Reborn as Prince Carlo of the House of Savoy in 19th-century Italy, a modern soul finds himself the favored son of King Victor Emmanuel II. Though blessed with royal privilege and a doting father, Carlo faces the harsh realities of an era lacking modern medicine and technology, highlighted by the mysterious death of his beloved brother. Determined to seize control of his destiny, Carlo sets his sights on a fleeting historical opportunity: the Spanish crown.

With two older brothers blocking his path to the Italian throne, he devises a cunning plan to outmaneuver them and claim the kingdom of Spain. To fuel his ambition, he secures his massive personal annuity and recruits Luo Lun, a brilliant and loyal administrator. Together, they begin building an empire of influence, starting with the strategic acquisition of 'The Sun Newspaper' to master the power of public opinion.

In a world of royal intrigue and impending revolution, Carlo must navigate political schemes, amass wealth, and manipulate history itself to rise from a protected prince to the monarch of a new empire.
