Red sand dust

The Country of Fire was close to the border between the Country of Taki and the Country of Grass. Jiraiya pressed Naruto Uzumaki's messy hair and sighed:

"It's still too late!"

No matter how unwilling he was, Uzumaki Naruto had to accept the reality.

Jiraiya didn't want Uzumaki Naruto to meet Uchiha Sasuke now, but his plan couldn't keep up with the changes. He accidentally met the "root" ninja and got information about the specific location of Orochimaru.

Unfortunately, by the time the master and apprentice arrived, the building was already empty.

The "Gen" ninjas who were chasing after each other all failed, and Jiraiya, who was not very good at tracking, had no choice.

"Let's go!"

After checking several times, no valuable clues were found, so there was no way to proceed to the next step.

"Sasuke, is he avoiding me?"

"I told you, don't think too much!"

Jiraiya advised earnestly,

"With me teaching you, you won't be worse than him in the future, but now you still need to practice hard!"

Even if they have to hide, Orochimaru and Uchiha Sasuke will not consider the current Uzumaki Naruto. The blond boy who feels that he has made a lot of progress is still a little too arrogant.

"Isn't it enough? After so long, I have become a lot better, right?"

"Well! After a while, I will give you a very important test. If you can meet my requirements, you will be qualified to act alone!"

"Oh well!"

For Uzumaki Naruto, he didn't really have much choice. Besides counting on Jiraiya, who else could help him become stronger quickly?

…

More than ten kilometers away underground, Orochimaru got the news that the pursuers of Konoha Village had retreated, and Jiraiya also left with the Nine-Tailed Jinchuuriki.

"I thought they would last longer, so disappointing!"

There was also some hope in the heart that Jiraiya would come to the door and let him try the forbidden technique to kill the Hokage Sandaime. Unfortunately, he still overestimated them.

In his heyday, Orochimaru had the confidence to face all challenges and evade pursuit, but he just didn't want the endless harassment to affect the progress of the experiment.

Putting aside these unnecessary trivial matters, Orochimaru walked straight into a laboratory that had been tidied up a long time ago. On the experimental table in the middle, an unconscious Deidara was lying on it.

Not far away, Yasushi Kabuto put down his scalpel and took off his plastic gloves.

"Kabuto, does the result prove it?"

"Just as you expected!"

Kabuto Yakushi cleaned the water mist on his spectacle lenses and answered with great conviction,

"More than a quarter of the cell samples are the same as Zukon and Ukon!"

"really!"

Why are there always strange "backdoors" planted in the bodies of our own personnel for Dawan to use, but no abnormalities can be found?

The fundamental reason is that these strange cells pretended to be mutated after being stimulated by the cursed chakra, and they escaped Orochimaru and Yakushi Kabuto's multiple tests.

Even though Daimaru captured Ukon and mastered Sage Mode, Orochimaru still did not consider the possibility of the curse seal being exploited.

The fundamental reason is that the senjutsu chakra refined by different sage modes all contain the characteristics of the creator, and it is very difficult to coexist.

Forced integration will only lead to serious conflicts and even the risk of death.

This is a completely different biotechnology than what we have mastered.

No, it shouldn't be biotechnology. This kind of technique doesn't quite comply with some basic principles of biotechnology.

Orochimaru, who had once partnered with the Red Sand Scorpion, instantly recalled the genius puppet master from the Hidden Sand Village.

"Puppetry? It turns out that you have inherited the legacy of the Red Sand Scorpion!"

He stretched out his fingers and gently pressed them on Deidara's arm covered with light golden lines. A small but strong force was passing through his fingers, making Orochimaru feel that familiar sense of threat.

The news of the death of the Red Sand Scorpion has long been revealed, but there is no news about whether Chiyo's grandson left something good.

Having mastered the technique of making human puppets, one must also have extremely advanced ability to manipulate the human body.

As his right-hand assistant, Kabuto Yakushi explained in detail:

"If there is no problem with the information provided by Lord Orochimaru, then it can be determined that the person targeted by Daimaru is in a state between a normal ninja and a human puppet! Using living people to create adult puppets is indeed a good technology , However, this 'semi-finished' human puppet created by Daimaru may be more valuable!"

"What a good idea! No wonder it can be so hidden in our bodies without being discovered!"

Orochimaru looked at the report handed over by Yakushi Kabuto with great interest.

"First of all, we should think about how to remove Daimaru's 'backhand', and then try to see if we can counterattack..."

The leakage of one's own intelligence this time sounded the alarm for Orochimaru.

Even if you are not afraid, it is not a good thing if your whereabouts are always noticed.

"It is extremely difficult to completely remove these strange cells. Their activity is very poor and they do not show power unless necessary. They are spread all over the body and have almost become a part of the body. Unless their weaknesses are found, there is nothing you can do about them!"

"Is there really no way?"

Kabuto Yakushi hesitated for a while and then shook his head:

"They are like invading bacteria and viruses. Surgical removal is definitely unrealistic. They can only be killed with 'specific drugs', and..."

"what else?"

"I don't know how to describe it. This kind of cell invasion is actually benign! They continue to integrate into normal cells, become part of the body, and stimulate the potential of other cells. The two synergistically strengthen and improve together! If there is no master, I I think this kind of 'parasitic microorganism' will become a good partner of mankind, especially ninjas..."

When he first discovered this phenomenon, Yakushi Kabuto was also surprised.

There are no parasitic secrets. In addition to the curse seals that one has mastered, such as the parasitic bugs of the Aburame family, they actually count.

However, composite cells like Daimaru that have integrated regenerative nuclei are so "selfless" and "sacrifice themselves for others" is almost unheard of.

But Daimaru doesn't look like the kind of guy who only does good deeds without asking for anything in return. The backdoor of some mental possession is completely unworthy of the value of such a magical cell sample.

"After ruling out all the impossibilities, the rest is actually more obvious!"

Pharmacist Kabuto pushed up the glasses frame on the bridge of his nose and said very firmly,

"This thing should be the puppet version of the 'curse seal'. Even if there are differences, the functions are similar!"

The biggest difference is that the curse seal is rooted in the soul, while the regeneration core is bound to the body.

Whether it's a curse mark or a regeneration core, there should be a way to completely remove it, but it's definitely not easy.

"interesting!"

Orochimaru, who increasingly feels that the skills Daimaru has mastered are valuable, said,

"Isolate a batch of cell samples first and try their properties!"

Orochimaru, who was able to extract the curse seal from Jugo's body for his own use, was confident that he could also turn this strange parasitic cell into his own secret technique.

All unknowns are the objects of Orochimaru's research, including Daimaru himself.
