sha Boluo talked about the Northern Wei movement of the capital Luoyang and reformed and the sinicization and destruction, he was always full of sighs. His father once told him that if the Turks could enter the Central Plains like Turkish, they would never go the path of sinicization. They had to adhere to the tradition of the Turks and encircle the northern part of the Central Plains as a pasture for the Turks. And if the Han people were not suitable for grazing, they could not use Han people as officials. They had to confine Confucian Chinese culture and demote the Han people to slaves. They were firmly pressed under their bodies so that they could never turn over. If necessary, they could massacre and clean up several times. After all, there were too many Han people, and they were always threatening the Turks.

Unfortunately, my father never had the chance to enter the Central Plains in his life, and he attacked the Sui Dynasty twice in large numbers. Both were defeated. The subsequent dispute over the Khan throne caused the Turks to completely fall into civil strife, and then became a loser and was forced to surrender to the Sui Kingdom. If he hadn't felt too depressed, his father wouldn't have died so early.

Now, what my father was unable to do back then, he would do it for him.

"I think we should divide the troops into two groups, from then onwards south across the Great Wall, and directly attack Yunnei County and Heng'an Town. The route goes east along the border road of the six towns of the Northern Wei Dynasty and attack Huaihuang." Nili spread out a sheepskin map, which depicts the area where Yinshan, Yanshan and Taihang Mountains meet in detail. He pointed to his current location, "The army in the south surrounds Yunnei City and Heng'an Town before the arrival of Turkic reinforcements, and surrounds Yunnei City and Heng'an Town before the arrival of Turkic reinforcements.

If you have the chance, you will directly capture these two cities. If you don’t have the chance, then send some troops to surround them without attacking them, and divide them into two groups, attacking the east along the Great Wall, and sweep the Changqing, Tiancheng and Huaian Zhucheng along the Nanyang River, and it is best to surround Daning Pass. Block Huaihuang’s southern retreat route, completely encircle Huaihuang and isolate Huaihuang. Another group of troops will advance east along the Sanggan River Valley, sweep the Zhuolu and Huailai in Guizhou, and finally attack Junduguan directly."

"Will the troops be too dispersed?" Du Lan had to praise his boldness after seeing Ni Li's plan, but he was a little worried. After all, all the Sui Dynasty troops are heading north, with 250,000 in Yanmen, Taiyuan, and 100,000 in Youzhou.

Ni Li said confidently, "Soldiers are more important than speed. We must take advantage of the fact that Gao Bing in Taiyuan and we must act quickly before we understand our latest plan. As long as we can take down Yunnei and Heng'an cities, the Shuozhou of the Sui army will be no longer safe to defend. Unless they want to fight with us in the wild cavalry, they will have to retreat to Yanmen and Loufan Pass. If we can attack more rapidly and sharply, we will have a great chance to capture Daning Pass before the Sui army in Youzhou reacts and isolate Huaihuang. If the blessing of the heaven of immortality, we might be able to directly attack Jundu Pass and enter Youzhou."

"The military gate is dangerous, not inferior to Yanmen, I'm afraid it will be difficult to take it in a short time." Du Lan had attacked the border of the Sui Dynasty before. He knew that although the Sui army's outer Great Wall was weak, the guards of the second Great Wall were very strong. Jundu Pass, as the northwest gateway of Youzhou, was even more important. He stationed heavily in heavy troops all year round and was very close to Youzhou. Reinforcements could reinforce at any time. If he wanted to raid and seize Jundu Pass, he didn't have much confidence at all, and even felt that it was impossible to complete it from the bottom of his heart.

Nili smiled indifferently, "It doesn't matter if you can't take the army's guard. As long as you can quickly reach the army's guard, we can block the Sui army within the army's guard and prevent them from leaving the gate." Nili's hand drew a circle on the map, "Shuo, Gui and Wu, such a large piece of land, if it goes well, it's enough to swallow these. If it goes well, we can take down Weizhou, or even rob Xinzhou. Brother, aren't you satisfied that you can plunder such lands in several states at once?"

"Satisfied!" Du Lan looked at the circle that Ni Li was drawn, his eyes were shining. This was a place of several states. Huai Huang alone was enough to eat. He had heard many legends about Huai Huang, which was simply a mountain of gold and countless wealth. It is said that the population alone had no less than 500,000 people. Even if it was divided equally with Ni Li, he could still share 250,000. With so many people, his power would immediately increase.

When Nili made this plan, his core plan was actually Huaihuang.

The attack on Yunnei and Heng'an was because as long as these two towns were occupied, they would control the strategic points of the northern part of Shuozhou, and the Sui army would be in a very embarrassing situation. If they left Shuozhou City, then they would have no strong city to rely on in the north. At that time, they would have to face either fighting the Turkic army in field or attacking the Turkic army that occupied the favorable status of Heng'an and Yun'an. Occupying these two places, the Turkic army would be equivalent to defending the passage in and out of Hedong, and they could attack and retreat. At the same time, they also protected the Turkic troops who went to sweep away the two prefectures of Guiwu, blocking the rescue of the Sui army in Hedong to Huaihuang, and ensuring the Turkic army's siege of Huaihuang.

Nili never really thought about occupying the four prefectures of Shuo, Wei, Gui and Wu outside Yanmen Pass. He never thought about it at all. What he thought was to sweep the four prefectures and snatch all the money, silk, women, people, cattle and sheep, and all the cattle and sheep.

Du Lan agreed roughly with this plan. He never thought of attacking Taiyuan, breaking into Youzhou, or even Luoyang. I believe that even Datou Khan would not have thought of attacking Chang'an. What they thought was to rob the border areas of the Sui Dynasty and burn and kill and plunder them. They not only robbed the Turks of the shortage of copper, iron, salt, cloth, and other important things, but also declared their strength to the Sui Dynasty. The most anticipated ending was that the Sui Dynasty was so important like Zhou Qi back then, paying tribute to the Turks, and sending gold, silver, and silk to the princess. Of course, when the Turks were stronger, they would not mind robbing the Sui Dynasty's father-in-law, or simply like the Tuoba clan, heading south into the Central Plains, commanding the tens of miles of the Central Plains, and enslaving millions of Han people.

Now, it is not yet that time. It is enough to show the Sui people their courage and strength while snatching one first and gaining benefits.

Huaihuang's wealth has long been heard of, and Huaihuang is even prominent on the frontier. Outside the Great Wall, although he heard that Huaihuang had built many towns and forts and had many soldiers, Nili never thought that Huaihuang's lively border city had a strong military power. In his opinion, the most important thing is to make preparations first, cut off Huaihuang's retreat, cover two sides, and prevent Huaihuang's money and grain population from being withdrawn into Youzhou. As for whether to fight or not, this was something he had never thought about, because they had 200,000 troops and 100,000 Tieler troops heading south. Could it be that their 300,000 troops could not defeat a small Huaihuang? A joke.

The important thing is to ensure that the big fish Huaihuang is not discovered in advance and will escape.

"There are a few hard bones that must be gnawed first." Ni Li said to Du Lan, "Yunnei and Heng'an must find a way to take it, and at least the Sui army cannot reinforce the two cities. This is the top priority. If we cannot take these two cities, then the troops we sent to the second gate of Daning and Jundu Pass will have worries. In addition, Jundu Pass can surround but not attack, but Daning Pass must be taken."

After hearing Ni Li's words, Du Lan was also thinking about the small plan and divided the troops into two groups. The south route was obviously more tasked and more pressure. He had to besiege Yunnei and Heng'an towns, and swept the Yanghe and Sanggan Rivers. In the end, he had to seize the important Great Wall Pass, the Daning Pass, and the gateway of Youzhou, and the army that surrounded the northwest gateway of Youzhou. The south route also had to divide the troops into three groups. Not to mention the other towns, the most important ones that had to be captured were Yunnei, Heng'an and Daning. Not to mention this, the army that entered the Great Wall to fight must also face the Hedong Army that could rush to Yunnei for reinforcements at any time from Yanmen and Shuozhou, and the Hebei Army that could come out of Youzhou Army.

Too much pressure! (To be continued...)
