PS I originally wanted to make three more changes, take a look at the recommended votes...... I'm out of motivation, I'll see you tomorrow, I recommend voting, haha!

"This, is this copper?"

Looking at the purple-yellow copper block in Lin Feng's hand, all the clansmen gathered around, their eyes were full of curiosity, many people stretched out their hands as if they wanted to touch it, but they quietly retracted their hands halfway, and said in their hearts that it took so much effort to refine, what if it was broken?

"Let's take a look, it can't be broken!"

Lin Feng happily handed the copper block to Yang Zongshun and patted him on the shoulder, this copper block showed a faint purple color, which directly showed that the quality was very high, and there were very few impurities in it, if you use such a high-quality copper ore to refine the bronze, the hardness of the bronze will be extremely high!

Being able to smoothly refine copper for the first time, and refining such a high-quality copper, Yang Zongshun contributed a lot, if it weren't for his golden power, I don't know how much time it would take to refine it, let alone refine such a high-quality copper. Pen, fun, pavilion www. biquge。 info

"It's beautiful!"

"yes, yes, it doesn't look like a copper mine at all!"

The clansmen all looked around the copper and touched around, Yang Zongshun raised his head proudly, enjoying the admiring gaze of the clansmen, as long as he remembered what Lin Feng said just now, if he didn't have himself, it would be impossible to refine such a good copper, and his head would be raised a little higher.

In the past, he always felt that he was too old to be eliminated if he was useless to the clan that day, but now, he has fully proved his irreplaceable value.

Lin Feng estimated the weight, these copper blocks are about seven or eight kilograms, due to the current nature of accumulating experience, so the refining furnace is not very large, and the amount of mineral powder that can be added each time is only about one hundred kilograms, according to the quality of this copper ore, this copper yield rate can be regarded as very high.

"Patriarch, what's the use of this copper?"

"yes, yes, smash the monster like this? It doesn't seem to hurt any more than a stone......"

"It's softer than stone!"

Quan Chu, who was sweating all over, said, put it in his mouth and took a bite, and after making sure that the things refined in the stone were really inedible, he nodded and came to this conclusion, leaving a few shallow tooth marks on the copper mine.

"You bastard, bite everything in your mouth!"

Yang Zongshun was in a hurry, he jumped up and hit, and the treasure he had worked so hard to refine was bitten by the other party, and his angry lungs exploded.

"It's okay, Uncle Zongshun!"

Lin Feng laughed and said, "Don't you want to know what this copper is for?" You'll find out later...... Uncle Zong Shun, you continue to refine the next furnace of copper, and the others put down their work and follow me to make molds! ”

"Okay!"

Everyone happily agreed, but Chu Qing couldn't help Lin Lei on the refining stone, so he also came to make the mold.

The mold is made of clay from firing clay pots, and after breaking into long strips of mud, Lin Feng pressed out a model of a long sword with straight bamboo strips, which he has planned for a long time, after all, for him, he has been practicing the Flying Immortal Sword Technique, the long sword is indispensable, practicing with a wooden stick, the weight is not right, it is better to prepare a long sword in advance.

After getting his long sword done, Lin Feng pressed the specially fired pottery arrowhead in the clay embryo made by the clansmen, and also suppressed several short knives and other models.

As soon as she did this, Yuan Yuan had already trotted out and told Lin Feng that the ore in the second furnace had been refined and could produce copper!

"Tell Uncle Zong Shun to wait, I'll be there soon!"

Lin Feng hurriedly asked the clansmen to carry the molds they had made, and he rushed into the warehouse, and after estimating the weight of the copper juice, he took the tin ore powder with a bamboo tube.

Tin ore powder, which can be frozen into powder at low temperatures, is already very pure, but it eliminates the trouble of secondary refining.

"It's time to get out of the copper juice!" Lin Feng said.

"Let me come!"

Quan Chu, who was already eager to try, roared, followed Lin Feng's example, stabbed open the copper mouth with a wooden stick, and watched the red copper juice flow out, his face was full of accomplishment and looked at everyone triumphantly, if not everyone knew how much effort it took to refine this copper juice, I am afraid they would have thought that he was the only one.

"Get out of the way!"

Lin Feng asked everyone to retreat farther away, and then carefully poured the tin powder into the high-temperature copper juice and quickly stirred it with a wet wooden stick.

"Quick, pour this copper into the mold!"

Under his orders, Quan Chu hurriedly used soaked leather to pick up a container containing copper juice and poured it into the mold, Chu Qing's ice power was ready to be released, in case the hot copper juice splashed out and injured people, he could be treated immediately.

Copper juice is poured into the mold and gradually solidifies.

After a while, Lin Feng saw that the temperature had gradually stabilized, and only then did Chu Qing use the Ice Technique to cool down the bronzes in these molds.

Of course, he knew that the hardening of steel weapons would strengthen the hardness of the weapons after quenching, but this was bronze, he didn't dare to mess around, it took so much effort to cast such a little, don't be clever and make a whole pile of scrap, he has no place to cry.

The people of the Fire Bull Clan who went out to mine and Sun Wu Maotou and the others also came back, talking loudly outside, Lin Feng's eyes rolled, and everyone carried the mold to the small square, he wanted Tuoba and his people to also see the power of the new weapons he had refined.

"Patriarch, this is our clan's secret, how can we let the Fire Bull Clan know?"

Although it was only some semi-finished products, Yang Zongshun could still feel a bit of suppressed murderous aura from the shape of the long sword and short knife, and knew that this thing must be extraordinary, so he was worried.

"Don't worry, I'm in control!"

Lin Feng smiled and said, he was very sure that the Fire Bull Clan would take the initiative to merge into the Trojan Horse Clan after the mining mission was over, and showing these bronze weapons to the other party would also increase the confidence of the other party to take the initiative to join, but if Tuoba really didn't open his mind, he could only choose to kill those diehards among them, and the rest of the people would have to integrate if they didn't integrate at that time!

To put it bluntly, from the time when the Fire Ox Clan promised to come back with the Trojan Horse Clan, Lin Feng had no intention of letting the other party leave, so he didn't worry that the secret of the bronze artifact would be leaked by the other party.

What's more, even if these primitive people learned to refine copper ore, it would take a long, long time to cast qualified bronzes, after all, the ratio of copper and tin in bronzes is not so easy to experiment, if there are too many bronzes, they will be too brittle, if too little, the bronzes will be too soft, and the wear resistance is extremely poor.

He chose a short knife and handed it to Quan Chu, found a piece of fine sand and stone for him to polish Kaifeng, and looked at it with his own long sword.

The shape is very beautiful, the sword handle is moderately wide and narrow, the half-moon shaped swallow, even the blade to the hilt adds up to about two feet and five inches, and the weight is seven or eight catties, accounting for about half of a furnace of copper juice, although it must be a little difficult to wield it now, but Lin Feng believes that with the growth of strength, this long sword will be like an arm.

"Patriarch, the copper has already been refined, so fast?"

Sun Wumao smiled, while holding the short knives in his hands and looking around, as soon as he started his hand, he could feel a much lighter but harder texture than stone weapons, and one by one he was already excited and refused to let go.

"Patriarch Lin Feng, can you show me?"

Tuoba said cautiously, like Sun Wu and the others, as soon as he saw those bronze short knives, he couldn't take his eyes off it.

"Don't worry, Patriarch Tuoba!"

Lin Feng smiled slightly, pointed at Quan Chu and said, "These are still half-finished products, and only after they are opened, Patriarch Tuoba can you truly appreciate the power of these weapons!" ”
