Nan Yan wasn't that kind-hearted.
The reason she wanted to release him and provide medical treatment was simply to use him as a means to gain information about the so-called "Seven Sins," an organization that even Qin Lu was unaware of.
It couldn't be denied that Qin Lu understood her quite well.
After they emerged from the underground, she hadn't mentioned where she wanted to go. Qin Lu immediately started the car and drove her to the First Hospital.
On the way, he made a phone call and requested a tracking chip, an implantable one, to be inserted under the skin. It had no adverse effects on the body and wouldn't be easily detected.
Nan Yan lazily propped her head up and asked, lips curved, "Brother, how do you know what I want to do?"
Qin Lu casually replied with three words, "Make a guess."
Nan Yan shot him an unceremonious glance, "I won't guess. If you're willing to tell, then tell. If not, forget it."
