Hearing Hetty's words, Gawain's expression immediately froze - ooze monster excrement?!

Over there, Rebecca was still nodding excitedly: "yes, yes, yes - we have a big pond in the backyard of the Magic Guiding Technology Research Institute!" One of the ooze monsters was caught by me......"

Gawain finally found out what happened to Hetty's previous report that Rebecca was raising ooze monsters......

"It's a shame you figured it out!" Hetty's expression was weird and weird, "I'm curious how you connected these two things......"

Gao Wen couldn't help but cover his forehead: "Why do I feel a little disgusting?" ”

"It's not disgusting," Rebecca said immediately, "although it is said to be the excrement of ooze monsters, but ooze monsters are more of an elemental creature, and what they excrete is more like a mixture of molten slag generated in alchemical reactions, clean - aunt, didn't you tell me that the mages of the Violet Kingdom would even use ooze excrement to apply ooze monster excrement to their faces to improve their skin?" ”

Hetty couldn't help but cover her face: "...... But that's an abusive word......"

Rebecca scratched her head: "Huh? Is that so? ”

Listening to Rebecca and Hetty's conversation, Gawain quickly accepted the source of the material for the "tire" in front of him.

He knew the ooze monster - a weak but powerful magical creature that usually lives near the focal point of mana, and is the product of a combination of earth and biomass. Wild ooze monsters are not aggressive in their own right, but because their habitat is close to the focus of mana, there are often strong monsters nearby, and it is not easy to catch them - but since they are not very useful, except for a few mages who seek out ooze monsters for specific materials, the average person will not be interested in those low-level elemental creatures.

Elemental oozemites leave behind a variety of gel products that are their "excrement" after eating dirt and decaying plants, but as Rebecca says, as long as they are psychologically adjusted, they are nothing more than a by-product of a magical reaction......

But anyway, I looked for inspiration in the ooze monster's excrement, and even thought of making tires out of it...... It's a fresh and refined way of thinking.

With a strange expression, Hetty continued to poke the gray-white slightly elastic "tire" with her finger, and asked curiously, "You should have dealt with it, right?" The normal ooze croaking secretion should be softer than that, and it smells stronger......"

"We mixed it with very fine quartz sand, and as for the smell, we used gum from Giantwood to remove it, and the effect is not bad, but I think there should be room for improvement," Rebecca said as she nodded, "In addition, we have tested a lot of different 'feeds' to make the secretions discharged by the ooze monsters more compliant, and this feeding formula is definitely not the most suitable ...... right now."

Ooze monsters are very strange elemental creatures, they eat everything, and then carry out complex magical reactions on the substances they swallow into them, and draw energy in the process, their physiological processes are like a continuous alchemical reaction, which leads to the fact that if they eat different things, then what they excrete will also be very different - of course, they are basically gel products of various viscosities and hardness.

Looking at the gray-white "tire", Gawain nodded slightly.

There is no natural rubber in this world, and humans will never be able to make artificial rubber based on the oil industry, but alternatives are still emerging.

Regardless of how Rebecca came up with this solution, the fact that a low-level primitive magical creature had solved a big problem in the wizarding industry was enough to make Gawain confident enough about the future.

"Can it move now?" Gawain asked expectantly, pointing to the prototype magic guide car on the mechanical platform.

"Of course~~" Rebecca said happily, "we had already started it once in the air before you came, and we tweaked a lot of minor issues, and now it's fully open." I haven't tried it, but I think it can even be driven outside the workshop. ”

Gawain didn't talk nonsense: "Demonstrate." ”

"Okay~~" Rebecca had been waiting for the old ancestor's words for a long time, and immediately walked towards the mechanical platform while agreeing - obviously, she couldn't wait to show everyone this miracle of the magic industry in person.

Gawain watched Rebecca get onto the platform, then climbed onto the pile of mechanical monsters made of steel, watched her sit in the rudimentary, directly welded to the frame, and then began to pull the levers and wrenches in front of the operator's seat, on the chassis of the prototype magic car, the runes gradually brightened, a low hum sounded from the connection between the power ridge and the magic engine, and countless gears and levers began to tremble slightly, brewing surging power-

Hetty listened to the movement coming from the pile of machines, and looked at Rebecca, who was excitedly fiddling with the lever, and couldn't help but worry on her face: "Ancestor, is this thing really okay?" ”

"You have to believe her," Gawain whispered, "and believe in the hard work of so many technicians for so long. ”

Hertie opened her mouth, as if she wanted to say something, but all her words were swallowed back after she saw the scene in front of her—

The heavy, black-steel, myriad-hull industrial beast let out a low roar, and the rotor engine set all the mechanical mechanisms in motion, its four wheels slowly turning with a vibration and rattle.

"Look, Ancestor! Let's go!! ”

Rebecca shouted happily as she pulled another lever on the left side of her body, and the wheels sped up with a series of gear clicks—and in a flurry of noise and vibration, the massive machine stepped off the platform like the first cry of a human baby, and the sound it made was noisy and loud.

The mechanical and wizard technicians around the platform cheered and clapped vigorously.

Gawain knew that the machining accuracy of the Nicholas Egg could be very high, but that was when the blueprint had been perfected, and when the prototype was built, in order to verify the blueprint and improve the success rate, in order to leave enough safety margins for all mechanical structures, in order to facilitate the mechanics to confirm the wear ratio of all structures and facilitate disassembly and transformation, these initial machines would leave an acceptable margin between the parts, which led to the noise and vibration of the prototype magic guide car during driving- They sounded noisy and chaotic, but the mechanics felt the sound familiar and familiar.

It means that a new mechanical creation has been born, and the sound of the collision and friction of gears and levers is a loud announcement of the birth of a new mechanical spirit in this world.

Rebecca drove the rudimentary prototype off the platform, and then controlled it to drive around the vast open space of the workshop, the girl who was supposed to be dressed in a splendid aristocratic dress and sitting on the terrace decorated with flowers and gold for tea and flowers, now wearing a dirty researcher's robe, sitting among a pile of iron frames and parts, screaming even louder than the machinery beneath her—

"Look, Ancestor! Look, Auntie! It's really walking! It can still run!! ”

She smiled like a child.

To Rebecca's cheerful laughter, the lever of the Magic Guide Car was pushed into a higher acceleration gear - as far as the workshop space could allow, the complex machine picked up speed once more, and it let out a loud roar, and the Magic Engine drove the gear set to the exit of the workshop: it was clear that Rebecca was going to drive the car outside.

There's a worried look on Herty's face, but Gawain gently taps her shoulder.

Hetty breathed a sigh of relief, and then put aside all the unnecessary worries: there was a legendary powerhouse watching here, and Rebecca and the "robot friends" she created should not be able to make a big mess no matter what.

However, just as she was breathing a sigh of relief, the machine car that had run to the door of the workshop suddenly sounded a strange creak, accompanied by a continuous noise like metal colliding, the car slowly stopped in a series of huge vibrations, and the magic runes on the power ridge were extinguished one by one.

Gawain and Herty glanced at each other, and then a large group of people hurried to the place where the locomotive was lying down.

Rebecca twrestled the lever next to her seat and pressed the pedal again, and when she found that she couldn't restart, she got up from her seat and jumped to the ground in frustration.

"It's broken."

She said to Gawain with a sad face.

However, just as Gawain tried to comfort the girl, Rebecca turned her head, pulled a wrench and a taper from her pocket, and began to dismantle the cover between the magic engine and the mechanical cabin.

A large group of technicians immediately gathered around, and Nicholas Egg floated above the locomotive and began to help Rebecca get the jammed or even twisted gears out of the gearbox and differential.

In the presence of Gawain and Hetty, the Mechanics and the Wizard Technician began to discuss:

"The shift seems to be stuck......"

"The differential seems to be fine...... It was damaged by inertia after the gearbox suddenly jammed. ”

"How can it be stuck...... Is it okay when you test it alone? ”

"Is it that the lubricating grease is less effective when it is rubbed and heated?"

"Definitely not, this kind of alchemy ointment is also used in the puppet, and the temperature of the puppet's power core is much higher than the friction of the gears......"

"Oh, look at this linkage - it looks like it's stuck! It fell off when it was shaken! There is a problem with the way the connection of this place is! ”

While Gawain was still hesitant to go in and see what was going on, the discussions among the technicians seemed to have come to fruition.

Rebecca came out of the pile, and the girl had several more grease stains on her face, but her eyes, which were still very depressed just now, had already shone again: "Ancestor, the problem has been clarified!" There is a problem with the connection of one of the connecting rods......"

"It was our mistake," a mechanic in blue overalls stepped forward, and Gawain recognized it as one of Hammer's apprentices, "We didn't estimate the impact of the tremors. ”

"It's okay, it's normal for the prototype to have problems." Gawain didn't blame anyone in the slightest, on the contrary, his happy mood at the moment was not at all diminished by this small mechanical failure.

Although there was a mechanical failure, it was just an inevitable episode in the development process - Rebecca drove the prototype magic car off the platform, and that was the real point of today's test.

This shows that, at least on the whole, the design of the magic guide car has been successful.

He looked up in the direction of the mechanical platform in the center of the workshop, then retracted his gaze to look at the prototype that was quietly parked at the door of the workshop.

From stepping off the mechanical platform, testing in the workshop, and then driving to the exit of the workshop, the first magic locomotive should have only traveled four or five hundred meters.

It's nice, it's four or five hundred meters.
