Although the whole family was anxious for Ray to speak, Mo Shan was not. He just gave his daughter time because he knew she will definitely speak one day. This was what he thought, but he didn't think that his daughter will soon speak the first word. And her first word will enslave him to her. Her first was none other than 'Dada'.
What happened was, after they found her in Old Madam Mo's room, they were relieved at first. But after a while, Yun Xi calmed down and was about to chide her daughter for it. Ray noticed her change in expression, she knew she was going to get scolded now. So, before her mother could speak, Ray cutely leaned her head against her father's chest and called, "Dada!"
The word of hers sent a shiver down his back. He could not react for a while. Even the family members froze at her cute voice. They could not believe their words. "D-did she just speak?" Mo Sheng stuttered. Everyone came to their senses at Mo Sheng's words.
