There was also plenty of s.p.a.ce for resource materials like metal, wood, gla.s.s and other materials as well. On one side of the warehouse was one door that was thirty centimeters thick that could not be opened without the use of wind magic that connected to a tunnel that led to our house. This tunnel had four other doors that were the same that lined the tunnel as safety measures in case any demonic beast infiltrated our tunnel.

There were also many pulley lever systems setup that used weights to control traps doors placed along the floor for security. I know these kinds of systems are old but for now, it was the best we could do. Until we have the materials to use magic inscriptions we were stuck using very old technology. These trap systems actually took the longest to get working since they required so much attention to detail. These were systems that were used in ancient times on earth and to be honest, could be considered technology that was advanced for its time.

After all this work Rio and I were actually really proud of ourselves. In such a short amount of time, we had come very far. But today was the day we were going to test the new and improved sled. The new sled function much like a car minus the engine. I set up a wheel and axle system that connected to a steering wheel. The only downside at the moment was that the current propulsion system was human. In other words me. Rio would steer while I would use magic to propel the sled.

There was a four thruster system set up. Two thrusters in the back to propel the sled while there were two in the front to slow the sled to a stop. Of course, depending on the current speed of the sled told us the amount of power needed to slow and stop the sled. In a way, I was really proud of myself for being so inventive. Eventually, I want to make the whole system automated and have no need for anyone to actually control the sled. I guess you could say it would end up being more of a magic golem by then.

"Okay, Rio are you ready?" I asked as I was getting ready to activate the sled.

"Un!" Rio turned back to me with a smile.

"Okay then. I will start off slow then when you think you got the hang of it, I will speed up." I was about to start everything up when I felt a hand on my shoulder. Then a face in front of mine as my lips were being stolen.

"That was four good luck! Ready when you are!" Rio said with a bright smile.

I shook my head and smiled back as I started up my combination of wind and fire magic. After exerting a bit of power the thrusters burned as the sled slowly moved forward! I was teeming with excitement at this time! The sled was actually being propelled forward!

Before I could say anything I heard Rio shouting out: "We did it! Speed up slowly and I will tell you when to stop."

Doing as she said I slowly poured more power into the thrusters causing the sled to pick up speed. It was not the most comfortable ride but at least I made sure the tunnel floors were nice and smooth and straight. Before I knew it, we had already gone halfway to the ruins in one go! It had only taken an hour! Not wanting to stop I continued pus.h.i.+ng our speed faster and within thirty minutes more we had already arrived at the ruins! I had to quickly slow the sled down because we were going around 110 kilometers an hour! Just to slow us down caused me to use quite a bit of magic power but we did come to a full stop a few meters away from the entrance to the building.

"Sora a three day trip in such a short amount of time! Your idea was genius!" Rio happily wrapped her arms around my neck as she jumped up and down.

"Un! But I think we should go a lot slower even if we turn it into a four-hour trip it would be safer. At least until I am able to make these automated. But with the two of us on board at this time it would have been dangerous if the braking system did not work how I thought it would. Luckily it did work but it consumed a great deal of magic power." I had to say, I was very tired right now. The breaking took a lot out of me.

"Un, we will go slower so no one gets hurt. Come let's go into the shelter I will take care of recharging your magic supply." Although she said to go into the shelter she was already stripping me of my clothing before we even started walking. Not that I cared I mean Rio and I have had s.e.x basically on every centimeter of this tunnel. As soon as I looked even the slightest bit tired she would hurriedly remove my clothes and start working my p.u.s.s.y. You could say our moans of pleasure would echo throughout the tunnel nonstop some days.
