Douba: I can upgrade everything infinitely

Chapter 192 Weapon Difference 【Subscription】

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

Because there is a variable that Dong Wu and the others increase the temperature by hammering the material, the temperature required for casting must not be constant.

When the hammer fell, the temperature of the material increased, and Feng Wu had to lower the temperature of the flame in that instant.

The temperature of the material will naturally drop during the hammering interval, and Feng Wu will naturally raise the temperature of the material again.

Moreover, because Dong Wen, Dong Wu and the others have different angles, directions, landing points, strengths, etc. of the hammer drop and the position of action, the results of the temperature rise in the material must also be different.

There must be slight differences in temperature at different positions of the hammered material.

The requirements are different, and when actually forging, the speed of the falling hammer is also very fast.

The control of Fengwu flame, the observation and prediction of material changes, and even the degree of precision, and the frequency of changes in fire temperature control are all very demanding.

Although in theory, the materials for these refining tools are much more tolerant than the plant materials that were mainly flowers, grass, wood, and leaves when Feng Wu was refining alchemy.

Within a certain temperature range, as long as it does not turn into water, it can continue to be built.

The temperature fluctuation range can even reach hundreds of degrees, thousands of degrees without waste.

Because metal is still metal when it is cooled, even if it melts into a liquid, it will still be the same when it is cooled and solidified.

Unlike refining medicine, if it is almost up and down, it will become ashes.

But Dong Wen said that a real craftsman would not forge in this way.

"If forged in that way, although the forged weapon can be used, it will definitely lose its 'soul'."

Dong Wen pointed to the weapons Dong Wugang forged and said: "Forging also has a 'soul'.

For us, the kind of randomly refined material is waste, which has been forged. "

As he said that, Dong Wen casually picked up a gray short blade from the side of the forging furnace. Feng Wu looked at such a weapon, and there was a pile on the side of the forging table, and there were plenty of them.

The appearance is not very good, but with a flick of Dong Wen's hand, it can be seen that it has been buried by other impurities and dust for a long time by the forging furnace.

It was actually a sharp blade with a cold light.

From the looks of it, it was also a Tier [-] sharp blade.

"Feng Wu, what do you think of this weapon?" Dong Wen raised the cold blade in his hand and asked Feng Wu.

"Fengrui, the third-level quality, the material is very good, and it should also be considered top-notch among the third-level gold and stone materials.

It should be made of pure gold, no worse than the iron mother of this casting house. "

Alchemists also have to know everything. Although these gold and stone materials are not the mainstream of alchemy, Feng Wu has dabbled a lot.

Feng Wu still has this insight.

"Well, it is indeed a third-tier dagger." Dong Wen nodded, confirming Feng Wu's answer.Then he raised the lake-blue dagger that Dong Wu had just created before and asked Feng Wu:
"Feng Wu, this dagger is also a third-tier weapon, so how do you compare these two weapons?"

Dong Wen is like a childhood teacher, guiding Feng Wu patiently.

Not to mention anything else, he and Dong Wu were indeed ahead of Feng Wu when it came to refining weapons and casting tripods.

And Feng Wubu was stupid, looking at the two weapons, he naturally understood that Dong Wen's question must have some deep meaning.

The third-tier dagger should be far inferior to Dong Wu's lake-blue dagger.

But Feng Wu still truthfully stated his thoughts: "I think the dagger should be slightly worse than the dagger.

But the same is the third level, the difference should not be much. "

"Crack-!"

As soon as Feng Wu's words fell, Dong Wen responded to Feng Wu with actions.

The lake-blue dagger fell sharply, and there was only an unpleasant rubbing sound, and the blade was embedded in the middle of the dagger about half deep.

If you push harder, it will definitely break!

In Feng Wuhe's eyes, he could tell at a glance that when the dagger was cut, when it was cut sharply, the material itself seemed to have a crack that was glued together.

After being cut, it is naturally damaged and untied.

Dong Wen took out the Hulan dagger, but the edge of the blade was slightly damaged.

However, compared with the dagger that was split in half, it was innocuous, and it was different from the crack of the dagger.

The lake blue short knife is more like a small piece of a whole that has been broken in a pure collision.

"Cracks! Cracks inside."

Feng Wu looked at the two weapons and replied, somewhat understanding what Dong Wen meant.

"Yes."

Dong Wen threw the two useless knives by the stove as if throwing garbage, and said:
"This is rubbish, the lowest level among Tier [-] weapons.

When I was young, I used it to play around, and it was a failure of forging.It's fine as a decoration, but if you use it to fight, you will die. "

Dong Wen patted Feng Wu on the shoulder and said:
"See? Temperature matters.

The reason why this Tier [-] dagger broke was because the material forging it had cracks.

The source of the crack is the uneven forging of the structure of the metal material.

Crunchy in places, heavy in others, soft in others...

There are only two situations that cause this material to be uneven.

The first is the technique, the technique we forge.

This happens when the level of the refiner is not enough.

Because he cannot handle this material perfectly and is not yet fully familiar with the properties of this metal.

Otherwise, not to say that the uniformity is perfect, but more than [-]% of the uniformity, and there is no problem with the unevenness in a small range.

Unfamiliar and incapable, this is the first situation. "

As he said that, Dong Wen suddenly raised his head to look at Feng Wu, and said, "Then there is a second situation, which is fire control!"

"Fire control?"

"Correct!"

Dong Wen kicked the broken knife on the ground and said, "Fire control is actually more important than forging under certain circumstances.

The fire control is good, and there are occasional mistakes. It is normal for the forged metal material to be heated unevenly.

However, if the fire control is not good, and the flame temperature fluctuates too much, there will definitely be uneven tissue density in various parts of the metal material. "

Dong Wen also casually summoned an orange beast fire, took out a piece of ordinary pig iron, let it toss up and down in the middle, and roasted.

"Metals even exhibit different properties at different temperatures.

Although it is still integrated in a large range, the difference can also be huge.

Forging the same material at [-] degrees and [-] degrees, the final result looks similar, but it is different in the eyes of us craftsmen.

differ greatly.

It can even be said to be a class I and class II material under a sequence.

And once the temperature of the flame fluctuates greatly, there will be a kind of metal that we forge and seven or eight different results that we think of as refiners.

Then knead together.

It's not like stack forging and alloy, which are all skillful blends.

Between each other, they are mixed together in a disorderly manner, with more distribution on one side and less on the other side, without any regularity.

There are too many types!

Naturally, there will be problems of unevenness of various materials.

There will be flaws. "

Dong Wen and Feng Wu said.

"So, the temperature of the metal must be kept within a certain range, the more stable the better?"

Feng Wu summed up what he said to Dong Wen, and thought for a while: "Then let me try first?"
