At the sound of the alarm, the expressions of every member of the Sea-Breaking Team changed in an instant.
Because they were about to enter the core area, they had all significantly raised the alarm threshold on their Mechas' Zombie Detectors.
The Zombie Detectors wouldn't even react to ordinary Mutated Zombies, or even the appearance of a Third Level Mutated Zombie.
Only upon detecting a Fourth Level Mutated Zombie would they emit that piercing alarm.
And any Fourth Level Mutated Zombie was a cause for concern. Almost simultaneously, everyone immediately looked at their Zombie Detectors.
If the alarm had merely made their faces shift, one look at the detectors made many turn pale instantly, their eyes filled with terror.
According to the Zombie Detectors, Fourth Level Mutated Zombies were rapidly approaching from underground. It wasn't just one or two, but thirty of them.
