Gao Yang was excited for a reason, as he had seen a gun in the photo.
The most valuable piece among the antique shotguns Gao Yang gave to Morgan was made by Clemens, a double-barreled shotgun once used by Emperor Franz Joseph I of the Austro-Hungarian Empire.
Both culturally and as a shotgun itself, the shotgun Gao Yang gave to Morgan was an incredible antique, but for Morgan, the most important gun was the one that Emperor Franz Joseph I had given to his queen.
It was the shotgun once used by Morgan's mother, and then by Morgan's father, and by Morgan himself, who had both spent their lifetimes searching for it but could never find it.
