How Can You Be the Prime Minister of France Without Making Money?

I would like to ask, in seventeenth-century France, how could a time traveler "hold the emperor hostage to command the princes"? Clement Gironde slapped all the Bibles and muskets in his hands on the table: "Can I rule based on the Bible?" "Okay, stable enough but not fast enough." "Can you take power with a musket?" "Okay, fast enough but not stable enough." "Can the Bible + muskets quickly and steadily take power into their hands?" "May I ask who your lord is?" "The next Prime Minister of France." "Welcome to Clement Buwei, Zhao Gao, Mengde, Cai Jing, Yan Song, Heshen and Gironde!"
