With the confirmation of the Dark Release clone, Kōki's tense expression relaxed.
He looked at the Dark Release clone curiously and said, "Since you say you have more precise control over the Dark Release Kekkei Genkai power, why don't you show us?"
Seeing the main body's curious expression, the clone of the Dark Release didn't refuse; it stretched out its right hand.
A strange wind suddenly appeared in the closed room, and then, under the control of the Dark Release Clone, the wind spread outwards, instantly filling the entire room.
Upon seeing the Dark Release clone's movements, Kōki was initially puzzled, then realized that his own Chakra was slowly disappearing.
However, this feeling was so subtle that if he hadn't been paying close attention to the changes in himself, he would have thought it was just an illusion.
To more clearly verify the effects of Dark Release, a rapidly spinning ball of Chakra energy glowing blue appeared in Kōki's hand. This was the Rasengan, a no-seal Ninjutsu that would later be popularized by Naruto Uzumaki, the protagonist of the Shinobi World Rasengan.
He had long mastered this Ninjutsu, but he thought Ninjutsu was not as useful as his Superhuman Strength Technique, so he had always kept it on a shelf.
This time, we need to directly test the power of Dark Release, and this obvious Chakra energy cluster is perfect.
After he unleashed the Rasengan, a strange phenomenon occurred.
The Rasengan in his hand was pulled by an invisible force, making it difficult to maintain its original shape. Then, under his gaze, the Chakra ball became smaller and smaller.
This scene greatly intrigued Kōki, and at the same time, he wanted to test the limits of his Dark Release.
Before the Rasengan disappeared, he increased Chakra Rasengan output to it, and the Rasengan, which had shrunk to the size of a marble, instantly grew back to its original size.
However, the Dark Release Kekkei Genkai Controlled by the Dark Release clone was like a bottomless pit, constantly devouring the Chakra Kōki outputting.
Soon, after feeling nearly half of his Chakra being devoured, Kōki gave up on maintaining the Rasengan and stopped channeling Chakra into it. As a result of his actions, the Rasengan in his hand was eventually completely devoured by the Dark Release.
After the simple experiment, Kōki could tell from the nonchalant expression on the Dark Release clone's face that maintaining the Dark Release Kekkei Genkai was not a big burden for him.
"Is there anything special about this move?" Kōki sensed that this Dark Release technique was very well concealed, and it would be difficult for anyone to detect it unless they were specifically observing it.
"This technique is Dark Release Barrier that I created. As long as a person is inside this technique, they will continuously lose Chakra. The area it covers is also quite large; if I use it at full power, it can encompass a quarter of Konoha."
"This technique is also very well concealed, making it difficult for the enemy to detect during battle. The Chakra lost by the enemy can also be used by me," Jörmungandr said calmly.
Furthermore, there were some crucial points he didn't mention: within the range of this technique, any Ninjutsu used by the enemy will be weakened.
Of course, there are also some weaknesses. For example, the larger the range of his attacks, the weaker his ability to absorb Chakra, and the worse his ability to weaken Ninjutsu.
Looking at the calm-faced Dark Release clone, Kōki asked curiously, "Can you keep absorbing chakra? I noticed that the Chakra you just absorbed has already exceeded your own capacity."
In his perception, the Chakra absorbed by the Dark Release clone was more than five times the Dark Release's own Chakra. But even with so much Chakra, the Dark Release clone didn't burst. He couldn't understand it.
In response to Kōki's question, the Dark Release clone said, "I don't know if I can keep absorbing it indefinitely, but at least I didn't feel any discomfort while absorbing your Chakra. As for your question about Chakra capacity, I can't answer that either, but I can certainly withstand Chakra exceeding my own capacity."
"However, I can sense that there is a limit to the amount of Chakra Dark Release can absorb. In the original story Hiruko absorbed so much Chakra in the early stages that he wreaked havoc."
"Later on, they were powerless against Naruto Uzumaki's Wind Release: Rasenshuriken. I suspect it's because the Dark Release's Chakra absorption capacity had reached its limit."
"You should know that Hiruko absorbed a large amount of Chakra in the previous battle, but only released a small portion of it."
"This means there's a large amount of Chakra in his body, squeezing out the space he can continue to use Dark Release to absorb Chakra."
"This is precisely why he failed to absorb the Rasenshuriken and ultimately died at the hands of the protagonist Naruto Uzumaki. This also explains why Dark Release can absorb Ninjutsu and Chakra but cannot absorb the Rasenshuriken."
Upon hearing this, Kōki suddenly realized that he couldn't understand it when he watched this movie in his previous life. How could someone with the ability to absorb Chakra and Ninjutsu, who possessed the Dark Release, die at the hands of the protagonist's Ninjutsu? The protagonist's halo was too strong and unreasonable.
Now that the user of the Dark Release has personally appeared and explained, his questions about his past life have been answered.
Thinking about this, Kōki realized that it wasn't surprising that the Dark Release Kekkei Genkai limit was achievable; he knew that every Kekkei Genkai had its limits.
Even the Sharingan in the original work, comes at a price. The Mangekyō Sharingan requires the death of friends, the Eternal Eye Sharingan requires the death of brothers, and the Rinnegan requires the death of close friends. It can be said that a whole circle of people around you has to die before you have a chance to achieve the highest level of Sharingan.
However, this once again demonstrates the boundless potential of the Sharingan.
You can gain power that surpasses everything by paying a sufficient price.
Only through continuous evolution of Kekkei Genkai can the Uchiha Clan uphold its prestige, which explains why the Uchiha Clan is so proud.
Kōki's thoughts drifted to the Sharingan of the Uchiha Clan, and he felt that he still couldn't do without the Uchiha Clan on his path to godhood.
It seems necessary to find an opportunity to have Aizen and the others recruit some valuable Uchiha Clan.
The thought that he might one day have the chance to experience the thrill of piloting a Gundam made Kōki chuckle.
"Hey, hey, hey, what are you thinking about, so happy?" The Dark Release clone, still explaining the effects and limitations of Dark Release, looked at its grinning main body and couldn't help but feel exasperated. He was explaining so earnestly, and its main body was already daydreaming?
Kōki, who was awakened from his wonderful vision by his own clone, was still a little unsatisfied. He had just imagined himself piloting a Gundam and running rampant in the Shinobi World.
"It's nothing, I was just thinking about some happy things."
"But since Dark Release has a limit to the amount of Chakra it can absorb, can we use Sealing Jutsu to expand that limit?"
"Just like sealing the Tailed Beast, which are known as Chakra aggregates, into a human body to form Jinchūriki, we can also seal our excess Chakra into our bodies. Wouldn't that be equivalent to having a powerful Chakra battery?"
At this moment, Kōki's words made both the Dark Release clone and Aizen's eyes light up.
This is indeed a good method. Since there is Sealing Jutsu that can seal such a huge amount of Chakra as a Tailed Beast into the human body, it should be no problem to seal the absorbed Chakra into one's own body.
