The Sound of Rain Breaking on Eaves

[Tibetan in the year of Yin, granted in the year of Si, now in the year of Shen] Jiang Renyin returned to Qingxi Lane to hold a funeral for his ancestral home, "Tinglan Pavilion". The developer wants to inject water and build a well, and the old street will become a vast ocean, but Chen Mo, a retired detective, told him: It is your turn to pay back the debt left by your grandfather. The red pen secret passage under the land deed, the moss marks at the wellhead, and the camphor wood box that must be picked up before flooding... The "living deed" in the box does not sign for profit, but only for human life. When the turbid river water reached his ankles, Jiang Renyin discovered that he was not only the digger, but also the last dead chess piece in this 60-year series. The water overflows the golden mountain, who is in the urn?
