Yan Zheng's request embarrassed Wu and the leader for a while, and they exchanged ideas with each other after they understood.

After the two reached an agreement, the leader pointed in the direction of the upper reaches of the river and described it with his hands.

Yan Zheng read from his body language that there was a cave in one place, but that place was a little far away.

Far away means danger, and they are afraid that something will go wrong.

Yan Zheng felt that it was better to be farther away, so that he might discover more along the way.

He also had the idea of investigating the surrounding areas of the tribe, as long as he understood the condition of the surrounding mineral plants, he could do more.

Staying in the tribe all the time can't be a big deal.

The leader and Wu quickly finished discussing, and they motioned to Yan Zheng that they could set off tomorrow after the sun rose.

Yan Zheng was a little happy, and then went back to his thatched house to prepare.

He first made himself a pair of rudimentary shoes out of animal skins and twine, which could not even be called shoes, but only footcloths.

Then he managed to make a pair of underpants out of sackcloth, which didn't look like panties, but he didn't have to walk the birds in the wild.

After doing these two things, Yan Zheng still felt that it was a bit rudimentary to go to the field like this, but he didn't have any better tools to use.

Only by accumulating technology in this tribe now can he reach a tipping point one day in the future and usher in an explosion of savage productivity.

At that time, he will be able to live a more comfortable life, at least in this life, and he will have to live a life that is not allowed in modern criminal law.

…………

Early the next morning, Yan Zheng was woken up by the noise of his clansmen.

When he walked out of the thatched hut, he found that the chief and the witch had gathered their people.

He found that almost the entire tribe had gathered in the tribal clearing.

It seems that the leader and Wu attach great importance to Yan Zheng's expedition.

Although they didn't know the purpose of this trip, with the benefits that Yan Zheng had brought a few times before, they had become more and more trusting of Yan Zheng.

Yan Zheng put on his underwear and shoes and walked to the front of the team.

The chief was also dressed to-day, with his beautiful hat with feathers and a necklace of bones around his neck.

After seeing Yan Zheng coming, the leader said a few words to the team.

Then the three big men standing at the front of the team stood beside Yan Zheng.

With the leader's order, the whole team began to set off.

What made Yan Zheng strange was that the leader would personally lead the team.

Moreover, the clansmen also brought a lot of animal skins and jerky, as well as the back basket that Yan Zheng asked to bring.

Although their weapons were all made of stone, each man carried a bow and arrow, a spear, and a stone axe.

It was almost like an expedition, with more men than they usually hunted.

Under the escort of these three big men, Yan Zheng followed behind the leader.

The leader took a spear and walked briskly.

Before he walked a few miles, Yan Zheng was a little overwhelmed.

Seeing this, a big man immediately bowed down and signaled that he could carry him.

Yan Zheng hesitated, but in order to better play his value, he accepted it calmly.

In this way, the big man carried Yan Zheng on his back, and he was still walking vigorously.

After walking about two miles, they entered a thick forest.

From a distance, the degree of black and dense trees in this forest once made Yan Zheng feel that this was a primeval forest.

"Stop!" Yan Zheng's eyes were attracted by a plant in the outer circle of the Black Forest.

He slipped off the big man's back, stopped the team, and rushed to the plant.

It's a wild Perran!

Yan Zheng laughed, Pei Lan's thing smelled fragrant, and the sex was flat and pungent.

In the absence of spices, this stuff is a good condiment.

Yan Zheng confirmed the location of this piece of Peilan, picked up the stone and circled it, and erected a branch next to it.

He planned to return to the tribe by the time he returned.

Seeing this, the leader came over and plucked a Perrin leaf and chewed it.

Since the political settlement of Yan, the leader is now very keen on herbal medicine.

Yan Zheng gestured: "When you come back, come here again to pick up the tribe!" ”

The leader nodded and continued to lead the group.

After entering the Black Forest, Yan Zheng only felt as if it was another world.

Only after his eyes have adjusted to the light inside can he take a closer look at the environment.

There are quite a few trails in the Black Forest, which seem to have been left behind by hunting.

And judging from the cries of wild beasts coming from time to time in the woods, there are a lot of wild beasts here.

Yan Zheng's first thought after walking in was to cut down all these trees.

This kind of black forest is really unsuitable for people, and there are humus layers everywhere.

Therefore, smoke miasma is rampant inside, and various microorganisms such as bacteria breed.

And judging from the humidity, this forest is not yet light.

Only chop chop chop!

This kind of forest becomes fertile land, which is the best destination, and in the era of barbarism, don't talk about protecting the environment.

After walking some way in the Black Forest, the leader stopped the procession, listened carefully to the movement in the woods, and then continued on his way.

The clansmen also began to maintain a high degree of vigilance, and they flashed their spears one after another.

"Stop!"

Yan Zheng's slightly surprised voice echoed in the forest again, and the leaders were startled.

I saw Yan Zheng excitedly running towards a puddle of brown slime, he loved cleanliness, so he actually dug it up and sniffed it.

Yan Zheng smiled at the pool of brown slime, which was a small pit that was not deep in water.

In this environment, a colony of rust bacteria can be formed, indicating that there is iron in this place.

In fact, iron is a very widespread thing, almost everywhere in the world.

The question is how rich the iron is, and colonies of iron bacteria can form on the surface of the earth, which means that iron-containing ores can be found in this place.

In the booklet of soil prospecting, there is a method to use the properties of iron bacteria to find iron ore.

Yan Zheng asked the people to dig up the brown slime and put it in the back basket.

And he asked the team to stop and let them all split their hands to find this similar slime.

The leader also tried to smell it, but nothing was famous.

After searching for about half an hour, the tribesmen found twenty-five places.

According to the distribution of iron colonies, Yan Zheng determined the direction to the southwest of the Black Forest, and iron was enriched.

So he carved a sign with a stone knife on the tree and led the team to the southwest.

Along the way, I collected a lot of iron bacteria soil, and the more I went, the color turned red.

In the end, Yan Zheng came to a small river, he sighed, and chose to return.

The stream is so disgusting, because it means that the place may have been alluvial a long time ago.

Therefore, iron ore may be buried deep under the surface, and it is difficult for savages to find iron ore under such conditions.

He made a sign along the way, planning to check it out next time.

"Stop!"

Before he took two steps back, Yan Zheng made a new discovery, and it was actually a few Xinyi.

This can not only be flavored, but also used in medicine!

Yan Zheng hurriedly made the mark, he felt that this trip was really worth it.

In this way, walking around the Black Forest, Yan Zheng obtained a total of eleven herbs, three of which could be used for flavoring.

And he also found a large number of mushrooms, but he didn't dare to covet the delicious taste of these mushrooms until he had to.

Because it is recorded in the 100,000 whys, when it is absolutely necessary, when you are about to starve to death, you can eat mushrooms in the wild.

And this is still in the case of being familiar with the types of mushrooms, and people who generally don't know the types of mushrooms go to eat mushrooms, and there is a high probability that they will get a result of eating the whole village.

By the time I walked out of the Black Forest, it was already afternoon.

The leader looked at the road ahead that suddenly opened up, but he made all the clansmen stop.

The three big men even surrounded Yan Zheng behind them, and it seemed that their vigilance was much higher than just now.

Just when Yan Zheng wanted to ask what was wrong, he suddenly noticed several figures in the distance.

He reacted violently, there are other tribes here!

As soon as he thought of headhunting, he instantly understood why the leader would prepare for this trip with such fanfare.

Yan Zheng suddenly became a little scared, this is no better than in the territory of the tribe, and now he is very likely to be in the territory of other savages.

The other savages didn't know that he had fallen from the sky.

"%¥#......" the leader said to a young man beside him.

After the young man saluted, he ran to the place where the figure had disappeared, and he was unarmed.

After about a quarter of an hour, the young man ran back.

After exchanging a few words with the chief, the chief sighed and asked a few of his tribesmen to carry out the hides and dried meat they had brought with him.

Yan Zheng looked confused,, the savages have also learned to collect tolls?
