As the Hokage, Sarutobi has his own dark guard, and the dark ninjas hiding in the shadows saw that the Hokage-sama was poisoned by Naruto, and hurriedly showed up to perform their duties, but because they didn't know the truth, they regarded Naruto as the assassin who assassinated the Hokage.

If they want to treat the Hokage, they can't avoid Naruto, who is squatting next to the Hokage, taking out the serum from the ninja bag and trying to give the Hokage's grandfather a desensitization injection.

Naruto was too close to the Hokage, and the ninjas of the Shadows were afraid of being accidentally injured and unable to use ninjutsu and shuriken, so they could only rush up and try to subdue him with physical arts.

Sensing that a group of masked shadow ninjas jumping out were about to do something to themselves, Naruto didn't want them to interrupt him to inject a special effect desensitization needle into Sarutobi, and quickly raised his hand and snapped his fingers again.

The synthetic organic particle molecules are very light in weight, can float in the air, and have good diffusion, Naruto wears a spraying device on his wrist, and with the flick of his fingers, it is a trigger switch, which can accurately spray allergen fog to a range of tens of meters.

The five shadowy shinobi who flew over crashed headlong into the invisible dust mist in a daze, like mosquitoes sprayed by insecticides, crackling and falling to the ground, struggling to get up, and also losing their mobility due to acute anaphylaxis.

The shinobi in the shadows were all overturned, but the ninjas who were eager to try and wanted to make a move did not dare to approach rashly, and the guides of Sarutobi Asma, Sunset Red and Kakashi Hagi were so anxious that they were afraid of Naruto's strange unknown means, so they could only shout on the periphery.

Ape Fei Asma is the most anxious, the old man who fell to the ground and didn't know whether he was alive or died was his own father, although the old man was outstanding, but he was not young, looking at the appearance of foaming at the mouth and twitching his limbs, it was very similar to the symptoms of cerebral hemorrhage common in the elderly, and he didn't know if he could be saved.

Seeing that her sweetheart was anxious, Sunset Red also felt empathy, and said angrily, "Kakashi, what the hell is going on with your subordinates, why did you assassinate the Hokage?" ”

Kakashi didn't know why Naruto wanted to poison Hokage-sama, so he could only persuade bitterly: "Naruto, calm down, don't do stupid things!" Konoha hasn't done anything to be sorry for you! ”

The pharmacist was stunned, and said in his heart that he was fortunate to stay, and he actually witnessed such a good show, Lord Orochimaru's Konoha collapse plan could be saved, and before Orochimaru made a move, Konoha actually cultivated the second Orochimaru, and helped Lord Orochimaru to cut the ape flying sun in advance!

The shinobi who were present to take the exam, except for the three members of the Maitro team, Sasuke, Sakura, Shikamaru and Iairo, were all trembling, but they were very frightened.

One snap of a finger kills the Hokage, and another snap of a snap of a finger kills five dark upper ninjas, what kind of ninjutsu did Naruto use?

I originally thought that Hinata Ninji was the most perverted shinobi, but I never thought that Naruto was even more terrifying, it can really be described as killing people invisibly!

For a while, the venue for the Zhongnin exam was in chaos.

Fortunately, the special desensitization injection worked quickly, and the serum neutralized the T virus antigen, and the allergy of the ape quickly subsided, and he soon woke up and recovered his health.

Stopping Kakashi and the others who wanted to rush up, Sarutobi Hizashi explained again and again that he was fine, and asked Naruto to inject desensitization needles into the shadow shinobi who had been hit, and then ordered the shadow ninjas who had woken up to escort Naruto away.

Sarutobi also left with Naruto in a hurry, and the middle ninja exam had to be temporarily suspended, and it could not continue until the Hokage-sama gave the result of disposing of Naruto.

……

In an office on the roof of the building, in the tall tower where the Shinobi exam venue was located, Naruto knelt on the ground with an aggrieved expression, and on his head was several large bags that had been slashed out by Sarutobi.

Hokage-sama couldn't think of what to do with Naruto for a while, so he simply beat him up first to vent his anger.

"Don't study such a dangerous ninjutsu in the future!" Sarutobi took a puff of his cigarette and said to Naruto sharply: "Look at it, what a mess it has caused, if something goes wrong and the virus mutates, the consequences are unimaginable!" ”

Under the popularization of the science of medical ninjas, Sarutobi can be regarded as truly understanding the danger of Naruto's "scientific ninjutsu-plague corp. technique".

Although Naruto has made harmless modifications to the virus gene, there is also a law in nature, and that is that "life will always find a way".

Self-destruction is not a normal path of life evolution, and there is a very small chance that vaccines manufactured under strict control may mutate and become virulent, let alone deviant viruses with self-spreading ability.

Once the genetically modified T virus has an unknown mutation during the transmission process and becomes lethal again, the ninja world will really face a Resident Evil that will cause tens of millions of deaths.

"Corn Marseille, Grandpa Hokage, I know it's wrong."

The dejected yellow-haired four-eyed whispered.

Naruto also realized his mistakes, overconfident in his own technology, believing that science can control everything perfectly, which is a common mistake of scientists, and when scientists cause trouble, most of them have this idea before, as evidenced by the biochemical experts of Ambrera and Tony Stark, who made Ultron.

Naruto was actually very cautious, completely erasing the pathogenicity of the T virus, and only using the T virus as a vector for producing antigens. After the outbreak of the virus, only special antigens are produced in the human body without causing any harm, and this special anti-principle makes people have a strong allergy to certain substances.

This strong allergy will also slowly weaken and eventually disappear over time, just as some vaccines must be given every year or they will be ineffective.

The allergen that prompts the onset of the virus is Naruto's artificially synthesized special organic powder, which does not exist in nature at all, and the synthetic molecular formula is unknown to no one except Naruto.

The controllability has been achieved to the extreme, but the possibility of virus mutation still exists, and the danger of Ape Fei Ri Slash is indeed somewhat reasonable.

Of course, scientists have to be reasonable, and since Hokage-sama has said the truth, Naruto is happy to admit his mistake.

"'Scientific Ninja - Plague Company Technique' is listed as an S-level forbidden technique and sealed, and you are not allowed to use it again in the next third round of exam battles, and you are not allowed to use it again in the future!"

Ape Fei Ri Slash thought for a while and gave the result.

Naruto accepted the result calmly, and it was better than he expected, at least it didn't disqualify him from continuing the exam.

It's not easy to deal with Naruto, strictly speaking, Naruto didn't break the rules, creatures like dogs and bugs can be used as ninja tools, and viruses can also be used, not to mention that ninjas are not repulsive to use poison, and they don't think that using poison is despicable, Sanshoyu Hanzo, who is known as a demigod in the ninja world, is a master of using poison, not only is he not despised, but he is also highly respected.

The reason why the "Scientific Ninjutsu-Plague Corporation Technique" is banned is because this ninjutsu is too powerful, and it is also extremely dangerous, and if it is obtained by people with ulterior motives, it will threaten world peace.

If you don't ban this ninjutsu, the result of the middle ninja exam is already doomed in the written test stage, and Naruto, who has spread the virus in advance, can kill everything with a snap of his fingers as long as he scatters allergens around.

Not to mention the lower ninjas who participated, one of the Konoha ninjas counts one, and if they didn't take precautions in advance, they would all be hit and killed by him in seconds.

The allergic reaction is not at all a good physique, and the strong anti-poison ability can be resisted, the allergic reaction is the attack of the immune system itself, which is equivalent to beating oneself, and the stronger the body, the greater the damage to oneself.

Ninjas can get rid of toxins, but as long as the allergen is contaminated and triggers a false alarm from the immune system, the allergy symptoms will explode like a chain reaction, and even if the allergen has been removed, it will have to experience the pain of allergies.

From Naruto's ninja bag, an allergen bomb, an allergen-spreading shuriken, a bee ant carrying allergen powder, and even an allergen potato chip against Akido Dingji were also found......

It can be seen that he has long formulated a set of specific tactics around the "Scientific Ninja Method-Plague Company Technique" to control the enemy.

Only by banning this ninjutsu can it be considered fair to the lower ninjas who take the exam, otherwise there will be no need to fight, Naruto's opponent can suffer less if he abstains early, and of course, it is also good for world peace.
