The Ming Dynasty started with caution

Song Jing pulled the bellows hard, and he no longer dared to mess around.

Decided to study hard with the master and observe every step carefully. Master Yan was cautious in doing things, but he got carried away because of improving the silkworm method and caused a big disaster. At this moment, he felt guilty.

He looked a little fascinated.

It turns out that to forge ironware, you need to use fried wrought iron as raw material, which is then red-hot and forged into shape.

However, not much iron can be smelted from one furnace of iron ore. If you want to increase the amount of iron tools, you must first increase the amount of wrought iron produced.

In this way, it is necessary to increase the amount of iron ore invested, so that more iron will come out.

Seeing him working so hard, the old master of the iron shop sighed: "Xiucai, if you don't concentrate on getting fame, do you want to be a laborer like an old man in the future?"

Song Jing lowered his head and was a little embarrassed to say: "As soon as I joined the teacher, I did a heinous thing and humiliated the teacher."

The old master's smile was a little narrow: "Can you still do bad things?"

"Xiaosheng... blew up Wang Gong's factory."

The old master's expression suddenly froze.

Song Jing anticipated his reaction, and blowing up the weapons bureau was tantamount to murder and arson. If his mentor hadn't shouldered the blame for him, he would have been in prison by now.

In short, he wanted to try this iron method again.

Only seven days have passed,

Zhou Yu went to Yan Chengjin and cursed: "My dear nephew, Song Jing is going to demolish my smelting factory! If it weren't for your sake, I wouldn't let him go to the iron smelting factory even if I beat him to death. Unless, you Give me money, yes, give me money.”

The person who guided Song Jing to the iron smelting factory was naturally Yan Chengjin, otherwise, no iron smelting factory would want a weak scholar.

"What is Song Jing going to do?" Yan Chengjin asked in confusion.

Zhou Yu said angrily: "He wants to build a big furnace in my smelting factory. He said that it will be made of giant wood and salt clay. Giant wood is not cheap. It is better to make it according to his own method. Can he make it! This guy also needs to use fire arrows. , good iron charcoal will not burn.”

Isn't this exactly the method I gave him?

The iron-making furnaces of the Ming Dynasty were very small and could hold less iron ore at one time, so the amount of iron produced was naturally less.

But as the furnace got bigger, furnace temperature became a problem again.

To heat a large stove, a lot of heat is required.

Therefore, Song Jing had to use fire arrows.

The fire arrow is a kind of fire ink made from hard wood strips. The flame is stronger than coal, and when it burns and breaks, it will not turn into debris and block the vents, allowing the blower to fully function.

The structure of the piston blower used today is consistent with that of modern blowing equipment and is extremely efficient.

Yan Chengjin was overjoyed and said to He Neng: "Go to the warehouse and get five hundred taels of silver."

Zhou Yu was dumbfounded.

Yan Chengjin was even richer than himself. It was strange for him that a scholar went to the iron smelting factory. Zhou Yu was surprised: "My dear nephew, is it possible that this scholar has some background?"

Yan Chengjin thought about it carefully and said, "He is a disciple of Mr. Zeng Jian, the current minister of the Ministry of Industry and the prince."

Zeng Jian?

Zhou Yu blinked, he knew Zeng Jian.

At first he wanted officials from his hometown to join the Ministry of Industry and asked Zeng Jian to recommend him, but he refused. Didn't he not accept students?

However, although he had heard about the bombing of the Ordnance Bureau, he did not know that it was Song Jing who did it, otherwise he would not dare to keep him in his iron smelting factory.

When Zhou Yu went to court, he only cared about floods and droughts. When the price of grain and salt rose, he immediately transported it to sell.

"Five hundred taels of silver can buy a nice small courtyard in the capital and build a stove." Yan Chengjin handed him the five hundred taels of silver.

Zhou Yu took it with a smile: "My nephew is so happy! But I still don't understand, why did my nephew ask him to build a stove?"

"Of course we should improve iron smelting and exchange Ming Dynasty's iron tools to the Franchi Kingdom."

Zhou Yu's smile gradually disappeared. Why didn't you say that His Majesty is your real biological father?

After taking the money, he left happily, but he still felt that something was wrong. Yan Chengjin was so generous.

Go back and ask that boy Song Jing!

Zeng Mansion,

Zeng Jian was personally supervising the renovation of Wang Gong Factory these days and had no time to take care of anything else. He only thought of Song Jing when he was free today.

"Yixian, if you don't understand anything, feel free to ask me questions."

Song Jingdao: "It is already a great favor to allow students to enter the study room to read. I don't dare to bother my teacher anymore. The students will definitely work hard to gain fame and live up to their teacher's expectations."

Zeng Jian nodded. He really wanted to recruit Song Jing as his son-in-law, but unfortunately he already had a family.

"Master, someone from the palace has come and brought many things." The servant said happily.

Han Wen, the Minister of Rites, and Xiao Jing, the Superintendent of Rites, came in person, and the prince's wedding was finally put on the agenda.

Zhu Houzhao slipped out of the palace again and quietly came to Yan's Mansion. He looked directly at Yan Chengjin and became suspicious: "Old Gao, I'm getting married. Why hasn't Zhang Yong gotten back my betrothal gift? What a shame in the world." Is he really poisonous?"

How long does it take to hike to Indu?

Yan Chengjin doesn't know either.

It cannot be measured by the standards of the previous life. After all, the road conditions are completely different. After the sea ban, the Silk Road was rarely traveled by people and may have become deserted.

There are often horse bandits in the northwest. Even Tang Monk needs four bodyguards to protect him when he goes there.

Yan Chengjinhun didn't care: "I'm afraid Eunuch Zhang has failed. Your Highness should forget about him."

Zhu Houzhao stared at Yan Chengjin with a smile, a meaningful look.

Yan Chengjin snorted coldly and ordered someone to go to the study and get the Shanhaijing: "Your Highness, read it yourself. Is it written on it that it is the Kingdom of Sindhu?"

Zhu Houzhao widened his eyes. There really was a Kingdom of Sindhu. He blinked seriously: "Do you think I should send another person?"

"I'm afraid it's too late to go now."

"What about my betrothal gift?" Zhu Houzhao pinched Yan Chengjin's neck.

In his own home, Yan Chengjin was not afraid of him. He hurriedly shouted: "Didn't you see him beat me? Come on, beat him!"

He Neng and others looked embarrassed. Everyone knew that this Mr. Zhu who came to the mansion every day was the prince of the dynasty. How could they dare to go up and fight.

"Mr. Zhu, don't hit my young master. If you want to hit me, hit me!"

After a while, Zhu Houzhao asked: "Old Gao, what about my betrothal gift?"

"It's not difficult. Wait here. I still have a way." Yan Chengjin tidied his clothes and walked out the door.

"I want to go too."

The sedan bearers carried the sedan all the way to Li's house.

Zhu Houzhao was about to go in, but was stopped by Yan Chengjin: "Your Highness cannot go in."

"Why?"

"Your Highness rejected Lord Li's daughter. Wouldn't it be embarrassing to see Li Qing'e later?"

Yan Chengjin was afraid that Zhu Houzhao would regret seeing Li Qing'e's appearance and would cancel Zeng Jian's marriage.

The matter would be serious.

Zhu Houzhao thought about it and sat in the sedan waiting.

The doorman knew that Yan Chengjin was Li Dongyang's student, so he invited him to the main hall.

Yan Chengjin had just sat down when he saw Li Qing'e again. She was holding a cup of tea in her hand, and she had a scholarly temperament, quite like Li Dongyang.

She put the tea on the desk: "My father always likes to take a rest after lunch. Please wait for a while."

"No problem."

Li Qing'e's eyes showed a strange light, and she brought some cakes.

After a while, Li Dongyang walked into the main hall: "What do you want to see me for?"

"I want to ask for a piece of calligraphy from you, the bigger the better." Yan Chengjin said.

In the capital, Li Dongyang's calligraphy is first-class.

Zeng Jian likes calligraphy with big characters, so asking Zhu Houzhao to give him a piece of calligraphy is also a way to please him.

Li Dongyang smiled proudly: "I already knew that you like my calligraphy, why do you come to ask for it now?"

"………… Yan Chengjin.

Li Dongyang took him to the study, spread out the paper and asked: "What do you want to write?"

Yan Chengjin thought for a while, and said: "Just write a "囍" character."

Li Dongyang didn't ask much, after writing a few characters on the paper to practice, he held his breath and concentrated, and wrote a big "囍" character on the paper.

The ink was still shining, so Yan Chengjin brought it out to Zhu Houzhao: "It's still warm, Your Highness, please send it to Lord Zeng."
