Black Sea.
Within the vast expanse of the Black Sea's space.
A solitary, pale white sphere named Blind Spot ominously emitted an inauspicious black smoke.
The black smoke enveloped and segregated the sphere, forming a natural shielding and hiding buffer zone.
From the outside, it appeared to be an inconspicuous, Common little Blind Spot, without any oddity.
But at this very moment, a faint and peculiar fluctuation was penetrating from within the sphere, spreading outwards.
As soon as this tiny fluctuation entered the Black Sea, it suddenly dispersed, transforming into a vast spider-web-like expanse, scattering in all directions.
The speed of the spider web's vibrations far exceeded that of light. In the blink of an eye, it traversed tens of millions of kilometers, continuing dozens, hundreds, thousands of times, with the rate of its pulsations growing ever faster.
Before long, a light-year had passed.
And when its speed suddenly crossed a certain special threshold.
