The young man let out a series of miserable screams where he stood.
The power of Karma continued to spread within his body, reaching every part of him and erupting everywhere at this moment.
Without a doubt, this was a painful process.
The modification of a body by Kaguyas Seal Power was not easy; it inevitably destroyed the body during the process, bringing intense pain.
During this process, Minamikawa Yuu just stood to the side, quietly watching him.
"Don't resist."
After a good while, he finally spoke: "Keep your body stable, and you'll be fine."
He spoke softly, and in the next moment, he leaned down and placed a hand on the man's chest.
Along with the delivery of his Chakra, the man before him seemed to stabilize significantly. His entire body gradually regained its calm, and the violent struggling from before ceased.
After a considerable amount of time passed, his body finally stabilized completely.
"So it's such a process."
Minamikawa Yuu observed the entire transformation process, watching with great interest.
Using the Kaguyas Seal Power within himself to infect others was an operation he was performing for the first time.
Back in the Land of Ancestors period, although Minamikawa Yuu also had Kaguyas Seal Power in his body, the Karma at that time did not belong to Minamikawa Yuu, but to Kaguya.
Strictly speaking, Minamikawa Yuu was merely someone infected by Kaguya's Kaguyas Seal Power, not the owner of it.
But the Kaguyas Seal Power Minamikawa Yuu was using now had been modified by the system panel and belonged entirely to himself.
Although the Kaguyas Seal Power Minamikawa Yuu possessed was not yet powerful compared to Kaguya's strength—he could only use a small fraction of it—it was still the power of Karma after all.
There was a significant difference in how it was actually used.
"After being modified by Karma, his physical fitness has improved a lot, and the life energy in his body has become more vigorous..."
"It's hard to say about the mental aspect, but the increase in life energy alone is enough to grow the Chakra in his body by more than half."
Through his own perception, many thoughts flashed through Minamikawa Yuu's mind: "Additionally, using Kaguyas Seal Power as the core, a Karma Mark has been planted in his body."
"This is like planting a seed. It is normally nourished by the other person's own Chakra and life, growing continuously. When I need it in the future, I can easily take it back."
Minamikawa Yuu thought quietly to himself.
During the time since returning to his original body, he had been pondering ways to use Karma.
The method before him was undoubtedly the most efficient way he had discovered.
By sharing his own Kaguyas Seal Power and planting marks in others, he could obtain a certain degree of power feedback from them.
When needed, he could reclaim the Kaguyas Seal Power within them to strengthen himself once again.
To Minamikawa Yuu, this was equivalent to farming.
Planting a seed in spring, using the other person's body to grow the Karma Mark to a certain extent, and then harvesting it when the time was right.
Of course, this process wasn't something everyone could undergo.
There was a threshold for enduring Kaguyas Seal Power. If one's physical fitness and Chakra weren't strong enough, they would likely collapse and die during the process of bearing Karma.
According to Minamikawa Yuu's own estimations, to safely bear Kaguyas Seal Power—even this simplified version—one would need to be at least at the Jonin level to be considered relatively safe.
"My power..."
While he was thinking, the person in front of him also gradually regained consciousness.
The young man rose from the ground and was stunned as he felt the changes in his body.
After the modification by Kaguyas Seal Power, he could clearly feel the changes in himself.
The power of Karma circulated within him, making his physical fitness much stronger and even increasing his Chakra strength, making him far more powerful than before.
If he was previously at an average level among Jonin, now, with the enhancement of Karma's power, his strength had taken a massive step forward, approaching that of an Elite Jonin.
Minamikawa Yuu stood there, looking at the young man with interest.
"What is your name?"
After a moment, he spoke again, asking for the other's name.
"I am Yamame Choshin."
Meeting Minamikawa Yuu's gaze, the young man quickly reacted.
He knelt on one knee, quickly adjusting his attitude, and looked at Minamikawa Yuu with a respectful expression: "Greetings, Excellency."
"Yamame Choshin, is it..."
Minamikawa Yuu nodded: "From today on, you are a member of the Night Organization."
"Your mission is simple: just remain undercover in Iwagakure."
He spoke calmly: "Try your best to ensure your own safety and wait for my summons."
"Yes."
Yamame Choshin nodded, indicating there was no problem.
"In Iwagakure, are there many people like you?"
After the two exchanged words for a bit, Minamikawa Yuu suddenly spoke.
"People like me?"
Hearing Minamikawa Yuu's words, Yamame Choshin didn't react at first.
However, he soon realized Minamikawa Yuu's meaning and continued: "Most Ninja in Iwagakure are loyal to the Tsuchikage, but there are also many who are dissatisfied with the Third Hokage."
"If there is no other force influencing them, they will continue to obey the Third's orders, but if something were to happen to the Third Hokage, the situation might become different."
He spoke thus, revealing Iwagakure's intelligence piece by piece.
Minamikawa Yuu listened carefully and then shook his head.
"It looks like the situation within Iwagakure is quite stable, much stronger than other Ninja villages."
This thought flashed through his mind.
In the Ninja World, the Five Great Ninja Villages were undoubtedly the most powerful forces.
But among these Five Great Ninja Villages, there were also differences.
Among the major villages, Kumogakure and Iwagakure were undoubtedly the most stable two.
The former goes without saying, and the latter has been ruled by the Third Tsuchikage for many years, becoming extremely stable long ago.
If one wanted to make a move against the Five Great Ninja Villages, these two villages were undoubtedly the ones with the lowest cost-performance ratio.
"As expected, if I want to do something, Hidden Mist and the Sand Village would undoubtedly be more suitable."
Standing there, Minamikawa Yuu shook his head: "Especially Hidden Mist..."
Among the Five Great Ninja Villages, if one wanted to do something, Hidden Mist undoubtedly had the lowest difficulty.
The reason was none other than the presence of Obito.
Compared to the other nations, Hidden Mist's internal policies were already among the most radical and bloody.
Problems were naturally prone to arise under high-pressure rule.
On this basis, with the Fourth Mizukage being controlled later on, a 'Bloody Mist Village' was created directly under Obito's manipulation.
At that time, it would be extremely easy to make some moves.
After talking with Yamame Choshin for a while, Minamikawa Yuu let him leave.
As for whether the other party was loyal, he didn't care.
From the moment he planted the Karma, the other party had no way back.
Having been planted with his Karma, as long as he wished, he could trigger the Kaguyas Seal Power within the other's body at any time.
Once it reached that step, the other party would surely die.
If the other party was sensible, that would be fine, but if they weren't, then he could just find someone else later.
