Chakra and first kill.

Leaning away from another incoming strike, he executed a roundhouse kick on his opponent, who happened to be another version of himself.

Wood clones proved incredibly convenient, especially for sparring and entertainment purposes.

With a mere thought, he dispelled the clone jutsu and resumed walking. The fragmented memories he had inherited from Urashiki Otsutsuki contained a wealth of information.

Among these memories, he also witnessed Urashiki getting his shit kicked out of him by some dregs, leaving him bewildered.

What perplexed him even more was how Urashiki could be harmed by a simple spinning ball of chakra when he possessed the ability to absorb it effortlessly.

He thought, 'What a fool he was. He could have been the strongest if he had used his abilities effectively.'

Shaking his head as he continued walking, he thought, 'I should find a town or something.'

'Even though I have the pride of an Otsutsuki, I lack strength right now, so I should lay low and wait for the karma to finish extracting,' he pondered as he moved forward.

He was determined not to repeat Urashiki's mistakes, such as underestimating his enemies and being too arrogant, without the power or skill to back it up.

With the information he had about the Akatsuki and its puppet leader, as well as the revelation that Kaguya Otsutsuki's third son, Zetsu, was manipulating the real leader, he knew he had to make the most of his current situation.

Traveling discreetly with his chakra signature erased, he made his way from the Land of Noodles to the Land of Water, heading towards Kirigakure.

The Tailed Beast's chakra that he had absorbed, the Hidden Mist Village seemed to have claimed it as their own.

Additionally, he detected another chakra similar to that of a Tailed Beast, possibly indicating the presence of another Tailed Beast in the vicinity.

The chakra he acquired from the three-tailed beast was not only potent but delicious. He became entranced by its power, and on that day, he nearly didn't stop the absorption process. Only when the beast's chakra reserves dangerously dwindled did he halt the absorption.

Unfortunately, he lacked the knowledge of genjutsu or any means to make the tailed beast forget what transpired.

This meant that the three-tails likely shared its experience with its siblings, warning them that a chakra-absorbing man was hunting them down.

Landing on the outskirts of the Land of Water, he sensed another substantial reservoir of chakra emanating from the Hidden Mist Village. If he wasn't mistaken, that was their Kage.

'Not bad for a human, but Uzumaki Naruto still possesses more,' he thought, impressed by the amount of chakra a human could muster. 'I have to take the Nine-Tails' chakra anyway.'

His plan was to gather and combine all nine tailed beasts' chakra to create the Ten-Tails' chakra. Then, he could transform that chakra into a fruit and plant it.

This fruit would grow into another Divine Tree, which, after some time, would become the Ten-Tails again.

Subsequently, it would become the Divine Tree once more, requiring the sacrifice of an Otsutsuki. Afterward, it would bear a chakra fruit that he could consume.

After wandering around and enjoying some sightseeing, he took to the sky once it was night. Tonight, his plan was to harvest the chakra of another Tailed Beast.

Examining his palm, he beheld a small pill, about the size of a ping pong ball. This was the residual chakra of the Three-Tails that remained after he had consumed a substantial portion.

He planned to gather all the Tailed Beast chakra into the pill in his hand and convert it into a chakra seed which he shall later plant.

"Heh, wonder what I should do?" he muttered to himself as he flew through the air like a projectile toward the Tailed Beast.

Upon arriving, he couldn't see the Tailed Beast itself, but he spotted its Jinchuuriki, a red-haired man sitting beneath a tree, either meditating or lost in deep thought.

Roshi remained in a state of calm meditation, even with Shinshiki floating nearby.

However, without any conscious thought, Shinshiki extended his hand and activated his chakra absorption technique.

This sudden action caught Roshi's attention, but he found himself unable to move due to the paralysis caused by the absorption.

It seemed that only his Karma allowed him to achieve such an effect, as he couldn't utilize Urashiki's chakra-stealing rod.

For now, the paralysis transferred to the karma until he could utilize the weapon for himself.

After some time, the red chakra that was being absorbed into his karma ceased, and Shinshiki halted the absorption process.

Roshi, now drained and weakened, tumbled to the ground, his body exhausted from losing nearly his entire chakra reserve.

Over 70% of the tailed beast's chakra had also been extracted by Shinshiki.

Inspecting the fifteen chakra pills in his grasp, he opted to ingest ten of them, resulting in an immediate surge of tremendous power.

His body underwent a new transformation as his karma mark extended once again, stretching from his forehead to the back of his head, from which his horns started to sprout.

This time, the horns grew differently, originating from the sides of his forehead and curving around to the back, resembling those of a goat.

Feeling an unimaginable surge of power coursing through his body, he clenched his fists so tightly that his nails cut into his palms, only to regenerate instantly.

"You, monkey. You have my gratitude, but even so, you have to go," he said with authority and descended down and in front of Roshi.

Who was close to being knocked out, as he raised his leg to kick Roshi's head and end him without giving unnecessary pain, only to find himself jumping back and to absorb a lava ball which left Roshi's mouth.

"Now you've done it, you pest." Raising his hand and absorbing the remaining lava bullets, he saw Roshi was making a distraction for him to run.

Activating the Byakugan, he saw Roshi's face getting washed with a frown, he smirked as he disappeared from place, appearing in front of the jinchuuriki, he kicked his head so hard that he flew and was slammed into the roots of the big tree where he had been meditating earlier, destroying it as well.

"Heh," he sneered as he looked at Roshi's head impaled by the stake when the tree's massive roots cracked. Then, without further ado, he ascended into the night sky once again.

"That foolish bastard," he muttered, "if he had gone out without resistance, he would've had a painless death. Now, look what he's done."

"Not that I care anyway, these inferior creatures always struggle even when at death's door, it's quite amusing."

He flew away, contemplating his next move, thoughts swirling like a tempest, seeking new entertainment in this shinobi world with newfound power, for now.
