However, during this annual event, any good things in the outskirts are bound to be plundered. The fabulous opportunities in the hinterland become even more alluring. Moreover, it's not humans but the monsters from the Hundred-Thousand-Mountain who are the closest to the thunder marsh. The Central Valley dojo is on strict guard, specifically to prevent monsters from launching sneak attacks from the thunder marsh.
Therefore, each time one enters the thunder marsh, cultivators and monsters inevitably engage in a bloodbath over the precious treasures, leading to corpses strewn everywhere and blood filling the water. Of course, more often than not, it's a case of one's own people backstabbing each other. Hence, those who come in search of fortune might not just be after the spiritual materials that grow in the marsh — the loot from the slaughter and plunder can be enough to make a killing.
