Three years ago, the sky suddenly materialized and began to fall, forming a devastating "cavitational rain". These sky debris have weird properties that change the laws of physics, continue to threaten human survival, and are also reshaping the earth's ecosystem.
The technical elite fled to high altitudes to build cloud nests, ordinary people formed tribes of scavengers on the ground, and religious fanatics formed the Tianyuan Sect.
When the first piece of the sky fell, people thought it was a particularly bright meteor.
Until it penetrated the Tokyo Tower but did not explode, but twisted the three-hundred-meter-high steel structure into a spiral metal bouquet; until a hexagonal crack with a diameter of two kilometers appeared over Chicago, revealing the blue "inner sky" with non-Euclidean geometry behind; until all the weather satellites in the world returned the same set of strange data - the atmosphere is acquiring the physical properties of solid matter.
Three hours later, the sky shattered.
Sinking blue
It's the temperature of the sky breaking in my arms
And all the declarations of the day
They all became suicide notes when they fell
