"Huh?" Setsuna felt like he was hearing a tall tale. He had been a Ninjutsu idiot for over ten years, and now Don Slime suddenly told him he actually wasn't lacking in Ninjutsu talent?
Suppressing his urge to complain, Setsuna asked, "Why do you say that?"
"I just discovered it. That little fox's Chakra accidentally mixed into that woman's body, forming 'impurities' that interfere with hand seals. Aside from her own strong innate talent for sealing techniques, she probably can't use a single Ninjutsu either."
Setsuna had to marvel, 'Don Slime truly lived up to his former title as Cosmic Emperor. Having just come into contact with the Chakra System, he could discern so many intricacies in such a short time.'
"What about me?"
"You?" Don Slime pondered for a moment before saying, "There's also a strange foreign energy inside your body interfering with your hand seals. That's why you can't precisely control and release Chakra. Only attacks like Ki or Taijutsu, which don't require guidance and can release energy rapidly, are unaffected."
Setsuna fell silent, 'I thought I had Rock Lee's situation, but I actually had Naruto's template?'
"So, you're saying if it's a seal-less Ninjutsu, I can practice it normally?"
"Theoretically, yes," Don Slime nodded, putting on the airs of a Ninjutsu Master.
Even so, Setsuna had no intention of urging Minato to develop the Rasengan any faster.
He could only practice seal-less Ninjutsu normally, but that didn't mean he had become a Ninjutsu Genius. Moreover, the Rasengan's power might not even surpass the force of his casual strikes.
In a way, he should be grateful for this foreign energy. It prevented him from diving headfirst into the deep pit of Ninjutsu.
Without those eight years of foundational Taijutsu training, he might not have achieved such growth in the Dragon Ball world.
As for the Flying Thunder God Technique, he could ask Minato for guidance when he had time, to see if he had any talent in that area.
"But what is the origin of this foreign energy?" Setsuna asked seriously.
Anyone would feel uneasy knowing there was an unknown source of power suddenly inside them.
Don Slime shook his head slightly. "I don't know. The source of this power is different from the Tailed Beasts. If the Tailed Beasts are sealed in after birth, then this power is inherently deeply bound to your soul, present within your soul even before you were born. That's why I didn't notice it at first."
Hearing Don Slime's words, Setsuna's first thought was the All-World Pearl.
But he quickly dismissed it, 'All-World Pearl, capable of taking me across universes, shouldn't be that low-level, right?'
'Could it be Otsutsuki Isshiki?' Setsuna then thought of this villain from the Boruto era, who seemed to parasitize humans.
But he still felt it was wrong, 'Even if Otsutsuki Isshiki had noticed my uniqueness, it should have been after my birth, right?'
After a moment's thought, Setsuna shook his head. "Forget it, no use thinking about it now."
Don Slime laughed. "You're quite open-minded."
"If it's a blessing, it won't be a disaster. If it's a disaster, you can't avoid it. There's no use thinking about it now. We can research it later when we travel to universes specialized in soul training," Setsuna shrugged. "Or, do you have any methods for training the soul?"
Don Slime yawned. "Eat, sleep, sleep, eat. As long as you live long enough, your soul naturally becomes stronger."
Setsuna was speechless, 'That was the pig-farming strategy.'
"Fine, I won't count on you."
Setsuna sighed. The Naruto World did have the Spirit Transformation Technique, which involved the soul, but unfortunately, it also required hand seals.
This created a vicious cycle. To dispel the foreign energy, he needed soul-related abilities first. But to learn the Spirit Transformation Technique, he had to avoid the interference of the foreign energy with hand seals.
And while the Spirit Transformation Technique's hand seals are simple, nothing is simpler than the Transformation Technique u which requires only one seal.
…
At Might Guy's home, Guy was doing one-handed push-ups, thinking to himself, 'No good, I ate so much delicious food today. The guilt is too strong. I must double my training to make up for it.'
"Guy!" The voice arrived before the person.
Might Duy made a cool drift appear at the doorway, accompanied by a timely, highly raised thumb, "Today, your dad completed another mission! To celebrate my Youth taking another great step forward, let's go eat barbecue!"
"No need, Dad. Look what I brought back." Guy, who had been waiting for this moment, excitedly jumped up and pointed at the donburi on the table, shouting.
"Where did this come from?" Duy looked at it in shock. Just the sight of this donburi instantly made his mouth water.
"Setsuna-san invited us to a gathering today. I brought this back from the banquet," Guy said, then worried his father might misunderstand, added, "It wasn't just me. Everyone took a portion home. Setsuna-san said sharing is the true essence of delicious food."
Duy breathed a sigh of relief. He was genuinely worried Guy had done something rude.
"Dad, eat it quickly. I've already eaten. I ate three whole bowls!" Guy patted his round belly.
"Then I won't stand on ceremony." Duy sat down, scooped a mouthful of rice, and immediately burst into tears. "I've never eaten anything this delicious in my life! The blood of Youth in me is about to erupt!"
"I understand!" Guy deeply empathized. At the time, he wanted to eat while doing a handstand, but felt too embarrassed to disturb others.
Duy placed the bowl and chopsticks on the floor, doing one-handed push-ups while rewarding himself by wielding the chopsticks.
"Guy, your senior is always so good to you, teaching you unique training methods and giving us such delicious food. We should know how to repay kindness."
Guy sighed, "I think so too, but I have nothing to repay him with. If only I were a girl, I could offer myself in marriage."
Duy fell silent. It was hard for him to tell whether that would count as repayment or revenge.
"I've got it! Then let's pass on the Forbidden Jutsu we learned, the Eight Gates, to him!" Duy said confidently.
"Dad, wake up! You're just a Genin. How could you know a Forbidden Jutsu?" Guy looked at Duy with concern, worried he had lost his mind.
Duy was shocked. "Did I never tell you I know the Forbidden Jutsu Eight Gates?"
Guy shook his head woodenly.
"Haha, I thought I had already taught it to you." Duy laughed awkwardly, then straightened his expression. "But it's fine. We'll go find your senior together tomorrow. You can learn it alongside him then."
Although Guy was somewhat speechless, he quickly became excited. "Dad, is this Eight Gates really that powerful?"
"Of course! I, a mere Genin, practiced diligently every day for twenty years before finally mastering this one and only move!" Duy clenched his fist confidently. "This will be our power to smash through the dark clouds!"
