Even if Ginkaku and Kinkaku possessed Nine-Tailed Chakra, significantly boosting their strength, it would be impossible for them to keep Senju Tobirama there.
Given Senju Tobirama's power, if he wanted to leave, no one could stop him.
Something unknown must have happened that prevented Senju Tobirama from using Flying Thunder God to escape.
"What exactly happened?" Renye frowned, lost in thought.
The reason for that Old Man's death was like a mystery.
He clearly had Flying Thunder God, yet he was forcibly kept by Ginkaku and Kinkaku.
Renye thought for a long time but couldn't figure it out, finally giving up on the matter.
Anyway, that Old Man isn't dead yet, so when the time comes, he just needs to be reminded to use Flying Thunder God to run.
After all, Ginkaku and Kinkaku aren't strong enough to instantly kill Senju Tobirama.
If he can't win, he can just run.
With him around, Senju Tobirama won't die.
Thinking this, Renye continued to study Fire Release Ninjutsu.
The Ninjutsu he was currently learning was called 【Fire Release: Flaming Vortex Blast Formation】.
After clapping his hands, a circular flame vortex erupts from the ground, the flames spiral upwards, forming a pillar of fire in the air, and the high-temperature airflow inside creates negative pressure, drawing in and incinerating surrounding objects.
It's suitable for battlefield containment or area-of-effect attacks.
The only drawback of this Jutsu is its high Chakra consumption.
However, this amount of Chakra is negligible for Renye; his Chakra reserves are immense, far exceeding those of his Uchiha clansmen his age.
He didn't know the reason for his body's changes.
Renye was like an anomaly; his physical prowess far surpassed both Uchiha and Senju.
"Could it be... I'm the crystallization of Uchiha and Senju love?"
It seemed like only this situation could explain it.
Parents from Senju and Uchiha caused his body to undergo an atavistic change.
However, Renye quickly dismissed this unrealistic idea.
The war between Uchiha and Senju lasted for a thousand years; both sides wished to kill each other, so how could they be together?
Even if they were together, if their families found out, they would definitely be drowned in a pig cage.
In that case, Renye would have had no possibility of being born.
Even if he was born, he would have been thrown to his death...
Although he didn't know the reason, this was a good thing for Renye.
No one would complain about being too strong; they would only complain about not being strong enough.
...
The bright moon hung in the sky.
Renye was still training diligently in the training ground.
Just then, Senju Tobirama walked into the courtyard, and upon seeing Renye still training, he couldn't help but frown.
"It's so late, and you're still not sleeping?"
Hearing this, Renye realized it was already very late.
He quickly stopped training and said, "I'm going to sleep right away."
That Old Man was fine in other aspects, but when it came to sleeping, his attitude was very firm.
He said that Renye was still growing and absolutely couldn't stay up late.
So, Renye had never stayed up late all these years.
Even when on missions, he would stop and rest when it was time.
Senju Tobirama said nothing more.
Dealing with matters these past two days had exhausted him; he hadn't rested well.
He felt a bit regretful, thinking he couldn't research this kid for a while.
Now that his older brother had passed away, various countries were eyeing the Land of Fire covetously, and war could break out at any time.
Senju Tobirama needed to maintain his spirit to deal with the impending crisis, so he naturally had no time for research.
"Drink your milk and rest early; I'm going back to sleep."
Renye watched as Senju Tobirama prepared to return to his room and quickly called out to him.
"Uncle, wait a moment..."
Senju Tobirama heard him, stopped, turned around, and asked,
"Kid, is there anything else?"
"Uncle, I want to learn the Flying Thunder God Technique!" Renye looked at Senju Tobirama.
He had wanted to learn this Ninjutsu for a long time, but he hadn't brought it up because he felt his relationship with Senju Tobirama wasn't good enough, fearing that Old Man wouldn't be willing to teach him.
If he brought it up and the other party refused to teach him, wouldn't that be awkward?
But now it was different; that Old Man had eaten the food he cooked.
As the old saying goes, 'He who eats another's food is beholden to him, and he who takes another's money is beholden to him.'
Senju Tobirama couldn't refuse to teach him now!
Old Man, this is not up to you, hehehe...
Did he really think his years as a chef were for nothing?
Senju Tobirama was slightly startled by his words, looking at Renye with some surprise.
"You want to learn the Flying Thunder God Technique?"
"That's right, I want to learn it." Renye's eyes were firm.
He was determined to master such a heaven-defying Ninjutsu as Flying Thunder God!
It was practically a god-tier escape Ninjutsu!
Once he learned it, virtually no one in the Ninja World would be able to kill him.
Senju Tobirama's face showed hesitation; the idea of teaching Renye Flying Thunder God had occurred to him a long time ago.
It was just that he felt that with Renye's academic performance, he simply wouldn't be able to grasp the complex principles of space Ninjutsu and spatial coordinates.
After all, the Flying Thunder God is extremely difficult to learn, and he didn't believe someone who scored five points in cultural studies could learn it.
Senju Tobirama believed that this kid simply couldn't understand complex Ninjutsu principles...
Since Renye brought it up himself, he wouldn't refuse.
As for whether he could learn it, that would be up to Renye himself.
However, given the difficulty of learning Flying Thunder God, Senju Tobirama didn't believe Renye could learn it.
Even if he learned it, it would be very difficult to use, perhaps only successfully teleporting once out of dozens of attempts.
It was even possible he might not be able to teleport even once.
"If you want to learn it, then I'll teach you."
Senju Tobirama had no intention of discouraging Renye; he felt it wasn't necessary.
When he couldn't learn it, he would give up on his own.
Seeing that Old Man agree, Renye's lips curved slightly upward.
He was already fantasizing about himself mastering Flying Thunder God and wreaking havoc in the Ninja World...
His low-tier Flying Thunder God Slash was finally going to become a true Flying Thunder God Slash!
He'd be taking out opponents one by one then.
Just as Renye was lost in his fantasy, Senju Tobirama entered the study and came out holding a stack of books.
"Uncle, why are you carrying so many books?" Renye was a bit puzzled.
"Oh, you mean these?" Senju Tobirama said, "These are all knowledge that must be mastered before learning Flying Thunder God."
As he spoke, he handed the books to Renye.
"This one is a theoretical book on space-time Ninjutsu."
"This one is a book on understanding spatial structures."
"This one is about the interaction between Chakra and space."
Renye looked at the stack of books in his hands and instantly froze.
He knew learning Flying Thunder God was complex, but he didn't expect it to be this complex!
Damn it, no one told him he needed to read so many books before!
"Uncle, do I have to read all these books?" Renye swallowed.
"Not just simply read them, but also master them," Senju Tobirama explained.
"These books are all to lay the foundation for learning the Flying Thunder God Technique; you must learn them."
Renye: "..."
