long night fire

Everyone on the dust believes that there is a way to a new world buried deep in a ruin amidst danger and famine. As long as you can find a unique key and open that door, you can enter the new world.
There, the earth is fertile, like milk and honey flowing, and the sun is shining brightly, as if it can wash away the cold and gloom.People no longer have to face barrenness, monsters, infection, distortion and all kinds of dangerous things.
There, children are happy, adults are happy, and everything is beautiful.
Every antiquarian, relic hunter, and historical researcher on the dust knows that this is the new world.
