There is a mystery hidden in his father's old work notes. Tang Kaifeng entered the agency just to find out.
But the job in Jinning City was not as simple as he thought: some people handed him "trouble-saving tricks", while others were "careless" about old clues. Even the old information he was looking for was always "unable to find" at the critical moment.
On the one hand, he saw the opportunity to move up if he worked hard, and on the other hand, when he visited, the eyes of the people holding his hand and saying, "I hope for a sure word" - Tang Kaifeng was not relaxed.
The numbers in old notes, the past that no one wants to mention, the topics that always get sidetracked... The more he checked, the more he felt that his father's "questions" back then were not simple.
The road to find the answer was not easy, but he was determined: not only did he want to give his father an explanation, but he also wanted to make sure that people who came to ask questions didn't have to make the trip in vain.
