Fake Eunuch, Three Brides

Lord Cameron, the prince of a different surname of Daphonn, rebels and commits regicide. He humiliates the orphaned royal Julia Fisher, the female commander of the Imperial Guards General Stanton, and Consort Vertu Lauren Carlisle by marrying them as wives and concubines to the eunuch Dylan Mercer. However, little does he know that Dylan is a time-traveler equipped with a favorability system. He protects the three women, breaks out of the Royal Chambers, and establishes a base at Dreadfang to recruit troops. On his path of revenge, he destroys the rebels, rises to power over the realm, and wins the hearts of the beautiful women.
