"Bai Qingyu! Stop for me!"
"Who do you think you are, that you can do whatever you want me to do?"
"You woman, when I catch you, you will look good!"
...
Bai Qingyu, the peerless agent of the 21st century, is codenamed "Xuan". High-level officials all over the world are frightened by this news, and as long as they are prey targeted by her, they will never escape from her clutches. Everyone who had seen her said they didn't know whether she was a boy or a girl. All they knew was that she wore a silver mask on her face, and the light suddenly appeared, making people feel cold all over. Bai Qingyu herself behaves like a good girl during the day, busy with patients in the hospital, and everyone she saves calls her "beautiful and hard-working angel"; but once night falls, she transforms from an angel into a demon, takes off her flat eyes, wears black tights, a silver mask on her face, a silver gun at her waist, black hair tied up, and an ink-colored cloak. What is even more frightening is her pair of bloody eyes. No one knew that those bloody eyes were her natural eye color.
Her parents died when she was young, and her grandfather raised her single-handedly. It wasn't until she was six years old that her grandfather passed away, which prompted her to go down that dark path. What led her to the dark abyss was the desire to avenge her dead family members.
And her final mission is to steal the thousand-year-old spiritual jade - Lingjun Jade Pendant. Unexpectedly, she met her enemy directly. In that battle, Bai Qingyu, an eighteen-year-old girl, died...
Bai Qingyu, the eleventh-year-old good-for-nothing fourth lady of the Prime Minister's Palace of Lanli Kingdom, was driven to a run-down town at the foot of the southwest mountains four years ago with her mother Qin and her younger brother Bai Zerui. But she didn't know who framed her, and carried her directly to a pile of dead grass deep in the mountains, with the intention of burning her to death. However, in the process, the soul in Bai Qingyu's body had already been transformed.
"Don't worry, since I have taken over your body, I will definitely help you get revenge. I, Bai Qingyu, will do what I say."
"Thank you sister, sister, be careful in everything. Qingyu will bless you in the sky."
...
With a "whoosh" sound, a hidden arrow was shooting at Bai Qingyu. Bai Qingyu dodged it very deftly, but there was a cold snort from behind. Only then did Bai Qingyu realize that there was someone behind him.
This is how they started...
