Three days later.
It was another busy day for Beijing, China's capital city. The sun was shining ever so brightly, but air pollution was still so thick within the city. Almost everyone was wearing masks as they walked towards their destination.
Suddenly, everyone saw a thick cloud of black smoke approaching the city. They were surprised and thought that heavy rain was about to fall, but when it went nearer, the people realized that it wasn't actually a cloud.
It was several hundred circular drones with what looked to be guns attached on their wings. They looked like a thick cloud of black smoke from afar, but they were actually aerial beasts flying arrogantly in broad daylight.
Everyone became wary of the sudden visit of those drones. They knew that it was not just a simple tour based on the atmosphere it released. How could that amount of drones not have some sort of plans especially after seeing the weapons attached to their bodies?
