The so-called King of Hell is easy to mess with, but the little ghost is difficult to deal with.

The emperor is also a human being. As long as he is a human being, he will have a cruel and cute side. It is actually okay to make some harmless jokes occasionally.

Zhu Di was originally a martial artist. The biggest feature of martial artists is that they like knives and horses. Hao Fenglou's bets are not just about competing with the Japanese. In a sense, it is actually a bet with Zhu Di.

Zhu Di hoped that Hao Fenglou could open his eyes. He loved good knives very much. However, as a pragmatic person, he did not like the kind of swords and swords that were exhausted and spent countless human-made treasures. In his eyes, such weapons cannot be popularized, and it is useless to use them, and the decoration is more meaningful.

However, Hao Fenglou often unexpectedly, and he felt a little expectant, hoping that Hao Fenglou would give him a big surprise.

So even though he knew he was deceived, Zhu Di still glared and said, "You draw up a charter and I will just follow it."

Hao Fenglou made a lot of money, so he quickly drafted a charter, with 100 skilled craftsmen, and a large amount of coking coal and several ready-made utensils from various manufacturing sites.

These skilled craftsmen were selected from the Nanjing Manufacturing Bureau, and their skills were excellent. However, Hao Fenglou explained in advance that once these people followed him, they would be able to take off their craftsmanship, keep food and accommodation, and be able to take over the family. However, there are also conditions, so they would not come out again in the future and work for Hao Fenglou from now on.

The entire manufacturing bureau was like a blowout, and the workmanship was supervised here every day. Most people were numb and wanted to change it. But now Hao Qianhu gave them a chance, but how good it was. But they didn't know, but being able to get rid of the craftsmanship was enough to attract them.

The management of the imperial court was very chaotic. The officials were working hard and it was common for them to be greedy for their food. In order to deal with the imperial court, the tasks were also heavy. They carried a whip and shouted at them to work every day. The hardships can be imagined. What's even more terrifying is that they almost did slave labor. With the status of this craftsman, their descendants were like this. It was chilling to think about it.

It doesn’t matter whether your destiny changes or not, but for most people, whether their descendants can change their destiny is their most concerned thing, so 70% of them are willing to follow Hao Fenglou. Hao Fenglou picked some experienced craftsmen and sent them to the camp directly.

As for the coking coal used for iron smelting, they need as much as possible. The eunuchs from the Nanjing Construction Bureau were eager to take it away. They wanted Hao Fenglou to take it away. Because there was a lot of oil and water for purchasing coking coal, and Hao Fenglou took away as much as it could, they would have to purchase it at that time and could regain it again.

Hao Fenglou didn't choose many other tools. There were very few that could catch his eye, but there were also a few big cars.

Immediately afterwards, Hao Fenglou hurried to Qianhuyuan and explained to Zhou Fang, Zeng Jian and others that he had important things and was afraid that he would not have much time to come this month, so he would let them do it well and go to his mansion to upload news.

Then he returned home again, and did not explain the truth to his parents. He just said that he had a secret mission to go out for a long distance, so he bid farewell.

Everything was ready, and Hao Fenglou, who had changed clothes, set out for his future and the dream of changing the world in slightest way for his time travelers.

"Actually... Mr. Hao is still quite noble..." Hao Fenglou thought fantasically, and he was so happy.

"This is the spirit of ownership, although it is for fame and profit."

When they arrived at the camp, Hao San was arranging new craftsmen. These craftsmen arrived at the new land, and their families had been picked up in a few months. At first, they were a little uneasy, but when the meal started, they saw white rice, broth and spoonfuls of dishes. All their worries were thrown away. There was nothing to say, grab them.

Only when eating can these guys be so enthusiastic. For the craftsmen at this time, having food and being able to eat is happiness. If they can still eat well, it will be like smoke from the ancestral grave.

"I'm here and I plan to stay here for a long time. Alas, the camp is too dirty and messy, uh... don't mind squeezing."

Hao Fenglou carried his bedding and came to Zhu Zhiling's residence halfway inside and outside. It was very fine, with blue bricks and white tiles, and the inside was cleaned. In order to prevent mosquitoes, white dust was sprinkled outside.

Zhu Zhiling's first reaction was silence.

After hesitating for a long time, he finally said, "You sleep in the outer room, I sleep in the inner room."

Hao Fenglou said in tears: "At first, I thought that the beautiful sister would protect me and let me sleep in the inner room."

Zhu Zhiling knew that he was a man full of nonsense, so he took his quilt shop and made his bed.

You can't eat and live here for nothing. Hao Fenglou remembers his mission. When Zhu Zhiling asked about his origin, Hao Fenglou said it in detail.

"This time I will refine magical weapons and open their eyes."

Zhu Zhiling couldn't help but smile: "It turns out to be a blacksmith."

Hao Fenglou scratched his head and said, "I understand everything, I understand a little bit."

On that day, Hao Fenglou had to settle down the new craftsmen, but he didn't go to the camp to join in the fun. He lived here at Zhu Zhiling. He lay on the bed, pillowing his head with both hands. The bed was temporarily built. Two benches were equipped with wooden boards. After turning over, it creaked. The lights in the inner room were turned off. Hao Fenglou suddenly said, "Beautiful sister, are you afraid?"

No movement.

Hao Fenglou coughed.

At this time, the inside room said, "What are you afraid of?"

Hao Fenglou said: "Actually, I'm a little scared. When I came to Nanjing, I was always restless when I was sleeping and always felt that everything was like dreaming."

"Um……"

Hao Fenglou said, "But I feel much more at ease with you. The sky falls, and you...uh...I'm blocking me." Hao Fenglou shook his head, feeling that he was quite stupid, closed his eyes and went to bed.

When he woke up the next day, Hao Fenglou began his iron-smelting plan.

When he arrived at the camp, he recruited all the blacksmiths and immediately said, "Since it is to smelify iron, why use charcoal instead of coking coal?"

Hao Fenglou knew that coking coal had been widely used a long time ago. Using coking coal to make iron can improve efficiency on a large scale and reduce costs; after all, charcoal is hard to obtain, and it also requires burning charcoal, which takes a lot of manpower in the middle.

An old craftsman stood up and said, "Young master, it's not just coking coal. In the manufacturing process, the villains use coke to make iron."

Coke...

Hao Fenglou was stunned for a moment, not expecting that coke iron smelting had already begun to popularize coke iron smelting in the early Ming Dynasty. You must know that in the West, the British invented the coke iron smelting method more than two hundred years later. Many people even concluded in later generations that the invention of coke iron smelting has a great causal relationship with the British Industrial Revolution. If it were not for the emergence of coke iron smelting method, the industrial revolution would not have been so smooth.

"Damn, my ancestors are so powerful, and now they have coke?" Hao Fenglou didn't recall it for a moment. He suddenly realized that something was wrong, because the so-called "innovation" he had mastered seemed to have become popular in this era, but since that's the case, why don't everyone use coke to make iron?

Hao Fenglou said to the old craftsman: "I dare to ask my father-in-law Gao's surname."

The old craftsman said: "The villain Huang Ting."

Hao Fenglou said: "Brother Huang, since he already has the method of charcoal iron smelting, why do he use charcoal to smelify iron? This is inconsistent."

Huang Ting understood that the young master was a half-baked person for iron smelting, so he had to explain: "The drawings arranged by the young master have very high requirements for iron quality, and if they are refined with coke, they will produce a lot of impurities. The iron produced is very inferior and is very easy to crack."

Hao Fenglou was stunned because in his knowledge, coke iron smelting is a method that has been widely used in later generations. Everyone will use it five hundred years later. How could the quality of the iron refined is worse than that of charcoal? This is unscientific.

Hao Fenglou didn't say much, just said, "Go and get some coke."

When someone came to take the coke, Hao Fenglou only took a look and couldn't help but smile.

Finally I know the key to the problem, because this coke is simply a semi-finished product. Simply put, coke is made of coke coal. The refining method is similar to iron smelting. It is fired at high temperature and finally the coke coal is made into coke. However, once the combustion is not sufficient and incomplete, the impurities in the coke cannot be removed, resulting in low quality of coke. Using this coke to smelify iron, naturally, even charcoal is not as good as charcoal.

Therefore, craftsmen would rather use charcoal than use coke to smel iron, because in their consciousness, the iron refined from coke is of poor quality and cannot meet the needs of Hao Fenglou's sketch.

Hao Fenglou couldn't help but sigh. He had already created the most advanced method in the world, leading others for hundreds of years, and completed a world-renowned innovation. Unfortunately, he did not continue to study it in depth after the innovation, and he missed this subversive creation.

Hao Fenglou said: "Go and get coking coal, grow the furnace, and re-extract the coke."

He summarized the reason. It is because the coke is poor and the coke is poor. To put it bluntly, the temperature for making coke is about 1,200 degrees, which is similar to the optimal temperature for ironmaking. However, Hao Fenglou estimated that it is difficult for ordinary blast furnaces and bellows to increase the temperature to this amount. It is good to have nine hundred. Therefore, the key to all problems is still the fire.

In a shed, the newly improved blast furnace has begun to be filled with coking coal. This blast furnace is higher than the current blast furnace, with a fireproof layer and a special air outlet. These are some improvements made by Hao Fenglou based on the memories of later generations. Although it is impossible to make any leap forward, it is obviously much higher than that of this era.

Of course, whether it can be useful still needs to be tested.
