Chapter 893

After seeing Gu Zheng's smiling expression, the seven brothers with an embarrassed face immediately stood solemnly, revealing their strongest bodies towards each other, and planned to demonstrate in disguise.

Who would have thought that they had completely misinterpreted Gu Zheng's original intention this time.

The priest, who smiled very fox, took out a bundle of stone flat shovels from behind, waved to their brothers, pointed to a cracked ground under their feet and said, "come, come, come, warriors of ferocious clan, it's time to make tribute for the clan."

"Do you see the Golden Rock in the transparency under your feet?"

"Dig for the tribe's tomorrow!"

With that, Gu Zheng handed it over one by one, still maintaining that brilliant smile, waiting for the next actions of the seven brothers.

But these seven, because of their natural discord with Gu Zheng, their first reaction was: dig as you say!

But Gu Zheng's next sentence immediately let the men dig without lifting their heads.

"This is a very important stone. If you do well, I can make you a 'dagger' that can only be owned by the bravest warrior in the fox clan!"

With this sentence, let alone dig stones, let them eat stones... Also want to get.

The seven brothers are worthy of the name of the most brave warriors. They do not have the tools to suck up their strength. Only two of them are able to be destroyed by the crystal gold mine.

But I can't stand it. These brothers are flexible and resourceful.

Still led by ferocious big, they began to think of their own way when they found that their two stone shovels went down, only knocked out some slag, and the crystal stone under them didn't move at all.

And the way they came up with is very simple, that is, dig well.

I don't know if the ancestral blood of these people is too strong. The strong stones in Gu Zheng's eyes are as weak and deceptive as brittle wood slag under the hands of the ferocious seven. With the deepening of their dog planing, a shallow pit visible to the naked eye appears in front of Gu Zheng.

As for the ores of different sizes piled up quickly under his feet

After Gu Zheng picked up a piece, he knew that the technology tree in the sea made a triggered sound again.

"Metal ore detected, gold content 25%, crystal 65%..."

"According to the law of energy conversion, the conversion ratio of a gold mine to a chalcopyrite is 1:10. Do you want to convert it?"

Gu Zheng did not hesitate to order a yes.

The discovery of copper mines along the way is still unknown. Since there is something that can be replaced, why bother about the value of this thing.

Besides, they have no way to understand how valuable gold and crystal are to primitive people.

In a daze, Gu Zheng completed the conversion of ore blocks. Even if the 1010 slot on the science and technology tree was full, Gu Zheng still didn't stop.

God knows when they will encounter another mine, and this free labor should make the best use of it.

Therefore, Gu Zheng's transformation turned to the collection team coming out of the yanmu forest, and the seven brothers trained by Gu Zheng into a dog collapsed to the ground in a bottomless pit, without even the strength to climb up.

As for now, under Gu Zheng's feet, there is only crystal that absorbs the texture of Jinsha. With Gu Zheng's action of throwing it away, pieces of it break into powder.

Eh?

Gu Zheng, who was ready to pat his ass and stand up to leave, found that there were some crystal beads and crystal leaves among the abandoned stones.

These are a small amount of crystal crystals that are not fused into gold. After being purified by Gu Zheng, they are purified from the original pitted ore.

This is a good thing. Although Gu Zheng has not thought about what these crystals can do, this transparent, beautiful and intoxicating ore must have its meaning in this world.

Thinking of Gu Zheng here, he was not vague. He waved in the direction of the return of the collection team, and summoned the two women who didn't carry anything under ferocious flower's hands.

Then he took out the animal skin bag he had prepared in advance and didn't have to use later. He pointed to the ore dregs on the ground and said, "pick out the beautiful and complete stones inside. I can use them."

The women followed Gu Zheng's fingers and looked into the pile of tattered stone mines. After that, they gave out the cheers that women have used since ancient times to see luxury goods.

"Ow!"

The sunset is long, and the light yellow warm afterglow is covered with those white crystal beads, making them emit a kind of light called gorgeous light.

This is a boundless beauty that the primitive people facing the trees and covered the sky with loess have never seen. It hits the heart and shocks the soul.

Therefore, the screaming women didn't need Gu Zheng's instructions, so they scrambled for the collection.

As for the seven brothers who managed to climb out of the pit, they were smashed back to the bottom of the pit by a big basket full of yam fruit.

"Ferocious big one two three four five six seven... Please!"

Help us carry the fruit back.

As for us? I have to pick up stones.

Gu Zheng's unconscious move once again filled the tribe with laughter because of the long journey.

Those smiles that haven't appeared for a long time also appear on everyone's face again because of this small episode and the full load of food.

On one side, the ferocious patriarch, who had always stood silently behind Gu Zheng, handed a large red Yan fruit to Gu Zheng, who was also smiling. After looking at each other, he bit it at the same time with a very tacit "click" and "click".

As Gu Zheng expected, the apple of the primitive era.

A little sour, a little astringent, a little tough, but more sweet.

These yam nuts, which were just a little bigger than eggs, were transported by the clan and carefully handed into their mouth like the most rare objects. Unexpectedly, they didn't even let go of the nuts and swallowed them into their stomach.

When the patriarch around Gu Zheng planned to do so, he quickly stopped him.

"Leave some seeds, maybe you can!"

Hearing this, the patriarch's eyes lit up. When he looked again at the Yamu fruits that he planned to store and eat on the road, his eyes were like looking at the inexhaustible granary.

As for Gu Zheng, after leaving that sentence, he returned to the garrison where more than half of it had been built.

As he expected, the priest's tent must be one of the first buildings built during the migration of a tribe.

Not only that, his animal skin bag was also placed on one side of the tent in good order, which was treated very seriously.

Satisfied with this, Gu Zheng turned around and sealed his tent skin from the inside. Sitting on a dry pile of withered grass, he began to look through the process of the current science and technology tree.

The science and technology tree opened again belongs to the collected page, which has been completely covered with white light. It seems to meet the requirements of the next branch of science and technology and can continue to be upgraded.

In terms of the lighting sequence of the science and technology tree, Gu Zheng did not hesitate to choose the option of the first wheel to be used.

This is a sign of the beginning of human mechanical technology. If he mastered the production of wheels, Gu Zheng would basically master the technology of primary handicraft craftsmen.

The science and technology tree in the divine knowledge sea seemed to clearly feel Gu Zheng's idea. After Gu Zheng silently recited the wheel, a white light automatically transmitted on the collected leaves and spread along the forked branches until it reached the top of the tree leaves representing the wheel and filled it completely.

After the "collection" replenished the energy to the "wheel", it returned to the dark and insignificant gray state when Gu Zheng first found it, and its original two options with full slots also returned to zero again.

Oh, no, thanks to the seven brothers, it is still green and full behind the 1010 slot strip of the ore.

It's just the wood. I'm afraid Gu Zheng needs to collect it again.

After a brief glance, Gu Zheng did not pay too much attention, but put all his mind on the wheel.

The wheel (wood 010) is clearly written on it

As for why it did not extend to other branches after it was activated?

Then Gu Zheng needs to study and find it himself.

Gu Zheng, who had a headache, rubbed his head. For the first time, he felt that he was qualified to be a pretender, but he was almost interested in being a science and technology man.

But one thing he knows very well is that he should collect the ten pieces of wood first, so that he can make preparations according to what will happen next in the science and technology tree.

After a while, Gu Zheng collected ten pieces of wood that passed the inspection of science and technology trees from the hot construction site outside the tent, and then carefully arranged them in the center of the tent.

When Gu Zheng finished all this, the blades symbolizing the wheel slowly stretched out,

In the space of divine knowledge sea, a crystal screen is activated.

One of the three-dimensional, three-dimensional and multi-directional wooden wheels rolls slowly in this picture, and next to the wheel, with its rolling, it writes the manufacturing methods and tools of wheels in primitive society in line by line.

Wuhe, bone knife, bone shovel, bone cone, coarse frosted utensils, a campfire, and a very dexterous pair of hands.
