And Zhao Gang's 100 households have also been incorporated into the Department of Inspection and Strategy, Wang Wenle is of course happy, but Jinyiwei's military salary is higher than the current level of recruits, so it is not suitable for mixed formation, and because Zhao Gang is a veteran of a hundred battles, so as long as a little training can become an elite soldier, so he arranged for everyone to still train together, so as not to delay the predetermined goal.

When Wang Wenle was stepping up the training of his subordinates, the emperor secretly ordered Wang Wenle to return to Beijing quickly, and the emperor's order could not be violated, so Wang Wenle simply cleaned up, and rushed back to Beijing with a small flag guard, and Wang Zhong brought him to the place to know that the original artillery was made before the arquebus, this is because Wang Wenle was negligent in the process of making guns, although the cannon is small, but the smaller it is constrained by the level of craftsmanship at that time, the more difficult it is to make, and the bronze casting process of making cannons has long been mature, What is lacking is mainly ideas, and the ideas given by Wang Wenle just solved the most difficult part for the craftsmen at that time, one is the best proportion of gunpowder, the other is the proportion of the caliber of the gun and the length of the gun, and all the configurations required by the artillery are all described and illustrated, which makes the craftsmen only need to simply think about how to make it better, durable without inventing and repeatedly exploring and experimenting.

In fact, the first cannon was made in three days after the craftsmen got the drawings and instructions, mainly the inheritance of the craftsman spirit, these guys came up with beautiful data on accessories, gunpowder ratio and chamber pressure test, number of shots test, best effective range test, etc., and only tested chamber pressure to blow up more than a dozen artillery test items. After testing, it is believed that the optimal weight of the cannon of the small cannon is two catties, the effective firing range is about 400 steps, and the total weight of the gun carriage is only about 600 catties, and it is very easy for four people to operate. The light cannon craftsmen had a more unique opinion, they believed that the power of the light cannon was not enough to defend or break the city, and it was the best choice for use on ships, because the cannon was too small and the walls were too strong; The battering ram or catapult target is too small and may not be able to destroy it even if it hits, so at least 20 catties of cannon weighing more than 20 catties are needed, and the cannon weighs about 5,000 catties. Now they are all wooden sailing ships, so ten pounds of guns can be indestructible to all hulls, so the craftsmen suggested that only small cannons were enough for field battles, and they were light in weight, and there were gun carts that could be easily towed away by mules and horses. Then, based on the data given by Wang Wenle, these guys came to the conclusion that after repeated tests, they created a light cannon weighing eight catties, an effective firing range of about 600 paces, and a cannon weighing about 2,000 catties.

After the experimental results were sent to Zhu Di, Zhu Di was overjoyed, and he quickly summoned Wang Wenle to Beijing to test the gun.

Wang Wen was optimistic after seeing the test cannon, this is not just want to fall asleep someone sent a pillow, so he pointed out that the siege gun is not an artillery that needs to be studied urgently, the main research is the effective range of about 1,000 steps of small and medium-sized cannons, although the effective range is far away and can not see the useless, but the increase in the effective range is actually a multiplication of the destructive power at close range, so the small cannon is mainly in the gunpowder purification and the smoothness of the breech, the higher the purity of the gunpowder, the more fully burned, The greater the propulsion of gunpowder, the smoother the inside of the chamber, the less resistance the cannon will shoot, which is the research direction of the second generation of small cannons; In addition to improving the light cannon like a small cannon, the cannon was increased to ten catties, and the weight of the cannon was increased to three thousand catties, and the cannon used on the ship could be heavier according to the current ship standards. This is where the second generation of light cannons is being studied. He won't let the craftsmen study the siege artillery, the most important thing is to consider Zhu Didi's feelings, what do you want to do with siege artillery when you go to sea to make money? One is that Zhu Di will not give, the other is a waste of time and resources, Daming is not a copper-rich country, and even the raw materials for making copper coins are nervous, not to mention that this siege cannon will cost tens of thousands of catties, it is better to use good copper on the blade, focusing on the development of naval artillery, so that Zhu Di can sleep well every day, and he can go overseas with peace of mind to toss casually, why not do it?

The craftsmen said that the three-thousand-pound cannon body needs various experiments in casting, so it takes time, Wang Wenle of course knows that in the case of ideas, every step needs to be verified by experiments, which is urgent, as long as the general direction is right, the rest is to give the craftsmen time to toss repeatedly.

Finally, on the issue of gunpowder of artillery, on the battlefield due to tension, mistakes and other reasons caused by insufficient or excessive charge, resulting in insufficient range or explosion, self-harm, self-martyrdom and other situations that delay the fighter, so the gunpowder is loaded in advance in flammable packaging and pressed tightly, so that it not only saves the time of charging on the battlefield and pounding the powder, but also can prevent low-level errors that may occur when charging, leaving no residue. Seeing that all the craftsmen were meditating, he gave an example of oiled paper, which is waterproof and moisture-proof, and is more flammable, so it can be used first, and then replaced with better materials.

As he was leaving, the craftsmen present knelt on the ground, and said that he was confused by the guidance of the Holy Immortal Master of Firearms, and he was confused, what he just said seemed to be related to artillery technology, and he didn't say anything related to feudal superstition......

Then Wang Wenle went to see the production of the arquebus, which was no problem for the cast iron process of the Ming Dynasty, because the arquebus was originally cast iron integrally, but because the caliber of the arquebus was too small, the barrel was too long, and the process of smoothness of the inner chamber was not ideal, so the progress stalled. Wang Wenle told the craftsman who made the gun that he could solve the technical problem of the smoothness of the bore alone, and at the same time make other parts of the gun first, regardless of whether the barrel process was rough or not, and first test whether other functions were suitable and find problems and improve them in time, so that a lot of time could be saved.

Finally, there is the question of fixed gunpowder, the difference with artillery is that the inner part of the ammunition package is made into three parts, the bottom layer is compacted gunpowder, the middle layer is the projectile, and the top layer is some bulk gunpowder, and then wrapped in flammable fire oil, and the rope is used to tie the knot. When loading, hold the gun in one hand and the ammunition bag in the other hand to the mouth and use your teeth to pull the slipknot of the tie rope, then pour the top layer of bulk gunpowder into the powder pool, and then stuff the ammunition bag into the muzzle and poke it to the bottom with a whole strip. How much time can be saved? No matter how good it is, it is better to actually test it, make ten gunpowder packs, find two test guns, one according to the traditional method, one according to the new method, subject to the completion of ten gunpowder packs, after the results came out, a group of craftsmen and craftsmen were stunned that it was actually ten to four, and then the craftsmen fried the pot, if this is a familiar hand, wouldn't it be able to play ten to three, and it would not be wrong. The craftsmen present instantly knelt on the ground, and also thanked the firearm saint immortal master for pointing out the maze, just confused now of course understand, the arquebus will have to wait for fifty years later, the fixed gunpowder he just said is the musket after two hundred years of development history before it appeared, it is not an exaggeration to call him a firearms master, grandmaster, the immortal master is a little too much, the saint immortal master is... Hee-hee...... I'm sorry......

Then Wang Wenle was taken by Wang Zhong to Zhu Di's imperial study, saluted, gave a seat, and gave tea, Wang Wenle told Zhu Di the results after the test, and said that this was greatly beyond the expectations of Taizu and his old man. However, since Taizu and his old man can know the situation of future generations, he has naturally told Wang Wenle in advance how to improve this artillery, and said that Taizu Youxun does not need to build siege artillery at present, one is the reason for the loss of labor and money, and the other is that the siege artillery appeared in advance and is harmful to my Ming Dynasty. Of course, Zhu Di understood what Taizu meant, and nodded again and again with great satisfaction. Regarding the manufacture of arquebuses, Wang Wenle said that the speed was much faster than Taizu and his old man expected, but now the craftsmen are thinking of how to improve the process to increase the output, so please Zhu Di Don't worry, it is expected to be a few months of effort, because the experiment alone requires dozens or hundreds, if the problem of the process is not solved, there is no use without output.

These craftsmen are the priceless treasures of my Ming Dynasty, Taizu he repeatedly emphasized that they must be treated well, with these craftsmen and their skills passed on from generation to generation, gradually improved, continue to lead, I can truly govern the internal and external security, the national fortune is lasting and prosperous.

Zhu Di solemnly expressed his understanding and support, and ordered Wang Zhong to later issue a decree to reward the craftsmen who made the guns, and to give an order to the craftsmen who made the guns; and double the treatment of firearms craftsmen and exempt them from all servitude. Wang Wenle hopes to change the treatment of craftsmen, and finally began to make substantial progress.

Then Zhu Di told Wang Wenle about the actual functions of the Department of Auditing and Strategy, he told Wang Wenle to remember not to act rashly before he was full-fledged, he didn't want to cause turmoil in the court because of this matter, and cause some unexpected troubles, and the major thing that interfered with Taizu was that he was unfilial as a son, remember to lie dormant, and then he asked Wang Wenle about the military rank.

Wang Wenle praised Zhu Di first, of course, in the name of Taizu and his old man, saying that the Department of Auditing and Scripture and the Department of Colonial Education have the same effect, but Zhu Di used the name of anti-smuggling to hide and confuse the ministers, appreciating that Zhu Di is not confined to tradition, is a pioneering king, and is stronger than Taizu and his old man, he really regretted passing on the throne to Yunwen back then, otherwise there was no Jingjing in those years, the Ming Dynasty would have been stronger, and the people would not have to suffer from this catastrophe.

Although Zhu Di is nearly sixty years old, when he heard his father say this, he also burst into tears, and he almost wanted to cry.
