The carriage drove through the wind and snow and headed out of the city.

"Crunch, crunch, crunch." The wheels crushed against the snow with a loud sound.

In the not small carriage, there is a smell of lo-mei.

Xiao Chubby Dun sat in the carriage, the oiled paper in his arms that packed the braised chicken was spread out, he picked up a chicken leg and feasted on it, and looked at Sister A and Zhu Zhan while eating.

He didn't expect that this person who suddenly met and was willing to listen to his nonsense actually knew Sister A, and the relationship seemed to be unusual.

Hmph, there must be something wrong with these two people! Little Chubby muttered secretly in his heart.

"You're going out of town?" Zhu Zhan was the first to break the silence and asked.

Seeing Zhu Zhan Rong asking, Jing Yu said "um" lightly, and then said: "It's snowing heavily today, and Ah Shuo will take him out if he wants to go out of the city to enjoy the snow." After saying that, she was silent for a while, and then said, "What about you?" ”

At this time, Jing Yu faced Zhu Zhan Feng with no previous nature, and there was a kind of restraint and unnaturalness invisibly.

Thinking that the boy in front of him, who is a few years younger than himself, is likely to become his husband one day in the future, his heart that was calm before has become beating again at this moment, full of strange emotions that he has never had before.

Zhu Zhan also noticed that the Jing Yu he saw this time seemed to be a little different from the last time in words and deeds, but he didn't think much about it, just smiled: "Like you, I also came out for a walk and enjoyed the snow by the way." ”

What can you do without appreciating the snow? In ancient society, he didn't have any other entertainment activities except for cultivation, and it was not bad to see the pure natural snow scene.

Of course, he could also engage in pornography, but as he cultivated, he found that he didn't seem to pay much attention to this matter.

Well, of course, it's not that it doesn't work, and it's not that there's a problem.

A body that has no feelings, a friction that cannot have a soul spark, and afterwards the heart is all hollow, which is not very interesting.

Suddenly, Zhu Zhan was attracted by an object placed in the middle of the carriage, and saw a cylindrical iron bucket about 40 centimeters high and about 50 centimeters in diameter next to Jing Yu's seat.

"What is this?" Zhu Zhan pointed to the iron bucket and asked.

Jing Yu pursed his lips when he saw Zhu Zhan asking and said, "I asked the blacksmith to make a water stove." ”

"Water stove?" Zhu Zhan was surprised and said, "Eh, don't you have a kettle at home?" ”

"Hmph." Jing Yu laughed amusefully at Zhu Zhandong's words, and the restraint at the beginning gradually relaxed, "Naturally not." ”

Then, Jing Yu told him about the idea that he had always wanted to improve the water-to-large spinning wheel, as well as the steam power that he accidentally discovered when boiling spices more than a month ago, and his experience of many failures.

"Unfortunately, the kettles at home are too fragile, and if you boil water under complete sealing, you will either be torn or burst." Jing Yu said, his brows furrowed slightly, and he seemed to be very distressed.

However, after listening to her words, Zhu Zhan was stunned.

Boy! Are you going to build a steam engine in Daming?

Thinking about it, Zhu Zhanyuan's heart moved, and he reached out to open the lid on the special water stove, only to find that the lid had not been picked up.

"Huh?" Zhu Zhan was surprised, is it so strict? Of course, he didn't use his cultivation, nor did he burst out of his physical strength.

"The lid is not fastened." At this time, Jing Yu suddenly squatted down, put his hands on the stove lid, and then began to rotate to the right.

Is this a nut and bolt combination? Zhu Zhan looked at Jing Yu, who was seriously twisting the lid of the furnace in front of him, opened his mouth, and said, "This is what you think this is?" ”

Zhu Zhanyuan was really surprised, who would have thought that she would come up with such a combination of nuts and bolts.

It won't be more than a hundred years before this thing appears, right?

"Be careful, not light." At this time, Jing Yu had already unscrewed the lid of the furnace and handed it to Zhu Zhan with both hands.

Zhu Zhan also stretched out his hands and took it.

"Hey, it's seven or eight pounds." Zhu Zhan looked at the lid of the furnace, and below it was a raised solid iron pillar with some threads on it. Looking at the mouth of the water furnace, there are also corresponding deep concave threads.

Obviously, it's a bolt and nut combination hammer.

"When I watched a carpenter drive a nail into the solid wood, I wondered, if it's iron, can there be a nail into it?"

Jing Yu said, with a bright smile on her face, as if the mention of these would make her feel happy.

"After many attempts, I found that I could punch holes in the iron in advance and chisel scratches on the edges of the holes, and then when I made the nails, I made some embosses on the nails in advance that corresponded to the scratches."

"It's a pity that it's easy to do rough, but it's very troublesome to do fine, but it's finally successful. After that, it only takes continuous fine grinding to create this nail that can be driven into the iron. ”

Looking at Jing Yu in front of him, squatting in front of the water stove, like a baby, with both hands on the water stove, Zhu Zhan praised and said: "Can you have a name?" ”

Hearing this, Jing Yu was stunned for a moment, and then said with a smile: "Not yet." ”

"Well, do you think these patterns look like the patterns of the snail shell?" Zhu Zhan pointed to the pattern of the furnace mouth.

Jing Yu also looked at it curiously, his eyes lit up slightly, and said, "Hmm." As she spoke, she lowered her head and began to think, "From nails......

"Da-da-da-da." A pair of white palms rested on both sides of the mouth of the water stove, and a few slender fingers like green onions continued to pat gently, and then suddenly stopped, raised his eyes to look at Zhu Zhanyuan, and said in surprise: "Why don't you call it a screw?" ”

"Ahh Zhu Zhan opened his mouth, then nodded with a smile and said, "Screw, I also have this intention." ”

Well, it's called screws, and there's nothing wrong with it, screws, bolts.

"Thank you." Looking at Zhu Zhandong's gentle eyes, Jing Yu's upturned face showed a heartfelt smile, and his bright eyes were about to squint into crescents.

"Huh." The little chubby dun Jingshuo, who was eating chicken legs, pouted, looked at the chicken legs in his hand, and suddenly felt tasteless.

Zhu Zhanyuan smiled and continued to look at the furnace lid, the top of which was a one-piece forged protrusion that could be linked to some conduits and other things.

"As long as this water furnace is filled with water, grilled on the fire, and the protruding mouth above is blocked, a huge ......amount of energy can be formed inside it," Jing Yu said seriously.

"At this time, a very strong water vapor will form inside the water furnace, which can exert great power if they are full of explosive power."

"It's a pity that I only want to burst out of this energy in an instant, but I can't master this energy and use it for a long time. In this way, it will be transferred to the water-to-large spinning wheel, so that it can continue to drive the water wheel to run. ”

"And once the protruding nozzle is blocked, the water furnace may burst, the risk is too great, there are too many problems, and there are many problems to solve......"

"Once these problems are solved, then this power can even be used in various ways, such as horse-drawn carriages, which may not need horses to pull them."

Jing Yu said, his brows furrowed deeply, and his tone was full of regret.

Tsk, it's really an 'engineering girl'. Zhu Zhan looked at her serious and completely immersed in thinking, and couldn't help but sigh secretly.

"There are too many things that are lacking in the conversion of internal energy into mechanical energy, but it is not only these technical problems." Zhu Zhan said openly.

"Huh?" Hearing Zhu Zhandong's sudden words, Jing Yu was stunned, looked up at Zhu Zhandong, and said, "What? ”

"Hmm." Zhu Zhan sighed slightly and said:

"If you make these large-scale products you said and put them into application, it may need to set off a revolution in Daming, well, the so-called 'revolution' you can understand as a change, a change in the law."

Reform!? Jing Yu's eyes widened slightly, and her breath was subconsciously held, she naturally knew what a change was, "Change the law?" How can it be so serious? ”

Zhu Zhan said that he had a shallow taste of the change here, and did not go deeper, and his voice changed, and he said: "Don't talk about this, it's too far, let's talk about your water stove." As he spoke, Zhu Zhanrong pointed to the water stove in front of him and said:

"If you want to do work with steam energy, you can understand it as pushing the water wheel to work, first you need to have a furnace with enough pressure to ......"

Next, Zhu Zhandong used the largest vernacular way to explain the difficulty of building a steam engine, as well as the basic theories he understood and needed, and also brought some basic scientific explanations.

More than an hour has passed.

The carriage had already stopped at its destination outside the city, and Little Fat Dun had already slipped out of the car under the pretext of taking the coachman to play in the snow.

There was silence in the carriage.

"It's so difficult, but I'm whimsical." After a long time, Jing Yu took a deep breath and was a little stunned.

Her unwillingness comes from her technical powerlessness and her unwillingness to live too short when manpower is exhausted.

Looking at the lost Jing Yu, Zhu Zhandong's eyes flashed, he smacked his lips, and said, "Actually, there is a shortcut to take, which allows you to create these objects you want." ”

A vast world destined to cultivate immortals, what industrial revolution are you playing? What science to consider? Isn't the immortal cultivator fragrant?

With divine consciousness and refining means, as long as you dare to think, you can make spiritual weapons and magic weapons, what kind of precision instruments do you want that can't be made?

And isn't Reiki the best new energy?

And the aura generated by the burning of mutated coal, isn't it just enough to be wasted?

One is based on the premise of the aura energy revolution, and then the refining revolution breaks out, which will be a prerequisite for the construction of the low-level Ming Immortal Dynasty.

As a supporter and beneficiary of imperial power, Zhu Zhandong naturally also had to consider the lives of the people.

After all, it's still the same sentence, the lower foundation, the superstructure is decided!

In the future, not everyone will be able to cultivate immortal refining tools, so these simple and convenient mechanical applications will still be very needed in the future Ming Dynasty.

He needs to come up with some spiritual weapons that can be used as long as he has spirit stones and spiritual energy, which can be clothing, food, housing, transportation, and other aspects.

For example, a chariot driven by spirit stones or spiritual energy.

The manufacture of this chariot can be done by the refiner.

But in the future, maintenance, protection, and use, these need to be simple and easy to understand, so that people who don't cultivate immortals can also use them.

For example, to refine an aura sports car, the repair master does not necessarily have to know how to build a crankshaft or the like, including its principle and so on......

These are all the things of the refiner, but when these things are made, it must be ensured that the repair master knows how to disassemble, install, and maintain them.

The refiner, well, to put it bluntly, in the future, it will be a humanoid machine tool that integrates theory and manufacturing, and you can build anything you want.

What? Sounds hard? This can't be done, what kind of all-round evolutionary immortal cultivator are you still doing? Hurry up and find a seclusion in the mountains and old forests!

These thoughts burst out in Zhu Zhandong's mind one by one.
