She would rely on her capability to catch the attention of the military's higher-ups and occupy a position that no one dared to touch. If she investigated the truth behind her mother's sacrifice then, the resistance she would face would be lesser.
That was the truth.
The military and the Military Discipline Commission's involvement allowed her to stay out of this matter and not be targeted by the forces behind the jade. It was all because… the military was protecting her.
Captain Xia reported everything to Commander Xia. Commander Xia then reported it to the Military Discipline Commission. The Military Discipline Commission secretly formed an investigation team to protect her.
Hence, no matter how much she wanted to know who killed her mother, she couldn't let down the people protecting her because of her rashness.
