While Li Changhe was tightening his defenses,
all the major Safe Zones had already faced terrible attacks from the Terror Devils.
The unofficial Safe Zones were almost instantly wiped out, with only a few personnel managing to escape.
Even among the official Safe Zones, two were completely breached by the Terror Devils.
Theoretically, the defense of the official Safe Zones was very strong. Unless those high-spec Terror Devils appeared, repelling the attacks for a month or so wasn't a problem.
There were automatic turrets and various Defensive fortifications outside, as well as artillery attacks from the external military forces and teleportation support from the Dream Cruise.
Inside, there were the players and a large number of Combat Personnel who could take the initiative to strike and kill those Terror Devils that threatened the safety of the zones.
Moreover, with the official means of identification, the Terror Devils could not infiltrate these Safe Zones.
