'It's time for the third step,' Ye Chen thought as he controlled the ice flame to purify the herb essences.
Even with the extraction process, some impurities remained, and he couldn't allow this as it would lower the quality of the pill.
This purifying step was something optional because it led to explosions a lot of times.
After all, purifying the herb essence meant burning the impurities with flame; if there was even a slight error, all the hard work from before would go to waste.
However, Ye Chen didn't care about this as he wanted the higher-quality pills, so he started to heat the essence at a certain temperature, burning impurities within herb essence.
This process was a lot slower and took him a half hour to purify every herb essence perfectly.
Just as he was doing this, Li Mei got bored because she wasn't able to see anything inside the cauldron.
