Jie Yuchen sent a page of old accounts, but Wu Xie only saw one mistake: in the records of the Zhang family's ancient building entering the mountain, a sealed transport team transported an extra coffin.
After matching the date, expense, paper fibers and tracks, he discovered that it was not a clerical error, but "No. 13" That had been erased from the account. What's even more strange is that the coffin was returned and the person who took it over had no name, only a black copper seal that did not belong to the Zhang family tree.
Wu Xie pursues the debt, and Fatty Wang is responsible for holding him back; Zhang Qiling recognizes the old mark, but only confirms the danger and does not claim responsibility for anyone; Jie Yuchen holds the missing pages of the old Jie family's handicap, but does not give the bottom; Black Blind Man appears with another commission, and the thing he is looking for is also on this return line.
From Wushanju on a rainy night to the old southwest mining road, from node 317 to the underground station outside the map, the five people moved along the transportation line that had been dead for many years, only to find that the rules were still waiting for someone to enforce them. Someone collected the account pages, someone opened the door for the unknown person, and the coffin also placed the old accounts of the five people in front of them.
When the thirteenth space is opened, there is no body in the coffin, only a set of witnesses that can hand over "identity" and "responsibility". Will Zhang Qiling become the keeper? Does Wu Xie dare to make this account public? What they have to face in the end is not what is in the ancient building, but who is qualified to live for whom.
