[Today's first update!] Hey, I sent it twice to be reviewed, and I don't know where the violation is, so I have to overhaul it. 】

After Liu Minghua saw that the nitrate was done, he went to make wood-charcoal and sulfur-sulfur.

In short, all materials must be crushed and refined.

By the afternoon, all the raw materials for gunpowder had been completed, and Liu Minghua organized the core personnel to begin to use these materials to configure gunpowder.

This ratio is only known to Liu Minghua and Niu Jinda, so those nuclear figures are just doing a qiē thing according to Liu Minghua's command.

Since the stones are to be fried, the amount cannot be too small, and Liu Minghua has configured hundreds of catties of gunpowder.

Next, Liu Minghua is going to engage in a lead-fire-cable.

The fuse-wire manufacturing is actually very simple. It is made by wrapping cotton or twine thread with gunpowder and heart thread, and applying a moisture repellent to the surface.

It's just that in this era, there is definitely no moisture repellent, and Liu Minghua can only use oil paper to make zuò umbrellas instead.

After finishing it, Liu Minghua said: "Uncle, did the quarryman do a good job of 'cannon-eye'?" ”

Cheng Yanjin said: "According to your instructions, I have already made a few holes more than one person deep, but it is so deep, for a while, the tools can't keep up." The Warden and the Warden are already being built! ”

During the Wude period, there was a martial arts superintendent. The military-weapon supervisor was originally only in the Kaiyuan period, but I don't know why, the name of the military-weapons supervisor was used in the Zhenguan period.

Liu Minghua said: "It's too shallow, the gunpowder is exploded on the surface of the mountain, and the effect is not obvious!" However, without mechanical drill bits, there is no way to achieve a deep hole explosion at a depth of more than 10 meters. But. The power of the cannon hole below the height of one person is really not good. It seems that we have to find a way to find a device that uses instruments to punch holes! How does leverage work? How does the pulley work? Think about this......"

What Liu Minghua said, Cheng Yanjin and Niu Jinda didn't understand it at all, and the two of them could only nod stupidly there.

"Minghua, in this way, tomorrow you can let Your Majesty see the power of gunpowder?" Niu Jinda is most concerned about this.

Liu Minghua nodded and said, "That's nature!" Well, though, how to dig a blast hole, how to clean a blast hole, how to add a guide-fire cable if you fill gunpowder. How to seal the blast hole with clay. How to detonate safely...... It's a technical job, and it's going to be learned by the people involved this afternoon and night. ”

Cheng Yanjin immediately said: "There is no problem, according to your requirements, I have already found a lot of trustworthy people." "The use of gunpowder is Cheng Yanjin's responsibility.

"Minghua. That...... Can we test the power of this gunpowder in advance? Niu Jinda said. Niu Jinda is still afraid that tomorrow they will be embarrassed. You must know that the explosion-explosion effect that Liu Minghua said is earth-shattering, flying sand and rocks, and deafening! If this effect is not achieved tomorrow. There was not even a forced explosion - explosion at all. That's not fun.

Liu Minghua said: "Try the effect in advance? Of course, there is no problem with this! Let me see how to be real? Hmm, see? There's a dead tree in front of you, and there's a big hole in the middle of it? Let's use this dead tree for realization! ”

"Huh? Tree? Is it gun-powder. Can you blow up this tree? Cheng Biting Jin and Niu Jinda were confused. This big tree is I don't know how many years it is, and it is very thick! Such a big tree, even if dozens of war horses run up and crash together, this big tree may not move at all! Could it be that Liu Minghua can blow up this big tree by relying on gunpowder? Cheng Yanjin and Niu Jinda really couldn't believe it.

Liu Minghua didn't explain, he just put the gunpowder into the hole in the tree, and asked the cannon mud to seal, and the remaining guide-fire-rope was not very long, Liu Minghua used the incense to burn incense and worship the Buddha to ignite the guide-fire-rope and then detonate the gun-medicine.

After lighting the incense, Liu Minghua smiled and asked everyone to step back.

After retreating about 20 meters, Cheng Yanjin and Niu Jinda stopped.

Liu Minghua said with a smile: "Two uncles, if you blow up stones, you have to retreat at least a few hundred meters." Well, we're going to have to go back 100 meters too! Safety first!

Cheng Biting Jin said: "100 meters? Oh, that's what you call seventy steps or so? This...... Do you need it? "One step in the Tang Dynasty is 1.5 meters on the left and right.

Liu Minghua smiled mysteriously and said, "You'll know later." Let's go ahead and stand back! ”

Seeing Liu Minghua insisting like this, Cheng Yanjin and Niu Jinda could only walk more than 100 meters away with Liu Minghua.

The incense burns very slowly, which saves a lot of fuse-cord. You must know that the lead-fuse-cable burns about one centimeter per second, which is very fast. If the stone is to be mined with gunpowder, the workers have to travel a long distance after lighting the fuse. How long does this need to burn? Liu Minghua really can't afford to use such a fuse-clue, so he can only rely on this kind of local method.

"Why hasn't it exploded yet? Mo Fei ...... "Seeing that the time is a bit long, Cheng Biting Jin and Niu Jinda are a little uneasy. It was also the first time they had seen gunpowder in this way, so they couldn't figure out if it would be successful for the first time.

Liu Minghua estimated the time, then covered his ears with his hands and said, "Two uncles, the sound is very loud when the gun-powder explodes-explodes, you better cover your ears!" ”

In the future, when the artillery-soldiers fire artillery, all have soundproof earplugs, otherwise the ears really can't stand it. It can be seen how loud the sound is when the gun-powder explodes-explodes.

Seeing Liu Minghua "cowardly as a mouse" covering his ears, Cheng bit Jin and pouted: "Haha, Minghua, you are too guts!" Look at the old man, I ......"

"Boom!" Cheng Yanjin was halfway through speaking, and a loud noise suddenly remembered, almost scaring Cheng Yanjin into sitting on the ground.

Niu Jinda also shook his body a little so that he didn't lose his balance.

Liu Minghua let go of his hand, shook his head and smiled: "This power is even greater than I imagined!" Well? The two uncles, why are they stunned? ”

"This ......" Cheng Yanjin and Niu Jinda didn't seem to hear Liu Minghua's voice, they just pointed to the big tree in front of them dumbfounded, and they didn't know what to say.

The big tree in front of him was already after the explosion just now. Cut off the waist! This process, Cheng Yanjin and Niu Jinda have seen it with their own eyes! Because the canopy of the big tree stayed for a while before it slowly fell to the ground!

Liu Minghua stepped forward and patted the stupid Cheng Biting Jin and Niu Jinda and said, "Let's go, two uncles, let's go and see the explosion-explosion effect." ”

"Oh, good!" Cheng Biting Jin and Niu Jinda reacted at this time, and then followed behind Liu Minghua a little mechanically. They seem to understand what is happening, and subconsciously they should cheer. But they still don't believe it's real! How is this possible? Such a stout tree, with only a little bit of gunpowder just now, was blown up by the waist?

Walking to a place 30 meters away from the big tree, Liu Minghua pointed to the mess on the ground and said, "Two uncles, if you were standing here just now. It must be disgraced at the moment. Maybe it's bleeding from your mouth and nose, right? ”

Cheng Yanjin and Niu Jinda looked down at the ground and nodded a little scared. At the moment, their brains are still dizzy and their ears are still buzzing. There is no recovery of normal hearing.

Liu Minghua walked to the big tree. Observe it. Then he said, "Well, this big tree has excellent wood." It's a pity that it just died. The two uncles looked at the fracture...... Proves that our gunpowder is okay, right? ”

"Okay? What's okay? It's nothing short of earth-shattering! ”

"This ...... It's really earth-shattering! ”

"This gunpowder, if it explodes in the enemy's formation. That ...... effect."

"Minghua, with this thing, my Datang will definitely dominate the world......"

Cheng Biting Jin and Niu Jinda are now excited.

Liu Minghua smiled bitterly and said, "Wait, two uncles, stop, stop!" Calm down now! What did I say before? This gunpowder can only be used in construction, not in military affairs! Otherwise it will ......"

"Ah, yes, yes, yes, or we will be damned!"

"Minghua, it seems that you are really prescient! I knew that after seeing the effect of this fire-explosive-explosive, some people would want to use it in battle-......"

Cheng Biting Jin and Niu Jinda came to their senses. Then happily discuss the effect of this explosion.

This loud bang really shook the entire barracks. Without biting Jin and Niu Jinda, he gave an order in advance, and everyone in all the barracks was basically calm, and no one was on their backs.

Witnessing the power of this gunpowder, Liu Minghua is also in a good mood now.

Next, Liu Minghua organized relevant personnel to train and learn.

The people of the Niu Jinda organization learn how to produce and dispense gunpowder. The production and configuration process implements an assembly line, each type of work is responsible for different work, and finally the assembly of gunpowder is the core personnel.

For the training of these people, Liu Minghua repeatedly emphasized that quality and safety!

Liu Minghua told everyone that the production of gunpowder is not a year or two, but a hundred years and a thousand years!

Centennial plan, quality first!

Centennial plan, safety first!

This is the slogan put forward by Liu Minghua!

The people of the Cheng Biting Gold Organization are responsible for the storage and use of gunpowder. Of course, Liu Minghua also repeatedly emphasized a safety!

Especially for the storage of gunpowder, Liu Minghua is extremely demanding! You must know that there is a large amount of gunpowder stored in the gunpowder warehouse, and if a safety accident occurs and the gunpowder is exploded, it is needless to say what the consequences are.

Of course, eggs can't be put in one basket. The gunpowder produced was not stored in one warehouse, but was divided into three warehouses. There is a certain safety distance between the three warehouses, and even if one warehouse explodes, it will not affect the safety of the other warehouse.

After talking about the storage of gunpowder, Liu Minghua explained the use of gunpowder.

For the next period of time, gunpowder was mainly used for quarrying stones.

Liu Minghua explained what kind of mountains are suitable for mining stones, what the faults between the stones look like, and if the number and depth of the cannon holes are determined according to the terrain, etc.

In order to facilitate the transportation problem, it must be that blasting and quarrying stones are carried out at the foot of the mountain. In some places, you can go a little higher, and then use ropes to make a ropeway and slide the rocks down the mountain.

However, there was no wire rope in the Tang Dynasty at this time, so how to make a rope that is not easy to break also needs to be studied. Of course, this is not a problem, and this era is not without moisturizing-slippery-oil.

Of course, a lot of knowledge can't be talked about in one night, so Liu Minghua focused on tomorrow's display. The gunpowder is still afraid of moisture, and it is impossible to bury the gunpowder in the cannon eye on the top of the mountain tonight, and wait for Li Shimin to come and explode again tomorrow, so we can only talk about it tomorrow morning.

At night, Liu Minghua lay on the bed, tossing and turning and couldn't sleep.

Gunpowder, which cannot be used in military affairs? This is, of course,!

Liu Minghua knows that he cannot change the general trend of history. Gunpowder, sooner or later, will be used in military affairs! Instead of letting foreigners use fire-gun-cannon to teach us who invented gunpowder a lesson, as the world did in the past, it is better to use gunpowder to conquer these foreign devils and conquer these barbarian lands now!

However, Liu Minghua was afraid that the pace would be too fast, and he was worried that according to the current level of science and technology in Datang, there would be no way to safely and quickly manufacture gunpowder into weapons.

But you can't choke on food! Is it because the scientific and technological level of the Tang Dynasty is not good, so it will not develop fire-medicine-weapons?

Liu Minghua gritted his teeth and decided to develop it secretly!

Coming to this world, Liu Minghua still lacks a sense of security.

Last time, because there were two suns in the sky, Li Shimin almost killed him! Although the catastrophe was successfully resolved later, this incident still sounded the alarm for Liu Minghua - his own safety must be in his own hands! No one can threaten their own safety!

After Liu Minghua understood this truth, he has been thinking about how to establish his own power.

But what is the scale of this force? What is the goal of this force? Will this force get out of control in the future? This is also what Liu Minghua is worried about.

However, despite this uncertainty, Liu Minghua finally determined that this step must go out! Liu Minghua didn't expect to overthrow the Tang Dynasty, and having that idea was purely painful! As long as the royal family is worthy of himself, Liu Minghua will be loyal to Datang!

Of course, even if something goes wrong, Liu Minghua thinks he has the ability to resolve it! As long as Huaxia can be strong, Liu Minghua feels that nothing else matters.

As for the composition of his own forces, Liu Minghua has also been thinking about this issue.

On the economic front, it now seems that Xiaojiao can be relied on. And Xiao Ji's performance during this period of time is also reassuring to Liu Minghua.

In terms of military affairs, Liu Minghua thought about it, and he still had to rely on Su Dingfang.

In the past few days, Su Dingfang sued Liu Minghua and wanted a team of people to protect himself, and Su Dingfang sued Liu Minghua that the wealthy families of Datang are all capable of self-protection. Otherwise, if something happens, the whole family will be doomed.

Su Dingfang told Liu Minghua that the five wounded soldiers who were treated by Liu Minghua's "immortal-medicine" had now recovered, and they really wanted to go to Liu Minghua's side to repay Liu Minghua.

After tossing and turning for a while, Liu Minghua decided to accept Su Dingfang's construction and take those five wounded soldiers as his military-affairs team!

Of course, Liu Minghua has a better gunpowder formula, which is much more powerful than today's gunpowder!

With this, with gunpowder, what are you afraid of?

After making up his mind, Liu Minghua shook his fist fiercely! Then go to sleep! (To be continued......)
