Even Shihōin Naraku's super sensory ability could still improve, showing just how formidable the Mind's Eye of the Kagura truly was.
That alone left Naraku very satisfied with this reward.
At his level, improving his sensory ability had already become extremely difficult. Only a massive surge in his own strength could potentially bring it further along.
Yet the system's reward had given him this rare opportunity.
This was also why Naraku had always placed such importance on the system.
The rewards obtained from its draws could break through the limits of strength.
For other ninja, limits they were destined never to break were like impassable chasms. Naraku was different. With the system's help, he could disregard these chasms that hindered his progress.
Feeling his sensory ability improve, Naraku nodded in satisfaction. "Let me see the remaining rewards..."
"One-thousandth of the Nine-Tails' chakra!"
This reward was still no surprise. When Naraku began the ten-pull, he had already sensed that he would draw the remaining Nine-Tails chakra.
"That means I've gathered the chakra of all nine tailed beasts inside me."
"But I don't feel any different!"
Naraku was somewhat surprised. He felt the Nine-Tails' enormous chakra surge into his body, but this reward offered only a limited improvement to his strength.
Truthfully, compared to one-thousandth of the other tailed beasts' chakra, the Nine-Tails' chakra was especially vast.
This also showed the enormous differences in chakra reserves among the nine tailed beasts.
Just like their tails, the more tails they had, the more chakra they possessed.
At the same time, Naraku received more chakra as well.
Of course, at Naraku's current level of strength, a merely enormous mass of chakra would not produce a dramatic leap in his power.
Even the Nine-Tails' chakra was no exception.
"I thought gathering one-thousandth of all nine
