The four directions of east, west, north, and south are marked on the circular piece of paper.

Moreover, the degrees are evenly carved out between the directions, and nine spaces are carved out between each interval.

In other words, there are ten degrees between each space.

In fact, it can be depicted in a more detailed and precise manner.

However, the first compass I tried to make was still a bit small. If I continued to use a quill pen to carve it into finer parts, it would appear too bloated and messy, making it difficult to identify.

However, these are all minor issues. As long as you want to be meticulous, all you need to do is divide and plan carefully when making it later.

Now that this has been successfully produced, these are just minor problems.

There is a small hole in the middle of this round cardboard piece, which can just fit through the small round bronze pillar, and the size matches the round bronze bottom below.

A layer of fish bladder glue has been applied to the bottom of the circular piece of paper. After pressing it down, it just matches the bronze bottom below.

After finishing this, Han Cheng brought over the magnetized iron needle.

This needle is not an ordinary needle, but one specially customized by Han Cheng by the people in the tribe.

It is pointed at both ends and wide in the middle, and there is a hole in the middle, which can just fit it on the small bronze pillar in the middle that serves as a shaft.

After some debugging, I got something like a 'hat' and put it on top of the bronze pillar for fixation.

Of course, this kind of fixation is the kind of fixation that is not next to the pointer.

The purpose is not to fix the pointer, but to prevent the compass pointer from slipping off the bronze pillar if someone holds the compass upside down in the future.

This time, before assembly, Han Cheng made some adjustments and experiments in advance, trying his best to get everything done.

So after following this set of processes and assembling all these things, there was no embarrassing situation like when making a simple compass before.

After Han Cheng installed it, made some minor adjustments, and placed it flat, the half of the pointer that Han Cheng managed to dye red was already pointing firmly at the same point.

Han Cheng marked the north with a red pen.

Han Cheng shook it back and forth a few more times, then put it down, and then looked at the effect of the compass.

The purpose is to test the quality of the compass.

So far, the quality of this newly manufactured compass is still very good.

After being shaken by Han Cheng, there was no such thing as falling apart.

Han Cheng placed it flat on the table, and the pointer quickly pointed to the north and south sides.

Seeing this, Han Cheng couldn't help but smile with satisfaction again.

Actually speaking, this compass still has some shortcomings.

The shortcoming is the lack of a transparent lid.

It would be perfect if you put a transparent lid on it.

In this case, you can use this transparent cover to protect the parts in the compass and avoid damage from external forces as little as possible.

In Han Cheng's impression, there are only a few types that can take on this important task - glass, plastic and some extremely high-quality crystals!

But these things are not available in the tribe now, so there is no use for them.

What Han Cheng could do was to use some good quality and suitable leather to make an opaque cover and cover the compass firmly.

Open it when in use and close it when not in use.

Although it is not as convenient and beautiful to use as those transparent lids, it can still provide some protection after all, which is better than no lid at all.

Holding this thing with a soft leather lid, it looked a little awkward, and Han Cheng couldn't help but feel a little moved in his heart.

Perhaps, in addition to using this kind of leather cover, my tribe can actually get some transparent things to use as the cover of this compass!

Of course it is not a pure and flawless crystal with excellent transparency.

To be honest, there is no such thing in the tribe now. Very good quality jade and raw jade are not uncommon. There are piles of them in one house.

Plastic is not the same thing. Although it was very common in later generations and once became an important part of pollution, at this time, Han Cheng couldn't even feel this kind of happy trouble...

What makes Han Chengzhi excited is glass!

Because just now, his heart suddenly moved and he remembered an online novel he had read.

Some of the protagonists above rubbed out the glass, and then received a lot of admiration from a large number of people, and at the same time, they also experienced rapid improvement in wealth and status.

In later generations, Han Cheng was a person who preferred to read novels. At first, he read fairy tales, but then slowly changed to historical novels, and later he basically read historical novels.

Many historical novels have one characteristic.

That is, many people who have traveled back in time can remember how to make many things, such as glass making, horseshoes, efficient modern steelmaking, etc.

These things will promote the development of the plot, and can also lead to a lot of pretense, slaps in the face, and big gains such as getting rich!

As a person who has been immersed in this type of novel for some time, it is reasonable for Han Cheng to think of some things about glass manufacturing at this time.

After all, these books contain all kinds of weird and strange knowledge.

Even Han Cheng himself believed that if he could memorize all the strange knowledge written in the history books he had read, then he would be able to lead the Qingque Tribe and quickly achieve another goal.

One takes off!

It can even quickly enter the industrial age!

After all, there are too many weird things in there!

As small as needles and thread, mosquito coils, toilet water, bras, auntie towels...as large as red cannons, flintlock guns, battleships...etc., it is all-encompassing and diverse, everything you need!

Of course, in addition to these, there are also many poems, lyrics and songs specially used to show off and enhance one's reputation.

But Han Cheng doesn't envy these things.

This is not only because he has kept a lot of these things in his mind, but also because this thing is really not available in this era.

Think about it, you recited the song "When will the bright moon come, ask the sky for wine" to a group of primitive people.

In such a case, you will receive nothing but a circle of primitive question mark faces.

As for things like "The moon is on the willow branches, people make appointments after dusk," "Guan Guan Jiujiu, in the river island. My fair lady, a gentleman is a good man." etc., at this time, the effect is really far less than "I want to follow you"

If you are sleepy and have a baby, the effect will be good...

According to a historical novel that Han Cheng once read, glass is made of sand.

As for glass bottles, they are blown out of a pipe or something.

As for the rest of the details, Han Cheng himself didn't know.

He himself couldn't remember clearly, whether he had forgotten it or it wasn't written in the novel.

But these alone are enough.

After waiting for a while, I told Hei Wa, a guy who wanted to throw everything into the fire, these things, and asked him to study and explore.

Today, Heiwa is already familiar with making pottery, porcelain and molds.

As an exploratory talent, these things are no longer challenging for him.

So Han Cheng could predict that when he told Hei Wa about this new direction of exploration, this guy would be very excited!

I will definitely be very happy to agree to this!

After all, this is something that has a certain connection with kilns, and after it is completed, it will also test one's skills.

There were many people watching around. After all, these days, as Han Cheng handed over various tasks of making compasses, and also personally cooked for the trade team headed by Han Yousan, as a reward,

People in the tribe had already spread the news among the tribe that the people from the trade team had brought back very useful magnets, and that the Son of God was planning to use these things to make a very magical compass.

Even though such a long time has passed, the people in the tribe still haven't changed their habit of watching the strange things with the Son of God.

Even in the eyes of many elders in the tribe, following the Son of God to watch something strange is much more interesting than the model plays performed in the tribe.

After all, after such a long time, many of them have watched the model drama many times.

Visual fatigue has occurred.

But following the Son of God to see strange things is completely different.

Because the Son of God is always able to come up with many strange things, people can't help but be amazed by them.

For example, at this time, everyone present felt extremely curious and novel when they saw that no matter how they moved the compass, when it finally stopped, the needle would point straight to the north and south.

I felt that this time I and others did not spend time here watching, it was really worth it.

Looking at the reactions of everyone present, Han Cheng suddenly felt like doing a live broadcast.

If I were to live broadcast in this era, judging from the behavior of everyone now, it is conceivable to make a lot of money.

Of course, it is very likely to be like this - you receive a piece of dried meat as a reward from a pine branch, and you receive a piece of dried vegetables as a reward from a stone...

Not all of the people standing here watching the fun are here to watch the fun, there are also people who are here with thoughts and a strong desire for knowledge.

Just like a stone that has been prepared for witchcraft for many years.

Talking about this matter, Han Cheng would sometimes think in a funny way that one day Shitou would say with a sad face, "How can there be a witch who has been preparing for forty years in this world?"

Shitou is a part-time teacher in the tribe, and his thirst for knowledge is as strong as ever.
