In this world, the word car still describes the kind of horse-drawn cart and ox cart pulled by livestock, and the four-wheeled machine made by Grandia, which looks like a machine without any external power, is the appearance of a modern car in Lawson's world.

In Grandia's own words, it was an iron box with four wheels.

"Oh, this thing looks weird, it looks a bit like a carriage?"

Veren asked curiously, he was indeed in awe and humble about things he had never seen, not at all like a sage who was alone in the world in the field of magic, but more like a studious and humble student.

"This is a magic locomotive. ”

Grantia said that this is the name given by Rosen, after all, this world has the convenient ability of magic, and cars do not need to start with steam power, and the so-called "car" naturally sounds weird.

"So, is it a means of transportation?"

Velen quickly understood what the name meant.

"That's right, the biggest difference between this magic locomotive and the traditional horse-drawn carriage is the energy, this locomotive is powered by magic. ”

As Grantia spoke, the door of the magic locomotive slowly opened, and she motioned for Veron to get into the car, and then took the driver's seat herself, and continued.

"Of course, this does not mean that this is a locomotive that runs entirely on magic, in fact, the magic is in it, and it is a trigger that activates. ”

She followed the instructions given by Rosen and lit the engine.

Only a roar was heard, and the entire magic locomotive trembled.

And Grandia, at the same time, projected a model of the engine in front of the window.

"This drive, which I call the engine, can take the explosive impact of ignition from a mixture of magic and air, convert it into the rotation of gears, and finally transmit it to the wheels to propel the vehicle forward. ”

In mid-air, the model of a four-stroke car engine is running at full capacity, and for Grandia, it seems a bit of a surreal scene, while Velen is staring intently at the engine full of modern design aesthetics.

"Compared to using magic to drive objects all the way, this engine can achieve extremely high efficiency with a small amount of magic power, especially explosions that can only be used for destruction on a daily basis, and it is quite a novel idea to transform them into the power of order. ”

After a little thought, Wei Lun roughly understood the core idea of this thing.

It's not so much that the magic locomotive is an innovative invention, but that this thing called the engine is the real innovation.

Moreover, through the application of the engine, many other things can be used at a low cost.

"Interesting. ”

Veron nodded, acknowledging the value of Grantia's invention.

"Then, I'll have to come up with the corresponding works to compete with it. ”

There is no doubt that the industrial base contained in the magic guide locomotive is completely beyond this era, even if Grandia can master the various design principles in it, but the lack of assembly lines and the manufacture of various materials can not make the magic guide locomotive quickly become something that the general public can enjoy, all thanks to this fantasy embodiment of the law field, the magic guide locomotive can be realized so easily.

From here, it can also be seen that the power of the Sage, although Lawson can create various items in his own law domain, it is at most based on reality, and only he can do this, like Wei Lun, the ability to pull others into his own law domain and give the other party the same permission, far beyond the scope of law application that Lawson has been exposed to in the past.

Of course, this also inspired Lawson, and what he saw and heard in the Sage's realm of the law also helped him to understand the law one step closer.

Veren stepped down from the magic guide locomotive and raised his hand slightly, and an almost identical engine model appeared in mid-air, indicating that he had completely mastered the structure of this machine.

Then, Veron smiled, and countless bolts of steel appeared from the void.

The hard steel, as soft as a flowing liquid, was twisted by Vinylon's willful thoughts, layer after layer on the engine that had just taken shape.

Countless circles shone brightly, like stars spinning, and flowed into the machinery that was being constructed.

[Ashes without fire: Hmm, this thing is...... Hey, hey, hey, that's a big deal. 】

Through Grantia's vision, Rosen saw the embryonic machine and let out a subtle exclamation.

[Ultramarine Fortress Scholar: What's that?]

Grantia was equally stunned.

This is because the appearance of the machine is somewhat similar to that of the magic locomotive, but it is flatter overall, and the wheels are not four.

On the left and right sides of the body, five wheels each, are being assembled next to each other, and above the wheels, a long metal strap is also covered with a tight loop around the five wheels.

Above the flat body, there is a square iron box, and on one side, a thick iron pipe sticks out.

The light faded, all the parts were in place, and eventually, a rather imposing machine appeared in front of their eyes.

Five pairs of load-bearing wheels, steel tracks, an armored body, and a straight barrel.

It was the prototype of the tank.

"If the previous one was a magic locomotive, then now this can be regarded as a magic locomotive, I added heavy armor and a cannon on the basis of the magic locomotive, and at the same time, in order to adapt to the requirements of complex terrain, while increasing the wheels, this belt was added, as long as there is this, then this car can drive on most uneven ground. ”

If Veron's ability to deduce the production method of the magic guide from a shining crystal is an extraordinary magical talent, then now, from the magic guide locomotive and the model of the engine, he can make a primitive tank, which really makes Rosen wonder if this guy is a time-traveler from a certain world.

Seeing Grantia's speechless expression, Veron only casually demonstrated some of the functions of the magic chariot and waved his hand lightly, making it disappear.

"Looks like it's my turn again?"

Grandia sighed in her heart that she was worthy of being a sage in the field of magic, even the invention of the magic guide locomotive that was ahead of the times was easily cracked by the other party, and in the face of Veron's question, she could only nod without confidence.

"Well, I think that's probably a good idea. ”

Velen raised his hand, and in mid-air, countless magic circles intertwined, finally condensing into the appearance of an item that Grandia had never seen before.

But for Rosen, it was nothing new.
