Another Stupid Isekai

I made breakfast for my surprise family. They didn't expect me in the house to make food for them but accepted this with happiness.

When they left to hunt, I immediately went to my workshop to dump all the materials I kept in my vault, then began working.

I had the project in the notebook, but I actually couldn't start with the skeleton. I needed to start with the core. It was quite complicated to make a material holder for the proper infusions. There were several ways how to do it utilizing different types of materials.

Since as my first creation I didn't want something too time-consuming but gathering very specialized and good enough for its function. And that function was, to exterminate a certain type of enemy of my choosing. I decided to go with the fire elementals because it was actually easier for me to design something immune to high temperatures with a toolkit to kill that specific type of monster using the opposite elements.

My water and ice magic was terrible, but In the case of infusions it was more of making a machine that would make certain effects than relying on my own magic, so I could actually go beyond of what I personally could do in terms of spells.

So the basic function of the core was as an energy source. Then it was also like a computer, controlling the rest. The brain of the machine. The energy, though, was more important, and this reacquired me to rely on the effect of overcharging mana. To do that I had to first calculate how much energy the whole project would need to function because if there wouldn't a way for all the power to leave the machine somehow while it would be generating additional energy, it would eventually explode.

This forced me to first think of all the functions of my golem, before even attempting to do the basic part.

"It had to be heat resistant, which means it would probably have to rely on barriers, plus a sturdy construction with resistant materials. I can enchant stuff so I could potentially make it out of anything and have the properties I want...", I thought to myself glaring at my own sketches in the notebook.

"I could make two generators of barriers in the hands, and add special crystals there to serve as batteries. Then add an additional one in the torso for an emergency shielding mechanism. I would have to have an additional two in the arms for offensive spells. Two in legs for dodging purposes, and one more in the torso for all the special needs. Then I should also make a venting system in case all the crystals will be filled with mana.", I kept thinking.

I write down some bullet points on the paper, to not forget about anything, then began counting more or less how much mana I would need the core to produce. It took me over an hour to do just that.

"What else?", I asked myself when I finished. "A way to store the crystals, which would need some kind of pocket dimension like my vault in The Void. I could do something like that."

I added the additional energy, to the calculation, and then began focusing on the core.

I needed an object as big as my fist, more or less. That was due to some of the basic principles of magic and infusions. To put it simply, the bigger the object, the more energy could flow through it safely, and the more energy overcharging meant bigger outcomes of the additional power. The size of the object had something to do with the heat being generated in the process of overcharging because some of the mana would slip out and it would turn into the heat naturally.

So to not melt your generator, you needed to get sufficiently big. According to my calculation and the knowledge I possessed, I could make quite easily infusion intricate enough to fit in such an object, and the excess energy wouldn't make it melt.

It could be smaller if I were to put more time into that, but I didn't want to.

So a ball of metal around my fist size, and then, on top of it a special shell with circuits made of some gemstones, filling specially drilled holes, to direct the energy to the right places. The precious gems were the best in terms of the mana flow, but due to the fact of them being rather stiff, I could only use them in parts that weren't really moving, so the core was perfect.

The shell would also hold the protocols, and basically control everything.

So yeah. That was my project of the core. I made it quite quickly using an alloy of aluminum because it wouldn't rust. For the circuits, I used small rods of solid ruby. Why? Because I like the color. Basically, it took me twenty minutes to make the physical pieces. The infusions, though, took four hours.

I made them work on only a tiny bit of mana necessary for the spell to stay stable, otherwise, it would either collapse because of the lack of juice or start generating power which wouldn't go anywhere, because I didn't have any other parts of the golem. Yet!

I checked everything twice to make sure it was performing well. Since there didn't seem to be any issues I could start to focus on the skeleton itself.

It needed a little bit of an update because I needed some space to put the crystals storing the mana inside the skeleton, so they would be protected properly.

It took me around additional half an hour. Then I finally started working on the proper parts. I still tucked to the aluminum, and that was mainly because of rust. Since the skeleton was supposed to stay there when the whole time, with eventual changes in the parts placed on top of it, I needed it to be corrosion-resistant.
