In fact, Shinsei's current Ninjutsu is already powerful enough.
Kekkei Genkai: Storm Release, derived from Water Release: Water Severing Wave Technique; Space-Time Ninjutsu: Flying Thunder God Storm Release: Severing Wave; Water Release: Kirin; Ninjutsu Without Hand Seals: Storm Sword.
This includes Sage Mode, Chakra Enhanced Strength Technique, and Storm Release Armor, all belonging to the human race.
In the Shinobi World, Ninjutsu is not ranked according to its power, but only by its difficulty, ranging from C-rank to S-rank.
Of course, in general, the difficulty and power of Ninjutsu are directly proportional.
If a Ninjutsu is extremely difficult to use but its power is insufficient, then that Ninjutsu will face obsolescence.
The Ninjutsu listed by Shinsei are all among the most powerful Ninjutsu in the Shinobi World.
These combined skills made him virtually invincible in the Shinobi World.
Unfortunately, it was only almost.
His opponent was no ordinary person either; he was Madara Uchiha, who, Hashirama Senju, quelled the chaos of the Warring States period.
The current Madara Uchiha also possesses the Rinnegan.
The enemy has become stronger than ever before, so our skills must also be upgraded accordingly.
Putting everything else aside, if the Ten-Tails were to be reunited, Kaguya, who was sealed in the moon, would inevitably be released as well.
Shinsei's Ninjutsu was utterly inadequate against the Progenitor of Chakra.
I'm not the Sage of Sage of Six Paths ' biological son, so no one will resurrect me or give me any cheat codes after I die.
He had no choice but to develop Ninjutsu on his own.
A person's combat strength is usually determined by the power of their Ninjutsu, strength, speed, and combat experience.
But there is a hidden key element: neural responses.
If your reflexes are slow enough, even the most powerful Ninjutsu won't hit you. And if you can't dodge other people's Ninjutsu, you'll just have to start over with a new character.
A prime example is the Fourth Hokage, Minato Namikaze. In terms of Ninjutsu power, the Rasengan is simply no match for any other Ninjutsu.
However, the Fourth Hokage made a name for himself in the Shinobi World with his Flying Thunder God and Rasengan, earning the title of the fastest Shinobi World — the Yellow Flash.
If he hadn't been so suicidal, it's unlikely anyone would have killed him.
Minato Namikaze's reflexes were indeed outrageous. Obito Mangekyō, who possessed the Obito Uchiha, already had greatly enhanced reflexes, but he was still easily defeated by Minato Namikaze.
Shinsei now possesses the Three-Tomoe Sharingan, and with the added stimulation of his body's cells from Lightning Release, he still can't match Minato Namikaze in terms of nerve reflexes.
Even Minato Namikaze, known in the Shinobi World for his lightning-fast reflexes, was easily overwhelmed by Madara Uchiha after Madara Uchiha transformed into Six Paths Madara Six Paths Madara.
Without superhuman speed and reflexes, one would be instantly killed when facing Six Paths Level enemy.
Therefore, Shinsei spared no effort in developing the Descent of the Thunder God Project, which could maintain high-speed neural reactions even in battles at the Six Paths Level.
However, this plan is very difficult. Even with the assistance of biocomputers, a large amount of computation is required from analyzing the transmission of neural signals to reconstructing them.
In addition, there is a newly developed Palm Thunder Ninjutsu.
This is a physical Ninjutsu developed to counter the Rinnegan's ability to absorb Ninjutsu.
Last time when dealing with Madara Uchiha, seeing that Susanoo that was hundreds of meters tall, I didn't reveal it to him, just to tickle it.
Its advantage lies entirely in its reliance on physical reactions; its power does not depend on Chakra, but rather on the compression ratio of water.
Theoretically speaking, even if Otsutsuki Kaguya were hit by a Palm Thunder, she would be severely injured.
But the prerequisite is that it can actually be hit. If Otsutsuki Kaguya could really be killed by a Palm Thunder, Shinsei would be laughing in his sleep.
In addition, it is necessary to make use of one's vast mental energy.
Thanks to Shinsei's long period of meditation and cultivation, as well as his identity as a transmigrator, he possesses spiritual power that is difficult for ordinary people to attain.
This kind of spiritual power is the mark of an unparalleled genius in using Yin Release. In particular, he often saw Nine-Tails use his tails so skillfully that he couldn't help but feel envious.
Yin Release can create form without being visible. Once you master Yin Release, Shinsei can manipulate the Chakra within your body like a limb.
Moreover, in battles at the Six Paths Level, ordinary Ninjutsu becomes ineffective; only Senjutsu and Yin-Yang Release remain useful.
He had already mastered the Senjutsu, so he couldn't let go of the Yin-Yang Release technique either.
I tried to trick Madara Uchiha into teaching me the Yin-Yang Release technique, but although Madara was arrogant, he didn't actually do anything stupid.
There are still some ninja clans in Konoha who possess some knowledge of Yin-Yang Release.
For example, the Yamanaka Clan, the Nara Clan, and the Akimichi Clan, who possess the Yang Release.
Prying into the secrets of ninja clans is a major taboo in the Shinobi World. However, Shikamaru and Choji are both on good terms with him, so exchanging some Ninjutsu knowledge might be successful.
As for the Yamanaka Clan, with Ino around, she might just teach him all of their clan's secret techniques if he asked.
I haven't had the time before, but now that Sasuke getting used to the power of the Cursed Seal, I can try to exchange them.
Shinsei didn't actually need their family's secret techniques; he just wanted to know about Yin-Yang Release techniques.
A true teaching can be conveyed in a single sentence, while false teachings fill countless volumes. Without this relevant knowledge, relying solely on imagination, Shinsei is likely to take many detours.
He put down the pen, used Chakra to shred the blank paper covered in writing, and threw it into the trash can.
He habitually gripped the stone on the table in his hand.
Since acquiring the Light-Weight Rock Technique, Shinsei has been trying to sense the so-called Earth Release gravity properties.
Unfortunately, this feeling is like fishing in the ocean, relying solely on luck. Perhaps Ōnoki possesses secret knowledge passed down through generations, but it's impossible for him to tell Shinsei.
He stood up, walked to his bedside, and prepared to sit down and meditate. He casually tossed the stone in his hand and subconsciously used Earth Release Chakra.
Thump, thump, thump, the stone landed lightly on the table, making a crisp sound.
But the sound struck Shinsei like a bolt from the blue.
He was all too familiar with the sound of the stone landing on the table. But judging from the force with which he had thrown it, the sound was much softer.
In other words, the stone did not reach its own weight!
He hurried over, grabbed the stone, imbued it with Chakra, and tossed it into the air.
The stone landed steadily in his hand.
Shinsei's Sharingan had already quietly activated, allowing him to clearly see the trajectory of the stone as it fell into his hand.
The stone has indeed been reduced in weight!
A feeling of joy welled up in his heart.
I've mastered the Light-Weight Rock Technique!
