A Di [legitimate-born] daughter of a noble house turns into an abandoned daughter. No father to dote on her, no mother to love her, no problem. She uses one silver needle to save a dying man. What’s so unusual about a medical injection? She roams all over the world with a scalpel in her hand. Cutting throats, cutting open abdomens, cutting open skulls to mend bones. With amazing medical skills and ethics, she gathers a flock of officials, obtains the will of heavens, gains public favor, and receives Taizi’s [Crown Prince] doting. In the midst of a powerful momentum, her cheap father comes to reunite. She coldly refuses to go home or acknowledge ancestors.

Rong Qingyan is a 21st century successor of a medicinal family, proficent in medical knowledge. But in the end, she has died in the hands of her relatives. Murong Qingyan is Sheng Hong Continent’s Murong family’s legitimate miss. But even though she is a legitimate daughter, she is the Murong family’s shame because her appearance is ugly and her meridians are blocked, making her a trash that cannot cultivate.

After she transmigrated, she became her.

When she reopened her eyes, the originally unable to cultivate trash let everyone stumble in shock. Flipping over clouds, going against the heavens and changing fate, letting those that originally looked down on her regret it deeply.

Contracting magical beasts, concocting immortal pills. Meeting gods, killing gods; meeting Buddhas, killing Buddhas; swearing to let all those that looked down on her see her in a new light.

When the trash turned into a universally shocking prodigy, when the ugly appearance was shed off, she was no longer the original her. In the whole course of events, whose heart did she actually steal?

Her ex fiancé regretted it deeply, but to no avail. The family that looked down on her is now immensly remorseful, yet they can’t change anything anymore.

When she stood at the peak of the world, he was always by her side protecting and guarding her, letting her be able to freely soar in the sky.

He said: “In my life, I wish for nothing else. I only wish to love you forever.”

She said: ”If it is what you desire.”
