Black technology: I have a refitting factory

Originally there was still a lot to follow, but it was a bit sensitive and this volume may have to be passed quickly. There should be no more than three chapters today. I'll sort it out and can only post a rough outline of the plot...

Open directly to the next volume of defense.

It’s better to write about some black technology that is beyond the existing technology, otherwise it will always be reviewed and the book will be lost.
