The Secret Manual to Harem Domination

"A harem strategy expert transmigrates as the cannon-fodder empress in a harem novel. Knowing full well that she and her powerful general clan will eventually become thorns in the emperor’s side, she chooses a wildly unconventional path. On her first day in the palace, she drains the lake and digs deep to prevent all plots and frame-ups; she sends the emperor three hundred concubines, leaving him overwhelmed by so many royal heirs that he wants to castrate himself. When the destined heroine Lin Wanyin enters the palace, all her classic schemes are easily countered by Li Mingyue’s preemptive defenses."
