Trap

 The sound of a door opening echoed in the middle of the night, and while the officials and the people were celebrating their new-found freedom, someone crept inside the cleaning department of the city. 

Soon the person stepped inside the control room and kicked the woman who was lying on the floor. 

"Looks like the dose was just right." When the thug saw that the woman in charge was not waking up, she heaved a sigh of relief. Fortunately, she brought the right thing with her.

The thug tiptoed around the control room and then walked over to the system that controlled the drones that cleaned the city. 

A snicker left her lips, and she immediately pushed the button to turn the cleaning system before blasting it to the maximum power. 

Let's see how they would like this. 

On the other side, in the city, no one was prepared for the scheme that had been set and prepared by Yu Xinyi.
