Condensing liquid into pill, the most crucial step in the alchemy process.
At the same time, it's also the most difficult step.
This step requires the alchemist to grasp the timing and intensity of the fire with extreme precision.
After refining the pill liquid with high-temperature flames, quickly lowering the temperature in the pill furnace to a certain point in a short time.
This is extremely difficult for ordinary alchemists.
But for Lin Chen, who uses instruments for alchemy, it's not so complicated.
"Pill solidifying stage... the temperature in the furnace needs to drop by about three thousand degrees."
Lin Chen murmured to himself, he could only roughly judge the temperature range, the exact temperature still needed to be tried.
So, unsurprisingly, the first attempt failed.
The entire furnace of Foundation Establishment Pills was ruined.
Later, Lin Chen began his second and third attempts.
He failed a total of six times.
