After saying goodbye to Mu Ya, Han Chen went straight to the Will Auction House, entered the hall, squeezed through the crowd, and came to those crystal cabinets. Directly purchased enough herbs to refine ten copies of the 'Yuan Spirit Liquid'.

Although these herbs are not rare, they are not expensive. But it also cost Han Bing more than 15,000 gold coins.

However, Han Chen couldn't care about being distressed at this time. Putting the herbs into the empty ring, Han Chen wasn't even interested in going in the inner hall to take a look, so he hurriedly left the auction house and walked out of Black Rock Town towards the woods.

After a while, Han Chen came to that clearing.

Turned over and jumped on the boulder, stroked the empty ring with his right hand, and then saw a few dried herbs, some broken weapons, a few messy materials and a black stone flying out of the empty ring one by one, and landed on the boulder, all of which were purchased from Mu Ya before.

Although there weren't many things, there were also a small pile, and Han Chen's eyes were staring directly at the black stone in it, and he wasn't even interested in taking a look at other things.

After a long time, Han Chen reached over and picked it up.

Slightly heavy, Han Chen's eyes carefully looked at the black stone in his hand.

The stone is not big, only the size of a palm, but the weight is not light, according to Han Chen's estimate, such a small stone is estimated to weigh nearly a hundred catties.

However, no matter how Han Chen observed, he didn't find anything special, except that it was heavier, it was completely no different from ordinary stones.

"Teacher, is this what you're talking about?" Han Chen, who had been looking at it for a long time and still found nothing, couldn't help but be a little discouraged, and asked suspiciously at Guiguzi, who appeared in front of him at some point. It was Guiguzi who ordered it before, and Han Chen would buy it.

"Well, this piece is 'Meteorite Adamantite'. Looking at the black stone in Han Chen's hand, Guiguzi said slowly.

"Meteorite Essence Gold?" Hearing this, Han Chen was stunned.

Looking at Han Chen, who looked confused, Guiguzi slowly explained: "Meteorite Essence Gold is an excellent refining material, which can only be formed by the high-temperature smelting of meteorites outside the sky. However, it is good that ordinary extraterrestrial meteorites can form a thumb-sized piece. Such a large piece of meteorite pure gold is rare. ”

"The formation conditions are so harsh?" Hearing Guiguzi say this, Han Chen couldn't help but be stunned.

It's no wonder that Han Chen was surprised, knowing that the meteorites outside the sky are not like rain, they can be seen often.

Sometimes it doesn't happen once in years, even decades. And not every time an extraterrestrial meteorite appears, meteorite will be formed. It is not easy to form a thumb-sized amount of meteorite gold. Not to mention that it is so big.

"Well, it's hard to form bars, but that's what makes every piece of meteorite gold extremely pure and hard. As long as you are refining the weapon, add a piece of meteorite iron pure gold the size of a fingernail. It can increase the hardness of the refined weapon by several levels. It can be described as an excellent refining material!" Guiguzi nodded and said with a sigh.

"Hehe, you're lucky to be able to find such a large piece of meteorite gold. As long as you collect some other materials, you can refine a weapon for you!" After a pause, Guiguzi looked at Han Chen and smiled lightly.

"But I see that Mu Ya has an extraordinary conversation and a good temperament, it shouldn't be as simple as an ordinary mercenary, and I see that his face is pale, his breathing is uneven, and he is obviously injured. All of this shows that this Mu Ya is not an ordinary person, and besides, the reputation of the forging master on the Purple Gold Continent is no lower than that of the alchemist. Even an ordinary person would know a few pieces of refining materials that could be forged, how could he not know this piece of meteorite pure gold!" Han Chen said with a slight frown.

"Hehe, meteorite iron pure gold is extremely rare, even if you have lived for thousands of years as a teacher, you have only seen it twice, and among those forging masters, it is estimated that only forgers with more than five grades can know the existence of meteorite iron pure gold in the Dao, but it is not necessary to see it or not, and some of those who are unlucky may not have seen it once in their lives. As for those of lower grades, you may not have even heard of them. Besides, do you think that the black stone in your hand is the true appearance of meteorite pure gold?" Guiguzi shook his head and laughed.

Hearing this, Han Chen was stunned.

Guiguzi didn't say much, his right hand raised two fingers, tapped the center of his eyebrows, and suddenly a little red light appeared from the center of his eyebrows and fell on Guiguzi's left hand.

"Peng!"

The red mangs turned into a bright red flame like blood, jumping and rising in Guiguzi's left hand. It is the true fire of samadhi.

Guiguzi's fingers moved slightly, and then he saw the rising bright red flame slowly shrinking, but in a moment, it shrank to a foot above Guiguzi's palm.

Looking at Guiguzi's exquisite fire control technique, Han Chen's eyes were full of envy.

Guiguzi smiled slightly, after these months of meditation, the soul power consumed by arranging the giant Bagua Array in Han Chen's sea of knowledge had already recovered, and it had even improved slightly.

He waved slightly, and then saw that the palm-sized piece of meteorite iron essence gold in Han Chen's hand was wrapped in soul power and thrown into the samadhi true fire.

As soon as the meteorite pure gold was thrown in, the bright red flames of blood surged up, enveloping it, and began a violent calcination.

Guiguzi's five fingers moved slightly, mobilizing the temperature of the flames in it.

A moment later, Guiguzi Guiguzi closed his eyes and controlled the calcination of the flames only by relying on his soul perception.

For a moment, the forest fell silent again, and Han Chen just sat next to him, his eyes staring at the bright red flame, and time passed slowly

In the glade, a naked teenager was moving and jumping rapidly.

"Splitting the Mountain!"

Looking at the palm print pit on the trunk that was only seven or eight centimeters deep, Han Chen shook his hand and shook his head slightly.

Tilting his head, looking at Guiguzi, who was still sitting cross-legged on the boulder, calcining the meteorite essence for more than an hour, but still showing no signs of ending, Han Chen shook his head helplessly.

Although Han Chen was very curious about the refining weapon, looking at the almost black meteorite essence gold wrapped in the bright red and blood-red Samadhi True Fire around it, calcining it without moving, Han Chen deeply sighed that this meteorite iron essence gold was hard, but also felt a little bored.

He jumped off the boulder and went to the clearing to begin practicing the few volumes of Yellow Rank Combat Techniques that he had read in the Sword Pavilion last time.

However, the Yellow Rank Combat Technique was the Yellow Rank Combat Technique, and it could not be compared to the two Xuan Rank Combat Techniques in Han Chen's hand at all.

Just as Han Chen was about to continue his cultivation, he suddenly noticed that there was a change on Guiguzi's side, Han Chen was stunned for a moment, immediately stopped his cultivation, walked quickly to the side of the big stone, and turned over and jumped onto the big stone.

His eyes stared straight at the meteorite gold wrapped in bright red flames.

After the terrifying high temperature of the Samadhi True Fire, more than an hour of calcination, at this time, the surface of the meteorite iron and pure gold had already appeared a slight crack, like a cracked crack in the ground, densely covering it.

Only after the time of tea, the cracks on the meteorite fine gold expanded again, and finally fell off.

As soon as the fragments that had fallen off left the meteorite pure gold were calcined into nothingness by the Samadhi True Fire.

Gradually, the fragments fell off, and then they were calcined to nothingness by the terrifying heat.

Eventually, all the fragments of the Meteorite Adamantite were calcined off and burned to nothingness. At this time, the meteorite adamantite had shrunk from the size of a palm to the size of a fist.

At this time, Guiguzi also slowly opened his eyes, looked at the fist-sized piece of meteorite iron essence gold in his palm and smiled slightly.

As soon as his mind moved, the bright red flame was extinguished, turning into a little red light and re-burrowing into the center of Guiguzi's eyebrows.

The fist-sized piece of meteorite iron and pure gold also landed on the boulder.

"Meteorite fine gold is smelted by meteorites outside the sky at high temperatures, and the temperature on it is also extremely terrifying, after falling to the ground, the terrifying high temperature will immediately incinerate everything around it, and after the temperature is cooled, there will be some impurities attached to it, and the fragments that have just fallen off are those impurities. Guiguzi smiled slightly.

Hearing this, Han Chen carefully looked at the meteorite essence gold that had been refined by the Samadhi True Fire.

Although the volume of meteorite pure gold has shrunk, but it has become more pure and broken, at this time the meteorite pure gold is completely no longer as stone-like as before, the sun shines on it, black light, smooth, like a black pearl, pure, beautiful
