Within the Zhenhai Team, there were two people who were particularly difficult to investigate.
One was Chen Lingyun, after all, she was the only daughter of the Jianghai Governor, and naturally, interacting with her required utmost caution;
The other was Zhao Yuanzhen, for a simple reason: lack of background information.
Zhang Jin couldn't obtain Zhao Yuanzhen's personal information, and had even gone to inquire with the department head beforehand. The result was that the department head told her she didn't have a high enough security clearance, "Anyway, lacking background information doesn't hinder your communication with her," which made Zhang Jin somewhat suspicious.
Could she be the illegitimate daughter of some big shot?
This possibility couldn't be ruled out, so Zhang Jin decided to treat her with the same caution as she did with Chen Lingyun. Techniques like the ones she used to deceive Lin Ning before, definitely couldn't be used on Zhao Yuanzhen.
