Sacred Dragon Douluo of Douluo Continent

Chapter 100 Learning...
As a result, Tian Peng threw the ore handed over by Wu Sansi into the furnace without looking at it, and the whole piece of ore hit the tray in the furnace, causing sparks.

Fuck, this is too rough, is this how metals are refined, directly calcining a whole piece of ore?I don't read much, don't lie to me!

"Extract the hematite from this hematite ore, and then forge it into an iron ingot. This is your next task. I will teach you what to do next when it is completed."

After finishing speaking, without waiting for Wu Sansi to react, he walked to an operating table and continued his work. The figure carrying the back clearly didn't care what Wu Sansi did.

Picking up two black hammers with both hands, and looking at the crackling ore being calcined in the furnace, Wu Sansi was in a mess.

Recalling how Tian Peng extracted the metal from a piece of ore yesterday, um, I can’t remember it at all. It seems that there was such a hammer. The whole piece of red iron stone has also shrunk a lot.

But knowing that it was the seemingly ordinary hammer that removed the impurities in the red iron stone, but Wu Sansi didn't know how to do it!

Putting these aside first, Wu Sansi used the tongs on the side to dump the burnt red iron in the furnace into another stone tray.

Taking out this tray that looked like magma from hell, looking at the scattered gravel inside, Wu Sansi was about to cry. He didn't expect that it would be so difficult to extract metal from the ore. Then we will purify the metal later!
Pour out the slag and a small amount of residual metal liquid in the original tray, scrape off the small stones in the melted hematite solution, and then pour them back into the original tray. After repeated several times, Wu Sansi finally extracted a metal that is almost naked-eye. The hematite solution with no other impurities could be seen.

While waiting for the red iron solution to cool down, Wu Sansi secretly glanced at Tian Peng who was turning his back, and found that he had no tendency to turn around, so he continued to forge his exclusive 'skills' with confidence.

The hematite solution cooled very quickly, Wu Sansi took out the semi-condensed hematite stone from the tray and put it on the anvil, and dragged a small stool from the side to support it, ready to forge the metal.

"Bump~ bump~ bump..."

Wu Sansi opened his bow left and right, and hit the hematite stone with a black iron hammer on both sides at the same time. It didn't have the impact of metal collision as he imagined, but it felt like knocking down the sandbag. Maybe it wasn't cooled enough.

Continue to beat, the temperature of the red iron stone is getting lower and lower, and it is getting harder and harder. Fortunately, his physical fitness is really good, and Wu Sansi didn't even break a drop of sweat after beating this time.

After the red iron stone was almost completely hardened, Wu Sansi knocked it into a nearly square metal ingot, at least Wu Sansi thought it was a cuboid.

"Teacher, it's all right." After hesitating for a long time, Wu Sansi decided to tell Teacher Tian, ​​after all, he didn't know what to do next.

"It's still early! This is for you. When it reaches 90.00% or more, it's barely finished." Tian Peng threw a metal detector to Wu Sansi.

Metal detector, Wu Sansi knows that this is used to detect the purity of metals, it contains the inspection records of most metals, can quickly distinguish the purity of this piece of metal, it is a soul guide that is often used device.

After receiving the metal detector, Wu Sansi swipe across the hematite without any hesitation, thinking that the purity of his hematite should be more than [-], it looks so pure!

drop!
The metal detector beeped, and 70.00% two appeared, a number that Wu Sansi couldn't imagine.

Why?Obviously it looks quite pure, there are no other colors on the surface?
Wu Sansi couldn't figure it out, but he knew that the metal detector Tian Peng gave him would be fine. Could it be that there are so many other impurities in this hematite stone?

I can't figure it out, but it doesn't stop him from throwing the hematite back into the furnace, at least he understands the reason why repeated forging can purify it.

After another beating, Wu Sansi took the metal detector to test again, 70.00% four, what the hell?The purity has only increased by two percent?
Wu Sansi, who does not believe in evil, returned this piece of red iron stone to the furnace to reforge. When forging, not only increased the strength but also extended the time, but the final display was indeed 70.00%. Quite few.

Then return to the furnace, 80.00% six.

Then return to the furnace, 80.00% nine.

Then return to the furnace, 90.00%.

ninety one,

ninety two,

ninety twenty five,
ninety twenty seven

Ninety twenty-eight.

It was repeated forging more than ten times, and finally reached the purity of 95. In the last few times, it was almost improved by [-]% each time, but this time it was forged just now, it did not improve at all.

What went wrong?My proficiency in each forging is improving. A total of twenty or thirty beatings have trained Wu Sansi in a decent way. At least the strength and speed of each sagging are well mastered, but this purity is not there. The slightest improvement, I can't figure it out.

After several attempts, Wu Sansi found that no matter how he changed the way of beating, the purity of hematite could not be improved.

In the end, he simply dropped the hammer and sat cross-legged on the ground to run his soul power to restore his physical strength. After all, he was still a seven-year-old body. Even if his physical fitness was good, he couldn't help but feel a little tired after so many exercises.

How can we continue to improve the purity?Did I miss any process or add some auxiliary materials?Obviously, Mr. Tian’s tempering did not add any help yesterday. He can forge such a beautiful iron ingot just by simply beating it. There is no reason why he can’t forge it!
The high temperature brought by the continuous burning of the stove made Wu Sansi, who was already a little tired, couldn't help sweating profusely. Beads of sweat kept dripping from Wu Sansi's forehead, and gradually left a water stain under his body.

Sweat soaked the clothes all over his body, and the feeling of being wet was very uncomfortable. Wu Sansi used his soul power to evaporate all the sweat all over his body in an instant.

The soul power is really easy to use. It seems that yesterday when Mr. Tian was forging, there were fluctuations in the soul power. Is there any connection between this?
As soon as he thought about it, he did it, Wu Sansi got up quickly, threw the hematite that had been forged into brown into the stove, and took it out after burning until it was red.

Grabbing the double hammers and slowly lifting them up, slowly wrapping his soul power around the two black iron hammers, Wu Sansi seemed to feel that the two hammers were like an extension of his body, without the stagnant feeling of using tools at all.

At the same time, the moment Wu Sansi's soul power came out from his body, Tian Peng also stopped what he was doing, and he froze in a daze, as if a statue stood there motionless...
