Qin Hai's talk of luring the snake out of its hole was actually about using the sisters, Meiya and Meirou, to attract people from Evil Shadow. He could use the sisters' disappearance as an excuse for Yang Guang to seek help from Evil Shadow. Since Evil Shadow had promised to be responsible for their clients for life, they would definitely send someone over upon hearing the news, and then an opportunity would arise.
However, this would inevitably affect Meiya and Meirou, even putting them in danger, so Qin Hai wouldn't consider this method unless he had their consent and it was absolutely necessary.
After He Meimei left, Qin Hai's sleepiness was completely gone. He sat in the office for a while before getting up and strolling to the doorway of Qiao Wei's office.
The door was slightly ajar. Pushing it open, Qin Hai saw Qiao Wei leaning over her desk, busy with something. Because Qiao Wei had her back to the door, she didn't see him come in.
