I recommend "Building Mechs in a Primitive Society" to you. The male protagonist of this novel transmigrated to the orc world and had the talent to build mechs. He gradually grew up in the other world. He was a protagonist who could take responsibility, but he was not a small subject. This novel has some technological elements, but also the primitive wildness of the orc world. It will make you feel addicted. I hope you like this recommendation. Muah ~
