Naruto: The Strongest Medical Ninja in the Shinobi World

Chapter 114 Cultivation, Flying Thunder God

Chapter 105 Cultivation, Flying Thunder God

Back at the Senju residence, Shizune had already left.

At her age, she doesn't need to bear such a heavy burden today.

Yesterday, Xingyuan Qianshuo informed the three students that they should practice or take on missions from Monday to Saturday each week, and rest on Sunday.

Jingyin then arranged to meet Lin today to inform her about the "graduation" arrangements.

At this moment, Hoshino Senjutsu was already eager to go to Tobirama's Ninjutsu Library to browse and study.

Tsunade saw through his thoughts at a glance and went with him.

Stepping into that seemingly ordinary room, Xingyuan Qianshuo bit his finger and pressed it into the ground, forming a hand seal.

The underground entrance slowly emerged, and the two stepped into the passage one after the other.

"Chisaku, which ninjutsu do you plan to learn first?" Tsunade asked as they walked.

"Currently, I am mainly studying Water Release, Wind Release, and Sealing Techniques, and I am also trying out Illusion Techniques. I still need to delve deeper into these four types."

Xingyuan Qianshuo had already made plans. After a moment's thought, he continued, "I also need to study swordsmanship and physical techniques. In addition, I need to choose suitable techniques from secret and forbidden arts to practice—especially the Flying Thunder God Technique, which I've been eyeing for a long time."

That being said, he was actually more interested in the "research and conjecture" materials left by Tobirama.

Secret techniques and forbidden techniques, though powerful, are known; but those research records truly embody this research-oriented ninja's understanding of power and the world.

"You know, don't be disappointed when you see those harsh training conditions later," Tsunade chuckled.

She once admired the Flying Thunder God technique, but after reading about it, she gave up.

"However, Chisaku, your chakra reserves are considerable, so you could sign the Rashomon summoning contract first," Tsunade suggested.

Several enormous, ghostly gates flashed through Xingyuan Qianshuo's mind. Feigning ignorance, he asked, "What's the story behind Rashomon?"

"Rashomon can summon giant gates from other dimensions for defense, up to five layers. If you don't have enough chakra, you might only be able to summon one layer," Tsunade explained. "But the demon face on that gate looks uncomfortable, so I didn't sign it."

Xingyuan Qianshuo understood and continued, "Did Lord Tobirama record the origins of Rashomon?"

"Yes, my second grandfather speculated that it was the gate between life and death leading to the Yellow Springs in ancient times."

Tsunade recalled, "He believed that the power wielded by the ancient strongmen was different from chakra; they could even control the Underworld and the Pure Land, and that there existed what were called gods."

"However, these are all just ancient legends. If we trace them back, it would be at least several thousand years ago."

Xingyuan Qianshuo nodded without offering any explanation.

These may seem like legends, but they are not entirely without precedent.

According to the original story, before the arrival of the Otsutsuki, this planet did indeed have its own powerful inhabitants—whether they were called "gods" or not is perhaps just a matter of different names.

Before the divine tree plundered the energy of nature and life, this world must have been full of energy, and it is not surprising that it gave birth to strong beings.

Referring to the three sacred sites: they exist solely from remnants of other dimensions, yet they can utilize natural energy, making them not only powerful but also long-lived.

Consider the enormous body of a slug and the massive island tortoise of Cloud Village—how could such a behemoth survive without abundant energy and a vast space?

Another clear example is the inherent ability of the Mangekyou Sharingan, "Susanoo".

All kaleidoscopes can perform this technique, which makes it hard not to wonder: Did such a god-level powerhouse ever exist?

This ability is not something the Otsutsuki clan is born with; rather, it is more like the power that the Divine Tree failed to fully digest after absorbing the energy of this planet.

This power resided within Hagoromo Otsutsuki, and after being guided and activated by Gamamaru, it transformed into the Sharingan, leading to his break with Kaguya Otsutsuki.

In a sense, this is a counterattack by this world against the Otsutsuki.

There are many other similar pieces of evidence:

The Grim Reaper who seals away the corpse demon, the King of Hell who is reborn through reincarnation, even the sealing techniques of the Myojinmon and Uzumaki clans, and the Immovable King who sings like a toad...

Cixian, this ancient monk, and so on.

After awakening and traversing his memories, Xingyuan Qianshuo often pondered these questions.

Now, he also wants to know how the powerful Tobirama Senju thought or answered these questions, and whether he had obtained any records from the three holy lands.

After all, the most direct answerer to such questions is none other than the long-lived sages of sacred lands—especially Gamamaru of Mount Myōboku, the great toad sage with a doctoral cap and a vast collection of books.

Hoshino Senju decided to find some time to review Tobirama's research records.

If the slug fairy's words are not found, then I will ask the slug fairy for guidance on another day.

"So, where should we start?" Tsunade asked.

"While you're here, let's look at the techniques that require your permission first," Hoshino Senju said thoughtfully. "Starting with the Flying Thunder God Technique, I want to see exactly what conditions it requires."

"I knew it."

Tsunade smiled and walked to the middle bookshelf, searching briefly before taking out a volume: "Here, take a look."

She handed over the reel, a smile of anticipation playing on her lips.

Xingyuan Qianshuo took it, slowly unfolded it on the wooden table, and began to read it carefully.

A few minutes later, he let out a long sigh of relief and looked up to meet Tsunade's teasing gaze.

"So, Qian Shuo, do you think you can master it?"

Hoshino Senjutsu did not answer directly, but only sighed: "Lord Tobirama's understanding of summoning techniques is truly profound—as is the fusion of Yin Release power and sealing techniques. Only by delving into its essence can one create such a space-time ninjutsu."

99

"Yes," Tsunade agreed.

The Flying Thunder God Technique is essentially a psychic technique, a high-level "reverse psychic technique" or "self-psychic technique".

The principle is easy to understand, but it is extremely difficult to apply in practice.

This S-rank ninjutsu has five key elements: technique mark, technique perception, spatial and temporal talent, neural reaction speed, and massive chakra and precise control.

In terms of technique markings, Tobirama's Flying Thunder God mark is a special pattern, while Minato's is the four characters "Sword of Endurance and Love".

This mark is a high-level application of Yin Release, a "form" that materializes spiritual energy, transforming one's own will and chakra into spatial coordinates.

Such marks can persist for a long time, and are difficult to remove by conventional means except for higher-level Yin Escape or Yin-Yang Escape techniques.

The stable Yin Release mark resonates with one's own chakra, enabling both long-distance perception and spatial connection.

Tobirama's patterns blend Yin Release and sealing techniques, while Minato's handwriting may lean more towards pure Yin Release power.

The remaining key points are relatively easy to understand:

Perception and spatial and temporal innate abilities are essential prerequisites for cultivation;

Neural reflexes and chakra are the two key requirements for improving combat effectiveness.

Without extraordinary reaction speed, the Flying Thunder God Technique can only be used for teleportation and is difficult to form a combat force.

Xingyuan Qianshuo thought to himself:

Currently, chakra perception is the biggest weakness; chakra quantity and control are the most outstanding; nerve reaction has improved once, but is still not as good as Minato; space-time talent is above average; Yin Release power is already excellent after the Sharingan and mental power are improved.

Therefore, he can first learn to create spell marks, while simultaneously trying to improve his perception.

He approached the Flying Thunder God Technique with a tentative attitude, hoping to succeed if he could, but if not, he would have to wait for a reward from Minato.

In the future, this study and practice can serve as a cover for external affairs.

After thinking it over, he said, "I plan to first learn how to make the Flying Thunder God Technique, and see if I can learn Lord Tobirama's sensory ninjutsu."

Tsunade nodded: "It's worth a try. If it really doesn't work, there's no need to waste too much effort."

"clear."

She paused for a moment, recalling her past attempts: "Although I know the Golden Binding Technique, my Yin Escape talent is far inferior to Yang Escape, and I got stuck at the first step. In addition, my perception is average, my space-time talent is mediocre, and my reaction speed is average, so I gave up directly back then."

Xingyuan Qianshuo couldn't help but smile; Tsunade's "self-deprecation" was rather rare.

However, talent is something that you either have or you don't.

Unless one researches cell transplantation like Orochimaru or practices resurrection, it is difficult to defy fate.

Fortunately, he possessed a system cheat code—anything was possible.

Under Tsunade's guidance, he found the scroll of "Earth ley line perception technique" and "Record of perception ninjutsu" and began to read them carefully.

Tsunade didn't leave either, but instead picked up a large book, "A Study on the Essence of Yang Release: Life Formation," and read it quietly.

She usually only skimmed through the books in the underground space, and only selected them when needed.

In recent years, he has been depressed and has come here to practice even less.

This set of books, "Yang Dun," consists of three volumes. She had read it briefly before, but now that she understands it more deeply, she has decided to study it in detail again.
