Human Experimentation!

Konoha Prison?

Tang Ping looked at Uchiha Shizuka, who was leading the way, somewhat puzzled.

She and Uchiha Shota were both staunch members of the Mei Faction, so letting her in on some information would be beneficial and bring considerable convenience.

"Where do you think the test subjects at Konoha Hospital come from?"

Seeing Tang Ping's look, a trace of mockery appeared on Uchiha Shizuka's face.

The Will of Fire? Not even dogs would believe it!

No matter how pretty the words sounded on the surface, they could not fool the major ninja clans.

Only low-level ninjas and a handful of others firmly believed in the Will of Fire spoken of by the Third Hokage.

Especially a certain clan head's son, who had been completely brainwashed by them.

"I see!"

Tang Ping now understood where the hospital's experimental products came from.

Medical Ninjutsu required a large number of test subjects for practice.

At first, fish were used for training. Later, patients naturally had to be used to practice Medical Ninjutsu.

Of course, villagers and hospital patients could not be used for practice, so serious criminals in prison "voluntarily" devoted themselves to medical research.

Root's experiments also required people to carry them out.

That was why Uchiha Shizuka had brought Tang Ping here when he wanted to conduct human experiments.

Not only were there ample test subjects, but it was also safer and more secretive.

Upon entering the prison's interior,

Tang Ping finally got a look at its defensive forces.

All the guards were Uchiha.

Several Jonin were stationed there at all times. Combined with the mechanisms and traps, even a Kage-level expert attacking the prison could be held back.

After winding through the maze-like Konoha Prison for half a day, the two finally stopped.

"Shizuka Captain!"

A female Uchiha guarding this cell opened the cell door for them.

Uchiha Shizuka commanded a company of female ninjas.

That was right, her position was captain of the Fourth Company of the First Battalion of the Military Police Force.

The Military Police Force had four battalions in total!

Each battalion had four companies, each company had four squads, and together with several administrative divisions, they formed a complete department—a world unto itself.

At the same time, the positions in each battalion were tied to their respective branches of the clan.

After entering the cell,

Tang Ping saw a male prisoner missing his right hand, bound to a torture rack within a metal-barred enclosure.

"This is a ninja captured earlier. For now, he is the only suitable target I have!"

Uchiha Shizuka began her introduction.

A ninja!

That was an essential requirement for the experiment.

No one knew whether the Rebirth Potion would have the same effect on ordinary people as it did on ninjas.

After all, there was one enormous difference between ninjas and ordinary people.

Chakra!

This thing meant that although ordinary people and ninjas looked the same on the outside, they were fundamentally two different kinds of beings.

That was why the experiment required a ninja rather than merely an ordinary person.

"It's fine. We probably won't need that many test subjects!"

Tang Ping did not think he needed many.

Perhaps one person would be enough.

He was not worried about the potion's effects. The key was determining the dosage. Experiments in that area should not consume test subjects too quickly.

As for whether using people as test subjects was cruel?

Sorry, but in this twisted ninja world, no one cared.

As long as they were not from their own village.

The reason Orochimaru would defect in the future was not primarily because of human experimentation.

Every major ninja village had done plenty of that. No one cared.

The real issue was using people from one's own village as test subjects. That was unforgivable.

If he had used people from other villages as test subjects, then with Orochimaru's status, it would not have been an issue at all.

Now you understood how the ninja world viewed human experimentation, right?

As long as they did not use their own people, it was fine.

That was also why Uchiha Shizuka had brought Tang Ping to the prison for the experiment instead of conducting it outside the village.

It simply was not a big deal!

Naturally, Tang Ping would not play the saint either. His bottom line was simply not using "innocent" people as test subjects.

He would naturally show no mercy toward a ninja like this, one guilty of every imaginable evil.

"I'm starting!"

Entering the metal-barred enclosure, he carefully injected the potion into the unconscious man's body.

The reason he had Uchiha Shizuka present to watch this experiment

was not only so she could witness the potion's effects firsthand, but also so she could keep things under control.

If an accident truly happened, an Elite Jonin would be enough to ensure their safety.

Tang Ping had no intention of following in the footsteps of those fools who got Counter-Killed by their test subjects.

He was not Orochimaru. Not only did Orochimaru possess Kage-level strength, but his survival skills were also maxed out.

After finishing the injection, Tang Ping withdrew from the enclosure and quietly watched what happened next.

Thump, thump!

Heartbeats like drumbeats rang out.

It had begun!

The Rebirth Potion's effects were taking hold.

Tang Ping had calculated the injected dosage.

Animal injections and human injections, ordinary people and ninja injections—these were all issues that needed to be resolved.

If the dosage was wrong, there would be only one outcome.

Bang!

They would burst like balloons.

Moreover, the Rebirth Potion was extremely expensive.

Just the single tube Tang Ping had injected cost nearly ten million ryo.

That was the cost price!

The dosage used on laboratory mice might not even be one percent of what was in that tube.

The reason Orochimaru would cooperate with Root in the future

might also be because experimental funding was so costly that he could not continue without working with them.

"Ah!!"

"So hot!"

"What's happening to me?"

The prisoner, originally unconscious, woke under the potion's effects and let out wave after wave of screams.

There was no need to worry about the sound getting out.

This was a prison!

Its soundproofing was definitely professional-grade.

Tang Ping's gaze remained fixed on the man's severed right arm.

He had deliberately chosen this Genin as a test subject because the man's right arm had already been severed when he was captured.

Fine strands of flesh burst through the previously healed wound and began to wriggle as they grew.

The two outside the barred enclosure were not frightened by this bizarre and terrifying sight. Instead, they were filled with anticipation.

Because it represented one thing.

The Rebirth Potion also worked on ninjas.

Once they confirmed they were on the right track, all that remained was improvement and experimentation.

"Pain!"

"It hurts so much!"

"Someone save me!"

The prisoner screamed and struggled wildly.

Seeing his movements grow increasingly violent and the ropes binding him pull tighter and tighter, Tang Ping spoke.

"Aunt Shizuka, make him quiet down!"

He had anticipated the pain long ago.

Just like the Natural Power Potion, the medicinal effect had been compressed to erupt over a short period. Of course it would be painful.

What he had not anticipated was that the pain would clearly exceed the limits of human endurance.

Even Chakra could not withstand it.

Step!

Uchiha Shizuka stepped forward. Her pitch-black eyes abruptly turned blood-red, and three tomoe like tadpoles appeared within them.

Sharingan!

It was also the Kekkei Genkai that the Uchiha Clan took pride in.

Its effects were powerful and versatile, and it could even evolve from low to high levels. It was practically perfect.

If not for the side effect of affecting one's mind.

Genjutsu: Sharingan!

Uchiha Shizuka used a Sharingan-exclusive Genjutsu.

Soon, the struggling prisoner gradually stopped moving, leaving only the flesh buds on his right arm to continue wriggling.

Half an hour later!

The man's missing right arm had now taken on a rough shape.

Just as Tang Ping thought it had succeeded,

Boom!

The prisoner's body exploded directly, leaving only blood and flesh splattered across the enclosure.
