Secretary Zhou followed Rong Yan into Liancheng Yazhi's study.

There was a lot of confidential information in Liancheng Yazhi's study room, but he had never set up any defenses against Rong Yan.

Rong Yan sat in front of the table and placed her hand on the fingerprint input area on the drawer. Soon, with a beep, the drawer popped out automatically.

There were many things in Liancheng Yazhi's study. Safes, drawers, and bookshelves all used fingerprints. In the system, only his and Rong Yan's fingerprints could be used. Other than him, only Rong Yan could open it.

Rong Yan took out Liancheng Yazhi's private seal from the drawer and pushed it in front of Secretary Zhou. "Secretary Zhou, you can take it."

What was the use of Liancheng Yazhi's private seal?
