Reborn as a Spoiled Heir: From the Start, I Conquer the Capital with Strong Liquor

Lin Yuan, a modern history PhD, wakes up as the second legitimate son of the Jing'an Marquis's household and one of the capital's most notorious playboys. Everyone thinks he's a hopeless waste, but armed with modern knowledge and a mind that can run simulations, he sets the world in turmoil with strong liquor, glass, cement, and gunpowder. As the Northern Di tribes ride south and princes spill blood over the throne within palace walls, this playboy, once rejected in an arranged marriage, will become the uncrowned emperor who decides the dynasty's fate.
