Mu Xiao's rare loss of composure instantly made Mu Cheng's expression turn even more serious. "Why can't we investigate? What are the two of you doing? Could it be that it's really as the rumors say? The two of you are so ridiculous that the two of you share a woman? You even got that girl pregnant?"
Mu Cheng knew that this was unlikely, but in order to force the two young brats to tell the truth, he could only say this.
"Dad, it's not like that! Yinyin isn't such a girl. Don't talk nonsense." Mu Heng frowned deeply, thinking about how to tell his father.
Mu Xiao could not hold it in anymore. He made up his mind and said, "Yinyin is Tian Tian!"
Mu Cheng, who was still questioning her sternly just now, was instantly stunned.
He asked in disbelief, "What did you say?"
Since she had already said it, Mu Heng did not hide it anymore. "Yinyin and I did a DNA test. Yinyin is our biological sister, Tian Tian!"
