With Xu Chen's continuous innovation and invention, the division of labor of the tribe has also begun to undergo new changes.

With the vine basket, the food collected increased a lot, and the sorting and drying began to require a large number of people. Therefore, a group of women was divided into three teams, one team was responsible for collecting, one team was responsible for drying, and the other team was responsible for taking care of the elderly and the weak.

The same is true for men, with clear different divisions of labor. One team was responsible for hunting and was once responsible for specializing in the production of bow and arrow weapons.

Because of the emergence of pottery, Mu Ba arranged two adult men to be Xu Chen's assistants to build a fire kiln at the foot of the mountain.

Division of labor and cooperation is a typical way of survival for social animals.

The more division of labor, the more complex the social attributes will be and the stronger the ability to survive.

Before we knew it, the tribe's manpower became increasingly stretched.

In the next two days, Xu Chen took Gu Heju, and two men who were injured and weak and were not suitable for hunting went out early and returned late. Finally, he dug a large pit with a diameter of three meters at the foot of the mountain.

Next, you can pick up stones and mud to build a fire kiln.

But at this time Xu Chen realized that the problem was coming.

There are very few stones at the foot of the mountain, so I can only pick them up on the river beach a few hundred meters away.

In addition, if you want to mix mud, you have to get water, and you can only go to the river to get it.

But a bigger problem has come again, no tools to get water.

The stone is fine, but you can use a basket without a cart or a basket, or even hold it with your hands. At most, you can go back and forth a few more trips, but getting water is really troublesome. The only thing the tribe members can use to hold water is a clam shell, but only enough to drink a few sips. If you want to get mud, it is a drop in the bucket.

what to do?

Xu Chen could only communicate with a few companions in a row.

After figuring out Xu Chen’s needs, someone pointed to the valley on the side and gestured a big move: “Ye Ga.”

Xu Chen's face was full of surprise.

He was not talking about the girl's leaves on the mountain, but refers to the fact that there is a large leaf in the valley that can be used to hold water, so two men were left to pick up stones on the river beach. Xu Chen took Gu Heju and set out with a spear and a bow.

The valley is on the south side of the mountain, just below the large piece of milk fruit on the side of the mountain, but it takes nearly two miles to pass.

If it were before, three young men who had no experience in survival in the wild would never dare to go, but the wolves in the valley have been killed, the head wolf died, and the wolf den was held. The remaining wild wolves could not continue to live here.

In the territory where wolves live, there are generally no other large beasts.

Therefore, the valley is relatively safe at present.

The three of them walked around the foot of the mountain along the path where hunters usually traveled, and then arrived at the entrance of the valley twenty minutes later.

There are cliffs on both sides of the valley, covered with ancient trees and vines, and monkeys are jumping and playing on it. In the valley, in addition to dense large stones and clear streams, various tall aquatic plants and plants are grown on both sides. One of them is a plant similar to taro, with thick stems, larger leaves than people, and purple patterns on the leaves. Some have a tall fruit ear in the center, with the tops expanding into a spherical shape, purple-red color, like a big dick more than a meter long, which makes people feel ashamed of it.

The whole valley is dark and humid, like being in a tropical rainforest.

Xu Chen jumped on the big rock among the stream to a huge taro, reached out and pulled the wide leaves, and found that they were very strong and difficult to break off. However, just when he was about to use brute force, he was stopped by Gu Heju and others.

He raised his spear in his hand and stabbed a hole in the petiole. In an instant, a light red liquid emerged, and soon condensed into a transparent substance like jelly.

"Dog!"

Gu pointed at Jelly and reminded him seriously.

Xu Chen's face calmed down instantly.

Poison means poisonous and its pronunciation is extremely accurate.

In other words, this taro-like large-leaf plant is poisonous, not only poisonous, but also cautious and serious attitude of the two, it should be quite toxic.

And based on his previous life experience, this is also reasonable.

All taro-like plants in nature are basically poisonous, including taro.

Some people are allergic to taro, and if they come into contact with it when peeling, their skin will be extremely itchy.

Similar plants such as common konjac, Pinellia ternata, and Drop Water Guanyin are poisonous, regardless of roots, stems, leaves and fruits, and similar plants are especially common in tropical rainforests.

Human beings are constantly exploring the world in the long evolution, and the legendary figures like Shennong are actually the collection of countless human ancestors in the process of understanding nature and leading human beings to the development of agricultural civilization.

In order to commemorate these ancestors, humans have turned these myths of sages into characters from generation to generation, and then worshipped them.

This huge taro-like plant in front of me is close to a group of primitive people, so it should be clearer about its characteristics.

Moreover, this jelly-like juice is definitely not an ordinary poison. According to the rough skin of a group of savages and their calloused hands, they almost don't care about the ordinary poison.

Therefore, I guess this juice cannot be touched.

So Xu Chen was instantly deflated, and even said something about poisonous.

Seeing Xu Chen retreating with depression on his face, Gu took out a stone knife from his back basket, leaned it up and carefully cut off the petiole, and then immersed the petiole into the stream and continuously washed it.

A few minutes later, he lifted the petiole up to watch and found that there was no juice oozing out. Then he smiled and gestured, saying that this would be useful.

Next, Gu made the same move, cut several huge leaves one after another, soaked the juice in the stream water to wash it clean, and then the three of them carried it back like a banana fan.

After working hard for more than an hour, when they returned to the foot of the mountain, the two men had already picked up a pile of stones in vine baskets.

Next, he was responsible for carrying water with the basket that was padded with this big leaves, Gu was responsible for digging soil and mud, and Xu Chen was responsible for building the earthen kiln with a bone knife.

When they were so busy that they were hungry, a group of people went to the river beach to catch fish and then came back to make slate roasts.

A single operation is as fierce as a tiger, and his work performance is 25 years old.

Five people were busy eating and playing until the sun was about to set. When the men who went out to hunt returned to the mountain, Xu Chen and the other two built a kiln bottom less than two feet high.

In the next few days, Xu Chen led this four-person construction team to go out early and come back late. He spent six days to finally complete the first pottery kiln in human history.

This is a huge artificial miracle.

It is more than three meters high and is incompatible with the wild natural environment around it.

The overall structure is similar to the small fire stove on the mountain, but it is magnified dozens of times.

Below is the furnace, which is made of stone into a ditch, and the inner layer is built into an annular step-shaped step-shaped, gradually closing the mouth to form a conical space with a width at the bottom and a narrow upper part.

The inner walls are smoothed with wet mud, and there is a vertical flue connected to the furnace at the bottom. The spaces around the outside are refilled with the digging soil and stepped firmly, looking like a cave.

As the Kong kiln was gradually taking shape, everyone was completely shocked by Xu Chen's big creation ability.

Not only Moba and a group of women, but also Feng and a group of men responsible for hunting, they no longer collected food and hunted, and they ran to watch in groups.

The impact of this strange and huge artificial building on the tribe is unprecedented. There are people coming and going on the construction site all day long, and it is extremely noisy and lively.

As the fire kiln top-up filling was officially announced to be completed, the entire tribe went completely crazy, dragging the old and the young out of their nests, and they all ran to the foot of the mountain to watch the fun.

Mother Ba was even more excited and couldn't describe it. She got a string of necklaces covered with shells and various animal bones from somewhere. Her head was covered with feathers and a wooden staff carved with strange patterns. She looked like an ancient evil old witch, singing and dancing in front of the fire kiln.

A group of savages also shouted at the fire kiln and the sky, like a group of demons dancing around, making Xu Chen almost mentally ill.

In order to show that he was very sociable, his scalp was numb and he danced with cramps.

After a long time of lively, a group of people finally got tired of jumping. Then a woman brought several different pigments with shells and carefully applied them on him.

Then, he became a paint man covered with colorful and strange patterns.

"Wuga!"

Mother Ba raised her staff and shouted at the sky.

"Wuga~"

"Wuga~"

"Wuga~"

All the savages were excited and shouted loudly, and they were so excited that they were very excited.

Amid the cheers, Xu Chen felt a illusion of boiling blood.

A few handfuls of this pigment from the dog are poisonous, and it is numb and itchy when applied to the body.

The fire kiln capping ceremony was completed. Under the lively onlookers, Xu Chen arranged for people to find a large amount of dry firewood and dry grass to start smoking the kiln, and personally lit the fire in the furnace.

When the rolling smoke soared into the sky at the foot of the mountain, a group of savages screamed even more excitedly.

Xu Chen was also very excited.

What he ignited was not only a fire kiln, but the first industrial fire of primitive human civilization.

The use of fire to make pottery indicates that humans have entered a new era of use of energy.

The fumigation kiln will last for several days, because only by thoroughly drying the soil and stones will be completely solidified and solidified, so that the kiln will not collapse.

In addition, in order to facilitate the production and dry clay, a row of pergolas was built next to the earthen kiln.

Next is to dig a hole to get the soil and make the clay.

Below the rolling low hills near the foot of the mountain, there is good quality clay.

In order to cooperate with Xu Chen to make the exquisite pottery as soon as possible, Mo Ba arranged for two adults, a man and a woman to help.
