With each hammer stacked, the power possessed by Yin Mad gradually climbed, and reached its peak after a few breaths. Then came the rather boring monotonous output, Yin Mad maintained the strength of the hammer above a certain level, and constantly tempered the Xuantie.

His hammer is like a huge filter, constantly concentrating and squeezing the density of the dark iron, so that the impurities in its own structure are gradually highlighted, so as to achieve the effect of quenching.

Lu Xuan watched as the original skull-sized Xuantie shrank to the level of a fist under Yin Yan's continuous tempering, and he couldn't stop being terrified in his heart.

He knows a little about dark iron, which is a sharp weapon for forging blades, whether it is in terms of hardness or adaptation to the surrounding environment, it can be regarded as the most cost-effective material. And the most commendable thing is that the characteristics of the dark iron itself make it very easy to carry the magic circle, that is to say, painting the array on the dark iron is no longer so harsh on the array painter.

"Now that the density of this dark iron has reached almost its maximum, if it continues to be forged, I am afraid that it will hurt its own tolerance." Yin Mad didn't even have the slightest disorder of breath after a series of intense exercises, "Our forging process is a bit special, because it relies on our unique secret recipe. ”

With that, he placed the fist-sized piece of black iron on the forging table, and then his hand flashed, and a noble lotus flower appeared in his palm.

At this time, the lotus flower is waiting to be released, and the lotus exudes the breath of ice and snow, and the room that was originally full of heat waves opens up a cold area with the appearance of this ice and snow lotus.

Looking at such a magical thing, Lu Xuan's eyes also widened, but a question also jumped into his mind.

What is the purpose of Yin Mad sacrificing this ice and snow lotus at this time?

With such curiosity, he watched as Yin Mad's face was solemn and he placed the Xuantie, which was still in a red state, on top of the Ice and Snow Lotus.

For a while, it was like a boiling soup pouring snow, and the squeaking sound continued to spread around, and at the same time, the green smoke was rising, and the dark iron quickly cooled down, and soon returned to its original appearance.

Lu Xuan carefully looked at the Xuantie suspended above the Ice and Snow Lotus at this time, and found that it had undergone earth-shaking changes compared to before.

Although the previous Xuantie was cold and awe-inspiring, it was a little more shallow on the surface, but at this moment, the cold was deep and introverted, and if it weren't for the discerning people, they wouldn't be able to see its implied edge.

Is this tempering? A head-sized piece of black iron is only made into a fist-sized iron essence? That's an exaggeration, isn't it?

"This Ice and Snow Lotus is a treasure I obtained in a cave of heavenly blessed land in the early years, it has the effect of purifying the heart and nourishing the spirit, at the beginning, I used the cold qi released by it to repair it, and the cultivation speed was several times that of before! But in recent years, I've found that it works well for quenching, so its main role now is to follow me in forging weapons. ”

Lu Xuan was not at all interested in what Yin Yan said, his eyes looked at the small ball suspended above the ice and snow lotus in a daze, this dark iron essence is commonly known as iron essence, it is showing its unique charm, hazy and subtle, it is obviously a blazing and fierce power but it is covered by a layer of thin veil, this contrast is jaw-dropping.

"What are you staring at here? What can you see when you look at it this way? Yin Yan looked at Lu Xuan like a fool, and then took off the iron essence and gently wiped it with his hand.

It's okay if you don't wipe it, but when you wipe it, a dazzling light is straight to the human eye, which makes Lu Xuan can't help but squint his eyes.

As Yin Mad wiped it vigorously, the dust covering the iron ball naturally faded. As the so-called Longyou Shoal will eventually have the day of thunder, the treasure bead will be covered with dust and will shine with incense, and at this moment, under Lu Xuan's nose, is a white and flawless and sharp cold light.

Seeing Lu Xuan's shocked expression, Yin Yan immediately showed a disdainful smile and said, "Do you think this is the end of the matter?" ”

"Isn't it over yet? Is it so difficult to quench a piece of iron essence? ”

"If you have a mindset of indifference, then there is no real problem in this world, but you can keep improving and go far from it, and what can really make you feel tricky is always yourself." Yin Yan smiled slightly, and then he picked up the iron ball, threw it casually, and threw it into the huge stove in the center of the room.

The roar of the flames instantly drowned everything around them, and even the tinkling sound of the dozen or so strong men was almost imperceptible.

After a long time, Yin Mad took out something similar to straw out of nowhere, put it in his mouth and chewed it.

"Do you eat? It is used to clear away heat and detoxify. ”

Lu Xuan looked at the thing that Yin Mad handed over, hesitated slightly, took it, and put it in his mouth.

At first he refused, because he didn't believe it could taste good. However, when he began to chew, a sweet fragrance like a mountain spring permeated his mouth, and this smell went down his nose and throat to the five senses, giving him a sense of sudden sunshine after the rain.

This feeling is a good medicine in such a stuffy atmosphere.

And this kind of thing is very chewy, even if you chew it in a big bite, you can't chew it all in an instant, so Lu Xuan is relieved to eat it boldly.

Time passed bit by bit, and when he felt a little tired, Yin Mad, who was waiting beside him, suddenly moved.

I saw it stand up, wave its hand forward, and the iron ball leaped out of the iron furnace and suspended in midair.

At this time, the iron ball carries an endless amount of heat, and it seems to be between the melted and the unmelted, with a slimy feeling.

"Quenching a piece of iron essence is far from over." Yin Yan smiled faintly, threw the crimson iron essence on the forging table, and then swung the hammer again, as if it were tempered as before.

Because in the iron furnace, the iron essence has been softened by the scorching, so every time Yin Mad hammers down, he will shape it.

Over time, most of the heat on the iron essence has been dissipated, and the iron essence has also transformed into a solid state, regaining its indestructible hardness.

Feeling the changes that had taken place on this, Yin Crazy Ming obviously began to get anxious, and his hammer drop speed was also faster than a moment, and more than ten hammers fell in an instant!

Under the stormy bombardment, the Iron Spirit finally regained its solid state, and although it was still red, the passing temperature did not allow it to continue to soften.

At a certain moment, Yin Yan's eyes crossed a trace of fierceness, and then the hammer slashed a beautiful arc in mid-air, and finally bombarded it like the top of Mount Tai.

This time, Yin Madness did not accept the move, nor did he use the power of his human body to export the diffused airflow, but let the airflow rampage through the air around him.

Lu Xuan was shocked by the momentum, and his steps retreated again and again, forcibly stabilizing his body.

"Is this the end of it?" Lu Xuan looked at Yin Mad, who maintained his last move, and couldn't help asking.

However, when he heard Yin Yan's answer, he realized how naïve he was.

"You're going to be done with this? Quenching is the process of continuously removing impurities from the metal, if the purity of a piece of metal is higher, its use value will inevitably rise. Nine is the extreme, and only by constant repetition can it be possible to achieve success. ”

After Yin Yan finished speaking, he put the piece of iron essence on the Ice and Snow Lotus again to cool it down, and then threw it into the furnace again!

In the following time, he kept repeating this process, and the iron essence, which had already had the signs of a peerless orb, changed its appearance again, showing a diametrically opposite appearance.

When the last time, Yin Mad put the red-hot iron essence on the ice and snow lotus to cool it, erasing the impurities that appeared on it, and the final product was also displayed under Lu Xuan's nose.

"This ...... That's it? Lu Xuan hesitated.

"Of course, the impurities of the last time are much less than before, and the presence of impurities is almost not felt on its surface after cooling, so this piece of iron essence is also a qualified product."

Lu Xuan stepped forward and stared at this iron essence for a long time, the current iron essence was less than the weight of a fist, and it was only about the volume of half a fist.

That is to say, in the repeated quenching, the lost part is removed, and what remains is impurities.

"How is this iron spirit not gray?" Lu Xuan asked incomprehensibly.

Yin Yan smiled slightly: "This is also a natural phenomenon, just like a monk who became famous at a young age, if he wants him to learn to restrain his edge, he will only follow the cat and the tiger, because he feels that he should be arrogant from the bottom of his heart, and he can't wait for the whole world to know his ability." But have you seen how many old monks have this kind of fierce and fierce mood? After seeing through the essence of the world, then the entanglements in the world have become insignificant barnyard grass. What's the point? ”

When Lu Xuan heard this, he once again concentrated his realization on this iron ball, and he suddenly realized.

The first time, he thought that the iron essence was introverted and profound, but it was just deceived by impurities, and now without impurities, it can already show a feeling of ancient wells without waves, which is the highest state of life.

"So what should I do next?" Lu Xuan asked.

Yin Yan smiled mysteriously and said, "The dark iron is too hard to be tempered by a rookie like you, so I'll give you ordinary metal for you to forge." According to the process I just made, you will give me the metal to be checked after quenching, and you will also feel the changes that have occurred on the metal in the process. As the so-called unity of man and hammer, as your object, every aspect of metal is an attribute that you should estimate. ”

With that, he took out a large piece of metal from his bosom, which revealed a red glow and a faint ruby feeling.

Under the reflection of this transparent and luster, Yin Mad said: "This metal is rhoite, as long as you reduce its impurities within half a multiplication, you will complete the task." ”
