In a realm where even the faintest shadows whisper untold tales, I came to realize that the forgotten often hold the most powerful narratives.As an avid admirer of the world's most beloved series, I never imagined that one night's rest would pull me into its very fabric.“Why on earth am I stuck in this world? And why, of all people, am I him?”I had become Arthur Nightingale—Class A’s most unremarkable student. A magic swordsman barely worthy of mention, ranked 8th among the first-years. A mere footnote in the grand story.Still, with this body’s abilities and my own insider knowledge, I figured I could carve out a peaceful life. Or so I believed.“This was the only way,” the voice repeated, resolute. “The only way to stop her.”Little did I know how truly unique Arthur Nightingale was—or the path this journey would force me to take...

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.

“I was abandoned by you over and over again. Now you want to use familial affection to coax me back. You don’t want to recognize this daughter. My heart is cold, I want to leave. Beat it, father!”
