The Eternal Dark Abyss knows no distinction between day and night, perpetually enshrouded in darkness—only within the cities of the major sects does light exist.
Due to the special circumstances of the Eternal Dark Abyss, as long as the black tides on the surface do not recede, Dark Spirits, those discordant beings, could appear at any time and place.
In such circumstances, even a powerful sect like the Spiritual Leaf Sect cannot afford to cleanse the land with Battle Spirit Plants every day, especially since those disgusting Dark Spirits can also drop some extremely useful Yin attribute materials.
Entry into the Eternal Dark Abyss is not just a casual affair; although the major sects have set up Teleportation Arrays everywhere in the Cultivation World, getting in requires spending Spirit Stones.
Apart from those wealthy Cultivators from large sects who want to kill monsters for training and exploration, other Cultivators need to support their fights with more fights.
