When the medicine bag was about to be blown up, Wang Huan's eyes were sharp, and he had already seen the location of the medicine bag landing in his eyes.

"The medium-sized black powder propellant bag can send a twenty-pound yellow explosive bag out about forty zhang." Wang Huan silently recited in his heart and kept this value in his heart.

Then, he covered his ears tightly.

With a loud bang, a cloud of black smoke suddenly exploded at the place where the medicine bag landed in the distance, rising into the sky in the firelight, churning up, and the loud sound shattered the sky and the earth, shaking like a meteorite falling to the ground, and the entire valley trembled.

Everyone in the military battle bureau who hid behind the stone wall with Wang Huan was an old craftsman who was accustomed to seeing the power of yellow explosives, and they were accustomed to it, and they lowered their heads without changing their faces to avoid the strong wind blowing in their faces.

I saw that at the explosion point forty zhang away, a large crater appeared on the dirt ground, and a few residual smoke rose, marking that the power of the explosion just now was so terrifying, the two wooden two-wheeled carts placed at thirty zhang and fifty zhang were dismantled and scattered by the strong shock wave, and the broken wooden parts flew everywhere, and one wheel was blown up not far in front of the stone wall, half of it was carbonized, and a little flame was burning the remnants of the wooden part.

It is not uncommon for everyone to have an explosive effect on yellow explosives, after all, they have seen too much, but the shooting of thunder in the sky has made them very surprised.

"My lord, the thunder is really sharp, and the twenty-pound medicine bag can be sent out nearly fifty zhang away, terrifying, even if he has thousands of troops, he can also bombard him." Li Huaien was extremely excited, the realistic effect of the artifact he made with his own hands was the same as Wang Huan expected, which made him deeply encouraged, and he clenched his fists and waved them in front of his chest: "If you can rush to make a large number of systems and be familiar with the army, then my Kuizhou army will be invincible!" ”

Other people have spoken out in agreement, seeing is believing, people who saw the thunder shooting were deeply shocked by the heart, the original medicine bag can also be used in this way, the Ming Dynasty's firearms have never had this kind of use, Wang Zongbing skillfully used the trick, whimsical, the iron bullet into the medicine bag, the direct launch into a wooden board isolation projectile, simply subverted the concept of the use of firearms in the past dynasties, and the resulting revolutionary change will open up new thinking in the minds of the craftsmen present.

There are many skilled craftsmen in the War Bureau, and someone immediately suggested: "Manager Li is right, if you can make a large number of thunderstorms, you can line up horizontally in front of you during the battle, and put a row of medicine bags over, and there will be an iron man and copper horse opposite, and you can also burn him into molten iron and shake him into copper ingots!" ”

Someone else said: "What's even better is that the thunder is light and flexible, no different from the tiger squat cannon, it can be operated in a group of four, far less bulky than the red-clothed cannon, and the Buddha Liang machine cannon can't be compared, it's really a sharp weapon." ”

However, there are still people with doubts, shaking their heads and saying: "But although the thunder is good, it is extremely gunpowder-consuming, a cannon is twenty catties fired at a time, the loss is too great, a big war, if the number of thunderbolts is large, the gunpowder required may be a thousand catties, our gunpowder field, I am afraid it will not be supplied." ”

Everyone said a word, gathered around the crater and discussed warmly, they were all happy for the birth of the new weapon, and made suggestions with the idea of making the thunder better and stronger, this scene made Wang Huan extremely relieved, one person has a limited mind, the flame of firewood is high, everyone works together to find a way to make the thunder more perfect.

Moreover, this kind of discussion can also improve the level of craftsmen in the war bureau and lay the foundation for the development of better firearms in the future.

So he smiled and watched everyone talk, and shut up first.

Li Huaien listened carefully, and after everyone said it again, he concluded: "In addition to these, the thunder also has a more fatal weakness, that is, the range is too close, and there is no problem in dealing with the foot soldiers, but the distance of fifty zhang, the cavalry will arrive in a column, and the launch of the thunder will take time, although it is very fast compared to the cannon, but it still can't stop the continuous echelon impact of the cavalry." ”

He turned around and bowed deeply to Wang Huan, and said in a solemn voice: "My lord, the villain will continue to trial production in the past few days, the number of tests, strengthen the cannon barrel, and strive to maximize the projectile distance, and give full play to the power of the thunder." ”

Li Huaien's eyes were red, his eyes were dark, his cheeks were sunken, he hadn't seen him for two days, and there seemed to be a few more wrinkles and furrows on his face, coupled with his white hair and swaying thin body, making him look like a sixty-year-old man, but in fact, he was less than fifty.

Wang Huan sighed secretly, people who are engaged in technology are like this, they would rather not eat or drink than make the things they care about in their hearts perfect, how fortunate it is to have such talents!

He felt that he had given Li Huaien too much pressure, and he couldn't get rid of it, so he tried his best to show his smile more kindly, and said gently: "Manager Li doesn't have to mind, there is no war here, you can try it slowly, but you can't burn your body, and you can't do it quickly." ”

Li Huaien shook his head, stubbornly straightened his waist and said: "The villain is a down-and-out person, but he is trusted by adults, so he can show his ambitions in life and have no regrets!" The ancients said, the soldier is a confidant who dies, and the woman is the one who pleases himself, if the villain can't solve the worries of the adult, he will not be able to eat and sleep at night, and he will make a thunder one day earlier, and the villain will sleep well one day earlier. ”

Wang Huan didn't know what to say, and looked deeply at Li Huaien's white hair fluttering in the wind for a long time before he sighed and said in a dumb voice: "I asked Ma Chongming, from tomorrow onwards, to add some more money to your supply of money, with a few good cooks, buy some nourishing things, and replenish your body." ”

Hearing Wang Huan's promise, Li Huaien's eyes lit up, and he said: "These are not needed, my lord, it is better to hurry up and find more senior gunsmiths for the War Bureau, there is no shortage of anything here, there is a shortage of people, with people, small ones can do better errands." ”

Wang Huan was stunned, and he wanted to say some more words of concern but was blocked in his throat, looking at Li Huaien's straight hair, he smiled bitterly and said: Who said that eunuchs are all evildoers, and there are also good people among eunuchs.

After changing his tone, Wang Huan remembered something again, so he hurriedly brought it up: "By the way, Manager Li, you were walking too fast the day before yesterday, and you have a new idea, I want to put it forward to you to see if it can be realized." ”

When Li Huaien heard this, the light in his eyes brightened, and he had already summed it up, Wang Huan's new idea must be something he had never seen before, just like a bachelor who had not seen a big girl for decades, Li Huaien immediately became energetic, and replied expectantly: "My lord, please speak." ”

Wang Huan ordered Ma Wannian to take a bird from his guard, put the bird with him upward, and said to Li Huaien: "I think, can you use a steel file to file out straight rifling lines on the inside of this bird system?" ”

He knew that the rifling of modern rifled guns was spiral-shaped, which could keep the projectile shot out of the shooting state in rotation until it hit the target stably, but the spiral-shaped rifling was too difficult to achieve for the end of the Ming Dynasty, and it was basically impossible to do without a precision boring machine, and the boring machine was not something he could build, so he retreated to the second best thing and wanted to carve out the rifling instead.

Rifling is certainly not as good as spiral rifling, but it is much better than smoothbore.

Li Huaien's eyes widened, and he asked puzzledly, "Rifling?" What is rifling? ”

Wang Huan touched his head and thought about it before saying: "It's just a yin line that runs through the inside of the body, a gun barrel, and four yin lines are depicted." ”

Li Huaien was a little confused, he looked left and right, and found that many of the masters present in the War Bureau were as dazed as him, so he turned around and said to Wang Huan sincerely: "My lord, the villain has not heard of the matter of carving a yin line in the chamber of the gun, and please make it clear." ”

Wang Huan had no choice but to collect the little knowledge about firearms in his mind, and carefully explained: "The depiction of the yin line in the bird system has several major advantages, one is to avoid the gunpowder residue from remaining in the chamber, to prevent the residue from clogging and causing the explosion of the chamber after accumulation, and to avoid the trouble of carefully scrubbing the chamber after each shot; Second, the rifling in the chamber is engraved and very slender, which can strengthen the strength of the body with the wide male rifling; Thirdly, the rifling is available, which can maintain the stability of the projectile in the barrel, and after firing, it can also fly forward stably and increase the hit rate. ”

After finishing speaking, Wang Huan raised the bird in his hand and pondered: "As for how to depict, it is recommended to use an iron stick the size of the gun barrel, install a blade with extremely high hardness, clamp it with a mold, and rub it back and forth repeatedly to carve out a straight rifling." ”

There was silence all around, no one spoke.

Reading

Everyone, including Li Dingguo, looked at Wang Huan with the eyes of a god.

After a long time, under Wang Huan's embarrassing continuous fake cough, Li Huaien asked deliciously: "My lord, you, you really haven't done anything in the war bureau?" ”

This is a bit reckless, Ma Wannian immediately reacted, the craftsman is a lowly servant, how can it be that Ping Liangbo did it? He opened his mouth and scolded: "Mr. Li is cautious! Uncle is noble, how can he be in the war bureau? ”

Li Huaien woke up like a dream, and hurriedly took two ear scrapers, and said: "Your Excellency forgives your sins, forgive your sins, it is really what your Excellency just said, it is too incisive, if you are not a master who has been immersed in firearms manufacturing for many years, you can't say such profound remarks." ”

Saying that, he knelt down, Wang Huan pulled him up, and said with a smile: "Don't care, Manager Li, the master of this military sect is an immortal sage, and firearms are also involved, so he knows some fur." ”

Li Huaien shook his head and sighed: "If what adults know is fur, villains are ignorant children." ”

He was a little fascinated, looked at Wang Huan and said, "If you can get the guidance of the master of the adult, the villain will die without regrets." ”

Wang Huan's face was a little red, and Li Huaien's eyes were sincere and expectant, which really made him a little embarrassed to tell a lie, so he had to cover it up with words: "How, Manager Li, can you do it?" ”

Li Huaien came back to his senses, "ah" and lowered his head in thought, and then raised his head and replied firmly: "What the adults said, although the villain does not understand much, he needs to go back and write it carefully on the paper and taste it carefully, but the method of carving rifling is simple, and it can be done, as the adult said, with a blade with high hardness in the gun chamber repeatedly carved, you can draw the rifling." ”

Wang Huan was overjoyed and handed the bird to Li Huaien: "Very good! Then I'll hand over this bird to you, and in three days, I'll come here to test the gun! ”
