Naruto: I'm really not an evil scientist!

Moreover, he didn't want to develop any weaknesses out of nowhere, because if someone targeted him, he could easily suffer a great loss or even die.

“Next, while Kars’ transformation ability is flexible, without Kars’ extensive knowledge and understanding of the characteristics of almost all animals, I’m afraid it would be…” Kakashi shook his head, feeling that this transformation ability was also a huge pitfall, and a trace of worry was revealed in his eyes.

“What you said makes some sense…” Hiruko pondered, tapping his fingers lightly on the table as he considered a solution. “But don’t worry too much. What I’m mimicking is Kars, the ultimate creature that is not afraid of sunlight. Even if the power is incomplete, it won’t give you the weakness of being afraid of sunlight.”

"As for the thirst for life energy, that certainly exists, but you can choose to drink Grell ore solution instead of killing, or you can hunt animals directly." Hiruko secretly admired Kakashi, the beta tester, for finding some suspected bugs so quickly. He could go back and experiment with White Zetsu to further improve the technology.

“However, you don’t need to memorize the genetic blueprints of all living things to transform. The cells in Kas's body contain genetic information that records the process of biological evolution. You only need to have a general understanding of the characteristics of some living things and be able to think of using your ability when needed.” Hiruko answered Kakashi’s questions one by one, his eyes full of confidence, as if everything was under his control.

In short, Kakashi doesn't have any other templates to choose from for the time being. He just wants to turn Kakashi into Kars, since they share the same voice actor.

In other words, he doesn't currently have virtual templates of Emiya Shirou and Ishida Uryu, otherwise he would also like to install them on Sasuke to play around and see what kind of amazing effects they would have.

In the movie, Kakashi couldn't escape Hiruko's clutches. When he was a young boy, the strange uncle Hiruko planted the Puppet Curse on him. Later, he was kidnapped with the curse mark on his head and used to perform the Yara Ritual. Then, he was swallowed whole by Hiruko.

In this world where the plot has been completely altered, Kakashi still cannot escape Hiruko's clutches.

Kakashi eventually wisely allowed Hiruko to have the Kars-like seal implanted in her body, and her body was also covered in some fancy tattoos that resembled curse marks.

However, it doesn't matter. During his service in the Anbu, Kakashi had already gotten quite a few tattoos on his body. He didn't dislike tattoos; on the contrary, he felt that they were a unique mark.

"My perception and calculation abilities seem to have improved a lot. I can completely quantify and calculate the temperature, humidity and even the specific composition of gases in the air."

Like the most sophisticated radar, even with my eyes closed, I can gain a powerful sensory ability that's almost like 'X-ray vision' and 'scanning' simply through the touch of my skin. Kakashi couldn't help but exclaim, his eyes filled with surprise, as if a door to a new world had been opened. This was a tremendous boost to his abilities.

The enhancement of his perception and brain's computing power is far more beneficial to a highly intelligent, technically skilled ninja like him than any fancy, deadly techniques. It's like giving a sharp sword a more precise aim.

"And this feeling..." Kakashi murmured, his body trembling. Then, with a "whoosh," a sharp blade formed from hardened bones and skin shot out from his right forearm.

These blades, extending from the forearms and legs, have countless sharp little hooks that can move the edge of the blade rapidly at the user's will, like a chainsaw. They can even reflect light and slice through high-speed spinning steel bullets.

"Corpse Bone Vein? No... it's Radiant Blade."

Kakashi quickly recognized the bone blade on his forearm. With a thought, his chakra surged and rapidly transformed into a large amount of lightning chakra.

Sizzle! Blue lightning crackled across the bone blade, which resembled a chainsaw, greatly enhancing its cutting power and imbuing it with enchantments that pierced and paralyzed it, making it seem like a blade from hell.

"Not bad, it seems that you and Kars are indeed very compatible, Kakashi, you have already unlocked Kars's Light Flow Technique so quickly."

Hiruko said with great satisfaction, a gratified smile on his face. It had only been a short time since the wedge was cast, and Kakashi had already evolved Kars's style, and it was very natural and smooth. This showed that Kars was really suitable for Kakashi. It seemed that he would soon be able to see the ultimate life form, Kakas.

"However, although your current physique has extremely strong self-healing and adaptability, it has not yet completely transformed into the level of the Pillar Men. It is best not to change your fighting style in the short term."

Hiruko instructed, his eyes filled with concern, "Try to go on fewer missions lately, and go to the hospital for regular check-ups. I'll have Shizune arrange it for you."

Although Kakashi was intelligent enough not to need Hiruko's reminder, Hiruko couldn't help but chime in. After all, Kakashi was the first beta tester to have a wedge inserted, so it was better to be cautious. Who knew if there would be any "win win win~" Kars aftereffects?

"Ah... I understand, Lord Hiruko." Kakashi paused for a moment, seemingly lost in thought and recalling something, before snapping back to his senses and replying.

Although Kakashi has a strong ability to manage his emotions, Hiruko still detected a faint scent of sadness emanating from him.

Kakashi is someone who habitually hides his sadness and worries in his heart, but for Hiruko, whose nose is now even more sensitive than Tanjiro's, all pretense is meaningless.

"It seems that you have quite a lot of talent, Kakashi." Hiruko carefully examined Kakashi and then said directly, "You just... saw the memories of the Sharingan, right? You even saw some of the memories of Indra, the source of the Uchiha bloodline."

Chapter 440

The technology he developed is by no means a simple superposition of functions, but rather a deep integration with the characteristics of the container itself. It is fused and evolved through precise calculations and countless experiments, and each breakthrough contains a profound understanding of the essence of life.

Human fetuses can complete the metamorphosis process that takes 900 million years to complete in just 10 months in the mother's womb. This series of amazing changes all originate from the memory codes hidden deep in the genetic factors.

The cells within Kars' body also contain genetic information that records the evolutionary process of life, allowing him to transform into any biological form at will, showcasing the infinite possibilities of the ultimate life form.

Clearly, although Kars has not yet fully evolved into the ultimate form, Kakashi has unexpectedly gained a special ability—extracting information from biological genetic factors. This ability is similar to the mysterious power of vampires in Underworld who obtain memories through blood.

Moreover, Hiruko seemed to detect a familiar Yin Release chakra fluctuation within Kakashi's mind.

“Indeed, I…” Kakashi was about to organize his thoughts to explain when Hiruko interrupted him directly: “You’re thinking about Obito again?” These words struck Kakashi like a bolt of lightning, leaving him completely stunned.

"..."

"—It's just the memories of the Sharingan at work." Kakashi was silent for a moment, then turned his head to the side, not denying it directly.

But what good would it do to Obito?

Because of Obito's past betrayal of Konoha, he will find it difficult to walk in the light again in this life. Even if you want to secretly see him or chat with him via video, Obito always seems to refuse to communicate.

It was only recently that he learned of Rin's resurrection from Lady Kushina, and that's why he came to him indirectly to inquire about it, but he didn't dare to go see Rin himself at all.

"You're not getting any younger, have you considered getting married?" Hiruko asked with a smile, a hint of mockery flashing in his eyes.

Unlike the gentle Tanjiro, Hiruko doesn't feel any empathy even when he can sense other people's sadness; he prefers to enjoy the pleasure he gets from Kakashi.

"what?"

Kakashi was startled and cautiously replied, "Lord Hiruko, I feel I'm still very young, and I don't yet..."

Lord Beiluhu is always so imaginative, his thoughts leaping so unexpectedly that they catch people off guard.

"Do you want to be a virgin for the rest of your life?"

Hiruko threatened, "Once you become an ultimate life form like Kars, you will lose your sexual ability and will no longer be able to reproduce. So you must resolve your life's most important matter as soon as possible within the next year or two, otherwise the Hatake family line will end."

This is of course a lie. The fact that ultimate beings do not need sexual intercourse does not mean that they cannot have sex. As for being unable to reproduce, that is even more absurd. Moreover, even if they really could not reproduce, Hiruko has the power of blessing to make up for it.

"What?! Lord Hiruko, are you telling the truth?" Kakashi exclaimed in shock.

As a loyal fan of Jiraiya, besides reading some literary and violent novels, he also dabbled in Jiraiya's erotic novels, naturally making him a repressed "theoretical master".

Although he wasn't as unrestrained as Jiraiya, and was simply rich in theoretical knowledge, he still had fantasies about that aspect deep down.

"Are you really not even a little bit attracted to Lin?"

"I……"

"Don't say anything, we're all men, I understand."

"Lord Beiliuhu!"

"Moreover, I heard that you've also provoked Hua Bing of the Snow Clan, and another woman named Hua Ling. You're quite the ladies' man, aren't you? How about marrying them all and setting an example for the men of Konoha?"

"Huh?" Kakashi's refusal was within Hiruko's expectations, but he didn't really need Kakashi's agreement.

Whether it succeeds or not is not within Hiruko's considerations, or rather, whether it succeeds or not, Hiruko has achieved his goal.

It would be enough if he had suggested that Kakashi marry three female ninjas, including Rin Nohara.

After that, the female ninjas who admire Kakashi will be unable to sit still and go to Kakashi to confirm, or they will become suspicious. Then, whether it's a romantic comedy or some kind of stomach-ache drama, Hiruko is happy to see it happen. Anyway, he loves to watch the show.

Then, Obito Uchiha would be driven mad with jealousy, becoming an even more insane lemon spirit than Danzo Shimura.

After all, Hiruzen Sarutobi merely "stole" the Hokage position, while his best friend Kakashi Hatake was about to become the Hokage he had always dreamed of and marry a girl who was more important than his own life.

In his own imagination, Kakashi will take over all the career and love that "should have belonged to him." This feeling is even more bittersweet than being taken advantage of by your best friend.

Whether or not this event will happen, as long as Obito firmly believes that the future might develop in this direction, he will definitely go crazy.

This matter didn't bring any real benefit to Hiruko. People are complex. Just like the Joker, who just wanted to see the world burn, Hiruko was just acting on a whim. As the popular internet meme says, he simply wanted to see Obito's pained, twisted, and jealous expression, and Kakashi's stomachache and helplessness. He was just a research villain who built his happiness on the suffering of others.

After all, as a research ninja, Hiruko's forte was studying the mysteries of human nature and chakra. For him, this kind of psychological experiment was just an interesting game.

……

On a desolate open space, a girl with white eyes who looked somewhat childish but whose figure was already quite developed suddenly appeared.

"Is this the trial instance arranged by Master?" Hinata Hyuga immediately activated her Byakugan after landing, carefully observing the situation within a radius of thirty kilometers.

As a girl addicted to the internet, she has played a lot of battle royale games, and she doesn't want to be eliminated as soon as she lands.

Although these spaces were created by Lord Hiruko and have special rules, where death here would result in elimination rather than actual death, but rather being teleported back to the Ninja Academy, Hinata didn't want to be kicked out of this game instance so early.

Itachi Uchiha briefly explained that in this joint exercise, everyone would be randomly placed into an unfamiliar environment filled with various dangers, and then everyone would have to survive in this world for at least three days.

You can seek teammates for cooperation, or you can become a lone strongman; as long as you can survive for three days, you've passed the test.

"Looks like I know quite a few people around here," Hinata muttered. A quick glance revealed that she knew at least five or six people within a 30-kilometer radius.

Hinata began to consider whether she should quickly gather companions to act as a team, or simply go it alone and recklessly conquer this dungeon.

"We'll be staying for three days. Food is a big problem." The girl scratched her head in distress. Although the ninja academy had given everyone a miniature scroll containing food, the food was only enough for an ordinary person, not for her, a big eater.

Hinata made a decision: she would not be a lone wolf; she would gather teammates and collect food from them. In return, she would protect these teammates who had paid "protection money."

"What bad luck! What bad luck!" Nara Shikamaru shouted as he jumped around, and this time he landed directly on the head of a demon and almost "died instantly." He was really unlucky.

Several dark shadows slithered behind Shikamaru, occasionally reaching out as if to grab him, but Shikamaru was as slippery as an eel and was never actually touched.

"That's... Shikamaru?" Hinata Hyuga asked, somewhat surprised.

As far as she knew, Shikamaru was somewhat weak in strength, but he was quite intelligent. Combined with his family's secret techniques and some scientifically advanced ninja tools with unique functions—all developed by Hiruko-sensei—he was quite troublesome overall. Surely he shouldn't be in such a sorry state?

"Ah, it's Hinata!" Shikamaru's eyes lit up, and he immediately ran towards Hinata. He knew Hinata's fighting strength well. If he could cling to Hinata's coattails, he might be able to get through this trial.

"Shikamaru, hand over half of the food you have, and in exchange, I can protect you for a while," Hinata said as she saw Shikamaru running towards her.

In her opinion, Shikamaru was a cunning and wicked boy who ran towards her without saying a word, perhaps with the intention of diverting trouble. Therefore, she could ask for food without any guilt.

“Okay!” Shikamaru readily agreed, and reminded him, “Be careful, the enemy is not an ordinary human. They have extremely strong self-healing abilities. Even if they are blown up by explosive tags, they can recover. They are very difficult to kill in a normal way.”

It was precisely because his opponent could quickly recover regardless of whether he used his shadow to strangle them or his explosive tags to detonate them, and because his opponent seemed to be able to swim in another dimension and launch fearless attacks from three different directions at any time, that Shikamaru made the decisive decision to run away.

He didn't want to fight a war of attrition against an immortal enemy in an extremely unfamiliar and dangerous area. If he ran out of ammunition and supplies or was careless for even a moment, he would be finished.

Moreover, this trial grounds will definitely not contain only one monster; dangers will surely be everywhere. Hinata not only possesses the Byakugan with its extremely strong reconnaissance abilities, but she is also extremely powerful, making her undoubtedly the most suitable support for this trial besides Naruto.

It's only a matter of giving up some food; getting Hinata along with you is definitely worth it.

"Immortal?" Hinata revealed a mischievous smile. "That must be incredibly durable."

"Kid, why aren't you running anymore?"

A horned demon emerged from the black "mud" and exclaimed with delight upon seeing Hinata, "Ah, a fresh young girl! Finally... I can have another delicious meal!" The demon excitedly ground its teeth, seemingly recalling the taste of devouring young girls in the past.

Within this space, the demons' memories of falling into hell are temporarily blocked; they only know how to kill all non-demon creatures, and all the demons retain the same brutal nature as in their previous lives.

"Tsk! What a disgusting creature." Hinata frowned upon hearing the grinding teeth, feeling a surge of annoyance. With a stomp of her foot, she instantly appeared before the demon.

Boom—! Hinata's right fist, burning with the flames of a lion, smashed the demon's head, giving the demon no chance to hide in the "swamp" on the ground.

"The hardness is just average."

Hinata observed the monster before her, somewhat speechless. "While its self-healing speed isn't slow, it's not exactly fast either. Shikamaru, you can't even handle something like this?"

"Be careful, he has two more clones!" Shikamaru warned as he saw two dark figures suddenly appear on the ground.

Four hands reached out from the shadows, seemingly trying to grab Hinata's legs and pull her into the "swamp" that was almost like another dimension.
