Douba: I can upgrade everything infinitely

Chapter 191 Chapter 180 Nine We have all learned this in junior high school 【Subscription】

"Brother Feng, what's the matter with you, are you not feeling well?" Feng Wu murderously tempered his body, and his whole body had to endure not-so-slight pain, his complexion was slightly pale, and he was sweating.

As soon as he went out, Dong Wen saw it at a glance.

"If you feel unwell, then take a day off, and Dong Wu and I will teach you forging again." Dong Wen looked at Feng Wu's poor condition, although he was puzzled, logically speaking, with their cultivation base, all diseases should be cured, but Feng Wu looked quite weak.

"Could it be that something went wrong in the practice last night?" Dong Wen guessed in his heart.

"It's okay, it's not a big problem." Feng Wu shook his head to indicate that he had no problem, and said, "Let's go, let's start.

If we study one more day and help Senior Yueyang break through the grasp of the seventh-rank cauldron casting master, we will get one more point.

I'm so envious of the seventh-order medicinal cauldron Senior Yueyang promised me, I can't sleep. "

Feng Wuan praised him, and at the same time felt that his situation was much better.

Everything has an endurance.

After the first endurance, the feeling of pain in the next occurrence will plummet, and endurance gradually becomes a habit.

The pain was still at that level, but after persisting for about a quarter of an hour, Feng Wu felt that the feeling of murderous aura quenching his body was no longer so piercing.

Habit is a force more terrifying than perseverance.

Seeing that Feng Wu still persisted, Dong Wen didn't persuade him anymore.

Bring Feng Wu to the forging room, forcefully pull open the two doors that weigh 200 million catties in total, and invite Feng Wu back: "Then let's get ready to start, this is the inside of our forging room."

Feng Wu looked inside through the door, but he didn't see Yue Yang anywhere. He should have gone out to make preparations and search for some precious materials.

At this time, it was Dong Wu who was banging and hammering the forged iron inside.

Bare to the waist, with a sweat towel on his shoulders, when the door opened, there was a loud noise.

Take two more steps forward, and the heat is so hot that it hits your face.

"The positive yang energy is so strong, the core of the main channel of the yang meridian should be pulled into this room."

Feng Wu felt it and thought about it in his heart.

It's quite powerful, it took a lot of effort to extend the Yang Meridian to this lonely platform.

But it's really easy to use. Judging from the flame Dong Wu is using at this time, the temperature is stronger than his original one.

Dong Wen seemed to see Feng Wu's thoughts, and said from the side: "Zhengyang Earth can increase the power of flames.

This place is not only the place where my master chose to retreat and cultivate, but also an excellent treasure forged by the tripod caster. "

He said enviously to Feng Wu: "Here, using the yang energy of the earth veins to increase the flame temperature can greatly reduce the difficulty of forging with ordinary flames and increase the success rate.

It is a rare treasure.

However, it is better for you to have a different fire, and the different fire is the sun.

The upper limit of our flame temperature can be touched casually.

Unlike us, we usually have to find a day when the weather, location, and people are ready to start the furnace, and there are only two days in a year. "

Time, location, people and harmony.

Around noon on a sunny day in midsummer, here is the Zhengyang earth vein and the full state of the characters.

It is the time, location, and harmony of the caster.

A large part of the reason for Yueyang's refusal to seal Wu before was because of Yueyang's geographical advantage and people's harmony.

Been waiting for the best day to break through.

However, at this time, with Feng Wu's help from the otherworldly fire, although the three o'clock is still useful, it is not so important.

At this time, Dong Wu also finished forging the dagger in his hand.

Pick up the red-hot short knife with iron tongs, and press it fiercely into the quenching pool next to it.

With a snort, a large amount of white-blue gas rose up, and a few seconds later, a short blade with a blue lake-like luster on the surface of the blade was forged.

The liquid used for quenching is unusual.

It seems that what came out was a Tier [-] weapon.

"I'm fine." Dong Wu casually threw the dagger aside and said, "Our cauldron casting master is an advanced branch of the refining master.

We also know how to refine weapons, and we will teach you about ordinary weapons first.

There is no hurry to control the fire.If you want to control the flame well, you should start from the beginning, learn forging first, use a hammer to perceive and be familiar with various materials in your hand.

When it's time to control the fire, you will naturally know what temperature, heat and roasting time are needed. "

Dong Wu wiped his chest with a sweat towel, and spoke first.

And Dong Wen also responded: "Our forging is actually similar to your alchemy.

But it's slightly different.

Our forging materials are not as fragile as medicinal materials, but this does not mean that the requirements for fire control are not high.

Forging requires extremely fast changes in the fire.

Every time the hammer goes down, there is a slight change in temperature requirements. "

Dong Wen explained to Feng Wu: "Because every time the metal material is hammered, bumped and squeezed, and the internal structure of the metal material is compressed, the temperature of the beaten part will increase.

For example, when a piece of iron is forged, the more hammered the material, the brighter it is.

Even if the material is weaker, Dong Wu and I can hammer it to mature iron without using flames. "

With that said, the teaching has actually begun.

Dong Wu directly picked up a piece of ordinary pig iron with pliers and put it on the forging table for Feng Wu to demonstrate.

I saw that Dong Wu didn't use fire to cook the iron, just put it dry on the table in such a black and not slippery piece.

A hammer!
Dong Wu's arm swung into a full circle, drawing a perfect arc, with a feeling of fusion of strength and aesthetics.

Such power must be great!
"Bang-!"

In Feng Wu's sight, the pig iron didn't even have time to crack under the violent crushing, and was hammered into a discus.

To this extent, he can also do it.

But the most important thing is that now Dong Wu's hammer is a bright red, bright and hot cooked discus!

When the hammer went down, under Feng Wu's observation, the pig iron was directly twisted, and a large amount of black impurities were squeezed by the hammer and discharged from the inside of the pig iron, squeezed to the surface, and finally fell on the forging table, making a piece of black ash.

Inside the pig iron, under the force of extrusion friction, and the conversion of the kinetic energy and potential energy of the hammer, the energy is actually transferred to the pig iron, not the inside of the cooked discus.

Without using fire, the purpose of heating and roasting the pig iron was achieved.

The temperature is afraid that it will drop with a hammer, and it has risen to nearly [-] degrees.

At a higher level, now Dong Wen said that Dong Wu can beat this piece of iron into molten iron and seal Wudu's letter.

Although Feng Wu was a little puzzled before, after seeing it, he almost understood it.

As a good young man who has studied physics in the 21st century, he said that he can still read and understand.

The vision is different.

It’s true to say that Blue Star doesn’t have these mysterious powers, but I use science to understand some things within the scope of science.

Dong Wen, Dong Wu and the others are the top people in the industry, they may not be able to compare with some junior high school students of Bluestar 21st Century.

With Dong Wu's hammer, Feng Wu already roughly understood what they meant.

……

Popular science:

The melting point of iron: 1538 degrees.

The boiling point of iron: 2750 degrees.

In fact, what is forged and forged is carbon, and what is combined with oxygen to improve the purity is not completely considered as an impurity.

Even if forged too hard, the material will become brittle, which is not good.

As for the hotter the hammer, I pushed it down myself. I feel that if the heat dissipation is not calculated, there should be no logical problem.

(The popular science part is less than the charging threshold, and there is no charge.)
