Among the five hundred craftsmen, there are blacksmiths, and the most casting craftsmen are. As soon as Liu Hongjian finished speaking, he stood up from the craftsmen and hulala out of the craftsmen.

Liu Hongjian handed over the drawings in their hands to them to circulate and view.

There are four drawings, two of which are decomposed. The first one is an object shaped like an iron hammer, and the second one is a thick cylinder with a hollow and a hole is opened below.

A few younger craftsmen were quick-witted and could not see any of them when they took them in their hands.

"Mr. Marquis, are you going to create a new weapon for the Beijing camp? But look, this is just an iron hammer!" The young man scratched his head and handed the drawings to the old craftsmen behind him in a embarrassed manner.

Liu Hongjian smiled but didn't answer. What an iron hammer is a must-have artifact for every household in the 1980s and 1990s.

The old man from the craftsman is almost fifty years old. He has been using iron tools for his whole life, and his hands are covered with thick calluses.

He frowned deeply, stared at the iron hammer-like drawing for a long time, until he turned to the second page of the decomposition description, and seemed to see the word "coal", and then had an idea.

"Mr. Marquis, is this object related to the coal stones you pulled over?" Lao Sun asked tentatively.

"Well, it's quite smart, not like these naughty young people! This thing is called a coal pellet machine!" Liu Hongjian said, pointing to the first drawing.

He has not only seen the old twelve-hole handmade coal briquette machine, but also used it.

When he was a teenager, in order to save money, the coal balls used for burning fires were made by hand using this thing.

I bought a coal powder crushed by a machine from a coal bulb factory, mixed it with a small amount of clay and mixed it with water, put the coal bulb machine into the coal slime and pressed it down hard until the coal slime fills the coal bulb body, and then dip it in the wood foam.

Press the head of the briquette machine in the open space, and a fresh briquette is made. After drying for two days on sunny days, you can keep your life warm.

Another drawing is a coal ball furnace. This thing is even simpler. It is nothing more than making a hollow mold with a chassis, watering it with iron, and then polishing it by a craftsman.

After listening to Liu Hongjian's explanation, the group of blacksmiths and casting craftsmen were stunned and shocked!

Isn’t the Marquis a soldier? How come he still understands the skills of our blacksmiths? Judging from the Marquis’ situation, has the Marquis even used this thing called a coal bulb machine?

Great! Great! A group of people even forgot their words, all watching Liu Hongjian explain with joy.

"Who is confident of making this thing?" Liu Hongjian said after the explanation.

In fact, when I was explaining just now, several literate craftsmen had already read the decomposition of the drawings. Although they were all simplified Chinese characters, most of the characters at the end of the Ming Dynasty were no different from those now.

The most difficult thing about this thing is the body of the briquette machine. The handle of the briquette machine is alive, and the twelve iron rods and the ball cover are also alive. The combination of the two is responsible for pressing the coal slime into shape and pushing it out.

This is an old antique that has been eliminated in later generations, but at the moment more than 300 years ago, it can be regarded as an epoch-making invention!

The few most active young people just now became depressed, and they made simple objects such as hoes and sickles. This thing doesn’t matter!

"Mr. Marquis, I may be able to give it a try!" Lao Sun bent down and saluted, and said humbly.

Your uncle is still your uncle! It’s not okay to sway if you are less than half a bottle!

"It's easy to say, the drawings are here. You can all start construction at the same time. Whoever develops it first will be rewarded!

Well... I will reward 500 taels of silver, and the craftsman's household registration can be converted into free self!" Liu Hongjian said after thinking for a moment.

He had already obtained this privilege from Emperor Chongzhen, and this would be a weapon he used to inspire craftsmen to work hard.

Five hundred taels of silver are not enough to change a certain craftsman's family, but removing the shackles of craftsmanship means that your children will no longer have to be bullied like him and be poor for a lifetime.

He can participate in the imperial examinations and become an official, do business, and farm and pick mulberry trees...

And now... the Marquis naturally counts his words.

No one knows how many humiliations these craftsmen have endured. Just this sentence is enough to make all craftsmen crazy.

A group of young people took the drawing and surrounded Lao Sun's head in an instant. They hoped that Lao Sun would give him advice, but other colleagues shook their heads because it was simply impossible.

China has been around for five thousand years, and its craftsmanship is passed down from the teacher's lineage. This is the skill of making a living. Unless it is your own son, how can it be passed on to outsiders?

"There are conditions for craftsmen to remove the registry. They need to compile the skills they have mastered into books and hand them over to the file to deal with them."

Liu Hongjian frowned slightly. For thousands of years, many skills have been lost in China. Most of the reasons are caused by this kind of teacher's word of mouth and not paying attention to the book.

With the conditions for delisting, even if you share what you have learned, there is nothing unfair. Anyway, your children don’t have to be a craftsman anymore.

In order for their descendants to no longer be bullied like them, most craftsmen don’t care much.

In fact, the use of coal is not limited to honeycomb coal. After all, these are anthracites that do not produce toxic gases, and they are burned in large pieces. There is no big problem when paying attention to ventilation.

Honeycomb coal is troublesome, not only does it have to smash the coal stone into pieces, but it also needs to be remade, which makes the process troublesome.

Fortunately, the labor force is really not worth it, and most of the craftsmen in ancient times had the spirit of craftsmanship, unlike later generations who could cut corners, and be stolen and never work diligently and down-to-earth.

Moreover, the promotion target of honeycomb coal is rich, and coal is several times more resistant to burning than charcoal, and the heat released is higher than charcoal. Moreover, charcoal is not only more troublesome to make, but also has a bizarre cost.

In the late Ming Dynasty, ten kilograms of charcoal cost two cents of silver, but what about coal? In terms of output, one hundred kilograms are less than five hundred cents of copper coins.

A piece of discus can be placed on the top of the coal ball stove, a hole is opened on the side, and an exhaust pipe can be opened outside the window. In addition to heating, the upper part can also boil water, heat tea, cook, and cook for several purposes in a furnace.

Besides, honeycomb coal and coal ball stove are not much taller than charcoal basins when put in the house!

Liu Hongjian could almost imagine that if he really made this thing, he would definitely make money.

Another method is to target ordinary people's economical and practical models. It is nothing more than building a stove with mud and stones, and knocking the large coal into small ones and then using it.

After explaining many things, seeing that it was getting late, Liu Hongjian was ready to go home amid everyone's gratitude.

"Oh, Lao Yan, you three will remember to come to my husband's mansion later. It's the New Year, let's have some fun together!" Liu Hongjian said as he got on the horse.

"The subordinate officials obey the order, even if the lord doesn't say anything, the subordinate officials and the other lords have something to report to the lord!" Yan Yingyuan bowed and gave it to him!

"What official do you want to be? We are so polite. If you have something to do, I will take a step first!"

After saying that, Liu Hongjian walked home by surprise.
