The protagonist of the story is Xinran, a 19-year-old girl with a sharp knife skill of "Breaking Door Knife" and a character that hates evil as much as hatred. She cherishes the dream of a knight who "kills one person in ten steps and leaves no trace in a thousand miles", but she encounters obstacles everywhere in the modern city and almost turns herself into a "problem girl".
A brave act of justice brought her into contact with the genius doctor Gu Shen. Gu Shen opened the door to a new world of martial arts for her, but he also told her: "Your knife is too sharp and will hurt others and yourself. Sooner or later it will break." Under Gu Shen's guidance, Xin Ran embarked on a more rational and far-reaching path of martial arts, and began to use martial arts to help people who really need help.
However, they were involved in a serial conspiracy targeting "martial arts practitioners". He was delighted to find that his proud kung fu was vulnerable to a real killing move. The "Broken Gate Sword" in her hand was really broken, but she wanted to use it as a starting point to resume her martial arts and life.
Character settings:
Xinran (female protagonist): 19 years old, 168cm tall, a freshman in the Physical Education Institute. He has short hair and sharp eyes, like a little leopard ready to attack at any time. He has a straightforward personality and believes in "trying to be hands-on without making any noise". He values love and justice, but sometimes gets into trouble due to impulsiveness.
Gu Shen (male protagonist): 24 years old, a medical genius. On the surface, he appears to be a calm and reserved surgeon, but in fact he is an authentic successor of Baguazhang. He is like a sword hidden in a scabbard, hidden from view. Rationality and calmness are the most important guides on Xinran's growth path.
