After Being Tortured, I Became the World's Greatest Martial Artist by Hitting Where It Hurts

Yuan Chujun, a princess of a fallen kingdom and the most beautiful woman under heaven, was struck by a hidden guard forced to hold back so he wouldn't accidentally kill her while protecting her from the enemy. Unfortunately, the whip was coated in poison. As the hidden guard, who was also the male lead, regretted his actions, she died alone. From then on, a crack formed in the male lead's heart. He ventured into the martial world and eventually became its greatest fighter. After completing a mission for some rich young lady to test whether her boyfriend was cheating, Yuan Lucha was struck by divine retribution and became this poor princess. She laughed. "He hurt the princess so badly while trying to make sure the enemy wouldn't hurt her... What a classic." She had been ready to turn over a new leaf and start afresh, but the poison had already destroyed the nerves in her legs. The first time in her life she found herself sprawled helplessly on the ground, she was furious. No one's ever dared make me suffer a loss! The princess, huh? I'll get revenge for you! So, with the Heart-Piercing Level-Up System, Yuan Lucha uses her practiced green tea tricks and acting skills to make the vanished poison seem like an incurable disease that is gradually devouring her five senses. With nothing but her face, she slays her way through the martial world. The gentle woman sits in her wheelchair and lowers her eyes slightly at the male lead, the villain, and the male lead's admirers around her. "...I'm just a cripple from a fallen kingdom..." In an instant, countless swords are drawn. With a fingertip lightly touching her lips, Yuan Chujun's eyes flash brilliantly when no one is looking. [Well, he's just an ordinary number one in the martial world.] * Her smile breaks when Xuan Jing, the former hidden guard, walks in with a bowl of medicine and speaks softly. "Your Highness, it's time to take your medicine." As Xuan Jing watches in shock, Yuan Chujun coughs up a mouthful of blood. The "half-dead" woman leans against Xuan Jing's shoulder, her gaze firm. The greatest fighter in the martial world doesn't need to take medicine! P.S.: 1. 1v1 throughout. The male lead has one-sided feelings early on. 2. The heroine uses a harem-favorite persona to build her career. 3. Some side characters have one-sided feelings for the heroine, but the romance is 1v1 throughout. Xuan Jing is the only male lead.
