While training, Ma Mingfeng was not idle. He first learned about the firearm technology of the Ming Dynasty at that time, and then used his brain to prepare for the development of new weapons.

Of course, it was impossible to develop too advanced weapons under the conditions at that time, but it was still not a big problem to use the knowledge of later generations to make some improvements.

After some understanding, Ma Mingfeng learned that the technology of a fire-type musket had appeared at that time, but it was not widely used. Some people also developed the technology of binding spears on the musket, which was not taken much attention.

And just happened to be in a corner of Kaifeng Prefecture, Ma Mingfeng discovered a book "Military Artifacts" introducing the technology of Suifa Musket Manufacturing.

This made Ma Mingfeng very excited. He immediately found a craftsman who produced firearms and ordered them to study this work and try to produce a firearm.

At the same time, Ma Mingfeng ordered the blacksmith to create an eight-inch-long sharp knife. This knife was extremely sharp but unique in shape. What was particularly unique is that its handle was narrow and short, and it had holes, which seemed to be tied to certain objects.

Of course, these are just research work, and it is difficult to achieve results in three or two months. What Ma Mingfeng is most urgent now is to be able to mass-produce weapons with high lethality.

For this type of weapon, the most cost-effective ones are naturally mines and grenades.

Landmines such as landmines had already appeared at that time. As early as the Battle of Jingnan, early landmines were used in the Battle of Baihegou. In the middle and late Ming dynasties, landmines were used more widely. In Qi Jiguang's fight against Japanese devils, landmines played a significant role. However, it is strange that since then, landmines never played a very outstanding role in combat.

However, in later generations and reading history, Ma Mingfeng knew deeply about the role of landmines in the two world wars and various wars, especially in the process of defending cities, the role played by landmines cannot be ignored.

At this time, this picture often appears in Ma Mingfeng's mind: "When the thief army broke into its own minefield, without any warning, the mines in the minefield suddenly exploded, and there were wailing one by one, and the thief army suffered heavy casualties..."

Whenever Ma Mingfeng thinks of such a picture, he feels that the picture is really beautiful.

At this time, the technology for producing landmines in the Ming Dynasty was quite mature, and the technology for landmines was relatively simple. It could cultivate a group of experienced people in a short period of time, and the raw materials were not difficult to find. In addition, the cost was not high, so it was very cost-effective. However, people did not pay much attention to it at that time, which was mainly related to the passive defense of landmines and the small damage of single shots.

However, this is not a big problem for Ma Mingfeng, because he can greatly improve the lethality of landmines, because he knows that there is a kind of mine jumping, which has a boosting device. When the local mine is about to explode, it can jump out of the ground about one meter before explodeing. Its power will naturally be much greater than that of mines that only explode underground.

As for the booster device, it is not difficult. Its principle is similar to that of the early gunpowder weapon rockets, which is the most basic thing for those craftsmen who make firearms.

So when Ma Mingfeng told the firearm craftsmen about this "thunder jumping" method, everyone was shocked. They never expected that there would be such a mine manufacturing method. They deeply believed that as long as this lightning jumping could be developed and mass-produced, it would definitely cause huge harm to the thieves.

While these firearm craftsmen were ecstatic, they also deeply admired Ma Mingfeng. They really didn't expect that someone would have such a genius idea. Once this mine was successfully developed, they would not only leave their reputation in history, but also receive rewards. It was simply a good thing to gain both fame and fortune.

The most important thing is that such landmines are easy to develop and do not have much complex design. These firearm craftsmen are expected to be successfully developed in at most ten days and half a month, and they can produce large-scale Buddhas in another half a month.

The development of things was indeed as expected by these firearm craftsmen. Ten days later, the jumping of lightning was developed. Ma Mingfeng ordered people to test this jumping of lightning, and found that its power was indeed much greater than ordinary landmines.

Then these firearm craftsmen began to cultivate their skilled skills and finally achieved mass production within half a month.

Of course, even if this kind of landmine is produced at the most, it only considers a passive defense situation, and the scope of use is limited. Even if it is mass-produced, Ma Mingfeng thinks that at most it is only enough to produce three or five thousand pieces.

So in addition to landmines, there is a new weapon of destruction.

So Ma Mingfeng thought of the grenade.

In fact, the principles of grenades are similar. They are all ignited by external forces to ignite gunpowder installed in confined space, causing explosions, thereby generating destructive and lethality.

But the difference is that although the lethality of grenades is not as good as mines, they can be used more conveniently and flexibly. Unlimited areas of use, they do not necessarily have to be used for passive defense.

So when Ma Mingfeng introduced this grenade to the firearm craftsmen, these firearm craftsmen were stunned. They never expected that this prefect was indeed a genius and could have thought of such a clever weapon.

So when the prefect painted the structural diagram of the grenade, the firearm craftsmen suddenly felt excited and immediately separated a few people to "develop" this grenade according to the structural diagram provided by Ma Mingfeng.

In fact, because the basic principles of this grenade are highly similar to those of landmines and the materials they make are simple, people have successfully developed it in just five days.

After Ma Mingfeng received the news, he was naturally ecstatic. He immediately ran to the craftsman and skillfully removed the remaining grenade from the ring, and then threw it into the distance. With a bang, the grenade exploded a small pit more than one foot deep, and also destroyed a stone around the pit.

This shocked the onlookers. A small grenade had such powerful power that even a stone could explode, let alone a flesh and blood body?

The outcome of the later was naturally unnecessary. This kind of grenade quickly began to produce quantitatively, and its production speed was faster than that of landmines, and tens of thousands of grenades were quickly produced.

At this time, Ma Mingfeng also decisively suspended the hot training operation. After discussing with Yu Zhenlong, he decided to add a bomb drop exercise to the original training course.

Of course, the grenades used by Ding Zhuang, who were training soldiers, were all in shape and were not filled with gunpowder. When the bomb drop practice was almost done, Ma Mingfeng would order people to teach the actual grenade usage procedures.
