This was a brilliant "Light Burst."
An arc equivalent to one-quarter of a Sun Rune Ring disintegrated in the sky, then transformed into several larger glowing structures. For a short initial period, they still ascended and moved across the sky according to the normal trajectory of vision 001, as if each glowing structure still possessed residual power and navigational functionality, but in just a moment, their movement displayed clear signs of being out of control.
The glowing structures began to shatter into pieces, large and small luminous bodies scattered like fleets torn apart in a storm, carving bright, gradually distancing lines across the sky, and from these larger bodies split many smaller sources of light—compared to the large fragments, they were as inconspicuous as fireflies, falling from the sky with twinkles and a series of small explosions.
