Rebirth of Lu Bu, the tyrant of the Three Kingdoms

Chapter 132, Bellows, Double Liquid Quenching Method (14)

Lu Bu said, "It's really not easy, but it's not impossible to improve, this Nine Ring Saber is considered top-notch in terms of the technology it's made of.

However, the heat is not enough, resulting in too many impurities in the blade, which cannot be regarded as the best quality, if the impurities in the blade can be removed, this precious sword will definitely be upgraded to another level."

Cao Ji snorted softly, "It's easy to say, but the heat is so easy to control, I installed eight exhaust fans when I built this Nine Ring Knife.

It took about half a month to forge a nine-ring knife, if Huang Zu hadn't been so deceitful and forcibly took the nine-ring knife, how could I have given it to him."

Lu Bu nodded, and looked at the devices in the blacksmith shop. It was indeed not that easy to increase the heat.

Lu Bu thought carefully for a while according to the environment of the scene, and he could make a bellows on the stove.

Open the movable wooden box by hand, and the air will fill the leather of the bellows with air through the air inlet, and then pull the body to press out the air inside, and the air can enter the melting furnace through the air duct to make the fire vigorous .

Can greatly improve the quality of the flame.

However, there should be no such thing as a bellows in the Han Dynasty.

Seeing a lot of wood piled up in the nearby shed, Lu Bu immediately walked over and said to Dian Wei, "Tiger, come and help me."

Combining the memories of the previous life to make the bellows, a total of three wooden rings, two round plates, and outer leather.

Pull the skin apart, the air enters the bag through the intake valve, compresses the bag, and the air in the bag enters the air duct through the exhaust valve, and then enters the smelting furnace.

It is very simple to make, but he can play a very good role.

Cao Ji stood by the whole time, watching Lu Bu make a bellows with his own hands.

Lu Bu wiped the sweat from his forehead, and then installed the bellows on the stove.

Cao Ji had a puzzled look on his face, "What is this?"

Lu Bu pointed to the bellows, "You will know if you try it."

Cao Ji dubiously walked over and pulled the rough bellows.

Two thick and powerful arms exerted their strength fiercely.

"Bang dang."

The bellows immediately fell from the stove.

A black line appeared between Lu Bu's brows, "I'm sorry, although this thing is ready, but I'm not very good at installing it, or let's try again."

Cao Ji shook his head lightly, "Oh, seeing how hard you have been making this thing just now, leave the installation to me, although I don't know what the use of this thing is."

Cao Ji lifted the heavy bellows from the ground.

He exhaled softly, "Hey, this thing is a bit heavy."

Dian Wei hurried over to help, lifting the bellows with one hand.

Cao Ji glanced at Dian Wei, secretly surprised at how strong this man is.

Then he skillfully reinstalled the bellows on the stove.

Dian Wei couldn't wait to bend down and pull the bellows lever, "This thing is not light."

As he spoke, he suddenly exerted force with his hands, pulled out the lever, and then pushed it in hard.

The impact of airflow is generated in the bellows, and it is sprayed into the furnace from the mouth of the bag.

The charcoal fire burst into flames with a "huh", dancing with blue flames.

"It's hot!"

Cao Ji couldn't help shouting.

He has been a blacksmith all his life, and he has made all kinds of weapons, so he is naturally very familiar with fire control.

I didn't expect that the heavy wooden box made by Lu Bu would have such a function.

After thinking about it carefully, it is not difficult to understand that the principle of the airbags they usually use is the same, but the effect of the bellows after processing is more than ten times that of the airbags.

Looking at the dancing flames, Cao Ji quickly added some charcoal to the stove.

Dian Wei's two thick arms kept pulling the bellows pole, making a "whoosh" sound.

Seeing that the charcoal fire was burning vigorously, Cao Ji immediately put the nine-ring sword into the charcoal fire.

Shouted, "Man, don't stop, keep pulling the bellows".

Dian Wei exhaled lightly, and then quickly pulled the bellows, one pull and one push, and the red flame kept jumping under Dian Wei's push.

Cao Ji was overjoyed, looked at the dancing flames, and then stroked the heavy bellows, his eyes shone with red light, and the blue flames kept dancing in his eyes.

"Little brother, what is the name of this thing? With this thing, the problem of not enough heat can be greatly improved," Cao Ji said.

Lu Bu patted the dust off his hands, "This thing is called a bellows."

Cao Ji nodded slightly, "The appearance of this thing is simply the gospel of blacksmiths."

At this time, Cao Ji took out the fiery red knife embryo with iron tongs, put it on the cutting board, and continuously forged and beat it.

Every time he struck, Cao Ji exerted all his strength, and saw sparks flying, the knife embryo gradually formed, and the temperature also slowly dropped.When the knife blank was almost dark red, Cao Ji stopped forging, clamped the knife blank, and prepared to put it into the water.

Lu Bu shouted, "Wait a moment".

Then he quickly brought over the horse urine that had just been prepared, "Put it here for quenching."

Cao Ji paused, and put it in with some doubts.

It makes a "sizzling" sound and emits a pungent and foul smell.

Cao Ji frowned, "What is this, it's so pungent."

"This is horse urine, and it is a peculiar double-liquid quenching method. First, the blade is quenched in horse urine.

Then put it into the grease tank I just prepared for secondary quenching, which can ensure the hardness of the knife blank, prevent cracking and deformation at the same time, and make it have a certain toughness.”

"There is such a saying?" Cao Ji said in shock.

"You will know if you try it."

Speaking of it, this is really not a great invention, but for this era, it undoubtedly has great significance.

Don't look at these two simple liquids, but also need to consider the skill and experience of the craftsman.There is no equipment for temperature measurement and temperature control, and the operation is performed entirely by feeling.

If it is done by an inexperienced person, even the double liquid quenching method is useless.

Cao Ji polished it again, and raised the Jiuhuan Dao with one hand.

With his right hand stroking the blade, a look of shock appeared on his face.

Others might not be able to see the change, but Cao Ji made his living by making ironware, so he could see the difference clearly at a glance.

Lu Bu also stood aside thinking, there is no coal yet, most of them use charcoal, if coal is used, the fire should be more intense than it is now.

Cao Ji put down the Jiuhuan Saber, put away his arrogance before, and immediately walked towards Lu Bu, with a rough appearance, revealing a wildness.

"I don't know who this brother is. The bellows you just created and the double-liquid quenching method are really amazing. They can actually improve the quality of the Jiuhuan Dao to another level," Cao Ji said.

With a calm face, Lu Bu returned a gift to Cao Ji. He was just admiring Cao Ji's ability to forge swords. If he could persuade him to go with him, that would be the best. If he didn't want to, Lu Bu would not force it.

"I'm Lu Bu, governor of Bingzhou. He heard about Brother Cao's ability to forge swords, so he came here to pay a visit," Lu Bu said.

Cao Ji's expression was slightly startled. Although there were countless high-ranking officials and merchants who came here for fame, most of them were leading soldiers and leading generals and pretending to be noble.

It is really the first one who is as approachable and unassuming as Lu Bu.

　Last weekend, a few fellow villagers got together and drank a bit too much. I made it up today. The fourth watch, if I have time, the fifth watch. Please collect, recommend, and give me a small reward. Thank you.
