The Cao army attacked Hanzhong, the Yan army pressed into Qingzhou, the previous battle of Yanzhou Liu Yi sent troops just to respond to Xuzhou Liu Bei so that it was not only destroyed by Yuan Cao and the two to break their joint force, but also after the battle of Si Li, it was forced to send troops, so it was not a decisive battle between the two! And this time, Liu Yi has been recuperating for two years, during which he even sat back and watched Cao Cao take Jingzhou and Yizhou and hold back, waiting for the opportunity after Cao Jun's long battle! In such a situation, Cao Mengde also saw it clearly, but he had to do it, it was better to move dangerously than to sit and wait to be killed, and then he had to give up Qingzhou in order to use the victorious soldiers in the Han Dynasty and continue to fight continuously to implement his intention of winning by surprise, after all, there is still a gap between him and Liu Yi in terms of comprehensive strength at this time.

From the overall situation, the Yan army obviously occupies a certain advantage, whether it is the strength of the army or the people, Langsheng must be above Cao Cao, but there are always various unpredictable factors in the battle array, no one can calculate all the changes before the war, especially in the face of Cao Cao's art of war, it is not impossible for him to counterattack and turn the tables in one fell swoop if he is negligent, so Liu Yi has unprecedented caution in this war, and the more stable the battle situation is, the more favorable it is for him, Because there are the least changes in the stable situation, it is easiest to grasp the side with the advantage of strength without omission, on the contrary, in Cao Cao's case, he must seek change and strive to create an extremely complex situation, it can be said that the psychology of both sides has set the tone of the war!

In the first battle of Hanzhong, Cao Jun under the leadership of Xiahoudun and Cao Hong finally took the Dazhai of Zhang Xiu'an camp after two days and one night of uninterrupted fierce attack, of course, the price paid should not be underestimated, Dian Wei was seriously injured in a battle with Ma Chao, Cao Hong was also injured in the attack under the knife of Pang De, plus nearly 20,000 casualties, Cao Cao has countless battles in his life but has never suffered such a huge blow in a war! The strength of the Yan army did not surprise him, but in the past two years, the development of the opponent's army and the innovation of tactics still shocked him, whether it was the Mo Fang crossbow of the equipment battalion or the infantry artillery coordinated short assault by Zhang Xiu, which had never appeared in the history of warfare in the past, but it was a blockbuster without a shot for two years!

Of course, these will only be deeply hidden in Cao Mengde's heart, at least on the surface, Cao Jun still captured the Yan Army Dazhai, and did not fail in the first battle in Hanzhong, a group of strategists and generals can see that Zhang Xiu is not retreating with all his strength, it must be Zhang Hu's plan, from the orderly and appropriate cooperation of the Sizhou battalion cavalry in his retreat, it can be seen that Zhang Zicai is using this method to consume the sharp spirit of Cao Jun's victory in Yizhou. And with the help of Zhang Luhan's Chinese army, the terrain of this battle is also controlled in the hands of the other party, after taking Chang'an Camp Dazhai, Cao Jun is facing two dangers, Micang Mountain and Dingjun Mountain, this is another huge test!

Liu Yi's Tian'er has spared no effort to explore the details of Cao Cao's subordinate territory many years ago, and the dark arrow in Meng De's hand is no exception, and the distribution of the Yan army's military strength in Chang'an and Sizhou Cao Jun knows a lot about it, the Yellow Shirt Army, Yan Yun Army, Chang'an Battalion, and Sizhou Battalion are all the troops of Liu Yi here, according to the analysis of this person's recent military style, there will be at most three armies used in the battle of Hanzhong, if you make a choice between the Yellow Shirt Yanyun and the two armies, Cao Cao can be sure that it must be the Yan Yun Army led by Zhang Wenyuan, the general of the Yan Army!

Xu Huang's Longxiang Army and Zhang He's Tiger Guard Army have always been known as the two trump cards of the Yan Army, but in recent years, under Zhang Liao's command and careful building, the Yanyun Army has gradually come to the top, speaking of tradition and military exploits This army is by no means under the first two, when it was in Xingba to sweep Liaodong and Goguryeo relied on this elite of a hundred battles, but later the Youzhou Army was expanded, and many soldiers in the Yanyun Battalion were scattered and supplemented into the various armies, Gan Ning was sent by Liu Yi to form the Water Battle Lion Flying Tiger Army, and it was Zhang Wenyuan who was responsible for leading the army. The talents of his generals in the first battle of Sizhou are undoubtedly revealed, but it can be said that without Zhang Liao, there would not be Liu Yi's feat of annihilating the Han and Zhang coalition forces, and Cao Cao is also very fond of it! Of course, he would definitely not know that if Liu Yi hadn't come, these three generals would have been among the five sons under his account, but now they are still fierce rivals!

Originally, in Cao Cao's heart, although the Yan army was elite, the Chang'an battalion and the Sizhou battalion were recently newly formed divisions, and there would still be an experience gap between them and the old powerhouses such as Long Xiang and Huwei, but in this offensive and defensive battle, the kind of combat power shown by Zhang Xiu's department was like a new army? He also had to make a pre-war estimate of the Yan army's combat strength too high again, so that once Zhang Liao's Yan Yun army entered the Hanzhong battlefield again, the difficulty of his victory would increase, and after receiving the news of his attack here, Liu Yi would never sit idly by, and it would take time for a long time for reinforcements to continue to come from all over Youzhou, so he could only fight quickly in the battle in front of him, and the current situation was that Liu Yi could afford to drag him but couldn't afford it, and he must make a breakthrough in the battle of Hanzhong as soon as possible in order to contain the energy of the Yan army in Qingyan, In order to achieve its goal of encircling Wei and saving Zhao!

On the night of taking Chang'an Yingdazhai, Cao Cao immediately made a decision after consulting with a group of subordinates, Xiahoudun led an army of 50,000 to attack Micang Mountain, and Cao Hong led the army to attack Dingjun Mountain, his injuries were not enough to affect his command of the army, and such an offensive and defensive battle did not need to be taken by himself! And Cao Cao himself dispatched non-stop ahead of the second general, he had to firmly stick to the main force of the Yan army led by Zhang Hu to fight with it, at least to contain it so that he could not be distracted by other things, so that the second general could successfully take two dangerous places. At this time, what can make Meng De and everyone feel fortunate is that it is the Han sergeant and not the Yan army who are guarding these two places, otherwise it depends on Zhang Xiu's performance when he defended the village and the more dangerous terrain, and I don't know how much it will cost to achieve the goal!

As a master of the art of war, he has a lot of experience in a hundred battles, Cao Cao will not be wrong about such a battlefield situation, after getting the military order of the military division, Zhang Liao left Mu Shun to lead 10,000 soldiers to sit in the tiger prison and led the remaining main force to Hanzhong day and night, he didn't even wait for Zhang Yan to come to change the guard! In this war, the elite of the Cao army dispatched more than 300,000, and at this time, all the troops in the hands of the military division were only 1440,000 in one place, and the gap in strength was so great that there was a problem between the cooperation between the two armies.

Zhang Liao led the Yan Yun army to Hanzhong non-stop, and another Yan army elite Tiger Guard army is also doing its best to rush to Luoyang, the so-called victory and defeat, even if Zhang Hu and the generals have full confidence, but in the planning of Liu Yi and others, it is taking into account the extreme situation that Hanzhong was captured by Cao Cao's army! In any case, Zhang He must rush to Sizhou at the shortest speed and then join the battle against Cao's army, with the reinforcement of this strong army, the strength in Zhang Hu's hands is really enough to compete with Cao Cao, at least the Yongliang area must be protected!

Yan army is good at long-distance running, fast marching is its specialty, the Tiger Guard is one of the leaders, since the first battle of Jizhou Zhang Junyi in Youzhou for three years, has long been eager to fight, coupled with Tian Yu's strong support in logistics, the speed of the Tiger Guard in Youzhou can only be described as a miracle, three days to run out of nearly 600 miles! But at this rate, it will take at least more than a month for the Tiger Guards to reach the land of Hanzhong, and in the rapidly changing battlefield, this time is enough to make a huge change in the battle situation.

Zhang Hu is already well aware of this situation, although Liu Yi and others have been prepared for the loss of Hanzhong out of strategic needs, but Zicai must not allow this situation to appear, in the face of the continuous offensive of the Cao army, Zhang Hu resolutely led the second battalion of Sizhou in Chang'an to meet it, but the Cao army is in the advantage, but Zhang Hu still has more than 30,000 Sizhou battalion iron cavalry in his hands, and this combat power will definitely play a pivotal role in this war!
