Naruto: I'm really not an evil scientist!

Hiruko shook his head; he truly couldn't fathom what girls were thinking.

However, in his opinion, it was a waste of time to teach medical ninjutsu to those undisciplined, lively, and active children.

Having the maternal and gentle Pharmacist Nono as the teacher is undoubtedly the best choice.

Moreover, this way, Pharmacist Nonou can have an extra source of income, allowing the children in the orphanage to live a more stable and comfortable life.

They even have the ability to sponsor some children to audit classes at the school. Wouldn't that be a win-win situation?

"Tch, Hiruko! What you're saying really makes me uncomfortable." Tsunade pouted in displeasure, her face full of displeasure.

Seeing this, Hiruko quickly approached with a grin, gently placing his hand on Tsunade's shoulder in an attempt to ease the tension.

Suddenly, the atmosphere between the two became subtle and ambiguous.

"asshole!!"

After a round of laughter and playful banter, the atmosphere inside the room became even more lively.

Hiruko lay lazily in Tsunade's arms, a teasing smile playing on his lips, and asked, "How well have you mastered the medical ninjutsu I just taught you?"

"And what about the Wood Release technique? Has there been any new progress?"

"Sigh, I've barely learned some of Grandpa's techniques, but his Wood Release ninjutsu is just too weak for me," Tsunade muttered helplessly.

He then continued, "As for advanced Wood Release ninjutsu, I've only learned the Wood Dragon Technique so far; I haven't even scratched the surface of the others."

Although Hiruko was there to help and guide her, the power of Tsunade's Wood Release was worlds apart from that of her grandfather.

In Tsunade's view, she had not fully mastered this ninjutsu.

"However, combining my knowledge of medical ninjutsu, creating some highly poisonous vines, or making flower buds emit pollen with superimposed effects of anesthesia, paralysis, and corrosion, is still quite easy for me to do."

Tsunade can even combine medical ninjutsu with these special pollens to make them a life-saving medicine.

Like a slug, it transforms into a medium for restoring chakra and healing the bodies of allies.

Compared to Hashirama Senju's powerful and expansive Wood Release ninjutsu.

Although Tsunade could not fully inherit her grandfather's Kamui, she still displayed the style of the Legendary Sannin.

She did not blindly pursue her grandfather's power.

Instead, it should be applied flexibly according to one's own physical condition and actual situation.

The combination of medical ninjutsu and wood release ninjutsu can produce unexpected and unique effects.

Wood Release ninjutsu mostly replenishes itself by absorbing the life force of the earth or living beings, directly nourishing the vines with life force, and can also infuse nutrients into patients.

This effectively compensates for the drawback of Tsunade's use of healing ninjutsu, which would accelerate cell division and increase the burden on her body.

She can even continuously replenish her life force through Wood Release, keeping herself in peak condition at all times.

They can always be ready to engage in battle or rescue with full energy and abundant chakra.

Hirukoya taught Tsunade the power of Sage Mode, but it was merely a modified version of his own.

The slug's Sage Art is too terrifying; Tsunade is not capable of undergoing that kind of trial right now.

This is also one of the abilities that Hiruko taught to Nohara Rin.

Hiruko transferred Sage Chakra to Tsunade. Although Tsunade was a little awkward at first, she eventually completely relaxed her body.

He allowed the black stripes carrying natural energy to invade his body.

Hiruko placed a mark on Tsunade's chest as the starting point for guiding her Sage Mode.

Tsunade has always been generous in passing on her family's secret techniques, and even all her special techniques, to Hiruko.

As for Beiliuhu, he naturally wouldn't hold back anything he had developed.

Throughout the entire ninja world, there are three universally recognized sacred sites where one can resonate with natural energy to cultivate Sage Mode.

These three sacred sites are actually similar to gathering places for monsters. They are like spiritual lands that absorb the essence of heaven and earth, allowing the creatures within them to have long lives.

While broadly speaking, the immortal arts of the three holy lands are essentially the application of natural energy.

However, based on their respective races' talents and the natural attributes of the blessed lands they occupied, they developed different schools of immortal arts, each with its own unique characteristics.

These creatures, like monsters, absorb the spiritual energy of heaven and earth, seize the creation of heaven and earth, and ultimately become immortals.

However, the immortal forms and abilities they achieve are all different.

Just as humans have developed various cultivation methods based on physical constitution, cultivation period, racial differences, etc., such as cultivation methods classified into five categories: metal, wood, water, fire, and earth.

Some creatures prefer to absorb the spiritual energy of the morning dew, while others prefer to cultivate under the glow of the sunset at night, and still others directly absorb the intense energy of the sun when it is blazing.

Even a basic breathing technique in the world of martial arts, after being interpreted by different people and refined over the years, can give rise to countless unique and mysterious martial arts manuals, all of which are crystallizations of wisdom.

Simply feel and absorb natural energy to enter the immortal mode.

It is the safest cultivation method that Biluhu can currently master.

But Hiruko was clearly not satisfied with this; what he wanted was the techniques of the three holy sites regarding the use of natural energy.

He wanted to learn more about the deeper mysteries of natural energy, including how to extend lifespan using these natural energies.

In this way, he can avoid many detours and lay the foundation for creating a cultivation method of immortal arts that is very suitable for him.

He could even analyze the divine tree's ability to absorb natural energy and transform it into his own cultivation abilities.

By imitating this principle and applying it to the human body, one can improve their efficiency in absorbing natural energy.

He wanted to understand how the three treasures of essence, qi, and spirit condensed into the image of the three flowers gathering at the top of the head, or simply use the divine tree as the foundation of cultivation and embark on a scientific path of spiritual cultivation.

As a transmigrator from China, Beiluhu has always harbored a mysterious longing for the idea of ​​cultivating immortality.

In his view, everything can cultivate immortality, and cyber beings who cultivate immortality are also immortals!

Ultimately, even though Tsunade was unwilling, she had no choice but to go to Shikkotsu Forest to practice Sage Mode after learning about these circumstances.

After all, with the sage magic seal given to her by Hiruko, it was only a matter of time before she could achieve sage mode.

Of course, Hiruko did this so that Tsunade would have more time to come and stay with him.

After all, the two are now close, and they need to understand each other's training progress and situation. In Hiruko's heart, Tsunade is someone he cherishes.

After a period of pleasure, early the next morning...

After rinsing herself again, Tsunade hurriedly left.

Hiruko rubbed his lower back, stretched slightly, then tidied himself up and headed to the research department to continue his research.

That night, after finishing his physical training, Hiruko walked out of the bathroom and felt that his body had recovered to its best condition.

Time passed slowly.

Tsunade also went to practice Sage Mode.

Raindrops slid down one by one, dripping onto the long-parched earth. It was truly a timely and welcome rain.

The daimyo of the Land of Fire sat leisurely in the tea room, holding a cup of hot tea, quietly gazing at the gift of nature outside the window.

He seemed very relaxed and at ease.

The older he got, the more he liked rain, because rain is pure rain, without any other complicated elements mixed in.

"If only everyone could be as pure as rainwater," the Daimyo sighed, then moved the chessboard to his side and began playing chess alone against the Finance Minister opposite him.

Undoubtedly, this is something that seems to have little significance.

Although the finance minister was a skilled chess player, he dared not beat the daimyo when playing against him.

Therefore, when the two played chess, the daimyo always felt that he was missing some of the fun of meeting a worthy opponent.

However, the daimyo still enjoyed it immensely, because when playing chess with the finance minister, he didn't need to rack his brains to guess what the other party was thinking.

There's no need to constantly monitor the other party's intentions, since the finance minister is his closest and most trusted confidant.

Others might not be able to understand this feeling, but for the daimyo of the Land of Fire, loyalty was the problem that plagued him throughout his life.

How many people would act recklessly in his name, and how many would remain silent yet dedicate their lives to fulfilling their mission of loyalty?

He couldn't tell, he really couldn't see it clearly.

As the ruler of a nation in the industrial age, Daimyo deeply felt the difficulty of governing the country.

He couldn't see how many people were truly loyal to him.

In terms of the actual area under his rule, he may not be as great as his ancestors, but his ancestors only needed to do one thing well—keep the peasants on the brink of starvation—to maintain their rule.

However, everything changed after the advent of industrial society.

The farmers, who had previously only focused on the soil beneath their feet, began to look up and gaze around, yearning for more.

Those hereditary retainers professed loyalty, yet they engaged in activities that constantly damaged the daimyo's prestige.

The daimyo wanted to stop it, but he didn't have many options, because his power was extended through the support of these retainers.

Without the support of these retainers, his influence probably wouldn't even have spread beyond his own city.

He was bewildered by the changing times and felt a profound sense of powerlessness.

He found himself unable to keep up with the pace of young people and the changes of the times.

The sudden realization that he was getting old was truly painful for him.

Originally, we could eat two chickens in one meal, but now we can only eat a little bit of chicken leg meat.

However, the accumulation of time and experience is not entirely useless.

At the very least, some of his attendants were quite considerate.

Soon, the attendant beside him handed the daimyo the information about the villagers that he had prepared.

One family was mentioned whose business had been mediocre for some unfortunate reasons.

This family never really cared about the salt business because some of their subordinates were so greedy that they lied about the profits from the salt industry, making the family believe that the salt business only made a small amount of money each year.

Therefore, when Konoha made the acquisition offer, they readily agreed and received a large sum of valuable cash flow in return.

But who could have imagined that these originally ordinary salt companies would miraculously turn a profit and make a fortune once they came into the hands of Konoha?

Speaking of the current state of that family, the patriarch's anger goes without saying.

They were furious that their subordinates had lied to their superiors and misrepresented profits, and even more upset that Konoha had taken the profits that should have been theirs.

In their view, seeing others make money is more painful than losing money themselves.
