Since Pochi and the others are satisfied, I decide to open the path with magic from the afternoon.
First, I fire [Air Blade] that follows close to the surface of the ground along the road.
The wind released from the short wand cuts the weeds while leaving 10 centimeters of it above the ground. The wind continues on while cutting some slightly elevated grounds, and bushes along the way. In the end, it finally stops 200 meters ahead on a small five meters tall cliff.
"You, you really should learn to stop overdoing it."
"Nn, destruction of nature."
Was it too shocking, Arisa grumbled with more unreserved tone than usual. Is it because you're scolding me that Liza is taking regretful pose.
The fact that the trees along the road are cut is within my expectation, but for even the cliff to be cut in two and crumbles is beyond my expectation.
If we advance just like this, the horses can sprain their legs from the unseen ramp, and soft grounds, so I decide to prepare the soil with earth magic.
This time I'm not using [Wall], but the very thing itself, that is [Flat Land] magic. Seems it's a magic that's used frequently by not only the army, but also the general populace. It was a magic from the scroll that I had bought from the firs magic shop I visited in the duchy capital, but I didn't have opportunity to use it until now.
I set the range to be the course of the road and exercise the magic. Since the ground is covered by weeds, I don't know if the soil really has been prepared, so I check the terrain on the map. Looks like it's been leveled without problem.
Since the cut weeds are hindering the horses feet, the wagon isn't speeding up. The wheels are also looking like they'll slide. I instruct the wagon to running slowly at only several kilometers per hours speed, we're going while opening the path anyway.
I'm leading while using magic, and Pochi and Tama who are walking while picking up herbs and medicinal plants from the cut weeds. Liza and Nana are removing bushes and fallen trees that are out of bounds from the road. Arisa and Mia are sorting the gathered materials.
However, it'll inevitably take some time. Naturally, the road to the mountain range is not just extending straight, and not flat as there are undulations too. Particularly, the road goes around hills, low-laying mountains, and valleys.
Since I don't have any other good plan, we're advancing on while opening the highway, and I decide to camp on the bank of the streamlet 10 kilometers ahead.
Although there are around 20 demi-goblins 1 kilometers away from the planned camping ground, they seem to have become frightened by the sound of vegetations cutting and ran away very fast. It's going to be safe tonight.
I left the dinner preparation to Lulu and went back to the place where I started to clear the path, I put a rough 100 meters wide mud wall [Wall] there. With this, there won't be strange rumor about the road that suddenly appears.

That night, I've assembled an aerodynamic engine that's been half completed.
However, the control is difficult.
After it was finished, it did float when I tried to put mana into it little by little, but it was bad after that.
After the engine fed on a certain amount of mana, it rotates down to the ground with a plop, and then it powerfully plunges to the nearby tree.
Apparently, the fins that are composed on the aerodynamic engine each has its own fixed output on top of having the so-called power band. Due to that, you can't just pour mana into like normal magic tools as it will rotate off-balance and accelerate suddenly.
Looks like it needs a control circuit for tuning the output, but there's nothing about that in the documents I have at hand. There isn't also anything about how the control of aerodynamic engine is difficult written in the documents, don't tell me that the author of this document actually hasn't assembled the engine himself.
"Or maybe the control itself isn't something that's impossible to do?"
Although the frame of the engine that has hit the trees and the shrubs are broken, the fins and the magic circuit themselves are fine, so I'm going to challenge it again. I can more or less make the aerodynamic engine floats for about 30 seconds, but since I have to concentrate on it all the time, it's too bothersome. If it's like this, even lifting the wagon with [Magic Hand] is better.
I'm searching for any other hints until late at night.
