After the potion was done, a sharp whistling sound came from the vent holes in the iron pot.
This whistling sound was different from the usual noise when water starts boiling.
Inside the pot, because the Essential Qi of the herbal medicine was swirling, the sound was much louder than usual.
It was like the roaring of dragons and tigers, so intense that it made one's ears tingle.
Bald Dog hummed excitedly, "Indeed, it's the Alchemy Rules. This master is capable!"
Lin Yingying, however, exchanged glances with her sister, thinking that the pot might have boiled over.
Long Fei turned off the gas stove, and the noise stopped.
He poured the herbal medicine into bowls, two in total, and brought them out to them.
The herbal medicine was black in color, looking like a layer of grease.
If Long Fei had used his spiritual power to manipulate the Pill Flame during brewing, he could have filtered out all impurities and purified it.
