The Legitimate Daughter Returns: The Mad Crown Prince's One True Love

Substitute marriage + secret identity + real and fake heiresses + a ruthless crown prince's journey to win back his wife

Shen Heng is the true eldest daughter of the Shen family of Jiangnan, but she was raised for eighteen years at an estate outside the city as an “ill-omened child.” The fake heiress, Shen Mingzhu, took her place, becoming the capital's most celebrated beauty and scholar, and was even betrothed to Crown Prince Xiao Yan.

On the eve of the wedding, Shen Mingzhu eloped. To save face, the Shen family brought Shen Heng back from the estate and forced her to “marry in her sister's place.”

On their wedding night, Crown Prince Xiao Yan lifted her veil and sneered. “A substitute thinks she deserves to be my crown princess?”

Shen Heng lowered her eyes, her voice gentle. “As Your Highness says.”

No one knows that

She was once “Bluebird,” the secret leader of the imperial guards trained by the late emperor, and at thirteen she put down a rebellion in the southwest on his behalf.

She holds irrefutable proof that the regent has colluded with the enemy and betrayed the country.

Her medical skills can make even the dead speak.

And Xiao Yan, the man she once saved with her own hands, only to push away herself, is now the lofty crown prince. Little by little, he is discovering that this “substitute” is far more dangerous than he ever imagined.
