Facing a beast wave attack formed by king-level demon beasts, the grandmasters could still manage to resist it with the help of the city. However, it was different when their opponents were overlord-level demon beasts. They were terrifying existences comparable to a nuclear bomb.
Commander Zhao's body trembled, but he forced himself to calm down. He immediately ordered into his ear-mic, "Quickly sound the city's special alarm. All residents of the city are to be transferred to the underground!"
"Order! Anyone who has reached the level of a martial artist and above, quickly head to the various defense lines in ten minutes and prepare to resist the beast wave attack!"
As soon as he finished speaking, an ear-piercing alarm instantly sounded throughout the entire city.
Di. Di. Di. Di. Di.
The calmness of the city was instantly gone due to the emergency alarms.
"What happened?"
"There are actually five alarms going off at once!"
