[Today's first update!] 】

Liu Minghua looked at the surprised Cheng Biting Jin and Niu Jinda, and said with a serious face: "I'm talking about the core personnel in charge of the formula!" These personnel must be in and out! If they want to go out to play, we also have an organization, and they are not allowed to contact any outsiders alone! ”

Cheng Yanjin and Niu Jinda thought for a while and nodded: "These core personnel really can't contact the outside world, and it's reasonable to do so." What about the others? ”

Liu Minghua said: "Other people can relax a little, but they are still not allowed to contact with any outsiders!" I know it seems a bit cruel to restrict their freedom in this way. But for the sake of Datang's safety, we must do this! ”

"Okay, you can say whatever you want!" The gunpowder was led by Liu Minghua, and Cheng Biting Jin and Niu Jinda must do it according to Liu Minghua's requirements.

Niu Jinda hesitated and said: "Minghua, if you want to find someone who can be trusted, some wounded soldiers in the army can be trusted, but their bodies are ......."

Liu Minghua thought for a while and said: "Disabled veterans, as long as they are reliable, there is no problem in entering the gunpowder factory!" It doesn't take a lot of body to assemble gunpowder, and if these disabled veterans come in, they are just in charge of commanding! ”

Cheng Yanjin said: "Who are the people who are working?" ”

Liu Minghua hesitated and said, "The people who do the work ...... Hey, if only there were a large number of death row inmates! It is not bad to behead them without beheading, and let them undergo labor reform here for the rest of their lives. ”

Niu Jinda shook his head and said: "Death row prisoners, this is very few, and it is not realistic to rely on these people." ”

Liu Minghua nodded. History records that there were really few death row prisoners during the Tang Dynasty. Sometimes. There are only a few hundred death row inmates in the country in the whole year. It seems that relying on death row prisoners is not very realistic.

Niu Jinda said again: "Minghua." Although there are few prisoners on death row, it is not difficult to find some slaves. How much you want! By the way, there were many slaves who could not read, could not write, and had their tongues cut out and could not speak...... I think it's okay for such a person, right? ”

Liu Minghua was shocked: "What? Are there all such slaves? If there is, that's great! In that case, the personnel problem is solved! Uncle Niu was responsible for the supervision of the entire gunpowder and was responsible for the secret recipe; Several personnel are responsible for the core part; A group of slaves is in charge of assembling gunpowder! ”

Niu Jinda nodded and said, "Okay!" Such a clear division of labor is very good! ”

Liu Minghua smiled. continued: "The production link is clear! Then, the gunpowder produced was stored and handed over to Uncle Cheng to take care of. ”

Cheng Yanjin said strangely: "Let's take care of gunpowder?" Why isn't Uncle Niu taking care of it? Wouldn't it be more convenient for them to produce and take care of it? ”

Liu Minghua shook his head and said: "The production of gunpowder and the storage of gunpowder must be divided into two parts!" Gunpowder production sites and storage warehouses must be separated by great distances. In the event of an explosion at the gunpowder factory, it will not affect the gunpowder warehouse. We must pay attention to this security issue! ”

Cheng Biting Jin and Niu Jinda suddenly realized: "I see! ”

Niu Jinda said: "Minghua, you are really thoughtful! And it has a great sense of strategizing. After you say so. Then we should be able to produce the first batch of gunpowder in three days! ”

Liu Minghua said: "The venue and personnel seem to be fine. What about the materials used to make gunpowder? ”

Niu Jinda smiled: "There is naturally no problem with this. Vanishing, sulfur, charcoal...... How much you want! It's just that Majesty said that there was some material in it that he couldn't understand? This requires you to make zuò yourself! In short, all the materials are not a problem. ”

Liu Minghua said: "That's good! That's right, the incomprehensible material. It's actually made of ordinary materials too! In short, I will take out the details of the method of making gunpowder zuò and hand it over to the royal family! Hehe. I don't dare to have such a powerful weapon in my hands! If that's the case, I'm afraid your majesty won't be able to sleep well. I can't sleep well, do I? ”

Cheng Yanjin laughed and didn't say anything.

Niu Jinda gave Liu Minghua a thumbs up and said, "Minghua, you are young. It's really rare to know how to advance and retreat so well! By the way, let me ask you - could it be that your mysterious gunpowder recipe came from heaven? ”

Liu Minghua said seriously: "That's nature!" Otherwise, where would I know such a magic formula? However, God gave this formula, mainly to speed up the construction of Datang! Therefore, it cannot be used on a large scale in military affairs now, otherwise, it will be acting against the sky! ”

"Providence cannot be violated!" Cheng Yanjin and Niu Jinda shook their heads and sighed.

Liu Minghua looked up at Tiandao: "Three days, time is pressing, we are going to start now, right?" ”

Cheng Yanjin said with a smile: "Let's go, let's go out of the city immediately and go to see the production site!" ”

Next, Liu Minghua, Cheng Yanjin, and Niu Jinda immediately left Chang'an City and arrived at a relatively secret military camp.

Cheng Yanjin smiled: "Minghua, what do you think of here?" ”

Liu Minghua looked at the overall terrain and said, "Not bad!" Can't imagine that there is such a terrain outside Chang'an City? It's just that this place seems to lack water? Any factory is inseparable from water! If there was a stream that could flow through here, it would be great! ”

Niu Jinda said: "Minghua, you are really like a torch!" There was water from a mountain spring not far away, and we had conceived a ditch to bring it directly to the barracks. However, the boulders on the mountain are too hard and require a lot of manpower to excavate, so this idea can only be postponed. ”

Liu Minghua followed Niu Jinda's hand, looked at the mountain spring not far away, and then said with a smile: "This method is good!" After our gunpowder production is successful, we will first dig a ditch with gunpowder and introduce the mountain spring water into the barracks! However, the place of the mountain spring needs to be guarded. ”

Cheng Biting Jin said: "On that peak, there were already guards. However, if the mountain spring water is introduced into the barracks, the number of guards on the mountain peak will be multiplied! ”

Liu Minghua shook his head and said, "Multiplication? That's not enough! That mountain peak is the highest vantage point in this area, so it must be guarded and guarded by many people. ”

Niu Jinda said: "Okay! People are not a problem! It's too important there! Otherwise, if someone poisons the mountain spring, then our entire military camp will be finished! ”

Liu Minghua nodded in agreement with Niu Jinda's statement.

Cheng Yanjin said again at this time: "Minghua, look at this terrain again, which ones need to be strengthened defense?" ”

Liu Minghua pointed to the military camp in front of him and said: "This military camp is surrounded by mountains on three sides, there is only one exit, and there is a huge open space in the middle. If the two armies clash, the terrain of this basin will be a dead end! ”

Niu Jinda smiled: "Minghua seems to know the terrain very well!" Yes, this terrain is near Chang'an City, and it is basically not surrounded by strong enemies on all sides! ”

Liu Ming said cautiously: "Don't you dare to be so careless!" You know, this gunpowder factory is too important! The possibility of the enemy being surrounded from all sides is not ruled out! Therefore, in order to put an end to this possibility, we must designate a five-mile radius of this place as a military exclusion zone! Miscellaneous people are not allowed! ”

Cheng Yanjin was surprised: "What? Five miles away? This...... It's a big place! Besides, there are still many villagers in this area, so how to deal with it? ”

Liu Minghua said firmly: "These residents, all of them have to move out!" A radius of five miles is just the first phase of our plan! In the future, it may be a larger area! By the way, two uncles, you know what a military restricted area is, right? Even if anyone comes in and doesn't heed the warning, they will be killed! ”

"Kill?" Cheng Yanjin gasped and said, "What? For the sake of a gunpowder, to make such a big move? However, we are so excited that we are afraid that we will be impeached by the imperial history, right? ”

Niu Jinda snorted coldly at this time: "What are you afraid of the impeachment of Yushi? What else can those civil officials do all day long except to show off their pens and play tricks? Which part of the Tang Dynasty didn't rely on the blood of our generals? I think Minghua is right! Gunpowder is so important that it is completely necessary to designate a radius of five miles as a military forbidden zone! ”

Cheng Yanjin smiled bitterly: "It can be." However, it is necessary to put all these places surrounded by mountains on three sides and exit within a five-mile radius of each other? It's very difficult! How many sergeants are needed for this? ”

Liu Minghua sighed: "The number of people is naturally indispensable! This gunpowder is so important that there must be at least three lines of defense outside the gunpowder production plant and the storage warehouse! The first line of defense is the outermost line of defense within a radius of five miles; The second line of defense is the top of the hill surrounded by mountains on three sides and the exit on one side; The third line of defense, which is outside the gunpowder production plant and the storage warehouse, is the last line of defense! ”

Niu Jinda waved his hand and said, "Basically, no one can break through these three lines of defense!" ”

Liu Minghua smiled: "Even if there is, every checkpoint where we produce gunpowder and store gunpowder is guarded!" Well, even if there is a magical person who breaks through this layer of levels, then this person will at most wreak havoc in it, and he will never be able to steal the gunpowder formula! ”

Cheng Yanjin and Niu Jinda nodded in unison and said, "Okay!" In this way, it is foolproof! ”

As they spoke, they walked into the barracks.

Cheng Biting Jin said: "Minghua, the terrain is okay, right?" The military house, do you see if there is a problem? ”

Liu Minghua looked at the buildings inside, and then said: "These are all civil structure houses, which can basically be improvised." However, these houses are a bit small, and in the future we will build a larger, more spacious factory to assemble gunpowder!

This place is strictly forbidden to fireworks! There are some factors that can cause fires. At the same time, the new plant also needs to take into account air circulation, food and housing for workers, etc. These will need to be refined slowly in the future. ”

Cheng Yanjin said strangely: "Minghua, large plant, safety, air circulation...... I can understand all of this. However, to care about the food and shelter of those mute slaves who can't speak? This...... Is it necessary? ”
