The second day is noon.

Lie said in the air!

Lu Shaoyu carried a tattered machete on his back and came to the mountain ridge where he practiced secretly.

After more than a month, some low weeds have grown on the flat ground here. Lu Shaoyu looked around, carefully paying attention to whether there were any suspicious marks on the boulders around here. After turning around, I didn't find anything suspicious, and it is estimated that no one has been here for more than a month.

With a slight smile on the corner of his mouth, Lu Shaoyu quickly moved a few boulders around him and arranged a simple defensive magic circle to block the vision in the distance. Then, he began to take out the alchemy stones, jade slips, rune paper and other items, and arranged the magic circle in the open space.

This magic circle is relatively complicated, and there are a lot of array materials used, Lu Shaoyu is extremely cautious, meticulous, and very carefully arranged.

This magic circle has been arranged for more than two hours. There are hundreds of giant jade runes used, and the most eye-catching is the jade mirror the size of a palm, which is full of thirty-six palm-sized jade mirrors, and many mysterious runes are carved on the mirror.

After the formation was completed, Lu Shaoyu looked up at the fierce fire in the sky, and muttered to himself: "The sun is fierce today, which is just right for making fire." ”

As he spoke, his hands quickly changed the magic seals, and one by one the mystical power runes burst out from his fingers and fell into the surrounding arrays.

Lu Shaoyu walked around while pinching the trick, his body turned more and more, and the Xuanli runes turned out between his fingers and blended into the surrounding stone platform.

These stone platforms absorbed Lu Shaoyu's Xuanli runes, exuding a faint white glow, as if they had been activated.

A few quarters of an hour later, Lu Shaoyu played the last rune, closed his palms, and drank softly in his mouth: "Nine Heavens Yang Huo, gather for me!"

"Hum. ”

The large array whispered softly, and countless white rays of light rose from the array, intertwining with each other, forming a huge funnel-shaped pillar of light, radiating towards the sky, instantly enveloping the surrounding places.

This huge funnel of white light flickered and disappeared, and then disappeared in the blink of an eye, as if it had merged into the sky, and disappeared from its form.

As the white light funnel disappeared, the blazing sensation that had been under the scorching light disappeared at this time, as if the sun was blocked by a black cloud.

All of a sudden, it became much cooler, as if the sunlight had been absorbed!

Within the large array, the runes on the thirty-six white jade mirrors flashed with strong light, and they absorbed the sun's rays within a mile of the surrounding area, reflected through the mirrors, and gathered in the center of the circle.

Thirty-six dazzling pillars of light converge into one point!

At this point, the temperature soared instantly. In an instant, with the point of light as the center, a blazing pale white flame like a transparent flame slowly rose above the mid-air in the center of the circle.

The flame, which was only the size of a fist, floated in the middle of the circle, and thirty-six pillars of light continued to gather sunlight to keep the flame burning. A fierce and blazing temperature spread from this white transparent flame.

This flame was the yang fire formed by Lu Shaoyu using the magic circle to gather sunlight within a mile around the mountain, and its temperature was dozens of times higher than that of ordinary flames.

Looking at this slowly burning sunlight, Lu Shaoyu stretched out his hand, and the mysterious force gushed out, and a gravitational force attracted the broken knife not far away. Then, he wrapped his hands around him, and both palms simultaneously cast a gravitational spell, controlling the broken knife to slowly approach the flames.

The temperature of the yang fire was extremely high, and when this broken knife came into contact with the flames, it was burned red in the blink of an eye. Lu Shaoyu controlled the mysterious power of the machete, which was also quickly consumed due to the high temperature.

Lu Shaoyu had already expected that, while controlling the gravitational technique, he was running the exercises of "Taiyi Daozang", absorbing and transforming the Xuan Qi between heaven and earth into his body to replenish the consumption of Xuan power.

The yang fire burned slowly, and the broken knife became more and more red, and there was a faint feeling of being burned.

Taking advantage of the fact that the broken knife was calcined by the flames, Lu Shaoyu opened his mouth and sprayed, and a mysterious force mixed with sharp gold qi erupted from his mouth, quickly pouring into the red-hot blade, helping the broken knife melt.

Time passed slowly, and the sunlight in the sky was gathered and turned into a slowly burning yang fire, constantly calcining the broken knife. And Lu Shaoyu would also spray a mouthful of the mysterious power of the sharp gold qi on the knife body every once in a while to help the knife body melt.

After a meal, the knife finally began to melt slowly, and it began to turn into a ball of red molten iron, which grew larger and larger, and with the support of Lu Shaoyu's cause technique, it was suspended above the flames, constantly changing shapes.

The big knife melted more and more, and the red bead of molten iron gathered from the size of a finger to the size of a fist. Some of these impurities also dissipate quickly under the calcination of the flame.

This knife was originally made of 100 refined steel, there are not many impurities, after melting into molten iron, the impurities basically dissipate more than half, as long as a little calcining and separation, you can extract the iron essence from it.

"Oh, that's not right!"

When an arm-long broken knife melted to the length of a palm, Lu Shaoyu's eyes froze and he found that something was wrong.

The broken knife that burned in the flames didn't seem to melt anymore, leaving only a palm-long black iron bar, no matter how it was calcined, it didn't dissolve, and even the color didn't change!

It's still pitch black, not red!

"It's ......"

Lu Shaoyu controlled the molten iron ball with one hand, but with the other hand, he made a move at the palm-sized iron bar, and a gravitational force attracted the iron bar on the flame.

Lu Shaoyu asked it to stop half a foot in front of him and looked at it carefully.

This iron bar is black and inconspicuous, but Lu Shaoyu felt that the temperature on the iron bar was actually cold and cold, as if it had been calcined by the yang fire for so long just now, but it did not get hot at all.

Feeling that the temperature on the iron bar was not high, Lu Shaoyu beckoned, and the iron bar fell into his hand.

This iron bar is extremely heavy, and Lu Shaoyu estimated in his heart that half of the weight of this broken knife is probably the weight of this iron bar.

"What is this?" Lu Shaoyu put it in front of his eyes and looked at it carefully.

Because it had been burned by fire, the surface of the iron bar had a faint layer of black iron scale.

Lu Shaoyu scraped the iron scale with his fingernails, and when he opened his eyes, he saw that on this iron bar, there were some dense white spots in the black.

These white spots are very thin, but they can be seen clearly!

"Xingchen Essence Iron ?!!," Lu Shaoyu shouted in a lost voice.

Star Iron, an essence left over from the burning of meteorites from space, is an extremely precious refining material. The flying sword in Lu Shaoyu's previous life was made by fusing Xingchen refined iron and other precious metals.

Xingchen Essence Iron is extremely difficult to melt, and although the temperature of this Yang Fire is high, it is far from reaching the level where it can be refined.

"No wonder!" Lu Shaoyu thought to himself.

Looking at this palm-sized flat star iron, he smiled slightly, he noticed that there seemed to be something in this broken knife, but he didn't expect it to be such a treasure, dare to love the guy who cast the knife at the beginning After getting this piece of star iron, he couldn't melt it, so he threw it directly into the iron billet and cast the knife together.

Fifty taels of silver for a piece of star iron, it's worth it......
