So-called prehistoric ruins were, for the most part, tombs of ancient gods. During the ancient era of the other world, even ancient gods below the Main God Tier could die.
After their vitality and blood declined, those at the peak of the High God rank would seek out a safe place to find a way to break through, while those below the High God rank would find an undisturbed area to bury themselves, preventing their enemies from turning them into war puppets.
No matter which kind they were, their tombs generally contained abundant treasures, such as the armor and weapons they had used. These items were indestructible, but the tombs also came with dangers.
One danger was the protective restrictions the tomb owners had set up for themselves. If they were not broken, anyone who entered rashly would be attacked by the restrictions. The power of those attacks was often comparable to the tomb owner's strength, only less flexible.
Another danger was the tremendous resentment produced when the tomb owner failed to advance to the High God rank. After accumulating for more than a thousand years, that resentment turned into this green mist. In truth, the mist was filled with bizarre insects.
These insects were born from the corpses of ancient gods. They had no consciousness and merely inherited the ancient gods' hatred. They would devour any living creature they encountered; even Low Gods could not withstand their erosion.
Lu Yang watched as the green mist drifted to the mouth of the cave and flew toward the ground. In an instant, countless Dark Demons and Blade Demons roared in panic.
"The green mist is here again! Get out of the way~!"
"Don't let it touch you! Run!"
"Activate the teleportation array and send it away!"
