Everything was ready soon, and Su Wen began operating in the Alchemy Room he had set up at home.
The necessary herbs had already been counted and placed at hand by Su Wen, and in front of him was an old-fashioned ceramic pressure cooker that Liu Die had found on some app.
The fire had been burning for two minutes, and after sufficiently preheating the pressure cooker, Su Wen started adding the herbs into the pot in order according to the legacy in his mind.
After blazing for an hour, Su Wen slowly waited for the pressure cooker to cool down before opening the lid.
"It failed…"
The herbs in the pot had been cooked into two layers under high temperature and pressure.
The bottom layer was dry wooden dregs, and the top was a layer of black, paste-like substance.
This paste was the essence Su Wen was after, but just by opening the lid and smelling it, he knew the composition was off.
Having the legacy in mind was one thing, but actual operation was another.
