The researcher walked up to him with a pale face, emaciated cheeks, bald hair, and a deep layer of dark circles around his eyes, as if he had been wearing smoky makeup.

His eyes were bloodshot, and his eyes were a little abnormal, faintly crazy.

This researcher's name is Tayama Asasa, and he is Yusuke's most powerful subordinate at the Konoha Research Institute except for Dou, and he is very obsessed with the study of biological sciences, and he is also the person who is most feared by Feidan.

Yusuke raised his hand slightly and introduced Tayama Asasa to everyone: "This is Dr. Asasa and the director of the Biology Department of the Konoha Research Institute. Soon he will present the latest research results of the institute. ”

"Plus, there's going to be some gore with his demo. Originally, I also wanted to use animals instead, but Asa insisted that she wanted to show everyone the results, and it was useless for me to persuade them. Yusuke added that he didn't want people to think of him as a pervert who abused his subordinates.

After Yusuke finished speaking, Asa stretched out his right hand, revealing a spell mark on his wrist.

"Everyone, please see, this spell mark is called "First Aid Seal", when the owner of the spell mark is seriously injured, just use Chakra to activate the spell seal, and the powerful healing power of the spell mark can be activated." Asa said in a hoarse voice.

As soon as the words fell, Ah Kasa took out a kunai in the surprised eyes of everyone and stabbed it fiercely in his chest, and blood splattered for a while.

Ah Kasa is worthy of being the first ruthless person in the research institute, and this time the kunai stabbed very deeply, and even penetrated his lungs. After the stabbing, Asa coughed violently, and a lot of blood spilled from his mouth.

Most of the ninjas present were accustomed to seeing life and death, and although they were surprised by Akasa's behavior, their expressions were still very calm. However, some civilians were so frightened by the scene that they screamed.

Soon, something unbelievable happened to everyone present, only to see a chakra with strong vitality flowing from the curse mark on Asa's wrist to the location where Asa was injured.

In just a few tens of seconds, not only did the injury on his chest recover as before, leaving only a scar, but even the coughing caused by the damage to his lungs stopped.

Everyone could also see that this curse seal not only repaired the external injury, but even the damage to Asa's lungs. It can be seen that even if the internal organs are damaged, they can be treated quickly.

"As you can see, I've recovered from my injuries now. However, although the "First Aid Seal" is powerful, once activated, it will consume all of its vitality, and if you need to use it again, you will need to inject a special replenishment solution. ”

After speaking, Agasa showed the darkened spell mark in his hand in front of everyone's eyes, and then took out a syringe and injected the replenishment solution into the spell mark.

Then, the color of the spell seal gradually returned to its original state.

What Asa shows is naturally Yusuke's development of the "Seal of Life". It's just that later, the researchers of Asa and the Konoha Research Institute made a lot of changes on the basis of the "Seal of Life".

The modified "First Aid Seal" does not have the same powerful healing power as the "Life Seal", but it can be stored on the user's body and triggered when needed.

And after using it, inject the replenisher solution again to replenish the vitality in the spell seal, and you can reuse it many times. This supplement is a diluted version of the "Intercolumn Cell Fusion Solution".

In addition, the "First Aid Seal" consumes much fewer intercolumnar cells than the "Life Seal", and the medicinal power is relatively mild, which is more suitable for large-scale promotion and use.

Later, Agasa introduced the "First Aid Seal" to everyone in detail, and let everyone present know the applicability and ease of use of this spell seal, and everyone present showed happy and excited expressions.

In the war of ninjas, the casualty rate is very high, which is the most headache for all ninja villages.

Now with the "First Aid Seal", Konoha's ninja is equal to one more life, and the probability of surviving on the battlefield has been greatly improved.

"I didn't expect that the research institute had not yet been built, and there would be such significant results. Worthy of being the chief consultant! ”

"Yes, with this spell mark, even if Yun Yin and Wu Yin join forces, there is nothing to fear, this time I must give them a little color to see."

For a while, there was a lot of discussion in the conference hall, and everyone was even more in awe of Yusuke.

Obviously, this young chief advisor is not only very good at his own strength, but also has great ideas in the development of ninjutsu.

"With this spell seal, isn't it possible for our squad to be free from medical ninjas, and all of them are combat members. In this way, it will also increase our combat effectiveness in disguise? The patriarch of the Inuzuka family asked.

Nara Lujiu on the side shook his head when he heard this: "This spell mark is a one-time use, and after use, you need to replenish the energy in it, or is it more suitable for life-saving use at critical moments." In the long war, the medical ninja is also an indispensable force to treat the wounded with non-fatal injuries. ”

Yusuke added, "The head of the Nara family is right. In addition, the amount of refill consumed by the "First Aid Seal" is limited, so it is impossible for every ninja to have one. ”

"During this war, the staff of the research institute will apply a "First Aid Seal" to every ninja who goes to the battlefield, but only ninjas who perform extremely dangerous tasks can apply for additional replenishment from me."

Regarding Yusuke's explanation, everyone also felt that this distribution was very reasonable.

At this time, the third generation said with a serious face: "Yusuke, this curse seal is very important to the village, and the secrecy must be done well, and the decision must not fall into the hands of other villages!" The research institute must be under the protection of the shadows. ”

Hearing the words of the three generations, Yusuke smiled: "Three generations of adults, don't worry, the confidentiality work has been fully prepared, so you won't bother with the dark department." ”

Of course, Yusuke will attach great importance to his own intellectual property rights. He modified the Root Organization's "Tongue Curse Root Seal" so that this spell mark could not cause damage to the recipient, but it could force the recipient to not reveal any confidential information in the Institute, which was a mandatory confidentiality agreement.

Looking at Yusuke, who was already in front of him, the three generations knew that if they wanted to get involved in the Konoha Research Institute, it was impossible for the time being.

However, with this "First Aid Seal" in hand, Yusuke will inevitably become a hot figure in Konoha, and it will be even more tricky in the future.

After all, whether it is a ninja or a family, everyone hopes that they or their own people can have such a powerful means of saving their lives.

After using the "First Aid Seal", if you want to continue using it, you must go to the Konoha Research Institute to apply for a new replenishment, which naturally requires Yusuke's approval.

After displaying the "First Aid Seal", everyone began to formulate a battle plan against Yun Yin and Wu Yin.

After the final discussion, Yusuke led the northern front to deal with Yunyin's attack.

Jiraiya, on the other hand, is the commander of the eastern front, dealing with the ninjas of the fog from the sea.
