My name is Chen Chen, and I am a corpse collector. People in the industry call me "Shui Drill". When the upright corpse in the ditch stared at me with its eyes open, I thought it was just an ordinary evil. Until the bronze waist badge left by the missing master suddenly became hot, burning away the invisible ghost under the water. Until I dug out the bronze medal with the same runes engraved on it from the corpse mud. Bronze fragments, I realized that the master's disappearance was unintentional. Every time I dived into the Dead Man's Trench, the sunken ancient village, and the Yuan tribe's tomb, I was getting closer to a forgotten truth. The yin and yang were becoming unbalanced, and the gate of the abyss was about to open. And my hands, which were used to fishing for corpses, were holding the waist badge that was getting hotter and hotter. Either calm this turbulent wave, or... Sink with this world.
