Lu Chuan, a staff member of the grassroots liaison office, came from an extraordinary background. He could have risen to the top, but he had to start from the bottom.

An old case, a ledger, and a missing person involved him in a chess game that he didn't expect. This is a story about choices, bottom lines, and growth.
