At this time, Dongjiang Town has undergone earth-shaking changes.

At this time, these islands have become military bases, and thousands of equipment that has not been collected overnight have also arrived one after another, all of which are well-equipped, and can be customized to the Royal Military Factory according to their own specialties and habits.

These nights were not closed, and each of them became junior officers, each of whom was responsible for leading an average of ten recruits and teaching them how to fight behind enemy lines.

Not every night is reliable, but it will be a process similar to Gu raising, and those who can survive guerrilla warfare and obtain brilliant results will be promoted. As for those who were not suitable for guerrilla warfare, they were generally killed on the battlefield and retired with wounds.

War is like a sieve, survival of the fittest, since ancient times.

Mao Wenlong planned to train for another two months, and then put the guerrilla troops into the battlefield in batches to attack and harass Jiannu and kill and injure Jiannu's living forces.

In contrast, Mao Wenlong was more concerned with the head-on battle with Jiannu in the mountains.

The eastern Liaodong region, east of Shenyang and Liaoyang, is a mountainous area, which is not suitable for large-scale cavalry operations. Fighting here, Kennu will lose the mobility advantage. However, Jiannu is not only good at cavalry, in fact, Jiannu is also good at infantry combat.

However, after the Fifth Infantry Division of the Beijing Battalion came to Dongjiang Town, Mao Wenlong immediately saw the superiority of the Beijing Battalion's combat methods in the mountainous areas.

It's just that Mao Wenlong, who has been in contact with Jiannu for many years, also saw a fatal weakness of Jingyingcun, that is, the protection of the musketeers was too poor.

The musketeers of the Beijing camp were all dressed in leather armor, and they shot at Jiannu, and they did not have an advantage at all.

Jiannu's combat method is very simple, that is, within fifty steps (70 meters), shoot the Ming army formation with heavy arrows, and then launch a charge after the Ming army formation is scattered. Jiannu's bow and arrows are not very powerful, but once its arrows are pierced into the body, it is difficult to pull them out.

The flintlock pistol used by the Beijing camp can have a devastating strike effect within 50 meters, and the range is indeed similar to that of Jiannu's bow and arrow. In the process of fighting Jiannu, there will inevitably be a situation of counterfire. Jiannu will definitely not rush up stupidly, you must know that the cavalry attacking the infantry formation with a strict formation is definitely looking for death.

Therefore, Mao Wenlong immediately decided to change the protective equipment of the musketeers, and replaced all the leather armor with the same armor and helmet as the pikemen.

Zajia's bow and arrow protection ability against Jiannu is still very good, and in the bloody battle of the Hunhe River, the battle process between the white pole soldiers and Jiannu fully proves this.

At the same time, Mao Wenlong reconfigured the long-range firepower, not only using flintlock pistols as a means of long-range attack, but also arranging archers in the phalanx to attack Jiannu's different protective equipment. The way bullets and arrows penetrate is different, after the bullet hits the target, it rolls forward, and the protection of cotton armor against lead bullets is stronger than that of armor. Bows and arrows, on the other hand, can easily penetrate cotton armor.

This is equivalent to what physical damage in the game, magic damage, if the opposite side is a kitchen knife team, just pile up armor. And if the opposite side is full of magic damage, just pile up magic resistance. And on the other side, there is both physical damage and magic resistance damage, so it's a headache, and you have to pile up health.

In reality, it is obvious that you can't pile up health, and if the Ming army has muskets and bows and arrows, it's like having both physical damage and magic damage. It is impossible for Jiannu to wear a suit of armor and at the same time wear cotton to fight. Such troops do exist among the Jiannu, but their task is mainly to be cannon fodder, used to clear the obstacles and fortifications set up by the Ming army, such as horse rejection, and their status is relatively low.

The long-range strike method of Jiannu is relatively simple, only bows and arrows, just like the kitchen knife team in the game, as long as the Ming army is equipped with armor, it can effectively protect Jiannu's long-range strike.

Compared with a traverser like Zhu Youxiao, although Mao Wenlong doesn't know any physical and magical damage, he is very familiar with Jiannu's combat methods.

At the same time, compared with the emperor, Mao Wenlong thought more about how to deal with the cavalry based on history.

China has a long history and has never lacked combat experience in using infantry against large-scale cavalry. Since ancient times, Chinese agricultural civilization has usually used the 'wild goose array' to deal with cavalry. That is, heavily armed infantry, equipped with a large number of long-range strike equipment, and then arranged in a tight formation, while arranging cavalry on the left and right flanks.

When the enemy cavalry attacked, shoot the enemy cavalry with a long-range strike unit in the infantry, and if the enemy cavalry formation is disorganized, throw the cavalry into a charge, and the battle can be won.

If the enemy cavalry and infantry shoot, then use the advantage of the armor protection on the infantry to fight for consumption, the bow and arrow used on horseback, the power is certainly not comparable with the infantry's strong bow and crossbow, and in terms of protection ability is certainly not compared to the infantry, the heavy cavalry on the horse's endurance consumption is relatively large, it is impossible to shoot with the infantry. Therefore, long-range shooting, infantry is absolutely advantageous.

If the enemy cavalry launches a frontal charge, it is definitely looking for death. Cavalry units usually choose to go around and blast chrysanthemums, or disrupt infantry formations with long-range strikes before charging.

The apocalypse phalanx created by Zhu Youxiao actually has such a function.

The spears are like a forest, and the cavalry doesn't dare to rush when they see it, even if they rush over, the war horse will stupidly crash into this hedgehog? Even the best trained war horses will instinctively slow down when they rush in front of the spear formation that is waiting for them. As soon as the cavalry rushes forward without a speed advantage, it will be poked to death in minutes.

Long-range strikes have musketeers, which are not fundamentally different from the traditional wild goose formations.

It's just that Zhu Youxiao didn't know much about Jiannu's combat methods, so he copied the Westerners' set in the protection of musketeers. It's just that this set is obviously not suitable for the Ming Dynasty.

Mao Wenlong, who intended to change the equipment, was a little apprehensive, after all, this was a tactic set by the emperor himself, and if he wanted to change it, would it make the emperor unhappy?

However, to Mao Wenlong's delight, less than half a month after the release of the concerto, Zhu Youxiao approved and agreed to Mao Wenlong's proposal.

Soon, all the leather armor on the musketeers of the Fifth Infantry Division of the Beijing Battalion was replaced with armor, and at the same time, Mao Wenlong also increased the archer configuration in the phalanx. The soldiers and civilians of Liaodong are physically strong, and there is never a shortage of people who can shoot bows. There are still many excellent archers, and there are even more recruits who can be trained as archers.

Zhu Youxiao was still self-aware, and he himself had some doubts about whether this kind of phalanx could adapt to the battlefield, so he let the Fifth Infantry Division go to the Liaodong front to test the water first. Mao Wenlong's performance asked for a change, and the reason was clear, Zhu Youxiao naturally would not veto it, and readily agreed.

The emperor's open-mindedness and full support made Mao Longwen more confident. With the new army of the Fifth Infantry Division of Jingying, it is completely unintimidating in the mountainous areas.

Fighting in the mountains, Jiannu's cavalry had no way to charge around the rear, so they could only shoot and charge head-on with the Ming army. So, what else is there to be afraid of?

Moreover, the emperor has already indicated in the holy decree that even if the casualty ratio with Jiannu is 2:1, it can be regarded as earned. Jiannu has to continue to absorb Jurchens at that point of population, and if more people die, they will break their muscles and bones. In contrast, Daming has a huge population and is not afraid of such losses at all.

With sufficient personnel and equipment, Mao Wenlong immediately sent the first batch of guerrilla troops to Liaodong in July of that year, and this group of guerrilla troops numbered 500 people, divided into 10 squads, and launched attacks on Jiannu in different regions.

The main purpose of these guerrilla troops is to accumulate experience in raiding and harassment, so that they can better train other guerrilla troops and pave the way for all-round raids and harassment.
