Below the mountain behind the tribe, there is a huge stone building with a chimney above it, and thick black smoke is emitting.

"Class leader!"

With the arrival of Gu Chen, a group of people who were originally cheering in it saluted respectfully, and dozens of tribal people specialized in smelting black copper mines here.

Under Gu Chen's guidance and attempt, he finally successfully melted the black copper mine today, so he was naturally very happy.

In the smelting room, a huge furnace was built, a large furnace made of rock and clay, with a blower next to it.

Two burly tribal men were blowing the stove. In front of them was the furnace mouth, with some charcoal burning inside, and the temperature was extremely high.

In the furnace, several black copper ores were burning. Under the high temperature calcination, the black copper ores were deforming little by little, turning red, and there were signs of melting.

But Gu Chen found that the black copper ore still failed to melt, as if the temperature was not enough.

"Class leader, look, this is what we melted."

At this time, Black Soil came over with two metal blocks of different shapes and handed them over to Gu Chen.

He took it over and saw two metal blocks, shining with black and yellow copper. Yes, this is copper, it was really melted.

The black copper the size of a palm was heavy, with a little copper light. Gu Chen was surprised to find that these black copper were somewhat different from the copper smelted from modern times.

Because he felt that these black copper seemed a little different, and seemed to be harder and even more powerful than the copper on the earth.

"Very good, you guys did a good job."

Gu Chen was very satisfied. Although he failed to completely melt the black copper into copper water, this was a great progress and at least had a good start.

As long as you continue to explore and try in the future, the tribe will always truly master high-end smelting technology, and Gu Chen even has an idea in his mind.

That's bronze!

In this wild world, it is not clear whether there are tin ore and lead ore. If there are, it may be possible to smel out a more powerful thing, bronze.

Although the bronze smelting on the earth uses red copper, tin or lead ore to merge with each other to eventually form alloy and bronze.

But Gu Chen felt that this world should be able to synthesize bronze. As for whether there is red copper, black copper has been discovered now, so you may find a tin ore to try it.

If successful, it will be a great breakthrough and progress for tribal civilization and technology, and this is a symbol of civilization.

"Smelting, increase the temperature of the fire, I need to melt out copper water."

Gu Chen waved his hand and issued the latest order to increase the temperature of the fire and strive to melt the real copper water as soon as possible, so that he can create various things.

He continued: "Xiaohei, you immediately organize people and start preparing to build tools. First, it is a model of tools such as hammers. I will create model samples for you. Next is to build weapons and armor to strengthen the strength of our tribe."

"Yes, patriarch!"

Hei Tu had a respectful face and was full of admiration and admiration for Gu Chen.

Not only him, everyone present was extremely awe of the patriarch, and they completely regarded him as a god-like existence.

The tribe has changed greatly, and it changes every day, and all tribe members have reached a level of faith in the Guchen clan leader.

"Also, you have to leave the old tribe to do the things here. Your mission is to take the warriors of the tribe to practice, become stronger, and go to the back mountain waterfall to practice."

Gu Chen's face moved and he made a ruthless one, asking the tribe to form a legion of the strongest hunters selected by the tribe to practice under the waterfall on the mountain behind the tribe.

He has passed the Tianlang Moon Tendering Technique to other people in the tribe, and the cultivation effect is excellent. He practices Manniu Fist during the day and Moon Tendering Technique at night, absorbs the moonlight and tempers the body.

When the two are superimposed, the effect is simply amazing. In one month, the tribe's strength has undergone a huge change.

Now Gu Chen wants Hei Tu to take people to practice under the waterfall behind the tribe. Although everyone is shocked, no one has any complaints or objections.

For the entire tribe, the command of the patriarch is heaven, unconditional obedience.

After arranging the tribe's smelting and the cultivation matters, Gu Chen left here and explained it clearly and didn't have to worry about it.

He was thinking about a question, that is, the tribe has too few populations, and the tribe's population must be expanded in order to form a stronger team.

Where did the population come from? Gu Chen thought of the large mine of the Green-Skin Orcs, which not only had a huge and rich black copper mine, but also had tens of thousands or even more primitive tribal populations.

The tens of thousands of slaves there were all young and strong. Once rescued and integrated into the tribe, they would definitely be a powerful force.

Of course, the integration of tens of thousands of slaves will definitely have a huge impact. The first one is food. If there is not enough food, how can we support tens of thousands of people?

While walking back to the tribe from the back mountain smelting station, Gu Chen kept thinking about what to do next to rescue tens of thousands of slaves from the human tribe in the large mine?

"It seems that I have to plan a good plan."

As he thought about it, he suddenly sighed. With a conspiracy, he had to plan carefully to successfully rescue tens of thousands of human slaves who were enslaved and mined.

After all, there are tens of thousands of green-skinned orcs in the large mine. If you go rashly, you will definitely alarm the other party, and it will not be worth the loss.

"If they were drawn out and wiped out in batches, maybe there might be a chance?"

Gu Chen suddenly had his eyes lit up and thought of a way, which was to strangle the elite green-skinned orcs in batches.

However, if you want to complete the strangulation mission, you must have a strong team. After all, a person's strength is limited, unless Gu Chen's strength reaches the level of being able to destroy the ten thousand orc elite warriors with one person.

But it is impossible at present, because not to mention that a hundred people in the green-skinned orc have the strength of ten levels of body tempering and even the realm of Qi refining. Although their combat power is not as good as his, what about a hundred people?

He remembered that there were two terrible auras in the large mine, which gave him a sense of fear and danger, which was very dangerous.

Those two auras were very strong, and they were definitely strong people who had surpassed the bone-forging realm. They had to be careful, and Gu Chen was under pressure.

The two powerful green-skinned orcs who are in the large mine are likely to be two powerful people in the blood exchange realm.

"The blood exchange realm."

Gu Chen murmured to himself, a burning light appeared in his eyes. His strength was still too weak. He was just at the fourth level of the mortal body.

Although his power is stronger than the ordinary body tempering realm and even the bone calculating realm, the real blood-changing powerhouse is simply vulnerable.

"Continue to break through, break through at least to the tenth level of the mortal body."

Thinking of this, Gu Chen made a decision in his mind and continued to practice and make breakthroughs. At least he had to reach the tenth level of the mortal body to break through the bone-forging realm in order to have a little self-protection power.

He turned around and returned to the tribe, took things with him, rode on the white tiger and ran out of the tribe, wanting to go out to find some ferocious beasts to hunt, hone himself, and find some spiritual objects.

At the same time, in the tribe, Heizuo brought a thousand tribal warriors to the waterfall, and looked at the rumbling and falling violent waterfalls, which were extremely shocked.

"The patriarch said that being weak is a sin!"

"For the sake of the tribe, practice and become stronger!"

Black Soil roared, took off his animal leather jacket, and began a crazy self-abuse practice under the waterfall with a thousand people.
Chapter completed!
