The plan to make the original cement of the head iron fireball baby failed, but Gawain was not going to give up so easily - the experience from the earth may not work, but the idea from the earth is not necessarily wrong, maybe the formula of some things is different, but this does not mean that this kind of thing has no value, at the very least, a cheap and strong and easy to process building material should be useful wherever it goes.

Even if it were to change its name to Magic XX in this world.

He sent Rebecca to try new manufacturing processes, and told them the general idea and his intended goals, and this was not a random attempt without direction: although his own production method failed, Gawain knew that the world once had "cement".

He and his men had seen the material deep in the mountain ruins, and the engineers of the ancient Gondor Empire had built the fortress deep in the mountains with man-made materials instead of stone, making the fortress stronger than the average stone fortress, and there was no sign of collapse after a thousand years.

As far back as Gawain Cecil can remember, the material was developed in the "Iron Age" before the "Spark Age" and was used for ten centuries, refining and perfecting it until it was one of the most widely used building materials in the empire by the end of the Gondor period.

And this is what Gawain regrets the most: after the collapse of the Gondor Empire, a large number of technologies have been lost from generation to generation, some because the technology itself needs to rely on the Deep Blue Mana Well, some because the group that has mastered the relevant technology has been extinct as a whole and has left no information, and some because the raw materials (or environment) required for the technology have been covered by polluted areas, and the "otherworldly version of cement" of the Gondor Empire is one of the many lost technologies.

Due to the chaos of that era, Gawain was not sure which of the three points caused the loss of this technology, but it was not because of the magic well: the production of the otherworldly version of cement was the same as the earth's cement, and it did not require too complex equipment and too advanced energy, so it was most likely due to the extinction of talents, the loss of data, or the problem of raw materials. Anyway, this technology, which should be the most basic and one of the cornerstones of civilization, is gone.

Seven hundred years later, the Ansu people built houses out of stone and wood, and those nobles who could afford it would extravagantly use magicians' various shaping spells and alchemical potions to make their palaces and castles more refined and strong, but the latter obviously did not meet Gawain's requirements of "generalization, cheapness, and mass production".

But although the technology is broken, it is not without help, after all, it was one of the most common basic technologies in the Gondor Empire back then, Gawain Cecil had seen it even if he hadn't done it himself, and now there are still a few fragments of related technologies left in his mind, give these fragments to Rebecca, as for how far the technology can be restored...... Then it depends on the ability of the iron-headed fireball baby.

At this time, Gawain couldn't help but sigh: if Gawain Cecil was a keyboard powerhouse seven hundred years ago...... A little bit of the force value to all kinds of miscellaneous learning, the current situation is much better, not to mention anything else, at least remember the cement formula!

In the spirit of "who can be afraid of the satellites that have become refined for hundreds of thousands of years", Gao Wen unscrupulously recited the original owner of his body, and then began to make a list of the various experiments he had to carry out next.

Then, over the next few days, Amber saw Gawain send a large number of things to the tent, strange ore powder, metal containers spliced together, large and small crystal lenses, and magnets and wires commonly used by magicians and soothsayers, all piled up on a table, half of which were urgently purchased from Tanzania, and the rest were processed by Gawain under the direction of Heti and the craftsmen.

Looking at the table of things, Miss Half-Elf was confused: "What are you doing here?" ”

Gawain replied without raising his head while fiddling with the lens group in front of him, "Experiment." ”

"The nobility is so hard to understand," Amber blinked, and then her eyes lit up as if she had finally caught Gawain's little tail, "Oooh! I've finally found out! You guy really can't pretend to be a plaything! I'll just say, how could a nobleman with a normal brain endure suffering for so long, and you finally started to work hard and lose money...... Alas, it hurts, it hurts!! ”

Gawain twisted Amber's ears twice and then let go, looking at this guy with a daily lack of sex very curiously: "I can't figure it out, do you not remember the fight or what, can't you make your temperament a little cute?" ”

"You nonsense! I'm a big thief who was tied here by you as a bodyguard, usually either guarding your large pile of ghost talismans or helping you patrol and collect intelligence all over the mountains, and occasionally you let me learn to study ghost talismans with you for a long time, do you respect my profession! ”

Miss Half-Elf said that the central idea can be summed up in nothing more than three words: I am idle.

"You're not as motivated as Betty," Gawain covered her forehead helplessly, "She still comes to me to learn literacy after she is busy every day, and it's so difficult for you to learn addition, subtraction, multiplication and division?" ”

"Oh? It turns out that the little maid is really learning to write? Amber blinked, full of interest, "No wonder some people in the past two days say that when they see her alone, they will talk about it, and as long as they have time, they will hold a branch and write and draw on the ground......"

"Okay, okay, I don't care about you anyway, if you're really idle, go out and play by yourself," Gawain waved his hand at Amber, "Anyway, three things are not allowed: no stealing, no trouble where you are working, no fighting with people - of course you can fight with geese." ”

Amber got Gawain's permission and immediately happily rolled back into the shadows, while her body faded and muttered, "You are really weird, why do you always emphasize goose ...... in front of me"

After Amber left, Gawain finally had a chance to focus on the large pile of things.

Some of them he has already tested, and others are being verified.

Before sitting back in his chair, he glanced at the large basket next to him, and then sighed slightly.

The big basket contained the indescribable aggregates that Rebecca had created when she had fired the cement before, and Rebecca had intended to dump them, but Gawain had left them behind, and had placed them in a place where she could see them at any time.

He sees them as a kind of wake-up call, a sign, a sign that reminds himself that "this world" is "this world".

Retracting his gaze from those things, he glanced at a container on the table, lowered his head and wrote a new record in Chinese on the paper:

"In the year 735 of the Ansu calendar, on the 46th day of the frost month, the 23rd day of the camp development, the gunpowder manufacturing failed, according to the classic formula of the earth's experience and the various formulas of the magic modification version are ineffective, none of the finished products can produce rapid combustion, release a large amount of heat in a short period of time or similar effects, the finished product of the classic formula is non-combustible at all, and the finished product of the magic formula No. 1 formula can burn quietly in the air, but the flame is dim and weak, it is better to burn straw; The finished product of Formula 2 also burns quietly, but has a bright and steady flame, which was intended to be used for lighting, but it emits a pungent smell......

"If you continue to test, you may find a usable otherworldly version of the gunpowder recipe, but I am already vaguely aware that this route may not be the best choice, it is gradually distancing itself from the 'magic' of this world, and the power is not expected, and it is probably more reliable to study a burst rune that can be industrialized and mass-produced than gunpowder."

And there were many more records on the paper, and Gawain's gaze was sweeping over them:

"In Ansu 735, on the 45th day of the frost month, the 22nd day of the opening of the camp, it was determined that the electromagnetic induction was invalid, at least the process of 'magnetic generation of electricity' was invalid, and no current was generated in the coil. It has been determined that the magnet exists at the north and south poles, and its properties are the same as those of the earth's magnet, and the wind element rune provided by Hetty can also sense even the weakest electrical stimulus, and the coil is rough but meets the requirements, so the problem can only be the electromagnetic induction itself. It is still unclear if the process of 'electromagnetism' is also ineffective, as Hetty's lightning arrow magic is unable to provide a constant and steady safe current, and a thunderbolt in her palm nearly chops Amber's hair......

"It seems that the plan to use generators to charge the wind system array can only be put on hold for the time being, or if we have mastered the means of temperature difference power generation."

“…… Prepare to give up the steam engine, the results of the experiment are simply head-scratching: the process of boiling water in this world looks the same as on the earth, but the driving force generated by steam is pitifully small, perhaps the expansion coefficient of water in the process of transforming into water vapor is much smaller than that of the earth, I suspect that the 'water' here is not water at all, or it may be that the ubiquitous 'water element' in this world is playing tricks, this unreasonable thing changes the specific performance of water in the transformation of three states......

“…… Although I drink it, wash my hands and face with it, and it can also be used to water the ground and flowers, it doesn't prove anything: my body is already made up of the elements of this world, my senses are working according to the rules of this world, and there is no part of me that can jump out of the 'worldview' of this world to observe except for a consciousness from the earth in my head...... Is the blue sky I see really a 'blue' sky?

“…… In any case, the course had to be adjusted, and the proudest part of human civilization on Earth had been hit hard: I couldn't 'boil water' here, I lost my boiler, how could I get the most basic machines up? ”

"Ansu 735...... Hetty had never heard of "coal", neither had the druid named Pittman, and in fact there was nothing like it in Gawain Cecil's memory...... The good news is that charcoal can still be burned.

“…… Typhon's empire produced a 'burning stone', but instead of coal, it was a white 'burning stone', which seems to be a type of seawater sediment, which is more resistant to burning than wood, but it is not easy to ignite, and I have heard that the burning is very unstable, and the smell is not good, only the poor will use it for warmth, keep an eye out.

“…… Oh yes, gold turned out to be semiconductors, while sterling silver is non-conductive...... What the heck?!

"I think I need a whole cutting-edge team to give me the whole periodic table...... Or at least sort out the properties of all the common substances.

"However, no.

"Wash and sleep."
