Xia tribe.

Wang Wei, Xia Bing, and Xia Shuang ground the fine sand in a pottery, and then filtered it several times with a fine sieve woven with a braided group until enough fine sand accumulated. Then they dried the fine sand in a fire and there was no trace of it.

Moisture.

Wang Wei's request is to keep the fine sand in this dry state from now on.

Xia Tu also brought the hourglass and measuring cups that Wang Wei needed, and she made more than ten hourglasses of different sizes.

Wang Wei chose the hourglass that felt best and had the smoothest interior.

It turns out that in order to make the inside of the hourglass smoother, Xia Tu and her pottery team polished the hourglass by hand.

After everything is ready.

Wang Wei used the sun to mark the position of the small wooden stick, and the fixed hourglass began to pour sand. A clay pot was placed under the hourglass.

He arranged for Xia Bing and Xia Shuang to persist until this time tomorrow, and asked them to continue adding fine sand to the hourglass. When tomorrow's sun shines on the mark of the small wooden stick's previous day's position, the day will be considered complete.

Wang Wei has created a tool to record time, but there is no way to record dates, which is also a difficult thing to do.

He looked at the sun in the sky, in a daze.

Because he is very entangled in the primitive society he lives in now. Is this planet the earth? If not, does it make sense to do this?

He watched Xia Bing and Xia Shuang follow his request seriously;

He watched Xia Tu's skin getting darker and darker. Because she had been in a high temperature place for a long time and was exposed to infrared radiation, her skin began to turn black and rough;

He looked at the people who were busy building the city wall in the distance.

He immediately felt that doing this was very meaningful and worth every effort he made to implement it.

Wang Wei then gave Xia Shuang, who could draw birds, a new task, which was to record the weather conditions every day. Every day it was windy or rainy, and the sunrise and sunset were recorded according to the time of day.

Since Wang Wei has not yet taught them Chinese characters, recording weather conditions is still done by drawing pictures.

For example, if it is a sunny day today and the sun is shining, simply draw a circle and draw a few slashes around the circle.

If it is cloudy today, simply draw two overlapping clouds.

If it is cloudy today and the sun comes out at noon, first draw a simple circle and then a simple overlapping cloud.

If there is light rain today, simply draw a cloud and draw a small dot under the cloud.

If it rains heavily today, simply draw a cloud and draw three small dots under the cloud.

If there are thunder and lightning, snow, fog and other weather conditions, Wang Wei lists them all one by one and gives different graphic representations. This kind of drawing method is easy to record and has high recognition.

And let Xia Shuang record the time of dawn and dark every day. When did the grass and trees outside start to sprout and grow? When did they bloom? When did they bear fruit? When did they turn yellow? What

Time to wither? Wait.

Considering where to record it, it was very difficult, and finally asked Xia Tu to bake several large pottery boards specifically for recording.

The Xia tribe doesn't have paper yet. In fact, there are many ready-made materials, such as bamboo, bark, rattan, etc., but Wang Wei really doesn't have time or more people to do it now. Now everything is focused on building city walls.

These recorded things were very valuable, and a house was built to store them. After the new city was established, he planned to build a bell tower and a room in the bell tower to maintain the correct operation of time, store logs that record dates, etc.

After completing their tasks, Wang Wei still had one more thing to do.

In the knitting group, Wang Wei encountered trouble when he arranged for Xia Yu to make long-sleeved trousers.

The main reason for making long-sleeved trousers is that it is difficult to sew the sleeves and trouser legs. The sewing is too rough, causing air leakage and not keeping warm.

However, Wang Wei invited Aunty Rong, Aunty Concubine, Aunty Fox and Old Man Yu to study together.

In fact, Wang Wei also knows their difficulties, such as the fur is too hard, and in order to soften the fur, the excess fat on the fur needs to be removed, etc.

The best materials suitable for making leather jackets and pants are sheepskin and rabbit skin. Sheepskin is soft and rabbit skin is warm.

Wang Wei gave them a suggestion and asked Xia Yu to do it.

His advice is:

First, soak the fur in clean water for at least half a day. If that doesn't work, boil it in warm water to make it soft;

Then use a knife to scrape off the remaining meat and dirt attached to the leather board;

Then put it in warm lime water and wash it with a brush to completely remove the grease and dirt.

Finally, put it in warm water, add salt and lime to the water and soak it completely.

Remove the soaked animal skin from the soaking liquid, clean it, stretch it with a frame, and place it in a ventilated place to dry in the shade.

The process is a bit complicated, but this is the best tutorial he has ever seen on making leather jackets using local techniques.

While Wang Wei was communicating with the knitting group, Xia Jin ran to him.

He said that many savages had gathered on the other side of the river. I wonder what they were doing?

Wang Wei asked Xia Yu, Rongma and others from the hunting group to continue, and he hurried towards the Yong'an River.

On the bank of the river, Hu Meizi stood on the simple dock, and the other members of the logistics team spread out and were closely monitoring the other side.

Wang Wei looked at Hu Meizi and thought about the massage she gave him yesterday. He still hasn't figured out whether Hu Meizi did it unintentionally.

When she saw Wang Wei arriving, she said naturally:

"Your Majesty, do you feel something is wrong with the savages?"

"What's wrong?"

"Although there are not many savages on the other side today, they are not like yesterday. They are not holding weapons. They are shouting on the other side. What do they seem to be saying?"

Wang Wei didn't see anything going on. Could it be that they wanted to communicate with the Xia tribe? Or maybe they wanted to have peace talks with the Xia tribe?

"I don't know what their ghost names are. No one in our Xia tribe understands their language. Does that Sang girl understand it?"

"I asked her, but she didn't understand."

"Xia Jin goes and invites Sang Nu over. I'll ask her."

Xia Jin ran in a hurry.

"Have everyone in the hunting team set up traps?"

Hu Meizi said: "Yes, they haven't come back yet. Do you want to call them back?"

Wang Wei shook his head, they would be busy setting up traps these days.

"No, let them continue to install traps. There are about fifty or sixty people on the other side. They don't seem to be attacking the Xia tribe. However, these savages are so annoying and have greatly affected the development of the Xia tribe. It would be great if they could be eliminated!"

It's a pity that now the Xia tribe can only rely on this river for protection."

"Your Majesty, do you really plan to destroy them all?"

"Hey, I'm just thinking about it. I'm not strong enough and I lack weapons."

"The iron-smelting team has made a new iron spear, can it be divided into a logistics team?"

"The iron-smelting team has only made a dozen new iron spears, and I will divide them into your team's half. Alas, this is all I have left."

Hu Meizi beamed with joy.

"Also, I asked Xia Dao to make a new weapon. It's a bit smelly, but it should be very effective."

"What is it? Can I see it?"

"Not yet, let's wait for that thing to ferment for a few more days."

After a while, Xia Jin called Sang Nu over.

When Sang Nu came to the Xia tribe for a day, the wealth, living environment, and population of the Xia tribe greatly exceeded her imagination.

When she escaped, she still had wounds on her body. When Mei treated her, she briefly introduced the situation of the Xia tribe to her. While she was shocked, she was also full of longing and desire for the life of the Xia tribe.

She knew that the little man in front of her was the king of the Xia tribe and the leader of the tribe, so she looked at Wang Wei a little nervously.

"Don't be nervous. Can you tell what the savage on the other side means?"

Sang Nu looked up and didn't seem to see anything, but after a while, she discovered something.

Hu Meizi asked: "Did you find anything?"

"There are people from the Snail tribe among them."

"How many people are there?"

Sang Nu looked carefully and said, "There is only one person."

"Which one?"

Sang Nu pointed her finger.

Wang Wei couldn't tell which one she was referring to?

"Did you know him before?"

Sang Nu nodded.

Wang Wei looked at the group of people, all dressed the same and with disheveled hair. He couldn't tell them apart for a moment and thought they were all savages.

The man from the Snail tribe is wearing the same clothes as the savages. Could it be that he is a traitor?
