After a day's work, Li Fei soaked all of them in this new yard, teaching these novices how to make honeycomb coal again and again.

Fortunately, everyone's attitude is very correct, there is motivation for comparison, and in three aspects, a competitive situation has been faintly formed, and they all want to do their best, at least Li Fei will boast twice!

However, there are some things that have advantages, such as Qijia Village, which was originally born in farming, and they are familiar with rammed earth work, so their people are also the first to master it.

The second is Qu Tufeiying's subordinates, after all, although they used to fish and hunt for a living, but after arriving in Chang'an, they slowly changed to farming. There are many days of dealing with soil.

Those people in Yongning Fang, except for Chen Hu, who mastered it first, everyone else was the last to master it.

By this time, it was already dark.

Li Fei's voice was already dumb.

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

He didn't notice that Li Ziyan was in the courtyard gate, on the edge of the shadow wall, and watched for a long time before leaving quietly.

But what if you just know?

Give up this teaching to play with her?

Li Fei really didn't have this in mind.

At the moment, the most important thing is to get rich together with these three people, and at the same time make a name for yourself!

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, there were only twenty of them on each side, and Carpenter Li and his apprentices were rushing to do it.

If the mold is not enough, it is necessary to pick those who are clever and quick to learn, and others are also learning.

This is also a situation of competition, and we cannot engage in a big pot of rice.

In terms of details, Li Fei only mentioned a general direction, and these people who were selected to be the leaders were not all human spirits, at least they were all people who had brains and could think, and naturally knew how to make these details more perfect!

Li Fei still has his own business!

He soon went to the horse blacksmith.

"Master Ma, how's the stove going?"

Seeing that the horse blacksmith was still knocking on the piece of iron, Li Fei asked.

"It's hard to get." The blacksmith Ma rarely stopped, "This stove needs the iron sheet you said...... But this thing is too cumbersome to knock! Although you don't use a lot of each stove, if you use a large amount, it is not something that can be completed in a day or two! What's more, there are so many iron materials I can buy, and it is impossible to make all of them into iron stoves! ”

Li Fei understands this truth.

In these years, the hydraulic press has not yet appeared, and if you want to press the iron into an iron sheet, you have to knock it one at a time, and the efficiency is really very low!

The output of iron has always been controlled in the hands of the imperial court, and the private iron trade is already limited, and it is not easy to want more iron!

Li Fei suddenly thought of a possibility:

"Master Ma, do you think this is feasible...... For example, if the freshly burned red iron is relatively soft! At this time, use a big stone grinder to directly grind this iron a few more times, you can grind it thin, and then knock it into an iron sheet, is it easier? ”

Blacksmith Ma's eyes lit up:

"Huh...... That's a great idea, give it a try! ”

Li Feile, does this mean that you can pick up a handful of wool again?

Li Fei immediately asked:

"Then Master Ma, do you have anyone familiar with the ironmaking side?"

Blacksmith Ma nodded and said honestly:

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

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

"Isn't it...... That eldest grandson, and that Li family? ”

Blacksmith Ma nodded and said, "It's all official businessmen - ironmaking is an official camp." ”

"Can you introduce me? I can talk to them! ”

The horse blacksmith thought for a moment and said:

"I know a person who is in charge of an iron-making furnace, whether it is an official or an official, this person is very obsessed with iron-making technology, and should be interested in what you are talking about!"

Li Feile, as long as you find people and want to convince them, especially tech nerds, it should be a very simple thing!

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

The person introduced by Blacksmith Ma is called Wei Yinglong, and he is the Wei family - the Wei family with the surname Wuwang, that is, the Wei family that Li Fei offended.

However, Li Fei can be sure that this Wei Yinglong is a real technical nerd - when he heard his name, his expression did not even change, and his attention was more focused on the "creativity" that Blacksmith Ma said.

There are only two possibilities - or, Wei Yinglong has an opinion on the Wei family, so Li Fei indirectly made the Wei family suffer a loss, and he likes to hear it; Or, Wei Yinglong doesn't pay attention to the affairs of the Wei family at all, and only cares about his favorite technology, while Li Fei is more inclined to the latter.

"Ironskin? What's the use of asking for so many iron sheets? As soon as he heard that the new technology was mainly used to make iron sheets, Wei Yinglong lost interest, "Now, our army is clearing out the enemy troops on the border, and we need more weapons and better weapons, as for iron sheets, they are not very useful!" ”

Li Fei saw that this person was not interested, and he wanted to leave, and immediately became anxious, if he couldn't get this person, wouldn't it be difficult to get the stove done, he hurriedly said:

"How can it be of little use? Iron sheet is used well, it is a bit of an exaggeration to say that it will change the situation of the battle, but it is still possible to improve the survival chances of the warriors! ”

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

"I haven't consulted ...... yet"

"My name is Li Fei!" Li Fei looked depressed, daring to be attracted to the introduction of the blacksmith Ma just now, this Wei Yinglong didn't listen to it at all!

"Li Gongzi, please speak!"

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

"This ...... Feasible! Wei Yinglong's eyes lit up, but then he retorted: "I, the Tang Dynasty, are fighting in all directions, focusing on attack, and shielding ...... Not much use......"

Actually, it can't be.

However, Li Fei understood that the chips he threw were not enough, but he had already thought of another point, and said with a smile:

"The iron sheet is forged into iron armor leaves, or the half-body armor formed in one piece, which must be feasible for cavalry and soldiers to protect the opponent's crossbow arrows!"

Of course, this is possible, but there is still no hydraulic press, and it is still difficult to forge this thing!

Of course, it's okay to have a blacksmith beat.

In fact, the current iron armor itself is like this.

It's just that if the production of iron sheet increases, the yield of nail leaves will also increase, which is a good thing!

Although Wei Yinglong knew that what Li Fei said was a bit like a cliché, he immediately laughed when he explained the causal relationship:

"Li Gongzi really understands people! So without asking, how can this iron sheet be easier to produce? ”
