Spring Water from the Forest of Echoes

Deep inside the Forest of Echoes in Solo Leveling, a place also called the Forest of Trials, lies a hot spring, and the water drawn from it is a consumable item in its own right. Its value runs in two directions. Drunk or applied to the body, the water neutralizes toxins, and it does so at a potency far past anything a hunter would carry as a standard antidote. It is also one of the ingredients required to brew the Holy Water of Life, which is where most of its reputation comes from, since that recipe cannot be completed without it. Sung Jinwoo obtains a quantity of the water on the seventy-fifth floor of the Demon Castle, well before he has any use for it.
