Nine people entered the burial mountain.
Seven days later, only one came back.
He was not seriously injured, but he did not recognize his wife and forgot who he was.
The rescuer asked him: "Is there anyone alive down there?"
He looked at the roof of the tent and said only one sentence:
"The living have come out."
"The rest down there are waiting to be buried."
In order to find the missing rescue captain Han Zhiyuan, cave explorer Zhou Yan led five team members into the mountain through an old mine tunnel that had been sealed for 21 years.
Old shoes placed facing inward at the door, bones moving along fixed routes, living people who regard the tomb as home and refuse to leave...
The deeper they went, the more they discovered that this was not an ordinary ancient tomb, but an underground burial system that is still in operation today.
Until Zhou Yan found the geological hammer his father used in front of the Jinling Cave.
The date on the hammer's handle was actually nine years later than his father's disappearance.
In the burial mountains, the dead are all looking for their way home.
But whoever shows them the way may never be able to tell the difference again——
Where is the human world.
