And the seven brothers with embarrassed faces, after seeing Gu Zheng's smiling expression, immediately stood solemnly, revealing their strongest bodies to each other, intending to demonstrate in disguise.

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

The priest, who was smiling very foxy, took out a bundle of stone shovels from his back, beckoned to the brothers, pointed to a cracked ground under their feet, and beckoned: "Come, come, come, there are warriors of the Evil Clan, the time has come to contribute to the clan." ”

"Do you see the crystal clear glowing rocks beneath your feet?"

"For the sake of the tribe's tomorrow, dig it!"

After speaking, Gu Zheng handed them over one by one, still maintaining that bright smile, just waiting for the next move of the seven brothers.

But these seven, because they were born with Gu Zheng's aura, their first reaction was: You say dig it!

But Gu Zheng's next sentence immediately made this group of men dig down without raising their heads.

"This is a very important stone, if you do a good job, I can make you a 'dagger' that only the bravest warriors of the Fox Clan can have!"

With this phrase, let alone digging stones, just let them eat stones...... It's also to be obtained.

And these seven brothers are really worthy of the name of the most courageous warriors of the Youqi clan, don't look at the tools in their hands, they only dig twice and there is a precursor to collapse by this crystal golden sand vein.

But they can't stand it, this group of brothers is flexible and flexible, and they are very decent.

Led by the fierce giant, they began to think about it when they found that they had only knocked out a little scum when they went down with two stone shovels, and the crystal stone underneath had not moved at all.

And the solution they came up with is very simple, that is, dig it by hand.

I don't know if these people are too strong in the blood of their ancestors, those stones that are extremely solid in Gu Zheng's eyes, under the hands of the Seven Fierce Ones, they are as weak and deceitful as brittle wood slag, and as they go deeper, a shallow pit visible to the naked eye appeared in front of Gu Zheng.

As for the ore of various sizes that quickly piled up under his feet......

After Gu Zheng picked up a piece casually, the technology tree in the sea of his divine consciousness once again made a sound that was triggered.

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

"According to the law of energy conversion, the ratio of a piece of gold ore to a piece of chalcopyrite is 1:10, is it converted?"

Gu Zheng did not hesitate to order a yes.

The discovery of copper ore along the way is still unknown, and since there is something that can be replaced, why bother with the value of such things.

Besides, when they told primitive people how precious gold and crystal were, they couldn't understand it at all.

At this moment in a daze, Gu Zheng completed the conversion of pieces of ore, even if the 10/10 slot on the technology tree was full, Gu Zheng still didn't stop.

God knows when they will come across another mine, and this free labor will have to be put to good use.

Therefore, Gu Zheng's conversion was transferred to the collection team coming out of the woods, and the seven brothers who were trained by Gu Zheng to become dogs were in the bottomless pit, collapsed to the ground, and even had no strength to climb up by themselves.

As for now, under Gu Zheng's feet, only the crystals that absorbed the texture of golden sand remained, and with Gu Zheng's casual action, the pieces were broken into powder.

Hey?

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

These were a small number of crystal crystals that had not been fused with gold, and after being purified by Gu Zheng like this, they were purified from the original pitted ore.

This is a good thing, although Gu Zheng has not yet thought about what these crystals can do, but in this world, this kind of clear, beautiful and intoxicating ore will definitely have its meaning of existence.

Thinking of this, Gu Zheng was not ambiguous, beckoned in the direction of the return of the collection team, and summoned the two women who were not carrying things under the hands of the fox flower.

Then he took out the animal skin sac that he had prepared in advance, and then did not use it, pointed to the ore slag on the ground, and commanded: "Pick out the beautiful and complete stones inside, I will use them." ”

And after those women followed Gu Zheng's fingers and looked at the pile of tattered stone mines, they let out the cheers that women have used since ancient times when they see luxury goods.

"Whew!"

The sunset was long, and the pale yellow warm afterglow covered those white crystal beads, making them emit a kind of glow called gorgeous.

This is a boundless beauty that primitive people have never seen facing the trees and the loess in the sky, which hits the heart and shocks the soul.

Therefore, the screaming women didn't need Gu Zheng's instructions, they just scrambled to collect.

As for the seven brothers who managed to crawl out of the pit with great difficulty, they were smashed back to the bottom of the pit by the big basket full of saff fruit on their heads.

"Hideous one, two, three, four, five, six, seven...... Please!"

Help us carry the fruit back.

As for us, we have to pick up rocks.

Gu Zheng's unconscious move made the tribe, which had a dull atmosphere because of the long trek, once again full of laughter.

Those smiles that have not appeared for a long time have once again appeared on everyone's faces because of this small episode and the full load of food.

On the side, the Fierce Male Patriarch, who had always stood silently behind Gu Zheng, handed over a huge red tree fruit to Gu Zheng, who was also smiling, and after glancing at each other, they bit down at the same time with a very tacit 'click' and 'click' mouthful.

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

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

These fruit fruits, which were only slightly larger than eggs, were transported by the tribesmen, and they were carefully handed into their mouths as if they were looking at the rarest objects, and they were swallowed into their stomachs without even letting go of the kernels.

When the patriarch beside Gu Zheng was still unsatisfied and planned to do so, he hurriedly stopped him.

"Save some seeds, maybe you can plant them!"

Hearing this, the patriarch's eyes lit up, and when he looked again at the snarwood nuts that he was going to store and eat on the road, his eyes lit up as if he were looking at an inexhaustible granary.

As for Gu Zheng, after leaving that sentence, he returned to the garrison that had already built most of it.

As he expected, the priest's tent must have been one of the first structures to be erected during the migration of a tribe.

Not only that, but the animal skin bag that belonged to him was also placed on the side of the tent in a regular manner, and it looked like he was treated very seriously.

Gu Zheng, who was very satisfied with this, turned around and sealed his tent skin from the inside, sat down on the dry haystack and began to look through the current progress of the technology tree.

When the tech tree is opened again, the page belonging to the collection has been completely covered with white light, and it seems that it has met the requirements of the next branch of technology, and it can continue to upgrade.

In terms of the order of lighting the 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 you master the production of wheels, then the skills of the primary handicraft craftsman, Gu Zheng will also basically master.

The technology tree in the sea of divine consciousness seemed to clearly feel Gu Zheng's thoughts, and after Gu Zheng silently recited the wheel, a white light was automatically transmitted from the collected leaves, spreading along the branched branches, until it reached the top of the leaves representing the wheels, filling it completely.

And just after this 'collection' replenished the energy of the 'wheel', it once again returned to the appearance when Gu Zheng first discovered it, a bleak, inconspicuous gray state, and its original two options that were full of grooves also returned to zero again.

Oh, no, thanks to the Seven Brothers, it's still green and full behind the 10/10 groove of the ore.

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

Just after a general glance, Gu Zheng didn't pay too much attention, but put all his attention on the top of the wheel.

Wheels are clearly written on it (Wood 0/10)

As for why it didn't extend to other branches after it was activated?

Then Gu Zheng needs to research and find out by himself.

Gu Zheng, who had a headache, rubbed his head, for the first time he felt that he was still qualified to be a pretending criminal, but to be a technology man, he was still almost meaningful.

However, one thing he knew very well was that he had to collect the ten logs first, so he could prepare according to what would happen next to the tech tree.

Gu Zheng, who said he would do it, didn't work for a while, and collected ten pieces of wood that had been inspected by the technology tree from the hot construction point outside the tent, and then discharged them very carefully in the center of the tent.

And just when Gu Zheng finished all this, the blades that symbolized the wheels slowly stretched out.

In the space of the Sea of Divine Consciousness, a crystalline screen was activated.

One of the three-dimensional and multi-directional wooden wheels is slowly rolling in this picture, and next to the wheel, as it rolls, the production methods and tools of the wheels of primitive society are written line by line.

There was no other, a bone knife, a bone shovel, a bone awl, a rough frosted object, a bonfire, and a very dexterous pair of hands.
