The Nine Nether Spirit Devouring Thunder Flame blazed fiercely inside the crimson Pill Cauldron. Suddenly, Long Yan reached out, grabbed all the medicinal materials, and threw them into the Pill Cauldron, controlling the flame and simultaneously removing impurities.

Seeing this, many were shocked. To refine a Yin-Yang Rejuvenation Pill in this manner was something even a regular Authentic Alchemist would not dare to attempt.

"This youngster really has some skills."

Du Yan nodded slightly. If not done this way, it would be difficult to refine a Yin-Yang Rejuvenation Pill within the time of one incense stick.
