Naruto: Can't learn ninjutsu? I'll just practice immortality!

The key is that such a light and thin scale is stronger than ordinary steel.

The employee of the ninja tool shop has seen the scales of those giant summoning beasts.

Most scales are of good quality, and there are scales that are harder than steel, but the weight of those scales is often too high and difficult to use.

But the scales sent by Asakawa Naoki are different. This kind of scale with low density and high strength is simply natural armor.

Just a little polishing can be used as armor for ninjas.

But Asakawa Naoki's idea is to make these scales into something like talisman paper, which is really a bit difficult for them.

If it is an ordinary rain ninja, even if the other party is a senior ninja, they will directly refuse.

But the person in front of him is Akiba, the leader of the Hidden Rain Village. His current reputation is even stronger than the former "demigod" Salamander Hanzo. How dare they refuse?

"Can't do it?" Asakawa Naoki said with some disappointment.

"It's not that we can't do it, but we can't do it as the adults asked. At present, we can only make some semi-finished products." The employee of the Ninja Tool Shop said truthfully.

"Semi-finished products? Let me see." Asakawa Naoki said with interest.

"Yes! Please take a look, sir." The employee of the Ninja Tool Shop took out a stack of talisman paper and handed it to Asakawa Naoki.

When I first got it, it seemed to be no different from the talisman paper of the detonating talisman, but if I touched and folded it carefully, I would find that the hardness of this talisman paper was much higher than that of the detonating talisman paper, and it was as hard as iron sheets.

"Those scales are too hard. Even if they are made into talisman paper, it is difficult to soften them. If you want to really make a finished product, I'm afraid it will take some time." The employee of the Ninja Tool Shop explained.

"Then you continue. I'll take these semi-finished products first." Asakawa Naoki said, picked up two stacks of special talisman paper and left first.

Not long after returning to the office of Yuyin Village, Asakawa Naoki's real body had arrived.

After receiving the semi-finished talisman paper, Asakawa Naoki checked it. Although it was indeed a bit hard, the material should meet the requirements of bearing four prohibitions.

Controlling the incarnation to continue working, Asakawa Naoki himself came to the secret room where the incarnation practiced.

After arranging the barrier array, Asakawa Naoki adjusted his mentality and mana again, and finally began to refine the four-pattern talisman.

For Asakawa Naoki, who can refine sixteen four-pattern spirit weapon flying swords at the same time, the four-pattern talisman is naturally not a problem.

However, the talisman and the method of refining weapons need to be guarded against arrogance and impatience. He has just broken through the middle stage of refining qi into spirit, and his mentality needs to be adjusted.

Not long after, Asakawa Naoki finally started to refine the four-pattern talisman when he was calm.

With the experience of refining the four-pattern flying sword, the four-pattern talisman was refined very smoothly.

The reason why it couldn't be refined before was because the talisman paper couldn't bear the power of the four prohibitions. Now that it has been replaced with Xiaobai's scales, the strength of the talisman paper itself has naturally become a problem.

However, because the difficulty of refining is very different from the three-pattern talisman, Asakawa Naoki can only refine it one by one, and it took several days to refine all two stacks of special talisman paper.

Looking at the dozens of four-pattern talismans in front of him, Asakawa Naoki couldn't help but feel relieved that the four-pattern talismans were finally made.

"Next, it's time to ignite the gas fire."

Asakawa Naoki controlled the condensed mana to continue to compress it according to the method of Samadhi True Fire, as if a trace of invisible fire was born from the compressed mana.

The next moment, Asakawa Naoki only felt that the mana in the meridians was burning, and the speed was extremely fast, as if the next moment it would burn the dantian.

Fortunately, Asakawa Naoki was well prepared at the moment when the invisible fire was born, and he attached more than a dozen newly refined four-pattern talismans to his body.

"Soft Water Meridian Protection Talisman!"

"Ice Protection Talisman!"

"Weak Water Pill Protection Talisman!"

"..."

At the moment when these four-pattern talismans took effect, Asakawa Naoki felt his heart and soul turned cold, and even the meridians and Dantian burned by the fire of mana were not so hot.

"I didn't expect that the Qi fire would instantly ignite all the mana in my body. Even now, I can't resist this kind of flame, and it would be difficult to resist it."

"Fortunately, I prepared these protective talismans before igniting the Qi fire."

Under the suppression of more than a dozen water-based four-pattern talismans, the Qi fire, which was originally extremely dangerous, was suppressed to the point that it could not raise its head. After burning the mana in Asakawa Naoki's body, it did not hurt the meridians and Dantian at all.

After the mana in the body was burned out, Asakawa Naoki felt as if his body was hollowed out.

Although the strength of the physical body remained, there was no mana at all.

At this moment, it is not an exaggeration to say that he is at his weakest.

However, when he saw the invisible fire in his dantian through his inner consciousness, Asakawa Naoki feltI feel that everything is worth it.

"Hey, Asakawa boy, what kind of ninjutsu did you practice just now!" Yin Jiuwei said with some fear.

Since its birth, it has nothing to fear except the Six Paths Sage, Senju Hashirama and Uchiha Madara.

After all, as a tailed beast, the Nine-Tailed Beast is a kind of energy body.

Even if it dies, as long as the Nine-Tailed Chakra does not dissipate, it will eventually gather again to form a new body.

But the Qi Fire in front of the Nine-Tailed Beast makes it feel fear.

If it is burned by this kind of flame that can burn mana, it may take hundreds of years to condense again.

Fortunately, when Asakawa Naoki used the talisman to protect the Dantian just now, it also protected it, otherwise it might be burned out along with Asakawa Naoki's whole body mana.

"This is Qi Fire, a flame specifically for energy." Asakawa Naoki explained.

"The flame that specifically targets energy is really the nemesis of our tailed beasts." Yin Jiuwei said helplessly:

"You didn't develop this kind of flame just to deal with our tailed beasts?"

"Don't worry, can't you feel my malice?" Asakawa Naoki smiled and said, "Besides, it's not just you tailed beasts who have chakra, all ninjas in the ninja world have chakra, okay."

"That's true, I'm going to rest, don't disturb me if you have nothing to do." Jiuwei said and lay down in Asakawa Naoki's dantian and stopped talking.

In fact, Asakawa Naoki didn't think that the fire of air targeted the tailed beasts very much, and the fire of God in the Samadhi True Fire was the most targeted at the tailed beasts.

After the chakra was burned out by the fire of air, the tailed beasts could still be condensed again, and it would take no more than a few hundred years.

But if the soul and will were burned by the fire of God, it was uncertain whether the tailed beasts could be condensed again.

"Restore your mana first."

Asakawa Naoki began to absorb the natural energy around him and refine it into mana.

Without some magic power in his body, many of his methods could not be used. Although he could defeat a senior ninja with his physical body alone, he felt insecure without magic power.
