Obito analyzed the characteristics of Kairen's resurrection ability, which was why he felt Kairen was extremely troublesome.
But Ōnoki, with mortal eyes, couldn't see anything amiss. He immediately pointed at Kairen's nose and scolded him,
"Young man, you don't play fair! You came to trick this old comrade in his seventies—do you think that's okay?"
Kairen gently exhaled a puff of smoke and said calmly, "I haven't moved a single step from beginning to end. Please don't slander me."
Ōnoki snorted. "Hmph! Under Dust Release, all are mortals. You say you didn't dodge—prove it to me!"
Kairen curled his lips, raised his hand, and said, "Alright! For the sake of being family, I'll give you another chance. Come on, continue—put on your Dust Release performance to your heart's content!"
Being erased by Dust Release only once, Kairen felt, still wasn't satisfying.
Ōnoki's face darkened. Kairen spoke so casually, clearly not taking him seriously at all.
"When I was roaming the ninja world, your dad was still drinking milk! You dare talk big to me! Watch closely… Earth Release: Fist Rock Technique!"
Ōnoki shouted. Rock-like exoskeleton appeared on his right arm. He leapt down from the sky and, with maximum momentum, launched an attack at Kairen.
The fist came down like a mountain, even more forceful than twenty years of women's punches, and smashed Kairen straight into the ground.
"Ding!"
"Ōnoki dealt 500 points of damage to you!"
Dust and smoke billowed. Ōnoki planted his hands on his hips and laughed loudly.
"Not so cocky now, are you!"
A gentle breeze passed. Kairen floated back in his original position. Aside from a bit of dust on his clothes and a few marks on his face, there was nothing else!
Ōnoki's old farmer's punch was indeed powerful, but it wasn't enough to shatter Kairen's Ōtsutsuki Sage Body.
Within two breaths, Kairen returned to perfect condition.
Ōnoki's face was filled with shock and deep confusion.
Kairen had just been smashed by his rock fist; he could even feel the impact—so why was the other party completely fine?
"Kid, you tricked me—you used genjutsu!"
Kairen shook his head and pointed at the faint marks on his face.
"Your fist is pretty hard, but my life is harder!"
"I don't believe it! Earth Release: Ultra-Added-Weight Rock Technique!"
Ōnoki, furious, used a powerful ninjutsu. This rock fist was even stronger than before.
With force that could split mountains, one punch even broke one of Kairen's bones.
"Ding!"
"Ōnoki dealt 600 points of damage to you!"
Just like before, Ōnoki's attack was heavy.
But Kairen still only suffered light injuries and recovered in the blink of an eye.
Kairen put his hands on his hips and laughed. "Ordinary physical attacks won't do! Try Dust Release!"
Ōnoki panted. Hearing Kairen's nonchalant words immediately made him flare up.
"As you wish!"
"Dust Release: Detachment of the Primitive World Technique!"
"Ding!"
"Ōnoki dealt 800 points of damage to you!"
"Ding!"
"Ōnoki…"
Thus repeated more than ten times. In total, Ōnoki provided Kairen with 5,000 points of experience, enough for half a Chakra Fruit.
The old man panted heavily, leaning against a piece of broken rock.
A hand offered him a cup of water, along with attentive concern.
"Tired from fighting? Have some water!"
Ōnoki took the cup, gulped it down, and even thanked him. "Thank you, young man. Polite kids like you are rare these days!"
Ōnoki looked carefully—holy hell! It was Kairen's shadow clone.
Ōnoki jumped up and hurriedly moved away from the shadow clone.
"Brat, what do you want to do!"
Kairen's shadow clone smiled. "Aren't I just seeing that you're tired?"
"Get lost, I don't need your pity!"
Ōnoki roared.
"Hmph! Unappreciative."
After the shadow clone left, Kairen walked up with his arms crossed.
Ōnoki's face darkened. Kairen was uninjured and full of vigor.
He had been fighting for so long; the other side was perfectly fine, while he himself felt like he was about to run out of breath.
Kairen pointed not far away. "Look over there—what's that?"
Ōnoki looked in the direction Kairen pointed. A group of Iwagakure ninja were tied up with ropes, and beside them were shadow clones holding Heavy Machine Guns.
The captives stretched as far as the eye could see—almost the entire Iwagakure had been taken.
Ōnoki's expression tightened. He glared at Kairen.
"You little bastard, while I was dealing with you, you actually sneaked an attack on the village. You don't play fair."
Kairen smiled. "I just don't play fair. What can you do about it?"
"Hmph!"
Ōnoki stood up. Though he was still not even as tall as Kairen's crotch, he kept that stubborn look.
"Anyone in Iwagakure can surrender, except the Tsuchikage. I will die on the battlefield and will never lie down to die in shame."
Even though all his chakra was exhausted and he didn't even have the strength to stand steadily, Ōnoki still charged at Kairen like a warrior.
In a flash of lightning, Kairen caught Ōnoki's hand with one hand and blocked his attack.
Kairen directly grabbed Ōnoki by the collar and lifted him up.
"Are you really not surrendering?"
Ōnoki snorted. "No surrender. Absolutely not."
Kairen held Ōnoki up with one hand and clenched the other.
"Dust Release works like this, right?"
A layer of white chakra reacted in Kairen's palm, slowly forming a cube…
Ōnoki's eyes widened as he stared in disbelief at the energy in Kairen's palm.
"You—you—you—"
Kairen chuckled softly. "With that aged brain of yours, how could you understand the height I stand at?"
"What I've mastered is not just Dust Release!"
The chakra in Kairen's palm flowed rapidly. The energy grew deeper and deeper, slowly shifting toward a chaotic black.
Kairen softly said, "Dust Release is a mixture of three attributes of chakra. Then what about four, five, or even seven attributes mixed together?"
Ōnoki's eyes went wide. "Impossible. Humans can never master the mixing of seven types of chakra. Three is already the limit."
Ōnoki knew very well how difficult one-to-one chakra mixing was. He had trained Dust Release for most of his life.
The mixing and reactions of chakra would cause different energy reactions: water and fire become Boil Release; water and earth become Wood Release; wind and water become Ice Release…
Obtaining high-quality energy was not difficult, but the fusion of different chakra attributes had precise proportions.
Any arbitrary ratio would bring different reactions, and those reactions could even fatally injure the caster.
Ōnoki was already extremely cautious just mastering wind, fire, and earth, and he truly couldn't believe Kairen would master the fusion of seven chakra attributes.
Kairen smiled. "How can a mortal's gaze see the height of a handsome guy? Step back—I'm about to show off."
The chakra reaction in Kairen's palm grew more and more intense. The white Dust Release began to turn black.
That terrifying energy reaction released a heavy pressure, as if an atomic bomb were sleeping right beside you.
Such chaotic energy, in Kairen's hands, was like obedient little babies, listening to him perfectly.
In just two breaths, a black sphere appeared in Kairen's palm, with purple patterns circling it, like a tailed beast's Tailed Beast Ball.
To be precise, the Tailed Beast Ball is exactly in this form.
Ōnoki stared in disbelief. "You really made it! Unbelievable—truly unbelievable! Humans can really master the power of tailed beasts."
The corner of Kairen's mouth lifted into a faint smile as he slowly placed the Tailed Beast Ball on top of Ōnoki's head.
"Will you surrender or not?"
The touch of the Tailed Beast Ball brought a chilling sensation, but inside it was terrifyingly hot. Once it lost control, it would cause an enormous explosion over a huge area.
Ōnoki was panicking inside, but he still kept that stubborn expression.
"Keep dreaming!"
"Fine. I'll scatter you into a puff of air."
Kurotsuchi hurriedly jumped in and pleaded, "Don't! Don't kill the old man."
