Reborn as an Evolving Lich with a Beast Taming Farm

A down-on-his-luck man dies, is reborn as a low-tier lich in a forgotten cabin… and discovers a magical Beast-Taming Farm in the backyard that levels up both its creatures and its master because every monster he raises changes him in body, mind, and power. ══════ Note: MC will stay a lich throughout, none of that human nonsense.
