In the barracks outside Yanzhou, thousands of soldiers packed up, hundreds of carts carried grain, grass, and baggage, as well as some New Year's gifts from Lu Zhan.

After saying a brief goodbye to Lu Zhan, Zhang Yu got into a carriage, and slowly hung down the curtain on the carriage, and the carriage began to slowly drive towards the west.

thought it was the plot of a movie and TV series, and the two sides told each other about parting, but it turned out to be just a simple goodbye. Seeing the carriage slowly leave, Lu Zhan also slowly turned around and said to the outline of the carriage in the distance, "Wait for me, I will be strong enough to resist the wind from all directions!" ”

There is no way for the traditional farming flow to become strong in a short period of time, and science and technology are the primary productive forces. It seems that if you want to develop rapidly, you need to climb the technology tree and use science and technology to hit everything.

But I am not good at science at all, I will only use some chemical reaction equations in the exam, which is theoretically feasible, but in practice, we must take into account the purity and instrumentation.

Hey? But I do know a little about muskets, although I don't know what rifling is, but I still know the principle.

The gunpowder burns briefly and violently in a confined space, and the kinetic energy generated by the explosion of the gunpowder pushes the projectile. In this way, I can let the craftsmen of Yanzhou give it a try, and now the gunpowder is used for fireworks.

"Xiaohan, you secretly find a group of masters who are proficient in gunpowder for me. Then secretly find a group of blacksmith masters. ”

"Lord, you don't want to watch the fireworks show, this fireworks are really good-looking, just buy the fireworks back, why do you want to find a gunpowder master?"

"Secret."

Although Duan Xiaohan didn't know what Lu Zhan wanted to ask him to do with those gunpowder masters and blacksmiths, he still did as Lu Zhan asked.

Dozens of craftsmen gathered in a mountain villa outside the city of Yanzhou, which was originally a gift from the local wealthy families in Yanzhou to curry favor with Lu Zhan.

The secluded mountain villa happened to be used as a test site for new weapons, and a group of people were arranged to be responsible for the vigilance of the mountain villa, so that they could avoid the leakage of their own experimental results later.

"What did you say this Lord Lu was doing when he called us over. I still have a lot of work to do in my shop. ”

"I'll tell you quietly." Seeing that there was no one else around, a craftsman lowered his voice and continued, "The military master who came to me told me that the lord wanted to make something for us. ”

"Something? What is it. ”

A sturdy blacksmith looked at the gunpowder maker and said, "Why don't you just find our blacksmiths to make things, why do you also find those gunpowder makers, do you want us to make new fireworks with these gunpowder makers?"

"It's not that there is no such possibility, maybe the lord just wants to prepare a surprise for his wife, you know."

The blacksmith and the gunpowder master sat on the bench in the courtyard, picked up the tea and pastries prepared on the table, and ate them, and after a while, they saw a young man in dark clothes.

When I saw that the young man was still followed by a group of people, I knew that the person who came was the current lord of Yanzhou.

"The grass people have seen Lord Lu." These craftsmen saluted Lu Zhan.

After Lu Zhan waved his hand and motioned for everyone to get up, "Master Lu, I hope to let you master stay in this villa before the New Year to complete one thing for Lu." Of course, you have to put things in your store for a while. ”

After hearing Lu Zhan's words, these craftsmen suddenly became in a commotion, and many of them were stomping their feet and talking to each other. Lu Zhan heard these people say that the Chinese New Year is approaching, and there are still a lot of things to be busy with.

"Everyone be quiet, since Lu is here to invite all the masters to come to work, he naturally can't treat you masters." Lu Zhan clapped his hands and asked his subordinates to carry out a few large boxes, and after opening the boxes, they were full of white silver.

"The treatment of all the masters is in these boxes, whoever contributes more will get more, of course, if you want to go home, I will arrange for you to be sent back now."

These craftsmen swallowed their saliva after looking at the white silver, most of them agreed to stay and work, only one blacksmith master really had something to do at home, so he resigned Lu Zhan's retention.

After seeing the dozens of masters who stayed in the villa, Lu Zhan waved his hand and asked his subordinates to take out a design sketch that Lu Zhan had spent more than an hour preparing. After all, Lu Zhan was an art student, and when he was in school, he had a course called storyboarding, in which the course was to draw characters, backgrounds, and objects in a hand-drawn way.

"Sir, please forgive the villain for talking too much, what does it mean that this iron pipe-style thing is covered with a piece of wood."

"Yes, I started my apprenticeship at the age of thirteen, and I have been a blacksmith for twenty or thirty years, and I have never seen anything so chic."

When the blacksmiths had doubts about these Lu Zhan's design sketches, the gunpowder masters also looked at Lu Zhan in confusion.

"These are the work of the blacksmiths, and we gunpowder makers are here to do something."

Faced with the doubts of the blacksmith and the gunpowder master, Lu Zhan smiled and did not answer, but just asked the blacksmiths to make the barrel first. Took the gunpowder master to another place.

The blacksmiths were also led by Duan Xiaohan to the blacksmith shop specially made by Lu Zhan, this blacksmith shop was much larger than their own shop, the blacksmiths looked at the surrounding equipment, and reached out to touch it again.

"These tools are of the highest quality, but these steels are of the highest quality."

These blacksmiths were very satisfied with the tools, but these blacksmiths didn't know why Lu Zhan used these steel to forge them.

In fact, this is not Lu Zhan's stinginess, it's just that the musket is to be put into large-scale production, and if it is all produced with good steel, the cost is too great. In times of war, the performance of weapons is often compromised on production and reliability, and the AK series is the best example, which is cheap and practical and suitable for mass production.

When the blacksmiths lit the furnace and prepared to start casting the iron pipes drawn by Lu Zhan, Lu Zhan led the gunpowder masters to the warehouse where gunpowder was hoarded.

The gunpowder here was bought back by Lu Zhan, and the price of gunpowder in Yanzhou rose a lot for a while, and many foreign merchants saw that it was profitable and also transported gunpowder in the direction of Yanzhou, and even the old rival Zhijia also acquiesced to the caravan loaded with gunpowder to go to Yanzhou, after all, this gunpowder is not a daily necessity or a military material, so that these merchants can still bring taxes to themselves in the past.

"Sir, what are you hoarding so much gunpowder for?" A gunpowder craftsman couldn't believe his eyes, the huge warehouse was full of mountains of black powder and raw materials, and it would be unimaginable if there was a little spark.

"All of you gunpowder masters have many years of experience, and whoever can make the most powerful gunpowder in the prescribed amount today will receive a reward of fifty taels of silver."

These gunpowder craftsmen gasped, there was so much reward. However, in order to exert the greatest power in such a lost volume, the ratio of various substances will test the experience and skill of the gunpowder master.
