In the next few days, Yan Bing basically maintained the frequency of practicing in the morning and building a sword-making workshop in the afternoon.
The senior brother and the fifteenth senior brother, besides practicing martial arts, have also become Yan Bing's right-hand assistants...and...apprentices...
When stacking furnace bricks, she used the gaps in the furnace bricks to teach them what "thermal expansion and contraction" are.
When making hand-operated sealing boxes, they were taught what the "piston principle" is.
While making coke in the kitchen, I explained to them what "dry roasting" is and what "temperature" is.
But unexpectedly, Lu Liang, who had always behaved like a fool, learned this knowledge faster and remembered it better.
But the senior brother taught him ten sentences, and he asked you nine questions, all kinds of tricks... Yan Bing was so angry that he stopped teaching for three days, and he stopped asking any more useless nonsense.
It took a full eleven days to complete a simple sword-making workshop.
As for the old man, he did nothing during these eleven days. He just sat in the courtyard drinking tea. Then, he looked forward to the stars and the moon every day, waiting for someone from the palace to come and collect his wine... but there was still no news.
Even little Vincent has not appeared again for more than ten days.
All these signs indicate that this business is going to be bad!
This also caused the old man's face to become longer and longer in the past ten days, his mood became worse and worse, and his temper became worse and worse.
Li Bing and his two senior brothers could only take turns trying to persuade him. They had millions of taels of banknotes at home, so why bother with a liquor seller?
And the old man's meaning is very clear. No matter how much money you have, you will always have nothing to gain. In the end, you will have to beat them up. Apart from spending money, no one can make money...
But when it comes to Fengchen and Lu Liang, they have no temper at all. Can Yan Bing tolerate this?
The furnace was about to be forged to make the sword today, and she could bear this tone to the end.
"Senior Brother! Fire! Fifteenth Senior Brother, turn on the bellows!" With Yan Bing's shout, the flames of the blast furnace were lit for the first time.
In order to test the safety of the newly built blast furnace, Yan Bing chose pig iron as the first test object.
Using the stacking method, iron ore and charcoal are stacked layer by layer. On top of each layer of charcoal is a layer of iron ore, and on top of the iron ore is another layer of charcoal. This is repeated until there are seven layers.
The maximum temperature of charcoal can also reach one thousand degrees. In this way, it can not only provide necessary materials for the subsequent "steel filling method", but also test the reliability of the blast furnace within a safe range.
When the ashes are burned out and the smoke dissipates, several pig iron blocks containing impurities are obtained from the furnace.
The blast furnace also survived the first test and the test was a complete success.
The next step is to directly challenge the steel filling method.
After smelting the pig iron into molten iron in a crucible, it is poured directly onto the wrought iron ingot, and then assisted by oxygen blowing, it is possible to produce steel ingots with up to standard carbon content in large quantities at one time.
The coke that was fired in advance will be put to use now. The temperature in the furnace at this time will reach a terrifying two thousand degrees. As long as the blast furnace can survive this level, it can completely prove the reliability of the blast furnace.
sex.
However, it was this crucial step that caused Yan Bing to be eliminated by her two "apprentices"...
The reason is very simple. If the furnace really explodes, they can guarantee that they will not be too seriously injured. But if the junior sister is injured because of this, then they may really die...
Because recently, various signs indicate that the old man's temper is getting more and more violent, and it is very likely that he will beat the two to death if he makes a mistake. They believe that this is not what the junior sister wants to see...
In the end, the two of them were so helpless that they almost knelt down while talking. Yan Bing could only return to the top obediently and wait for their good news.
When Yan Bing, who was anxiously waiting for the results, was about to collapse emotionally, two "black monkeys" jumped out of the secret room and grinned at her.
Yan Bing knew that it was done. In excitement, she pounced directly on the two "proud apprentices", causing the two straight men to blush. She didn't care, because it was so dangerous to explode the furnace.
No one knows it better than her, so for her, this is a life-and-death friendship, and she has to admit it.
Next, everything was on track. Under Yan Bing's guidance, the two "apprentices" quickly mastered all the processes of steelmaking, and with their superb fire-making and polishing techniques, they became two
, "The one who is better than the old is better than the old", graduate.
As time passed, more and more steel swords were forged. When all the materials piled in the backyard were exhausted, they began to count the number.
"Senior brother, I have one hundred and seventy-two here, what about you?" Lu Liang finished counting the two boxes in front of him and looked back at his senior brother and asked.
"I have one hundred and forty-four here, plus the two hundred and eleven from my junior sister's side, the total is..." Feng Chen narrated while doing mental calculations, but in the end he still couldn't figure it out, so he simply squatted on the ground.
, took the sword and made signs on the ground.
Yan Bing shook his head helplessly, and then gave an accurate number: "527, stop scratching, the floor tiles will irritate you."
"More than five hundred!? Even if it's 10,000 taels per hand, this is more than five million taels of silver!" Lu Liang looked excited.
The senior brother looked at Lu Liang and rolled his eyes: "Why are you so obsessed with money!? Why don't you learn something good from your master? Why don't you learn to be greedy for money?"
However, before he finished speaking, he suddenly heard the old man's long voice behind him.
"What did he learn from me? Come, Fengchen, and explain it to me in detail..."
Feng Chen was stunned for a moment, then looked behind him tremblingly, and saw his master standing at the door of the secret room, picking his ears and staring at him with cold eyes.
Immediately, I was so frightened that my hair stood on end. I didn't dare to say a word. I just instinctively leaned towards the secret door behind me, with a posture of "I'll run away if you dare to come over."
After all, in his opinion, the old man was not an ordinary "small-minded" person, but rather a very small-minded person.
But to everyone's surprise, the old man smiled again and said, "That's all, I'm in a good mood today, so I won't argue with you."
Then, he blew his little finger that he had just picked out his ears, looked at Yan Bing and continued: "Qihua, come up here, I have something to ask you." After saying that, he ignored Feng Chen, who was about to pee with fear.
He jumped out directly.
Seeing that the old man had just left like this, the three people looked at each other with expressions of disbelief.
In the end, it was the senior brother who spoke first, and said with a pleading face to Yan Bing: "Junior sister, my own junior sister! Come up later and help senior brother have a sound test, so I know if I need to go out and hide for two days before coming back.
"
"Don't worry, senior brother, no matter what the outcome is, junior sister will inform you in advance." Yan Bing answered with a serious face, turned around and went out.
Lu Liang on the side suddenly stopped her, then lowered his head and hesitated for a moment, and then said seriously: "After you go up, junior sister, you... must inquire more carefully... If..., you need to arrange it in advance.
If you want to buy a coffin..., you tell me and I will do it..."
When Yan Bing heard this, he laughed secretly, but he quickly held it back and put on a sad and indignant expression. He looked at Lu Liang and said emotionally: "Don't worry...Fifteenth Senior Brother, my little sister knows..."
"That's enough for you two! If you scare me again, I'll wet my pants for you too!!"
At the same time, Wen Pei, who was serving the fourth prince's meal, suddenly sneezed...
