At 9:20, Qiao Nanchu received a call from Zhou Xufang, who sent him a video of Wen Baiyang being kidnapped, "Baiyang might have a tracking device on her, the receiver is in her computer."
It was Shuangjiang's own doing; they each had a pair of earrings equipped with miniature tracking devices.
Zhou Xufang didn't dare to be careless, providing as many details as possible: "But her computer might be tough to crack. I don't know where her work computer is kept, but it should be very close to where she lives. It's a five-minute walk at most."
They had undertaken many missions at night; sometimes, after Shuangjiang finished her part, she would go back to sleep. It wasn't long before or after, which indicated they were very close.
Qiao Nanchu got the gist, "You know it's her?"
Zhou Xufang was also surprised, "You know too?"
She found out about Shuangjiang's identity on New Year's Eve. Qiao Nanchu had suspected earlier, from the moment he saw her strawberry elastic hairband.
