"Hey, Brother Kishiko?"

At the same time, the Chuanshui Bank is in business, and the people of Rizhao Village are also busy.

He'an was about to go and meet another big deposit customer in person, and wanted to keep him from transferring the deposit, and was already preparing for a carriage trip, and was in the study, drinking water and waiting.

In addition to the riverbank in the study, there are mountain peaches. Shan Tao is a lively girl, but she loves to read very much, so she read the pamphlets of Mr. De copied by Gu Chuan in the study. She happened to see Gu Chuan's annotation on the booklet on the calculation of clock craftsmanship, and she thought that Gu Chuan might now be under the ubiquitous crown that she had never met but was everywhere in Sunset City, and she couldn't read it anymore, no matter how she couldn't read it.

She looked up and called out to the riverbank.

The riverbank turned his head and looked at the mountain peach:

"What's wrong?"

Shan Tao is in the Sichuan Bank, she is responsible for training girls, she is considered spiritual, uniting the female apprentices, establishing many norms, and it can be regarded as a bit of management spirituality.

Shan Tao propped up his side face, thinking that the fate of the big guy was hanging on one person's body, he couldn't help but sigh in the eternal twilight:

"What are the three gifts that Brother Chuan brought? He didn't even tell me, you know? ”

The banks of the river are known.

"Didn't he say it? That might be for the sake of secrecy. The main thing is that those few things can cost money...... Come to think of it, I remember one of them being a big clock, and as soon as it was turned on, there was a mechanical figure in it that would start writing. ”

Yamamo's eyes widened.

"It's ...... I remember that he had been doing it for a long time, and it did take a lot of money. ”

"Exactly."

"What about the others? Does it cost money too? ”

"The other ones cost money, too! For example, the second piece was made by melting a lot of color-changing stones, and I still don't understand the principle, but I heard him say that this is an interesting property of color-changing stones at high temperatures. ”

"Melt Colorstone...... Even if the color-changing stone is not minted, it is very expensive! ”

Yama Tao was taken aback, remembering the cost of buying chameleon that had been taken off her account before, she originally thought that this was a manifestation of the so-called "anti-inflation" and was hoarding supplies. It turned out to be melted and used to make something else......

Yamamoto asked again:

"Did Brother Chuan say what this nature is?"

Riverbank stood up, first looked at the carriage outside to see if it was coming, and then recalled:

"He said it, but I didn't get it. He asked me if I had noticed that when the colorite turns black, it heats up very quickly and melts quickly. I asked him what it meant. Ogawa said...... It has been recorded in the process that the color change stone is similar to that of other reference metals in the first hour, except for the color change, in the same heating environment of the same quality. But from the second hour onwards, the color-changing stone will quickly absorb heat and blacken, and melt, and when it is not heated, it will quickly exothermic and cool without condensation. He said it was strange, and it was the strange nature of the color-changing stone at high temperatures. ”

As he said this, the riverbank saw that the carriage had arrived, and he hurried away.

At that time, the sun was about to disappear completely behind the clouds, and the shadows of the stepped pyramid-like buildings were merging with the shadows of the hemispherical buildings in front of them, and dissolving into the darkness of the sky.

In the Central Prohibition Palace, the time of the writer's clock has ended.

All eyes converged on him.

The writer's clock is also a great wonder in Gu Chuan's hometown world, which is a kind of automaton puppet made in the development of pure machinery and clocks in the Western European world in the eighteenth century, and is mostly used as a European court performance.

There is no other use, but only the extreme of useless mechanical skill.

But this kind of technology and design alone is enough to impress the people here.

The guards standing in the circle had their heads raised, but now they were all lifted even straighter, so that they could see the details of the writer's clock while standing still.

"Your Majesty asked, is this a strange thing?"

The girl standing under the glass veil under the mural whispered softly, and in her eyes, Gu Chuan also saw surprise.

"It's not a strange thing." Gu Chuan said, "This is a purely mechanical creation. ”

There is no electricity, an internal combustion engine or a steam engine, nor any unknown strange power.

"With more than 6,000 parts alone, a combination as complex and extreme as a clock, a longitudinal cam group is formed by customizing the internal forty cams, and when the winding wheel is wound and the cam set begins to move, the device of the hand will interpret the shape of the cam with the movement, which will be converted into arm movements, so as to write words."

This is not a creation that can be completed in Rizhao Village.

Instead, Gu Chuan relied on the channels accumulated in the craft chapter, searched the whole city, and only looked for excellent mechanical craftsmen, which created the work.

A giant clock measuring more than two meters is located in the middle palace. The automatic villain made by the machinery above is motionless when he finishes writing and reporting.

From the hair to the clothes, from the fingers to the feet on the floor, the finesse is the limit of that craftsmanship.

The girl above didn't say a word.

And the attendants below didn't dare to say much, only lowered their heads and raised their eyes.

The young man smiled freely:

"That's the first magical thing I'm going to dedicate, the 'Writer's Clock.'"

After a long while, the messenger girl said:

"His Majesty is very satisfied, and His Majesty said that although it is not a strange thing, it has long been far superior to ordinary strange things, but it is the wisdom of human craftsmen, and it should be praised."

"It's my pleasure, Your Majesty."

Gu Chuan lowered his rebellious head again.

The hour hand of the second layer of the writer's clock slowly turned, and the guards and attendants around them all cast their complicated glances at Gu Chuan.

The candlesticks are bright, and the light lingers among the mirrors, illuminating the city and agriculture in the murals that His Majesty loves, the velvet curtains inlaid with precious stones, and the statues of the guards and the citizens of the sunset city.

The one-eyed mural stares at the people below. In the slices of gems or crystals embedded in them, you can see the reflection of the writer's clock.

The girl's facial expression was far away, and Gu Chuan couldn't see it clearly. She asked quietly:

"Your Majesty asks you, what is the second miraculous thing you want to offer?"

"And ask the two attendants to take out the box from the second box and place it in front of the writer's clock."

Gu Chuan pointed to another big box and said politely.

The maid nodded, and the two attendants obeyed the order, took out a box of nearly the size of an adult from the box, and together they carried it to the writer's clock.

It is exactly the same as the mechanical villain of the writer's clock.

Gu Chuan nodded at the attendants, and the two attendants retreated flatteredly. Gu Chuan then turned his head and looked at the eye on the mural.

"Your Majesty, can I say something first?"

The girl in the glass gauze dress who had spoken said:

"Your Majesty said, yes."

Gu Chuan paced and said unhurriedly:

"Actually, I've had a puzzle since I was a child. I think you've all seen this phenomenon. What kind of phenomenon is this, and that is...... Evaporation of water. ”

"When the temperature is very high, like when I boil water, the water turns into water vapor. This phenomenon is incomparably common in our great divine nature. ”

The maid who led the way was listening carefully, and when she heard half of the place where Gu Chuan was staying, she suddenly realized that unconsciously, the guards who were originally guarding the four edges of the middle palace all raised their heads, all listening to the young man's speech, or they were curiously observing the writer's clock.

And the young man stood up and began to give an example:

"For example, on a sunny day, there seems to be a layer of fog on the surface of the lake, and in the woods in the morning, there is also a layer of fog. After washing, I splashed the water on the ground, and the water seemed to not flow away, but it slowly disappeared. Put a glass of water on the weighing table, and after a while, you can find that the quality becomes lower. Ah, these are the evaporation of water by the sages, the process by which water becomes water vapor as the temperature rises. ”

"So I was thinking, what would happen if it was cooler? I asked my mother and she replied that it turned back into colder water. So what about the assumption that it's colder, colder? My mother couldn't answer, only colder, colder water. ”

- Isn't that so?

Several of the attendants widened their eyes in bewilderment.

This is also the answer their mother told them when they were children.

But they were so well trained that they could not make a sound, and they did not dare to make a sound, so they could only keep their heads down and look cautiously, as if they were listening to a tale of the Arabian Nights.

"But after experimenting, I found out that this is not the case......"

Gu Chuan opened the box.

The outside of the box was wrapped in a large quilt, as if it was for heating. There is insulated rubber inside, and when the insulated rubber is disassembled, it is still a rubber box.

His Majesty asked, why did you make two rubber boxes?

The girl standing in front of the mural blinked, and said as if she was talking.

Gu Chuan smiled.

"It's for heat preservation and cushioning, so as not to shatter, crown."

Rubber has the function of heat insulation and also has sufficient air tightness. But the two-layer rubber box is really not just for this, the mystery is that Gu Chuan extracted the air between the two layers of rubber box, forming a temperature-insulating vacuum.

But this is difficult to explain. Among them, the concept of air is applied first, followed by the concept of vacuum and nothingness, and then the concept of heat conduction and radiation.

Gu Chuan thought that he didn't have to explain it so clearly.

Then he uncovered the rubber box.

At the moment of unveiling, a cool and refreshing cold air bubbled into this warm room, like a cold current rushing into the warm sea.

The guards woke up from the cold, the attendants opened their eyes wide, and secretly surrounded Gu Chuan in the middle, and the group saw that inside the rubber box was a glass box.

In the transparent glass, there is a large thing that is close to transparent, like glass, but not glass, like crystal, but not crystal.

Because of the optical refractive index, anyone can identify it.

There were a lot of rough, thorny things on top of it, as if water beads were coming out. The surrounding lights fell on this huge transparent object, and immediately refracted the light, glowing with a glow-like color.

Gu Chuan stood next to the transparent stone and smiled cleanly.

"It's ...... Diamonds? ”

For the first time, the messenger girl who had never changed her face after seeing the scribe clock showed a surprised expression.

Sunset City had diamonds, huge diamonds, the size of a man's hand, but none of the citizens and guards present had ever seen a diamond the size of half a human body.

Gu Chuan said:

"It's certainly not a diamond, Your Crown. I've been poor all my life, where can I find such a large diamond! ”

Then this is a kind of mysterious thing that Sunset City has never seen before, which makes the people around it full of curiosity, and ...... Fear.

Suddenly, the maid cried out:

"Protect Your Majesty!"

Before the words fell, all the attendants and guards listened to the words and took steps, formed a formation, took a step towards Gu Chuan, surrounded Gu Chuan in the middle, and left very little time to explain to Gu Chuan.

The maid who led the way was also secretly annoyed that the people of the inspection department dared to put such a big thing into the inner city, and hurriedly called her subordinates to inform more city guards. Where has Gu Chuan seen this kind of battle, standing in place, he didn't dare to move, for fear that he would be beheaded by the guards if he made a move. It's just that he is confident.

"Rest assured, this thing isn't a strange thing."

Gu Chuan said to them.

The mural on the stage and the girl who spoke were silent. Only the attendant sternly questioned:

"Do you dare to touch it?"

Gu Chuan replied unhurriedly:

"Of course you dare, not only dare, any of you can touch it if you want. Because the preciousness of this thing lies in the difficulty of preserving it in Sunset City, if it weren't for the long-term White Dew Festival, I would definitely not be able to keep this thing. ”

The guiding maid is obviously not just a simple character, I am afraid that she can be regarded as the leader and chief attendant of the attendants.

She looked at the messenger girl.

The messenger girl covered her mouth with her hand and whispered:

"Your Majesty said, 'Let him touch it, and then let the other two of our men touch it, and the others will be on guard."

For the guards and attendants, this is tantamount to facing life and death.

Like the poison test of food, their hearts are filled with the fear of being chosen.

But the maid ruthlessly chose two of them.

Gu Chuan didn't care what they chose, and opened the glass lid directly. As a result, the cool air and cold air began to rise more and more, making the surrounding people more nervous, as if facing a great enemy.

This could be an amazing curiosity!

They haven't heard of the strange thing that can be cooled!

Two people who thought they were unlucky ghosts stood with Gu Chuan, looking down at this strange transparent mass in fear. Gu Chuan put down his hand without any guilt.

And the two men nervously broke out in a cold sweat with their heads and hands, and the sweat fell on the ice with their hands.

"It's so cool!"

One man shouted.

Then, after a short while, he withdrew his hand and cried out:

"No, it's hot!"

The guards were even more nervous, and the weapons in their hands were almost around the neck of the erect young man.

Gu Chuan didn't say a word, only put his hand on the ice cube for a while, only a pair of clear eyes were still staring at the mural and the girl under the mural, and saw the curiosity on the girl's face.

The hearts of the two people who were also touching were intertwined with all kinds of terrible feelings, and they could not describe the encounter. It's obviously very cold, but if you touch it suddenly or for a long time, it will feel very hot.

But it's hot, or it's cold, but it's not changing.

After touching for a long time, they suddenly found that their hands were all clean, dewdrop-like water stains.

When they saw the big transparent thing in a blink of an eye, they saw that the surface they had touched had melted a shallow layer and water was coming out. The unlucky ghost attendant muttered in amazement:

"What the hell is this...... Where is the curiosity? ”

"It's not a strange thing."

Gu Chuan shook his head, straightened up, and smiled confidently:

"It's ice."

It's also water...... In a very cold and cold situation, it will become something.

"It's also the second gift I want to give to His Majesty."

And the sound of hurried footsteps came from outside the door.
