In the novel, the protagonist established a base abroad and produced aircraft and aircraft carriers. This base was built overnight using alien technology.

I recommend "Doomsday Mecha Black Technology Base" to you. The protagonist of this novel established a base in the wasteland and created high-tech products such as airplanes, aircraft carriers, and mecha through the development of alien technology. The base was built overnight, which greatly improved the protagonist's abilities. I hope you like my recommendation. Muah ~
