This is the Fire Tribe, who migrated from the other side of the mountain about 200 times before the nuts ripened, and the former tribal territory was flooded.

They had to migrate, and at the beginning of their migration, the tribe was attacked by wild beasts, and the number of people kept dwindling, until one dark night, the sky thundered and lightning, and fire appeared.

The fire burned the trees, drove away the wild beasts that peeped around, and ensured the safety of the tribe, and the tribe sacrifices at that time invited the fire into the tribe.

Since then, the tribe has migrated much safer, repelled many wild beasts, and finally found this ideal, safe, new tribal territory.

Since then, the tribe has regarded fire as the protector of the tribe, and sacrifices to it every year to thank him for his protection of the tribe, and it is at that time that the tribe officially takes the name of the fire tribe.

The tribe eats roasted food, and it is only during the sacrifice that they find that the food that has been burned by fire is more delicious, otherwise, the tribesmen are still eating raw meat.

Oh, and the rest of the history is mainly about the general situation of the tribe, such as the basic information of the tribe's leaders, what kind of great prey the tribe hunted, and most importantly, the population of the tribe.

How many children are born and how many clansmen die every year are all remembered very clearly, and they also record in detail the two hundred years of the Fire Tribe, from 72 people at the time of its establishment, to 586 people now.

After the festival told the whole history of the mural, he left with the children and returned to the tribe's station. Su Ming knew the history of the tribe, but he didn't gain more information about this world, maybe it was a primitive society under the productive forces, and the area of activity of the tribe was so important.

On the way back to the tribe, Su Ming kept thinking about the situation of the tribe's black flame, I don't know why, its figure has always been in his mind, as if it was deeply engraved on the skull.

..................

Time flies, a month has passed, and most of the leaves under the mountain have turned yellow, and when the breeze comes, the leaves leave the branches of its remembrance and flutter into the embrace of the earth.

Autumn is coming to an end, winter is coming!

After a month, Su Ming's original injuries had already fully recovered, and he was now collecting firewood for the tribe to survive the winter.

Su Ming and his friends carried a dead tree back to the cave, placed it, and waited for others to process it into small sections of firewood.

In order to ensure the safety of the children, the adults transported the trees to the bottom of the tribal caves, and then the sturdy women carried the large trees, and the small ones were transported by the small children.

Except for the adults who collected and carried firewood, all the others went out to hunt, hoping to hunt more prey at the last opportunity, so that the winter would be more generous.

It has been eight days since the beginning of collecting firewood, and looking at the piles of timber, and then looking at the forest below the mountain without seeing a little sparse, you can know how abundant the great natural resources are.

On the ninth day, the situation changed, and Su Ming and the others were arranged to transfer the processed wood to the inside of the cave.

Looking at the surrounding companions who stayed together, with such an expression on their faces, Su Ming knew that the memory he got was very incomplete, but he didn't dare to ask his companions, so he had to carry the wood and follow behind everyone, and move towards the unknown destination together.

The road was flat, and it was the road to the sacrifice in the first place, but the procession passed by the stone chamber of the sacrifice and did not stop there.

After passing through the sacrificial stone room, about another 300 meters or so, Su Ming and the others entered a stone room again, and the surrounding area was full of traces of people's lives, the fire pond built with small stones, the huge stone room where wood was stacked, and the entrance of the cave blocked with trees and stones, all showed that the tribe would spend the winter here.

Su Ming is very similar to opening the blocked cave to see what is going on outside, but he also knows that this is impossible, it is not yet time to open the cave, there are only a few adults who lead the team here, and the others are children.

The transportation lasted all day, but only a small part of the timber was transported, and the piles there were not only less, but more than that, and the transportation efficiency was too low.

Lying on the bed, feeling the pain in his shoulders and back, Su Ming tightened the rough animal skin on his body, this is the tribe's new winter leather coat, usually only a pair of animal skin pants, and he began to cherish those trucks, and even the little wheelbarrow, it is much better than carrying it on his shoulders now.

Su Ming thought about it, how to build the wheels, eh, I don't know, forget it, let's sleep, there is still so much wood to carry tomorrow.

Well, no, no, the tribe already has ropes that can make some improvised tools for carrying wood, such as pestles.

As soon as he said it, Su Ming immediately got up, that is, got up from the ground, and went to the place where the wood was stacked to find suitable materials for making pestles.

In the huge pile of wood, Su Ming quickly found a suitable wooden stick, six trunks about five centimeters, although they are all of different lengths, but they can also make a practical pestle, but it is a little ugly.

Seeing Su Ming making a pestle by the fire, the warriors on night duty in the tribe didn't care, generally speaking, as long as you didn't do anything harmful to other people in the tribe, no one else would interfere with you too much, of course, provided that you were in the time of rest.

The first time I made a pestle by hand, it was not very smooth, after all, Su Ming had seen it and only knew its basic structure, and he didn't do it himself.

However, Su Ming dismantled and dismantled again, and after a few times, an ugly faceless pestle appeared in this world.

The next day, Su Ming continued to transport timber, but today was different, he carried a pestle on his back.

One trip, two trips......

The teammates on the same team became more and more tired and slow, but Su Ming suddenly emerged and performed well. attracted everyone's attention, but in fact, they couldn't pay attention to him.

While everyone paused to knead their shoulders, Su Ming continued to transport the wood as if he was fine, as if his shoulders would not hurt, and each time he transported more wood than others.

You know, yesterday, he was the same as everyone else, but today he wants to be a different person. Could it be the weird shelf he's carrying?

"Su Ming, what's wrong with you today, aren't you tired at all?" Someone finally couldn't help but ask.

"Hehe, you see, I have a pestle, when I carry wood, it's much easier, don't believe it, you try, see if it's like this. Su Ming said what he wanted to say for a long time, and invited him to give it a try.

In fact, when Su Ming first made the pestle, he wanted to promote it, but there was no actual test, and the other clansmen in the tribe would not believe it, and transporting timber was just enough for everyone to see the actual effect, so that this simple and practical tool could be popularized quickly.

"Really, hit ...... with this Something, it's really easier, it's half more wood than me, and it doesn't feel too tiring to carry. This is really amazing, Su Ming, help me make one at night, okay?" said his companion, who was carrying Su Ming on his back.

"Okay, no problem, but it's time to make one for you. Su Ming generously promised.

As soon as they heard that Su Ming was willing to help, the other partners also begged Su Ming to do the same, after all, it had been experimented, and this pestle was indeed effective to save a lot of effort and reduce pressure on the shoulder.

After a day, Su Ming and the others each carried an ugly pestle on their backs and began to transport timber, and the efficiency of transportation was greatly improved, at least the timber mountain at the cave did not grow taller.

This caused a burst of surprise among the people who collected wood, and they thought that their collection speed had slowed down, and after knowing the situation, they increased the speed of collecting wood.

And Su Ming didn't have the heart to pay attention to these things anymore, and now he was attracted to another thing......
