In this short scene, cynnie is trying to figure out what has happened to the qi family. She realizes that her sister didn't go to the engagement party, which means she's not bound to the seal magic and can tell everyone the truth about what happened. She also realizes that the man who looks like lin is her brother, and that he's the one who killed lin. . She tells him that the people who attended the party were put under seal magic by lin, and if they tell the truth, they'll all be killed by her seal magic. She asks him to repeat the words that lin said: "she'd activate her key of reconstruction" . He's afraid to repeat it, but he does it anyway, because lin put him under the seal to keep quiet. He and lin have lied a bunch, but they just want to use the opportunity to get rid of the family because of all the nasty things they've done behind the scenes
