Doomsday Escape: My Progress Bar Can Be Upgraded

This is a huge migratory convoy, like a scarred steel python, crawling hard on the desolate and dilapidated wasteland. In front and behind the convoy, some figures could be seen vaguely exuding an aura that was far beyond ordinary people. They either scanned the surroundings with eyes like lightning, or they were carrying strange weapons, with a faint light flowing around them - they were "sequence powerhouses", human beings awakened after the cataclysm and were able to fight against twisted monsters and strange environments.
