Hearing the teacher's call, Hua came in a hurry with a happy face.

He came with a beautiful fantasy, full of joy and thought that the teacher had something good, and thought of him, and the result was ......

"I'm the King of the Golden Winged Roc, you...... You actually asked me to come out with you to dig in the mud?" the golden-winged roc stomped his feet angrily, gritting his teeth.

Lin Xiuwen glanced at him, pursed his lips, and said, "What are you talking about. Do you dig or not?"

"Dig, dig, boss, I'll dig. King Golden-winged Dapeng hurriedly curryed favor with Lin Xiuwen and said with a flattering smile. But in my heart, I was full of slander.

This big demon king who suffered a thousand knives actually asked me to dig in the mud, and I didn't let it go.

"What do you see, why don't you come and dig with me, can you afford to delay my boss's affairs?"

The two of them dug up the dirt.

After digging for a long time, Lin Xiuwen didn't see what he wanted, shook his head, and took the two of them to another place to continue digging.

King Hehua of the Golden-winged Dapeng dug for a long time, and looked at Lin Xiuwen with blank eyes.

Lin Xiuwen shook his head, still no.

Keep changing, keep digging.

......

Lin Xiuwen's eyes lit up when he saw the newly unearthed soil of the two.

"That's it. Lin Xiuwen laughed.

Clay.

Raw materials for making pottery.

Its discovery meant that the bear tribe could go directly into the pottery age.

King and Hua of the Golden-Winged Roc breathed a sigh of relief, and there was no need to dig mud everywhere. The two looked at each other, and they actually felt a little sympathy for each other.

"Why are you still stunned, hurry up and dig up, if you want this kind of soil, the more the better. Lin Xiuwen was a little excited and urged them.

The Golden-winged Dapeng King and Hua were instantly deflated, looking like they had nothing to love.

......

The discovery of clay made the bear tribe successfully enter the pottery age under the leadership of Lin Xiuwen.

In the inner clearing of the tribe, a large amount of clay has also been successfully excavated.

Within the bear tribe, a trend gradually formed, a new fashion of firing pottery.

For Lin Xiuwen, bringing the tribe into the pottery age was only incidental, and his main purpose was not in this.

In the courtyard, Lin Xiuwen looked at the complete set of pottery in front of him, and a bright color flashed in his eyes.

It is a large furnace made entirely of pottery.

What does a person do when he has a large amount of copper, lead, and tin ore and has a reactor?

Smelting metals.

The overwhelming wildfires not only expelled the monsters and birds of prey, but also burned a lot of metal copper elements. The red copper metal is a treasure that nature has given to mankind. Throughout the course of human development on the whole earth, bronze is the first large-scale and widespread use of metal by human beings. It can even be said that it opened the era of cold weapon warfare for mankind.

Lin Xiuwen naturally didn't want to miss such a great opportunity to help the development of the human race. In fact, Lin Xiuwen still has some doubts. He had already discovered that in fact, there were still some primitive human tribes in this wild world, but they did not develop as fast as the poor tribes.

Since a poor tribe met him, it was also a chance. Naturally, of course, he was willing to help him. What's more, to promote the evolution of primitive human civilization, which is also what he expects.

As long as there are poor tribes who have bronzes, they have the opportunity. The rules of war, or the rules of war of mankind in the age of cold weapons, have always been that civilization conquers the wilderness and civilization rules backward. In this way, the poor tribes can lead all the way.

Lin Xiuwen played with a piece of red copper in his hand, kneaded it casually, and shook his head.

The day after the fire was extinguished, he sent poor tribes all over the world to search for the red copper that had been smelted by the fire.

Xia stood beside him, also holding a piece of red copper in his hand, looking left and right, looking puzzled.

"What are you doing with those soft things?" the Golden-Winged Roc King muttered quietly. He was also inexplicable, and he didn't know what Lin Xiuwen's soft stuff was for. Although the thing was shiny, what could a soft person do?

The reason why pure copper was not directly used in ancient times on the earth must be because the hardness of copper was not enough. Lin Xiuwen nodded, knowing in his heart.

"I'm going to have to get the bronze. ”

Pure copper is reddish, metallic, and dense, but it is soft and usually cannot be used directly. However, as long as a certain proportion of other metals are mixed into pure copper, such as lead metal or tin metal, and it is turned into a metal mixture, the physical properties of the elemental metal can be greatly changed, and a light and hard metal mixture can be obtained.

This is bronze.

"Xia, you go find a few tribal elites to come over. Lin Xiuwen shook the copper block in his hand, turned his head, and said to Xia.

Xia Xingli turned around and was about to leave. But soon, he went and returned, bringing with him a group of people.

At noon, a group of elites gathered in Lin Xiuwen's small courtyard. The group of people who are pressed by the black pressure are all old, but they can't see it on the surface.

Being able to approach God's dwelling, of course, they don't want their juniors to do it for them. Everyone, with a smile on their faces, flatteringly gathered in front of the pottery alchemy furnace.

A large amount of charcoal is piled up around the pottery furnace.

Making charcoal is also a skill that Lin Xiuwen has for poor tribes to spend the winter. The tribe cut down too many trees, so Lin Xiuwen simply taught them how to make charcoal.

At this time, it was used for alchemy, but it was just in time.

The pottery alchemy furnace billowed up with gray-white smoke. The Golden-Winged Roc King was aggrieved and carefully added charcoal to the pottery furnace, and the light of the fire in the furnace turned his face red.

Alas, in this era, it's hard to be a demon. The Golden-winged Dapeng King occasionally raised his head, looked at a large circle of poor people around him, and then looked at Lin Xiuwen, looking like he wanted to say something.

Lin Xiuwen's face was expressionless, just quietly looking at the alchemy furnace.

Seeing this, the Golden-winged Dapeng King suddenly lost his temper, so he could only swallow his saliva and swallow the words into his stomach.

Lin Xiuwen shook his head and motioned for a clansman to take over the King of the Golden Winged Dapeng.

The clansman who was shown was also interested, and took over the golden-winged Dapeng king with a happy face. He knew very well that this Golden-winged Roc King was a person beside God, and he had always been mysterious, and it was an honor to be able to succeed him.

The King of the Golden Winged Roc nodded at him, looking like you kid is very good.

Lin Xiuwen didn't care about this, and calmly commanded the man to operate the blast furnace. That person is not stupid, and the matter is also simple, and nothing went wrong.

The red blast furnace emitted a large amount of heat, and even the people who stood farther away could feel its scorching heat. It's like being scorched.

Lin Xiuwen was expressionless and waited quietly. Hua shook the blower in front of him, even though he, as the patriarch, would not know that another thing of great epoch-making significance to the human race was about to be born.

On the earth, the melting point of pure copper should be 1,084.62 degrees Celsius, and Lin Xiuwen didn't know that it was exactly the same from time to time here.

Probably not very far behind, Lin Xiuwen believes.

There are actually some difficulties in reaching this temperature. As long as the heat can be high, it must be able to rise to 1,000 degrees. Perhaps, there are 1,000 degrees Celsius, Lin Xiuwen felt the scorching heat, and he guessed that the temperature might reach 1,000 degrees Celsius.

Perhaps, the red copper is about to melt.

"What's that?" suddenly shouted one of the clansmen.

The crowd looked at him.

Lin Xiuwen was the first to see it. Drops of liquid fall from the bottom of the furnace.

The liquid was like mercury, with a dazzling sheen, red and red. It flows down a semicircular tube and collects into a pottery vessel.

Lin Xiuwen exhaled softly, and it seemed that he had succeeded.

In the pottery container, the liquid metal liquid was smashed into pits by metal droplets, rippling and rippling, and then calm was restored.

It is a pure copper metal melting liquid.

"Add tin. Lin Xiuwen's face was expressionless, and he explained to Hua.

Xia looked at Lin Xiuwen with a blank face.

Lin Xiuwen's face was expressionless, and he turned his head to look at the Golden-Winged Dapeng King.

Seeing his eyes, the Golden-winged Dapeng King said a word of hemp wheat skin in his heart, and hurried to the back of the pottery alchemy furnace. There is also a smaller secondary furnace on the back of the furnace, which shares the thermal energy of the main furnace.

A silvery-white droplet flowed down from the side of the sub-alchemy furnace and was channeled through a semicircular tube into another pottery vessel.

The Golden-Winged Roc King picked up a pottery spoon from the side, floated out a small half spoonful of metal liquid from the pottery container, and walked quickly back to the main furnace.

The tribesmen of the poor tribe looked at the silvery molten liquid in the pottery spoon, and then at the red copper molten liquid flowing from the red metallic luster in the pottery vessel.

You look at me, I look at you, with a confused face.

Lin Xiuwen took the pottery spoon from the hands of the Golden-winged Dapeng King, and the tin metal molten liquid in it exuded a beautiful silvery-white luster, which formed an incomparably sharp contrast with the red metal copper molten liquid.

He frowned. He knew exactly how to refine this bronze, but he was not sure how much other metals would be mixed in.

Exhale softly, let it be fate, Lin Xiuwen said secretly in his heart.

Xia didn't know that his teacher had fallen into an embarrassing situation, and looked at Lin Xiuwen with a curious expression, wanting to witness the miracle.

The teacher is always right. Teachers can do anything. The teacher knows everything. This is his logic.

Lin Xiuwen casually poured a small half spoonful of tin metal molten liquid into the red copper molten liquid and handed the spoon to the Golden Winged Dapeng King. Stir gently with a ceramic stirring stick until it feels almost even.

"Wow, look, look, the color has changed. Someone exclaimed.

Everyone else was also staring closely at the molten liquid in the container, watching the color of the molten liquid in the container continue to change, and the cultivation turned into a brown solution. I was extremely surprised in my heart, and the scene instantly became a little noisy, and everyone turned their heads to each other.

Lin Xiuwen didn't care about them, and poured the metal mixture into the pre-prepared pottery mold after stirring by himself.

He made a total of three molds.

After filling up the three metals, Lin Xiuwen stood there quietly.

The others also quickly quieted down, looked at Lin Xiuwen with some weak hearts, and looked at each other.

Leaving the heat source, the molten metal cools rapidly at room temperature, gradually solidifies, and takes on a tan color.
