Lin Feng found an old photo in his old house. His grandfather and the three of them were standing in front of an ancient well. On the back were words written in blood: "I killed the third one. Guess who is the third one?"
Uncle Chen said that his grandfather was greedy and pushed his companion down the well. Paralyzed Uncle Wang wrote: "Uncle Chen lied to you."
Exploring the ancient well at night, there was a note next to the bones: "When you hear the third footsteps, it's your turn." Uncle Wang appeared: "We pushed your grandfather, but he didn't die. He climbed up and killed us all."
The phone vibrated: "Kid, thank you for bringing him out. Look behind you."
At the attic window, a figure in shroud raised his hand. Sender - late grandfather.
Intention: Every generation thinks that they can climb out of the well of their ancestors, but they don't know that the well has been waiting for them to carve their names on it.
