Echo in the Wasteland Su Xingchen squatted under the eaves of an abandoned gas station, rainwater dripping down the holed iron sheet and hitting the puddle in front of her. The air was filled with the smell of rust and decay. This was the most common smell in the wasteland, and she had long been used to it. Are you sure this is here? A muffled voice came from behind. The speaker was Ouyang Ruiyun, the leader of their team, a man in his early thirties with a stubble on his face. He was holding a modified shotgun in his hand, with a cloth strip wrapped around the barrel to prevent reflection from exposing its position. Su Xingchen didn't look back, just nodded. Three days ago, when they were searching for supplies in the old city thirty kilometers north, they found a hand-drawn map. The paper was yellowed and had burnt edges, but the route was clearly drawn, leading to the basement of this abandoned gas station. Written on the back of the map is a line of text: Here is what you need. Who painted it? Why paint? No one knows. But everyone who has survived in the wasteland knows one thing: no clue can be missed. Food, water, medicine, weapons, these things will not come to your door by themselves. There is movement. Ouyang Ruiyun suddenly lowered his voice. Su Xingchen held his breath.
