Yun Meiyi could see that the woman staff was still in a slight worry state. She was making calls for all necessary arrangements and was coordinating with the people. The situation seemed quite serious. 

And the more serious it seemed; the less Yun Meiyi could think what she should do. She was still in her daze when she heard her grandfather's voice from the other end of the call. "Yi Yi, is everything fine there?" 

It was then Yun Meiyi realized how ignorant she was of the situation. She might not have met him, but he was their guest. She couldn't be like this. With that thought, her brows jutted together and she quickly responded to her grandfather. "Grandpa, there is something I need to look into. I will call you later." 

Yun Chang Hai felt something amiss. But since Yun Meiyi didn't tell him, he simply affirmed her with a hum. And the next moment the call was disconnected.
