Wizard: Grinding Proficiency by Skinning

I transmigrated into the illegitimate son of a down-and-out noble, and from the start, a wolf bite leaves me with barely a breath in my body.

With no connections or resources, I have one stroke of luck: I'm bound to the God of a Thousand Arts System. Hunter, doctor, leatherworker... Whatever I learn, I can raise its proficiency and level up.

I keep my head down and stay out of trouble. First, I use my skill at skinning to establish myself in a small town. Then I improve potions, learn leatherworking, and take a position as a lord's adviser.

Starting out as a little hunter in Waguantown, I gradually delve into runes and magic, climbing the path of reshaping flesh and bone.

My goal isn't ambitious: first, I'll survive long enough to become a great wizard who can regenerate severed limbs.
