In the shadowy woods of Blue Moon Island.
A ritual array had been laid out on the cold, damp soil beneath the moon.
This array was called the [Void-Style Boundary Technique], and it could greatly amplify the effects of techniques that interfered with space.
What did that mean? For example, if Obito used Kamui within the Void-Style Boundary Technique, its vortex would spin faster, accelerating absorption. If Might Guy unleashed Night Guy and distorted space, the resulting torque would be far stronger than if he had used it outside.
This array, which sounded useful but was generally pretty damn useless, had been personally laid out by Orochimaru with technical support from Tobirama. It had taken a month to complete.
At that moment, Danzo sat cross-legged within it, his chest and back bare. A lifelike Purple Ox-Head Totem was engraved along his spine.
The sharper readers had surely figured it out already: the array existed to help Danzo unseal the Ox-Head Heavenly King.
Unsealing the Ox-Head Heavenly King and summoning Nue would cause spatial tremors on a certain scale.
Such tremors were not enough to affect a stable region of spacetime. But if the shock waves passed through an area where stability was relatively weak, they might create localized spatial rifts.
That was exactly what had happened in his previous life. The shock waves from summoning Nue had reached the moon.
Space there had remained unstable ever since the Giant Tenseigan had been destroyed years earlier, so the tremors had cracked it open.
As a result, this planet, long protected by a barrier maintained jointly by the Three Sage Lands... had been exposed to the eyes of Momoshiki, Kinshiki, and Urashiki.
Back to the matter at hand.
Now, Sasuke intended to exploit the window-breaking effect of unsealing the Ox-Head Heavenly King
