A sharp and ear-piercing air-raid alarm suddenly sounded above Quicksand Town.
It was so loud that it almost enveloped the entire town!
Chu Lingjun and the others, who were originally in class, looked out the window nervously.
Although everyone was shocked, they did not panic.
After all, the air raid siren sounded a few times a year!
After the initial shock, everyone began to focus on listening to the alarm outside the window and looking at the tower standing in the square in the center of the town.
However, when they saw the red pillar of light on the tower and the air-raid siren that sounded three times longer and one time shorter, the panic on everyone's faces immediately increased!
"Three long alarms and one short alarm. This is a level one alert!"
"Is it a beast tide?"
"The scale of this beast tide is probably huge!"
Chu Lingjun's heart sank.
A level one alert was the highest alert!
