Guo Yang and Anu came to an inconspicuous mountain peak and planned to go to the field to investigate.

The mountain is not high, but there is a stream of considerable water, which flows in a hurry. On both sides of the stream, a thick layer of dark red stones is paved, and the stream is a little dark red.

Guo Yang pinched up a stone, carefully discerned it against the sunlight, and found that it was indeed a metal mine, and it seemed to be of better quality than bronze.

The two of them followed the stream all the way into the mountains, but it was a narrow canyon full of that dark red ore. As for the vertiginous cyan ore, Anu said he found it in a cave.

"Young Master, can this red stone be refined into metal?" Anu also held a red stone, followed Guo Yang's example, and looked at the sun repeatedly.

"Hmm." Guo Yang agreed a little absentmindedly, and took out a roll of bamboo slips from his arms, but it was the set of purification methods left to him by the mysterious old man.

Guo Yang has never stopped referring to this set of purification methods, but he has always been puzzled. When he was surveying these dark red stones just now, he had a whim, and vaguely felt that the method of purification seemed to be not just to purify a certain thing, but a concept, or a theory.

"Perhaps, a new method of refining." Guo Yang sat down on the stone, his eyebrows furrowed, and he fell into a wonderful hypothesis.

Anu looked at Guo Yang's appearance, walked away with interest, picked up a stone from time to time, and observed carefully.

After a long time, Guo Yang's frowning brows finally relaxed, he stood up briskly, and shouted loudly: "Anu, I figured it out!" ”

Anu also ran over with an excited face and bowed down to say hello.

"No matter what metal ore it is, let's find a way to refine it first, haha, I always thought about this set of smelting methods and that set of smelting methods before, and it will be clear if we start refining it!" Guo Yang suddenly figured out this layer and felt extremely comfortable.

I can't figure it out, it's better to practice, smelt more and purify, and you will know everything!

Guo Yang looked east and west in the canyon, knocking down one or two pieces of that dark red ore from time to time and putting them into the storage bag.

In addition to this dark red ore, Guo Yang also found a pale gray ore on a cliff wall. The amount of this pale gray ore is not large, but it feels very peculiar, because Guo Yang was surprised to find that in the area where the gray ore is distributed, the metallic luster of those dark red ores seems to be much clearer.

Guo Yang knocked down a pile of pale gray ore with stones, and put it away in a storage bag alone, intending to take it back and study it slowly.

In addition, in a very shallow cave, Guo Yang also found a large piece of black ore, the texture is very hard, and it seems to contain some kind of strange power, which can actually attract his knife!

This had never happened before, and as he approached the ore, the knife at his waist trembled slightly with attraction, and seemed to be about to come out of its sheath. This surprised Guo Yang, and quickly reached out and held down the knife.

Feeling the wonderful feeling for a while, Guo Yang simply took out the knife and slowly approached the swarthy piece of ore.

The unthinkable happened!

There was a soft "snap", and the knife was sucked away by the ore and clung to it. Guo Yang reached for the knife and felt a rather strong absorbing force.

The corners of Guo Yang's eyes twitched twice, his eyes widened, and he carefully examined the piece of ore, and found that this piece of ore was not black except for its particularly hard texture, and it was not inconspicuous at all.

Guo Yang was very interested, called Anu for help, beat it with sharp stones, and found a few thick logs to pry it, and it took a lot of effort to get the huge stone out of the cave.

When the huge black stone rolled down, an amazing scene occurred.

Those dark red ores, as well as a dark cyan ore, were actually attracted by the black stone, and they flew up in the air one after another, shooting towards the black stone. By the time the boulder reached the bottom of the canyon, it had become a behemoth that had grown three or four people tall because it had attracted so many fist-sized ores along the way.

Looking at this amazing scene, Guo Yang and Anu opened their mouths wide and couldn't close them for a long time.

"Young Master...... This is the Divine Stone! After a long while, Anu muttered.

"Divine Stone? It seems to be kind of interesting. But ......," Guo Yang said, cautiously approaching the behemoth.

Looking at the dense dark red ore in front of him, Guo Yang cautiously stretched out his hand and removed a small piece of it. A strange force of attraction appeared again, like ...... Remove the knife from the black stone.

"It's ...... Iron! Guo Yang screamed suddenly, startling Anu a lot.

"Iron?" Anu asked, confused.

"Anu, we're going to get rich! It's iron ore! Iron, the kind of iron of a knife! Guo Yang slapped Anu on the shoulder hard, and directly slapped the sturdy man to the ground, grinning for a long time before slowly getting up.

"Young master, when you pat me in the future, you have too much strength...... Anu said with a bitter face, reaching out and caressing Guo Yang's shoulder, with a painful face.

Guo Yang turned his head to look at Anu's appearance, grinned embarrassedly, and said apologetically: "Anu, I'm sorry, I'm so happy, I missed slapping you." ”

"Young master, are these really iron ore?" Anu endured the huge pain in his shoulder and asked in surprise.

"Well, it's iron ore! Originally, I thought that iron could only be refined in meteorites. Because, according to old legends, iron is a divine stone outside the sky, and only those who have access to heaven can obtain it by chance. From this point of view, in addition to the Heavenly Divine Stone, there is actually iron on the earth! ”

Guo Yang pinched a piece of dark red ore, and was a little carried away with excitement.

"Young master, isn't iron white? How is this stone red? Anu was a little unconvinced. In his mind, copper ore should be golden and dark green, because copper is golden and rusty and green.

But this dark red stone ...... In any case, he could not connect with the snow-white knife.

"Pure iron is white." Guo Yang suddenly remembered his father Guo Lu, the tall man, and couldn't help but moisten his eyes.

"If it's really iron ore, that's great, I can have a knife too!" Anu followed Guo Yang's example, pinched up a piece of ore, and his face was full of smiles.

Looking at Anu's appearance, Guo Yang smiled: "Anu, do you really want a knife?" ”

"Yes, I've always dreamed of having a knife like yours!" Anu laughed.

"Okay, then you're busy. I'll give you the task of taking the stronger kids and going to burn a batch of charcoal first. In addition, a 橐 (pronounced tuo) is also needed, and iron ore refining is definitely more difficult than copper ore refining, and various preparations must be made. Guo Yang said.

"Huh? What is it? Anu was a little confused, he had never heard of this thing.

"Ahem...... Intensify the fire when smelting ore. Guo Yang took out a carbon rod and drew a sketch of the coffin directly on Anu's animal skin skirt.

"So that's it, isn't this a bellow!" Anu suddenly realized and smiled.

"Bladders? Have you seen it? Guo Yang asked in surprise.

"Yes, we have one of our high priests." Anu laughed.

"What does the high priest want to do? Could it be that he knows the method of smelting? Guo Yang was a little confused, he thought that those high priests were all people who had mastered the art of ghosts and witches, and they had nothing to do with smelting.

"I don't know, but I've seen the one you said anyway. In our Diren tribe, it is called a windbag. Anu said.
