The top scroll king Jiang Xian accidentally entered the harem, and was bound to a not-so-smart "Erha" system. While others fought to the death in the palace, Jiang Xian turned the harem into a modern workplace: the spoiled queen was her "boss", the arrogant concubine became her "best friend and colleague", and the Queen Mother couldn't help but sigh, "Fortunately, she retired early." As for His Majesty the Emperor? They are just the ultimate target customers that she needs to "strategize" on her way to promotion. With her superb professional skills, Jiang Xian thrived in the harem. Promotion and salary increase? That's just basic operation! Her goal is to turn the entire harem into her comfort zone! There is no smoke of palace fighting, only the sweat of King Juan's struggle (and the occasional tears of being cheated by the system).
