In the simple laboratory, the three substances were carefully mixed according to the scientific ratio, and the mixture, which was about half a catty, was put in a pottery bowl and stirred repeatedly.

It is very dangerous to make gunpowder, and in order to prevent static electricity on his clothes, Wang Lang went into battle shirtless.

After these things were thoroughly stirred and crushed into powder, the black substance in the pottery bowl looked no different from the gunpowder in my impression.

But this powdered gunpowder, he knew, was not very powerful.

If he wanted to increase the power of gunpowder, he was guaranteed that the gunpowder could be fully burned, and he had the impression that the black powder in the firearms era was granulated gunpowder of similar size, and he had no clue about smokeless gunpowder.

If you want to granulate gunpowder, you have to make it into a puree.

Wang Lang once heard of a way to make granular gunpowder, which was to use egg whites to stir, but this method was obviously unrealistic, so Wang Lang thought about it for a long time and decided to use water and wine to stir these powders.

The powder was stirred into a puree, and a sieve made of twine was used to sift it into granules, and three days later, the sun-dried granule gunpowder appeared in front of Wang Lang.

The gunpowder was carefully placed in a special clay pot, a dried weed was inserted, and after lighting it, he quickly ran to the side and hid.

As the weeds slowly burn out, "Boom! There was a loud bang, and the clay pot had been blown apart, and some of the fragments were even stuck directly on the brick wall.

The sudden loud noise frightened the residents of Yancheng, and the guards guarding here were already frightened, and they all lay on the ground and prayed to the heavens, hoping that the gods would not lower their anger.

And Wang Lang looked at the effect of this explosion and felt very satisfied, the power of this black powder was strong enough, and with modern knowledge, it could allow Xia Guo to directly transition from the era of cold weapons to the age of gunpowder.

After the success of the experiment, Wang Lang immediately summoned Mu Feng and asked him to select new subordinates to enter this secret location, and asked these people to strictly keep the secrets here, and not to disclose half a word to anyone except relevant personnel.

And the Ministry of Industry, after four months of research, the imitation of the repeater has been successful, and the iron parts on it can only be replaced with bronze.

The craftsmen pushed the huge bed crossbow out of the city, and Wang Lang was there to see the effect of the repeater.

The craftsman loaded three thick crossbow arrows into the huge quiver of the repeater, and with the pull of the trigger, the thick crossbow arrows whistled out, piercing the plank a hundred meters away, and flew out more than ten meters before piercing into the dirt.

The crossbow bolt was quickly pulled into a full moon shape again, and the second crossbow bolt flew out again, and the time before and after the two arrows did not exceed twenty seconds, which was many times more advanced than the previous one-minute bed crossbow.

Wang Lang was very satisfied with the effect of this weapon, and said, "Show me a miniature version of this crossbow arrow." ”

When Mu Feng heard this, he hurriedly asked someone to hand over a small crossbow arrow to Wang Lang.

Wang Lang looked at it himself, raised the crossbow arrow and aimed it in front of him, and kept pulling the trigger.

"Whoosh!"

The five crossbow arrows in the quiver were all fired in less than half a minute, and the shooting accuracy was many times more accurate than the longbow, but it was still inferior to the longbow in terms of power, and this kind of crossbow arrow could break the armor within fifty steps, and it was completely ineffective if it exceeded fifty steps, which can be said to have advantages and disadvantages.

Handing the crossbow arrows to the person beside him, Wang Lang said: "These two weapons will be mass-produced and equipped with the army within a year." Can you do it? ”

"Your Majesty, rest assured, we are already very familiar with the production method of this crossbow arrow, and we will be able to make a thousand in less than a year or half a year." Mu Feng said confidently.

Wang Lang looked at Mu Feng in surprise, a thousand crossbows in half a year, this average can produce ten crossbow arrows a day, this efficiency is not even the most skilled craftsman, he can't help but wonder if Mu Feng is talking big.

"It took half a year to make, so many, do you have a lot of skilled carpenters in your Ministry of Industry recently?" Wang Lang squinted his eyes and asked.

Mu Feng said with a smile: "Your Majesty doesn't know, we don't need everyone to be proficient in the production of this crossbow arrow, we use measuring tools to specify the size of each part, as long as everyone is familiar with the part they make, so that the difficulty of making can be greatly reduced, after the parts are completed, as long as they are assembled, and there are still many woods in our country that have been dried for more than a year, and there is absolutely no problem in half a year." ”

After listening to what Mu Feng said, Wang Lang also recalled that this standardized production model was still told to Mu Feng by himself, and he couldn't help but laugh dumbly: "Very good, just do it according to this method, and after it is completed, everyone in the Ministry of Industry will be rewarded with 100 yuan." ”

Everyone in the Ministry of Industry was overjoyed when they heard this, and hurriedly thanked Wang Lang.

After the weapon demonstration, Wang Langyou inquired about the production of wood-style paper.

Mu Feng sighed and said, "Your Majesty, although we have your guidance to make the kind of paper you said by boiling weeds and bark, there has not been much progress so far, and the things we make are simply unusable, and they will shatter at the slightest touch. ”

Wang Lang nodded, he understood that this kind of thing was not achieved overnight, and it had to go through many failures to succeed, and said slowly: "Don't be too anxious about this matter, study it slowly, and there will be progress sooner or later." ”

Mu Feng nodded when he heard this.

After demonstrating the weapon, Wang Lang returned to the city with everyone, and when he passed by the Great Xia Palace, he heard the sound of literacy coming from inside, and couldn't help but stop.

Let the people from the Ministry of Industry leave on their own, and Wang Lang slowly walked towards the school palace with a few guards.

When the soldiers guarding the school palace saw Wang Lang coming, they hurriedly bowed to greet him.

Wang Lang signaled them to be silent, slowed down, and came to the school palace to stand aside and look at the spacious courtyard, rows of children cognitively following the teachers sent by the Ministry of Rites to learn literacy.

And his three-year-old child, Wang He, also shook his head and recited these words.

These teachers are the children who followed the dark clouds to learn knowledge at the beginning, and after many years, these older children should grow up and become officials of the Ministry of Rites.

The young teacher, with chalk made of lime powder, wrote on the blackboard Zhao Qian, Sun Li, Zhou Wu, Zheng Wang, Feng Chen Chuwei, twelve big characters.

"Follow me, Zhao Qian, Sun Li!"

After the teacher finished speaking, the child in the small face shook his head and said, "Zhao Qian, Sun Li!" ”

"Zhou Wu Zheng Wang, Feng Chen Chuwei."

。。。

After the children finished reading one by one, the young teacher said: "These twelve characters include most of the surnames of our Xia Kingdom, you can find your own surnames from them, learn these twelve characters today, and teach you to write your own names tomorrow." ”

The students read the twelve words a few more times, and then the teacher called out to a little boy and said, "Read it again." ”

The little boy trembled nervously, and said tremblingly: "Zhao. . . Zhao Qian, Sun Li, Zhou Wu, Zheng Wang, Wang... King.. What the.. Protect. ”

The young teacher took out a wooden stick and hit him on the palm of his hand, and the child immediately cried in pain, and the miserable cry frightened the rest of the children to tremble.
