What exactly is the curse mark that he made, Orochimaru couldn't be clearer.

On the surface, it is the product of studying Shigego's body, but in fact, it is an accidental result of his own research on the immortal mode of Longdi Cave, so using the spell mark can get a spell seal similar to the immortal pattern. Of course, this "spell sealing" is undoubtedly very different from the real immortal mode.

"I see, did you sublimate the curse mark I gave you to the original and return to the original into immortal arts? Or is it a new Immortal mode? Orochimaru looked at Li Shuimu with interest, "Hehehe, what an admirable talent!" However, are you sure that the 'Immortal Mode' you created has no side effects? ”

Hearing this, Li Shuimu's face changed slightly.

It seems that his guess is not wrong, since he can also practice frog immortal art, how can the more talented and stronger big snake pill not be able to practice snake immortal art?

It's just that he himself senses that there is something wrong with natural energy and disdains to practice.

Li Shuimu looked at him quietly, but put away the "Immortal Mode" instead.

"Orochimaru-kun seems to know a lot." Li Shuimu said softly, "Did you get it from studying the forbidden technique?" ”

"Hehe, most people in the world think that studying forbidden arts or so-called taboos is evil, even heinous." Orochimaru laughed, his eyes revealing a hint of madness, "But how do they know, it's just mediocrity!" Do they understand the origin of ninjutsu? Do they understand the development of ninjas? Do they know the future of the ninja world? Hahaha, how can those mediocre people know about these things?! But I know! I learned about the origin of ninjutsu from studying forbidden arts, and I learned about the history and development of ninjas from exploring taboos...... As for the future of the ninja world, this is my next topic, and when I get those two writing wheels......"

"......" Li Shuimu looked at him quietly, with a trace of pity hidden in his eyes.

In Li Shuimu's view, Orochimaru is undoubtedly the wrong child. If he had been born in a world of technology, he would have been a great scientist. It's a pity that he was born in the ninja world, a world where everyone attaches more importance to practicality and doesn't care about theory, and his scientific research spirit can only satisfy his own research desires, but it is not accepted by the public. Therefore, he can only go further and further along the road of "evil" in the strange eyes of the world.

In the beginning, Orochimaru's research was only aimed at immortality, but as his research deepened, he explored the truth in the history of the ninja world and found out the origin of ninjutsu and the blood inheritance limit.

If it is said that the strongest person in the ninja world now must be Nagato, who can drive the eye of reincarnation at will, and the power that touches the origin of the world is an immortal; However, if you talk about the understanding of the essence of chakra, and the cognition of various blood inheritance limits, no one can come out of the Great Snake Pill.

But the more you understand, the more troubles you have. "Everyone is drunk and I am sober" is not pleasant.

Orochimaru's research made him understand that there was a limit to the growth of ordinary people's strength, and he had basically reached that limit now. Only a few special bloodlines can break through that "ceiling" and see the scenery of a higher level.

So, he adopted Kaguya-kun Maro, and coveted Sasuke Uchiha, and then thought about the Yamato that could be used as a result of his research on the first generation of cells...... Obviously, he understood the special nature of these bloodlines.

However, looking at its current appearance, it doesn't seem to be particularly sober. I'm afraid that Li Shuimu's other guess is also right: Orochimaru did practice the snake immortal technique before, which is why he was able to absorb the "owned" chakra from the dou who used the 'immortal mode'; But he sensed that something was wrong, so he abandoned the snake immortal technique, and in order to ensure his purity, he did not hesitate to decompose a part of his soul, which is why his mental state was ridiculously poor - that was not the result of using two immortal reincarnations!

"Is it worth it to touch taboos and kill innocents for the sake of research?" Li Shuimu suddenly asked.

"Innocent? Who in this world is really innocent, do you have a standard for judging? Orochimaru's tone became indifferent, "What's more, for the advancement of ninjutsu, a certain sacrifice is essential!" Do you know how the second generation of ninjutsu, who created a large number of ninjutsu back then, created his ninjutsu and even forbidden arts? ”

"......" Li Shuimu was speechless for a while, and the iron-blooded second-generation Hokage was in a thousand hands, that was a ruthless person who could put his sister-in-law's first nine-tailed man under house arrest for a lifetime. He has created so many ninjutsu by himself, especially forbidden techniques such as reincarnation of the dirt and the seal of the ghouls, it is strange to say that there has been no human experiment.

"What was the purpose of the spell seal you gave me in the first place?" Li Shuimu suddenly asked, this is a question that the original "Shuimu" has never figured out in his heart.

"It's just a matter of doing it," Orochimaru said casually, and as he spoke, he glanced deeply at Li Shuimu, "I was impressed by how neatly you killed your injured teammates, so I gave you a spell mark." It's just that what I didn't expect was that you would be able to transcend the realm of spell marks and sublimate immortal arts! This is something I didn't expect. ”

"Thank you for helping me." Li Shuimu bowed slightly.

"Mizuki-kun, although I don't know the immortal mode now, my research on immortal arts is not shallow," Orochimaru said with a wicked smile, "You might as well follow me in the future, I will give you a lot of information you use as a reward." ”

Li Shuimu felt that Orochimaru's eyes looking at him were as if he was looking at a precious test item, which made him feel very bad.

"Orochimaru-kun, knowing that you are very powerful, you don't need to show off any more!" Li Shuimu waved his hand, "In a word, fight against me, win me, I'll go with you, you can study as much as you want!" ”

"You said it yourself!" Orochimaru smiled, and suddenly came forward, "Snake Shadow Sneaker!" ”

With a flick of the sleeve of the big snake pill, a large number of poisonous snakes rushed out and attacked Li Shuimu.

"It seems that Orochimaru-kun looks up to me very much," Li Shuimu dodged the attack of the poisonous snake lightly, "It's a famous stunt as soon as it comes up!" By the way, I have one more sentence, if you lose, I will collect the loot! ”

"Hehehe, it's up to you!" Orochimaru sneered evilly, "Multiple snake shadow sneakers! ”

The size and number of the poisonous snakes that attacked this time have undoubtedly increased several times, and the attack speed has also doubled!

"Tsk, it's really worthy of the name of snakes, it's all snakes!" Although the poisonous snake is powerful, he still can't hurt Li Shuimu, but he is always annoyed by the poisonous snake. After all, even people who are not afraid of snakes always have resistance in the face of that slippery and greasy thing.

"Secret Technique: Tiger Potential!" With a glaring of his eyes, a momentum of the king of beasts emanated, and suddenly all the poisonous snakes retreated, no matter how much the Great Snake Pill urged, it didn't work!

"Mystic Psychic Beast Retreat!" All around was empty, and all the poisonous snakes turned into white smoke and dissipated.

"Sure enough, although these poisonous snakes are not summoned by spiritism, they are all psychic beasts originating from the Dragon Earth Cave." Li Shuimu nodded clearly, but on the other side was Orochimaru's ugly face.

"Looks like it's going to be a tough battle!" Orochimaru couldn't help but sigh.
