The Superb Treasure-Hunting Team

Many people went to both sides of the Netherworld River every day to dig up and gather materials that had been washed ashore. For the past hundred years, these people came from the side branches of various Factions, or outer Factions that weren't significant. Since they were weaker, they were less affected by the laws of the Netherworld River. They could withstand the corrosion of the Netherworld River for a longer period. The Netherworld River had a greater influence on the souls of those who were stronger. For example, those with unusually good hearing would find certain sounds unbearable as if they were being subjected to hell, while the weaker ones who couldn't hear them would feel at ease.
