The lab was silent, and you could hear a needle drop on the floor.

Feeling the caressing of Orochimaru's neck, he suddenly stopped, Hinata Xunyi was stunned for a moment, and shouted angrily: "Do it!" Orochimaru, why don't you do it? Anyway, you've killed so many people, and you're not one of me, you demon who treats human life like a mustard! ”

“……”

"I'm curious, you seem to know a lot."

After a moment, Orochimaru's hand left the girl's neck, and at the same time, a hoarse voice came, seemingly with a hint of interest.

"How do you understand that I let those children be willingly tested by me?"

"Oh, the Ibri told me."

"The Ibris?"

Orochimaru tilted his head, as if thinking.

"That's right, the Ibri." The girl's words were full of sorrow, "When I found them, they drove them out...... This race trusts you so much and pins their hopes on you, but you take all their children and devote themselves to your evil experiments! ”

"Oh...... The Ibri. ”

Orochimaru's voice was sudden.

He finally remembered this race, and indeed he remembered such a race.

The Ibri clan, this is a magical race, they have the ability to turn their bodies into smoke, and can control the density of smoke, change shape at will, can invade and control the enemy's body, and can also use smoke to coerce others to fly into the sky, so that others can soar in the sky, just like "somersault clouds". Unfortunately, this ability is not stable, and the smoke that the body turns into is easy to blow away once it encounters a strong wind, and it can no longer be condensed and enter death. As a result, this race lives in tree hollows or underground all year round, and the average lifespan is only thirty years.

Orochimaru studied it for a while, and finally put something called "curse mark" on this race.

The spell mark stabilized their ability to smoke and extended their lifespan, but the spell was only a test and did not give them full control over the smoke power. However, due to the extended lifespan, the Ibri clan did thank him to Dade and was willing to provide him with experimental children.

Thinking about the reason, Orochimaru grinned and licked his lips.

"Little girl, you have to be clear, I never force anyone, I only trade with those who need it. I helped the Ibri, and they offered me experiments. Any questions? It's just a trade-you-will-you-will-your-own. ”

"Phew, you're taking the lives of their next generation, experimenting!"

Xun Yi spat out, a pair of pure white eyes, and stared at Orochimaru.

"You devil, don't use your demagogy as an excuse! You don't understand how fragile life is! You will only impose your own desires on others! ”

The empty laboratory, echoing with the girl's harsh scolding, was very harsh to hear.

Orochimaru looked at her without saying a word—oh, can't say yes, because he now has bandages around his eyes and can only look at it.

Gradually, a smile appeared on the corner of Orochimaru's mouth, turned his head, and said to the psychic snake on the side.

"I changed my mind and I need an experiment now...... Well, a container for some of my new research, and this girl is a good fit. ”

"What do you mean......" the psychic snake seemed to associate something.

"Use snake venom to keep her firmly under control."

Orochimaru stopped talking nonsense and gave instructions to the psychic snake.

"Yes."

The psychic snake nodded in agreement, and even urged the power of the snake's venom.

The next moment, the girl's whole body became stiff and unable to move, leaving only a pair of big eyes that were staring at her.

Orochimaru licked his lips, his excited look seemed to reveal the bandage, and he stepped over to the girl's side and put one hand around her soft body.

Xunyi felt bad, and there was a fear of the unknown, which was suddenly born from the bottom of his heart.

She wanted to struggle, but the onset of snake venom made her unable to move, and she could only be at the mercy of Orochimaru.

"Enjoy, the gift I brought you......" Orochimaru smiled, lowered his head, showed the long canine teeth on both sides, and bit down on the girl's delicate neck.

In an instant, a violent burning sensation, like a sharp jagged, gnawed at Xunyi's weak heart.

"Ah......h

Xunyi subconsciously screamed.

Immediately after, a red light suddenly appeared on her neck.

From the perspective of the psychic snake, you can see that there are some black tadpoles, starting from the teeth of Orochimaru, moving little by little in the direction of the girl's bite.

The Curse Mark of Heaven is a curse mark newly researched by Orochimaru.

Orochimaru has been thinking about it for a long time, why can some people use the immortal mode, but some people can't?

At the end of the day, it's because of the bloodline. Orochimaru once visited the White Snake Immortal, hoping that he would teach him the Immortal Mode, but he was refused, on the grounds that he had no bloodline, and as a civilian, his body could not withstand the power of the Immortal Mode, and he would collapse and die if he forcibly used it.

This result was unacceptable to Orochimaru.

Why do you have to have a bloodline to learn the Immortal Mode?

Could it be that in this world, bloodline is really everything? Only certain groups of people are entitled to certain treatments?

Impossible, this contradicts the philosophy of Orochimaru.

Orochimaru believes that anything can be solved by scientific means, and the same is true for the Immortal Model.

So he was looking for experimental materials, trying to find a way that could make civilians also tolerate the immortal mode, and "popularize" the immortal mode.

Later, he found a teenager named "Shigego".

This young man has the power of immortalization, and Orochimaru made a deal with him, drawing this power from him, constantly experimenting, and finally invented the "spell mark", which was applied to ordinary people, so that ordinary people could also become immortals. This is where the Ibri clan's spell mark comes from, but at that time, the spell mark was in an experimental state and needed some experiments, so their spell mark was not perfect.

But don't worry about it now, as the experiment progressed, Orochimaru finally developed the power of the spell seal.

Subsequently, he renamed the spell seal, calling it the "Curse Mark of Heaven".

The Curse of Heaven has not been found yet, and now there is a target sent to the door, how can it not be used well?

The spell lasted for about a dozen seconds.

Under the application of the Great Snake Pill Curse Seal, finally, Xunyi's neck was engraved with three black tadpole-like symbols, emitting a red light.

After the completion of the technique, the big snake snorted at the psychic snake.

The psychic snake understood and unraveled the snake venom.

"Plop!"

Xunyi's whole body went limp, collapsed to the ground, and fainted.

"Orochimaru-sama, is it really okay to hand over such a valuable experiment to this girl?" The psychic snake turned to Orochimaru and asked, "I can see that you wanted to kill her just now, but why did you change your mind later?" Doing so can be a bit of a problem. ”

"Of course I do."

A smile appeared at the corner of Orochimaru's mouth, and he said meaningfully.

"But, you have to know...... Everything I do, it's just trading, and this girl has the qualifications to trade with me. ”

"Uh, oh......"

The psychic snake blinked and nodded in confusion.

Well, although it has intelligence, the mind is still the mind of an animal after all, and it still cannot understand some complex human feelings.
