White cast iron?

Jiao Xu thought about it and asked tentatively: "Do you think it could be a problem with the iron?"

Before the burly man could say anything, a man walked out from behind Jiao Xu and said, "What do you mean? There can't be anything wrong with the iron we smelted!"

"Even if there is, it's a problem with iron ore!"

"Bullshit! All the iron mines in the world are the same. You can't make iron but you blame us for mining it, right? Ugh, that's disgusting!"

These craftsmen were rough people who were used to swearing on a daily basis. When they saw someone trying to put the blame on them, they immediately started quarreling.

As the Minister of Works, Fan Jingwen was frightened to see his subordinates being so unreasonable in front of the emperor. He walked up to the crowd and gently scolded them, "Shut up! This is the Huangji Palace, not the Ministry of Works. All of you shut up!"

All the craftsmen suddenly came to their senses and shrank back where they were, not daring to act rashly.

Chongzhen did not seem angry at all. Instead, he felt very relieved. This is how a normal person should be.

The behavior of these people just shows that they have not been corrupted.

Chongzhen coughed lightly and said, "I know that your original intention is not to shirk responsibility, but the idea of using iron as a mold is acceptable."

Everyone was puzzled, especially Jiao Xu and the burly man, whose eyes were full of doubt.

Chongzhen thought about it and made an analogy: "There are two pots in front of me, one is an iron pot and the other is a clay pot."

"For the same pot of water, after the fire under the iron pot is extinguished, the water in the pot quickly stops boiling."

"If you use a clay pot to boil water, the water will continue to boil for a while after the firewood is removed from the bottom of the pot."

"I think boiling water and casting cannons are similar in nature!"

Jiao Xu and the burly man were both craftsmen skilled in casting. After a moment's thought, they showed expressions of horror.

"Your Majesty's words have awakened me from my dream! I think I know why!"

The burly man couldn't help but say, "I know, I finally know! The iron mold cooled too quickly. If we pour the molten iron into the iron mold and then put it into the charcoal fire, the problem should be solved!"

"Your Majesty, can I give it a try?"

Chongzhen was very moved by his professionalism, so he asked, "What's your name?"

"I am Li Dalun, a native of Runcheng Town, Zezhou Prefecture."

Chongzhen nodded and asked the eunuch in the inner court to take him to the Armory for testing.

It was impossible to test-cast a cannon on site, but it was possible to use an iron mold to cast any piece of ironware. As long as it was not raw iron, it meant that Chongzhen's idea was feasible.

The rest of the people looked at Chongzhen in disbelief, feeling that the Ming emperor before them was omnipotent. Especially Fan Jingwen, whose worship of Chongzhen had reached a state of madness.

Before the bandits besieged the city, the emperor killed corrupt officials, recruited common people and won over the hearts of the people.

On the prince's way to the south, he planned and made plans, and won the battle thousands of miles away!

After the bandits besieged the city, they came up with all kinds of schemes and even sacrificed the lives of half of the brave guards to create fear in the enemy.

Some time ago, he asked Jiao Xu to improve the self-propelled musket, and now he is attacking the cannon. Is he still a human being?

I know so many things!

During the waiting period, Chongzhen was not idle and began to plan the future of the institute.

"How many people are there in the Research Institute?" Chongzhen asked Fan Jingwen.

"Your Majesty, there are a total of 116 people entering the palace to see the emperor today, including 37 from the Research Institute and 79 from the Manufacturing Bureau."

Chongzhen nodded: "The court is in a tense situation, so I am very concerned about the craftsmen who cast firearms! Others should not be discouraged. Once the war stops, you will have a place to use your skills."

"Those who are good at agriculture should guide the provincial governors, so that they can pass on knowledge from one level to another and help farmers increase production. Those who are good at water conservancy should work with the Ministry of Works to control floods. Those who are proficient in medicine should spread medical knowledge so that the people of the Ming Dynasty will no longer have to worry about the difficulty of finding a doctor."

"But your majesty..." Just as Chongzhen was brainwashing this group of people, Fan Jingwen raised a question: "According to your majesty's plan, within three to five years, a large number of craftsmen will appear in the Ming Dynasty. With more craftsmen, more things will be made, and more things will have to be sold at a low price."

"As time goes by, the things craftsmen make will become less and less valuable, and they may even lose money and have difficulty making a living!"

Other craftsmen have the same concerns.

Chongzhen smiled slightly: "Don't worry about this problem, I know what to do!"

He looked at the roof of the Huangji Palace, and the desire in his heart began to slowly grow.

There were only three things he did when he traveled to the Ming Dynasty: fight the Jiannu, fight the bandits, and embark on the great voyages!

In the second year of Yongle, Zheng He sailed to the West for the first time. In the eighth year of Xuande, Zheng He returned from his seventh voyage to the West.

Although there were records of diplomatic missions to the West later, they could not be compared with Zheng He's.

Historically, the Age of Exploration is also known as the Age of Discovery, referring to the extensive transoceanic activities and major breakthroughs in geography initiated throughout the world, especially in Europe, from the 15th to the 17th century.

He and Daming must catch the last ship on the sea voyage!

Unlike European colonialism, he wanted to practice economism.

In this feudal era, without industrialization, only developed handicrafts could support ocean trade!

These craftsmen are the strong backing of ocean trade!

"It's done, it's done!"

Just as Chongzhen was fantasizing about the future, Li Dalun ran in with a piece of iron.

He held the lump of iron up in the air for demonstration.

There is a broken piece on it, and the cut is gray, obviously not white iron!

Looking at Li Dalun's crazy appearance, Chongzhen quietly clenched his fists!

The Ming Dynasty was indeed full of talented people!

The iron mold casting method not only solves the problems of time and cost, but most importantly, it introduces standardization.
