Blacksmith Life BSBT

Ryan, a multi-quadrillionaire and super genius accidentally destroyed the solar system whilst trying to create a rechargeable atomic carpet bomb more powerful then single use ones.

Anyway he’s blasted into another reality, one where beast taming is a thing but all he can do is be a blacksmith, luckily he specialised in weapons in his previous life since there is where the money’s at.

He would create a weapon creating empire, all with no system whatsoever.
