Xu Chen threw the bark to Gu Heju, and then a group of people rushed to blow it. The whimpering sound continued one after another, and the huge sound echoed in the valley. Xu Chen stood beside him and his face was thrusting.

I don’t feel that I’m bragging myself, but I really hear others bragging loudly and it’s very unpleasant.

"Wow, bad!"

The bark horn was originally made casually and was not strong. It broke after a few blows. A group of people watched as they raised their hands and turned into a horn with a long bark, and then they all raised it with their fingers, indicating that it was him who blew it.

He was also shocked, and was at a loss when he was carrying a long serpentine bark.

"It's not broken, roll it up and that's it!"

Xu Chen took the bark and quickly rolled it into a trumpet shape. He tied it randomly with thin bark, inserted the willow flute into it and turned into a bark trumpet again.

"Soga~~"

Now everyone understood the principle of making this bark horn, and they all showed excitement and surprise.

Gu pulled out his bones and daggers from his waist and ran towards the willow forest on the river beach.

"Horse karao!"

A group of children cheered and rushed away.

Xu Chen breathed a sigh of relief and prepared to return to the yard.

The bark trumpet is simple to make and can be easily made at first glance, so he doesn't need to teach it himself.

Not to mention scaring this thing, it can scare people even if they come suddenly.

I guess the group of horses were very scared today, and they should not cause trouble to the crops again soon.

Besides, Gu Heju took a group of children and waited for a while and it was even more noisy and scary when blowing, and the birds shouldn't dare to get closer.

As long as you ensure that the seed maturity period of this half month has entered the harvesting stage, there will be basically no problem.

"By the way, where is the monkey?"

Xu Chen had just walked a few steps and suddenly remembered that he had not seen any monkeys that he usually had on his hands today.

“Wow!”

I came to my senses and looked at the direction of the farmland, but the sky was vast and the wind blew the grass and my heart was cold. Not to mention monkeys, there was not a single bird.

Xu Chen immediately understood that the group of people threw the monkey away when they ran back just now.

"I'll go find..."

He raised his legs with shame on his face and was about to leave. Xu Chen quickly grabbed him and said, "No hurry, I guess I was frightened by the sound of the horn. You can try summoning me!"

He shouted loudly, and as the sound echoed in the valley far away with the wind, soon, he saw two monkeys pulling ropes out carefully in the grass in the distance, looking around with great vigilance and horror, then squeaked and rushed into the yard and hid.

Although only two came back, Xu Chen still breathed a sigh of relief.

This group of monkeys has been raised for half a year and has become accustomed to living with humans. Every day, they eat and drink enough and go out to patrol and help catch mice, snakes and birds. In addition to being more noisy, they actually have made great contributions. Now the entire tribe has regarded them as half members of the tribe, and throw some food they bring back every time.

In fact, living with humans not only has food, drink, and shelter from wind and rain. With the IQ of a group of monkeys, you can also understand the difference between saturation and fullness.

Since moving to the foot of the mountain, even if I let the feeding go, I have never run away.

At present, the monkeys must have been scared by the sound of the bark horn, and they might have run back later.

So he went back to the yard without any care.

The result was similar to what he thought. He kept shouting loudly on the river beach. Soon two monkeys ran back. However, as soon as they arrived at the gate of the yard, Gu and a group of children came back to show off with a prepared bark trumpet, and immediately frightened the two monkeys and jumped to the wilderness.

Moreover, the terrifying and loud bark horn not only scared the monkey, but also scared the four children in the family to cry.

Mother Ba and a group of women rushed out and grabbed Gu and a few wild children and scolded him. So Gu had to take a group of children to flee to the river beach and continue to blow the trumpet.

Xu Chen sat in his room, listening to the sound of horns coming from outside the yard, his face kept twitching.

Since the invention of playing the willow flute, a group of children have only a few hands, and they keep blowing inside and outside the yard all day. After being scolded by Mo Ba and a group of women, they finally stopped for a few days. Now with this louder and more terrifying trumpet, they may not be quieter.

However, although the bark number is simple to make, it is easy to break even if it is rude and not said. If you want to solve the problem once and for all, you should still make the horn number.

After all, it is still necessary to train the army as an order in the future.

It would be great if I could make the cowhide drum.

I put a few sides near the farmland and beat them a few times a day. I guess the entire valley of birds and beasts can't stay there.

It’s a pity that there is cowhide, but the drum can’t be made, and there are no sharp and strong tools to deal with the wood.

"Take it slow!"

Xu Chen sighed, and selected a good-looking one from the pile of cow horns in front of him, and found a bone knife to cut it slowly.

Just remove the horns and make the rest easier.

However, it is extremely difficult to saw this thing open just by relying on simple tools such as bones and stones.

You can only use the most primitive, savage and oldest tricks.

Water dripping through the stone, and the rope sawed and broken.

As long as you work hard, you can grind an iron pestle into a needle.

Before traveling through time, the ancestors of China had left him with enough life skills and philosophy, and he believed that this difficulty could be overcome.

What's more, he lacks everything at the moment, but he doesn't lack time.

So in the extreme heat and silence, Xu Chen sat in front of the brick table, patiently using the bone knife to slowly compete with the ox horn, with a hideous look on his face, half an hour passed, and a small gap slowly appeared on the ox horn.

...

The appearance of the Bark Number was like a magical artifact against the sky, and it suddenly became the favorite toy of all men and children in the tribe.

Every day from morning to night, various whistle sounds of different heights and lengths can be heard outside the yard.

A peaceful and peaceful life is completely broken.

Xu Chen was suffering.

He finally realized the joyful and lively Africans.

It seems that there are bloodlines and genes that make all kinds of noises in their bones.

In the past, I used to scream a few times when I was in trouble. Now I keep calling you, and I will blow wherever I go.

However, since the Bark Slot, under the stimulation of this terrifying noise, all the beasts and birds that covet farmland and crops have been really not scared away.

I rarely hear Gu Heju complain about wild animals stealing crops.

As the days passed, not only did he become accustomed to this noise, but after a group of monkeys were frightened for a while, they also slowly began to get used to the call of the horn. Every time they saw Gu Heju and a group of children going out with the horns, they immediately jumped and jumped up.

The crops in the farmland are also yellowing and ripe with the sound of the horns.

The Ba people finally ushered in the first harvest of the farming era after Xu Chen traveled through time for a year.

In order to compete with birds and the weather, all the women in the tribe mobilized, including pregnant women. In addition to the few hunters who were going to hunt, the men who made other tools and defended the family also helped. Even three babies who were still breastfeeding were taken by the field and were taken care of by several children. During the collection and rest, they quickly sipped breasts and continued to be busy.

The woman carries a basket and picks and harvests in the fields with a basket. After collecting it, she will pour it into a large basket. The men carry it home with a shoulder pole and pour it on the open space in the middle of the yard to dry.

Xu Chen and Gu, three of them were responsible for drying at home, a group of monkeys and little wolves were responsible for driving away the birds that were stealing food, and Ye took two older children to be responsible for logistics, and returned and delivered water to those who worked.

The entire tribe entered the busiest and busiest time period this summer and autumn.

Although I am busy and tired, the results are also very gratifying.

The harvested dried grains were successively put into the warehouse, and several grain cellars were also filled one after another.

In order to protect these grains from insects, Xu Chen also brought Gu Heju back many peach leaves, hot pot and mugwort, and then dried them and mixed them with the grain.

This is an ancient habit of storing food in rural areas.

When Xu Chen saw that his father did this when he was a child.

As for the reason, it is probably that the leaves of these plants will emit a strong smell.

The farmland harvest took ten days to end.

Moreover, in order to roughly accurately judge the harvest of farming, Xu Chen also took the time to make a scale.

The weight is made of gold, and it is cut and polished into a thick and thin scale rod with a rough and thin end. Tie the rope and lanyard, hang the weight and set the astral plate, put a bowl of oats in a cloth pocket as a unit of measurement, weigh the scale of one pound, and then use five bowls and ten bowls to set the scale of five pounds and ten pounds respectively. After roughly determining the distance of the scale, divide and mark it according to equal distances. Such a simple rod scale is ready.

This scale can weigh up to fifty kilograms at most at a time.

Of course, precision is impossible.

Just be able to roughly confirm the harvest quantity.

Moreover, weighing with a rod scale is definitely much more accurate than estimating based on your eyes and feel.

Therefore, every time Xu Chen asked Gu Heju to carry the scale to weigh the grain next to each other before the dried grain was put into the warehouse, and then recorded it on the outer wall of each grain cellar with charcoal.

Although the tribe members were puzzled by Xu Chen's approach, they all felt unaware of Xu Chen's seriousness, as if Xu Chen was conducting a very serious ceremony. Therefore, they naturally became more awe of this thing called a scale.

Using gold as a weight, Xu Chen was both helpless and extremely proud.

In the world, there is no other one like him or a mighty poor man.
