The time span, that is, was different from the passage of time in the Physical World.
In the initial years following the outbreak of the Calamity, there was a significant time span within the Disaster Fog.
Those humans swallowed by the Disaster Fog first had spent a considerably long time within.
Among them, some had ascended to strength and fought against the Catastrophe Fog Master.
Some lost, and the Disaster Fog successfully transformed into the Forbidden Zone, like the Great Snow Mountain in the Heavenly Kingdom. That was the final battlefield where humans resisted the Disaster Fog.
Some won, slew the Catastrophe Fog Master, and brought their human compatriots back to the Physical World. For instance, the Old Mad King—many powerful humans had successively made sacrifices to buy him time for development.
After that, the time span gradually disappeared.
