I am a Primitive Man

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

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

That is to say, ten degrees between each space.

In fact, it can be described in more detail and more precise.

It's just that the first compass that I tried to make is still a bit small. If I use a quill pen to continue to draw the details, it will be too bloated and messy, but it is not easy to identify.

But these are all small problems. As long as you want to be meticulous, you can divide and plan carefully when you make it later.

Now that the production is successful, then these are minor problems.

There is a small hole in the middle of this round hard paper, which just fits through the small round bronze pillar, and the size matches the round bronze bottom below.

The underside of the circular piece of paper is already coated with a layer of fish swim bladder glue. After pressing it down, it just opposes the bronze bottom underneath.

After fixing this, Han Cheng took the magnetized iron needle again.

This needle is not an ordinary needle, but Han Cheng asked people in the tribe to customize it.

The two ends are pointed, the middle is wide, and there is a hole in the middle, just to fit it on the small bronze pillar in the middle that is used as an axis.

After some debugging, another thing similar to a ‘hat’ was obtained and put on the bronze pillar to fix it.

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

The purpose is not to fix the pointer, but to prevent the pointer of the compass from sliding down from the bronze pillar after the compass is turned upside down in the future.

This time, before assembling, Han Cheng made some adjustments and experiments in advance, and tried his best to do everything well.

So after this set of procedures, after all these things were assembled, there was no awkward situation when making a simple compass before.

After Han Cheng installed it, made some small adjustments, and placed it flat, the half of the pointer that was dyed red by Han Cheng was already pointing steadily. Han Cheng marked the north with a red pen.

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

The purpose is to test the quality of the compass.

For now, the quality of this newly manufactured compass is still very good.

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

Han Cheng laid it flat on the table, and the pointers quickly pointed to the north and south sides respectively.

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

In fact, speaking of it, this compass still has some shortcomings.

This shortcoming is the lack of a transparent lid.

If it is sealed with a transparent lid, it becomes perfect.

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

In Han Cheng's impression, there are no more than these kinds of things that can take on this important task-glass, plastic and some extremely high-quality crystals!

But these things are currently not available in the tribe, and it is useless to think about them.

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

Open it when in use, and cover it when not in use.

Although there is no transparent cover that is convenient and beautiful to use, it can still play a protective role after all, which is better than no cover.

Holding this soft cover with leather, Han Cheng couldn't help but feel a little moved in his heart, no matter how awkward it looked.

Perhaps, besides using this kind of leather cover, my tribe can really make something transparent as the cover of this compass!

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

To be honest, there is no such thing in the tribe. Good quality jade and rough jade are not uncommon. There are piles piled up in a house.

Plastic is also not a thing. Although it is extremely common in later generations and once became an important part of pollution, at this time, Han Cheng wanted to experience such a happy trouble...

Han Cheng's heart is the glass!

Because just now, he suddenly moved in his heart, thinking of an online novel he had read.

Some of the protagonists above rubbed the glass out, and then took advantage of the trend to reap a lot of people's awe, and at the same time, there was a rapid increase in wealth and status.

In later generations, Han Cheng was a person who liked to read novels. At the beginning, he was a fairy, but then slowly changed into history, and later he basically looked at history.

Many historical novels have a characteristic.

That is the people who traveled back, many of whom can remember the production methods of many things, such as glass production, horseshoes, efficient modern steelmaking, and so on.

These things will become the promotion of the development of the plot, and it can also bring a big wave of pretending to be slapped, making a fortune and getting rich!

As a person who has been immersed in this kind of novels for some time, Han Cheng remembered something about glass making at this time, which is also the past.

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

Even Han Cheng himself believes that if he can remember all the strange knowledge written in the history books he has read, he will be able to lead the Qingque tribe and quickly realize one after another. Take off one by one!

It can even move quickly into the industrial age!

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

As small as needle thread brains, mosquito coils, toilet water, bras, aunt’s towels... as large as red cannons, flintlocks, battleships, etc., it is all-encompassing.

Of course, in addition to these, there are many poems and songs specially used to pretend to be slapped and promote fame.

But Han Cheng didn't envy these things.

This is not only because he has a lot of these things in his mind, but also because this thing is really unusable in this era as early as now.

Think about it, you recite a song to a group of primitive people, "When will the moon be there, ask the wine to the sky".

In this case, except for the circle of primitive question mark faces, nothing else will be received.

As for the "willow heads on the moon, people meet after dusk", Guanguan Jujiu, in the river island. A fair lady, a gentleman is good. "Like, the effect at this time is really not as good as a sentence like "I want to sleep with you, give birth to a baby"...

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

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

As for the rest of the details, Han Cheng himself did not know.

He didn't remember clearly, whether he had forgotten it, or it was not written in the novel.

But just these are enough.

After a while, I told Heiwa these things to the guy who wanted to throw everything into the fire and let him study and explore.

Today's Heiwa is already familiar with pottery, porcelain, and mold making.

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

So Han Cheng can expect that this guy will be very excited when he tells Heiwa about this new direction of exploration!

I will be very happy to accept this matter!

After all, this is something that has a certain relationship with the kiln, and after it is completed, it is also a test of human skills.

There are many onlookers around. After all, these days, as Han Sung explained the various tasks of making compasses, he also personally cooked for the trade team headed by Han Yousan as a reward. The people in the tribe brought back very useful magnets for the trade team members, and the gods are also planning to use these things to make things that are very magical compasses. It has already spread among the tribes.

Even if it has been so long, the people in the tribe still haven't changed their habit of following the son of God.

Even in the eyes of the elderly in many tribes, it is more interesting to watch with the son of God than the model plays performed in the tribe.

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

Visual fatigue has appeared.

It is completely different from watching the strange son of God.

Because the son of God is always able to make a lot of strange things, people can't help but shine.

For example, at this time, all the people present, no matter how they are moved, when they finally stop, they will point their needles straight to the north and south compasses, and they feel extremely curious and novel.

I feel that this time I and others have not been watching here in vain, which is really worth it.

Seeing the reaction of everyone present, Han Cheng suddenly felt like doing a live broadcast.

If you are broadcasting live in this era, judging from the way everyone is now showing, it is conceivable to make a lot of money.

Of course, it is very likely to be like this-you received a tuft of dried meat rewarded by pine branches, and you received two dried vegetables rewarded by stones...

The people who stand here watching the excitement, not all of them, are watching the excitement here, and some people are here with thinking and a strong thirst for knowledge.

For example, the preparation of witch stones has been done for many years.

Speaking of this matter, Han Cheng sometimes really thought of it amused. One day the stone would cry and say, ‘Is there a prepared witch for 40 years in this world?’

Stone this guy, a part-time teacher in the tribe, still has a strong thirst for knowledge as always.

After standing here for a while, he finally spoke to Han Cheng for advice.

"God, why can the needle of this compass always point to the north and south? Why doesn't it point to other places?"

When the stone opens, it will pick up the thick fish, and it will be able to ask the idea once asked.

After thinking about it, Han Cheng smiled and said to the stone: "This is because the entire earth is a large magnetic field.

The north and south poles are equivalent to the two poles of this large magnetic field.

I don’t know if you have discovered a more interesting phenomenon these days.

After you break the same magnet, and then want to correct it from the broken place, it is impossible to do it without relying on external forces such as strong squeezing with your hands.

Moreover, even if they are forcibly paired with the hands, as long as the hands are released, they will separate, then change some directions, and then **** together.

The reason for this is that magnets have the characteristics of attracting opposite **** and repelling same sex.

The broken magnet has changed from the original one to two individuals, and naturally there will be the same **** and the opposite sex.

In other words, on this magnet, there are also north and south poles.

If two south poles face each other, they will repel each other, and one south pole opposes the other north pole, and they will attract each other.

As for the pointer of the compass, although it is iron, it has become magnetized and possesses the characteristics of a magnet after this operation.

That is, on its body, there are also the South Pole and North Pole.

Under the effect of the repulsion of the same **** and the attraction of the opposite sex, the pointer will naturally turn into a north-south direction.

Moreover, the part that is dyed red and has the characteristics of the South Pole points to the North Pole, while the part that is not dyed points to the south..."

Qingque tribe **** child small class started again.

Han Cheng, the **** son of the Qingque tribe, based on his knowledge about magnets and compasses, plus his own understanding, and the understanding ability of the tribesmen present, to explain this to the stone as easily as possible. I~www.wuxiaspot.com~ When Han Cheng started speaking, all the people present stopped speaking and listened very seriously.

However, the same words, the effect in different people's ears is completely different.

Take Shishi, for example, after Han Cheng finished talking about these things, it didn't take long for him to understand these things in a rush.

But even though more people were there, they knew what every word Han Cheng said meant, but after connecting them together, they wouldn't be able to understand it, they would not understand anything.

Anything like the Antarctic and the North Pole, the same-sex repulsion, and the Antarctic sucking the North Pole, etc., make people feel big when they listen to it. After a while, people will be fainted...

However, the more this happens, the more people in the tribe feel that the Son of God is powerful and unfathomable!

Think about it, too, if it is what the son of God said, and others can easily figure it out, how can it be done?
