The Annihilation Furnace is one of the Treasures of the Heavenly Medicine Sect.
However, this kind of furnace cannot be used for Refining Medicine, it is said that the sect chanced upon it thousands of years ago.
Inside the furnace rages a heaven-defying flame, so domineering that even cultivators at the middle stage of the Golden Core would end up being burned alive.
Of course, the Annihilation Furnace isn't simply capable of incinerating cultivators; if someone with a Lifebound Flame is burned inside, throughout the process of their physical dissolution, the energy will gather within their Lifebound Flame.
In the end, their Lifebound Flame, after being consumed by the flames within the furnace, will become ownerless, and at that moment, the person controlling the Annihilation Furnace will be able to take the Lifebound Flame for themselves.
