This sudden accident and disaster had indeed caused considerable trouble for everyone in the Star-Level Shelter.
Fortunately, it was ultimately confirmed to have been nothing more than a False Alarm.

In addition, Li Chen had also greatly upgraded and reinforced its other defensive Firepower Systems.
Better safe than sorry.
He was now suffering from a kind of "Firepower Insufficiency Syndrome." Everything for his shelter had to be the best and strongest available!
