The heating furnace in front of me is far smaller than the copper smelting furnace of the Wu tribe.

The Heat Bear inside only has a small pot of pot, and the churning is also churned with the red copper juice, which seems to be no difference.

A large group of people gathered around the heating furnace to watch. Several apprentices fanned their air and added firewood. After accumulating for a full six days, the temperature of the furnace fire finally reached enough to melt the copper ingots. In addition, the energy accumulated in the two metal juices of lead and tin, so the copper ingots in the crucible began to melt at a speed visible to the naked eye when they discovered that the copper inside began to melt.

With the continuous blowing of wind and firewood and continuous heat input, in just half an hour, all the copper ingots in the crucible melted and disappeared, and it turned into a pot of red and white metal soup. Through the observation hole in the furnace, it looked like the sun emitting a dazzling light.

"Quanhuaga!"

The kiln worker in charge of observation shouted in surprise.

"let me see!"

Xu Chen leaned over and took a look. He asked someone to pry open the furnace door closed with a tiled tiles, and put a long-handled pottery shovel in and gently stir it into the crucible for a few times. He found that it had indeed melted. So he instructed several smelter workers to quickly take all the mud molds of large and small made by themselves. After the tiles were combined, the surroundings were buried with sand and soil, and tightly clamped them with the tiles to prevent them from loosening.

After the row of more than ten mud molds were all placed, Xu Chen picked up a long-handled pottery spoon that had been prepared long ago, put on a thick animal skin apron, put on a skin glove, scoop out a large spoon of red metal juice from the crucible, and poured it into the mold.

As the hot copper juice poured into the mud mold, a thick smoke and a hot heat wave spread around it. Although it was still early spring and the temperature was still a little cold, under the high temperature of nearly a thousand degrees, everyone's faces changed color and retreated.

Long and his two companions looked at Xu Chen's movements without blinking.

The Wu tribe currently has four smelting furnaces, and copper is produced several times a month. They are common in this kind of high-temperature scene. However, the Wu tribe smelted all original copper, and there is no need to use this specially made fine mold. It only needs to be cast in a simple sand mold. The cast copper ingots are all copper pieces the size of a palm.

Therefore, the three of them were very confused about the process of Xu Chen pouring copper water into these mud sheets.

If I had known this, why didn’t I just use this mold to cast it directly when the Wu tribe produced copper? Why did I do this in one go?

Although Long doubted Xu Chen's actions in his heart, he did not dare to doubt his IQ.

In the end, I could only vaguely doubt Xu Chen was hiding any secrets and motives.

Just like Xu Chen didn't want to teach Wu tribe to spin and weave cloth at the beginning.

However, this idea disappeared without a trace just by a glance, and Long did not dare to continue to speculate and doubt.

Xu Chen's current status determines his powerful authority. He has long surpassed ordinary humans and even great witches and has become the supreme leader of all alliance tribes.

Therefore, any unreasonable suspicion will make people feel nervous and uneasy unconsciously.

Xu Chen didn't know that his actions had already allowed Long to see through his hidden motivation to make money alone.

At this moment, he was constantly scooping out the red and hot copper juice from the crucible and pouring it into a row of mud.

As the copper juice was poured in, the sand around the mud was steamed dry, emitting thick smoke and an extremely strong high temperature and anxiety. The heat waves of the entire pergola were rolling, and everyone began to sweat.

After spoonful after spoon, the copper juice in the crucible was slowly scooped dry, leaving only the last little bit left. The pottery spoon was powerless. Xu Chen asked someone to come with a long-handled golden spoon and scoop out the last copper juice into the last smallest mold.

"Okay, don't extinguish the fire!"

Although all the pouring is completed, it is not easy to heat up the furnace. You can continue to add copper lead-tin alloy to smel it. Therefore, Xu Chen asked not to anneale first. After verifying the quality of this batch of bronzes, you will fine-tune the formula of the three elements and perform the second smelting again.

A group of people were watching around a row of mud fields at this time.

Xu Chen was also very excited, and his eyes were slightly moist.

The fire of the dogs was too hot and their eyebrows were burnt.

After traveling through time for more than three years, I finally got eight dragon balls... Well, three elements created bronze ware.

Although the attributes of this bronze ware cannot be completely determined, he believes that the quality will not be too poor.

Taking off the animal skin coat, Xu Chen washed his face with cold water and then came over. He used a wooden stick to clear the sand around the first cast mud. With a hot breath of fireworks, the white mud that was also dry and white was revealed in the white mud that was smoked by the high temperature.

“Puff…”

Under Xu Chen's gentle tapping, the dry clay mud slowly broke and fell off, revealing a golden color inside.

"Wow, turn into gold!"

A kiln worker couldn't help but exclaim.

The remaining craftsmen were also confused.

Copper is purple-red, lead is black, and tin is silver-white.

After the three metals were mixed and melted, they turned golden yellow, which was almost exactly the same color as the gold accessories that everyone in the Ba people currently have.

In other words, Xu Chen refined three different metals into useless gold?

Long and the other three were even more confused.

Xu Chen was excited and mysteriously left them to witness this great miracle moment, but he didn't expect that he just refined copper into gold.

Although gold is very gorgeous and rare, the Great Witch's Scepter and the Golden Horn are decorated with gold wraps, with a very sacred temperament.

But there is no need. If you want gold, you can pick up a lot of gold every year near Yinlong Gorge of Cang clan. If Xu Chen wants it, why bother to work on the entire Wu clan to spend so much effort to refine copper? It would be great to dig gold near Yinlong Gorge directly.

Suddenly, the dragon felt that interest was gone.

So many people in the Wu tribe don’t bother to hunt and collect, and sometimes they even work hard to mine and smel, and it turns out that Xu Chen just wants to turn these copper into gold.

An inexplicable loss arose, and even his awe and admiration for Xu Chen showed signs of collapse in an instant.

All along, Xu Chen has always made innovative inventions that are very useful for production and life, but this time, Xu Chen's actions disappointed him very much. He felt that the hard work of so many people in the Wu tribe was completely worthless.

“Puff…”

Xu Chen didn't know the messy thoughts of a group of people, but continued to gently tap the mud, and slowly a yellow bronze axe without a handle was revealed.

This is a traditional axe with a square back of the arc and a hole in the middle. The structure is very simple.

However, although it has been dug out, the temperature is still very high, and the whole body is emitting a rolling heat wave.

Moreover, in order to ensure that the copper juice can be filled, there are some exhaust holes around it. In a circle of the axe, there are some metal burrs-like things, which look extremely weird in shape.

Xu Chen used a wooden stick to pass through the axe handle hole and picked up the hot axe and put it on a stone slab next to him. He asked someone to bring a stone axe and knocked down the metal burrs on it while it was hot. Then he picked up the axe and put it into a basin of cold water next to him.

"Puff~"

As a stream of hot mist soared into the air, the water in the pottery basin was chubby and rolled for a while and soon calmed down. Xu Chen gently tapped the water with his hand and found it was a bit hot, but he could still tolerate it. Therefore, he directly took out the golden bronze axe inside with his hands.

"His Majesty the Witch King, what's the use?"

Long finally couldn't help but ask in his depression.

"This is called an axe, which can be used to cut trees and wood, and it is much better than a stone axe!" Xu Chen explained with a smile.

The dragon's skin twitched slightly and said, "The gold is too soft, don't use it to cut down trees!"

"Haha, you're wrong. This is copper, not gold, but the color is indeed a bit like gold. If it's just gold, why should I let so many people spend so much effort to mine and smel? Big dog, go and get the handle of my axe!"

"Okay!"

A young and burly smelter immediately went to get things, returned for a moment, holding a pile of long and short wooden sticks on the ground.

Xu Chen picked a slightly curved long handle from it, gestured in front and behind the axe hole, then picked up the stone axe, and scraped it on a wooden stake next to it.

The axe handle was made from some dry wood after taking the free time a few days ago. There were more than ten large and small pieces, not only the axe handle, but also the knife handle.

However, these wooden handles have only been treated with a rough shape and have not been completely finished. After the knife and axe are cast, they have to be processed according to the actual object.

Xu Chen chewed and slashed, and the dragon and a group of people gathered around to watch.

The kiln factory casting was still quite loud, and the noise of the noise never stopped. At this time, many Ba people also ran from nearby to watch the fun. Just as Xu Chen was putting the axe handle on the axe, the little witch and Ye also ran over with a group of children.

Seeing the great witch arrive, the crowd quickly dispersed a path and respectfully welcomed the little witch to stand in the innermost part. The group of children also squeezed between the adult's legs and looked in curiously.

Soon, Xu Chen pressed the handle of the axe on it. After a series of impacts on a stone, the handle of the axe was firmly inserted into the axe hole. In order to stabilize it, Xu Chen chopped a small wooden wedge with the stone axe and gently nailed it between the axe handle and the axe hole.

After everything was done, Xu Chen raised the golden axe with tiny metal tumors on it, and a satisfied smile appeared on his face.
Chapter completed!
