Using his Divine Synthesis, he reverse-engineered basic healing potions into a streamlined formula. He built distillation devices, automated stirring rods (enchanted, of course), and even designed a Potion Assembly Line powered by mana crystals.
Within weeks, his first batch of "Sato's Supreme Elixirs" hit the market - cheaper, faster, and stronger than anything else.
