In fact, this batch of Hong Wu Gong is already a new model that has undergone a series of improvements. In the past, Zhu Su and Mu Ying improved gunpowder and firecrackers in the Prince's Mansion, and Zhu Su once put forward the concepts of "flintlock pistol" and "breech cannon". Those concepts are either because they are still being explored, or because the technology is not yet supported, or simply because they are too expensive, and the Ming Dynasty does not have sufficient treasury now, so it has not been put into use.

But in addition, Zhu Su also pointed out some methods that would be easier to improve the power of existing firearms, such as "paper-wrapped gunpowder" and "wooden horses".

The so-called "Trojan Horse" is to press a special piece of wood between the gunpowder and the gun, so that the medicine chamber is better sealed, and the explosion produces greater pressure, increasing the rate of fire and the range of the gun.

Although in the course of the development of the firebolt, this is only a stopgap measure. But it is undeniable that this is the cheapest and easiest improvement that the Ming army can now achieve on a large scale in a short period of time. All that was needed was to stuff an extra piece of wood of the right size with a pre-polished piece of wood when it was being filled.

Don't underestimate this small piece of wood, in history, it was not until the eighth year of Yongle that the Ming Dynasty learned about the improvement technology of this fire gun from the hands of the Annan people. The improved firearm doubled its power, which directly prompted the Yongle Emperor to make up his mind to establish the famous "Shenji Battalion", and to develop firearms as a major war weapon of the Ming Dynasty.

"Trojan Horse", "Paper-wrapped Gunpowder", and "New Gunpowder Ratio", these three seemingly insignificant improvement methods are enough to make the originally quite chicken fire gun in the Hongwu period enough to shock the Yuan court veteran like Tabin Timur, and bring a lost scientific and technological shock to this Mongolian cavalry.

Coincidentally, when Naha broke through the pass and Jizhen chose to shrink its defense, most of the firearms that the Ming army had too late to take away from the warehouses of many guards were confiscated by Naha. However, after Naha broke through, he didn't fight any tough battles, and only tentatively attacked the walls of Yongping Mansion a few times.

Siege warfare firearms are useless, and Nahachu, who is a Yuan person, also advocates cavalry archery more and is not interested in firearms, so these new firearms, which should have belonged to the soldiers of Jizhen, were not used by the Yuan army.

These tens of thousands of firearms snatched from Daming have become chicken-like existences. And this time, Guan Tong attacked Changli, with the mentality of trying it out, and brought these fire guns from Daming. originally thought that if the Ming army dared to go out of the city to face the battle, it would be better to let him go first and then use it as a burning stick.

Unexpectedly, they were trapped at home and abroad overnight, and were wiped out by Zhu Di and Zhang Yu's thunderous army, and these firearms were transferred to Zhu Su's Ming army.

These firearms were changed according to Zhu Su's opinion, how could Zhu Su not know their power? Wu Wangwei was immediately ordered to take these firearms. The Ming troops under Cao Yuan have always practiced according to Wu Wangwei's standards, although they have not let go of the new-style firearms, but they have also used the old-style firecrackers to practice the three-stage attack with Wu Wangwei. Now in a hurry, together with Di Meng's Wu Wangwei, he formed a three-stage attack camp.

Fortunately, these Mongolian cavalry have been peaceful for a hundred years, and they are no longer as brave as their ancestors, although the momentum of the charge is still devastating, but in the face of unexpected attacks, they still hesitate and timidly for a moment after all. As soon as the momentum of the charge was slightly blocked, they missed the opportunity to defeat Zhu Su's Ming army in one go.

Originally, it was the first time to use this method to deal with the enemy, and Wu Wangwei, who had little confidence, and the Ming army under Cao Yuan gradually cooperated more and more tacitly, and the frequency of firing guns gradually became higher and higher.

"This ...... ...... go on like this."

If it was the Dayuan Iron Hoof a hundred years ago and encountered such an unexpected situation, I am afraid that the first reaction would be to cover the head and rush first. After all, this Ming army was only 10,000 people, and although they were divided into troops, the number exceeded 20,000.

Even if you use corpses to pile up, you can also bulldoze these Ming troops hard.

But now, Tabin Timur and his cavalry retreated. Seeing that the companions in the front row continued to fall in the pungent smoke and whistling lead pellets, many Mongolian cavalrymen reflexively pulled up the reins of their horses, wanting to turn their horses' heads and flee backwards. However, how could the momentum of tens of thousands of cavalry be stopped so easily? As a result, the rear army continued to collide with the front army, and the front army continued to reap life by the roaring fire of the Ming army.

No wonder they have a low fighting spirit. They were originally "guest troops"! It's because it's profitable, and it's just an army that Naha wants to "get a handful".

As the "Shanyang Wanhu" who lived in the middle of the three parts of Dayuan, Daming and Naha, and then surrendered directly to Daming without any moral pressure to become "Duoyan Sanwei", they did not have much loyalty to Dayuan or Naha. In addition to profits, the first priority is how to preserve strength in the three-way melee and sell at a price.

It is precisely because of this that when they were besieging tens of thousands of Ming troops under Guo Xing's department, they would use the method of "cavalry shooting" to far consume their strength, leaving the tough battle to Naha's army to gnaw.

When there is a bargain to be taken advantage of, they are naturally indomitable. But now that he has encountered a hard bone, from Tabin Timur as the main general, to the ordinary cavalry who is charging, there are only four words left in his mind: save your life!

"Woo, woo!" The low sound of bull horns sounded, and the Mongol cavalry, which had finally stopped their advance, began to retreat. Zhu Su looked at the cavalry who were retreating like a tide, and even forgot to pick up the folding fan in his hand when it fell to the ground, but wiped his sweat with a pale face.

He admitted that he had gambling elements in this battle, but in the end, he made a lot of money: with only a few thousand people, he really shocked tens of thousands of cavalry troops, and temporarily gained a firm foothold in this meat grinder!

Brother Mu's three-stage attack is really good!

"Fifth Highness, what should I do next?" Di Meng, who was in charge of coordinating the firecrackers, still had a worried look on his face. "Our purpose is to rescue Gongchang Hou Guo Xing, who is still under siege."

"But most of our troops are foot soldiers. Although the Mongol cavalry retreated, if they were to pursue themselves, these Mongols would surely show their best horse archery and shoot our pursuing troops into a sieve. ”

"But if you don't move forward, how can you join forces with Gong Changhou, and then break out of the encirclement together?"

Although Di Meng's words were a request for instructions, they also reminded Zhu Su not to forget that the situation was still difficult. Zhu Su glanced at the subordinate general who was gradually growing, noticed the gazes of the sergeants around him, and in order to appease the morale of the army, he pretended to be indifferent and picked up the folding fan that was already dirty on the ground.

Unfolded the fan, but the fan made himself disgraced, so he had to pretend not to care and silently close it, and then said with a smile: "You don't have to worry, this king has already thought about this." ”

"As long as the Yuan army changes from 'defeated and fleeing' to 'routing', they will no longer have the energy to take care of us and the Ming army under Gong Changhou."

As he spoke, he turned his head to look at Zhu Di: "Fourth brother, how is it?" ”

Zhu Di's face was also blackened and whitened by gunsmoke, but his face was still serious, sitting on his horse and watching the situation ahead with a monocular. Hearing this, he waved his hand back slightly: "Not yet, I still have to count it." ”

"Ten, nine, eight, seven...... That's it, give the number! ”

Zhu Su's face turned pale when he heard this, and he nodded to the dog beside him. The dog understood, and immediately shot an arrow into the sky, and a scream of "snort" suddenly resounded throughout the battlefield.

"Kill!"

After the side slope of the Mongolian cavalry that was fleeing, a Ming cavalry with a number of thousands suddenly came out, with a black horse in the crotch of the leader, carrying a cooked copper Zen staff, and a bald head shining in the sun, which was Zhang Dingbian, the "world's first fierce general"!
