Naruto: I'm really not an evil scientist!

He used to think it was absurd that Ash could always snag starter Pokémon or even pseudo-legendary ones, and that some idiots would willingly give up such rare Pokémon. Now he seems to understand it a little better; some idiots really do have bizarre thought processes.

After a long while, Kanroji Mitsuri, who had been sunk, collapsed weakly. This girl, who was capable of tearing apart the Demon King in the future, finally revealed her vulnerable side.

Just then, cherry blossoms suddenly began to fall from the sky.

"Huh?" Kanroji Mitsuri tilted her head, her mouth slightly open.

She wondered if she was hallucinating because of the shock. She saw the cherry blossom tree in front of her turn into a handsome silver-haired man surrounded by fragrant pink cherry blossom petals.

Watching the cherry blossom tree transform into a handsome man, waving his hand to don a loose, light garment made of petals, and then this handsome man walking towards her step by step, this dreamlike scene made Kanroji Mitsuri's heart beat faster and faster, her cheeks flushed red, and her breathing gradually became rapid.

“You’ll catch a cold sleeping on the floor.” Hiruko bent down, revealing a gentle smile, and offered her right hand.

Cherry blossoms fluttered in the air, and the refreshing sunlight fell just in time on the man's profile, perfectly highlighting his handsome features and heartwarming smile. Everything was as gentle and beautiful as a dream.

"Th...thank you!" Kanroji Mitsuri blushed to the roots of her ears, grabbed Hiruko's warm right hand, and then stood up abruptly. However, after standing up, she was reluctant to let go of that warm hand.

"Um, Miss Kanroji, are you upset because your blind date failed?"

Hiruko smiled slightly, gently placing his hand on Kanroji Mitsuri's shoulder without withdrawing it, his gaze carrying a hint of gentleness and inquiry.

“Yes…” Kanroji Mitsuri stammered, her head slightly lowered, a blush rising on her cheeks.

"You don't need to be bothered by the words of a mediocre person,"

Hiruko's voice was deep and magnetic, "Being exceptionally gifted and physically strong is not a flaw; on the contrary, it's a source of pride. It shows that you are blessed by the heavens. Those who speak ill of you are merely envious. Besides, I really like your hair color~"

As he spoke, he leaned close to the girl's ear and gently breathed into her beautiful, dreamlike hair, which swayed softly in the breeze like dewdrops in the morning light, shimmering with a captivating luster.

The girl, who was always treated as an oddball and criticized in the past, could not withstand such praise and teasing. Her body went weak and hot, and she fell into Hiruko's arms. She had never felt such a heart-fluttering feeling before, as if the whole world had stopped.

"If this is a dream, please don't let me wake up..." Mitsuri Kanroji murmured, her voice trembling with longing. She subconsciously reached out and touched Hiruko's chest, feeling its firm and warm touch.

After a while, Kanroji Mitsuri finally realized that she was not dreaming. The place where the cherry blossom tree used to grow was empty, and she was surrounded by a refreshing fragrance, as well as a gentle and handsome man who was close to her and was not a figment of her imagination.

"Thank you, Lord Yokai!" Kanroji Mitsuri was very excited, her eyes glistening with tears.

Chapter 400 Mitsuri is so cute

For some reason, even though she sensed that the person beside her might not be human but a monster, she felt no fear. Instead, she was filled with joy and even felt an indescribable excitement, as if she had found her home in life.

Taking advantage of the situation, Hiruko easily captured Kanroji Mitsuri—a silly girl who longed to be truly accepted, was innocent and cute, and possessed tremendous strength.

With his profound expertise in the field of physical research, he won the approval of his parents in just a few days.

After all, all it takes is a little tenderness to win over a cute, sexy girl with eight times the muscle density of an average person. Why not?

He considered himself an old man of kindness, and had seen many instances of Orochimaru abducting children. Abducting someone in the same manner was nothing new to him.

……

Moreover, Kanroji Mitsuri is indeed very easy to win over.

Hiruko knew very well that as long as she didn't dislike the girl, genuinely accepted her and expressed her affection, and then fed this big eater girl with delicious food, her favorability would skyrocket.

She's so much easier to raise than modern-day fairies.

Using his research skills, he created a customized nutritional meal plan for Kanroji Mitsuri, satisfying her appetite while ensuring her health.

Moreover, Kanroji Mitsuri's parents did not make things difficult for Hiruko. On the contrary, they were glad that their daughter, who had been different since childhood, had finally found someone who could truly accept her and was able to get married.

……

After all, when Mitsuri was only 1 year and 2 months old, she was able to easily lift a 15-kilogram pickling stone to help her pregnant mother, which was truly astonishing.

Because she ate 170 sakura mochi for eight consecutive months, her originally black hair turned into a gradient of sakura pink and grass green. Although this was equally outrageous, it was still considered normal compared to Zenitsu Agatsuma's hair coloring after being struck by lightning. However, in the eyes of ordinary people, she was still an absolute oddball.

Mitsuri Kanroji's physique far surpasses that of ordinary people, with muscle density eight times that of a normal human. Despite being a woman, she possesses unimaginable strength and is destined to tear apart the Demon King Muzan with her bare hands.

Her appetite was also enormous, almost exceeding the combined appetite of three sumo wrestlers.

These unusual behaviors often drew criticism from Kanroji Mitsuri in a society filled with ignorance and prejudice.

She was not popular in mainstream Japanese society at that time.

The appearance of Hiruko was like a ray of light, illuminating her dark world.

After sending out White Zetsu to gather intelligence and confirming through repeated investigations that this was indeed the world of Demon Slayer, Hiruko's mindset immediately calmed down, and she regarded this world as a safe place to relax.

So, after getting married, he opened an ordinary general store in a remote corner of the town and lived a simple and happy life with Kanroji Mitsuri, almost like a hermit.

He used his research skills to continuously improve the products in the grocery store. Although the business was not booming, it was enough to make a living.

More importantly, he had more time to spend with Kanroji Mitsuri and enjoy this hard-won happiness.

Yoriichi Tsugikuni, who single-handedly raised the ceiling of the world's military strength, has long since passed away.

Hiruko felt a pang of regret at not being able to meet this being who could be considered a divine being.

In his eyes, Muzan Kibutsuji, the demon king who had lived for a thousand years but was still mediocre, was nothing but trash, far inferior to the learned and talented Emperor Shitian in "Storm Riders".

Although the old emperor could only unleash the Emperor's Heavenly Thunder after his breakthrough, the knowledge in his mind was a huge treasure, while Muzan, apart from a pile of rotten flesh that would die in the light, had a brain like a lump of mush.

Hiruko despised Muzan Kibutsuji not only because he thought Muzan was weak, but also because he saw Muzan as utterly incompetent and whose abilities overlapped with those of the Pillar Men. Therefore, Hiruko had no interest in recruiting him.

Hiruko wouldn't actively search for Muzan, but if she happened to run into him, she wouldn't let go of this scum who could be used as an experiment.

With his abilities in physical research, he was fully confident that he could thoroughly study Muzan, that scumbag demon, and might even discover new research inspiration from him.

Muzan proclaims himself a calamity of nature, so Hiruko will become Muzan's calamity of nature, leaving him nowhere to hide.

However, Hiruko was generally quite satisfied with this world because it was relatively safe.

For Hiruko, there is no need to worry about terrifying enemies in this world, nor is there the sudden appearance of a strange Stand that could cause the universe to be destroyed instantly, or the invasion of a parallel world, as is the case in other worlds.

Within a century, he will not need to worry about alien invasions of the world.

Hiruko didn't need to rush to plunder this world; simply being able to stay in this world was enough to secure his future.

He can peacefully conduct his physical research here and enjoy this tranquility and happiness.

The grocery store was doing a bit of a slow business, after all, Hiruko didn't really make a living from the store.

Inside the courtyard, however, it was bustling with activity, as if an open-air banquet was being held.

White Zetsu kept emerging from the ground, bringing fresh ingredients, which were then processed into various delicious dishes and served on a large table next to the cherry blossom tree in the yard.

White Zetsu have a wide range of evolutionary branches. Especially after Hiruko obtained the technology of Gaia Memory, it was only a matter of a moment for him to create a few White Zetsu who were skilled in cooking to satisfy his appetite.

Moreover, Hiruko copied Earth's database and possessed a vast collection of recipes.

In the days since their marriage, he has been able to get White Zetsu to cook different dishes every day, allowing Kanroji Mitsuri to enjoy a feast.

"Mmm...it smells so good, Mother!" Kanroji Mitsuri walked over, her eyes sparkling with excitement as she looked at the delicious and generously portioned dishes on the table.

She picked up a piece of meat with her chopsticks, took a bite, and felt incredibly happy. The joy of a foodie is that simple.

"Eat up, but while you're enjoying your food, don't forget the little trick I taught you," Hiruko said as he served Mitsuri some food.

He did not intend for Kanroji Mitsuri to join the Demon Slayer Corps to learn Breathing Techniques, but he was very clear about the importance of power.

So he gave Mitsuri some chakra, another achievement of his physical research, which could enhance the strength and endurance of the human body.

At the same time, he also taught Mitsuri how to practice Ripple Qigong, as well as some tips on how to quickly digest food and convert it into chakra for storage, or decompose it into life energy to promote the body's evolution.

These digestive tips were the result of Hiruko's research on Samehada, and were his exploration of immortality. They are a kind of pirated version of the Six Treasures of Immortal Thieves, and are very suitable for a foodie like Mitsuri.

He was well aware that Kanroji Mitsuri had a special constitution and an amazing appetite, which could easily put a strain on her body if not controlled.

These tips help her digest food better, converting nutrients into energy needed by her body and promoting physical evolution.

The breathing techniques of this world are indeed quite unique. When cultivated to the extreme, under certain conditions, they can unlock abilities such as markings and the ability to see through the world.

The ability to display markings and the ability to see the transparent world are actually innate abilities of Yoriichi Tsugikuni, the founder of Breathing Techniques.

The ability to see through the world is good; it's a kind of perception similar to the unity of man and nature, and it also has a certain ability to accelerate and conceal one's breath. It can enhance control over one's own muscles, allow one to see through the human body, perceive and predict the enemy's attack, and if used for learning, it can quickly master a large number of skills.

In terms of combat, to put it bluntly, it's equivalent to a martial arts version of Byakugan combined with Observation Haki.

Swordsmen who practice breathing techniques need to reach a body temperature of 39 degrees Celsius and a heart rate of over 200 beats per minute to unlock their markings, which puts a great strain on the body.

Once the markings are activated, they can greatly improve physical fitness, essentially acting as a powerful buff.

Moreover, once one person activates their mark, it will resonate with others, making it easier for them to activate their marks as well.

However, apart from Yoriichi Tsugikuni, who was born with the mark and was able to die of old age, swordsmen who awakened their marks through breathing techniques either accelerated the passage of their lives or squeezed out their own life force, and basically did not live past the age of twenty-five.

If someone over 25 years old activates their markings, they may even die on the spot after the battle.

Compared to the Ripple Breathing Method, a health-preserving qigong that can prolong life, the breathing methods in this world are more aggressive, focusing on strengthening bodily functions but offering no benefit for longevity. In fact, except for those with exceptional constitutions, the stronger one cultivates the breathing method, the faster one dies.

Therefore, Hiruko might study breathing techniques and combine them with the Seven-Day Breathing Method to try to develop a superior breathing technique.

This is another challenge for him in physical research, and also his pursuit and exploration of immortality.

However, he would not allow Mitsuri to practice breathing techniques to unlock her markings, such a life-threatening thing, until Hiruko had thoroughly researched it.

Improving physical fitness is just one of many harmless and effective methods for Hiruko; he doesn't need another one.

He was well aware that Kanroji Mitsuri had a special constitution and needed to be cared for with extra caution and meticulousness.

"I won't forget it. I remember every word the demon lord said to me~" Kanroji Mitsuri said sweetly.

Although she already knew that Hiruko was not a cherry blossom spirit, the dreamlike scene of meeting Hiruko that day was still firmly etched in her mind.

She knew very well that whether Hiruko was teaching her Ripple Qigong or how to eat, it was all for her own good.

The feeling of being cared for by someone she likes is wonderful, making her feel incredibly happy and fulfilled.

Kagaya Ubuyashiki knelt on the tatami mat, coughing repeatedly. After hearing the urgent information, he felt it was somewhat outrageous: "Cough, cough... Is this information accurate?"

"Although it is unbelievable, my lord, recently some people have indeed witnessed a large number of pale, humanoid monsters that can burrow underground appearing in the sunlight," Yin said, kneeling on one knee with a worried expression.

In his view, anything that could burrow underground and was deathly pale and inhuman must be a ghost, and only a ghost could possess the Blood Demon Art, an ability that was almost a supernatural power.

Calling them monsters is probably because ordinary people don't know about the existence of ghosts, so when they see strange or supernatural scenes, they simply call the other party a monster.

After all, although demons have always been rampaging and devouring people in this world, due to the cowardly Muzan's deliberate control and certain special reasons, demons have become a non-existent urban legend in the eyes of ordinary people, no different from monsters.

The fact that these ghosts can appear in sunlight may be related to the other party's blood demon magic, or perhaps the ghosts have finally evolved the ability to survive in sunlight. Either way, it's not good news.

"Large quantities? Eyewitness accounts?"

Kagaya Ubuyashiki repeated those two words, then suddenly asked, "Have there been any missing persons or heinous murders reported in the area where the witness was located?"

“This…” Yin was taken aback for a moment, then seemed to realize something, “Not at all.”
