In the seventh year of the Han Dynasty, in May 208, Xiangyang County, Jingzhou, five years ago, a generation of heroes Cao Mengde was not far from here to accumulate firewood and self-immolation, the Han army decided to settle the two places of Jingbei in Shuzhong in a war, and Liu Yi's biggest opponent in this life finally collapsed! In the Han world, only Sun Ce and Liu Bei are partial to the south of the Yangtze River, which can be swept into the dust of history in three years in Liu Yi's planning, because both the military and the economic north are in an overwhelming advantage, and this advantage will become bigger and bigger as time goes by, and it can be seen from the prosperity of Xiangyang's hundred industries that this assertion is correct, and the population has grown by 36,000 households in five years!

The growth of population is only one part, the scale of the city, the increase of industry, the planning of the streets and the exquisiteness of the architecture can be circumstantial evidence, especially the latter, the new thing brought by Liu Yi, its role is not only in the military and agriculture, with the rapid development of casting capacity and the labor of the Japanese slaves full of sadness and blood and tears, now the craftsmanship in all fields of the Han Dynasty has developed rapidly, look at the current Xiangyang, four or five storey buildings abound, extremely luxurious and rich, which was almost unimaginable five years ago! Of course, the biggest gainers among them are Gan Ning's Flying Tiger Army and Li Tieniu's Vermilion Bird Battalion, and the benefits of equipment are unparalleled in the world!

The reason why he didn't do anything to Sun Ce and Liu Bei within five years was because there was another force that had caused a lot of trouble to Emperor Kaiyuan, and that was Xianbei Tuoba! To deal with the biggest old enemy Cao Cao, Liu Yi mobilized almost all the troops in his hands, manpower and material resources, amounting to millions of people, and in Xianbei's view, after such a huge loss of manpower and material resources, the Han's deterrence against them will definitely be reduced for a period of time, and the actions they take are aimed at the Xiongnu Wuhuan, once they succeed, they will be able to compete with the Han in time. It is not wrong to analyze Xianbei's strategy from the past, but in the final analysis, they still underestimated Liu Yi's determination to the territory!

On the battlefield, Liu Yi has the prestige of winning a hundred battles, and a number of famous generals under his command have established the prestige of the Han army with their own military exploits, but behind these there is one of the biggest heroes, this person is none other than Tian Yu, the invincible Han army is supported by an extremely perfect logistics support system, which all the generals have a deep understanding of, under the command of the Kaiyuan Emperor, you only need to be a pure soldier to consider the problem from a military point of view, as for the weapons, soldiers, grain, grass and horses will be arranged in all aspects, These are the strength of the logistics department!

Liu Yi said to Tian Yu a term for sustainable combat rate, but now it is often talked about by Ji Ming, and the support of logistics support for the campaign is divided into one to five levels from the perspective of sufficient materials, but for Cao Cao, the largest battle, the index is four for Tian Yu! In such a big war, the Han army can fight for a year and a half without worrying about the lack of strategic materials, and it will not have any impact on the production of the north, and it can even stimulate the prosperity of the market, all of which can be said to be the accumulation of Lang Sheng for more than ten years, but the Xianbei people obviously do not understand the reason inside!

On March 18 of the third year of the Han Dynasty, Xianbei gathered 170,000 cavalry to attack the Xiongnu Wuhuan on all fronts, and for a time the two clans were suppressed by the elite forces of the other party was very embarrassed, except for the cavalry who participated in the Sili battle, the rest of the soldiers were obviously not as elite as the other party, and Hu Yanshuo and Yu Fuluo had to ask for help from the Kaiyuan Emperor as a last resort! Originally, Liu Yi was preparing for the battle against Sun and Liu in Jiangnan, but after comprehensive consideration, he decided to solve this northern threat first!

The autumn wind sweeps the leaves, chops the grass and removes the roots, and if it doesn't come out, it will be killed! Dealing with Xianbei is not to fight with Cao Cao, Liu Yi has no scruples in his heart, now the Xiongnu Wuhuan is already a subject country of the Han Dynasty, and the other party dares to come to make a mistake because he needs to recuperate after a big war, they think wrong, this is just a matter of order, since someone is looking for death, Liu Yi will not give them a ride, and if they want to fight, they will give the other party a ruthless one like a wolf, and kill it completely!

On the ninth day of the fifth month of the third year of the Han Dynasty, the Kaiyuan Emperor took the crown prince Liu Huan as the left marshal of Pingbei, and Zhao Yun, the king of Changshan, as the right marshal of Pingbei, commanded the 230,000 troops of the elite iron cavalry battalion of the Han Dynasty plus the second battalion of the infantry Yanyun Feiyan, (Feiyan was newly established after the battle of Jingxiang, the orthodox leader was forbidden, and the deputy commander Lejin, but the five good generals of Cao Ying were in the Han army!) As well as the guards under the command of Liu Xin, the king of Lu, a total of 370,000 horse infantry troops out of Beiping and the Northern Expedition to Xianbei, the original Kaiyuan Emperor intended to drive the imperial conquest of the left and right Prime Minister Zhang Hu Jia Xu all said that the south is uncertain for a day, His Majesty can not leave the Beijing division lightly, Liu Yi just gave up, and the unprecedented use of double marshal is to increase the authority of the crown prince Liu Huan Rizhong!

Speaking of the setting of this double marshal or out of Zhang Hu, in Liu Yi's opinion, there is no second order, the supreme commander can only have one person, Liu Huan is enough to be a staff officer with the army, but in the eyes of Zhang Hu, Jia Xu, Xi Zhicai and others, the identity of King Yan and the prince is not trivial, otherwise there is a difference between up and down, and in the end Liu Yi also had to compromise, but before going on the expedition, he still told the eldest son the so-called "one general is incompetent, exhausting the three armies." "His responsibility for this expedition is to watch and learn, and it is okay to give advice, and the specific tactics cannot be ignored! And with Liu Huan accompanying him to the expedition, the other coach is none other than Zhao Yun and Ganning, and if he is the general Xu Huang and Zhang He, the generals in the army, will also be constrained because of their concerns about Liu Huan's identity, and the Ganning Flying Tiger army locks the Yangtze River, and the position of Pingbei coach naturally falls on Zilong.

As for the Yanyun Feiyan Second Army, it is completely a geographical factor, the two aces of the Han Army, Xu Huang and Longxiang's army, Zhenjingbei, and Zhang Hehu's guard army stationed in Shu are too late, and Zhang Liao's Yanyun Army's combat power is by no means below the first two, and although Yu Ban's Feiyan Army is newly formed, the old foundation is the Qingzhou battalion of Cao Jun, and now that Cao Cao has gone, it is a war with foreign races, Liu Yi does not have too many concerns! As for Yu Wenze's ability to general, there is no need to question it, speaking of Xianbei's attack, it also contributed to the surrender of another general, Lejin, like this, who doesn't want to show his skills in this battlefield?

The battle of the north from the beginning of the third year of Kaiyuan to the end of the spring of the fourth year, Zhao Yun commanded the Han army to fight more than 100 times, annihilating 160,000 enemies, Tuoba Yu was killed and among the ten thousand troops, the first brave man of Xianbei did not support forty rounds in the hands of the first rising star of the Han Dynasty! This battle is also a battle of Liu Xin's martial arts, King Changshan has a saying that King Lu at this time is not half a point sure that he is going all out, Zhang Liao Yu Ban and others are all recognized, and Liu Xin, the king of Lu who is talented, is indeed incomparable!

More than 100 battles of each army performance is extremely outstanding, but the most dazzling is the king of Lu Liu Xin, not only has the world's martial bravery, his command ability has also improved by leaps and bounds in this year, especially in dealing with the Xianbei guerrilla more effective, in the later period Zhao Yun simply let go of Liu Xin, and the iron cavalry battalion generals Yan Ganghua Xiong Fan Chou Yan Wen and others are also obedient to the king of Lu, this is not based on Liu Xin's identity, it is the trust accumulated in actual combat again and again!

After this battle, Xianbei was completely devastated, the remnants fled westward, and Zhao Yun easily destroyed the Buyeo in collusion, and the northern frontier of the Han Dynasty expanded thousands of miles again, and the battle of the northern conquest was also in the special books and annals. After two years of cultivation, Liu Yi finally began the process of unifying the final battle, Chibi, here will finally witness the glory of the unification of the Han Dynasty!

(There are many book friends who have said that Wolf Three is a bit unfinished, yes, and now Xiao Zhuge is also working hard to make up for the ending, as for the new book Yu Ding Tianxia will definitely be uploaded on February 1, I hope that book friends will strongly support, and some new chapters will also be released in the group!) ）
