Synopsis：Arthur Sterling wakes to find a scantily clad beauty in his arms, but before he can enjoy the moment, his uncle, Duke Edward, kicks open the door and accuses him of violating Edward’s fiancée. Only then does Arthur realize he has time-traveled into the body of Valoria’s hated, useless Crown Prince! Faced with such an obvious setup, Arthur fights back, calls in his eunuch attendant to testify—only to discover the entire Crown Estate has long been bought by Duke Edward. Every servant is a spy! Enraged, Arthur cuts down the treacherous lackey with his sword and even slaps Duke Edward across the face. Just when he thinks the only path left is a bloody showdown, a chime sounds in his mind: he has unlocked the “Prestige System,” which lets him exchange prestige points for modern weapons—planes, cannons, firearms, and more! Humiliated by the slap, Duke Edward swears to impeach Arthur at morning court. The next day, his faction besieges the throne with accusations; the weak king wants to shield his son but cannot truly control the court. Armed with the System, Arthur feels no fear. In front of the entire royal court, he unveils modern firepower, ruthlessly executing the traitors and seizing power in his father’s name to begin a sweeping purge of the realm. After his first scheme fails, Duke Edward stirs up superstition, claiming the decade-long drought proves the Crown Prince has lost all virtue and the Celestial Mandate. Arthur publicly shatters this lie by creating artificial rain! Just as he moves to wipe out Edward’s faction for good, arrogant foreign envoys arrive—revealing that Duke Edward has already colluded with them to spark a rebellion. At this critical moment, Arthur uses the System to turn the tide, crush the rebels and invaders, and restore Valoria’s lost glory!
