On the twenty-third of the twelfth lunar month, Zong Yu returned to the county town he had not returned to for several years.
His old friend Cheng Chuan suddenly found him and asked him only one sentence:
"Do you remember the hole we found under the old bridge when you were a kid?"
They thought it was just a memory from their childhood.
But as the investigation begins, an old road that has disappeared, a project record that has been sealed for many years, a group of people gradually disappearing from the archives, and those warnings about "do not continue" slowly begin to point to the same place.
They discovered that some things in the county were not torn down.
It's just hidden away.
And those who disappear from the surface may not really have left this world.
Starting from an old bridge, Zong Yu, Cheng Chuan, Lin Lu and Fatty followed the traces buried by time all the way down.
They originally just wanted to know what was under the bridge.
Only later did they discover that what they were really facing was a civilization that had coexisted with the surface world for a long time but had never been recognized.
There are people living where we can see them.
There are also people who have been living in places we thought did not exist.
If one day you find that the place where you live is just "outside the house", will you still be willing to go back?
Concept: We think we own the world, perhaps just because we have never seen the other side of the world.
