The next morning, Lu Ya stretched his waist and came to the training ground, and called Xiong Daxiong Er, who was exercising, from the side. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info carefully instructed the two of them to take a few slaves to ride to the market and then buy some poultry and livestock, the poultry and livestock brought back last time have been killed, this purchase is really regarded as a reserve, and finally Luya also instructed the two to see the situation of Boone and Johnson.

Xiong Daxiong Er executed the order very quickly, and after ten minutes, they each got on the car, and a few slaves fell behind the car and set off. After sending Xiong Da and Xiong Er away, Lu Ya came to the iron-making area slowly while gnawing on a rice ball with white flowers, and after finding the old man, he ate the rice ball in his hand in three or two bites, and began to study steelmaking with the old man Tie, this time Lu Ya told the old man that he only had a little inventory, and Lu Ya didn't know much, and he was not good at this, so it was better to tell the old man about it all as to whether it could succeed or how to experiment with him.

"Uncle, don't write about it yet, I have also heard of two ways to improve the quality of molten iron, and I will tell you both today. Ruya patted the old man with a charcoal pen in his hand.

"One is to sprinkle raw ore powder into the molten iron, and the other is to mix a certain proportion of toner powder into the water, as for when to mix, how much, I really don't know, uncle, you are pedantic, plus so love this trip, I believe you will be able to succeed. Lu Ya was very irresponsible, and after telling the old man what he knew, he patted him on the shoulder again, looking like I am optimistic about you.

"That's it?" the old man held the animal skin in his hand, looking a little dazed.

"Uncle, don't feel less, although these few sentences are really not many, they are indeed very detailed, and they contain the hard work of my predecessors. If you can succeed in the test, I guarantee that you can refine the steel that you have never seen in your life, and you will be famous in history from now on~ "Lu Ya is not bragging about the two brilliant essences of 'fried steel' and 'steel filling'.

"Also, it's the carbon content I told you last time, for example, the blade needs to be made of steel with a slightly higher carbon content and uniform carbon content, while the back of the knife needs steel with less carbon content and stronger toughness, and a single steel quality is not suitable for making a whole weapon. ”

The old man's comprehension ability is really strong, although he doesn't know exactly how the word carbon content comes from, but he can understand that this can be controlled by himself, and the most important thing he lacks is the spirit of experimentation, so after listening to it, he first wrote it down on the animal skin, and then he was already a little eager to try it on the spot.

"Don't be in a hurry to leave, do you still have an impression of the coke I told you last time," Lu Ya grabbed the old man and asked.

"There's an impression, what's wrong" The old man turned his head suspiciously.

"That's right, this kind of thing called coke, it's the most suitable for making iron, but if you always want to use it, you still need to make it yourself, I'm not very good at this, hehe" Lu Ya rubbed his nose.

"Oh, then you say, how to do it" The old man Tie was full of indifference, as the so-called a sheep is also driven, and a flock of sheep is also herded. Thinking about it, he has figured out Lu Ya's routine these days, but he doesn't know why, and he doesn't expect Lu Ya to say one, two, three.

"Ahem~ I don't know the specific method, I just know that the coal is heated to a temperature that can almost melt the iron ore in a confined space and then quickly extinguish it to cool down, as for how to get it, it still depends on you are old, hehe" Lu Ya shook his hand with a face.

"Finished again?"

"It's over!"

“····”

"Hehe, I'll take you to test the converter first."

Lu Ya grabbed the old man with a pensive face and came to the converter, which had completely dried and was lying quietly on the ground.

······

Half an hour later, the old man gave the order to "release the molten iron", and a slave opened the tap hole, and the hot molten iron flowed directly into the small converter connected below.

Streams of air poured out of the converter along the reserved air duct, and a large flame immediately rose from the entire furnace mouth, and in the following few minutes, the flames grew larger and larger, and when Lu Ya ordered the converter to be straightened, he threw some limestone into the furnace for refining lime, and when the iron old man asked why, Lu Ya couldn't tell why.

After a few more minutes, the flame at the furnace mouth gradually diminished until it disappeared, and only a cloud of air distorted by the high temperature came out of the entire furnace mouth.

After a while, gray-brown smoke suddenly rose from the furnace, and Lu Ya slapped his thigh and shouted "Stop, tapping"

Several abrasives were lined up in turn, but fortunately, this time it was only for the test that the converter was not large, and after pouring a few abrasives, there was no molten iron flowing out of the furnace, only slag remained. Ruya and the Iron Old Man immediately stared at the cooling abrasive.

A few minutes later, a silver-white spearhead blank appeared in front of everyone's eyes, the surface of the blank was smooth and glowing white, and a faint frosted feeling appeared when the fingers caressed it.

"This... This·· The dagger... It seems·· This·· Okay," the old man stroked the spearhead carefully, and began to speak incoherently again.

"Uncle, this is steel, we succeeded, and it seems that the quality of steel this time is better than that dagger. Ruya was also overjoyed in his heart.

"Oh my God, I didn't expect my old man iron to be able to witness the birth of this kind of steel in his lifetime, and die without regrets~" The old man finally calmed down his mind a little, and he was full of emotion.

"You~ not only see it, you can still do it in the future, but if you successfully test all the methods I said, then in the end, the steel you make will definitely be much stronger than this"

"Hehe, yes, yes, I want to hurry up and experiment, hahaha, I didn't expect ah, my iron old man can also refine this kind of top-grade steel, hahaha" After the iron old man finished speaking, he no longer paid attention to Lu Ya and got busy with himself.

In the next two days, Lu Ya began to be busy with the problem of winter heating, according to Lu Ya, since there is coal, how can everyone be able to burn the stove in winter, but the problem is that the furnace is all iron lumps, even if the quality of iron is not high, but the quantity needed is a lot, like the iron ore brought back last time, it is estimated that all of them are made into furnaces and are not shared, and gas poisoning is also a problem that Lu Ya needs to consider, he doesn't want to make a collective gas poisoning in order to get warm, then it will be more than worth the loss.

"The iron sheet is not yet made to this extent, it seems that it is more reliable to repair the fireplace" Lu Ya thought for a day before making up his mind.

Thinking of doing so, Ruya first went to the old man and asked for a few slaves, and when he came back, he began to teach them how to make simple adobe bricks.

Seeing these tall slaves squatting on the ground and living in the mud, Baruya really felt a little happy, and then felt that the slaves were indeed a very good labor force, which was not that Luya was in favor of slavery, and these slaves had not been abused, and they could have something to eat just because they were grateful for their work on weekdays, which was already very happy.

The honeycomb stove was made quickly, and nearly a thousand clay bricks were set aside in just one morning.

Lu Ya also asked these people to build several small brick kilns more than one person high outside the tribe, and burning bricks is also a technical job, which requires a lot of experience, so failure is also a matter of course.

It was impossible for Ruya to take care of these brick kilns all the time, so after asking around the tribe, Uncle Rip gladly accepted the honorable position of the head of the first brick factory of the Blackstone tribe, and began to supervise the production work on the same day.

Luya told Rip that burning bricks is a technical job, don't be afraid of failure, come less at a time, come more times, and feel the law to mass production.

Rip also said that if he couldn't burn Rua's standards, he would live next to the brick kiln and not go home.

Ruya nodded reassuringly after praising Rip's determination.

So from that afternoon onwards the slaves were never clean, some of them pulled coal back and forth, some kept pushing mills, some stirring clay. Some pressed bricks, and Rip leisurely found a rocking chair out of nowhere, and rocked it leisurely every day, getting up from time to time to supervise a few sentences, and occasionally going to the temporary hospital to flirt with Aunt Kama, and the days were very leisurely······

On the third day after the two left, the guards on the tribal watchtower spotted a convoy approaching here in the distance, and the guards who were still apprehensive after the last attack did not hesitate to ring the alarm bell beside them.

"Bell bell bell · · "

When the nervous crowd gathered to think that someone was attacking the tribe again, the guard in charge of the lookout shouted apologetically downward.

"It's not the enemy, it's Xiong Da and Xiong Er, hehe"
