Inheriting the late-night reading room of the century-old library, I hold the fatal twelve borrowing rules in my hand and take charge of the Yin-Yang Ferry! The natural yin and yang eyes can see the obsession of the dead souls, and strictly observing the rules is the only way to survive! The museum opens on time at midnight to save lonely souls, and locks the door on time in the early morning to hide the truth. Those who break the precept will never survive!
The old museum of the Republic of China in Jiangcheng has hidden secrets for hundreds of years. The twelve rules are taboos that were exchanged for blood by the predecessors. Any disobedience will lead to disaster. Liu Feifei, who just graduated, followed her ancestors' last wish and took over this strange job, giving up her stable future and sticking to the iron law.
She does not accept gifts from dead souls, does not inquire after a moment, does not borrow black-covered books, and abides by the rules to redeem the dead souls who are lingering with regrets, and helps the wronged souls to clear up their grievances.
At the same time, all the clues of the dead souls point to the secret case of the Liu family that has been sealed for decades. She secretly cooperates with the police to unravel a series of long-standing unsolved cases in Jiangcheng. With a mortal body, she saves the house, crosses the dust and uncovers centuries-old injustices!
