Kunning Palace.
Ma Enhui was playing with Zhu Wenkui, and the maids and eunuchs were also around, enjoying themselves.
At this moment, a eunuch came over and reported: "Queen Qi, the eunuch in charge of the military battle bureau has arrived."
"Oh? I don't remember summoning troops for battle, so why did I come to Kunning Palace?"
Ma Enhui was a little confused.
"I asked them to come."
Zhu Yunwen walked into Kunning Palace, and everyone knelt on the ground. Ma Enhui gave a slight salute, and then saw the eunuch of the Bingzhan Bureau kneeling outside to salute him. There were also some red cloth coverings on the ground.
"Bring your stuff in."
Zhu Yunwen said softly.
Liang Xiu, the eunuch in charge of the Military Staff Bureau, quickly ordered someone to lift the things and carefully delivered them to the main hall of Kunning Palace.
Zhu Wenkui walked towards Zhu Yunwen and shouted immaturely: "Father, what is that?"
Zhu Yunwen hugged Zhu Yunwen and said with a smile: "That's a good thing. Let's go and see it together."
Ma Enhui entered the hall, and Liang Xiu took off the red cloth at Zhu Yunwen's signal, revealing three stoves.
The stove is square in shape, painted vermilion on the outside. There is a rectangular drawer at the bottom, which is responsible for collecting coal ash. There is a grate in the middle, which is supported by an iron grid and is responsible for carrying coal. It is covered with heavy lead and iron, and there is a small opening on it. , there is a layer of iron covering the small opening.
The upper side of the stove is extended outwards, where some utensils can be placed. The rear side wall adjacent to the top of the stove is designed with a smoke exhaust port, a hot water tank chamber, and a water inlet and outlet.
On the side, there are some small chimneys surrounded by iron sheets, which are made up of a row of pipes and resemble fences.
Ma Enhui looked at it carefully, but couldn't understand it. She looked at Zhu Yunwen and asked, "What is this iron lump?"
Zhu Yunwen smiled softly and said: "This is a good thing for us to make a fortune. Well, let's call it a greenhouse stove."
"Hothouse stove?"
Ma Enhui looked down and asked doubtfully: "Although it is different from an ordinary stove, how can a greenhouse be heated?"
Zhu Yunwen smiled and said: "At this time of spring, the weather is not cold anymore, so its effect is difficult to show. But since the queen wants to give it a try, then you can assemble it and add water."
Liang Xiu and others took the order, quickly spliced the chimney, then selected a wall, cut a small hole, and poked out the chimney. The end of the chimney was bent upward to prevent smoke from pouring back.
After connecting the radiator, arrange for people to fill it with water, and then take out the new briquettes. After igniting them with charcoal outside, they clamp them into the furnace and squat a hot water kettle made of iron sheets on top.
After cleaning up, the people from the Bingzhan Bureau left only three briquettes, then bowed and left.
Zhu Yunwen ordered people to close the door, then sat behind the desk and said to Ma Enhui, who knew little about it: "Since the incident in Chengqian Palace, I ordered the people from the Bingzhan Bureau to make this greenhouse stove, but they didn't even have the iron sheet." It won’t be mass-produced, which makes me very disappointed.”
"Batch manufacturing, how to mass-produce iron sheets? Isn't it just knocked out bit by bit?"
Ma Enhui asked with confusion.
Zhu Yunwen casually picked up the tea bowl, gently rubbed the tea cup, and said: "Queen, many ideas come from life, and the same is true for this batch manufacturing method of iron sheets."
"how?"
Ma Enhui came closer and asked.
Zhu Yunwen took a sip of tea and said to Ma Enhui: "Hasn't the Queen seen dough rolling? Comparing the dough to an iron block, just roll it out before it is completely hard. What's so difficult about this?"
"Huh? This?"
Ma Enhui was a little stunned.
Yes, the emperor is right.
Dough can be rolled out, so why can't iron balls be rolled out?
Why has no one thought of such a simple truth?
Although Ma Enhui does not understand iron smelting, she also knows that forging iron often involves burning molten iron, casting models, and then making utensils. But if you pour the molten iron into the hopper and use an iron wheel to grind it, you can easily get out the iron sheet.
We only need to repair the lower edge and then enclose it. Isn't it just an iron chimney?
"As for coal, I just don't understand why we have to use finely crushed coal. Can't we completely crush it, mix it with clay, and make it into blocks? Are there not enough bricks in this palace? We all know how to burn mud into blocks. Bricks, why don't you know how to make coal into bricks or blocks? Do you have to get a brazier, fire cabinet, or stove and throw coal blocks into it?"
Zhu Yunwen rubbed his eyebrows and asked somewhat depressedly.
Ma Enhui looked at Zhu Yunwen in surprise, then looked at the briquettes placed not far away, and sighed: "Compared with the emperor, I just feel too stupid."
Zhu Yunwen motioned Ma Enhui to sit down, and then said: "It's not that you are stupid, but that we people in the Ming Dynasty lack new ideas and lack the motivation to find new ideas."
If Zhu Yunwen was just a native citizen of the Great Tomorrow, a blacksmith, then he would be swinging the hammer day after day and making utensils.
They will never ask why coal is in the shape of lumps instead of cakes, nor will they figure out that iron sheets can be ground out instead of knocked out.
The limitations of the times and the repetitiveness of life prevent them from looking for new breakthrough possibilities, and they even decide in their consciousness that the ancestral craftsmanship is the best.
It is pitiful to say that there are countless inventions in thousands of years of history, but in the final analysis, there are too few scientists who really invent for the sake of invention.
In addition to the crystallization and precipitation of the wisdom of the great masses, some inventions just come from various "accidents".
Like gunpowder, it was an accident of the alchemist.
The reason is definitely not that the Chinese people lack wisdom, but that in the feudal era, there was no environment for innovation and no market for new things.
Take alcohol for example. It is obviously a purified product of alcohol, but it is still misunderstood as poison and people dare not try it. If the soldiers in the military camp were not often injured and wanted to verify the effect of alcohol, I guess the two kings would have had no choice but to use it on themselves. Got a cut on my body.
For another example, the Gunpowder Bureau under the Bingzhan Bureau has studied the improvement of fire cannons several times. Although it has not made a huge breakthrough, its range and power have been improved compared to the fire cannons in the early Hongwu period.
But what are the rewards given by the Battle Bureau?
Oh, no rewards.
As for them improving, isn't that what they should be doing?
There is no incentive mechanism, no encouragement, and no benefits. Who would bother to do research?
Don’t blame Ma Enhui.
Complacency is the norm for feudal dynasties with a small-scale peasant economy. They are accustomed to staying on their own one-third of an acre of land, although they occasionally stand on a high place and look into the distance.
But their feet will not leave.
Zhu Yunwen wants to change all this and give people imagination and innovation. Judging from the current education, it is difficult, too difficult.
There are only the Four Books and Five Classics, but no mathematics or physics.
Zhu Yunwen shook his head bitterly and looked at the boiling pot of water. The steam pushed open the lid of the pot, and a whining sound came from the spout, like a whistle urging...
