In order to prevent rebellion, private blacksmith shops are not allowed to produce weapons.
Once you are found to be forging weapons privately, it will definitely be a serious crime of confiscating your home and exterminating your family.
Therefore, the military's weapons could only rely on official iron workshops.
In Yingtian City, only the iron-making workshop of the Ministry of Industry is qualified to make weapons.
These weapons are needed to arm the entire Yingtian City defenders!
From the fifth military camp guarding the capital to the Jin Yiwei, all their sabers will be made by the iron-making workshop of the Ministry of Industry.
Although this is a non-war period, the monthly loss of weapons in each battalion is a considerable figure.
So now the Ministry of Industry builds sixty swords every month, which is just a bottom line.
If the Ministry of Industry builds less than this number of swords every month, then the defenders in Yingtian City will not have enough weapons!
Zhu Yuanzhang wanted to see where Hu Changan was going to conjure so many knives after cutting down his working hours.
However, Hu Changan just smiled slightly and said: "Your Majesty, you are worrying too much. Even if you only work for half a day, the Ministry of Industry will produce more swords!"
Now, Zhu Yuanzhang was shocked.
Could it be that Hu Changan has done something amazing again!
You know, if the working hours are reduced by half while ensuring the quantity, then this means that the efficiency of the work department workshop has at least doubled than before!
It’s doubled!
Zhu Yuanzhang simply didn't dare to think about it.
If the efficiency of the Ministry of Industry was doubled, why would the Ming Dynasty worry about not having a strong army?
Those light cavalry can probably be directly armed into heavy cavalry.
This will definitely be a huge improvement in Ming Dynasty’s military strength!
Thinking of this, Zhu Yuanzhang's heart moved shamefully.
But Zhu Yuanzhang still didn't believe it.
There has been no major improvement in this iron-making method for hundreds of years. Why did this iron-making method take off as soon as Hu Changan came to the Ministry of Industry?
How could this Hu Changan be so magical?
"I want to see the iron-making workshop in person."
"yes."
Along the trail, Zhu Yuanzhang and his party came to the iron-making workshop of the Ministry of Industry.
In the ironmaking workshop, craftsmen are working hard.
Everyone was sweating profusely and working so hard that they didn't even notice Zhu Yuanzhang and his party.
The eunuch following Zhu Yuanzhang wanted to shout loudly, but was stopped by Zhu Yuanzhang's look.
Zhu Yuanzhang came to Weifu for a private visit, not a high-profile inspection.
Although Zhu Yuanzhang did not know much about the method of iron-making, he also knew that the strange-shaped blast furnace in front of him should be Hu Changan's improved masterpiece.
Zhu Yuanzhang paused.
I don't know what kind of surprise this Hu Changan will bring him.
Zhu Yuanzhang admired the strange-looking blast furnace for a while, then took a detour to see the craftsmen at work.
However, just by looking at it, he was completely stunned.
I saw that in the blast furnace, molten iron was flowing continuously like a stream.
And the group of craftsmen were quickly picking up the hot molten iron in containers and putting it aside to make swords.
There are at least a dozen swords being forged at the moment.
At this rate, let alone sixty knives a month, sixty knives can be made in two and a half days!
Zhu Yuanzhang was completely shocked.
In his vision, Hu Changan could increase the efficiency of iron-making by two or three times, which was incredible.
Who would have thought that Hu Changan would give him a huge surprise in a low voice.
How can this not increase efficiency by two or three times? This clearly increases efficiency by dozens of times!
If you operate it properly, Ming Dynasty's national power can be greatly improved!
Zhu Yuanzhang couldn't help but froze on the spot, breathing rapidly.
Even Zhu Biao was completely stunned.
He believed in Hu Changan, but he never expected that Hu Changan would give him such a big surprise.
This efficiency is definitely a step forward across the ages!
Zhu Yuanzhang and Zhu Biao were stunned for a long time before they came back to their senses.
After they came back to their senses, they were extremely grateful to Hu Changan.
Hu Changan is truly a national scholar!
At this time, Zhu Yuanzhang could not even think of asking Hu Changan about his working hours.
Hu Changan can improve iron-making technology to this level, so he must be quite accomplished in cultivating talents.
Maybe what Hu Changan said about creating new disciplines might actually be true!
Zhu Yuanzhang flushed with joy: "Hu Aiqing, you are really a great talent! Do you want to promote your two new subjects?"
"I think there are still too few people in the Ministry of Industry. How about you just teach the craftsmen in the city directly?"
"I allow all the craftsmen in the city to not work every afternoon and go to your place to attend classes!"
Zhu Yuanzhang was fine if he didn't complain, but when he made a move, he was very generous.
In Zhu Yuanzhang's mind, since Hu Changan had proved the usefulness of his theory with facts, it meant that Hu Changan's words were also correct.
If after learning theory, everyone can become a master like Hu Changan, then why not let more people learn it.
In Zhu Yuanzhang's view, the few people in the Ministry of Industry were still too few.
If you want to make trouble, it is better to make big things.
Wouldn't it be better if all the craftsmen in the city come to learn?
However, Hu Changan declined Zhu Yuanzhang's proposal: "Your Majesty, if there are too many people teaching at one time, I'm afraid it will affect the effect."
Zhu Yuanzhang was taken aback for a moment, but then he came to his senses.
He was too excited just now and lost his temper.
There are at least ten to twenty thousand craftsmen in Quanying Tiancheng.
All these 20,000 people came to listen to Hu Changan's class. Not to mention whether there were enough seats in the classroom, I was afraid that the people in the last row would not be able to see Hu Changan, and they could only see the back of the head in front of him.
Zhu Yuanzhang also laughed: "I'm sorry, Hu Aiqing, I was too excited just now. I made a mistake. I made a mistake."
However, Hu Changan confirmed part of Zhu Yuanzhang's idea: "Your Majesty, what you said about letting more people learn is good, I think."
"After all, a person's power is limited, and he may not be able to come up with the correct way to improve."
"But as the saying goes, three cobblers are as good as Zhuge Liang."
"If one person can't figure it out, then there is always one person out of a hundred who can figure it out."
"As long as we promote this one person's idea, wouldn't it improve everyone's overall efficiency?"
"I think otherwise, Your Majesty, you can set up a special academy, which will not teach the Four Books and Five Classics, but will recruit craftsmen from all over the country to spread my new discipline."
"In this way, the labor efficiency of all walks of life in our country will definitely be greatly improved!"
After Zhu Yuanzhang heard this, he agreed with Hu Changan's idea: "Pass it on and let the Ministry of Rites run a school to teach Hu Changan's new subjects!"
Zhu Yuanzhang wanted to see the efficiency of all craftsmen in the Ming Dynasty reach a higher level within his lifetime!
