What Qin Feng didn't expect was that two hours later, Li Shimin and the princes of Zhongguo came to Qinzhuang on horseback.

"Qin Feng, Your Majesty is here!" Qin Huaiyu ran to Qin Feng's side and said to Qin Feng, when Qin Feng heard this, he put down his horn and walked towards the outside of Qin Village. Halfway through, I met Li Shimin, Qin Qiong and others.

"Minister Qin Feng greets Your Majesty!"

"Flat, quick, take me to see your ironworks!" Li Shimin hurriedly said to Qin Feng.

"Your Majesty, please!" Qin Feng took Li Shimin and others to the blast furnace, looking at the molten iron left at the blast furnace mouth, Li Shimin, Qin Qiong and others were very excited.

"Qin Feng, is this just one day's output?"

"Back to Your Majesty, yes, such a blast furnace can produce about two thousand catties of iron a day!" Qin Feng respectfully returned.

"Good, good! I'm looking! Li Shimin said with a laugh.

Several people watched by the blast furnace, while Qin Feng followed Li Shimin's side to explain the role of coke and limestone. Everyone sighed when they heard this. I walked around and returned to the pit where the molten iron was kept.

"Wind boy, this molten iron is iron when it's cool, isn't it?" The eldest grandson Wuji asked at Qin Feng.

"Uncle Hui, yes!" Qin Feng replied with a smile.

"That uncle has a question for you!" The eldest grandson Wuji touched his beard and asked Qin Feng with a smile.

"What's the problem?" Qin Feng was puzzled, this iron smelting is no problem.

"All the molten iron you've forged today has flowed up here, isn't it?" The eldest grandson Wuji said to Qin Feng slightly.

"yes!" Qin Feng nodded.

As soon as the others heard what Eldest Sun Wuji asked, they instantly understood something, sighed, and in the gloating eyes of Li Shimin and others, Eldest Sun Wuji asked Qin Feng: "Have you ever considered such a big piece of iron, making it like this?" How do you forge it when it's finished? ”

How do I take it out? Take it directly... , it seems that I really forgot about this stubble. You must know that this piece of iron weighs more than 2,000 catties, and it can't be taken out with the current manpower and material resources, and even if it is taken out, there is no good cutting method now. So, this time such a large piece of iron camel is placed here, it is a waste.

Qin Feng was embarrassed, while Li Shimin and the others laughed beside him, and even the villagers who were working on the side couldn't help laughing.

Fortunately, it is only the experimental stage now, and Li Shimin has also seen it today, and it is not a big deal that it can be changed when the furnace is built in the mine in the future.

"Your Majesty, since you have finished reading it, then I will stop working here, and the province will continue to refine and waste ore, and the minister has not prepared a suitable mold, so I can only leave it in this hole!" Qin Feng said to Li Shimin with an embarrassed expression.

"Stop!" Li Shimin said with a smile: "Qin Feng, I didn't expect that you, a smart person, would make such a mistake, it's really funny!" ”

The others couldn't stop laughing, and finally saw Qin Feng when he was embarrassed.

"Your Majesty, uncles, don't laugh at me! Everyone, please move to the village, it's too hot here, and I'll go back and report to you after the arrangement is made! Qin Feng stood in the distance, embarrassed, if there was a crack in the ground, he was afraid that he would drill directly into it, so he had to change the topic.

"Let's go!" Li Shimin took Qin Qiong and the others towards Qinzhuang, while Qin Feng stayed where he was, picked up the copper horn, and began to clean up the aftermath.

Half an hour later, the blast furnace gradually went out, and many farmers were paralyzed on the ground, and it is true that the weather is hot now, and the temperature next to the blast furnace is no longer appropriate.

Qin Feng shouted to Cheng Chumo Qin Huaiyu to return to Qinzhuang, found Steward Zeng, and asked Steward Zeng to bring ice cubes to each Zhuang household to send some to cool off. After arranging the housekeeper, the three of them went to the front hall to find Li Shimin and others.

When they came to the door of the front hall, Qin Feng and the three of them heard the sound of Li Shimin and others laughing in the front hall. The three entered the antechamber and saluted the crowd.

"Your Majesty!"

"Get up! Qin Feng, just now I was still thinking about what I want to reward you this time, and you came, so tell me, what do you want? Li Shimin said to Qin Feng with a smile.

"Your Majesty, the iron-making matter is not completely completed, and it is not too late to reward meritorious deeds after it is completed!" Qin Feng bowed and replied.

"Oh? Isn't that iron already smelted? We've all seen it, how? What else? Li Shimin asked puzzled.

"Your Majesty, there are three kinds of iron, pig iron, wrought iron, and steel! Pig iron is hard but brittle, making it difficult to continue forging again, while wrought iron is softer but easily deformed, while steel has two advantages of pig iron wrought iron, which can be forged again and is not easy to break. This is determined by the amount of carbon contained in the iron. Qin Feng explained to Li Shimin.

"Then you mean that the iron produced today is pig iron?" Li Shimin asked.

"Yes, Your Majesty, it will take some time to make steel, and some experiments will be required!" Qin Feng said.

Li Shimin nodded, and said to Qin Feng: "I believe that your kid has a way, and this matter will be handed over to you, I am waiting for your good news!" ”

"Your Majesty!" Qin Feng replied.

"Alright, let's get someone to prepare food and drinks, I'll be here to eat today! I'm going to have a drink with you kid! Li Shimin said to Qin Feng.

"Your Majesty!" Qin Feng was ordered to go out to arrange the preparation of wine and food.

Although Qin Feng is the inventor of liquor, it does not mean that Qin Feng is very drinkable, and he was drunk and carried back to the small courtyard early, and Li Shimin left with everyone to go back to Chang'an, and handed over the iron ore near Chang'an to Qin Feng before leaving, and will send someone to bring Qin Feng over tomorrow. And the Zuowei token was still in Qin Feng's hand, and he didn't take it back, so he took a piece with him, one to block the news, and the other to protect their safety.

On the second day, Qin Feng was woken up by Qin Huaiyu, and the people sent by Li Shimin arrived. Qin Feng got up helplessly, the hangover headache did not change at all, washed his face, ate, let people set up the ox cart, gathered the households who followed him yesterday to make iron, and brought more than a dozen craftsmen from Qinzhuang, leaving hundreds of left guards to guard Qinzhuang, and walked towards the outside of Qinzhuang with the rest of the people.

Qin Feng got into the ox cart and fell asleep again, and when Qin Feng woke up again, it was already afternoon, they had already arrived, and everyone was busy setting up tents.

"Fengzi, you're awake, tell me, what are you going to do?" Qin Huaiyu and Cheng Chumo sat on the side, watched Qin Feng sit up, and asked Qin Feng.

"What time is it?" Qin Feng rubbed his swollen head and said to the two.

"It's time for Shen!" Cheng Chumo said.

"Why don't you make a fart, help set up a tent, open a fire and cook, and talk about it tomorrow." Qin Feng said angrily to the two of them, seeing the situation at the scene, Qin Feng guessed that they should have just arrived.
