After making the Healing Potions, Ang carefully packed them into the Demon Sealing Boxes he had prepared beforehand, ensuring they would retain their potency during long-term storage. When he handed the Demon Sealing Boxes to Ernit's nephew, Ben, Ang noticed that Ben still looked a little dazed—over the past two days, he had been continually stunned by Ang's assembly-line technology.
"This time, I've given this setup a name: the 'Magic Potion Production Line.'" Ang smiled at Ben. "It will greatly improve the production efficiency of magic potions."
Ben seemed not to have fully recovered from his shock. He mechanically put away the Healing Potions while scenes of the production line's efficiency kept flashing through his mind. To Ben, this method of production had completely overturned his traditional understanding of potion-making. Then, he took out the payment for this batch—Magic Crystals—from his bag and prepared to hand Ang his compensation. This time, Ang had decided to use Magic Crystals to pay Master McGovern.
After Ben left, Ang began cleaning up the production-line equipment used this time. He remained meticulous and rigorous in cleaning the line, because he knew that the residues being cleaned away were not merely waste; they still contained quite a few valuable potion ingredients. During the cleaning process, Ang used his own method to extract the residue and unexpectedly obtained four standard-sized bottles of Healing Potion.
After settling the profits from this batch production, Ang made a rough calculation. Each time he produced Healing Potions, he could usually earn 380 Magic Crystals or magic materials of equivalent value as payment. The four extra bottles obtained during cleaning could also bring him some income. Healing Potions sold for five Magic Crystals per bottle on the market, so the total income this time was close to 400 Magic Crystals. Considering
