Shock! The Eye-Candy of the Entertainment Industry is Reborn as a Top Student!The niece of the Zhang family is said to be the reincarnation of the God of Literature. From childhood to adulthood, she has never scored second place in any exam. Even on the day of a test, when she had a fever of 39.9 degrees, she still effortlessly wrote like a supernatural being—truly amazing.When neighbors talked about this girl, their envy and astonishment were indescribable.This girl was nothing short of a Tsinghua or Peking University candidate; the Zhang family’s ancestors must be smiling from their graves.“Have you heard? That Zhang family girl topped the citywide high school entrance exam again. City No. 1 High School and Experimental High School nearly fought at the Zhang family’s door to recruit her...”“What’s that? The principal of Lanya Noble High School even came with a million yuan to visit her…”The world of a top student is beyond our understanding!——The world of a top student is very lonely!——When one possesses unparalleled beauty but lacks status and power to match it, this becomes the root of all suffering.In her past life, Shen You'an refused to compromise with the hidden rules of the entertainment industry. Her life was one of hardship and destitution, ultimately ending in her dying alone on a snowy winter's night on the streets.Once celebrated as the stunning but talentless beauty of the entertainment world, she left quietly and tragically, without drawing attention from anyone.When Shen You'an opened her eyes again, her firefighter father had just passed away in the line of duty.“Ding.” Your System for Top Students has arrived. Please sign for it.She cut her long hair, put on glasses, and concealed her beauty. Thus, she began her journey to becoming a top student.Until she gains the strength to protect her unrivaled beauty, she would rather let her brilliance be hidden than become a target of envy and harm.

Right after transmigrating into a parallel world, Yang Yi was a bit stupefied upon seeing a adorable little girl calling him father. Fine, Xixi is 100% my daughter, but my child’s mother is actually an aloof, absolute beauty who’s a famous singer.

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.
