A drop of blood accidentally activates an ancient furnace during a blacksmithing livestream, binding the streamer to a mysterious black blade that fights on its own.
Every item forged from customer-supplied materials turns out to be an absurdly antisocial piece of gear, and the livestream's popularity skyrockets.
The furnace has a strict upgrade deadline, and missing out on an ore vein of the same origin will severely weaken its forging abilities.
The abandoned mining district is full of danger, and a mysterious conglomerate is secretly coveting the black stone. I can only keep the livestream entertaining while venturing deeper to uncover the stone's secrets.
