The black stone he mentioned was anthracite, and it was also a high-quality anthracite. Chen Wanrong thought it was too vulgar to call such a quality anthracite black stone, but it was also vivid and met the requirements that the villagers understood as soon as they heard it. He reached out to take it from Zhang Deming and had a heavy texture. He secretly praised Zhang Deming's agile reaction to the black stone and coal, and smiled and said, "Master Zhang, this thing can be used to make coking and then make steel."

"If this thing can make steel, that's fine. There are so many in the west of our Luojiadian, as much as you want." Zhang Deming looked excited and then asked: "Master Wanrong, I don't quite understand what you said about charcoal. Can you please tell me again?"

Now he calls Chen Wanrong "Master Wanrong" instead of calling him his name directly, that's because Chen Wanrong's class was convinced by him.

Coking is extremely important for steelmaking and has a great impact on the quality of steel. It is necessary to emphasize it again. Chen Wanrong agreed: "Master Zhang loves to listen, so I will tell you to know. Please correct me if you don't." Humility is Chen Wanrong's virtue, and I have never forgotten a little humility.

Steelmaking with coke is a major advance in the history of steel and is a milestone. It is not an invention of modern technology. This technology was used on a large scale in the Ming Dynasty. The blast furnace of the Ming Dynasty was as high as nine meters, and the steelmaking of the Ming Dynasty was semi-continuous. It transferred the molten steel from the blast furnace to another furnace for processing and directly obtained steel. It was precisely when China mastered such advanced technology that the steel produced by a large steelmaking farm in China was equivalent to the total output of a country in Britain at that time.

Chen Wanrong believed that it was unrealistic to promote modern steelmaking technology in the Tang Dynasty. With the wisdom of the Tang people, there would definitely be no problem to reach the level of steelmaking in the Ming Dynasty. The quality of steel in the Ming Dynasty was similar to the starting point of chemical engineering. As long as it reached the level of the Ming Dynasty, it was very likely to make plates and make chemical equipment. Chen Wanrong couldn't help but feel excited. He sorted out his ideas and explained the coking technology to Zhang Deming again, loading coal, pushing coking, quenching coking, and screening coking. It was heard that Zhang Deming's neck stretched longer than a giraffe.

"Master Zhang, I know so much about steelmaking. I would like to ask you for advice if you don't want it. If you can ask your respectful teacher, Master Ye, that would be even better." Chen Wanrong summarized this.

If blast furnace iron was promoted in the Tang Dynasty, it would comprehensively improve the quality of the Tang Dynasty's steel and trigger a major change. This is a huge system project, requiring extremely large manpower, material resources and financial resources. With Zhang Deming's strength, it is impossible to complete it, let alone the children of his own poor family.

There are many chemical products that Chen Wanrong can make, but due to the scientific and technological level of the Tang Dynasty, it is difficult to make the equipment he needs. If a breakthrough is achieved in steel, everything will change. A new world will appear in the Tang Dynasty. Only then can chemical engineering take root in the Tang Dynasty and avoid becoming a Taoist magic and immortal technique boasted by alchemists and used to deceive people.

Thinking about this bright future, Chen Wanrong couldn't help but be very excited.

To achieve this leap, we can only rely on the wisdom of the Tang people and the power of the court. Ye Tianheng is a master of the military weapon supervisor. His vision will be very sharp and he will not be unable to see through the benefits. With his influence and appeal, it may affect the court's decision. You must know that the Tang Dynasty attaches great importance to technology and improves the quality of steel, which will make the Tang army stronger. With this, the court will do its best. Chen Wanrong then specially reminded Zhang Deming.

This was deeply agreed by Zhang Deming. He patted his chest and raised his voice: "Master Wanrong's words are so reasonable. With my ability, how can I make good steel? When I handle Zairong's sword, I will tell the master to listen to his teachings."

"Then aren't you going to Chang'an?" Chen Wanrong was very anxious about the steel issue and asked hurriedly.

Zhang Deming smiled and said, "Master Wanrong doesn't know anything. My master is old and has retired. He returns to our hometown in Ning County to enjoy his old age. Otherwise, how could I be the teacher of him?"

While talking, Zhang Deming installed the hilt of the sword. When he rushed to see Ye Tianheng, his efficiency improved a lot. He installed the hilt of the sword in a short while: "Just grind the sword."

Chen Zairong was very familiar with him, knowing that his current thoughts were not used in this regard, so he took the sword from him with a smile: "Master Zhang, I will do it myself, if you have any questions, you will do your business in advance." His eyes were staring at the sword, unable to let go of it.

How could a sword practitioner not understand the skills of sharpening swords? Chen Zairong not only knew, but also had great attainments. The sword he polished was very sharp. Zhang Deming followed the way and handed over the ready-made scabbard: "Then you guys do it yourself."

"Okay, no problem." Chen Zairong took the scabbard, put the scabbard into the scabbard, hung it around his waist, shook his waist, and looked at the sword around his waist, happily, bright eyes flashing.

"Master Zhang, how much does this sword cost?" Chen Wanrong reached into his arms with his right hand and was about to pay.

Zhang Deming's eyes rolled, but he was not grateful: "Master Wanrong, what's wrong with you? Do you still want to pay? You have taught me so many good things, aren't you ruining me?"

"Master Zhang, you deserve this money. This is the best steel. You have spent a lot of effort. I'm sorry for you if you don't pay." Chen Wanrong is not the kind of person who likes to take advantage of others. He has to pay for his own things. This is a personality problem.

Zhang Deming refused: "Master Wanrong, don't mention the money. When this kid makes a fortune in the future, let him pay for it himself, and a meal of wine."

The meaning of the words is already very clear, and I refuse. Chen Wanrong sighed in his heart that the simplicity of ancient style. Such a rare good steel must be sold for at least three or five jin of coins. Zhang Deming never even had the idea of ​​collecting money: "Master Zhang is so kind, I will accept Zairong on behalf of Zairong. If Zairong really makes a fortune in the future, I will definitely repay you with this affection."

Zhang Deming is so sincere, and Chen Wanrong is not inconvenient to use money to despise his sincerity, that's too vulgar.

"Master Zhang, please rest assured. If the sky won't let me down, I will really have a bright future. I will definitely remember your sword gift!" Chen Zairong clasped his fists at Zhang Deming and said sincerely.

Zhang Deming smiled and patted Chen Zairong's shoulder: "You kid will be successful. You give a beautiful woman and a sword to a martyr. I don't worry, this sword is worth it! I heard from my master that all famous generals love only three things: military books, swords, and fierce horses! You kid now have a sword, and there are many in the military books library. You should use more thoughts to read. As for the fierce horses, your kid's life is miserable." He sighed deeply.

Horses in the Tang Dynasty were very expensive. If soldiers brought private horses into the army, the government would subsidize 25,000 yuan. One thousand yuan is a one-two tael of silver. The official price of a horse is twenty-five taels of silver. The market price will fluctuate a little, but the gap will not be too big. Chen Zairong's family is extremely poor. If he wants to own a top-notch horse, it would be like a beggar who wants to drive a BMW sedan, which is too unrealistic.

Zhang Deming's family background is much better than Chen Zairong, but it is still unrealistic to sponsor a good horse to Chen Zairong, so he regrets it.

Chen Zairong not only loves weapons, but also likes horses, but his family is extremely poor and cannot afford it. In order not to worry about his parents, this thought has been hidden in his heart and has never been revealed to others. Zhang Deming's words made his mind feel sad when he said something about him. Chen Wanrong saw it and thought that it would be a pity if a talented man like him did not have a good horse to accompany him. He had to find a way to buy him a good horse.

Just as Chen Wanrong turned his mind, Chen Zairong's expression had returned to normal and said a heroic saying: "Famous and wealthy man should take his own favor! What's more?"

"Ambition! You are worthy of being a man! In the coming year, you will definitely gallop on the battlefield!" It is really admirable to have such lofty ambitions at a young age, and Zhang Deming was greatly inspired.

Chen Wanrong heard the grief and anger beyond his bold words. His parents' obstruction made him unable to roam on the battlefield. He was unwilling to let Zhang Deming stir up his sadness again and said, "Master Zhang, then we will say goodbye."

"Go away!" Zhang Deming saw him off: "I should have kept you there for a while, but I want to see the master. The family will not speak two families. I am in love with this kid, so I won't say polite words."

Zhang Deming sent Chen Wanrong and the others out, said to the sound and walked back into the house.

After leaving the blacksmith shop, Chen Wanrong's expectations became stronger and stronger: make high-quality steel early and make chemical equipment early!
