The sunlight poured down, but after being blocked by the thatched hut, it became less scorching.

The wind blowing along the river makes this place much cooler than other places.

Under the straw hut, Heiwa, the first potter of the Qingque tribe, was holding a small jar in one hand and a brush made of animal fur, gum and wood in the other, and was gently brushing wood ash on a small piece of mud about four centimeters long and two centimeters wide.

His movements were gentle and his expression was focused. He was more careful and serious than when he had brushed other pottery before.

This rectangular piece of mud, which is less than one centimeter thick, is not flat. There are traces of carving on it.

The piece that Heiwa is painting now has four characters engraved on the front. The two on the top are "Qingque" and the bottom one is "Heiwa".

There are many such small clay tablets, more than one hundred in total, which exactly corresponds to the population of the tribe over the age of three.

After brushing the front sides of all the small clay tablets, the front one has dried.

Heiwa came over and used a thin piece of bone to shovel lightly, then carefully turned the clay slab over.

The back of the clay tablet depicts a bluebird spreading its wings as if ready to fly.

This bluebird is very lifelike.

He turned over five clay tablets in a row, and on the back of each one was a green bird spreading its wings, ready to fly.

Heiwa's gaze moved over these greenbirds, and his love and respect were clearly revealed in his eyes.

Not only are the images of these bluebirds lifelike, but more importantly, each one is exactly the same!

When the Son of God made this request, even the people in the tribe who were the best at doing these things did not dare to agree.

It is not difficult to draw a bluebird, but the difficult part is to make every bluebird look exactly the same!

One or two is still okay, but the Son of God’s request is more than a hundred.

More than a hundred identical bluebirds?

Anyone who knows a little about this aspect knows how difficult it is. It can even be said that this is an impossible task.

Not only did he think so, even the witch in the tribe and Shi Tou, who was most proficient in things like words, also believed that such a thing was simply impossible to accomplish and happen.

However, this mood did not last long. Three days later, when the Son of God sniffed and returned to the house carrying a piece of wood, their inherent cognition was broken.

What they thought was impossible to accomplish was solved by the Son of God in a not-too-difficult way.

The solution is the small piece of wood held by the Son of God.

Press the piece of wood slightly against the newly formed, wet clay slab, and a greenbird will immediately appear on the clay slab.

After seeing the solution, Heiwa's mind suddenly became clear, but he also kept slapping his head.

I shouldn't have failed to think of such a method.

When making pottery, people sometimes use fish bones, wooden sticks and other things to press out some marks on it. The principle is the same as this.

Why can't I think of printing a green bird on it?

After looking at the identical green bird on the back of the clay tablet for a while, Heiwa, still feeling a little annoyed, couldn't help but slap himself on the head twice, and then continued to brush wood ash water on it.

He did this work extremely carefully, because the Son of God had told him very seriously before, saying that after these clay tablets are fired, they will become their tribe's... ?

ID card?

Heiwa scratched his head, feeling a little unsure.

Well, that seems to be what it’s called.

According to the Son of God, this thing called an identity card corresponds to each of them, one for each person, to prove that they are members of the Green Bird tribe.

Heiwa found it difficult to understand why the Son of God had to have such an action and there was no explanation for it.

Aren’t I and other people in the tribe members of the tribe?

Why do we need to use a pottery fragment like this to prove it?

Heiwa brushed all the clay tablets, looked at them, thought about the intention of the Son of God in doing these things, and scratched his head in confusion again.

After a while of this, one can only attribute it to the fact that one's own level is too low and one cannot understand the idea that the Son of God is superior to others.

Two days later, this carefully crafted 'identity card' came out of the oven.

Han Cheng picked up an ID card and looked at it carefully for a while, then nodded with a hint of satisfaction.

Although this ID card is a bit simple, it has everything it should have and can serve as the tribe's first-generation ID card.

It will not be too late to upgrade once the technology matures.

Getting ID cards for people in the tribe now seems a bit of a joke.

After all, the population of the Qingque tribe is just this small now, and they all live in the same compound, eating, living and working together, so they are very familiar with each other.

Not to mention showing half of the face, even if only half of the butt is shown you can still recognize who it is.

Just as the people in the tribe thought, they could confirm that the other person was a member of their tribe without using an ID card, which seemed a bit redundant.

Han Cheng naturally understood these, but the ID card is not just used to prove identity. If something else is added to it, then the meaning of this thing will be different.

In addition to this batch of identity cards carefully made of pottery, Han Cheng also plans to make another batch of identity cards made of small wooden tags.

Of course, this second batch of identity cards were not for the people of the Qingque tribe who already had pottery identity cards, but were prepared for those who joined the Qingque tribe later.

Those who hold a ceramic ID card are first-level citizens of the Qingque tribe, and those who hold a wooden ID card are second-level citizens.

First-level citizens can enjoy many conveniences, just like the Qingque tribe is living now.

Second-level citizens are subject to some restrictions in the rights they enjoy. For example, their daily food and living place are somewhat different from those of the elders of the Qingque tribe.

This kind of differential treatment is not unfair.

Treating everyone equally without distinction is precisely the greatest injustice.

After all, the elders of the Qingque tribe have put in so much effort for the tribe, which has led to the current situation where the tribe has no worries about food and clothing.

Those latecomers, as soon as they come in, enjoy the same treatment as the old ones. No matter how you look at it, this makes people feel uncomfortable.

Before, the Green Bird Tribe had few people and was very weak. In order to promote the rapid development of the tribe, Han Chengdu did not take such measures when dealing with the Pig Tribe and the Bone Tribe.

Now that the Green Bird Tribe is no longer too weak here, we can start working on this matter.

Of course, people with a second-level identity do not always have a second-level identity. After living in the Qingque tribe for a certain period of time, their identity cards will be replaced from wooden plates to ceramic plates.

If there are people who perform outstandingly and make great contributions to the tribe, this time can be greatly shortened.

Han Cheng has not yet decided on the specific standards. It will not be too late to decide based on the circumstances when new people join the Qingque tribe.

By doing so, on the one hand, it can win the hearts of the elders of the tribe and prevent them from feeling resentful due to injustice. On the other hand, it can point out the path of promotion for those who come later, which will help them integrate into the Qingque tribe as soon as possible and make more contributions to their tribe.

With these additional things, the ID card, which seemed to be useless at the time, becomes of great significance.
