Embers Ad Infinitum

Everyone on the earth believes that buried deep in a certain ruin in danger and famine, there is a way to a new world. 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, the sun is shining, and it seems to wash away the cold and gloom. People no longer have to face barrenness, monsters, infections, distortions and all kinds of dangerous things.　　 There, children are happy, adults are happy, and everything is beautiful.　　 Every antiquities scholar, relic hunter and historical researcher on the dust knows that this is the new world.
