The following events occurred within one hundredth of a second.
Nuclear explosion.
The Black Hand Master pulled the trigger.
A pre-buried metal aerosol smoke screen exploded around.
In the high sky, a mass of pure light rapidly expanded. Its might may be insignificant compared to the sun, but its distance from the ground is even more negligible compared to "one astronomical unit." The light sphere almost instantly surpassed the sun and continued to expand recklessly high in the sky.
At this moment, the Black Hand Master had already disconnected the cable from the electromagnetic sniper rifle. The cooling module ejected within two seconds. The Black Hand Master threw it onto a drone without a care. Under thermal imaging, this thing was blindingly bright, a burden in a breakout battle. The cooling module would release nearly exploding coolant at the end of the countdown, perhaps attracting some enemy attention.
