These chakra masses were different from the natureless chakra he had originally bestowed.
After spending several years inside the guards, they had gradually taken on each guard's chakra nature. Drawing on these nature-infused masses, Zou Hyuga vaguely sensed that he could perform ninjutsu.
If he could use ninjutsu, he would be able to handle Kakuzu without entering Sage Mode.
In the past, he had entered Sage Mode to disrupt his enemies' ninjutsu with violent natural energy, then defeated them with his extensive taijutsu experience. The Tailed Beast Bomb was far too conspicuous, so he rarely used it.
Pulling his wandering thoughts back, he found that Kakuzu's ninjutsu bombardment was still ongoing. Dazzling techniques flashed through the woodland. With Earth Grudge Fear, Kakuzu had at least several times the chakra of an ordinary Jonin.
Even after unleashing more than a dozen techniques, he showed no signs of running out of chakra.
In a flash, Zou Hyuga appeared opposite Kakuzu. His hand seals were not particularly fast, and he took several seconds to complete the technique before calling in a low voice, "Fire Release: Great Fireball Technique!"
In an instant, scorching heat coalesced into a tiny sun rising through the night sky.
Zou Hyuga's Great Fireball was several meters in diameter. Merely flying toward Kakuzu, it sent sparks rising from the trees along its path, setting them ablaze with crackling flames.
Kakuzu's expression changed at once. He hurriedly controlled his masks and formed hand seals. "Water Release: Water Formation Wall!"
A wall of water rose from the ground in front of Kakuzu, canceling out the Great Fireball and sending steam billowing into the sky. The vapor filled the entire forest, on a scale no smaller than the earlier Hidden Mist Killing Technique.
This Fire Release burns my mouth a little... Zou Hyuga
