After she transmigrates into a book as Lin, a low-ranking concubine destined to be cannon fodder in a palace-intrigue story, Lin Wanwan decisively clings to the powerful regent, a cold-faced god of war, to escape a death sentence by white silk. She plays dumb to avoid trouble, repeatedly saves influential people with her unmatched medical and poison skills, and uses their power to take down a wicked consort. The regent, who originally meant to use her, is gradually captivated by her cleverness and cunning. He showers her with affection and clears away the obstacles in the harem. In the end, Lin Wanwan turns the tables and survives to the finale. The regent even gives up power to stay by her side, and together they enjoy a life of wealth and glory as they watch the palace's intrigues unfold.
