Night, 21:44.
The provincial capital of Fengnan Province, Nanzhou.
Boom!!
A deafening blast exploded at the city's tallest signal tower.
Orange-yellow flames shot into the sky, accompanied by billowing smoke, drifting with the wind.
The moonlight of the night was also temporarily obscured by smoke and firelight.
The alarm sounded rapidly, and one after another, the flying cars from the surrounding security branches lit up, converging towards the direction of the signal tower.
Invisible waves swept over from above the signal tower at high speed, as if scanning for something.
Crowds and vehicles below the tower hurriedly fled, and the ring-shaped blocks were emptied in just over ten minutes.
Then came several black and white police cars, with flashing red and blue lights speeding towards the scene and stopping.
From one of the police cars, the door opened, and several stern figures with silver briefcases disembarked.
