As the game's notification chime rang out, a celebratory interface with a purple-and-gold border and subtly shifting textures popped up. Su Mo's expression turned incredibly peculiar.
As a veteran disaster-relief survivor standing at the very forefront of humanity, this was only his second time seeing such a thing.
Tracing back to the first time would mean turning the clock back two entire months to the day before the novice acid rain disaster struck.
Back then, the Underground Shelter had upgraded to stone and acquired a complete drainage system, earning the game's recognition that his chances of surviving the disaster exceeded 99 percent. Since then, whether through the subsequent Blizzard, the welfare disasters, or even the descent of the wasteland ocean, this notification chime seemed to have vanished completely. It had never rung again.
