Guo Yang has thirty knives in his hand.

Thirty knives shimmered in a large chunk of cyan rock, shining in the sun. Those lights are cold, making people's bones chill, and it seems that a slight wave can cut a river.

Anu felt like she was going blind. He looked at this and at that, and each one made his heart flutter.

"Anu, pick one yourself." Guo Yang reclined comfortably on a piece of animal skin, holding a round-footed beast face pattern (pronounced gu) in his left hand, which contained wine. Near the right-hand position, there is a crude bluestone case, on which is placed a small pot of charcoal, on which rests a bronze four-legged sheep's head Fang Hu (pronounced jia), scattering bursts of wine.

This wine is made by Anu himself, although it is not as good as the authentic nine grains brewed by the merchants, but it can be regarded as a good wine. After all, there are only three kinds of grain in the Grand Canyon: wheat, oats, and millet, and they can solve the food ration problem of hundreds of people. This time, the descendants of the merchants of the Grand Canyon had to reduce their rations for at least one month, and could only replace them with wild vegetables and other food.

Fortunately, Anu's breeding is very good, and he can find a way to solve the ration for one or two months.

"Young master, Anu is picky." Anu said a little depressed. He looked at any knife, it was all the best, but he could pick and choose, and he couldn't make up his mind.

"Man, what a slut!" Guo Yang took a sip of wine and said with a smile.

"What the young master said is that people are really cheap. However, cheap is not the same as cheap, hehe. Anu smiled heartily and began to pick out the knife again.

Guo Yang looked at Anu's serious appearance, and laughed a little, so he simply drank the wine in one go, lay down on his back, and watched the white clouds in the sky drift quietly by.

After three or four months of ironmaking, Guo Yang was a little tired.

Unlike the previous smelting of copper and tin, iron ore has too high requirements for fire and temperature, and the original smelting method cannot smelt iron at all. After wasting a lot of charcoal and burning seven or eight smelting furnaces, Guo Yang slowly found a little way.

He had Anu make five or six of them at a time, redesigning them so that a dozen people could take turns blowing the wind to ensure uninterrupted wind, which made the iron ore in the furnace turn into sap.

After raising the temperature, Guo Yang faced the problem of the purity of iron juice. The first few furnaces of iron juice are basically scrapped, covered with honeycomb-shaped holes, not to mention, black and not slippery, and there is no iron at all. Those scorched "iron slags", when smashed with stones, will shatter, and they are simply not as good as a piece of ice.

Guo Yang repeatedly studied and judged that this situation should be due to the insufficient purity of iron juice. He continued to use the catalytic method of ore powder when smelting bronze and brass, but it had little effect, but made the ugly charred iron slag even more ugly.

After trying more than a dozen kinds of ore powders, Guo Yang suddenly remembered that there were still some gray-white ore powders in his storage bag. With some hesitation, he added the gray ore powder to the furnace, and a surprising scene occurred.

The sap of the iron ore in the furnace was naturally separated after the addition of gray-white mineral powder. The upper layer of red iron juice flowed out of the furnace and condensed into a kind of charred iron slag, while the layer of iron liquid below it showed a strange flocculent, which made Guo Yang stunned.

When the furnace fire was a little weaker, and the flocculent iron piece was clamped out from the furnace, Guo Yang couldn't cry or laugh a little. He tried to forge it, and after repeated heating and cooling, some black impurities precipitated from the iron, showing an indescribable white.

Guo Yang thought of a lot of ways, but always felt that the kind of iron he had refined was wrong, either it was too soft or too hard, and it couldn't be made into a knife at all.

After repeatedly referring to the refining method left to him by the mysterious old man, Guo Yang tried to mix some copper powder, tin powder, etc. into iron and forge it, and the effect improved slightly, but it still did not have the feeling of the knife in his hand.

A fortuitous event changed Guo Yang's iron.

One day, Guo Yang was really depressed, so he simply threw two pieces of iron that had been beaten very thinly into the fire, intending to take a break and forge again. When he finished drinking the water, he found that the two pieces of iron were about to merge in the fire, so he simply clamped them out and commanded Anu to hammer them all around.

An accident occurred, and after the two pieces of iron were forged at high temperature and cooled by cold water several times, they showed an unprecedented sense of toughness!

What is particularly strange is that the fused iron piece, after repeated folding, forging and cooling, actually presents a form similar to fine fish scales, and its quality seems to be higher than Guo Yang's knife.

Guo Yang was ecstatic, began to take charge of the hammer himself, and used all his strength, and finally hit the first knife three days later.

The next step is relatively simple, Guo Yang finally mastered the core technology of ironmaking after carefully consulting the whole process.

The first batch of thirty knives was built, and Guo Yang had an idea.

Among the descendants of merchants in the Grand Canyon of Wuling Mountain, there are thirty children who are suitable for practicing martial arts, and with the addition of Anu, that is thirty-one. Guo Yang didn't want these people to continue to be obedient sheep, he had to make these people strong.

The frequent wars, the endless raids of the Zhou people, the harassment of the homeless bandits, and the threat of those wild beasts all made Guo Yang determined to let the descendants of these merchants start to practice martial arts. Even, if possible, he wanted to pick one or two children who could cultivate and start practicing the authentic cultivation method.

At this moment, looking at Anu's embarrassed appearance, Guo Yang showed a rare smile.

"Anu, have you picked it out? If I don't pick one, I'll distribute it all to others. Guo Yang said with a smile.

"Young master, do you want to ...... You can help me pick one, I really can't choose, I think each one is good. Anu scratched the back of her head and said embarrassedly.

"Haha, Anu, don't bother, there is no you in these knives." Guo Yang said.

"Huh? The young master ...... "Anu was in a hurry, so he grabbed a knife directly, and planned not to let go."

"Which one are you really going to pick?" Guo Yang slowly stood up, stretched his waist, and asked with a smile.

"Young master......" Anu was a little puzzled.

"I was still thinking of returning this one of mine to the furnace and using a new smelting technique to rebuild two better knives, and now that you already have it, you won't have to bother anymore." Guo Yang said lightly.

When Anu heard this, he was stunned for a moment, put the knife in his hand back, and shouted twenty or thirty children, holding charcoal, moving ore, and pressing, and they were busy all of a sudden.

Guo Yang shook his head with a wry smile and said, "Anu, don't be so anxious. ”

Anu smiled and didn't speak, but his subordinates were full of energy, and he and a group of children were in full swing.

……

Three days later, the two new knives were born.

At that moment, torrential rain fell from the sky, lightning and thunder, and it seemed that they were also cheering for the two knives.

Legend has it that several bolts of lightning struck the two freshly baked knives, leaving a trail on the black and white knives covered in finely crushed fish scales. From then on, every time those two knives were unsheathed, there would be a faint thunderclap.

As for the authenticity of this legend, it is too long to verify. But there is a fact, that is, the moment the new knife was baked, Guo Yang suddenly heard a groaning sound, simple and mysterious, faint.

To this, he remained silent.

Wuling Mountain, the Grand Canyon, with thirty-two knives.
