Five nights later, Mirai let out a sigh of relief. Holding three sealing scrolls in his hands, he grinned from ear to ear.
"This young master is no longer a man! This time, I'll let you enjoy yourself to the fullest!" Mirai's eyes glittered, and a strange smile hung on his lips.
The three sealing scrolls contained three rounds of Killing Ash Bones and Spears.
Bone spears would pierce through everything within a hundred-meter radius, creating a vacuum within that same range.
Sealing scrolls had both advantages and drawbacks. Their advantage was that, in theory, a ninja could store techniques indefinitely. They could be released in battle without consuming a large amount of chakra.
Their drawback was equally obvious: sealing scrolls were far too inconvenient.
Moreover, aside from those capable of killing at any level—such as Mirai, with his chakra reserves—sealing scrolls were practically useless to everyone else.
With insufficient chakra reserves, the damage they could inflict was imaginable. Even if some chakra had been stored beforehand, its power would not be great.
Those with sufficient chakra reserves and offensive power had their own casting speed for sealing scrolls.
