Night House Restorer

There is an old saying in the old town of Huichuan: Don't open the third door at night. For three generations, Chen Yan has been a home renovator, specializing in jobs that others dare not touch - haunted houses, deserted houses, and unfinished buildings. Some people say that he repairs beam doors and windows, but only he knows that it is never the house that is really broken, but the people's hearts hidden in the walls. One spring rainy night, he received a high-priced commission: the Gu family's old house, which had been closed for 19 years, had to be repaired within seven days. The client only made one request - the third door in the west wing must not be opened. But on the first night after entering the house, the sound of wood planing came from behind the wall. The next day, he found the mark left by his father before he disappeared on the inside of the beam: a nail driven upside down. Nineteen years ago, seven families in Huichuan closed their doors on the same day, and seven children disappeared overnight. Everyone said that Chen Yan's father was the final murderer. No one believed him. But Chen Yan didn't believe it. He took his chisel and took apart the first wall. There are no ghosts behind the wall, only a skeleton that has been hidden for nineteen years, a last letter written by his father, and a piece of truth sealed by someone's own hands. A back nail, a mark. He searched for nineteen years, demolished seven houses, uncovered seven lies, found seven children, found his father, and found his innocence.
