During the four hundred years of the Han Dynasty, due to various reasons, a large number of Xiongnu often surrendered to the Han Dynasty. The Han governments adopted relatively proper resettlement policies for them. The most important measure was to set up a special residential area for them: vassal states. "Records of the Grand Historian: Biography of General Wei's Cavalry" records that after the second battle in the second year of Yuanshou, the Xiongnu Kunxie King led more than 40,000 people to surrender. Emperor Wu "was divided the five border counties and were outside the border, and they were all in Henan. Because of their customs, they became vassal states." That is, five vassal states were set to treat them, which was the beginning of the vassal state.

In the Hetao region of the Han Dynasty, the Yellow River flowed smoothly. There were many tributaries and lake ports in the riverside plains around Ningxia and Inner Mongolia, so there were abundant water sources and convenient utilization. Hetao has an inland climate, and natural precipitation could not meet the needs of crop growth. Agriculture relied almost entirely on irrigation. Therefore, the development of water conservancy was an important measure for the development of Hetao in the Han Dynasty.

During the reign of Emperor Wu of Han, the country had a climax of water conservancy construction. Although Hetao was in the border, the water conservancy construction was not reduced to the mainland. "Records of the Grand Historian: Book of Hequ" says: "Those who work in charge compete for water conservancy. Shuofang, Xihe, Hexi, Jiuquan all diverted river water and river valley water to irrigate fields." "Pingzhuan Shu" also says: "The latter period wanted to save the grain of water of the main pillar, and penetrated Fen, and river canals to irrigate fields, and the authors were tens of thousands; Zheng was back to Weihu canals at that time, and the direct canals were dug from Chang'an to Huayin, and the authors were tens of thousands of people; Shuofang also passed through canals, and the authors were tens of thousands of people, each with two or three periods, and the work was finally completed, and the expenses were also huge. "From the above records, since the reign of Emperor Wu of Han, Hetao has become a key area for the construction of water conservancy in the country, and its scale is comparable to that of large-scale projects in the mainland.

Later, during the Wei, Jin, Southern and Northern Dynasties, the Hetao region was a major area for competition among many northern regimes. Because the water and grass are abundant here, it is suitable for grazing and farming. Moreover, the population is very large. Compared with the Hexi region, which has a total population of less than one million, the Hetao population at this moment exceeds one million.

Among them, even though the Han population has gone through many twists and turns, there are still nearly 1.35 million people still in the Hetao area, and the others are mostly Turks or various nomadic peoples.

"...Since the Qin Dynasty, this place has been the land of China. Now, it is owned by the Turks. The water and grass are abundant here, suitable for farming and grazing. Moreover, it is located in a key junction. It can directly point to the royal court of the Eastern Turks in the east, and can be connected with Lingwu County in the west..."

Wei Yunqi's ideas and ideas made me and all the ministers very moved. After taking this place, the Chinese Empire gained a large area of ​​important strongholds for future control and attacking grassland areas, and increased the thickness and strength of defending Guanzhong.

"However, it's not easy to get this place." Wei Zheng, the chief dean who had no military talent, pretended to look at the map and shook his head. "This is a thousand miles away from the Yan'an County where we are."

"Not only is the Liang Shidu, but there are also a large number of Turks and other nomadic tribes in this area. In my opinion, if we attack this area, then the Turks and Liang Shidu will inevitably try their best to stop them. I am afraid that there will be a lot of troops..."

Hearing this, Yang Gongren next to him couldn't help but smile. "Director Wei, you forgot one thing, we have a boat."

When Yang Gongren saw everyone's eyes lit up, he couldn't help but show off with pride: "My China Yellow River Navy now has more than 100 warships, and there are more than 40 warships located in the upper Hexi area. In addition, there are more than 120 transport merchant ships in the upper reaches."

"...Our warships and merchant ships can all go straight to the upper reaches of Longmen from the Hexi area. In recent years, because of our trade with the Eastern Turks, our ships have often traveled in this area. They are not alert, and in many towns in the northern part of Chilechuan, we Han people can still account for the majority. Therefore, I think that if we want to seize the entire Chilechuan, we must first seize this place. Our warships have the ability to cut off the connection between the two banks of the Yellow River. Therefore, after we take the north, we can rely on warships to block the connection between the Turks in the Chilechuan and the Yellow River outside the Yellow River."

"Brother Gongren said this is a great kindness. Your Majesty, I think this strategy is very possible." Wei Yunqi's eyes lit up immediately. After standing in front of the map for a long time, he bowed to Yang Gongren in admiration and said to me happily.

"More than 120 ships are probably not enough?" Yang Shidao next to him said with confusion, caressing the three new long beards. After several years of hard work, this guy finally returned to Chang'an. He is now the Minister of Propaganda Department, the Ministry of Civil Affairs and Jingzhao County. Anyway, the three are the least ones. If you want to work only one job, you have to spend at least three years.

Let’s wait until the middle and grassroots officials below are trained and outstanding, otherwise, it will be no good for the country to suddenly reach a high position.

I shook my head and jumped out to offer suggestions. "It's okay, our warships have no rivals in the inland rivers or oceans. At worst, let the soldiers cut wood into boats and have warships to support them, so there should be no problem."

"This is really okay. The important thing is that we can mobilize our troops to the Hexi land, and from the Hexi land, we can go down the river, so that we can avoid our ears and ears." Wei Yunqi clewed his hands with his high hands, and his eyes became brighter.

However, when to launch an attack is a question, and there is also where to send troops to come? It also needs to be considered.

Finally, it was decided to recruit a field army and two field divisions from the Bashu area, a field army from Hexi and Xiqin areas, and a security army from Guanzhong. Wei Yunqi was the head coach, Shi Danai was the deputy commander, and Han Xiong was the chief of staff.

Of course, we have to wait for the army and two divisions recruited from the Bashu area to arrive in the Hexi area first, which will take at least one month. During this period, the Chinese Empire envoy headed by Tang Jian, the Minister of Foreign Affairs of the Chinese Empire, was sent to the Western Turks to envoy.

Of course, it is to discuss the expansion of bilateral trade between the two sides, borrow interests, and try to hold the Western Turks back first.

At this time, twenty days have passed since the Chinese Revival Army left Tongguan. Compared to Li Mi, Liu Wuzhou and Wang Shichong, who were beaten to death, their noses and mouths were covered in blood. Liang Shidu's life was much better. He retracted his lair and considered his next move.

After Dou Jiande was forced to return to Huaibei, Qin Qiong voluntarily withdrew from Huaibei area and returned to the south bank of the Huai River. This made Dou Jiande's 200,000 reinforcements run away.

At this time, Dou Jiande received the news that the defenders who were left behind the Yongji Canal Floating Bridge were attacked and requested rescue. Dou Jiande could only curse and slapped his butt and rushed back to Liyang, and then prepared to cross the Yongji Canal to head towards Weijun. However, when he arrived at Yongji Canal, he was shocked. The 20,000 defenders who had already built the pontoon bridge and guarded the pontoon bridge were gone, leaving behind a broken wood residue after being burned by the fire. As for the 20,000 defenders, judging from the blood on the ground, it was probably a little bit of good fortune.

Instead, the tall and majestic Chinese Empire's domestic river naval warship was showing off its might in the Yongji Canal. The Xia army could only stare at such a giant ship, because such a tall and majestic solid giant ship was definitely not something that ordinary infantry and cavalry could take down.

Dou Jiande decided to give it a try, and the result was that the crossbowman on his side had just approached the bank of the canal, and rows of small portholes opened on the side of the battleship, revealing countless crescent arrows. Immediately afterwards, there was a trembling buzzing sound of crossbow strings, and the sharp whistling sound of the crossbow arrows.

Rows of short arrows rushed out like headless flies, and then thrust into the river bank in a dense manner and plunged into the human body. All the crossbowmen who had not yet arranged the formation on the river bank and ignited the rockets were all in great danger. They turned their heads and ran back in an attempt to avoid the sudden attack of the desperate rain of arrows.

Dou Jiande could only stare blankly, and then suddenly shot an iron ball that looked black from the warship, landing more than 200 meters on the river bank. Then, an orange-red fire light burst out in full view of everyone, and the roar like thunder.

Dou Jiande, who was not far away, almost fell down the horse by a dog chewing shit. Then, several more groups of things were fired on the boat, which scared the Xia army back nearly a hundred meters. After that, the people on the boat shouted with a loudspeaker. Dou Jiande and Xia army realized that the ones shot from behind were leaflets.

The meaning is very simple. I despise Dou Jiande for breaking the contract after forming an alliance, and then he dared to seduce Fu Gonghu, the general of our Chinese Revival Army, with his daughter. All of the above made my Chinese Empire furious. Today, I would like to give you Lao Dou a warning, don’t think about the idea of ​​fighting in Shanxi, and immediately withdraw your troops and return to Hebei, otherwise, our Chinese Empire will retain the right to use force.

Dou Jiande was so angry that he vomited blood on the spot, but the problem was that the Xia army, who did not have super-range weapons, could only watch these tall and majestic warships showing off their power without any help. In the end, Dou Jiande could only retreat back to the newly occupied city of Liyang in disappointment, and then consider how to pass through Yongji Canal. After all, the navy of the Chinese Empire was really not a joke.

His powerful combat effectiveness and dominance towards the inland and offshore waters of China also made Dou Jiande deeply afraid. In the end, Dou Jiande ordered the division of troops, intending to create an illusion of striking the river from multiple places, and ordered large boats to build ships. Even if he could not compete with the warships of the Chinese Empire, he would have to use some warships to protect his army from crossing the river.

In this way, this place has completely become a stalemate. As for Wang Shichong, he was frightened in Luoyang, while adding troops to his brother Wang Shiyun, and sending envoys to him, putting on an extremely low attitude, hoping that this young master would not be provoked by others and attack him, the harmless Emperor of Zheng, who is harmless.
