Rebirth Potion and the 'Working Stiff' Kakuzu!

Inside the laboratory!

A mouse with one hind leg severed had now fully recovered. Aside from having lost some fur, it was no different from how it had been before.

Although Uchiha Mei could not see, her other senses remained sharp. Naturally, she could tell that Tang Ping had not swapped out the mouse in her hands.

"H-How is this possible?"

The despair in her heart had vanished. She kept feeling the mouse in her hands as she muttered to herself.

As a ninja, let alone touching a mouse, she could touch even a snake without changing expression.

"Why wouldn't it be possible?"

"You're too narrow-minded!"

"Nothing is impossible."

Tang Ping's tone was confident.

The facts were right in front of her. There was no way she would refuse to believe now.

Besides, he did not think this achievement of his was anything remarkable.

In the future, that Byakugan Wolf Obito would lose half his body and still be saved by Madara, the master of playing it safe, using White Zetsu. Then there was Orochimaru's cloning technology... All of it was far more impressive than his result.

Those were actual techniques, while he had only managed this by cheating with his blood.

Without the special blood in his body, there was no way he could have created this kind of 'Rebirth Potion.'

Rebirth Potion!

Anyone who used this potion would be reborn, so the name suited it perfectly.

"When can I begin?"

Uchiha Mei turned her head and asked urgently.

During the time she had lost her eyes—she had spent the first few days secretly receiving treatment outside while news of the incident was sealed off, rather than only losing them today—she had suffered terribly.

Now, she did not want to wait even one more second.

"Not yet." Tang Ping shook his head and explained, "So far, we've only tested it on animals. We don't know whether there are any side effects, and most importantly, we need to determine the dosage!"

Hearing that, Uchiha Mei calmed down and asked:

"Then is there anything you need my help with?"

With this successful example, she no longer had to worry about losing the light forever. Naturally, her patience returned as well.

Endurance was an essential quality for a ninja.

"I need you to have someone post a commission at the Exchange Station for a Summoning scroll. At the same time, collect... these materials, and find test subjects!"

Tang Ping stated his requirements.

"Alright!"

Uchiha Mei agreed without the slightest hesitation.

As the former clan head's granddaughter, her influence was beyond imagination.

Previously, she had been too devastated to do anything. But once she truly decided to act, neither manpower nor money would be a problem.

Not long afterward.

A designated commission appeared at an underground Exchange Station.

The Exchange Station!

It was an intermediary platform with traces spread across the entire ninja world.

Any kind of mission could be posted there, without any restrictions.

A mission reward of thirty million ryo!

That price was already outrageous.

Even the bounties on some leaders of small ninja villages might not be that high.

Inside a secret Exchange Station in Rice Field Country.

Bang!

A corpse was thrown onto the counter.

A figure hidden entirely beneath a cloak, with eyes like mung beans, silently counted the money in his hands.

"Lord Kakuzu, would you be interested in taking a thirty-million-ryo mission?"

The Exchange Station manager behind the counter asked cautiously.

"Thirty million ryo?"

Kakuzu, who had been counting money, instantly felt that the cash in his hands no longer seemed so appealing.

After working hard for an entire month, he had finally hunted down the jonin in front of him and collected a bounty of two million ryo. Now there was a mission worth thirty million ryo. How could he not take it seriously?

"Yes. The other party specifically requested that you complete it..."

The manager did not understand why anyone would dare cooperate with such a dangerous figure, but he would not ask unnecessary questions. He merely did his job.

"I'll take the mission!"

Kakuzu was not afraid of difficult missions. What he feared most was insufficient pay.

At such a high price, even assassinating one of the Five Great Ninja Villages' Kage was not out of the question.

Bang!

The moment the manager heard that Kakuzu was willing to accept, he immediately used the Summoning Technique to retrieve the mission scroll.

After taking the scroll handed over by the other party and confirming that its seal was intact, Kakuzu opened it and checked the mission details.

The mission was extremely simple.

He was to head to Drowning Swamp and retrieve a Summoning scroll from there.

The employer had provided some intelligence. The Summoning scroll was guarded by a powerful giant lizard that was skilled at...

With this information, Kakuzu was highly confident that he could complete the mission.

The only troublesome part was that, after completing the mission, he was not to hand the item directly to the employer, but instead deliver it to a small merchant caravan.

Still, it did not matter. The payment had already been deposited in the Exchange Station, the intermediary platform, so there was no need to worry about the other party refusing to pay.

After reading the mission scroll and tucking it into his clothes, then carefully placing the counted money into a cash box, Kakuzu slowly left the underground Exchange Station.

On the other side!

Tang Ping was busy every day.

Not only did he have to focus on all aspects of his own training, he also had to develop new techniques, research potions, and more. He wished he could split himself into several people.

Right!

There was a ninjutsu that could achieve that effect.

The Shadow Clone Technique!

This B-Rank Ninjutsu was an essential cheat for transmigrators.

Although Uchiha Mei could obtain this ninjutsu, she could not teach it to him.

Aside from the village's and clan's restrictions, there was also the difficulty of learning it.

At minimum, one had to be a jonin to master it.

As for Tang Ping's combat strength, Taiyi's presence had allowed it to advance by leaps and bounds, making him far stronger than an ordinary chunin.

But in terms of his own strength alone, he was still far from jonin level.

In anime, jonin were everywhere, Kage-level experts filled the streets, Super Kage were nothing unusual, and only those at the Six Paths level could come out and strut around.

But in the real ninja world, one understood just how unrealistic that was.

Even jonin who were merely background characters were still unquestionably big shots in every major ninja village.

Among Konoha's more than ten thousand active-duty ninja, there were fewer than two hundred jonin. That showed just how rare they were and how difficult promotion was.

So for Tang Ping, a genin who had only just graduated, wanting to learn a jonin-level ninjutsu like this was simply wishful thinking.

Of course.

If he were some Nine Tails Jinchuriki with Uzumaki blood, it might not be impossible to consider it.

(Naruto: You might as well just say my name!)

Sadly, he was not. So he could only act as a 'Time Management Master,' carefully allocating his daily time while struggling miserably.

His dream was to lie flat, after all.

Yet now, not only could he not lie flat, he had even become a 007 worker. The bitterness in his heart was easy to imagine.

It was all Danzo's fault!

The best news was probably that he had made rapid progress in developing new techniques.

Though he was far inferior to those freaks blessed with protagonist halos, he could at least be called a 'genius.'

Tang Ping lacked neither imagination nor foundational knowledge, and Minato Namikaze guided him in practical operation and technique. Naturally, everything went smoothly.

Once he had this exclusive ninjutsu, his strength would soar.

He had also extracted several doses of Rebirth Potion. Once they underwent human testing, they could officially be put into use.

As for how to conduct the tests?

Tang Ping himself definitely could not do it, but with Uchiha Mei making arrangements, it was another matter entirely.

Today was also the day of the experiment.

He arrived at an unexpected testing location.
