When one dropped coins down in this magical place, it could summon a treasure, immortal weapon, or even a divine beast. Of course, being unlucky would probably mean death. Not only would they lose their coins for nothing, but the summoned danger could also end their lives.
Nevertheless, the appearance of this area brought about excitement each time and people came in droves. Opportunities and danger were together here; so many became rich overnight while many lost their lives.
