The earthquake that struck the hearts of many upper-class citizens in Apali City lingered with aftershocks long after the event.
The Iron Fist Gang, Golden Lion Group, Ghost Team, and Shadow Alliance, these four behemoths that had dominated the Underground of Apali City for ages, entangled with countless networks of human connections, had all been annihilated in a single day.
