Regressed Genius Creates Mythic Items

On the day Earth is destroyed, a level-one alchemist with impaired mana creates the Philosopher’s Stone, a tool that can make anything possible in exchange for an equivalent price. He wants to strike back at the force behind Earth’s destruction and the person who murdered his younger sibling, and to escape life as a mana-impaired nobody. Believing his regret-filled life has ended, he opens his eyes to find himself eleven years in the past. Determined to change his future, he sets out to rewrite his pitiful life as an outcast and prevent the miserable events he knows are still to come.
