Chapter 69: Yin-Yang Release.

"Yin-Yang Release!"

Seeing Fugaku's inquiring eyes, Toshirou answered firmly, without a trace of hesitation in his tone.

In fact, before going through those scrolls, he had already made a secret decision. It would either be the Flying Thunder God Technique or Yin-Yang Release.

There's no need to elaborate on the Flying Thunder God Technique; for someone like him, who prioritizes survival, it is incredibly useful.

Whether it can be used in actual combat is another matter; at the very least, in terms of escape, no one should be able to stop him.

With that, the Third Shinobi World War, the subsequent Nine-Tails' attack, and the Night of the Uchiha Massacre could all be easily resolved.

He wasn't considering what kind of merits he could achieve in the Third Shinobi War, or to save the clan for glory. The very least he wanted was to guarantee his own survival.

He didn't possess the selfless spirit of the Fourth Hokage. To die for the village was already quite something, let alone offering up his own son.

If there was any sign of trouble, he'd escape first. As for whether he could actually learn the technique, that was still up for discussion.

Expecting him to master it like Minato Namikaze or Tobirama Senju, turning it into his signature skill, seemed quite challenging.

However, in terms of using it purely for escape, he had about a 50-60% chance.

After all, Shisui, Genma Shiranui, and Iwashi Tatami, who once served as the Fourth Hokage's guards, could use the "Flying Thunder Needle" technique to carry the Fifth Mizukage for spatial transfers.

This indicates that space-time attributes are not exclusive to Tobirama Senju and Minato Namikaze. As someone from another world, he still had a glimmer of hope.

In recent years, to prepare ahead, he learned a lot of theoretical knowledge. Not just the theories taught at the Ninja Academy, but he also borrowed many books from Konoha's library.

Against an average chunin, he could easily hold his own in this regard. As he became a ninja, his access to books would further increase, hence his theoretical knowledge would continue to improve.

He couldn't believe that, as a university graduate, he couldn't master a mere jutsu. He didn't need to be like Minato or the Second Hokage, launching a Flying Thunder God behind someone's back to deliver a sneak attack.

He only needed to be able to use it for escaping, even if it required hand signs; he could accept that.

If he couldn't meet the standard, removing some "non-essential" functionalities from the Flying Thunder God Technique wouldn't be unbearable.

By breaking down a major task or process into smaller parts, he could tackle each segment individually. He didn't need to master the entire thing, just the parts he needed.

This was an experience born from his prior life's different experiences.

As for Yin-Yang Release, starting with Yin Release, he knew that Sharingan could be considered an external manifestation of Yin Release.

If he awakens the Sharingan in the future, Yin Release would make developing the Sharingan much easier. The Mangekyo Sharingan or Eternal Mangekyo Sharingan could be considered later; it was too early now.

To put it simply, Genjutsu uses chakra to inject one's mental energy into another person's mind.

By interfering with the opponent's brain, their body could be controlled, leading them to become a puppet.

Yin Release is about creating form from nothingness, materializing imagination into reality. This is the best training method for mental strength.

As for Yang Release, aside from enhancing medical ninjutsu, it boosts one's strength, stamina, recovery rate, and chakra reserves, which are invaluable.

While he might not heal as instantly as Hashirama, or use the Strength of a Hundred Seal like Tsunade, it should at least significantly improve his recovery abilities.

The same goes for stamina and chakra reserves. It's often said, 'without Yin, Yang can't grow; without Yang, Yin can't thrive.' These principles were ingrained in his mind.

Moreover, training in Yang Release might also have another significant aspect. He suspected that sage arts and chakra reserves, as well as one's achievements in Yang Release, might be related.

Otherwise, how could one explain the perfect sage modes of Hashirama Senju and Naruto Uzumaki?

Hashirama's sage mode, even in his 30s, only showed the sage markings, which was acceptable.

But Uzumaki Naruto, at a mere 16 years old, had barely any frog-like traits except for the eye markings during sage mode.

In contrast to Jiraiya and Kabuto Yakushi, the former assumed some frog features, while the latter transformed somewhat into a snake or dragon.

As for achieving the combined power of Yin and Yang, he wasn't at that stage yet to crave such power.

Fugaku was undeniably surprised by Toshirou's choice. Children at this age usually select an A-rank or S-rank jutsu with great power.

Others, aiming higher, might choose Genjutsu or more complex secret techniques. Those with strong clan pride might opt for fire release scrolls.

The majority would try to peek into those great sharingan secret scrolls to find the secret or shortcut for awakening the Sharingan.

Choosing Yin-Yang Release was incredibly rare. The main reason is that most haven't even heard of such concepts.

Even those well-informed knew its training difficulty, making them hesitate.

Whether it's Yin or Yang Release, the mental and physical strengths they represent are inherent in every human. However, developing and utilizing them is immensely challenging.

This rarity of Genjutsu and medical ninjas in the ranks corroborates this, requiring both talent and incredible willpower.

Fugaku himself had only minor achievements in Yin Release.
