Chapter 1214 On the Benefits of Reading Novels (2 in 1)

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

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

That is to say, there are ten degrees between each space.

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

It's just that the compass that I'm trying to make for the first time is still a bit small. If you continue to draw it with a quill pen, it will appear too bloated and messy, but it is not easy to identify.

But these are minor problems, as long as you want to be meticulous, then when you make it later, you need to divide and plan carefully.

Now that this production is successful, then these are small problems.

There is a small hole in the middle of this circular cardboard piece, which can just fit on this small circular bronze column, and its size matches the circular bronze base below.

The underside of the circular piece of paper has already been coated with a layer of isingas gelatin, and after being pressed down, it just meets the bronze bottom below.

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

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

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

After some debugging, I got another thing like a 'hat' and put it on top of the bronze pillar to fix it.

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 pointer of the compass from slipping off the bronze column after the person holds the compass upside down in the future.

This time before assembly, Han Cheng made some adjustments and experiments in advance, trying to do everything as well as possible.

So after this set of procedures, after assembling these things, there is no embarrassing 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 Han Cheng tried to dye red was already pointing firmly to the same target 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 went to look at the effect of the compass.

The purpose is to test the quality of the compass.

As far as the current situation is concerned, the quality of the newly manufactured compass is still very good.

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

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

Seeing this, Han Cheng couldn't help showing a satisfied smile again.

In fact, this compass still has some shortcomings.

The downside is the lack of a transparent cover.

If you get a transparent cover to seal it, it will be perfect.

In this way, this transparent cover can be used to protect the parts in the compass, and the damage from external forces will be 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, and it is useless to think about them.

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

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

Although there are no transparent covers that are convenient and beautiful to use, they can still provide some protection after all, which is better than no cover.

Holding this soft cover covered with leather, no matter how you look at it, it looks a little awkward, Han Cheng couldn't help but feel a little moved inside.

Perhaps, in addition to using this kind of leather cover, our own tribe can really make some transparent things 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. It is not uncommon to see high-quality jade and rough jade, and a pile of them is piled up in a house.

Plastic is not good either. Although it is very common in later generations, and once became an important part of pollution, at this time, Han Cheng wants to experience this kind of happy trouble, but he can't feel it...

What Han Chengzhi was most excited about was 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 took advantage of the opportunity to reap the amazement of a large number of people, and at the same time, there was a lot of rapid improvement in wealth and status.

In the later generations, Han Cheng was a person who liked to read novels more. At the beginning, he was Xianxia, ​​and then slowly changed to history, and then he basically read history.

Many historical novels have one characteristic.

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

These things will promote the development of the plot, and can also bring a lot of big gains such as pretending to be aggressive, getting rich and so on!

As a person who has been immersed in such novels for some time, Han Cheng thought of something about glass manufacturing at this time, which is also reasonable.

After all, there are all kinds of strange knowledge in these books.

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

Even able to quickly step into the industrial age!

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

As small as needles and threads, mosquito coils, toilet water, bras, aunt towels... as large as red cannons, flintlock guns, battleships... and so on, they are all-encompassing and diverse!

Of course, in addition to these, there are also many poems and songs that are specially used to pretend to face and improve fame.

But Han Cheng doesn'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 today.

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

In such a case, nothing will be received except for a circle of hominid question mark faces.

As for "the head of the willow on the moon, people make an appointment after dusk" "Guan Guan Jujiu, in the river island. A fair lady, a gentleman loves you. ’ and so on, the effect at this time is really not as good as a sentence like ‘I want to sleep with you and have a baby’...

According to a historical novel that Han Cheng once read, glass is fired from sand.

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

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

He himself can't remember clearly, whether he forgot it, or it was not written in the novel.

But just these are enough.

After waiting for a while, I will tell Hei Wa this guy who wants to throw everything into the fire to burn these things, and let him study and explore.

Today's Heiwa is already proficient in pottery, porcelain and mold making.

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 be very happy to accept this matter!

After all, this is a thing that has a certain relationship with the kiln, and after it is finished, it is also a test of one's skills.

There are many people watching around. After all, these days, as Han Cheng handed over the various tasks of making the compass, and personally cooked for the trade team headed by Han Yousan, as a reward, The fact that the people in the tribe brought back very useful magnets for the people in the trade team, and that the Son of God was going to use these things to make a very magical compass has already spread among the tribe.

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

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

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

Visual fatigue has occurred.

It is completely different to follow Shenzi to watch Qi Qi.

Because Shenzi can always come up with a lot of strange things, people can't help but be amazed by it.

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

I feel that this time I waited for others to watch here for nothing, which is really worth it.

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

If I were doing live broadcasting in this era, judging from what everyone is showing now, it is conceivable to make a lot of money.

Of course, it is also very likely to look like this - you received a pile of dried meat as a reward from a pine branch, and you received two dried vegetables as a reward from a stone...

Not all of the people standing here watching the excitement are watching the excitement here, and some people are here with thinking and a strong thirst for knowledge.

It's like preparing the witch's stone that has been prepared for many years.

Speaking of this matter, Han Cheng would sometimes think amusedly that one day Shitou would say with a mournful face, "How can there be forty years of preparatory witches in this world?"

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

After standing here and watching for a while, he finally asked Han Cheng for advice.

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

When Shishi opens his mouth, he will pick up the thick ones, and when he asks, he can get to the point.

After thinking for a while, Han Cheng smiled and said to Shi Shi: "This is because the whole earth is a big 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.

The same magnet, after you break it, it is impossible to connect it from the broken place without relying on external forces such as squeezing hard with your hands.

Moreover, even if they are forced together by hand, as long as you let go of your hand, they will separate, then change some directions, and then suck together.

The reason for this is that magnets have a property that opposites attract and likes repel.

The broken magnet has changed from a whole to two individuals, and naturally there are same-sex and opposite-sex distinctions.

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

Two south poles facing each other will repel each other, and one south pole facing an north pole will attract each other.

As for the pointer of the compass, although it is made of iron, it has become magnetized and possesses the properties of a magnet after my operations.

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

Under the action of same-sex repelling and opposite-sex attracting, the pointer will naturally rotate to become north-south.

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..."

The small class of Shenzi of the Qingque Tribe started again.

Han Cheng, the god son of the Qingque tribe, based on what he knew about magnets and compass, and then added his own understanding, and the understanding ability of the tribesmen present, and told the stone as easy as possible some.

When Han Cheng started speaking, all the people present were silent and listened very carefully.

However, the same words have completely different effects on the ears of different people.

Just like Shitou, after Han Cheng finished speaking, it didn't take long for him to understand all these things.

But even though more people were present, they knew the meaning of every word Han Cheng said, but after linking them together, they couldn't understand it, and they didn't understand anything.

Antarctic and north poles, same-sex repulsion, south pole attracts north pole, etc. It makes people feel dizzy when they listen to it, and it will make people dizzy after a while...

However, the more this happened, the more people in the tribe felt that the Son of God was powerful and unfathomable!

If you think about it, if you and others can easily understand what the Son of God said, then what's the matter?
