Under the enthusiastic gaze of everyone at the scene, the marching musket battalion and the infantry battalion queue invariably changed, each divided into five, and broke down into five detachments.

Thus there were five musket battalion formations and five infantry battalion formations, each with six hundred men.

Just when people were wondering about this, the five detachments of the musket battalion and the five detachments of the infantry battalion were combined in pairs to form five mixed formations of musketeers and infantry.

Each mixed army formation was 1,200 men, of which the phalanx of 600 pikemen of the infantry battalion was in the middle, and the musketeers of the musket battalion formed a phalanx of 300 musketeers on each side of the pikemen.

Among them, the pikemen phalanx consisted of fifty men per platoon, for a total of twelve platoons.

The phalanx of musketeers also had fifty men per platoon, but since it was divided into two parts, the left and right sides of the pikemen, there were only six rows, but there were as many as one hundred musketeers per row.

In the musketeer phalanx, six rows of musketeers were divided into three groups of two each, with the front row of musketeers in a kneeling position and the rear row of musketeers in a standing position.

When engaging the enemy, the first group of musketeers in front of them fired and retreated to the rear to reload, the second group of musketeers in the back of the line stepped forward and continued to fire, and the second group retreated to the rear after firing, and the third group of musketeers was on top.

In this way, when the third group of musketeers finished firing, the first group of musketeers had already completed the installation of ammunition and could take over the third group of musketeers for shooting, so that the three groups were repeated to provide uninterrupted fire killing, which is the famous rotational reverse reloading method.

The reason why Li Yuntian adopted such a hybrid method was to maximize the power of the musketeers while ensuring the safety of the musketeers, and then to contain the enemy's troops, especially the enemy's cavalry, from charging.

Not only is this hybrid formation fierce, but it also has the flexibility to change sides, so you can calmly deal with enemy forces that charge from the front or surprise from both sides.

Although the Musketeer phalanx was flanked on either side of the pikemen, its position was not fixed, and it was possible to advance or retreat to the front or rear of the pikemen to form a new phalanx, or to assemble on the pikemen's flanks.

This increases the frontal attack power of the musketeer phalanx, so that all soldiers can concentrate their fire on the front of the phalanx.

On the front of the phalanx, the musketeers could fire unhindered, and if the enemy rushed to the front and rear pikemen either defended or held their ground, the musketeers retreated to the rear of the pikemen phalanx and reformed into a new phalanx, thus continuing to export firepower.

Although it seems that the mixed military formation designed by Li Yuntian is very simple, it has gradually evolved into this formation after more than 100 years of war in history, during which it has experienced the famous Spanish phalanx and the Dutch Morris phalanx.

It was the first time for the people at the scene to see this strange formation, so they were immediately attracted by it, and looked intently at the five mixed formations in the field.

The five mixed formations moved rapidly, constantly changing formations, seemingly chaotic but in fact orderly, and soon the formation was set up in the field, showing a checkerboard grid like the chessboard formation of the Roman legions, that is, two mixed army formations in front and three mixed army formations in the rear.

The reason why Li Yuntian made the five mixed army formations appear in a checkerboard grid shape was to avoid sudden attacks on the flanks and rear of the military formation, so that he could respond at the first time, which can be described as both offensive and defensive.

Just as people were privately discussing how the next drill would go, there was a sudden noise at the foot of the hill opposite the five mixed army formations, and more than two hundred horses were driven by a group of cavalry of the Xiaowu Army and stopped at a distance of six or seven hundred meters.

Seeing this, Li Yuntian nodded to a military attache on the side, and the military attache bowed and waved his hand to a non-commissioned officer of the Xiaowu Army standing on the top of a hill not far away, and the non-commissioned officer waved a large flag in his hand at the cavalry of the Xiaowu Army who rushed to the horse.

Seeing the banner shaking, the cavalry of the Xiaowu Army immediately drove the more than two hundred horses to rush towards the five mixed army formations in front.

At the same time, the five mixed formations also changed, and the musketeers, who had been on either side of the pikemen, quickly stepped forward and assembled in front of the pikemen phalanx to form a new musketeer phalanx.

After forming a formation, the musketeers in the front row were half-kneeling on the ground, and the musketeers in the second row aimed their guns at the rushing horses, while the four musketeers in the back were ready to attack.

Although there were five mixed formations in the field, due to the checkerboard arrangement, only the two mixed formations in front were able to meet them, and the remaining three mixed formations in the rear were actually on alert.

When the cavalry of the Xiaowu Army drove the more than 200 horses to a distance of three or four hundred meters away from the two mixed army formations, they all pulled the reins of the military horses under their seats and flashed to both sides, leaving only the frightened horses roaring forward, the sound of horses' hooves rumbling, the scene looked quite spectacular, quite a cavalry charge.

This made the people at the scene suddenly nervous, once they were hit and trampled by the high-speed galloping horses, the soldiers of the two mixed army formations in front of them would inevitably cause a lot of casualties.

Bang, bang, bang......

However, when the horses were more than a hundred meters away from the two mixed formations, the musketeers in the first two rows of the army pulled the trigger.

After a dull burst of gunfire, dozens of horses running in front of the herd fell to the ground with a wail like harvested wheat, trampled by the horses coming from behind, and suddenly the flesh and blood were blurred, and blood was splashed everywhere.

The first two rows of musketeers immediately retreated, and the third and fourth rows of musketeers rose up and continued to fire at the galloping horses, followed by the fifth and sixth musketeers.

By the time the musketeers of the fifth and sixth platoons had fired their projectiles, there was not a single horse standing in front of the two formations, and all the rushing horses had been hit in the three rounds of fire just now, and they all fell in pools of blood, some dead, some convulsive and let out a low wail.

This made the atmosphere at the scene a little depressing and depressing, and people looked at the scene in front of them in amazement, especially the leaders of the Jurchen tribes were even more shocked, no one expected that the more than two hundred horses would be killed by the musketeers so quickly.

It is especially important that after the 5th and 6th platoons of musketeers fired, the first and second platoons of musketeers took over from the 5th and 6th platoons of musketeers in an orderly manner after the ammunition had been installed, which meant that the mixed formation already had the ability to fire non-stop.

This is a very terrifying thing, and if the battle continues like this on the battlefield, I don't know how many cavalry and infantry will die in the rain of bullets and bullets in the mixed army.

This also complained that everyone at the scene was shocked by the scene in front of them, after all, no one had ever seen such a powerful firearm before, and the Shenji Battalion of Emperor Yongle when he was in the north of Mongolia was nothing compared to the musket battalion of the Xiaowu Army, and the difference in power was huge.

"Oh~~"

After the initial consternation, the Xiaowu Army sergeant at the scene was the first to react, raising his arms excitedly and shouting.

Driven by the Xiaowu army, the Liaodong Ming army and the Jurchen soldiers also cheered: With such powerful firearms to help, how could the Mongol army be undefeated?

A smile appeared on the corner of Li Yuntian's mouth, and he quietly glanced at the leaders of the Jurchen tribes who were shocked at the scene, and then left surrounded by Gu Liyu, Pei Jun and others.

Today's drill of the Musket Battalion has successfully achieved the effect he wants, and presumably the leaders of the Jurchen tribes will be honest after experiencing this incident, so as to save any unnecessary trouble in the future.

In fact, Li Yuntian originally wanted to integrate the 5,000 cavalry brought by the Jurchen tribes this time into a centralized use, because they had lived between the white mountains and black waters for a long time, and the harsh living conditions had caused the Jurchens to have strong combat effectiveness, both men and women could fight on horseback, and they could produce when they dismounted, so the combat effectiveness of the cavalry was comparable to that of the Mongols.

It is a pity that due to the mutual suspicion between the Jurchen tribes and the wariness of the Ming army, Li Yuntian had no choice but to give up this plan and had to use the Jurchen cavalry separately, unable to charge into battle and could only cooperate with the infantry.

Just as Li Yuntian had thought before, under the deterrence of the musket battalion, the soldiers of the Jurchen tribes became honest and obediently drilled according to the instructions of the military attache of the Xiaowu Army.

Compared to the leaders of the Jurchen tribes, he was even more shocked to witness the mixed army formation of musketeers and pikemen at the scene who shot the horses without much effort, if the cavalry of the Mongols were proud of this mixed army formation, then he was afraid that he would be slaughtered, and he would never have imagined that the Ming army would have such powerful firearms.

Therefore, after returning to his residence in Kaiyuan City in the evening, Halbara drank sullenly, although he now belonged to the Ming Dynasty, but as a Mongol, he really could not sit idly by and watch the Mongol cavalry be mercilessly harvested by the musket battalion when they fought against the Ming army.

Li Yuntian took good care of Halbara, and specially asked people to find him a comfortable mansion in Kaiyuan City for his mother to live in, and treat and recuperate in it.

"I heard that a drill was held outside the city today, and Daming's firearms killed hundreds of horses in an instant, is there such a thing?"

Soon after, the door was pushed open, and a handsome girl walked in with a middle-aged woman, both of whom were dressed in Mongolian costumes, with a lot of ornaments on their bodies, and walked with a crisp sound, and the middle-aged woman saw that Halbara was drinking alcohol, so she asked with a smile.

"Eji, this matter is true, Daming's firearms are very powerful, and those horses were shot before they rushed to the front of the formation."

Halbara hurriedly got up and helped the middle-aged woman to sit in the seat, the middle-aged woman was his mother Gegentana, whose name means "pearl" in Mongolian, and the handsome girl was Nomin who had washed her cheeks.

After Halbara's father was killed, the Dayan tribe was supported by Gegentana, a woman with both perseverance and wisdom, who led the Dayan tribe to avoid the pursuit of the enemy and get out of the trough, so Gergentana has a high prestige in the Dayan tribe, and the Halbara brothers are very filial and respectful to him.

"Tell Eji about that Lord Liu." Gegentana frowned slightly when she heard this, and said with a smile, the Lord Liu in her mouth is Li Yuntian, and Li Yuntian still uses the pseudonym "Liu Fang" used in the Korean Kingdom after coming to Liaodong.

"Lord Liu is a fair person, treats all the people in the city equally, and is a person worthy of respect." Halbara pondered for a while and then replied, since he and Li Yuntian hadn't been together for a long time, he didn't know Li Yuntian very well, so he could only start from his own personal feelings.

"To have such a powerful firearm, this Lord Liu is not simple!" Gergentana smiled slightly, quietly reminding Halbara.

If she remembered correctly, even the high-ranking and powerful Duke of Yiguo in the Ming Dynasty did not carry such powerful firearms, but Li Yuntian brought thousands of them to Kaiyuan City, it was obvious that Li Yuntian had a deep background, otherwise Emperor Xuande would not have given him those firearms with peace of mind?

What's more, Li Yuntian exchanged prisoners of war with the Mongolian army in Yinzhou City without informing Zhang Hao, the chief soldier of Yiguo and Liaodong, and co-opted the Jurchens with great fanfare, which showed more courage than ordinary Ming officials.

Therefore, Gegentana concluded that Li Yuntian was Emperor Xuande's confidant official, but she still did not know Li Yuntian's identity, but it was certain that she was in the Ming Dynasty and had a high position, which was crucial to the future development of the Dayan Ministry.
