Uchiha Kai, watching from the side, felt that this Nawaki was really similar to the young Naruto Uzumaki, especially when he acted foolish. It was as if they were cut from the same mold.
However, this could be understood, after all, Nawaki was also the reincarnation of Ashura's chakra, just not as lucky as Senju Hashirama or Naruto Uzumaki. He had fallen at a young age.
This directly proved that in the ninja world, even if you were the reincarnation of the Six Paths Sage's son, you could still die when it's your time. There would be no protagonist halo to protect you.
In this situation, an hour quietly passed.
When the skill duration ended, Nawaki felt a pull of some kind of power, but he immediately rejected the sensation of being dragged.
In an instant, the strange feeling disappeared, and he had not left, still existing in this vast mental network world.
This situation made Uchiha Kai clench his fist, a joyful smile appearing on his face, while Orochimaru, seeing Uchiha Kai's reaction, understood what it meant and couldn't help but chuckle.
Clearly, the experimental plan Uchiha Kai proposed had succeeded. Nawaki did not return to the Pure Land in the ninja world just because the hour limit was up.
At that moment, Orochimaru pulled Nawaki over to express his gratitude to Uchiha Kai.
Although he had already thanked him before, this time it was something different.
However, Nawaki was unaware of the twists and turns behind the scenes.
All he knew was that his teacher, Orochimaru, was going to thank his benefactor again.
As someone who valued gratitude, he, of course, had to follow his teacher's lead and express his thanks to the benefactor.
For a moment, the atmosphere between the group was quite harmonious and friendly. They then took the opportunity to make a request to Nawaki, hoping he could help treat his sister, Tsunade's mental illness.
This left Nawaki in shock.
"What? My sister? My sister has a mental illness? What is a mental illness? Wait, isn't she an incredibly skilled medical ninja? What kind of illness could she possibly have that she can't cure?"
This was a classic case of ignorance, fully showcasing the educational level in the ninja world.
However, Nawaki died when he was only twelve, so it was normal for him to have no understanding of such things.
Therefore, Uchiha Kai didn't bother criticizing and directly explained the issue of mental illness and hemophobia, as well as how Tsunade became ill.
After learning everything, Nawaki was deeply surprised and filled with guilt. He never imagined that his death would cause his sister to develop hemophobia.
This was something that was incredibly difficult for him to accept and caused him great distress.
This situation made Nawaki, who cared so much for his sister, feel immense regret and pain. He instantly felt like "I really should die," and in his sorrow, he slapped himself a few times, wishing he could fall asleep in despair.
The change in his mood was visibly noticeable.
Clearly, he was the type of brother who would rather suffer himself than see his sister in pain — a classic example of a devoted younger brother who respects his sister.
However, Uchiha Kai and Orochimaru didn't bring Nawaki back just for him to wallow in self-pity.
Once they confirmed that the skill bug was successful and that Nawaki wouldn't leave, they could proceed with the plan to help Tsunade.
At that moment, Uchiha Kai and Orochimaru informed Nawaki that they had summoned his soul to help Tsunade.
After learning the full story, Nawaki immediately pounded his chest and promised to do everything in his power to help his sister. He would do whatever he could.
However, he was still very worried because he had no idea how to treat Tsunade's hemophobia and was afraid of messing things up.
In response, Uchiha Kai reassured him that there was no need to worry. The entire treatment plan had been formulated by him and Orochimaru, and all Nawaki needed to do was cooperate. He didn't need to think about it.
This was exactly what Nawaki was good at, and it eased his mind. He confidently vowed to do his best.
Next, they would discuss the specific plan to treat Tsunade.
Uchiha Kai had already prepared and immediately took it out.
After knowing the cause and effect, Orochimaru couldn't help but ask with some concern, "Is this really going to work? Kai-kun. Won't it backfire and make Tsunade's hemophobia worse?"
Uchiha Kai waved his hand nonchalantly.
"Tsunade's condition is already at the most severe stage of hemophobia. There's no more room for it to worsen. Even if she meets with Nawaki in this state, it will likely take a long time to fully treat her."
"We don't have that much time to wait. With the Third Great Ninja War about to begin at any moment, Tsunade must recover as quickly as possible. That's why I've decided to use a stronger approach."
Orochimaru fell silent and then nodded. "Then, let's do it your way."
Though Nawaki didn't fully understand the situation, he saw that his teacher, Orochimaru, agreed, so he immediately followed Uchiha Kai's plan.
And so, the plan to save Tsunade was set in motion. Not long after, in a tavern in Konoha, Tsunade, who was drinking alone, suddenly noticed two people appear beside her.
Tsunade, lost in thought while drinking and reflecting on the past, was interrupted and frowned.
A slight flush of drunkenness turned into a scowl on her face, and she immediately looked up at the two uninvited people sitting next to her.
When she saw who they were, Tsunade froze for a moment before clicking her tongue in displeasure.
"Orochimaru, how did you get here? Did the old man tell you? And why are you with Uchiha Kai?"
As she spoke, her gaze moved past her old friend, Orochimaru, and focused on Uchiha Kai.
At that moment, Tsunade's expression was complex.
In the past, she only saw Uchiha Kai as a friend of Jiraiya's disciple—someone from the Uchiha clan, but an ordinary person who was stuck with the Sharingan, lacking significant power. He wasn't worthy of her attention, and she merely knew him as a simple acquaintance.
But now, everything was different.
Uchiha Kai, who had developed the Genjutsu game, had become a unique figure in Konoha.
He had brought about huge changes for the entire Uchiha clan, pushing them forward in ways they hadn't in decades.
In a short period, he had improved relations with other major ninja clans while simultaneously pulling them into his cause.
Most importantly, the Genjutsu game he developed was impressive—not only was it extremely realistic, but it also offered an indescribable experience.
Because of the genjutsu game, Tsunade's hemophobia fully erupted, leading her to become the depressed figure she is now. It truly feels like fate playing tricks.
This is why Tsunade's gaze towards Uchiha Kai was so complicated.
However, there was no blame in her eyes.
From Tsunade's perspective, the genjutsu game by Uchiha Kai was indeed a trigger, but the true cause of her hemophobia was the cruel Ninja World Wars.
