In one day, Li Fei spent all sleeping in this new yard, teaching these novices how to make honeycomb coal again and again.

Fortunately, everyone's attitude is very positive, and there is motivation when there is comparison. In three aspects, a competitive situation has formed a vague trend. They all want to do their best, so Li Fei should praise it at least twice!

However, some things have advantages. For example, Qijia Village was originally a farm worker, and they were familiar with rammed earth work, so their people were the first to master them.

The second is Qu Tufeiying's subordinates. After all, although they used to make a living by fishing and hunting, they gradually changed to farming after arriving in Chang'an. They had a lot of life to deal with soil.

Except for Chen Hu who mastered the people in Yongningfang, everyone else only mastered them in the end.

And by this time, the sky was already dark.

Li Fei's voice was hoarse.

But he was very happy - at least the people present were able to make qualified honeycomb coal - although there were still defective products, not many.

He didn't notice that Li Ziyan was in the courtyard gate and beside the screen wall. She looked at it for a long time before leaving quietly.

But what if you know?

Give up this teaching and go play with her?

Li Fei really doesn't have the intention.

At present, the most important thing is to bring people from these three aspects to become rich together and at the same time make your name known!

The next day, Li Fei asked people from all walks of life to send the first batch of molds - the molds were not made so quickly, with only twenty of them on each side, and Carpenter Li and his apprentices were rushing to make them.

If the mold is not enough, you have to choose those smart, learn quickly, and others will help you, and at the same time, you will also learn.

This is also a competitive situation, and you cannot make big pot meals.

Regarding details, Li Fei only mentioned a general direction. The people who chose the leader were not all human beings, but at least they were all people with a mind and thoughtful mind. Naturally, they knew how to make these details more perfect!

Li Fei still has his own affairs!

He quickly went to find Ma Blacksmith.

"Master Ma, how is the stove going?"

Seeing that Ma Blacksmith was still knocking on the iron block, Li Fei asked.

"It's not easy to do." Ma Blacksmith stopped his hand rarely, "This stove needs the iron sheet you mentioned... But this thing is too troublesome to knock! Although you don't use much for each stove, your amount is large, so it's not something that can be completed in a day or two! Besides, there is only so much iron material I can buy, and it's impossible to make it into an iron stove!"

Li Fei understands this truth.

Nowadays, the hydraulic press has not appeared yet. If you want to press the iron block into iron sheet, you have to knock it one by one. The efficiency is really very low!

The iron production has always been controlled by the court. The private iron trading is already limited, so it is not easy to want more iron!

Li Fei suddenly thought of a possibility:

"Master Ma, do you think this is feasible or not... For example, the red iron block that has just been burned should be relatively soft! At this time, use a big stone mill and directly crush the iron block a few more times to make it thinner. Will it be easier to knock it into iron sheets?"

The blacksmith's eyes lit up:

"Huh... This is a very good idea, you can try it!"

Li Feile is over. Does this mean that he can get another handful of wool?

Li Fei immediately asked:

"Master Ma, are there anyone you know about the iron smelting side?"

Ma Blacksmith nodded and said honestly:

"At present, the largest iron merchants in Chang'an City are controlled by two companies, one is the Changsun clan and the other is the Li clan."

Li Fei seemed to have heard of these two companies, pointed upwards and asked guessingly:

"Are it... that Changsun and the Li family?"

Ma Blacksmith nodded and said, "It's all official businessmen - iron smelting is the official business."

"Then can you introduce it? I can communicate with them!"

Ma Blacksmith thought for a while and said:

"I know a person who manages iron smelting furnaces, whether they are officials or officials. This person is very obsessed with iron smelting technology and should be interested in what you said!"

Li Feile is so happy that it should be a very simple thing to find someone and want to convince them, especially the technician!

However, soon Li Fei knew that he was thinking too simple!

The person Ma Blacksmith introduced was Wei Yinglong, who was a member of the Wei family - the Wei family with the five and seven surnames, which was the Wei family that Li Fei offended.

However, Li Fei was sure that Wei Yinglong was a real technician. When he heard his name, his expression did not change much, and his attention was more focused on the "creative" that Ma Blacksmith mentioned.

There are only two possibilities - either, Wei Yinglong had an objection to the Wei family, so Li Fei indirectly caused the Wei family to suffer a loss, which he liked; or Wei Yinglong did not pay attention to the affairs of the Wei family at all, but only cared about his favorite technology, while Li Fei was more inclined to the latter.

"Iron? What's the use of so much iron?" Wei Yinglong lost interest when he heard that the new technology was mainly used for iron. "Now, our army is clearing out the enemy on the border and needs more weapons and better weapons. As for iron, it's not very useful!"

When Li Fei saw that this person was not interested and was about to leave, he immediately became anxious. If he couldn't handle this person, wouldn't it be difficult to make the stove? He quickly said:

"How could it be useless? If the iron sheet is used well, it is a bit exaggerated to say that changing the situation of the war is a bit of a big deal, but it is still possible to increase the chances of the warriors' survival!"

As soon as it heard that it was related to the practicality of war, Wei Yinglong immediately stopped and bowed to Li Fei:

"Not yet asked..."

"My name is Li Fei!" Li Fei looked depressed. It turned out that Wei Yinglong didn't listen to the introduction of Ma Blacksmith just now!

"Mr. Li, please speak!"

"Iron wraps wood, made into a shield, has high defense, and is lighter than a pure iron shield, natural and practical!"

"This... works!" Wei Yinglong's eyes lit up, but he immediately refuted: "I fought in all directions in the Tang Dynasty, focusing on attack, and shield... are not very useful..."

Actually it is impossible.

However, Li Fei understood that he didn't throw enough chips, but he had thought of another point long ago and said with a smile:

"Forging iron into iron armor leaves, or half-body armor formed in one piece, it is inevitable that for the cavalry, the soldiers will protect the opponent's crossbow arrows!"

Of course this is feasible, but now there is still difficulty in forging this thing without a water press!

Of course, it is OK to let the blacksmith beat him.

In fact, the current iron armor tools are like this.

However, if the yield of iron sheet increases, the yield of tart leaves will also increase, which is a good thing!

Although Wei Yinglong knew that Li Fei was a bit cliché, he immediately laughed when he explained the cause and effect:
Chapter completed!
