Gu Qixiao didn't react upon hearing those words. He simply instructed his men to continue keeping an eye on Ji Yu.
At the slightest sign of trouble, they were to notify him immediately.
As for the things Lin Chujian said, he didn't dismiss them entirely, because he knew such circumstances were bound to happen. That's why he chose to ignore Lin Chujian.
But she, apparently having plenty of time, really waited downstairs all night.
When she saw him, there was a hopeful glimmer in her eyes. "Gu Qixiao, I hope you can listen to me properly. I know you must despise the Lin family, but this matter isn't what you think it is."
As she said this, she approached Gu Qixiao and even grabbed his sleeve.
Gu Qixiao expressionlessly pulled her hand away. "I don't care whether the Lin family is good or bad. Once you've taken things to this extent, don't even dream of turning back."
Since they wanted to make a move against Ji Yu, they were simply asking for trouble with him.
