Within this ancient, barbaric great world.
Though it was rather dark, being inside it made one feel incredibly small.
Yet it was far from quiet.
Animals passed by from time to time.
Had the middle-aged man not mentioned it beforehand, the group would surely have mistaken this place for a real world.
"Remarkable," Xu Zimo sighed.
"I possess a single formation heart, evolving heaven, earth, and all things."
"Everyone, this is a killing formation," the middle-aged man's voice came from all directions.
The next moment, a murderous aura suddenly filled the world.
The animals from before seemed to mutate one after another.
Their bodies swelled to a hundred times their original size. Whether on land or in the sky, all manner of beasts and birds gathered together.
Like the scene of a Ten Thousand Beasts Stampede, they charged toward the three of them.
"Good!" Purple Cloud Sage gave a light shout.
Purple clouds erupted all around him.
But in the next moment, he frowned slightly.
"My laws have been suppressed. There is actually such a formation here."
He could clearly feel that his laws did not operate as smoothly as they did outside.
"Focus on sensing this world. Killing these demonic beasts is secondary," Xu Zimo replied.
"Perhaps you may gain some insight from it as well."
Moonlight Fairy and the other nodded.
Xu Zimo did not use Overlord Shadow. He watched the demonic beast charging straight at him.
He directly grabbed the beast by the neck and lifted it up. Then, ignoring its roars, he crushed its neck.
After the demonic beast died, there was neither blood nor corpse. Instead, it transformed into streams of formation laws.
Xu Zimo carefully sensed them for a while.
Then he shook his head and muttered, "Though mysterious, it ultimately has no life."
