Shaoyu took a deep breath and began to circulate chakra.
Golden light gushed out from his palm, which was his own chakra, mixed with the special properties of Limitless.
The light was like a warm tide, slowly seeping into Kurama's fur, into its flesh and blood, and into the red ocean of chakra in its body.
The moment the first ray of Nine-Tails Chakra poured into his body, Shaoyu's body stiffened suddenly.
It hurts.
The horse's pain really hurts.
That kind of pain is not ordinary pain, but a tearing feeling that bursts from the depths of the cells.
Nine-Tails's chakra is too huge and violent, and his body simply cannot bear it.
The blood vessels are expanding, the muscles are spasming, the bones are groaning, and every inch of flesh and blood is being stretched, torn, and burned by the force.
Cold sweat instantly broke out on his forehead.
But he didn't stop.
Chakra continues to pour in.
A red light appeared on his body surface, which was the leakage of Nine-Tails Chakra.
They were like countless tiny snakes, swimming under his skin. Wherever they passed, the skin would bulge out with twisted bulges.
Those bulges kept changing shapes, sometimes as if something was about to burst out of the body, and sometimes they slowly calmed down.
Shaoyu's breathing began to become rapid.
He could feel that his meridians were being stretched. Those originally slender channels were now being violently expanded by Nine-Tails Chakra, with their edges torn and blood oozing out.
It felt like someone was using a red-hot iron rod to forcefully open his blood vessels.
But his right hand was still pressed on Kurama's head, motionless.
Reverse Cursed Technique, open.
The golden light lit up again, this time pouring out of his body.
The light penetrated into the torn meridians, penetrated into the broken cells, and began to repair frantically.
Tear--repair--tear again--repair again.
Two forces started a tug-of-war within his body. Nine-Tails Chakra was responsible for destruction, and Reverse Cursed Technique was responsible for reconstruction.
Every tear brings excruciating pain, and every repair slightly relieves that pain.
But then, the next tear came again, more violently and completely.
Shaoyu's face turned pale.
Sweat had soaked through his clothes, dripped down his chin, and formed a small puddle on the ground.
His body was shaking uncontrollably, which was the instinctive reaction of his muscles under extreme load.
His teeth clenched as he used his last willpower to suppress the urge to scream.
Kurama opened his eyes and looked at him.
A trace of complicated emotions flashed through those blood-red eyes.
It has seen too many births of Jinchūriki. When those humans were sealed by Tailed Beast, they were all in great pain. Some people died of pain, some went crazy, and some people survived, but they became distorted from then on.
But the human being in front of him remained silent from beginning to end.
Because Shaoyu's physical fitness has been strengthened through Jashin, and is now stronger than Third Raikage. Otherwise, he may not be able to succeed.
"Boy." Kurama's voice sounded in his mind.
"Is everything okay?"
"No... it's okay... hiss..."
This time, not a single meridian, but all the meridians in the whole body collapsed at the same time.
It felt like countless knives were piercing his body at the same time and then stirring at the same time. His vision went dark and he almost fainted.
But Reverse Cursed Technique started again.
Golden light poured out from every corner of the body, reconnecting the broken meridians.
Wherever the light passed, the new meridians were tougher and wider than before, and more able to accommodate the power of Nine-Tails.
Shaoyu's breathing finally calmed down a little.
But he knew that this was just the beginning.
Nine-Tails's chakra is still pouring in.
Those red powers no longer just stay in the meridians.
They began to penetrate into his muscles, into his bones, into his internal organs, into every cell of his body.
Muscles are being torn.
It felt like countless hands tearing at every muscle in his body at the same time.
The chest muscles, back muscles, abdominal muscles, and muscles of the limbs are all being torn apart and reorganized by that force.
He could clearly feel that his muscle fibers were broken one by one, and then regenerated one by one.
Bones are being remodeled.
That is a more painful experience. Bones are not as elastic as muscles, they can only be stretched, broken, and then healed.
He could hear the clicking sounds coming from his body. It was ribs breaking, the spine deforming, and the bones of the limbs rearranging.
Internal organs are being strengthened.
The beating speed of the heart became extremely fast, as fast as hundreds of times per minute, as if it was about to explode at any time.
Breathing in the lungs became difficult, as if something was blocked there. The liver, kidneys, spleen, and every internal organ were being penetrated, transformed, and strengthened by Nine-Tails Chakra.
It felt like someone was stirring in his stomach.
Shaoyu's body began to change.
Faint red lines began to appear on the surface of his skin.
That was the leakage of Nine-Tails Chakra, a sign that the power could not be completely restrained.
Those lines were like living things, running under his skin, sometimes lighting up and sometimes dimming.
His eyes also began to change.
The originally dark pupils were now glowing with a faint golden color.
That is the result of mixing Reverse Cursed Technique and Nine-Tails Chakra. It is a brand new color that has never appeared before.
The eyes were now wide open, with the pupils sometimes dilating and sometimes shrinking, which was an instinctive reaction of extreme pain.
His nails began to grow longer and pointed.
That's one of the characteristics of Nine-Tails.
Although he has not turned into a fox, some characteristics belonging to Tailed Beast have begun to appear on him.
The nails become like animal claws, hard and sharp, the teeth also become sharp, and you can feel an inexplicable force when biting.
Kurama watched all this quietly.
It feels it.
This human body is being completely transformed by Nine-Tails Chakra.
Those tears, those pains, those crazy changes are all part of transformation.
"Boy." Kurama spoke again, "Are you still conscious?"
Shaoyu's lips moved.
"Yes, brothers do."
Nine-Tails's mouth twitched.
This kid's physical fitness is really strong. You need to know what the previous Nine-Tails Jinchuriki was. Only Uzumaki Clan people can withstand its power. Others can't do it at all. Master Nine-Tails is not like the other Tailed Beasts. Its power is very powerful.
But the kid in front of me actually has a physical fitness and recovery ability comparable to the Uzumaki Clan. It has to be said that he is really a monster.
It looks like he is really the reincarnation of Indra...
Kurama was silent for a moment.
Then, it made a decision.
It begins to actively release more chakra.
