Over four thousand years, he had single-handedly carved out an exclusive branch of "Dark Cave Magic Potions Study," creating over a hundred different dark cave magic potions!

Among them was an "age-reversing" potion made primarily with 'Rejuvenation Flower' as the main ingredient.

The Rejuvenation Flower is a type of plant that, when ingested, initiates a "rejuvenation" process, causing one to devolve in growth, regressing from adult to infant, then to an embryo, and finally turning to ash and disappearing, making it a deadly poison for living beings.
