The Romantic Housekeeper: the Opening Perfume Alarmed the Empress

[After traveling through time and becoming a servant, you will be sold to mine at the beginning? Fortunately, I brought a head full of modern knowledge - making soap, making perfume, doing finance, playing with gunpowder... I wanted to just be a wealthy idler, but I was forced to get involved in the struggle for imperial power. The eldest princess wants me to be her sword, the cool businessman regards me as a forbidden concubine, the talented woman loves and hates me, the saint of the enemy country wants to take my life, the enchanting spy always wants to climb into my bed... Above the temple, I use science to defeat tricks and economy to kill evil hands. Across the rivers and lakes, I used gunpowder to quell rebellions and used public opinion to stabilize people's hearts. From a low-level servant to a governor, from a merchant soldier to an emperor's regent. When the empress I assisted ascended the throne, and when the wheels of the empire I created rolled over the old era, everyone was shocked: All the romance in the world is in the palm of my hand as a "servant". --- "The Merry Butler" - see how modern elites fought their way through ancient times, used technology to crush conspiracies, used wisdom to harvest hearts, and finally became the chess players behind the scenes!
