Only a corner of the Immortal Slaying Formation unfolded, yet the Nine-River Celestial Chart moved on its own
Four sword silhouettes hovered between heaven and earth.
At their center, a formation diagram gently unfurled.
Tongtian had naturally neither summoned the true Four Immortal-Slaying Swords nor laid out the complete Immortal Slaying Formation in the Three Immortals World.
What he manifested now was only a small portion of its Great Dao structure.
But for Yunxiao.
It was enough.
The Immortal Slaying Formation was one of the greatest killing formations in the Great Wilderness.
Its true mysteries far exceeded what she could fully comprehend at her current level.
Nor did Yunxiao need to see how powerful the entire formation was.
She only wanted to know.
What exactly Tongtian had meant by "letting the formation execute its functions on its own."
The moment the four sword silhouettes appeared.
Yunxiao immersed her entire attention in them.
The first sword silhouette stood in the east.
Its killing power was the strongest.
The second stood in the west.
Its sharpness carried an unmistakable intent of annihilation.
The other two were likewise distinct.
Viewed individually, the sword silhouettes even displayed clear differences in their Great Daos.
But once the central formation diagram unfolded.
Everything changed.
Like an enormous core, the diagram incorporated all four sword silhouettes into a single whole.
When the first sword suffered an impact.
Tongtian did not need to actively direct that pressure at all.
The Great Dao markings on the formation diagram glowed faintly.
Some of the force flowed into the other three positions on its own.
When the sword qi at one position weakened.
The other positions automatically replenished it according to the formation's rules.
Once an outside aura entered a certain range.
The four sword silhouettes even adjusted the direction of their killing strikes on their own, according to distance, threat, and changes in the formation.
Yunxiao's eyes grew
