After discovering that boiled water could not generate enough steam power, Gao Wen gave up the plan to build the classic steam engine of the earth.

But this does not mean that he gave up the goal of creating a universal, reliable and simple power machine.

He still remembers how in the world of his hometown, how industrial mass production has ruined all the inefficient production modes, including hand workshops, how the roaring machine has drawn the entire human civilization from the land and into the space age. . In the factory, raw materials are injected into the workshop like flowing water, and the end of the machine cluster will spew out tons of tens of thousands of products. The power of the machine can completely change the way a society operates. They can open mountains and cracks. It can also be filled with Haipingchuan. They can be stronger, more precise, more efficient, and more exhausted than any single human individual. These qualities that are above the natural person reflect the true power of human beings.

That is the power of thinking and creation.

Of course, Gao Wen is also very aware of the side effects of industrial production, such as pollution, such as excessive production efficiency pressure on natural resources, but the problem can be solved, but the survival is not negotiable, just as human diseases can heal, but you If you want to prevent illness and directly refuse to reincarnation, you can’t say it...

So whether it is to be able to survive the natural disasters including the magic tide, or to make yourself more comfortable in this backward world, or to understand the truth of the world, Gao Wen must put the technology tree Point it up, and in order to light up technology, the most basic thing is to solve the power problem.

Steam propulsion is a path that cannot be achieved, but many rules of the world in the macroscopic field can still be used. Gears can be used, levers can be used, waterwheels can be used, and thanks to the power of magic, many cannot be on earth. The technological developments that are skipped and need to be slowly accumulated can be directly jumped forward here, such as high-quality steel smelted based on magic technology, such as various alloys and crystals that are different from the earth but have excellent properties. Things have not been fully exploited in this world.

Or, people in this world have indeed discovered the usefulness of these things on their own technical routes. After all, outsiders are not stupid. However, due to worldview restrictions, they have never thought of using other methods to use these. thing.

Gao Wen looked at the cylinder structure on the drawing. He had already drawn the structure on the fork. Now he wants an alternative to replace the steam to power the entire unit.

What he can think of is still expansion work, or high-pressure air work, but where do the "sources of power" of these high temperatures and pressures come from?

He once thought that the Rebecca crystal 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 a continuous "safe explosion" in the cylinder (deflagration). ), then, can the explosion caused by Rebecca crystals be controlled and guided, thus becoming a driving force?

After learning the principles of the crystal explosion, he had to give up the idea.

Rebecca crystals that use magic to create an explosion, and gunpowder on Earth are not a thing at all. The two "explosions" process are also very different.

The explosion produced by Rebecca Crystal is essentially a "spell". The power of the magical array pushes the energy in the crystal and forms an autonomous casting process. This spell effect is an "explosion", so it is in shock. Before the expansion, Rebecca Crystal first produced a spell effect, so if you put such a crystal into the cylinder, what would happen if you trigger the detonation array?

The cylinder will be detonated as an alchemy product...

Of course, Gao Wen can make this cylinder extremely strong, extremely thick, even thick and thick enough to fill the inside of the crystal can not be opened, then the bursting magic inside it can be promoted?

No, it will blow up the more fragile links, pistons and the like as a casting material, as long as these things are within the range of the spell's cast.

If the connecting rod piston and so on are all very strong, they will not be blown up. Only the crystal participates in the magic reaction?

Ok, this device may actually be able to do work at this time, but its volume will be extremely large because its outer diameter of the absolutely explosion-proof outer wall must exceed the range of the detonation array, depending on the core equivalent size, this outer wall It is very likely that it is a sphere with a radius of several meters to tens of meters, and there is no slight shrinkage. Once it shrinks, some of the outside of the device is within the range of the bursting effect. If the operator stands next to it, the operator will Detonated... Human being is one of the best magic materials.

Even if there are no operators next to it, the device itself will be enveloped in a constant explosion and detonate everything close to it.

This can't be used at all!

And because the "explosion" of the world is so special, the idea of ​​using Rebecca crystals to make guns was also abandoned by Gao Wen, at least giving up the idea of ​​using this crystal to launch: he could not put these crystals It is used as a propellant in the gun, because these propellants will directly create an explosion in the spell effect area during the casting process. When the gun is fine, the person who shoots must be blown up, and the one next to the station should also be blown up. ......

So what should he do with his work?

Steam doesn't work, the explosion doesn't work, fuel... He hasn't heard of the oil-like things in the world.

And it has to take into account the processing precision of the world today, even if he designs a usable prototype, it is also a matter for the blacksmiths to knock out the right parts.

But to be honest, he is not the most worried about this: he also remembers the secret silver safe that he turned out in the old house of Wangdu. The complicated magic lock in the safe is actually a very sophisticated institution. The class is not an ordinary blacksmith, a rune craftsman who specializes in the processing of magical items and has a higher status than the blacksmith.

Rune craftsmen are equivalent to advanced blacksmiths and carpenters. Although they have no ability to cast spells, they have some knowledge of the magic field, usually the "workers" that the magicians cultivated to create magical props for themselves.

Their craftsmanship is capable of creating something more sophisticated than ordinary irons and knowing how to safely process all kinds of magical materials.

Although the number of rune craftsmen is small, it is costly to build things (mainly the cost of magic materials), but if they can build a prototype for themselves, it is worth it.

There are rune craftsmen from the 100 technicians who come from Wangdu...

While Gao Wen thought about it, two familiar atmospheres appeared in his perception, and the curtain of the tent was opened, and Rebecca and Herti walked in together.

"The ancestor (ancestor), are you looking for us?" The two men almost in unison.

"Yes," Gao Wen is no nonsense, pushing the drawings forward directly. "Sit yourself and move the chair to sit here. Look at these things."

Rebecca ran to move the big chair, and Herty took a hand. The hand of the plastic hand grabbed a chair in the corner of the tent and flew here to see Rebecca. of.

But very soon, the little loss of Miss Ironhead was attracted by the drawings displayed by Gao Wen.

"What is this?" Rebecca's eyes sparkled. "There are many wheels and connecting rods... Is it a waterwheel?"

"No, it's a machine that can generate power," Gao Wen explained casually. "My thinking is limited. I want to hear your thoughts. You can imagine that a machine, driven by the most basic magic unit, can Produce stable and reliable power, such as let the wheels rotate continuously, such as driving the hammer up and down. You see these connecting rods and wheels, and this structure is called the crankshaft, which can convert the linear reciprocating motion and the rotating motion of the wheel. ......"

Gao Wen patiently explained his thoughts. Heti listened and listened to it, and Rebecca's eyes sparkled: she had a keen interest in these designs!

The concept of mechanical devices that rely on magic to drive is not new. The world of extraordinary power has natural advantages in many aspects. Naturally, there are many things that appear to be "super-era" in Gao Wen, such as those made by magicians. The magical couple, the automatic gate activated by the key in the mountain treasure house, and the magic lock that was seen in the king and can identify the user's identity, these are considered the application of the magic organs, many of which can even be used. Black technology" to describe.

But Rebecca instinctively felt that the "magic power mechanism" proposed by Gao Wen and those things were not a thing at all.

Most of its structure is an intuitive and direct mechanical structure that does not require magical involvement.

Its function and purpose are extraordinarily simple, in order to provide power, and this power is prepared for the next level of machinery.

It is normative, standard, plain, and discards all the parts that let the craftsman "freely play". Instead, it is a numerical indicator that is as precise as the magic rules, and strives to achieve its purpose in the most reasonable and simple way, unlike those traditional. The rune craftsmen or wizards will play a lot of patterns on the magic items they have created, and they will have to work hard to hide those really useful runes in the complicated encryption lines, for fear of being seen. Come and understand.

Rebecca thought for a long time, and his mind often said one word to himself: versatility.

Just like Magic Net One, this device is also "universal".

It is not designed as a treasure or artwork, but like the Rebecca crystals fired in the kiln area, it is full of volume and reliable.

Gao Wen explained his thoughts and finally pointed to the cylinder structure that had been forked: "Now it is a bad step: it needs an initial power source, so that this 'piston' can move, I thought about letting The expanded gas is used to complete the process, so the sealed 'cylinder' is designed, but you don't have to be limited by my thoughts. From a magical point of view, which spells do you think can produce an uninterrupted energy supply as long as there is energy supply? Revolving propulsion power?"

Rebecca grabbed the chair and shook her body: "Is there a tiny hurricane in the inside? Make a haircut?"

Heti also frowned and seriously thought: "Not realistic, the hurricane law is too complicated, and the airflow it can illuminate in a confined environment is limited..."

As she spoke, she gathered a semi-transparent plastic hand by her side, but then dispersed the magic: "It would be simple to push it with plastic hand, but it is a special one. Spells, there is no corresponding magic array, and... It’s weird to have a plastic hand push in the machine to push it."

"The hand of plastic energy..." Rebecca turned his eyes and thought about it. Suddenly it seemed to open up a little thought. "Yeah, you don't have to use airflow...you don't even have to use this thing called 'cylinder'?"

Looking at Rebecca's brighter and brighter eyes, Gao Wenxin couldn't help but be happy: the stupid scorpion has to make meritorious deeds! ?

Hetty is also curious: "What do you think of?"

Rebecca was happy to draw a stroke: "Aunt, you remember that I had a spell that I never learned..."

Hetty: "In addition to fireball, which spell did you learn?"

"No, at that juggling level, you felt that even if my mind was stupid, I would definitely learn." Rebecca put his hand in his hand. "I later secretly painted the runes in my gloves and pretended that I would cast spells. The result was you." Hang up with Dad..."

Gao Wen: "..."

Does the girl say that it is necessary to be happy like this? !

And Hetty apparently remembered what the "trick" that Rebecca refers to: "Repulsive tricks?" 8)
