Boom!
A peal of thunder exploded in the sky, and silver-white lightning flashed across the heavens.
A sudden thunderstorm descended upon a certain area of Black Mist Marsh.
However, due to the obstruction of the black fog, even if people and Demon Beasts from afar heard the rumbling thunder or caught glimpses of the silver-white electric light, they couldn't see clearly what was actually happening there.
Moreover, this was just a thunderstorm; even Mortals would experience many such weathers in their lifetimes. Why would it attract anyone's attention?
Those who held this thought were doomed to miss an incredibly rare sight of a spectacle that comes once in a millennium.
Among the dark clouds and lightning, a giant One-Horned python covered in silver-white scales wound upward towards the sky, confronting the descending thunder and lightning as if a dragon endeavored to ascend to heaven.
It flew not swiftly, as if there was a great resistance above.
