Naruto: I'm really not an evil scientist!

Uchiha Tetsuka vaguely sensed that his strength had made a slight breakthrough.

Orochimaru, standing to the side, saw how effective Hiruko's potion was and his eyes immediately lit up with excitement. He was eager to try it and was filled with intense curiosity about it.

He then immediately ordered the ninja beside him to use animal needles to draw several tubes of blood from the Uchiha ninja in front of him.

They immediately went to the side to have the samples tested.

"Hiruko, you really are a genius!" Orochimaru exclaimed.

"I never imagined you could create such a restorative substance that can rapidly divide human cells, quickly restore physical strength and chakra, and even heal injuries."

During the drug's active period, its effects are almost comparable to Tsunade's forbidden technique, Creation Regeneration.

Orochimaru then shook his head and muttered to himself, "No, this shouldn't just achieve the effects of medical ninjutsu."

Although the extraction of this substance is not easy and has significant side effects, it has great potential for recovery.

On the battlefield, this ability can be a key factor in determining victory or defeat at crucial moments.

Just like the Akimichi clan's three-colored pills.

Despite the potentially life-threatening aftereffects, the Akimichi family has always regarded it as a lifeline in critical moments.

"And the Uchiha's physique seems to be able to resist the side effects of these drugs..." Orochimaru narrowed his eyes slightly, pondering to himself.

"Is it the Sharingan's ocular power at work?" On his path to immortality, he became increasingly interested in studying these mysterious bloodstains.

Time passed quietly, and Hiruko came out with three portions of pills. Each portion contained seven or eight different sized particles, each with a different color, creating a colorful display.

He solemnly placed the pill in front of the three men, reminding them that this drug experiment was quite dangerous.

"I cannot fathom what kind of spiritual world you will construct that fully simulates the five senses."

But I can assure you, it will be an extremely tragic and sorrowful world.” Hiruko’s tone was full of seriousness.

"There, you will hardly realize that it is an illusory world, and I do not know what you will experience."

But it's crucial to maintain mental stability; once you have a mental breakdown, there's no going back.

After saying that, Uchiha Tetsuka stepped forward, took seven or eight pills from Hiruko's hands, and swallowed them all in one gulp.

Finally, he swallowed the fist-sized silver flower whole.

In an instant, an extremely cold chakra emanated from Uchiha Tekka's body. The chakra that made people feel dark, oppressive, heavy, and uneasy was instantly detected by everyone present.

The pill's effects began to take hold, continuously suppressing the chilling chakra aura.

The next second, two lines of blood slowly flowed from Uchiha Tekka's tightly closed eyes, leaving two bloody marks on his face.

Although only three seconds had passed in reality, in his mental world, more than a decade had actually passed.

As Fugaku Uchiha carefully examined the flow of chakra within Tetsuka Uchiha's body with a serious expression, Tetsuka's tightly closed eyes suddenly snapped open.

A burst of Kage-level chakra, accompanied by a frenzy in his eyes, suddenly erupted, immediately alerting everyone to the impending danger.

Having already made preparations, Hiruko acted swiftly. He sat cross-legged on the ground, formed hand seals, and instantly countless sealing chains wrapped around Uchiha Tekka's body.

However, in the next second, Uchiha Tekka's body lost control due to the dark shadow on the ground, and he seemed to still be immersed in the illusion.

He instantly unleashed an extremely powerful burst of chakra, breaking free from the sealing chains.

Immediately afterwards, he unleashed a dazzling Fire Release: Great Fireball Technique, with scorching flames spewing from his mouth and condensing into an exceptionally large fireball in the air.

Instantly, the snakes that Orochimaru had just summoned were roasted and sizzled.

At the same time, Fugaku and two other Uchiha clan members acted in unison, quickly subduing Uchiha Tetsuka and knocking him unconscious.

Fugaku Uchiha looked at Tekka lying on the ground and pondered to himself.

Uchiha Tekka's mind may have been severely traumatized, and he was temporarily unable to distinguish between illusion and reality.

Hiruko quickly stepped forward and carefully examined Uchiha Tetsuka's physical condition using medical ninjutsu.

After confirming that he was alright, they openly drew another large tube of blood.

Hiruko instructed that once Uchiha Tetsuka woke up, he should remember to come over for a check-up.

As he spoke, he smoothly sifted the blood sample in his hand into a specially made container, and then handed the other two pills to Fugaku.

"Is this considered a success?" Fugaku asked curiously.

"In my opinion, it was a success, but the next step depends on his mental state. I suggest that the other two members of the tribe take it again after a period of time."

Hiruko waved his hand, indicating that everyone could leave.

Fugaku glanced at the messy laboratory and decided to leave with his clansmen first.

However, Uchiha Shisui did not leave with them; he stayed behind to help restore order to the laboratory.

As night deepened, Hiruko, pleased with the success of today's experiment, planned to visit Yekura's room that night.

The room was very clean, thanks to the adorable Rin Nohara.

Pakura's breathing was erratic, and her chakra was nearly depleted, but her eyes remained as stubborn as knives.

She tilted her head back, a trace of blood on her lips, but her smile was defiant: "Kill me."

That was a kind of heroic courage in the face of death.

It's as if even the end of one's life is in one's own hands.

Hiruko gazed at her, a hint of amazement flashing in his eyes—

As expected of a female ninja renowned throughout the ninja world, even when facing imminent danger, she remains beautiful in a sharp and dangerous way.

She did have a hot figure, but what fascinated him even more was her inherent pride.

Despite his exceptional abilities, he became a pawn in the power struggles of the higher-ups, living a life of great renown and dying a death of utter misery...

Ah, is this the destiny of heroes?

In the game of power, even the strongest piece is still just a piece.

"Any last words?"

His voice was deep and slightly playful. "I always keep my word. As long as your request isn't excessive... I can fulfill it."

Ye Cang's body tensed abruptly, and her previously dim eyes suddenly blazed with anger: "Pity me?"

"Heh, I am Pakura of Sunagakure. It's none of the pigs and dogs of Konoha's business to offer me charity!"

Her voice was hoarse yet sharp, like a drawn blade, "Kill me if you want, stop talking nonsense!"

Beiliuhu raised an eyebrow; this was the first time in so long that someone had dared to speak to him like that.

He needs to be careful tonight...
