Cao Ji did not dare to stop, and continued to drill the drill pipe and sang loudly.
"Peng'er, I strongly recommend it!"
As Cao Ji shouted, Cao Peng pulled out the pole with all his strength, and then pushed it away with all his strength. In the furnace, a ball of flame suddenly rose up, instantly igniting the drilling board. Cao Ji quickly let go and pushed Cao Peng to the
Next to him, he shouted loudly: "Peng'er, add charcoal, add charcoal!"
Wang Meng and his son brought in two buckets of charcoal from outside the shed.
Under Cao Ji's guidance, Cao Peng put the food into the furnace very rhythmically.
The furnace must be filled and the temperature of the furnace maintained. When the charcoal fire appeared, Cao Ji released the lever and signaled Cao Peng to step back.
In this short time, Cao Peng was exhausted and dripping with sweat.
Not only physically tired, but also psychologically tired... This ceremony to welcome the coming of the God of Fire created an extremely solemn environment. Working in this environment and exerting one's strength is equal to normal work.
Use three points, four points... How can Cao Peng not get tired?
"The God of Fire is coming!"
The charcoal fire made Cao Ji's face turn red, and a bright smile appeared on his honest face.
"Dad, is this the end? When can we hammer?"
"Where does it end?"
Cao Ji smiled and said: "This is just the beginning. We have to stare at the fire here. When will the flame change color, when can we start the first hammer blow? Peng'er, I have told you a long time ago that blacksmithing is a
It's a very hard job. Just starting the furnace, from now on, we can't take a step away from each other. It won't be truly over until the first hammer falls. Take a break and recharge!
Whether the first blow is good or not is of great importance."
Cao Peng couldn't help but swallowed his saliva!
Oh my gosh, after struggling for a long time, is this the beginning?
"Afu, do your best, I'm waiting for the sword you made with your own hands."
Wang Mai laughed heartlessly, and Cao Peng was so angry that he shouted angrily: "Get out!"
In the blink of an eye, Wang Mai disappeared...
Wang Meng was on the side, helping and chatting with Cao Ji.
The temperature in the shed gradually increased. Cao Peng wiped the sweat from his head and sat down aside. With three hundred and sixty lines, he would be the number one scholar... It seems that blacksmithing is really a technical job. For an ordinary craftsman like my father.
, they have to put in so much effort. I guess those great craftsmen and masters will have to work even harder. I really don’t know where the legendary sword-making masters came from?
Cao Peng was thinking while watching Cao Ji busy.
In this way, the day gradually passed without realizing it.
As the sky began to darken, it suddenly started to snow heavily.
Deng Ji also came back and helped outside the shed.
"Start melting the iron."
Cao Ji gave an order, and Wang Meng immediately picked up a wooden bucket full of broken iron tools and poured them in. These broken iron tools were all collected before. In fact, they are of no great use. They are mainly used to prepare the ground for the first hammer blow.
That's it. Once the furnace is turned on, you can't rest. When the iron in the furnace began to melt together, Cao Ji waved to Cao Peng and asked him to get ready to hammer.
Using pliers to cut out a workpiece, Cao Peng stepped forward with a special hammer.
This hammer, weighing eighteen kilograms, was specially prepared by Cao Ji for Cao Peng. Cao Peng took a deep breath, clamped the workpiece, and opened his stance.
When he exerted force with one arm, he roared loudly, his anger left his Dantian, and the wheel hammer hit him.
clang……
There was a crisp sound and sparks flew everywhere.
"The golden flowers bloom and the God of Fire returns to the palace!"
Cao Ji was overjoyed and went out, rushed over, grabbed the pliers, and smashed the wheel hammer.
The hammer he used weighed sixty-eight kilograms, which was a full fifty kilograms heavier than Cao Peng's hammer. The force of the blow was naturally different, and the clanging sound was endless. In the light of the fire, Cao Ji's face showed a smile
With an excited smile and focused eyes, there is a unique charm...
The blow was made with almost all the strength of the body.
After Cao Peng retreated, he let out a long breath.
"Ok?"
"Haha, I didn't mess it up."
"That's good, that's good!"
Deng Ji was in the shed and saw a thrilling scene.
How could he have imagined that a hammer could achieve such a momentum?
As Cao Ji rotated the sledgehammer, the muscles on his bare arms beat rhythmically. It wasn't just the strength of his arms, in fact Cao Ji's whole body was moving, including his mind.
"Afu, does the method you mentioned really work?"
Wang Meng asked softly, and Cao Peng smiled and said, "You'll know if it works or not if you try it?"
As early as the Warring States Period, our ancestors invented the quenching technology. However, for a long time, from the Warring States Period to the end of the Eastern Han Dynasty, no matter how people quenched, they could not get rid of using water as the cooling medium for quenching. During the Eastern Han Dynasty, people realized that,
Quenching with different water can produce knives with different properties. Therefore, water identification has become a required course for weapon craftsmen.
It's just that this ability to distinguish water requires talent.
There may not be one out of a hundred people, so master craftsmen become extremely scarce.
Pu Yuan, a knife-making expert in the late Three Kingdoms period, possessed such a technique. Unfortunately, there are very few people who can master this technique.
Cao Ji didn't know how to distinguish water, so he couldn't become a great craftsman.
However, Cao Peng gave him an idea: first quench it with animal urine, and then quench it with animal fat, which might have a miraculous effect.
Ask him how he knows this?
Cao Peng said: "The old alchemist told me."
In my heart, I don't know how grateful I am to that mysterious old alchemist. If it weren't for him, Cao Peng really didn't know how to explain it.
In people's minds, alchemists are people with great supernatural powers, and may even be gods.
Since it was said by a god, it must have a special effect. Cao Ji naturally believed it and expressed his willingness to try it without hesitation.
If Cao Peng's method can really solve the water problem, then Cao Ji can break through a threshold and take a big step forward.
In the shed, a pool of horse urine and a pool of lard were prepared. Horse urine does not cost money, and the Cao family's three horses are almost enough.
But this lard... really cost a lot of money.
If he failed, Cao Peng would inevitably be blamed.
"Dad, I'm tired. I'm going to rest first..."
"Okay, you go and have a rest first."
Cao Peng was naturally full of confidence, because he told Cao Ji about the double-liquid quenching method, which was confirmed by later generations. During the Southern and Northern Dynasties, Qi Guanhuaiwen, a master of military casting, invented this double-liquid quenching method and built the tripod.
The famous Su Tiedao. It was precisely because of the emergence of this double liquid quenching method that the later Heng Dao and Mo Dao came into being... Cao Peng believed that Cao Ji would be able to take a big step forward after solving the quenching problem. However,
, he did not tell Cao Jisu how to make the iron sword, because he felt that it was too early.
Back in his room, Cao Peng seemed to have collapsed. He sat down and never wanted to move again.
Finally solved a problem!
If dad can make a good knife using the double liquid quenching method, he will be able to stand firm no matter who he works for in the future.
This is a great achievement...
The quenching problem is solved, and all that remains is to increase the furnace temperature and solve the problem of the bellows.
Cao Peng took a breath, stood up and walked to the desk.
Huh?
Where are my drawings?
He was surprised to find that the bellows drawing he had drawn before was missing...
Cao Peng shivered and rummaged through the cabinets in the house, but he couldn't find those drawings. Don't think they were taken away!
He ignored his fatigue and rushed out of the room like the wind.
"Mom, who came into my room today?"
Zhang and Cao Nan were preparing dinner when they heard Cao Peng's roar and were stunned.
"I didn't go in... Nan, did you go in?"
Cao Nan shook his head, "I've never entered Ah Fu's room? Ah Fu, what happened? Why do you look so ugly... Hey, where are you going?"
Before she could finish speaking, Cao Peng turned around and left.
Normally no one would enter his room...
Except for Zhang and Cao Nan who helped him clean up the room, neither Cao Ji nor Deng Ji, including Wang Meng, would go in.
Wang Mai comes in and out often, but he stayed with me all day today.
Calm down, be sure to calm down!
Cao Peng kept reminding himself and tried hard to recall.
Last night, I studied the drawings... Then I felt tired and went to sleep! But before going to bed, I... By the way, I stuffed the drawings into my leather pocket.
Where is my leather pocket?
Cao Peng is really anxious...
"Brother Hutou, have you seen my black leather pocket?"
Wang Mai said: "Is it the leather bag you took away this morning?"
"yes!"
"Didn't you bring it back?"
I remembered!
When I was taking a break from practicing, I took off my leather bag and placed it under the peach tree on the river beach. I was in such a hurry that I forgot about it.
If it's broken, don't let anyone take it away...
That leather pocket wasn't worth much. At best, it was because his mother sewed it for him, so it was of commemorative significance. But the drawings inside...
A layer of fine beads of sweat suddenly appeared on Cao Peng's forehead.
