This area belongs to the Tianhe Flood Zone, therefore the Earth Immortal Realm calls it the Dao Contaminated Swamp Zone.
There is a Green Stele within the Dao Ruins that suppresses it, making it less dangerous. However, the surrounding Dao Contaminated Swamp Zone is the most perilous place.
Back then, when the Heavenly Court gave Chen Shi the Dao Ruins, it was akin to drawing a prison where Chen Shi couldn't move freely, trapping him in this place. If Chen Shi wanted to escape from the Dao Ruins, he would only find himself turned into a caged bird, trapped within the Dao Ruins with no escape.
