"Alright, both of you. Let's start the lesson to refine the Blood Clotting Pill. With an Ash Willow Bark around this size, it is roughly enough for five pills to be made..."
"Because the amount of Spiritual Energy you have is limited, you girls will have to first grind the bark into a powder form before you can proceed. After that, the powder would have to be steamed to bring out the anesthetic effect."
"Now, after the steaming process is completed, you'll have to start to roll an adequate amount of the wet Ash Willow powder with some Medicinal Ash. This way, it will be easier to create pellets with a smooth surface."
"But that was not all. After separating the mix into the standard pellet shape, we'll have to cook it inside the cauldron for an hour until the color on the surface changed into dark brown. Only by then, the Blood Clotting Pill is counted as a success." Qin Lan patiently taught the twins without noticing how fast the time had passed.
