On the day of separation, Shen Yan was hit by the system: a handsome boss would be sent to him every day, along with a clue to an old case. But every time the clues are fulfilled, the enemies will keep an eye on him one more point. Ex-wife Jiang Ning came to the door with a caravan, holding half of the old accounts in her hand - the ironclad evidence of the Shen family's murder. The two were forced to join forces, while dealing with the temptation of Pei Zhao, the young minister of Dali Temple, and buying the remaining pages from the intelligence dealer Lu Zhao. But his stepsister Liu Ruyan suddenly changes sides, and the accounts of Zhao Wujiu, the Minister of Household Affairs, are also exposed. Shen Yan discovered that each 'handsome boss' rewarded by the system corresponded to a key figure in the old case, and the last one was actually the son of the chief prosecutor. When all the old accounts were spread out, Shen Yan realized that the system was not a golden finger, but a belated reckoning. He wants to settle every account between enemies, allies, and old loves, even if the price is to lose everything again.
