Gawain abandoned his plan to build Earth's classic steam engine after discovering that boiling water could not produce enough steam power.
But this did not mean that he gave up his goal of creating a universal, reliable, and simple power machine.
He still remembers how in his home world, industrial mass production razed all inefficient production models including manual workshops, and how the roaring machines pulled the entire human civilization from The land rises and enters the space age. In a factory, raw materials are poured into the workshop like flowing water, and tons and tens of thousands of products will spew out from the end of the machine cluster. The power of machines can completely change the way a society operates. They can crack mountains and crack rocks. They can also reclaim seas and plains. They can be more powerful, precise, efficient, and tireless than any single human individual. These qualities that surpass natural humans exactly reflect the true power of human beings.
That is the power of thinking and creation.
Of course, Gawain is also very aware of the side effects of industrial production, such as pollution and the pressure on natural resources caused by excessive production efficiency. However, the problem can be solved, but survival is not negotiable, just like human beings. Diseases can be cured, but it would be unreasonable for you to directly refuse to reincarnate in order to prevent illness...
So whether it is to survive natural disasters including demon tides, or to keep yourself in this world To make life more comfortable in a backward world, or to understand the truth of the world, Gawain must light up the technology tree. In order to light up technology, the most basic thing is to solve the problem of power.
Steam propulsion is a dead end, but many of the rules of this world in the macroscopic realm can still be used. Gears can be used, levers can be used, waterwheels can also be used, and thanks to the power of magic, Granted, many technological developments that cannot be skipped on earth and require slow accumulation can be advanced here by leaps and bounds, such as high-quality steel smelted based on magic technology, such as various types of steel that are different from those on earth, but have extraordinary properties. Alloys and crystals——but these things have not been fully used in this world.
In other words, people in this world have indeed discovered the usefulness of these things in their own technical routes. After all, people from other worlds are not stupid - it’s just that due to the limitations of the world view, they simply can’t Thought of other ways to use these things.
Gao Wen looked at the cylinder structure on the drawing. He had already marked the structure with a cross. Now he wanted to think of a substitute to replace steam to power the entire device.
What he can think of is still the work done by expansion, or the work done by high-pressure airflow, but where do these "sources of power" of high temperature and high pressure come from?
He once thought about the Rebecca Crystal - to put it bluntly, an explosion is also a kind of expansion. As long as it is used properly, the power of the explosion is also a kind of power. The essence of the internal combustion engine on the earth is actually running in the cylinder. Continuous "safety explosion" (deflagration), then Rebecca Crystal madeCan the completed explosion also be controlled and guided to become a driving force?
But after understanding the principles of those crystal explosions, he had to give up this idea.
The Rebecca crystal that uses magic to produce explosions is completely different from the gunpowder on earth, and the two "explosion" processes are also completely different.
The explosion produced by Rebecca's crystal is essentially a "spell". The power of the magic circle activates the energy in the crystal and forms an independent spell casting process. The effect of this spell is " "Explosion", so before impact and expansion, the first thing Rebecca's crystal produces is actually a spell effect. So what will happen if such a crystal is stuffed into a cylinder and triggers the detonation circle?
The cylinder will be detonated as an alchemical product...
Of course, Gawain can make the cylinder extremely strong and thick, even so strong that it cannot be exploded even if it is filled with crystals. To the point where it is open, can the explosion magic inside it be used to promote it at this time?
No, it will blow up the more fragile connecting rods, pistons and the like as casting materials. As long as these things are within the casting range of the magic circle, they will not be spared.
What if everything including the connecting rod, piston and so on were extremely strong and would not be blown up, but only the crystal participated in the magic reaction?
Well, this device may really be able to do work at this time, but its size will be extremely huge - because the outer diameter of its absolutely explosion-proof outer wall must exceed the casting range of the detonation circle, Depending on the equivalent size of its core, this outer wall is most likely to be a sphere with a radius of several meters to tens of meters, and it cannot shrink at all - once it shrinks, part of the outside of the device is within the range of the explosion spell, then the operation If the operator is standing nearby, the operator will be detonated... Human beings are one of the best magic materials.
Even if there is no operator nearby, the device itself will be enveloped in a continuous explosion, detonating anything near it.
This is completely useless!
And because the "explosion" of this world is so special, Gawain gave up the idea of using Rebecca crystal to make guns, at least he gave up the idea of using this crystal to fire. : He can't put these crystals into the gun chamber as propellant, because these propellants will directly create an explosion in the spell effect area during the casting process. By then, the gun will be fine, and the person who fired it will definitely explode. The one standing next to him should also have exploded...
Then what should he use to do his work?
Steam doesn't work, explosions don't work, fuel... He hasn't heard that anything similar to oil exists in this world yet.
And we have to take into account the processing accuracy issues in today's world. Even if he designs a usable prototype, it will be a problem if the blacksmiths can't hammer out suitable parts.
But to be honest, this aspect is not what worries him the most: he still remembers that he is the kingThe mithril safe that was unearthed from the old house, the complex magic lock in the safe is actually a very sophisticated mechanism, and the person who makes such a mechanism is not an ordinary blacksmith, but a person who specializes in processing magic items and has a higher status than the blacksmith. Runesmith.
Rune craftsmen are equivalent to blacksmiths and carpenters who have received advanced training. Although they do not have the ability to cast spells, they have some knowledge in the field of magic. They are usually trained by magicians to create magic props for themselves. of "workers".
They are skilled in their craftsmanship, able to create things more sophisticated than ordinary ironwork, and know how to work safely with a variety of magical materials.
Although the number of rune craftsmen is small and it costs a lot of money to build things (mainly the cost of magic materials), if they can help them build a prototype, it is still worth it.
Among the one hundred technicians from the royal capital, there are rune craftsmen...
While Gawain was thinking, two familiar auras appeared in his perception. , the curtain of the tent was opened, and Rebecca and Hetty walked in together.
"Ancestor, are you looking for us?" The two said almost in unison.
"Yes," Gawain didn't waste any time and pushed the drawing forward directly, "Bring a chair and sit here. You guys can take a look at these things."
Rebecca He ran to move a big chair, and Hetty made a casual move, and grabbed a chair in the corner of the tent and flew towards it - leaving Rebecca stunned for a moment. .
But soon, Miss Tietou was attracted by the drawings displayed by Gawain.
"What is this?" Rebecca's eyes sparkled, "There are many wheels and connecting rods...is it also a waterwheel?"
"No, it is a kind of water wheel. ...a machine that can generate power," Gawain explained casually, "I have limited ideas and would like to hear your thoughts - you can imagine a machine that can produce stable and reliable power driven by the most basic magic unit. Power, for example, makes the wheel rotate continuously, such as driving the hammer to move up and down. Look at these connecting rods and wheels, and this structure - it is called a crankshaft. These things can convert linear reciprocating motion and rotational motion of the wheel into each other... ”
Gawain patiently explained his ideas, Hetty became thoughtful as he listened, and Rebecca’s eyes sparkled: she had a strong interest in these unconstrained designs. interest!
The concept of mechanical devices that rely on magic power to operate is actually not new. This world with extraordinary power has natural advantages in many aspects. Naturally, there are also many "super-era" in Gawain's view. "things, such as the golems created by magicians, the automatic doors activated by keys like those in the mountain treasure house, and the magic locks that can identify the user's identity that were seen in the royal capital. These are all considered magic devices. Applications, many of which can even be described as “black technology”.
But Rebecca felt instinctively that GaoThe "magic power mechanism" proposed by Wen is completely different from those things.
Most of its structures are intuitive and direct mechanical structures that do not require the involvement of magic power.
Its function and purpose are extremely simple, which is to provide power, and this power is to prepare for the next level of machinery.
It is normative, standard, and clear. It abandons all the parts that allow craftsmen to "play freely" and replaces them with digital indicators as precise as magic rules, striving to achieve them in the most reasonable and concise way. purpose, unlike those traditional rune craftsmen or mages who would put a lot of patterns on the magic items they create, and also go to great lengths to hide the really useful runes in complicated encrypted patterns. Among them, I was afraid of being seen and understood.
Rebecca thought hard for a long time, and finally a word that Gawain often said to herself came to mind: universality.
Just like Magic Network No. 1, this device is also "universal".
It is not designed as a treasure or work of art, but like those Rebecca crystals fired in the kiln area - what is required is large quantity and sufficient, solid and reliable.
Gao Wen finished explaining his thoughts, and finally pointed to the forked cylinder structure: "Now there is just one step left: it needs an initial power source to allow this 'piston' to move. Get up, I have thought about letting the expanding gas complete this process, so I designed this sealed 'cylinder', but you don't have to be limited by my thoughts - from a magic point of view, which spell do you think can create a... With an energy supply, it can push forward continuously and cyclically?"
Rebecca grabbed the chair and shook her body: "Carve a super small hurricane circle inside and blow hard? ?"
Hetty also frowned and thought seriously: "It's not realistic. The hurricane formation is too complicated, and the airflow it can induce in a closed environment is limited..."
As she spoke, she condensed a translucent plastic hand beside her, but then dispersed the magic: "It would be simple to use the plastic hand to push inside, but unfortunately this is a very special place. There is no corresponding magic circle for the spell, and...it feels weird to have a plastic hand pushing it around inside the machine."
"Huh, plastic hand..." Rebecca turned. After thinking about it with his eyes closed, he suddenly seemed to have some ideas, "Yes, you don't have to use airflow... you don't even need this thing called a 'cylinder'?"
Looking at Rebecca getting more and more With his eyes getting brighter and brighter, Gawain couldn't help but feel happy: The silly roe deer is going to make a meritorious deed again! ?
Hetty also became curious: "What did you think of?"
Rebecca gestured happily: "Aunt, do you remember that there was a spell I couldn't learn? Yes..."
Hetty: "Except for the fireball technique, which spell did you learn?"
"No, at that level of magic, what did you think of it at the beginning?I'm afraid that no matter how stupid I am, I will definitely be able to learn it," Rebecca waved her hands vigorously. "Later, I secretly drew runes on my gloves and pretended that I could cast spells, but in the end I was hung up and beaten by you and my dad..."
Gawain: "..."
Does this girl have to be so happy when she says this?
And Hetty has obviously thought of Rebbe? What is that “trick” that Ka is referring to: “The repulsion trick? ”
