Modern girl Lin Zhiwan accidentally falls into the water and transmigrates into a book, becoming Shen Zhiwan, the doomed legitimate daughter of the prime minister’s household.

In her darkest hour, a mysterious iron box connects two different eras.

Her modern-day older sister, Lin Zhixia, has the complete original novel’s plot and becomes her only support.

The iron box lets them talk across time and send supplies to each other.

Pretending to be simple-minded, Shen Zhiwan carefully plans every move, relying on her sister’s warnings from afar and the help of her loyal maid, Qingdai.

Again and again, she escapes plots involving poison, false accusations, and ruinous scandals. She tears up her sham betrothal and joins forces with Xiao Jue, a prince with real power.

Following the clues hidden in the household intrigues, she uncovers the bloody vendetta behind her birth mother’s murder and gets swept into a shocking conspiracy at court involving the princes.

She gathers evidence of embezzlement and collusion with the enemy, breaks into secret chambers, and attends banquets laid to trap her, fighting to survive amid bloodshed and turmoil.

With her vengeance fulfilled, the iron box’s ultimate secret is revealed on the night of the full moon.

Now she faces a difficult choice: stay in the past and accept the prince’s love, or return to the modern world and reunite with her sister?
