The universe is a huge silent tomb, and civilization is the epitaph scattered in it.
When the entropy increase of a universe reaches the limit, all laws and matter will return to death. This is called the "Return to Zero Period". However, after returning to zero, the "remains" of the universe - the "remains of the Tao" that carry the ultimate laws and civilization information of a world, will float in the sea of nothingness like dry bones.
Ye Ling is the last person to collect remains in the "Sea of Bones" where he lives. His civilization has long been "returned to zero", and his mission is to find and interpret the "echoes" of the lost world in this dead silence.
