Yang Meng, 23 years old, is the new leader of Lieyan Camp, codenamed "Mute Boss".
On the surface, she is an ordinary transfer student in the middle grade of Nanyi International High School - introverted, quiet, and inconspicuous. She sits in the last row of the classroom every day, ignored by her classmates, bullied by school bullies, and even the teacher can't remember her name.
But no one knows that this "introverted female high school student" is proficient in riding and shooting, fighting, cryptography and intelligence analysis; no one knows that she holds the most secret power in Nancheng; no one knows that she is carrying out a secret mission - to investigate the truth behind the Lin family's sudden increase in power and to find her master Shen Ye who disappeared a year ago.
Shen Ye was the previous mute boss and Yang Meng's only relative. The last clue she left before her disappearance pointed to the Lin family's old house, an iron door numbered 0-7, and a secret that had been sealed for fifteen years - Area A technology.
As the investigation deepened, Yang Meng discovered that her forgotten childhood was closely connected with all this: her memory before the age of eight was blank. She did not know where she came from or who her biological parents were. She only knew that her name was given by Shen Ye.
And the man who has been following her - Shen Baizhou, Shen Ye's brother, may know the answer.
At the same time, she was forced to deal with various characters: Lin Chenlan, the cold and aloof heir to the Lin family, Chen Jingtian, the perfect and gentle young master of the Chen family, Chen Jingkong, an introverted and kind-hearted medical student, Wu Lulu, a wealthy daughter who flaunts her delicate heart on the outside, Wen The gentle and upright teacher Yuan Xiaochen, and the police officer Gu Ke who is persistent in investigating the black market case... They were unknowingly involved in this whirlpool, and unknowingly, they developed a different affection for the transfer student who always kept his head down and was quiet.
But Yang Meng had no time to respond to anyone's feelings.
She had to find the door. Shen Ye must be found. You have to get your past back.
And when the truth was revealed bit by bit, she discovered that Shen Ye's disappearance was not an accident, the rise of the Lin family was not a coincidence, and there was a secret hidden behind Area A's technology that could subvert the entire X world. And she herself is part of that secret.
"Xiaomeng, I'm going to Nancheng to do something. I'll be back soon."
——These were the last words Shen Ye left for her.
It's been a year. Yang Meng finally found the direction of the answer.
But behind that door, is salvation or an abyss?
Intention: There are some truths, once you know them, you can never go back.
