After dealing with his rather useless twat of an elder brother and celebrating his daughter's birthday appropriately, Bruno would finally open the letter sent to him by Emperor Meiji. It was as he suspected—a letter of invitation to visit the land of the Rising Sun to witness the prototype machine gun they had developed as per the recommendations he had made in passing.
Even if the machine gun turned out to be relatively crude, the mere idea that it would be using an air-cooled quick-change barrel, along with a built-in bipod, stock, and pistol group, meant it was leagues ahead of what was currently being fielded by all nations other than the Reich.
Because of this, Bruno was quite interested, as if his recommendations were followed to the letter. Then it was entirely possible that a new machine gun had been developed, one that only existed because of his interference in the timeline.
