By the time of the Song Dynasty, the coordination of formation and tactics had become a necessary subject for almost all officers. That is to say, any qualified officer in the Song Dynasty can become a commander in the Tang Dynasty, and when he arrives in the Han Dynasty, he can definitely compete with the "Champion Hou" Huo Quai, and in the Spring and Autumn Period and the Warring States Period, these people can dominate the six countries and shock the world. In the early Northern Song Dynasty, the quality and equipment of the soldiers, as well as the command ability of the officers, were almost at the peak. The reason why it is said to have reached the peak is because these advantages are not obvious after that. In the ancient Song Dynasty, industrial technology and technology reached its heyday, which meant that large heavy weapons began to be invented and used. Ancient cannons, shooting crossbows, battering rams, trebuchets, etc., these things are comparable to manpower. For example, although the ancient cannon was fixed and could not be moved casually, the power was huge at that time. Even if the archer is the most sophisticated, the bow and arrow are the strongest, and he can only shoot one hundred and fifty or sixty paces, and if he exceeds one hundred and twenty steps, he will not be able to keep his head accurate. Moreover, a bow and arrow can only shoot at most one enemy, and it may not be able to directly kill the opponent. At that time, one step was equivalent to half a meter, that is, an arrow was fired, and the effective distance was seventy or eighty meters, and it was best to be within sixty meters to ensure accuracy. But the cannon is different, not only can it be completely covered within two or three hundred meters when it hits, but if it hits, it can definitely kill the opponent directly, and it can kill a large area. With these powerful weapons, coupled with the amount of armor to protect the soldiers, the army of the Song Dynasty gradually did not pay attention to the training of soldiers, and only knew how to strengthen the maintenance and training of large weapons. As a result, the Song army relied too much on these big guys, and the personal quality of the officers and soldiers became worse and worse.

On the one hand, the Song army was negligent in training soldiers in individual skills, and on the other hand, the Jin state was established by the Jurchen ethnic minority on horseback. As a result, although the Jin State lacked the cover of large weapons, it captured most of the Northern Song Dynasty with its bravery and superb horsemanship. After the Song Dynasty moved south, the Southern Song Dynasty was established in Lin'an and continued to run his ******. However, due to the lack of large weapons, they had to be distributed at important passes, so the Song army had to train soldiers again in individual quality. Although the national strength of the Southern Song Dynasty was not strong at that time, and the soldiers almost did not even have the same decent weapons and armor, they still trained a group of elite soldiers and strong generals in Nas. This is all due to various reasons, first, Jin Bing is a soldier of an ethnic minority, good at riding, but does not know how to fight. Therefore, the pace of Jin Bing's southward movement was hindered by the Yangtze River. Second, many soldiers died because of Jin Bing's family, and almost every soldier occasionally read and Jin Bing had a hatred for killing their parents, brothers, wives and children. Driven by great hatred, the hatred of the soldiers offset the lack of their own weapons and training, and thirdly, some generals have woken up to the fact that they cannot rely on advanced weapons and have begun to reuse formations and personal training. Fourth, the people of the south knew the cruelty of the Jin soldiers, and in order to be like the common people in the north, everyone fought hard against the enemy like the soldiers. Of course, the power of the military and civilians has been brought into full play, and almost all of them are fought to the death. Fifth, under the rule of the Jin soldiers, the north was full of mourning, and it can be said that the common people did not treat everyone as human beings, and slaughtered and looted at will. As a result, not only could the Jin soldiers not go south, but also caused some northerners to sabotage the transportation channels of the Jin soldiers in the rear. The combination of these reasons led to the fact that the Southern Song Dynasty could survive for a while.

Just when the Southern Song Dynasty and the Jin Kingdom were contending, a Mongol tribe that was stronger than the Jurchens became stronger. The Mongols were simpler and stronger than the Jurchens, and grew up almost with horses. So they ride horses almost like they walk, and really die "a people on horseback". It is said that the soldiers of the Jin Kingdom established by the Jurchen people were all cavalry, and one person, one horse, and one sword broke into the world. The Mongols, however, rode one man and four horses in turn, and a saber almost swept across Eurasia and became a generation of overlord legions. After the Mongols unified the Central Plains, they felt that they did not need the assistance of these large weapons, and they were more worried that these weapons would be used by people with ulterior motives, so Yuan Taizu Tublai Khan ordered the destruction of all large weapons. Because there were no magic weapons here, the Yuan Dynasty became a short-lived dynasty. Of course, there were many reasons for the fall of the Yuan Dynasty, not only because of this, but also because of this reason.

When Zhu Yuanzhang, Emperor Hongwu of the Ming Dynasty, fought the world, while training the quality of soldiers, he secretly asked people to copy large weapons. At that time, there were not many craftsmen who could make large weapons, but these people lived in great hardship. Zhu Yuanzhang not only gave them a chance, but also gave them a promise. "As long as I and my children and grandchildren are in one day, as long as our army survives one day, I guarantee that you and your descendants will never starve to death." This is Zhu Yuanzhang's original words, and these craftsmen were moved to cry at that time. The craftsmen rely on their crafts to eat, and the Mongolians do not pay attention to craftsmanship, so the craftsmen are almost precarious. Zhu Yuanzhang gave them a way to live, so they made a lot of large weapons for Zhu Yuanzhang. This is also one of the biggest guarantees for Zhu Yuanzhang to unify the whole country and pacify the Central Plains. After the founding of the People's Republic of China, Zhu Yuanzhang, in order to protect and continue to control these craftsmen, established a camp of craftsmen, so that the craftsmen and their descendants lived in it for generations, almost cut off from the outside world.

The reason why the Ming Dynasty was able to establish a country quickly was first because of Zhu Yuanzhang's personal efforts, secondly because of the role of large weapons, and thirdly because of the efforts of a large group of civil and military ministers. As the first hero of the Ming Dynasty and the soul of the Ming army, Xu Da, the first generalissimo of the Ming Dynasty, King of Zhongshan, once prudently raised the issue of large-scale weapons and the cultivation of the army. It is possible to propose the use and development of large weapons, but the soldiers and officers of the troops should not be allowed to rely too much on them. The army of the Ming Dynasty could not be like the soldiers of the Northern Song Dynasty, and the Ming Dynasty could not repeat the mistakes of the past. Zhu Yuanzhang certainly understood what Xu Da meant, and he also agreed with this point of view. Therefore, although large weapons are equipped, they are not allowed to be used in peacetime, and these large weapons cannot be used casually without the permission of the highest commander of the barracks. Only when it is necessary to use it can it be used normally, and these large weapons are usually managed and maintained by special personnel.

Luo Li, as the commander, gave the order to mobilize the army. The "water ghost" troops secretly set off by stealth, which is not considered a normal army, and there are a series of rules for the real army to set off. The first is to sacrifice the flag, take the oath to go to the expedition, and then set off for the destination in batches. According to the rules of the Ming army, the first army to set off was scouts, that is, scouts, whose responsibility was to explore the terrain and survey the enemy's movements. The second group set off was an army escorting large weapons. Although they set off first, they did not arrive at their destination early because of the cumbersome delivery of large weapons. Although these weapons will not be used by outsiders, it doesn't matter if they are robbed, but large weapons are the treasures of the Ming army, and if they are destroyed, the loss is not small, so they need an army to escort them. The third group set off for the main forces. These include archers, shield soldiers, and pikemen. It accounts for the majority of the strength of the whole army. The fourth group set off were cavalry and axemen, and there should have been a large army commander, but Luo Li and Jinyiwei's army set off together, so they were not among them. The fifth group set off for the Firehead Army and the Logistics Corps. Originally, the firehead army was supposed to be at the forefront of all armies and was responsible for the food of the officers and men of the whole army. However, this is a short-distance battle, and the time will not be long, so Luo Li asked the Huotou Army to cook in advance and rush to the destination with food. For this reason, the firehead army immediately cooked, and when everything was ready, they had to set off with the last group of logistics troops. Since the whole army was going to attack the property, the firehead army had to prepare not only dinner, but also supper for everyone to eat and work. In order not to attract the attention of the other party, Luo Li ordered the Huotou Army to prepare at least two meals.

After the army set off, Jinyiwei's army was also concentrated, and Luo Li took Qin Tai and others on the road. Luo Li was originally worried that Qin Tai and the others would not be able to ride horses, so he prepared a carriage for Qin Tai and the others. In fact, Luo Li only paid half of Qin Tai, although Qin Tai's brain is good, but the ability in his hand is really too reluctant. But fortunately, the society was like this at that time, civil officials were always more popular than military generals, and their brains were more advanced than their hands, so Luo Li didn't dare to underestimate Qin Tai. Unexpectedly, although Qin Tai and the others couldn't charge, they could ride horses. Qin Tai, the old drunkard master, and Zhan Xiaoxiao can ride horses, and they have also ridden horses through states and provinces to handle cases. Although Qiu Min's father and son did not ride horses often, they have learned a little about driving a carriage these days. In particular, Qiu Xiaoqiu's child temper fantasizes that he is a great general, riding a horse and commanding the army to fight. I don't know if I can be a general, and if I can lead troops in the future, but if Qiu Xiaoqiu can't ride a horse, he will be laughed at by everyone, so Qiu Xiaoqiu secretly learned a lot. In addition, Qiu Xiaoqiu is flexible and observant, so he immediately found a set of experience, and horseback riding is not a problem. Qin Tai and the others can ride horses, which not only saves Luo Li a lot of things, but also saves time.
