Talking was pointless.
Practice was the only path to truth.
Just how tough this [Karma-Type Domain] was, they would only know after testing it.
The next second.
From over ten thousand meters away, Natsume raised a hand.
The semi-divine artifact [Pseudo-Heavenly Marsh Spear] floating at his side shot forth, sending ripples through space as it streaked like a beam of light.
It struck the city wall almost instantly.
A massive explosion erupted.
The extreme heat and blinding light melted the surrounding land like butter before vaporizing it.
Its power far exceeded that of any [Giant Truth-Seeking Orb].
Had it fallen on the [Ninja World], that tiny little planet would probably have exploded already.
However.
This probing attack achieved nothing.
At the point of impact, the barrier merely rippled in a ring. Before the wave could spread several thousand meters, it was smoothed away.
Against the enormous barrier spanning over ten thousand square kilometers.
It was like poking a cannonball with a toothpick.
Or, more accurately, like stabbing a rubber ball with a steel needle.
The steel needle was hard enough to pierce it.
But the "rubber ball" was so elastic that it could disperse the force completely, making it impossible to puncture.
Even an attack powerful enough to destroy a planet.
Would be weakened to an absurd degree when spread across ten million Otsutsuki.
Not to mention that these ten million elites of the Otsutsuki Royal Family were all, at the very least, at the Six Paths level—monsters who had absorbed the energy of an entire planet.
Their vitality was already incredibly strong, and they were tough as hell.
"It really is hard."
Natsume reached a conclusion at once.
The [Pseudo-Heavenly Marsh Spear] was already a top-tier semi-divine artifact. Even ordinary demigods could not withstand a single blow from it.
