My name is Kayn Uchiha and I will be a Darkin

How could this brat know!

As soon as Orochimaru heard someone mentioning Itachi, Itachi's younger brother, or mocking him, Orochimaru wanted to kill him instantly.

But when he thought of the unfathomable little ghost in front of him, he suddenly calmed down.

In fact, even if he really made a move, Kayn is completely worthwhile.

The reserve of magic power has come to about [-], including the development of various unexpected dark magic, plus the finishing technique of splitting shadow!
Kayn now possesses the strength of an elite johnin, although he has no certainty of winning against Orochimaru, the No. [-] Kage in Hokage.

But at least it can be evenly divided.

This is why Kayn dared to come to Orochimaru.

Orochimaru calmed down a bit.

Although his face was gloomy, he still said calmly: "Suoga, it turns out that excellent genes can always be passed down through competition!"

"So, what do I need to do if I join the organization?"

"No need to do anything! Just do your own thing well, and keep getting stronger. By the way, help me do some experiments."

"Ho ho ho, I agree to join!"

"Well, connect it." After speaking, Kayn threw a test tube to Orochimaru, which contained a dark red magic crystal.

"The preparations are quite complete. Are you so sure that I will join? Mr. Kaiyin?" Orochimaru looked at the test tube thrown by Kayn, a little surprised.

"You will, because you can't refuse at all!" Kayn looked at Orochimaru with an inexplicable smile on his face.

"Ho ho ho, I'm really getting more and more interested!"

"The way to use this thing is to swallow it directly. After that, you can study it slowly. There are still some things that I will tell you later." Before he could finish speaking, Kayn's figure disappeared into the ground not see.

"Ho ho ho, it's really scary." Orochimaru also stared at the place where Kayn disappeared.

"Second brother, why do I only have arms that can use darkinization?"

Sasuke stared at the changed right arm, and looked suspiciously at Kayn who was practicing on the lake.

"Huh—" finally stood on the lake smoothly.

"You were a pure human being before you became a darkborn, and it takes time to become a pure darkborn."

"The magic will slowly transform your body, you just have to wait."

"But until you choose your Sigil weapon, only the right arm can be Darkinized."

"Once the imprinted weapon is selected, it cannot be changed, so you must grasp it carefully. All you have to do now is practice and wait."

"Summer." Sasuke suddenly realized.

After magical transformation, Sasuke who became a dark descendant is naturally different from the original.

The current Sasuke is extremely talented, definitely no worse than Itachi, and after two years of sharingan, he has reached Sangouyu.

"Tat-tat-tat-"

Kayn returned to the ground, eyes closed.

He opened it suddenly, and there were already Sangouyu in his eyes.

After two years, the first phase of the experiment was finally completed.

Let mana replace chakra.

But this was not what Kayn wanted.

Each world will have a different power system.

It would be too troublesome if magic power had to be replaced by experiments every time he crossed a world.

Moreover, the two cultivation systems cannot be cultivated at the same time, which leads to Kayn's current strength being very strong.

But as far as the chakra system is concerned, Kayn now doesn't have any ninjutsu except for the initial fireball technique.

The amount of chakra has also been staying at the bottom of the forbearance, or even worse.

It's not that Kayn doesn't want to practice chakra, there are many ninjutsu that are even easier to use than magic!

But if you practice the chakra system, the magic power system will fall.

Traveling to other worlds will only protect the magic power system. If the magic power cultivation fails, traveling to other worlds will lose the power guarantee!
If you only practice the magic power system, chakra will fall.

Obviously only the ninja with the amount of chakra can beat Otsutsuki Kaguya!

No one will believe this!
Fortunately, this is Hokage, people here don't really pursue this, and most of them will regard it as the boundary of blood inheritance.

But what if the next world is the world of cultivating immortals?
There are as many saints as dogs, and the emperor walks all over the place.

If those people find out that their cultivation system is different, they will definitely be regarded as heretics, members of the Demon Cult!

Therefore, not only dual cultivation is required, but also the magic power must be mixed with the original world power system, that is, fusion.

For example, two engines, one with oil and one with diesel, combine the two fuels so that both engines can be used!
Not only can you increase the level of magic power, but you can also use ninjutsu.

After all, Kayn has been coveting ninjutsu for a long time, such as sharingan, such as various blood inheritance boundaries.

Some time ago, when Sharingan still needed to use chakra, it would not work just after opening it for a second.

Now that magic power can finally be used, Sangouyu can even remain normal.

"Hey, the next stage is the second stage of the experiment, fusion." Kayn looked up at the sky and thought silently.

It would be better to say it is swallowing, after all, magic power is higher than chakra.

How to let the magic power devour chakra, how to let the Sharingan blend into the soul.

Well, it's time to hand over these to Orochimaru, after all, experimenting is not my specialty.

In a dark laboratory.

Bottles and jars filled with various glasses.Only the sound of ping-pong-pong glass crashing echoed.

Orochimaru, who was doing experiments, suddenly stopped, and picked up a stack of experimental data next to him, where various bottles and jars were filled with mutated mice.

And a tightly tied person, half of his body has mutated, but his eyes are empty, like a machine that can only execute instructions.

He looked at the dark red crystal soaked in an unknown liquid, and his eyes shone with an inexplicable light, "Sbarasi!" Orochimaru whispered to himself.

"Double." A hoarse voice sounded.

"What's the matter? Master Orochimaru." The figure beside him bowed respectfully, his expression full of respect.

"It's the last step, you go out, no matter what happens, don't disturb me!" The hoarse voice could no longer hide the excitement in it.

"Hi!" Dou slowly exited the laboratory, closing the door behind him.

There was no movement around the laboratory.

Orochimaru took out the dark red crystal from the test tube and put it in the palm of his hand.

Staring at the crystal as if looking at a treasure, "You really gave me a shock, Mr. Kayin!"

"Darkborn? It sounds very good too, ho ho ho ho." He said and swallowed the crystal.

The whole body gradually began to itch, from itching to pain, tearing pain.

It made Orochimaru extremely uncomfortable. Although the anesthetic had been administered in advance, the pain of the genetic modification still tormented Orochimaru.

"Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" the severe pain made Orochimaru growl in a low voice.

The severe pain made Orochimaru feel the elongation of time more and more.

The duration of the first phase is one hour.

This is also the result of Dashewan's experiment.

"Ha-ha-ha-" Finally, after the last second, the pain gradually disappeared.

Then he clenched his teeth again, ready for the second stage.

"Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" came out again.

It was the pain from the soul being torn apart.

The severe pain made Orochimaru almost stop thinking.

I don't know how long it took, and finally felt groggy, and finally fell into a coma.

"Ha—" There was a violent inhalation sound in the originally silent laboratory.

Orochimaru sat up abruptly, taking a big breath of fresh air, his light yellow vertical pupils were full of panic.

Recalling that piece of dark space just now.

Orochimaru swears, claiming to be the number one dog in Hokage, with the pinnacle of life-saving ability, even if his body dies, he can be reborn with the curse seal, and he has never been so close to death.

That is the fear from the soul.

The cold sweat has soaked through the clothes, and he is still panting, as if he has not recovered.

"call-"

It feels so good to be alive!Orochimaru thinks so!
He raised his right hand and looked at the back of his hand.

Inky black imprint, an intricate pattern of eyes in a hollow circle.

The extra knowledge already in his mind is about dark descendants and magic.

Browsing through this knowledge, I lost my mind for a while.

"Sbarasi!" Orochimaru, who was full of thirst for knowledge, exclaimed, "This is really a great gift! Kayn-kun! Hohohohoho"
