The matter of the steelmaking workshop was settled, and Zhou Huchen, who had been under pressure, finally relaxed a little, and he returned to Datong Mansion with a good mood.

Not long after entering Datong Mansion City, holding the Tiger in his right hand and a large rattan box full of gifts in his left hand, Zhou Huchen appeared in the old lady's backyard.

Seeing the funny scene of being held in Zhou Huchen's hand, the tiger-headed tiger desperately danced his limbs to resist, but he was helpless against Zhou Huchen, and the old lady smiled and leaned back.

"Put it down, Xiaohu put down the second tiger, don't make trouble!"

The old lady spoke, Zhou Hu saw the opportunity to throw the Tuesday Tiger out casually, how could the Tuesday Tiger, who had been teased all the way, give up, he quickly got up, and then pounced on Zhou Huchen, this time - it was still a dragonfly shaking the pillar.

The unwilling Tuesday Tiger really had no choice, he had an idea, and "grabbed" the rattan box in Zhou Huchen's left hand: "It's all mine, it's all mine!" ”

"There's rouge gouache in there, it's good for you to soak the little girl, just take it!" Putting the rattan box on the ground, Zhou Huchen showed a playful smile on his face:

Of course, it won't be any rouge gouache, this rattan box is very heavy, inside is the gifts that Zhou Huchen bought for his family in Nanjing, these gifts include jade, rhino horn, small coral, tortoiseshell, and various jewelry, etc., although the objects are small, they can be worth a lot of money, Zhou Hu is a real rich man now, how can he be stingy with his family.

This time he went to Nanjing, Zhou Huchen also specially bought a sharp Longquan sword for Zhou Yuji and his little cousin Liu Wei, because it was inconvenient to carry, and it was still in the hands of Zhou Huchen's family.

Tuesday Tiger is the age of playfulness, the heavy rattan box was barely "snatched" by him, the rattan box opened, Tuesday Tiger was immediately dazzled. Soon after, the floor of the old lady's house was littered with all kinds of treasures, gold, silver and jade jewelry, which were precious to ordinary people.

The old lady didn't say anything to Zhou Huchen for buying these luxury things, after all, it was her grandson's filial piety, and she was most concerned about the granddaughter-in-law in Xuzhou, which was a lifelong event for her grandson, in fact, the old lady just saw whether Zhou Huchen was satisfied with the little girl.

Speaking of that beautiful little Lori, Zhou Huchen immediately twisted, his answer was intermittent, headless and brainless, but there was no accurate answer.

Understood, the old lady understood in her heart, this is very satisfied, otherwise, with Zhou Huchen's temperament, she would have already known how much bitter water she vomited.

At this time, Zhou Huchen's mother, Liu, also ran over, and saw Tuesday Hu, who was playing with all kinds of treasures and precious jewelry as mud on the ground, and Liu's heart ached. Hurriedly said hello to the old lady, Liu didn't care about asking Zhou Huchen about going to Xuzhou, she immediately squatted on the ground and coaxed Zhou Hu, and then hurriedly began to clean up.

In order to prevent the embarrassment of being questioned again by his mother, Zhou Huchen greeted the old lady, and he took the opportunity to run away

The family had a lively lunch, and gave the two Longquan swords to the cheap father Zhou Yuji and Liu Wei respectively, Zhou Huchen in order to avoid his mother's bombardment, he immediately ran out of the General Military Mansion without hesitation.

In fact, there is nowhere to go, and after patrolling the various school grounds in the barracks, Zhou Huchen has nothing to do.

After a long walk, Zhou Huchen Shi Shiran returned to the big wall of the workshop.

Entering the workshop, far away from his office, Zhou Huchen saw a person. There are hundreds of people in the workshop, and it is not strange to see people, but the strange thing is that this person is standing quietly in front of Zhou Huchen's office. This person is very regular, he stood in front of Zhou Huchen's door with his head slightly bowed, and stood in place without squinting, as if he was an old monk in his meditation.

"Captain Hou, is there something going on?" This person was clearly a craftsman in the steelmaking workshop, and Zhou Huchen estimated that something might be wrong with him, so he hurriedly stepped forward and asked:

Hou Yuanshan turned around slightly and bowed: "Yes, young marshal, the little one has something very important that he wants to give back to his son!" ”

"Then go to the house!" After Zhou Huchen finished speaking, he pushed the door and entered.

Waving his hand so that Hou Yuanshan didn't have to be polite, Zhou Huchen asked directly: "Don't be restrained, what is the matter with the head of the craftsman." ”

"That's right, villain remembers that you said you need the most haode steel, young marshal."

Zhou Huchen nodded and motioned for Hou Yuanshan to continue.

Hou Yuanshan showed a full face of expectation: "The villain has been relying on this steelmaking since he began to eat, and he is determined to make the most haode steel, but unfortunately, there has been no chance in Jiangnan, this steelmaking workshop is actually just producing general Suzhou steel, and the villain also has a way to make the most haode steel for the young marshal." ”

Zhou Huchen smiled, whether he came to work hard or to realize his ideals, it seems that this Hou Yuanshan still really has a way to refine more haode steel.

"Say it! What is the method? If it works, let's start immediately, and as long as you can make good steel, I'll double your salary, how about it! ”

Hearing Zhou Huchen's promise, Hou Yuanshan hurriedly spoke: "Young Marshal Xie, I don't know if the young marshal has heard of coal essence?" ”

Jet! Zhou Huchen seemed to have a little impression, that thing seemed to be used for carving.

"Then tell me, what is this coal spirit?" This coal essence is estimated to be the same thing as the coal essence that Zhou Huchen thought of, Zhou Huchen asked directly:

"Back to the young marshal, this coal essence is the essence of coal and stone burning, and it is best used to make steel!"

Zhou Huchen instantly understood, this coal essence is really coal essence, not coal essence, it is clearly coke!

The best fuel for steelmaking should be coke, not coal or charcoal commonly used by smelting craftsmen in the Ming Dynasty, there is no secret to coke making, China / China is the first country to invent coking jishu and use coke on shijie; The invention of coke is one of the important scientific and technological achievements and contributions of the ancient Chinese people, which originated in the Song Dynasty and is of great significance for the development of the metallurgical industry and the development and utilization of coal. The ancient Chinese coking method mainly refers to the smelting of coking coal into coke in a local coke oven, which is different from the modern high-temperature dry distillation method.

The most direct reason why coke has not been used on a large scale in the next season is because of the cost, that is, the use of coke is too expensive, so it has not been promoted.

Talent is coming again!

Zhou Huchen's smile bloomed, there is no shortage of coal in Shanxi, this proposal is simply wonderful: "Will the head of the waiting group make coking coal?" ”

"The villain has never made coal essence, but he knows the method of refining coal essence, and the villain also knows that coal refining is much easier than steelmaking, so"

Every kind of jishu progress takes time to precipitate, and this is a typical example. The use of coke to make steel is not an invention, but the large-scale use of coke to make steel is absolutely unacceptable

Yes is a kind of progress, a huge progress. There are many impurities in the coal, and the natural quality of the steel is not good, but coke can completely avoid this defect.

Is it expensive to make steel from coke? It's not expensive at all, at least not for Zhou Huchen. Shanxi has no shortage of coal, no shortage of iron, no shortage of silver, and no shortage of people.

What the ancients needed was practice, while what Zhou Huchen needed was to point out the right direction and provide them with conditions. The dream Great Wall of Steel shook in front of Zhou Huchen's eyes, and Zhou Huchen's enemy was now not Li Zicheng, nor the brutal Manchu Qing, but time, because there was not much time left for him.
