"There are many types of guns, I don't know what kind of guns the chief soldier wants to cast."

Bo Yu frowned slightly, looking a little hesitant, and after muttering for a while, it seemed that he had made some decision in his heart, and then spoke.

"With all due respect, the Hongyi cannon is expensive, and although it has a remarkable effect on attacking the city and destroying the wall, it is not practical to use it in battle artillery battles."

"The Hongyi cannon often weighs more than thousands of catties, is extremely cumbersome, extremely difficult to transfer, difficult to load, extremely slow to fire, and flashy."

Bo Yu's expression was solemn, he bowed slightly, and said in a deep voice.

Chen Wang's eyes moved slightly, Bo Yu's opinion was undoubtedly a heresy among heretics at this time.

At the end of the Ming Dynasty, in fact, the Ming army had already clicked on the wrong technology tree.

In the early and middle period of Chongzhen, there was a craze for buying Hongyi cannons, ranging from small Hongyi cannons to large heavy cannons, with prices ranging from at least 100 taels to thousands of taels.

The largest Hongyi cannon even weighed 7,000 catties, and the shells alone weighed 23 catties.

In the Ming Dynasty, one pound was almost equal to 600 grams now, and one pound was about 450 grams, and when the two were converted, the cannon that was fired weighed 30 pounds.

A thirty-pounder gun can be called a heavy gun in a naval gun, let alone on the road.

Not to mention the cost of the Hongyi cannon, it is difficult to form dense vitality with its rate of fire and slow reloading, and it has a limited killing effect on men and horses, so it is already not suitable for land warfare.

Moreover, at the time of the land war, the two armies fought in formation, and the two formations strangled each other and attacked each other.

Naturally, the artillery can't hit just one place, and this exposes another shortcoming of the Hongyi cannon - slow turning.

The situation on the battlefield is changing rapidly, and because the Hongyi cannon is slow to turn, it is often impossible to provide fire support in a timely manner.

I think that the above shortcomings, the role played by the Hongyi cannon in defending the city and in the field is not great, which does not mean that the Hongyi cannon is not good.

After all, such a heavy artillery was not designed for field warfare and defending cities, it was originally designed for the confrontation between ships at sea, and ...... Siege the city!

However, in the current situation in the north, where does the Ming army still have the strength to take the initiative, only the Qing soldiers have always attacked the city.

In April of the sixth year of Chongzhen, Kong Youde led the rebels and their families to defect from Dengzhou, Shandong.

The consequences of Kong Youde's defection were extremely serious, and even laid the groundwork for the subsequent fall of the Ming court.

When Kong Youde defected, he not only brought more than 20 Hongyi cannons, but more importantly, he also brought over the fleet, cannon casting craftsmen, and elite gunners that Houjin urgently needed.

It is precisely because of Kong Youde's defection that the ability of the Later Jin and later Qing troops to attack the city has been greatly improved.

The Qing court attached great importance to firearms and artillery, and not only formed a firearms unit called "Wuzhen Chaoha", but even began to implement firearms and artillery on a large scale in the army.

The Ming army was also affected by the Qing army's large number of Hongyi cannons, and also began to cast a large number of cannons, and the two sides continued to innovate their own equipment and weapons for more than ten years.

This is also why, at the time of the Battle of Songjin, the Ming and Qing dynasties used artillery and firearms even to a terrifying extent.

In many cases, the fiercest battles between the two sides are not when they are in close combat, but when the artillery is fighting each other.

"Originally, these guns were all heavy artillery used by Hongyi for ships at sea, and they were not suitable for land field battles and marches."

Bo Yu didn't notice the change in Chen Wang's expression, and was still sincerely persuading.

"The students don't recommend that the chief soldier cast such a heavy artillery."

"Moreover, the craftsmen who followed the students to make cannons at the beginning basically stayed in Nanzhili, and only more than ten people came with them, just to make Hongyi cannons, and it will be difficult to build them for a while."

Chen Guang's first task when he went to Nanzhili was to invite Bo Yu, and in addition to that, there was a secondary task, which was to recruit craftsmen who could cast cannons.

However, it is very troublesome to recruit artillerymen, after all, the craftsmen who can cast cannons at this time are all military craftsmen, although Chen Guang has a lot of money, but it is difficult to spend money without a way, and these things cannot be put on the table.

Some of the cannon casting craftsmen who came to Hanzhong Mansion with Bo Yu were Bo Yu's students, and some were craftsmen who were familiar with Bo Yu, and it cost a lot of money to bring them together.

"Mr. Bo doesn't need to worry, I didn't plan to build a Hongyi cannon in the first place."

Chen Wang never thought about building Hongyi cannons from the beginning, and the best field land artillery at this stage is not the heavier the better.

Bo Yu's frowning brows stretched slightly, when he cast cannons for Zhang Guowei, Zhang Guowei's first request was to build Hongyi cannons, requiring the bigger the artillery, the better, all used to defend the city.

His several persuasions ultimately yielded no results, and he was worried that Chen Wangye would also insist on building Hongyi cannons, which would be useless to spend money and silver.

Chen Wang's words made Bo Yu's hanging heart relax slightly,

"I would like to ask Mr. Bo to cast a cannon, first of all, it is light and strong, the weight should not be too heavy, it is best to be easily pulled by four or two horses, and it can be pushed and transferred by the artillery after entering the battlefield."

The field artillery on land should not attack the strong city walls but the enemy soldiers, and if they were against the Qing soldiers, they only needed to consider their shield vehicles.

The caliber of the land artillery does not need to be too large, the power is sufficient, and it is best to be able to easily travel with a few horses.

After entering the battlefield, the artillery can push forward, the focus is to be able to quickly adjust and aim and steer, reload quickly, and the rate of fire should also be high, so as to be able to quickly provide fire support.

According to the caliber of the European continent during the Napoleonic Wars, the land artillery was generally in the four orders of magnitude of three pounds, six pounds, nine pounds, and twelve pounds.

However, the Napoleonic Wars were already in the nineteenth century after all, and the question of the weight of the cannon casting process was considered.

As it stands, a twelve-pounder cannon is not necessary, and a heaviest nine-pounder cannon will be sufficient for most cases.

Chen Wang has memories of being in Liaodong, there are a lot of Hongyi cannons in Liaodong, and he has not seen them.

Xu Guangqi once ordered a large number of Hongyi cannons weighing ten catties from Westerners, which were converted into pounds, which were almost thirteen-pounder cannons, and these cannons were later transported to Liaodong.

The cannons were so heavy that they required more than six horses and mules to pull them, and they struggled to keep up with the marching troops.

"I plan to make three specifications of artillery as fire support at the bureau, department, and battalion levels."

"Artillery at the bureau level should be able to shoot three catties of artillery, five catties at the ministry level, and seven catties at the battalion level."

Converted into pounds, the bureau level is almost a four-pounder gun, the department level is almost a seven-pounder gun, and the battalion level is almost a nine-pounder gun.

Chen Wang did not completely apply the data, firstly because it was inconvenient to convert, and secondly, because according to the standards of the European continent, the power of the three-pounder gun might not be enough to deal with Houjin's shield car, and if it was increased to a four-pounder gun, it would be more reliable.

"It's not difficult for the chief soldier to ask for the cannon to be cast, and a sample cannon can be made soon."

Bo Yu's eyes lit up slightly, and his hanging heart finally let go, and a smile appeared on his face, and he spoke.

"According to the requirements of the general soldier, the bronze cannon is the most suitable, and the cannon body is much lighter than the bronze cannon."

Bo Yu put his mind at ease, and Chen Wang also let go of his heart.

He had spent more than two years on the copper hairlocks that he had seized, and they were already unusable.

Not to mention the heavy weight of those guns, although with the help of the new gun carriage is much easier to transport, there are still a lot of troubles.

"By the way, I have encountered a problem here, now the artillery in our army uses firecrackers, and after dragging the artillery cart forward for a long time, the artillery cart has problems in many places, so it can only stop and rest and intensify, is there any way to solve this problem."

Chen Wang didn't know why he directly copied the gun carriages made during the Napoleonic Wars in later generations, and these problems appeared, and after hesitating for a while, he still asked questions.

To Chen Wang's surprise, Bo Yu gave a solution after pondering for a while.

"The new type of gun carriage developed by the general soldier has been used in many places, and the bolt of the gun carriage and the iron sleeve cover the gun tail bead, which can adjust the height of the gun muzzle, and with the front sight and the door, you can quickly aim."

"If you need to multi-day Mercedes-Benz to turn in, there may be problems at the joint, it should be caused by long-term marching shaking, and installing some shock absorption measures should solve the problem."

Chen Wang's face was slightly condensed, he thought about a lot of things, but he forgot about the problem of shock absorption, in the end, it was still dark under the lamp.

"Mr. Bo helped a lot this time and solved the problem that had plagued me for a long time."

Chen Wang hugged his fists and said with a smile.

Bo Yu also smiled, returned the salute, and said modestly.

"The chief soldier is gifted and intelligent, not only can lead the troops to fight, but also has a deep study of ordnance and weapons, and has many unique insights."

"This time, the students just can't come up with a solution, and the chief soldier can solve the problem with some time."

Bo Yu's words are modest and polite, and the flattery is not embarrassing or offensive, in fact, it is also a science.

However, Chen Wang did not forget what he wanted to do with Bo Yu.

"In addition to casting cannons, there are two other things that also need Mr. Bo's help."

Bo Yu bowed slightly, and said with a straight face.

"If there is something that requires the students to contribute, the chief soldier can speak out, and the students should do their best."

Chen Wang raised his hand and spoke.

"These two things don't require much energy from Mr. Bo, and the future will take a long time, and Mr. Bo is still focusing on taking care of his body first."

"The first thing is about the firecracker, I wonder if Mr. Bo has not heard of the self-generated firecracker?"

"Self-generated firebolts?"

Bo Yu frowned again, frowning is a habit of his, and he usually subconsciously frowns when he begins to recall and think about problems.

Chen Wang saw that Bo Yu was caught in memories and thoughts, and he was not in a hurry.

In the middle hall, someone had already made tea and put it on the table.

Chen Wang unhurriedly picked up the tea in front of him, lifted the tea lid and took a sip, patiently waiting for Bo Yu's answer.

Chen Wang didn't wait long, and Bo Yu had already opened his mouth to give an answer.

"In case of wind and rain, it is inconvenient for the gun, and all the guns must open the fire door first, but they can be raised against the enemy."

"There are often those who are wet by wind and rain and can't make a haircut, and there are those who don't shine on the stars and send them by mistake."

"The faucet must be transformed into a message, so that the flint touch machine will hit itself and the medicine will cause the stone fire to spontaneously combustion, and the wind and rain will not be wet, and the emergency can be handy."

"The student has seen the self-generated fire gun mentioned by the chief soldier in the "Illustrated Description of Weapons", but I don't know if it is the same thing?"

The self-fired firebolt is also known by a more well-known name, the flintlock pistol.

Compared to the arquebus, the flintlock pistol is undoubtedly a huge step forward.

Because the arquebus needs to use the characteristics of arquebus ignition, the shooter must maintain a large interval when firing, so the density of frontal fire is not large, and it cannot effectively contain the enemy's charge.

The flintlock pistol, on the other hand, had no such concerns, and the flintlock musketeer could stand close together like a normal infantryman, and the frontal fire was more than twice as powerful as the arquebus.

And because it is not necessary to light the fire with a fire rope, but to clamp a piece of flint with the jaws of a hammer, and a blow anvil is provided on the side of the fire transfer hole.

When firing, the trigger is pulled, and under the action of the spring, the flint is hit heavily on the edge of the fire door, and sparks are emitted, which ignites the gunpowder and fires. The firing process was greatly simplified.

As a result, the rate of fire is faster than that of the arquebus, and soldiers can become proficient with flintlock pistols more quickly.

Field artillery can only provide advantages on the battlefield, but flintlock pistols can change the situation of the entire battlefield, and even lead to the innovation of warfare.

The popularization of flintlock pistols and the installation of bayonets made it possible to line up and shoot in later eras, eliminating all tactics and becoming the main theme on the battlefield.

Chen Wang was a little surprised, Bo Yu not only remembered that the self-generated fire gun was from the "Illustrated Description of Weapons", but also said the original words recorded word for word.

"Yes, it is the self-generated fire gun recorded in Bi Maokang's "Illustrated Description of Weapons"."

Chen Wang's memory has strengthened a lot now, and he almost has the ability to remember, but Bo Yu should not have it.

Sure enough, in this era, there are few mediocre people in the imperial examination, even if they are showmen, and this memory is amazing.

"I have a few self-generated firecrackers here that can be used as a reference, I don't know if Mr. Bo has made a new firecracker based on these self-generated firearms."

"This is not difficult, this is not difficult......"

Bo Yu's eyes lit up, as if he had seen some rare treasure, and he said at the moment.

"It's not that students boast about it, waiting for idle weapons, students only need to look at the structure, and they can imitate it."

Bo Yu himself is extremely fascinated by firearms and ordnance.

When it comes to other things, he can be indifferent, but when it comes to ordnance skills, it is difficult for Bo Yu to calm down.

In "Illustrated Weapons of Weapons", Bo Yu has seen a lot of new firearms, but because of his identity, it is difficult for him to get in touch with the items in them.

He wanted to buy a self-made firecracker, but it was a big sin to keep it private, and he couldn't find a place to sell it in Wumen, Suzhou and other places.

Now hearing the few self-generated firearms that Chen Wang actually brought, Bo Yu was naturally excited in his heart.
