Why did she wait for five years?

Li Xue's eyes suddenly became like fire as her fingers lightly pressed the power button of her phone. Then turning around she looked at the Principal. "Sorry for this trouble, ma'am. But don't worry this chaos outside will not remain for long. The moment I go out they will leave along with me and your school premises will be out of this chaos."

"I still can't stay here for long. Since there is no clue at school I can only go around to check. My daughter is still not with me and I need to get her back." She said but something in her tone felt really relaxed like she was no longer anxious for something. Like she has already got a great hint of the things or has understood what everything was aimed at.
