Simultaneous travel: I am proving the great way in the heavens

Returning from the Tsukuyomi space, Tsunade looked at Luo Fu with a complex expression, unable to speak for a long time.

With Tsunade's strength, and the fact that Luo Fu didn't intend to harm her with genjutsu within the Tsukuyomi space,

logically, Tsunade shouldn't have been so affected, remaining lost in thought for so long.

What truly caused Tsunade to react this way were Luo Fu's seemingly logically consistent words within the genjutsu space.

Especially at the end, when Luo Fu confidently declared that he could produce evidence that would convince Tsunade.

This made Tsunade even more hesitant.

Luo Fu didn't urge her, but thoughtfully picked up the wine jug and refilled the empty wine cup in front of Tsunade.

While pouring the wine, Luo Fu said, "Tsunade Senju, I do have evidence that can prove everything, but Tsunade, are you sure you can accept the truth and reality?"

Snapping out of her daze, Tsunade gave a wry smile, raised the wine cup in front of her, and drank it all in one gulp.

"I don't need you to remind me, and besides, I've seen everything. Come on, what kind of evidence are you going to produce to make me believe everything you've said?"

Unexpectedly, Luo Fu stretched out both hands, one hand holding a sharp kunai. In Tsunade's astonished gaze, the kunai instantly slashed across his finger.

A few drops of blood instantly flowed down from his fingertip.

Tsunade said with a strange expression, "You don't really believe I have hemophobia, do you? Trying to scare me with blood?"

"How could someone who ushered in a new era of medical ninjutsu have a ridiculous fear of blood?" Luo Fu shook his head with a smile, and brought the few drops of blood to Tsunade's face, saying, "I don't know if you know, but your grandfather, Hashirama Senju, had an extremely strong physique, and even his cells had unparalleled invasiveness."

Her expression turning somewhat unpleasant, Tsunade said, "You wouldn't be like that old monkey and Orochimaru, desecrating my grandfather's corpse, would you?"

"Of course not, I've only heard about it." Luo Fu shook his head, explaining, "I'm not the same as Hashirama Senju. My blood and his cells have the same effect in different ways. If you drink my blood, you'll find that those seemingly absurd things I said before are the truth of everything."

"You want me to drink your blood?" Tsunade frowned, staring at Luo Fu, as if confirming whether he was joking or being serious.

Nodding affirmatively, Luo Fu said, "That's right. Aren't you asking for evidence? No evidence is better than drinking a few drops of blood and experiencing it yourself."

Taking a deep breath, Tsunade hesitated for a moment, then reached out and took the few drops of blood from Luo Fu's hand.

Enveloped in chakra, the blood, though liquid, looked like crimson gems.

Looking at Luo Fu again, Tsunade hardened her heart, brought the blood to her lips, and with a gentle sip, instantly sucked the blood into her mouth, swallowing it with a 'gulp'.

"I've already…"

Her voice abruptly stopped, Tsunade looked at Luo Fu in horror. As the few drops of blood entered her stomach, Tsunade clearly felt her chakra uncontrollably rioting.

For ordinary ninjas, a chakra riot might at most be unsettling, but it was different for Tsunade.

The basic requirement for entry is the subtle manipulation of every single bit of chakra.

Yet, Luo Fu had only used a few drops of blood to completely disrupt the chakra within Tsunade's body, causing it to riot.

Before Tsunade could regain control of her chakra, her eyes rolled back and she collapsed onto the wine table, entering a transformation.

So far, Luo Fu had given his blood to three people in the ninja world, transforming them into members of his own system.

Yekura was seriously injured and dying at the time, and without understanding medical ninjutsu, Luo Fu completely treated her as a dead horse to be revived. By chance, he completed Yekura's transformation.

As for Xiao Nan, after drinking Luo Fu's blood, she only uttered one syllable before directly falling into a coma, beginning the process of life transformation.

Only Tsunade, whether due to her own powerful chakra control or because she was the only bloodline descendant of the Senju clan,

she managed to say a few words completely before falling into a coma.

Tsunade's sudden collapse onto the table caused Kato Shizune, who had been standing at the entrance of the tavern, preventing others from entering and explaining Tsunade's earlier outburst, to become vigilant.

In her urgency, Kato Shizune even directly used the Body Flicker Technique to arrive in front of Tsunade.

Before Kato Shizune could examine Tsunade's condition, Luo Fu preemptively intervened, stopping Shizune. He said, "Don't move, don't worry, Lady Tsunade is fine. She has just entered a life transformation and will wake up soon. Don't forget, although I am a member of the Uchiha clan, the feud between the Uchiha and Senju clans is completely a thing of decades ago. As a ninja of Konoha, I have no reason to attack Tsunade, do I?"

With a conflicted look on her small face, Kato Shizune glanced at Luo Fu and said, "Senior Luo Fu, I can't let Lady Tsunade take any risks! I'm sorry, but please step aside."

"Sigh! You really are stubborn. In that case, I can only ask you to wait a moment!!"

The patterns of the Mangekyo instantly appeared in Luo Fu's eyes.

Kato Shizune instantly fell into the genjutsu space.

This wasn't a Mangekyo genjutsu, but a genjutsu simply cast with the Sharingan.

The Sharingan itself has an extremely strong enhancing effect on genjutsu. Even in the three-tomoe state, genjutsu can easily immerse a jonin in it.

Not to mention Luo Fu's Mangekyo state at this moment.

Kato Shizune didn't even struggle for a moment before becoming dazed in place.

Compared to Xiao Nan's previous transformation, this time Tsunade's transformation process was much longer. Although it certainly couldn't compare to Yekura's severely injured and dying state at the time,

by the time Tsunade had completely finished her transformation, it was already the next day.

The moment her consciousness returned, Tsunade suddenly became alert, subconsciously checking her surroundings.

It was also at this time that Tsunade was horrified to discover that the amount of chakra within her body had suddenly multiplied several times.

You should know that Tsunade's situation is different from ordinary ninjas. She has the Yin Seal on her forehead that can maintain her youth forever.

Ordinary ninjas refine and use chakra at any time, but Tsunade developed the Yin Seal to seal the chakra she refined into her forehead in any situation, taking it out whenever needed.

In this situation, the amount of chakra multiplied several times, which is equivalent to a normal ninja's chakra being ten times, or even dozens of times, greater.

What made Tsunade even more unbelievable was that her chakra had become as agile as an extension of her consciousness, moving at will.

Whether it was precise or violent manipulation, she could achieve a mysterious and wonderful state of doing whatever she wanted.

What truly made Tsunade change her expression was that she felt that her chakra had given birth to another inexplicable Yang Release life force.

Tsunade had only felt this kind of feeling on the cells of her grandfather, Hashirama Senju.

With a sudden inspiration, Tsunade subconsciously stretched out a hand, and a tender green sapling appeared out of nowhere in her palm, slowly and gracefully unfolding its branches and growing.

"Wood… Wood Release!!" Tsunade blurted out.

In the ninja world, the most powerful ninjutsu recognized by everyone is undoubtedly Hashirama Senju's Wood Release.

After all, that was the ninjutsu that pacified the warring states period.

Although it was only a kekkei genkai, even a kekkei tota was far inferior to Wood Release.

From the heavy price Konoha paid to reproduce Wood Release, it is not difficult to feel that the powerful cognition of Wood Release has almost penetrated into the depths of the hearts of Konoha ninjas, and even the ninjas of the entire ninja world.

As a member of the Senju clan, after Hashirama Senju and Nawaki Senju, no one was able to awaken Wood Release, which was definitely a regret for the Senju clan, even Tsunade was no exception.

But Tsunade never dreamed that the Wood Release she had been looking forward to since childhood would appear on her at this time.

Under the impact of great surprise, Tsunade even subconsciously ignored her surroundings.

She couldn't wait to sit up and stride to the open space, quickly recalling the hand seals of Wood Release in her mind.

Just as Tsunade was about to test her awakened Wood Release, inexplicably, a premonition that even she herself couldn't believe welled up in her heart.

It seemed that her Wood Release was just like the description of her grandfather, Tobirama Senju, about his brother.

In Hashirama Senju's hands, the powerful Wood Release didn't even need hand seals. He could easily perform any Wood Release by simply clapping his hands.

Of course, Tsunade also knew that such words were actually Second Hokage Tobirama Senju's jealousy towards his elder brother's incomprehensibly powerful talent.

In fact, Wood Release requires hand seals, and even Hashirama Senju habitually forms the Snake seal when using Wood Release.

Under a strange impulse in her mind.

Tsunade, as if blessed by the heavens, clasped her hands together in front of her, forming the Snake seal.

"Wood Release! Adamantine Summoning: Wood!"

As Tsunade's voice fell, a sturdy tree instantly sprouted from the ground.

"Could it… could it really be true?" Tsunade widened her eyes, looking at the Wood Release she had personally summoned, and muttered to herself.

"Lady Tsunade!!"

Just as Tsunade was feeling inexplicably emotional, a familiar voice suddenly came from not far away.

Looking in the direction of the voice, Shizune Katō was rushing towards her at a very fast speed.

"Shizune." Tsunade excitedly couldn't wait to share her changes with someone. "Did you see it? Did you see it? I awakened Wood Release, I awakened the same Wood Release as Grandpa and Nawaki."

Although indeed shocked by Tsunade's use of Wood Release, Shizune Katō was more concerned about Tsunade's physical condition at the moment.

Earlier, at the small tavern, Tsunade had suddenly fainted for no reason, and she had fallen into Rōfu's genjutsu.

By the time she woke up, she had already appeared in the forest some distance outside the town.

She saw that Tsunade was by her side, and indeed seemed to be in a state of awakening a bloodline limit. Although very worried, Shizune Katō did not dare to disturb her easily.

In the ninja world, some special bloodline limit awakenings are indeed like Tsunade's situation at the time, and, for some special bloodline limits, the most taboo thing during awakening is being disturbed by others. Carelessly, it can even cause all sorts of irreparable situations.

But under normal circumstances, bloodline limit awakenings are never like Tsunade Senju's, where someone in their fifties suddenly awakens a bloodline limit.

Now seeing that Tsunade was not only really safe and sound, but even Wood Release had miraculously awakened, Shizune Katō knew that what Uchiha Rōfu said was indeed true.

Fortunately, she didn't rashly interrupt, otherwise, wouldn't it have made Lady Tsunade regret it for the rest of her life?

"Congratulations, Lady Tsunade. You have awakened the same Wood Release as the First Hokage." Shizune Katō was overjoyed, even more excited than Tsunade herself.

Calming down, Tsunade finally thought of the source that allowed her to awaken Wood Release, Uchiha Rōfu.

Tsunade had also had an impression of Rōfu before.

Who told Rōfu to approach Katō Dan just before Tsunade and Katō Dan's relationship gradually became closer?

When she was with Katō Dan, Tsunade never heard Katō Dan lament about Rōfu, this member of the Uchiha clan, and his dedication and regret for the Spiritualization Technique.

It's just a pity that Konoha had not been established for many years at that time, and Tsunade was exposed to too many ideas instilled in her by the Senju elders at the time. She had an instinctive resistance and distrust towards the Uchiha clan.

"Where is he?" Tsunade asked Shizune Katō urgently, "I mean, where is that Uchiha kid?"

At this moment, after the surprise of awakening Wood Release, Tsunade felt an unprecedented sense of panic and unease in her heart.

Since Rōfu could easily rely on a few drops of blood to awaken her Wood Release, then everything he told in the genjutsu, could it also be true?

The Sage of Six Paths, the Sage of Six Paths' younger brother, that terrifying goddess whose shadow alone seemed to envelop the entire world…

Just recalling what she saw and heard in the genjutsu space, Tsunade's heart couldn't help but surge with panic and unease.

"Lady Tsunade, please rest assured, that guy went to the neighboring town and will be back soon…"

Before Shizune Katō could finish speaking, a spatial vortex instantly appeared not far from the two of them.

Wearing close-fitting clothes, completely unlike a ninja, and even more like a nobleman, Rōfu leisurely appeared in front of the two of them.

As soon as she saw Rōfu, Tsunade couldn't wait to go forward and grab Rōfu's collar, pulling him towards the depths of the forest.

From afar, Tsunade's voice instructing Shizune Katō came.

"Shizune, don't follow me, just wait for me here."

Looking at the backs of Rōfu and Tsunade, Shizune Katō's expression couldn't help but become a little complicated.

Since the end of the Second Shinobi World War, Shizune Katō had been taken out of the village by Tsunade before graduating from the ninja academy.

For so many years, although Shizune Katō is now taking care of Tsunade, in fact, Shizune Katō, who was just a little loli at the beginning, was able to grow up smoothly thanks to Tsunade's care.

Following Tsunade for so long, Shizune Katō has gradually understood the reason why Tsunade left Konoha.

She is naturally full of gratitude towards Tsunade.

Don't forget that Katō Dan's death itself was full of doubts, and it was even very likely that the Konoha high-level officials directly took action.

And among the Katō clan, besides herself who was taken out of Konoha by Tsunade, there is no one else left.

On the surface, the Katō clan did indeed sacrifice too much in the war.

But the ninja clan, which was able to pass on for so long in the chaotic Warring States Period, only had Shizune Katō as the only survivor after joining Konoha, which was established for only a few decades.

Unless she is hopelessly stupid, it is impossible for Shizune Katō not to notice the darkness of Konoha.

It is precisely because of this that Shizune Katō is becoming more and more infatuated with Tsunade, and even has a faint feeling of sympathy.

Shizune Katō naturally sees clearly that Tsunade has been unable to get over the deaths of her younger brother Nawaki Senju and her uncle Katō Dan for so many years.

And now, in Shizune Katō's opinion, Tsunade seems to have found her happiness, even if this guy is a member of the Uchiha clan who is much younger than Tsunade, and even almost became her uncle's disciple back then.

Looking at the direction of Rōfu and Tsunade who had disappeared into the depths of the forest, Shizune Katō murmured, "Lady Tsunade."

Deep in the forest.

After arriving at a secluded enough place.

Tsunade let go of Rōfu, and then used her own ninjutsu to sense the surroundings, confirming that it was absolutely safe, and then she said in a deep voice, "Tell me, what exactly is going on here?"

"Do you know about cattle and sheep being raised in captivity?" Rōfu said meaningfully, "I originally thought that you, who developed the Strength of a Hundred Seal, should be able to perceive the specialness of chakra, but the facts prove that I seem to have overestimated you a bit. Although you do have unimaginable talent in medical ninjutsu, this talent is only limited to the level of medical ninjutsu. You seem to have deliberately ignored the cognition of the essence of chakra."

"Don't beat around the bush with me." Tsunade frowned in dissatisfaction and said, "Just say what you discovered? Also, are you using your weird techniques again to manipulate my emotions?"

Earlier, in the tavern, she was manipulated by Rōfu's emotions and ignited her anger.

But now, Tsunade was surprised to find that since Rōfu appeared, she inexplicably had an incomprehensible sense of goodwill and kindness towards Rōfu in her heart.

This feeling was not from the bottom of her heart, but rather… like… like every cell in her body was instinctively wanting to get close to Rōfu, so it made her waver.

Rōfu chuckled and shook his head, saying, "In fact, I didn't."

"Impossible." Tsunade said decisively, "If you didn't manipulate my emotions, then why would I… why would I have a inexplicable sense of goodwill towards you?"

"Why do you think it's something I did, instead of your instinct?" Rōfu said strangely.

"What do you mean by this??"

"The literal meaning." Rōfu explained, "The instinct of life is to pursue evolution, just like people who are beautiful, healthy, and have a rosy complexion can always give people a inexplicable sense of kindness at first glance, while aging, ugly people will always make people feel uncomfortable at first impression. This is the instinct of life. Just like the inexplicable goodwill you have towards me now, it's entirely because, in the essence of life, I have an attraction to you."

Stunned for a moment, after pondering Rōfu's words, Tsunade said uncertainly, "I am from the Senju clan, you are from the Uchiha clan, and the ancestors of the two clans came from the Sage of Six Paths. After the strength is improved, or the life is transformed, in order to seek stronger, under the instinct of blood, I will have a good impression of you, just like… just like my great-grandfather and Uchiha Madara."

Her eyes lit up, Tsunade increasingly felt that her guess was right.

You must know that the inexplicable feelings between Hashirama Senju and Madara Uchiha, even in the cognition of many Senju clan elders, are very unreasonable.

After all, the Senju clan and the Uchiha clan had been fighting for thousands of years, and even Hashirama Senju and Madara Uchiha's blood brothers had died at the hands of each other's clansmen.

But it just so happened that Hashirama Senju and Madara Uchiha, who should have been mortal enemies, became close friends that ordinary people couldn't understand. The two even cooperated to bring the entire ninja world from the chaotic Warring States period to the current era of ninja villages.

If this was because the two had developed their bloodlines to a certain extent, resulting in an attraction from their life instincts, then everything would seem reasonable.

My grandfather, because his Senju bloodline had been developed to the extreme, had an inexplicable affection for Madara Uchiha, who had also developed his Uchiha bloodline to the extreme.

It's just that Hashirama Senju and Madara Uchiha were both men, while I and Luo Fu are one man and one woman. This mutual attraction has produced an incredible change.

However, even if she understood this, Tsunade was still somewhat unable to accept it. She couldn't keep a straight face, and her pretty face flushed red as she said, "I don't care about any of that. In any case, you can't let me develop feelings for you."

Luo Fu glanced at Tsunade speechlessly and said, "I think the focus of your discussion with me should be everything I told you in the illusionary space before, right? And also..."

After a slight pause, Luo Fu said with a serious tone, "The essence of chakra!"

When this was mentioned, Tsunade couldn't care less about the feelings she had for Luo Fu that seemed to originate from the depths of her cells, even from the level of genes and bloodlines.

"You just said that I, who has developed the Yin Seal, should be able to perceive the essence of chakra. What does that mean?"

"Since the Sage of Six Paths appeared so many years ago, no one seems to have ever thought about where the chakra that was extracted but not fully utilized, instead dissipating inexplicably, actually went."

"You..." In an instant, Tsunade felt inexplicably terrified. She even vaguely felt a sense of understanding in her heart that what Luo Fu was about to say would truly subvert her worldview and even impact the foundation of the entire ninja world.

"It seems you've thought of it." Luo Fu smiled slightly, and his Mangekyo Sharingan opened again, instantly pulling Tsunade, who didn't resist, into the Tsukuyomi illusionary space once more.

Luo Fu didn't know the extent of the Sage of Six Paths' monitoring of the ninja world.

But one thing he was sure of was that his own chakra was independent of the entire ninja world.

When discussing these topics that couldn't be known by others with Tsunade, the best way to maintain secrecy was to enter the Kamui space or directly communicate in the Tsukuyomi illusionary space.

Apart from these two methods, any communication in the outside world was, in Luo Fu's opinion, unsafe.

Inside the illusionary space.

She felt a moment of nervousness when she was pulled in, but she quickly calmed down again.

Tsunade looked at Luo Fu and said, "You just said, in the thousand-year history, where did the chakra extracted by those ninjas go? When people die, their lights go out. Shouldn't that chakra dissipate into the world after their souls go to the Pure Land?"

Luo Fu sneered and said, "Dissipate? Then do you know that your granduncle, the Second Hokage Tobirama Senju, once created a ninjutsu that could interfere with life and death, the Impure World Reincarnation? This is a technique that can use sacrifices and the deceased's body tissues to summon the dead from the Pure Land to the human world, and they also possess infinite chakra. So, where does this chakra come from?"

"You even know about Impure World Reincarnation?" Tsunade was indeed a little surprised and said, "It seems that your Uchiha clan really started plotting something a long time ago!"

Luo Fu's mouth twitched, and he said with an unkind tone, "The Uchiha don't have that kind of brain."

Tsunade chuckled and said, "You're also an Uchiha, right? Are you saying that you don't have that kind of brain either?"

"You've already experienced my specialness. You don't still think I'm an ordinary Uchiha, do you?" Luo Fu looked at Tsunade with a wry smile and shook his head. "You also know the special nature of the Impure World Reincarnation technique. Then, have you or the former Second Hokage, Tobirama Senju, ever thought about where the infinite chakra of those dead summoned from the Pure Land comes from?"

Tsunade frowned and pondered for a moment before saying, "I've seen this question in my granduncle's notes, but my granduncle also guessed that the infinite chakra of Impure World Reincarnation should come from the Pure Land."

"Pure Land?" Luo Fu sneered and said, "I can tell you with certainty that before the mother of the Sage of Six Paths, there was no chakra in the ninja world."

"That's impossible!" Having witnessed Luo Fu's magic, Tsunade would not easily deny Luo Fu's words now. However, Luo Fu's statement that chakra was non-existent immediately was still somewhat unacceptable to her.

In shock, Tsunade quickly blurted out, "Since there was no chakra in the ninja world before the mother of the Sage of Six Paths, where did chakra come from? Could it really be because the Sage of Six Paths discovered the secrets of chakra?"

In the ninja world, after a thousand years, the myth about the Sage of Six Paths has long been distorted.

Even now, in the ninja world, when the Sage of Six Paths is mentioned, many people take it for granted and regard him as a purely fictional mythical figure.

In the myths, the Sage of Six Paths is a god who created the world, a creator god like the one who created the world.

Not being particularly clear about the truth, Tsunade could only guess the origin of chakra according to the description of the Sage of Six Paths in the myths.

Luo Fu quickly broke Tsunade's guess and said, "The chakra of the Sage of Six Paths comes from his mother, and his mother's chakra comes from outside the world."

Although the ninja world now has the concept of planets, in fact, for many people in the ninja world, they are more accustomed to calling the planet under their feet by the term "world" as if they were self-enclosed.

Now that Tsunade was on his ship, Luo Fu stopped being mysterious and began to talk about the ancient times, starting with Kaguya Otsutsuki and Isshiki Otsutsuki descending into the ninja world.

The God Tree, Kaguya Otsutsuki's betrayal, the creation of White Zetsu by Kaguya using the power of the God Tree in order to fight against the Otsutsuki main family, the birth of the Sage of Six Paths and his younger brother Hamura Otsutsuki, the brothers' rebellion against their mother...

Under Luo Fu's narration, the ancient past, which was like a myth, unveiled its mysterious veil in front of Tsunade.

"Hiss!!" Pinching her somewhat swollen forehead, Tsunade said, "Are you sure everything you said is true? My grandfather and Madara Uchiha are the reincarnations of the chakra of Asura and Indra, the sons of the Sage of Six Paths? The Rabbit Goddess left behind a third son before being sealed, and Madara Uchiha opened the Rinnegan and was fooled?"

After a while, finally accepting reality, Tsunade suddenly thought of Luo Fu's initial question.

She instantly felt a chill down her spine and said, "You... you wouldn't want to tell me that the Sage of Six Paths separated chakra out, and his intentions were... were malicious, right? Over the millennia, everyone who has extracted chakra has had their power harvested by the Sage of Six Paths?"

"I'm afraid that's the truth." Luo Fu said quietly, "Before Kaguya Otsutsuki, there was no chakra. Chakra was born after the God Tree devoured the natural energy of the ninja world. But the ninjas in the Pure Land have infinite chakra when they are reincarnated through Impure World Reincarnation. Where does the chakra of the Pure Land come from?"

"It's the collection of everyone's chakra over the millennia, so... so the reincarnated ninjas have infinite chakra." At this moment, Tsunade didn't understand that the so-called infinite chakra was a pseudo-proposition from the beginning.

For the people of the ninja world, the reincarnated ninjas of Impure World Reincarnation may indeed have infinite chakra, after all, that is the sum of all the chakra extracted by everyone over the millennia.

But this infinity is relative, not absolute. For a single ninja, Impure World Reincarnation does have infinite chakra, but for an entire world, the chakra of Impure World Reincarnation has a limit.

After Tsunade accepted this point, Luo Fu quickly said again, "Do you think that the Sage of Six Paths, who could clearly be immortal, why would he die? You should know that even Kaguya, who was sealed on the moon by him and his brother, has been able to live all along. The Sage of Six Paths used death as a pretext to hide in the Pure Land, harvesting the souls of ninjas. What is his purpose?"

"That's not right." Tsunade's eyes suddenly lit up and said, "Perhaps Kaguya Otsutsuki is immortal. But the Sage of Six Paths would die?"

Luo Fu watched Tsunade quietly, waiting for her to say the reason for this understanding.

"I remember you said that the Sage of Six Paths' younger brother, Hamura Otsutsuki, died on the moon after his lifespan ran out? Right? Since Hamura Otsutsuki died as a brother, then why do you think the Sage of Six Paths would not die?"
