Lu Xuan scoffed at this request, because in his impression, if there was a purity requirement, it would naturally be associated with the immortal spirit grass liquid that also required purity.

After all, extracting the Immortal Spirit Grass Liquid was a relatively easy task, and he was now able to control the proportion of its impurities within five percent.

What is the essential difference between purification and purification?

When Lu Xuan had such thoughts, Yin looked at his emotions and knew that he was destined to suffer for his assumptions.

"You don't need to use too good utensils or anything, after all, this rhedrite is not a high-quality mineral, and an ordinary iron hammer can temper it. As long as you can successfully temper this red crystal, I will promote you to an intermediate blacksmith. ”

"Intermediate blacksmith? What's the benefit of that? Lu Xuan asked.

"The good thing is that you're worth more when you work. In other words, it will take 10,000 years to pay off your debts at your current level, so when you are promoted to an intermediate blacksmith, it will only take 5,000 years. ”

"So long?" Lu Xuan's mouth opened wide, as if he had heard some unbelievable news, "Then wouldn't I have to spend all my time here in my life?" ”

Yin Mad pretended to be mysterious and said: "You can't say that, if you want to end the work of ironwork as soon as possible, then you need to constantly improve your strength." As long as you can move up to the higher levels, your time will be worth a lot of money. ”

Lu Xuan suddenly heard this, and in the end, he fell into another system, and only by climbing to the top could he continue to cultivate.

Thinking of this, Lu Xuan didn't know what his heart was like, if it was melancholy, then he still faintly had surging blood, after all, being able to witness his progress with his own eyes was far better than aimless depravity, and delayed gratification was always the first source of sublime happiness.

However, if you want to say that he is happy, the worry in his heart suppresses his heart all the time. After all, the distant goal always exudes mystery and nothingness compared to the present, and will pose a serious threat to his self-confidence.

"In that case, I have nothing more to ask for than to quench the red-hot minerals in the water over there. However, it is important to note that you can only use a container to get water from it, and you can't put the metal directly in the pool to cool down. ”

Following the direction of Yin Yan's finger, he saw that there was a pool at the foot of this room, and the pool contained clear spring water. At this time, a large man took a metal basin and took water out of the pool, and then placed the red-hot metal in it.

A wisp of smoke rose as she heard Zra, and then the temperature of the metal quickly dropped.

Lu Xuan nodded lightly, and then Yin Mad patted him on the shoulder as if comforting, and said in a low voice: "Ask for more blessings." ”

After saying this, he swaggered away with a wicked smile on the corner of his mouth.

Asking for more blessings? Lu Xuan snorted disdainfully, just such a metal mineral, can it stump me?

Lu Xuan picked up the small hammer as if he didn't believe it.

However, the weight of this hammer far exceeded his expectations, and in his imagination, this hammer must be very different from the half-human giant hammer of Yin Mad, so it could not be so heavy that it was difficult for him to control.

But his idea turned out to be extremely naïve, and although the hammer seemed relatively small and light on the forging table, it fell into his hand and pulled his body down as if it were a thousand pounds.

His face turned red, and his forearm instantly felt sore, and he finally lifted the hammer in the air.

But it trembles, and it is impossible to control it from falling and forming an effective smashing force. Because if it can't be effectively controlled during the fall, the hammer will bounce off the target as soon as it hits it, with terrible consequences like derailment.

He turned his head to look at Yin Mad's back gradually moving away, and then looked at the other strong men who were busy in full swing, and couldn't help but smile bitterly, holding the hammer in both hands and carefully placing it on the forging table.

It seems that things are a little unusual, can we only rely on true qi? You must know that it is not impossible to use true qi, but these strong men do not have the slightest intervention of true qi in their sweaty labor, they completely rely on their own physical strength, like arms and fingers to control the hammer to rise and fall, so mechanical repeatedly.

Since you have entered this environment, you should be strict with yourself with its rules. Lu Xuan's eyes showed a determined look, he looked at his hands, and in a trance, the body armor covered the surface of his body.

The power of the body armor lies not only in the dragon on its body, but also in the infinite power generated by the change of the physical pattern.

This power is truly derived from the limbs and bones, and has a diametrically opposed way of operating from the true qi.

After releasing the body armor, he grabbed the handle of the hammer tightly, gritted his teeth, held it in the air with one hand, and then fell hard!

"Dangchang!" Although the sound was huge, it was not worth mentioning in such a noisy environment, and Lu Xuan couldn't help but be surprised when he saw that the red crystal stone did not move at all, and not even a crack appeared.

How hard does this red crystal have to be? Even if it's not heated, it's not so bad that you can't knock it at all!

With this in mind, he had to put the red crystal in the furnace and roast it.

Rhocite is an ore abundant in the north, and the essence of the sun and moon contained in it should not be underestimated. The most common use of this mineral is to make coins, from which monks can draw true qi, so the purity of the red crystal used to construct the coins can determine the degree of essence of the true qi that the monk draws.

In many parts of the Chiyang Dynasty, this kind of coinage made of red quartz was quite popular among monks, and even special places were opened to provide red quartz for customers to absorb, so as to charge venue fees and service fees.

Lu Xuan really didn't expect that the things he was accustomed to would be so difficult to make. Maybe it's because you're too vegetable?

While he was thinking about it, he saw that the red crystal had taken on a translucent state, and knew that the time was up, so he immediately took it to the forging table, and then picked up the hammer and smashed it fiercely.

The powerful reaction force made his tiger's mouth feel a violent shock! The pain was overwhelming, causing his eyes to shrink into pinholes in an instant.

Now he realizes that he faces a more realistic problem.

That is, the ribbing of the hammer handle is used to increase friction, but it is precisely because of this ribbing that the skin of his palm is seriously rubbed!

He gritted his teeth and swung his hammer again.

It would be impossible to say that such a hammer blow had no effect at all, but it would be pure nonsense to say that it was quite effective. I saw that the surface of the red crystal was slightly concave, and if I didn't look closely, I couldn't even see the existence of the depression, and this was the result of Lu Xuan's two hammers.

In this way, he endured the pain in his palm, and kept swinging the hammer.

According to other people's standards, ruitol can be easily done with a few hammers, after all, this kind of thing is still a low-end commodity among blacksmiths. But for Lu Xuan, a beginner who has just stepped into the threshold on his front foot and has not yet kept up with his back foot, it is difficult to temper this kind of thing.

The severe pain and strong sense of exhaustion made Lu Xuan feel like he was in purgatory all the time, but even under such circumstances, he was still immersed in monotonous tempering.

I don't know how many hammers have gone down, and finally the red crystal has shrunk a circle, his eyes are dizzy, he gasps and puts the hammer down, and then releases the hammer handle, and the handle spreads his palm.

I saw that his palm at this time was pink and bright red, which was the flesh exposed after the skin was worn out, although this pain was not to the extent of dying or living, it was enough to make people drink a pot.

In fact, the most test for Lu Xuan was how to continue to hold the iron hammer handle with such a palm, and let it destroy the palm without the slightest protective measures.

He carefully took out a basin of water from the container and placed the rhedrite in it, and then the rhothite made a slight zila sound.

Lu Xuan frowned and looked at this scene, knowing that he had been hammering for too long, causing most of the temperature on the red quartz to dissipate.

However, if it is not fully hammered, it is impossible to have the effect of tempering, that is, tempering and cooling, these two steps determine the speed of removing impurities, and if you continue to explore, this process can even determine the final color of the red quart.

Knowing this, he had to keep the metal in the furnace and continue to heat it.

Somewhere in the room, Yin Madness and Yin Lie quietly watched the busy figure of the young man.

"What do you think of Lu Xuan's child?" Yin Lie asked.

A meaningful smile appeared on Yin Maan's face and said, "It's too early to make a conclusion, after all, the difficulties he encountered are only the most basic, if he can't even overcome this, then don't expect him to be able to achieve the above results on the path of cultivation." ”

"Well, but he's a lot stronger than I was." Yin Lie also smiled, "At the beginning, the blood from the grinding of my palms flowed, and my grandfather chased me for eighteen streets before he grabbed me and continued to press in front of the forging table. ”

"This is the starting point that every blacksmith has." Yin Madness looked at Lu Xuan's figure with interest, and a complicated expression appeared in his eyes, "You said that what he performed was really the Dragon Roar Returning Yuan Body?" ”

When Yin Lie heard this, his face also became solemn, and he and Yin Crazy glanced at each other, both of them confirming something from each other's eyes.

"Although it is similar to the Dragon Roar Returning Body in some characteristics, it remains to be seen whether it is really this divine skill. But now what is certain is that even if this kid is not using the Dragon Roar Returning Body, this martial art can already be called a divine skill in physical cultivation! ”
