I Bound a Fake Heiress to the Truth-from-Lies System

Ji Fei was the genuine daughter of the Ji family, but as a child, she was swapped for the fake heiress, Ji Lu, by her mother and raised in a poor mountain village. Her only warmth came from her mentor, Zhou Fen. However, when Zhou Fen was falsely accused of academic misconduct and sexual harassment by Ji Lu, she committed suicide due to depression, leaving Ji Fei heartbroken. At that moment, a system appeared, revealing the truth about her stolen life and offering three golden finger options. Determined to avenge Ji Lu and honor Zhou Fen's spirit, Ji Fei willingly traded 20 years of her lifespan to activate the 'Truth-from-Lies' system.
