Dressed as a princess of the Ming Dynasty, Lin Weiwei just wanted to lie down. However, the professionalism is too hard-core and the strength does not allow it! Glass too blurry? Watch me optimize the transmittance of the formula! Is rouge poisonous? Independently developed natural color from plant extracts! The prince's husband suspected that my identity was fraudulent every day, so he tried various methods to test: "Princess, what is the principle of this thing?" "Princess, is there any record of this method in the classics?" Lin Weiwei took out a stack of "ancestral secret recipes" filled with English charms and force analysis: "Your Majesty, this is the secret knowledge of my hometown..." I wanted to fool myself, but accidentally - solved the Yellow River flood? Improved military equipment? Even... Attracted the emperor's attention? Seeing that the little vest was almost unable to cover itself, the prince blocked her in the laboratory: "Weiwei, where is your hometown...?" "Also, the way you look at the drawings is much more eager than when you look at me... Huh?"
