Having initially completed the development of 'Karma', Shinji didn't stay but immediately went to the central training ground.
The crowd who were sparring here before had already dispersed. During this period, the strength of many people had qualitatively improved, leading to everyone catching up with each other and entering a healthy competition. So after witnessing Haku's 'Sage Mode', everyone consciously returned to their own training grounds to cultivate.
After summoning Karin to the central training ground through 'Jikibi', Shinji asked Karin if she was willing to accept the 'Karma' experiment.
After understanding what 'Karma' was, Karin asked: "My Lord, if something happens to you, can you resurrect in my body through the 'Karma' on me?"
"Hmm, theoretically yes."
Shinji didn't hide it, admitting openly.
"Okay!"
Hearing this, Karin agreed without hesitation.
"Currently it's just a trial version. Although your constitution is very strong, there are still certain risks. So you must be careful. If you feel anything wrong with your body, stop immediately."
After exhorting, Shinji implanted 'Karma' onto Karin's back.
With the implantation of 'Karma', normal rejection phenomena appeared in Karin's body. She knelt halfway on the ground, gasping for breath.
After a while, she gradually adapted to 'Karma', saying with some wonder on her face: "My Lord, I feel your chakra!"
Shinji nodded: "This is 'Karma'!"
Frankly speaking, the 'Karma' Shinji implanted into Karin was still different from the 'Karma' used by the Otsutsuki clan for reincarnation.
Shinji's 'Karma' was more of a power transmission, somewhat similar to the 'Yang Power' and 'Yin Power' bestowed by the 'Sage of Six Paths' to Naruto and Sasuke in the original timeline.
The difference was that the 'Yang Power' and 'Yin Power' bestowed by the 'Sage of Six Paths' were non-renewable, used up once used. While the 'Karma' he implanted into Karin could be used repeatedly as long as he himself had no problems.
Of course, every time Karin activated 'Karma', she would be eroded by Shinji's consciousness in 'Karma'. Even if Shinji reduced the degree of this erosion, the influence couldn't be completely avoided. So 'Karma' could only be used as a decisive battle weapon, used as little as possible.
When Karin fully adapted, Shinji said: "Try activating 'Karma'!"
"Yes!"
Karin responded, trying to communicate with 'Karma'.
The activation of 'Karma' developed by Shinji was not complicated, so Karin quickly figured out the method to activate 'Karma' and successfully activated it.
Swish...
With the activation of 'Karma', countless ink-colored patterns spread out from the mark of 'Karma', covering most of Karin's body.
At the same time, the chakra in Karin's body climbed rapidly. In just the blink of an eye, her strength reached an unprecedented height.
"Just a little bit more!"
Shinji frowned, a nervous expression appearing on his face.
The success or failure of the 'Karma Plan' depended on this moment!
At this time, Karin seemed to be still immersed in the power of 'Karma', her eyes somewhat glazed, as if under some kind of genjutsu.
Seeing this, Shinji shouted softly: "Karin!"
Hearing this, Karin instantly came back to her senses, frowning slightly: "My Lord, was I absent-minded just now?"
"Hmm!" Nodding, Shinji asked: "How do you feel now?"
Karin answered: "I feel like there is endless power in my body, it's just..."
Shinji pursued: "Just what?"
"Just feel like I'm becoming somewhat unlike myself!" Stabilizing her mind, Karin continued: "I should be influenced by the will you left in 'Karma'!"
At this time, Shinji noticed layers of petrified keratin appearing on Karin's skin again, so he said in a deep voice: "Now you can only rely on yourself. Only by firming your will can you master the power I left in 'Karma'. Otherwise, you must deactivate 'Karma' within three minutes!"
"I understand!"
Karin nodded, closing her eyes.
Time passed bit by bit, and the aura on Karin's body fluctuated between strong and weak. Such abnormality soon attracted everyone.
Seeing Karin closing her eyes and remaining silent in the field, and Shinji looking solemn, everyone stood by the field watching quietly.
Three minutes passed in a flash. Just as Karin was about to reach three minutes of activating 'Karma', the aura on her body suddenly changed. Then, with a 'swish', an ink-colored 'Truth-Seeking Ball' appeared on her back, followed by the second, the third...
Until the ninth 'Truth-Seeking Ball' appeared!
"That is..."
"It's 'Truth-Seeking Ball'!"
"Karin stepped into that level?"
The onlookers were all shocked.
Because of Shinji, everyone knew the most prominent feature of 'Six Paths Level' was being able to condense 'Truth-Seeking Balls'.
So when seeing the nine 'Truth-Seeking Balls' floating behind Karin, everyone instantly understood Karin crossed that boundary, becoming an existence like a real Otsutsuki!
At this time, Karin slowly opened her eyes: "My Lord!"
Shinji smiled with relief: "Well done!"
Regardless of whether this model could be successfully copied to Hikari and Sasuke, Karin's success alone showed that Shinji's 'Karma Plan' was at least theoretically feasible.
He successfully created a 'Six Paths Level' powerhouse!
At this time, everyone gathered around, especially Hikari and Sasuke. They looked enviously at the 'Truth-Seeking Balls' floating behind Karin and asked: "How did you do it?"
Karin looked at Shinji.
Regarding 'Karma', she didn't know much either.
Shinji explained slowly: "Currently still in the experimental stage. You go back first. I will tell you when the experiment is completed!"
Sending away the reluctant crowd, Shinji had Karin deactivate 'Karma', and then inquired in detail about Karin's feelings on activating 'Karma' for the first time, especially if there was any physical discomfort.
Because Karin's constitution was the strongest under his command besides Shion and Toneri Otsutsuki. The minor discomfort she felt might be a big problem for others.
After collecting all of Karin's feelings after activating 'Karma' in detail, Shinji began fine-tuning 'Karma'.
From Karin's feedback, this version of 'Karma' he developed basically met his needs.
What he needed to do now was to fine-tune this version of 'Karma', further improving stability while reducing the manufacturing cost of 'Karma'. Because based on this version of 'Karma' implanted in Karin's body, he could at most maintain two 'Karmas'.
And under his command, there were a total of three people, Karin, Hikari, and Sasuke, who could break through 'Six Paths Level' with the help of 'Karma's power!
So he must adjust the intensity of a single 'Karma', allowing himself to manufacture and maintain three 'Karmas', while ensuring Karin, Hikari, and Sasuke could successfully break through to 'Six Paths Level' with the help of 'Karma's power...
