Several True Immortals applied the Bloodline Tracing Method, but failed to find anyone related to Zhao Tingxian by blood in the Cangyun Realm.
The disappearance of the Zhao Clan descendants undoubtedly caught many by surprise.
In order to avoid oversights, several True Immortals retraced Zhao Tingxian's cultivation path, starting from Tai Xu Holy Land, and soon located the Great Zhou Dynasty.
The Great Zhou Dynasty was just over three hundred thousand miles from Giant Marsh, and had been affected at the outbreak of evil energy, now already within the scope of its envelopment.
Ordinary humans cloaked in evil energy were not as severely affected like the cultivators; they just encountered more epidemics. A considerable number of these humans, after being eroded by evil energy, became physically stronger and gradually more violent, losing their ability to communicate, and began to undergo "demonization."
