Viewed from above, the post-disaster world not only lacked any sense of apocalypse, but its natural environment was even much better than before. Vast grasslands spread out like green carpets, while oxbow lakes divided them like doughnuts.
Near this oxbow lake stood a mobile fortress. Its metal tentacles, each nearly ten meters thick in diameter, curved beneath it, their clawed tips stabbing into the ground and securing the entire fortress in place. Even a typhoon of level twelve or higher would not be enough to budge it. The fortress's outer armor gave off an inexplicable sense of security.
This mobile fortress was called Fortress T5·619. Because of the cruel methods of its leader, Li Siniwei, outsiders called it the Doomsday Fortress. Of the living creatures that entered this place, few besides the Beast Clan could come out alive.
The Doomsday Fortress was a fifth-grade fortress, one of the smaller fortresses among the six tiers from T0 to T5. The fourth- to first-grade fortresses above it grew larger as their numbers decreased, and naturally housed larger populations.
Besides the fifth- to first-grade fortresses, there was one more level above them: the Undefeated Fortresses, more commonly called the Immobile Fortresses. There were only three, and all belonged to the Beast Clan.
These three Immobile Fortresses truly did not move much. They remained deployed year-round, and in people's minds, they were more like fortress cities.
The three fortress cities represented the three strongest factions of the Beast Clan: the radical, the conservative, and the neutral. These were the distinct styles of the Beast Clan's three major factions, and the T5-grade fortress—the Doomsday Fortress—was one of the supporters of the radical faction.
