Reincarnating as a demon in sousou no frieren

By using "Interne Anzeige," I was able to clearly see how my body works on the inside. I realized that if I disperse the waves, I can visualize the general shape of organs and tissues, but if I focus them, I can see details at a micron level. With this, I have created a detailed record of my entire body, and what I discovered is astonishing. My muscles are much denser than those of humans, and they seem to be naturally reinforced by magic, which enhances my physical strength. Furthermore, I have noticed that everything I consume is transformed into mana, which led me to conclude that my body does not run on biological energy but rather relies on mana. This could be a characteristic of beings with mana in this world. Now, with a more accurate view of how my body is composed, I will try to make it work as efficiently as possible, optimizing the use of mana instead of relying on the traditional biological process. This could lead to a substantial improvement in my physical and magical abilities. Now that I have a deeper understanding of how my body works, especially my brain, I know I can apply that knowledge to improve my magic. Apparently, understanding internal processes is key to optimizing mana usage and making my magic work in a more efficient manner. While I know creating improvements and optimizations will take time, I have a clear direction to follow. For now, though, I need to go out and explore. The forest seems like a good place to find beings similar to me or perhaps some monsters, like in isekai. But before that, I can create a spear for myself, something I can use to defend myself or hunt if necessary. With a little work and concentration, I can forge something useful.
