A Pill Furnace.
It is a medium, an indispensable tool for an Alchemy Master.
Beyond maximizing the success rate of concocted Elixirs, its most important function is to control the heat!
If the Pill Fire's power is too great,
not only will it be impossible to refine the essence from the medicinal herbs, but they might even be burned directly to ash.
Therefore,
many Alchemy Masters use a Pill Furnace to slowly raise the temperature of their flames.
But Chen Han didn't need to.
Because... this Spirit Core came from a Demon of the Nine Netherworlds.
These Demons grow amidst endless flames, and their Spirit Cores naturally contain an infinite amount of fire.
"HISSS!"
A drop of sweat had barely formed on Chen Han's forehead before it was evaporated by the scorching heat, turning into a wisp of steam.
'Damn it!'
Chen Han couldn't help but curse inwardly.
