Ancient Celestial Sixty-Eight World Groups.
Blue Thunder Civilization.
As suggested by the word "thunder" in its name, this is a peculiar world filled with thunder.
Of course, just like the Canglan Star's descent into the Primordial World brought frequent disasters, thunder only appeared in the Blue Thunder World after entering the Age of Calamity.
In the history books of the Blue Thunder People, the first day of descent is called—the Disaster of Heavenly Thunder.
According to records, on this day, more than ninety percent of the world's regions experienced large-scale overcast weather.
Just a few hours later, extremely frequent lightning phenomena occurred in various places in the Blue Thunder World.
Most mysteriously, every bolt of lightning that struck was blue.
Ordinary lightning, if it doesn't strike directly onto a person, usually doesn't kill.
But blue lightning is different.
