In a simple laboratory, carefully mix the three substances according to the scientific ratio, and stir the mixture repeatedly in a pottery bowl.

It is very dangerous to make gunpowder. In order to prevent static electricity from clothes, Wang Lang went into battle with his shirtlessness.

After stirring these things thoroughly into powder, the dark substances in the pottery bowl looked no different from the gunpowder I had in my impression.

But he knew that this powdery gunpowder was not very powerful.

If he wants to increase the power of gunpowder, he is guaranteed to burn fully. In his impression, the black gunpowder in the Firearm Age was all granulated gunpowder of similar sizes, and he had no clue as to smokeless gunpowder.

If you want to pellet the gunpowder, you must first make it into mud.

Wang Lang once heard of a way to make granular gunpowder, which is to stir with egg whites, but this method is obviously unrealistic. For this reason, Wang Lang thought for a long time and decided to stir the powder with clean water and wine.

The powders were stirred into a paste, and sieved them into granular shapes with twine. Three days later, the dried granular gunpowder appeared in front of Wang Lang.

Carefully put these gunpowder into the characteristic clay pot, insert a dry weed, ignite it, and quickly run aside to hide.

As the weeds slowly burned out, a loud bang made a loud bang, and the clay pot had been blown up in pieces, and some fragments were even stuck directly on the brick wall.

The sudden loud noise made the residents of Yancheng tremble. The guards guarding here were already scared to death and they all lay on the ground and prayed to the heaven, hoping that the gods would not let down their anger.

Wang Lang was very satisfied with the effect of this explosion. The power of this black gunpowder was already strong enough. With modern knowledge, the Xia Kingdom could directly transition from the cold weapon era to the gunpowder era.

After the success of the experiment, Wang Lang immediately called Mu Feng and asked him to select new subordinates to enter this secret place. He also asked these people to strictly keep the secret here. Except for the relevant personnel, no word must be disclosed to anyone.

After four months of research, the Ministry of Works has successfully copied the crossbow, and the iron parts on it can only be replaced by bronze.

The craftsmen pushed the huge crossbow out of the city, and Wang Lang personally attended to watch the effect of this crossbow.

The craftsman installed three thick crossbow arrows in the huge arrow bag of the crossbow. As he pulled the trigger, the thick crossbow arrows roared out, and suddenly pierced through the wooden board a hundred meters away, and flew out more than ten meters before he pierced into the soil.

The crossbow arrow quickly pulled into a full moon shape again, and the second crossbow arrow flew out again. The time before and after the two arrows was no more than twenty seconds. This efficiency is many times better than the previous ones that were fired one minute at a time.

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

Upon hearing this, Mu Feng hurriedly asked someone to hand over a small crossbow arrow to Wang Lang.

Wang Lang looked at it himself, raised the crossbow arrow and pointed it at the front and kept pulling the trigger.

"Swish!"

All five crossbow arrows in the arrow sac were fired in less than half a minute, and the shooting accuracy was many times more accurate than the longbow, but their power was still not as powerful as the longbow. This kind of crossbow arrow can break armor within fifty steps, and it has no effect after more than fifty steps. It can be said that there are both advantages and disadvantages.

Giving the crossbow arrow to the person beside him, Wang Lang said: "These two weapons need to be produced on a large scale and they must be equipped to the army within one year. Can your Ministry of Works do it?"

"Don't worry, your Majesty, we are already very familiar with the method of making crossbow arrows. We can make a thousand aircraft in less than a year or half a year." Mu Feng said confidently.

Wang Lang looked at Mu Feng in surprise. In half a year, one thousand aircraft could produce ten crossbow arrows in an average of one day. Even the most skilled craftsmen could not achieve this efficiency. He couldn't help but wonder if Mu Feng was talking big.

"It took half a year to make it. So many, are there many skilled carpenters in your Ministry of Works recently?" Wang Lang asked with his eyes narrowed.

Mu Feng smiled and said, "Your Majesty doesn't know that we don't need everyone to be proficient in the production of crossbow arrows. We use measurement tools to specify the size of each component, as long as everyone is familiar with the parts they make. This will greatly reduce the difficulty of making. After the parts are completed, it will be enough to assemble them. Moreover, there is still a lot of wood in our country that has been drying for more than a year, and there is absolutely no problem in half a year."

After hearing what Mu Feng said, Wang Lang also recalled that he had told Mu Feng that this standardized production model was the one he told, and he couldn't help but laugh and said: "It's great, just follow this method. After completion, everyone in the Ministry of Works will reward 100 yuan."

When the Ministry of Works heard this, everyone was delighted and hurriedly thanked Wang Lang.

After the weapon demonstration was completed, Wang Langyou asked about the production of Mufeng paper.

Mu Feng sighed and said, "Your Majesty, although we have your guidance and make the paper you mentioned by boiling weeds and bark, there has not been much progress so far. The things we make cannot be used at all and will break with a slight touch."

Wang Lang nodded. He understood that this kind of thing was not achieved overnight. It had to go through many failures to achieve success. He said slowly: "You don't need to be too impatient about this matter. Study it slowly, and sooner or later there will be progress."

Mu Feng nodded when he heard this.

After demonstrating the weapon, Wang Lang and everyone returned to the city. When passing by the Daxia Academy, they heard the literacy sounds coming from inside and couldn't help but stop.

Let the people from the Ministry of Works leave on their own, Wang Lang slowly walked towards the academy with a few guards.

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

Wang Lang signaled them not to speak out, and took a lighter pace. He came to the school palace and stood beside him and watched the spacious courtyard. Rows of children followed the teachers sent by the Ministry of Rites to learn to read.

And his three-year-old child Wang He also chanted these words as if shaking his head.

These teachers are the children who learned knowledge from Wuyun. After so many years, these older children should grow up and become officials of the Ministry of Rites.

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

"Follow me to read, Zhao Qian, Sun Li!"

After the teacher finished speaking, the little-faced child shook his head and said, "Zhao Qian, Sun Li!"

"Zhou Wu and Zheng King, Feng Chen and Chu Wei."

...

After the children read it one by one, the young teacher said, "These twelve words include most of the surnames in our Xia Kingdom. You can find your own surnames from them. Today, we will learn these twelve words and teach you to write your own name tomorrow."

The students read the twelve words several times, and then the teacher called out a little boy and said, "You read it again."

The little boy was nervous and trembling, and he said tremblingly: "Zhao...Zhao Qiansun Li, Zhou Wu Zheng Wang, Wang... Wang...what...wei."

The child who had not read all the words was immediately called over. The young teacher took out a wooden stick and hit him in the palm of his hand. The child was crying with pain. The miserable cry scared the rest of the children.
