Hello fellow shelter residents, I am Lin Feng, the supervisor of shelter 414. I have good news and bad news to tell you. The good news is that the war is over, the shelter has successfully played its due role, and now we have to return to the surface and rebuild civilization from the ruins. It is now the 233rd year after the end of the world. The entire world has been completely destroyed in the war. Civilization has retreated like a collapsed tower. Zombies, insect swarms, and various mutated creatures are rampant in the wasteland. Our task is to rebuild civilization in the wasteland and continue what our predecessors have left unfinished. "
