Immortal Dao Killing Formation City

"The data for formation node 17,237 is as follows... Our department believes..."

Ou Yanghui and the others were racing to calculate the operational data and formation nodes of the Ten-Thousand Immortal Mountains Water Realm Formation, drawing on technical support from the Immortal Gate Academy of Sciences to find a flaw.

They cracked one problem after another. At most, they estimated, it would take another month to break this entirely new formation.

That speed was already astonishing.

The formation embodied the concentrated wisdom of the Black Tortoise Heavenly Palace's formation masters. It contained countless misleading, bewildering structures, more complex than those of nearly any other fifth-tier formation. One careless step could lead a person in circles—or into a far more terrifying trap.

If this formation were released across the star region, no fifth-tier Spirit Transformation formation master working alone could break it in less than several decades. It was simply too difficult.

"...Our department believes..."

"...believes..."

Ou Yanghui's voice cut off as if someone had seized a duck by the neck. Her eyes went round.

What had she seen?

This formation had consumed untold effort from the Black Tortoise Heavenly Palace's Spirit Transformation formation masters. Its traps were virtually endless—enough to keep every formation master in an entire minor world from fully unraveling it in their lifetimes.

And just like that, it crumbled to ash before her eyes.

With a single sword strike!

"How could..."

Ou Yanghui murmured as though dreaming.

Was this how the Great Sun Sword Pavilion, once ruler of the realm, had broken formations?

Stunned as she was, she issued the command by instinct.

"Fire!"

The staff officers shouted.

The Ten Thousand Immortal Mountains turned to ash!

Great Sun's radiance shone over millions of cultivators. Nothing stood in the way of the Immortal Sect's forty-eight army-group naval guns
