His father was framed and the grain delivery was about to be delayed. Shen Lingyi escorted the grain on his father's behalf and arrived in the capital within three months. But as soon as she entered the waterway, she encountered river bandits who robbed the boat. More than half of the boatmen were killed or injured, and the grain bags sank to the bottom of the river. Using an exquisite dice as a token, she sneaked into Caobang to check the accounts, and discovered that there was a shocking embezzlement case hidden in the account books - someone in the court colluded with water bandits, resold the official grain, and then reported the loss as a shipwreck. While tracking down the man behind the scenes, Shen Lingyi repaired the damaged water transport lines, using his father's old contacts and his unique skills in settling accounts to make a success of everything. But she didn't expect that her biggest opponent would be the commander of the Imperial Guard with whom she was engaged. He was ordered to investigate the case thoroughly, but he stopped her at every turn, as if he was protecting someone. When the secret of the exquisite dice was revealed, she realized that the water transport crisis was just a move in the court's chess game.
