Use Knowledge to Make Civilian Magicians Bow Down in the Demon King's Castle

Chen Sen, a doctor of physical and chemical materials, transformed into a bloody demon king who was ridden in the face by a brave man. In order to survive, he was forced to use "dust explosions" to disguise forbidden spells and "chemical reactions" to pretend to be miracles. The subordinates trembled: "Your Majesty has mastered the truth of the world, it's so evil!" The brave man was horrified: "The Demon King is accumulating the world-destroying thunderbolt, it's too scary!" Chen Sen collapsed: "... I really just want to synthesize chemical fertilizer to grow potatoes!" While suppressing the bloodthirsty demonic instinct in the body, he led a group of subordinates who regard science as black magic. If they learn mathematics, physics and chemistry well, they will not be afraid of traveling around the world!
