Karl Wagner is a disgruntled middle-aged instructor at the Bundeswehr Command and Staff College. He finds himself concerned about the direction which the German nation is headed in—just as he is killed by a terrorist attack. Only to awaken and find himself reborn as an infant, Bruno von Zehntner, the youngest son of a noble family renowned for its part in the German war industry a few years after the founding of the German Empire. Bruno, as he is now known, desires to rewrite history and ensure the German Empire emerges victorious in the coming century. And in doing so, finds himself entrenched in a world filled with Blood and Iron!
Things were progressing much as Bruno had predicted on the global stage. The year was currently 1911, and soon enough the advanced Type XXI U-Boats Bruno had prepared years in advance would begin production, hopefully replacing the current U-Boat Types, which were woefully obsolete when compared to the variant he had introduced to the world decades in advance.
And while his armored vehicles, planes, and warships were all either already in production, or were getting close to it, there was one other invention Bruno had not introduced until now. It was, frankly speaking, an oversight on his part not to do so earlier, but at the same time, he still had enough time left before the war began that it didn't matter all that much.
Currently, Bruno was at home, with a beer stein in one hand and a sandwich in the other, looking over the details of the rough draft he had just concluded. It was a rather small device, at least compared to the weapons he had already designed.
