Chapter 152: Orochimaru's Research

Konoha, the underground laboratory that once belonged to Root, has now been put back into use.

And today, this former laboratory has welcomed a familiar visitor once again.

Walking through the dark and damp corridor, a hint of nostalgia appeared in Uchiha Feiyu's eyes; back when he was in Root, he had often walked through here.

The ninja of Root were basically lifeless and rarely spoke; at that time, he and Danzō were still in a cooperative relationship, and most Root ninja still had no reaction after seeing him.

Now, there are a few more ninja here, many of whom look somewhat strange; they should belong to Orochimaru's subordinates.

After all, aside from Orochimaru's human experiments, Konoha really couldn't find many ninja strange enough to have grown six arms or two heads.

These ninja are highly vigilant; compared to Root ninja, although they lack professionalism and do not have that cold, murderous quality of dead soldiers, they are all full of energy, clearly fanatics lured here by Orochimaru.

But this vigilance was clearly useless against Uchiha Feiyu; under the control of his five-sense Genjutsu, Uchiha Feiyu walked as if there were no one there, all the way to the innermost laboratory.

The door to the laboratory was pushed open; compared to the cold and damp corridor outside, which had no decoration and was dug out directly using Earth Release, the interior of the laboratory was bright.

"Long time no see, Feiyu... Every time we meet, you always manage to come up with something that surprises me."

Therefore, Uchiha Feiyu has gradually stopped caring about Blood Qi Pills, because this thing is indeed useless to him; by comparison, pure chakra power and Soul power are at least something Uchiha Feiyu has not yet seen the limit of.

"Hehe, where did you get those materials? They are completely outside the chakra system... Forget it, if you don't want to say it, then don't."

"There is even more... for example, the Universal Chakra Plan; this is a much bigger move than the 'one country, one village' system!"

Moreover, Blood Qi Pills can only achieve this much; the physical fitness increased by this kind of pill also has a limit, or to be precise: the flesh-and-blood life of the Naruto World has a limit.

"That is true..."

Orochimaru, who also once obtained the Hunyuan Treasure Box from Uchiha Feiyu, is perhaps the only "outsider" in the entire Naruto World who guessed Uchiha Feiyu's thoughts; the so-called Universal Chakra Plan, in Orochimaru's eyes, is undoubtedly selecting higher-quality sacrifices for the Hunyuan Treasure Box.

Especially now that Orochimaru has practiced the improved version of the Living Corpse Reincarnation, his mental power and Yin Release chakra have increased significantly; by supplementing the Yang Release chakra that his physical body lacked, he vaguely has the feeling of being about to awaken Yin-Yang Release.

"Many, many things... for example, your ambition; controlling the Land of Wind and the Sand Ninja is not enough, and now Konoha and the Land of Fire are already under your control, aren't they..."

"What are you referring to? Teacher Orochimaru? Sorry, there are simply too many things I can make you surprised by, so I don't know what you are referring to."

When the Ninja World evolves to the highest degree, the physical body with the strongest Qi and Blood is at the level of Senju Hashirama; as for the Otsutsuki Clan, they have already evolved into chakra energy organisms and do not belong to flesh-and-blood life at all.

"Another thing that has yielded results is the Thousand Spider Ten Thousand Poison Hand, this rather strange ninjutsu... no, to be precise, this has already exceeded the scope of ninjutsu and is closer to a Bloodline Limit of the release type."

Borrowing the Blood Qi Pills made with the Hunyuan Treasure Box, Orochimaru's current physical fitness and chakra volume are almost comparable to a Tailed Beast.

"By the way, Teacher Orochimaru, do you have any new inventions recently? How much of the data I gave you have you analyzed?"

"The more people who possess chakra, the more you can obtain, right!"

Orochimaru in the laboratory turned his head to look toward the entrance, a cold smile on his lips as he spoke.

Orochimaru chuckled and skipped over this topic; compared to Uchiha Feiyu, Orochimaru, who has perfected the Living Corpse Reincarnation and may need to change many bodies, has a much greater demand for Blood Qi Pills.

"That so-called Heavenly Demon Dissolution Method has already been improved by me; as long as you change the flow of chakra and break through a few chakra nodes, you can make your chakra skyrocket dozens of times and last for five to ten minutes."

Of course, this is just a feeling; without a pure Otsutsuki bloodline, relying solely on Yin Release chakra and Yang Release chakra to force it, even Uchiha Feiyu does not know what amount of chakra is needed to synthesize Yin-Yang Release—anyway, Orochimaru's current chakra volume is definitely far from enough.

"However, as long as it is used, the best result is the rupture of chakra channels and never being able to be a ninja again; the vast majority are almost certainly on a path to death, which can be considered a version of the Eight Inner Gates Formation with greatly reduced power and a shortcut."

Of course, Uchiha Feiyu has gone much further in the aspect of "cannibalistic Immortal Cultivation" than Orochimaru thinks, and what he eats is much more refined than Orochimaru imagines; this point is not known to Orochimaru.

"Alright, Teacher Orochimaru, after the Universal Chakra policy is implemented, I am not the only one who will profit from it; even if I am the one eating the meat, haven't you had some soup, Teacher Orochimaru?"

"Chakra that has absorbed a large amount of toxins can be directly called Poison Release; it can not only poison the opponent during close-quarters combat, but can also be mixed into Wind Release and Water Release in the form of poisonous gas and venom."

"As for the aftereffect of disfigurement and physical damage, it is actually because the body cannot withstand the toxicity in the chakra; as long as you do a little physical modification, it will be fine."

"After all, the toxin has become very mild after being transformed by chakra, and the cultivation method of this ninjutsu itself will also strengthen the user's poison resistance, so this kind of modification is not very difficult."

While speaking, Orochimaru stretched out a hand, and his palm instantly turned pitch black, gently brushing against a ninja tied to the experimental table.

That ninja's face turned purple-black in an instant, his whole body trembling; in just a few seconds, black blood was already flowing from his seven orifices, and he was about to lose his breath.

"Such powerful toxicity, you must have improved the Thousand Spider Ten Thousand Poison Hand again!"

Uchiha Feiyu walked over to take a look and said with some amazement; one must know that Orochimaru had only lightly touched the ninja's skin with his palm just now.

With such a small contact area and such a short contact time, the ninja was already dying after just one touch; this effect is much stronger than the original Thousand Spider Ten Thousand Poison Hand.

"I changed the original spider venom to snake venom; the large snakes of Ryuchi Cave have been cultivated by me, and their toxicity is strange and varied, much more complex than the toxicity of ordinary poisonous spiders."

As Orochimaru spoke, he grabbed the poisoned ninja, took out the Hunyuan Treasure Box from his bosom, and directly put the ninja inside—as long as the ninja is alive, they can be used to refine pills; he is not wasting anything now.

"In fact... it doesn't matter whether it is spider venom, snake venom, or scorpion venom; the essence of this ninjutsu is the method of using deadly poison to transform chakra and make it mutate. As long as you find this method, it doesn't matter what kind of toxin is used."

"At most, different toxicities will have different effects on the body, and the resistance produced by the cultivation method of the Thousand Spider Ten Thousand Poison Hand is only most effective against spider venom."

"Through the improvement of this ninjutsu, my body has now also developed resistance to snake venom and can fully accommodate this chakra filled with snake venom."

Uchiha Feiyu curled his lips, flipped through the ninjutsu scroll handed over by Orochimaru twice, and then returned it to Orochimaru.

Things like poison techniques are mostly products of seeking quick success and instant benefits; they can produce lethality in a very short time, but their upper limit is basically not high.

After all, the effect of poison techniques is often 'killing 1,000 enemies while suffering 800 losses'; no matter how much you improve your resistance, it is difficult to avoid damage to your foundation and Origin. Often, it only increases your Power Level, but instead damages your life's Origin.

Uchiha Feiyu himself would not practice it, and it is impossible to spread this kind of poison technique on a large scale—this kind of poison technique that damages the life's Origin is not a good way to cultivate leeks; at most, it is used to train a few thugs.

'But I am almost controlling the entire Ninja World; having thugs or whatever doesn't seem to be of any use!'

The things Orochimaru researched cannot be said to be useless; if it were still in the era of ninja villages, whether it was the Heavenly Demon Dissolution Method or the Thousand Spider Ten Thousand Poison Hand, they could be converted into the combat power of the ninja village in a short time and increase the foundation of the ninja village. But for the current Uchiha Feiyu, it cannot be said to be completely useless, but it is just of no damn use.

But Uchiha Feiyu thought about it, the messy things he gave to Orochimaru didn't seem to be able to research anything good either...

"Alright, these two research projects can be thrown into Konoha's Scroll of Seals; I will get some real secret treasures for you to research later."

Uchiha Feiyu waved his hand, interrupting Orochimaru's ongoing, incessant introduction. Upon hearing this, Orochimaru licked his tongue, saying that his mouth was a bit dry from saying so much, and then he stretched out a hand.

"What is this for?"

Uchiha Feiyu tilted his head, and Orochimaru retorted irritably:

"To give money, to give funding?! You think these things are researched for free! These were all exchanged with real gold and silver!"

"Tsk, so you came to ask for money!"

Uchiha Feiyu gave a light 'tsk'; no wonder his cheap teacher talked at such length—it turned out he was short on funding!

Of course, Uchiha Feiyu also knew that Orochimaru must have swallowed a lot of funding to conduct his own research; counting on him to honestly do research and work for himself is better than counting on poisonous snakes to stop eating meat and switch to a vegetarian diet in the future.

"Fine, I can approve the funding you want, but when the time comes, I will have Tsunade look over the specific research projects, experimental materials, and experimental consumption."

Nowadays, Uchiha Feiyu effectively controls three major nations, so he certainly isn't lacking in money, but he also doesn't want to be a sucker; with Tsunade watching, at least Orochimaru's misappropriation of funds won't be too outrageous.

Orochimaru's expression stiffened slightly; as a master of Medical Ninjutsu, Tsunade had naturally conducted many Human Experiments herself and knew the consumption of various experiments in great detail, so it probably wouldn't be easy for him to fool her easily, and it seemed he would have to put more effort into preparing the financial reports.

However, the most important thing is actually not research funding; for Orochimaru, what he wants most are Soul Pills, as well as the endless stream of strange knowledge in Uchiha Feiyu's hands.

It's just that neither of these two things is easy to obtain; Uchiha Feiyu has use for the Soul Pills himself, and as for the knowledge in the Book of Demonic Inheritance, most of the useless parts have already been given to Orochimaru, while the rest are Uchiha Feiyu's trump cards.

Because of this, what Uchiha Feiyu gives Orochimaru to research are only things of little value; although as knowledge from other systems, Orochimaru can gain quite a few benefits even just by drawing inferences from them.

But in reality, these things at most serve as a foundation of knowledge or enrich Orochimaru's methods, yet they cannot provide him with a fundamental improvement.

Not to mention that for Orochimaru, who has been determined to learn all ninjutsu since he was young, the unfamiliar knowledge system in Uchiha Feiyu's hands has a shockingly huge temptation for him!

Thinking of this, Orochimaru licked the corner of his mouth again and glanced at his cheap apprentice; whether for funding, for Soul Pills, or for more knowledge, perhaps he should find a way to bribe this cheap apprentice of his?

Although this guy is selfish, sinister, and cunning, possessing the same personality as himself, he is a young man after all, and Orochimaru discovered that this apprentice of his is quite similar to his former teacher and a certain white-haired companion—they are all quite lecherous!

But compared to his two teacher and companion who have the heart for lust but not the guts, this cheap apprentice of his is clearly a man of action who practices what he preaches, and his experiences are far more colorful and varied than those of Sarutobi Hiruzen and Jiraiya.

As mentioned before, apart from those of his own people controlled by Uchiha Feiyu, Orochimaru can be said to be the person in the entire Ninja World who understands Uchiha Feiyu the best; this understanding includes not only Uchiha Feiyu's personality but also his abilities.

Therefore, Orochimaru very easily discovered the changes in the Sand Ninja and the upper echelons of Konoha; the suddenly ascended beautiful female Ninja Village leaders and the young, beautiful, and powerful female ninja are clearly all part of the harem Uchiha Feiyu has created!

At first, Orochimaru only paid attention to this; compared to someone's lechery, he was more concerned with how his cheap apprentice could control these women without using any Genjutsu at all, and even significantly increase their strength.

But now, perhaps catering to his preferences is also a good method?

It just so happens that this time he found a vessel with fairly good aptitude, and most importantly, compared to the motley crew under his command, his vessel can definitely be described as beautiful in appearance and outstanding in aptitude.
