Nagato's cultivation lasted for several days.

Thanks to the huge chakra attached to the Uzumaki Clan's physique, coupled with the fact that the ice magic is indeed easier to control, and there is also a large snake pill beside him to give ideas and guide at all times, and the big stick in his hand always knocks down when the magic power in Nagato's body is uncontrollable, dispersing the energy of the rampage......

In short, under the super resilient body, Nagato finally completed the fusion of ice magic and chakra in just a few days.

In other words, Nagato has completed the cultivation of the immortal mode!

"Drink!"

With a low snort, he mobilized the magic power in the Eye of Darkness and controlled the fusion with the chakra in his body.

"Open!"

Suddenly, he opened his eyes, and it was pitch black, as if the black eyes of the opposite of white eyes appeared in Nagato's eye sockets.

There is no way, once a lot of magic is used, Nagato's eyes will become like this, and they will look a bit like the black eyes of the reincarnation of the filthy earth.

But the name Eyes of Darkness lives up to its name.

A layer of dark blue chakra surrounds Nagato's body.

This is the energy after the fusion of ice magic and chakra, which can also be called immortal chakra.

"You need to learn the fighting methods of Bing Dun, and I have prepared this information for you. Orochimaru said.

"Hmm. ”

Nagato's immortal mode cultivation was finally successful, and Orochimaru was also very happy.

Because through the study of Nagato's senjutsu chakra, it is a little easier to control than the inter-pillar senjutsu chakra.

The basic research on the spell seal has long been completed, but the success rate of using inter-column cells and inter-pillar immortal chakra is too low, and too few experimental subjects survive.

Therefore, Nagato's senjutsu chakra is what Orochimaru has high hopes for.

And in fact, it was not as expected by Orochimaru.

The chakra fused with the magic of ice seems to have a great harmony with the human body, and the new version of the spell mark is no longer a matter of how much the success rate has increased, but as long as you don't have no water attribute, only the special case of fire attribute, then the success rate of the new version of the spell mark is quite high.

In particular, the success rate of test subjects with water-attribute chakras is 100%.

……

Orochimaru's laboratory, outsiders are not allowed to enter.

Especially the recent research on the spell seal, even the other people of the miracle flash have not come in.

Liuli is not available, and the others are not paying attention.

However, some of the darkness that exists in it is also the willingness of Orochimaru to let them in and see, and it just so happens that they will not come.

During the war, there were always some people who lost their bottom line, so they were used by Orochimaru for experiments.

Despite this, Orochimaru knows that the vast majority of people are still against it...... Well, so do it quietly, or they will know it, and they will use it anyway, and few people will care about how they got the spell seal.

"It worked. ”

Orochimaru, whose eyes were full of excitement and fanaticism, stared at a female ninja on the test bench.

The female ninja was Orochimaru's subordinate, and after going through the trial phase, Orochimaru was naturally the first to apply the finished product to his subordinates.

"Try your newfound powers!"

"Yes! Orochimaru-sama!"

The female ninja trembled with excitement, then forcibly calmed down and began to activate the power of the spell seal.

As Orochimaru's brain-dead fan, she was saved from despair and became a female ninja who was the tool in Orochimaru's hands, and she began to slowly activate the power of the curse seal.

In this matter, she had to take her time, because she knew that her Orochimaru-sama would definitely have to watch carefully.

A black spell mark in the shape of a three-hook jade on his neck was activated, and a dark blue fairy chakra began to flow out.

Although it seems that Nagato only took a long time to fuse ice magic and chakra, the fused senjutsu chakra is not an easy thing for ordinary ninjas to use.

The Immortal Chakra formed by the fusion of ice magic with chakra will cause a great burden on the user's body and will erode the user's body.

But at this time, another thing that Orochimaru added to the spell seal came into play.

Intercolumnar cells!

The cells between the first Hokage Senju Pillars, as a controlling force, life force, and something that has a strong corrosive power on other cells, were added to the spell seal by Orochimaru.

In this way, it can not only limit the erosion of the immortal chakra on the body, but also allow the user to better withstand the immortal chakra.

And the fairy chakra also has an inhibitory effect on intercolumnar cells.

The two restrained each other and complemented each other, so there was the latest version of the spell seal.

Bang Bang –

The sound of a strong heartbeat is so obvious in the quiet place of the laboratory.

The first female ninja to use the new version of the spell seal, through the thin clothing on her body, you can see that on her left chest, a blue magic pattern began to spread to her left arm, and finally formed a strange snowflake-like pattern on the back of her left hand.

Then, the blue mana pattern dimmed and turned black.

And at this time, the temperament of the female ninja has changed drastically.

Originally, there was only an ordinary mid-ninja level chakra, not to mention, the peaceful chakra aura has become deep and cold, like an extremely cold iceberg.

ClickClick......

Frost began to condense in her left hand, and an Ice Tai Knife slowly took shape.

But Orochimaru frowned.

The speed of condensing weapons is too slow...... Is it because of unskillfulness?

You must know that Liuli is a lot of ice martial arts when you call it casually.

"Attack me and try. ”

Orochimaru said.

Hmmm——!

Unlike the female ninja who was very excited in the face of Orochimaru before, she was very decisive after activating the spell seal, and Orochimaru slashed off the Ice Tai Knife in her hand as soon as she finished speaking.

There is a layer of dark blue fairy chakra attached to the blade, which gives Orochimaru a very dangerous feeling.

But Orochimaru didn't dodge or dodge, and carried the knife stiffly.

Almost unhindered, Orochimaru's body was slashed diagonally in two from his neck.

The female ninja face-to-face was covered in blood, but she didn't have any expression, as if waiting for Orochimaru's next instructions.

"Not bad. ”

A brand-new Orochimaru emerges from the stump.

Just now he used his own body to test the power of this knife, as for the result...... Quite satisfied!

Not only for the power of this knife, but also for the mentality of the female ninja in front of him.

You must know that this female ninja is her brainless fan, and if Orochimaru usually lets her attack herself, it is estimated that it will take a long time.

But this time, he slashed it without hesitation.

There was no nonsense, no caution, no awe and concern for him, as if the whole heart suddenly became calm.

"Special effects? That's good. ”
