Locking the target on 'Ten-Tails' is the same idea in the minds of Yayoi and Nene.
They have read various records in ancient documents. Although at least more than a thousand years have passed since that era, and much of the history has been covered up, there are still fragments of information that have been passed down to this day in various forms.
It's just that except for relevant historical scholars, ninjas are not very enthusiastic about the exploration of ancient history.
Sage of Six Paths, Tailed Beasts, and Ten-Tails, the collective of Tailed Beastss, all tell the story of a dangerous war that once took place on this land that affected the entire world.
That war ended with the final victory of Sage of Six Paths, but what happened after that?
It seems that the immortal has not properly resolved some issues left over from history, and they continue to this day.
Yayoi can clearly feel the oppressive feeling of an approaching storm.
Decades later, there will be an organization called "Akatsuki", which, under the guidance of a guy who calls himself "Madara", will continue to collect Tailed Beasts in an attempt to make the so-called Ten-Tails reappear on the land of Ninja World and build a dream world of unity that sounds ridiculous.
According to the ideas given by Nene and his guesses, if he wants to truly grow, he may need to use a large amount of Tailed-Beast Chakra, or even... Chakra that is close to the 'source' of Ten-Tails.
In this way, he must collect all Tailed Beasts, and then find a way to revive Ten-Tails.
Let's not talk about the difficulty of collecting Nine Heads Tailed Beasts and what steps are needed to revive Ten-Tails. The most important thing now is to improve one's own strength.
No matter how beautiful the plan is, it must have enough power to implement it, otherwise it will all be empty talk.
Yayoi and Nene both couldn't help but sigh, obviously they thought of being together again.
Nene was even more anxious, wishing that Yayoi would immediately turn into 'Ten-Tails', and then let her study it hard.
But improving strength, no matter how urgent it is, cannot be solved in a short time.
"We need to develop some life-extending medicine."
Nene's murmur was heard by Yayoi.
"Life-extending medicine?"
Yayoi was surprised that Nene turned his attention to this aspect.
Nene rolled his eyes at him.
"Of course, the hypothesis, execution, and organization of experiments take a lot of time. Especially this kind of experiment that seems at first glance to take decades or even hundreds of years, and may not be successfully completed. If you don't extend your life span, how will you survive until the day the experiment is completed?"
With Land of Night's current strength, just catching all Tailed Beasts would be a jam.
"..."
It is reasonable and well-founded, and Yayoi is very convinced.
This makes Yayoi think of a guy who spits out a snake from his mouth and then spits out a sword. He has unimaginable persistence in extending his life.
"Speaking of which, your appearance is probably caused by taking some kind of medicine."
Yayoi looked at Nene's whole body. She was clearly in her twenties, but her body was still that of a delicate girl of fifteen or sixteen.
"It's just a semi-finished medicine. It can only make your appearance and body younger, but it will not extend your life. You will still die when the time comes. Moreover, the medicinal materials are difficult to find, and the refining process is also very troublesome. Mass production is currently not possible."
Nene nodded.
Although she usually looks stoic, she is still a woman after all. She cares about her body and appearance and doesn't like the feeling of aging.
"Can the life-extending medicine do that?"
Yayoi is also a little excited. Whether it is to maintain youth or extend life, it always has an inexplicable and powerful attraction to human beings.
"It was hard to tell before, but now that I have your Chakra, maybe I can even make 'Elixir of Immortality'..."
Nene once again focused his attention on Yayoi's body. His gaze was no longer as hot as before, but he still couldn't help but stretch his tongue out of his small mouth and lick it. His mouth was dry and he seemed a little impatient.
In response, Yayoi nodded and agreed happily.
If his body is used for research, he will probably hesitate, but if it is just Chakra, he can still provide it continuously.
He is also looking forward to what kind of medicine Nene can use his Chakra to make.
◎
After discussing with Nene, Yayoi became more focused on Yin-Yang Release's cultivation, and even other aspects of cultivation were temporarily postponed.
If he can fully master this technique, it will help him further understand and penetrate Chakra. In this way, not only can he complete the imperfections in the bodies of Irori and Yaya, but it may also be able to affect his own body and transform into the form of Tailed Beasts.
However, due to lack of experience and the fact that Yin-Yang Release has not yet mastered it perfectly, Yayoi does not dare to experiment directly with his own body.
After all, the flesh and blood of the human body is too fragile. Before a large amount of reliable research data is obtained, using Yin-Yang Release to modify one's own body is a taboo field that is too scary and dangerous.
At the same time, Yayoi did not forget another important thing.
An important work that had been temporarily suspended by him may now be restarted.
"Relic exploration?"
In Tenshu Tower, Hokuto, as the patriarch of Land of Night Uchiha Clan, stood one or two meters in front of Yayoi's desk. When he heard what Yayoi explained, the corner of his mouth suddenly twitched.
It seems to remind me of the various archaeological missions I received from Yayoi before I joined Land of Night.
Although the rewards are generous, the process is extremely boring and arduous. They often go deep into some desolate polar regions, and sometimes they have to dig holes with Earth Release Technique constantly to unearth ancient ruins that collapsed deep underground due to earthquakes.
Izayoi, who was sitting not far away and was processing paperwork, moved his ears and heard the conversation between Yayoi and Hokuto. A mask of pain subconsciously appeared on his face, probably because he was thinking of a certain unpleasant memory in the past.
Fortunately, she no longer needs to do this kind of work.
Her daily job now is to handle paperwork here and serve as Yayoi's sparring partner. She occasionally goes out on dates with Yayoi, and their relationship continues to heat up as they get along day and night.
"Yes, do you have any questions?"
"No, there isn't."
Hokuto shook his head.
Although the work was a bit troublesome, he knew that this kind of work was not difficult for a ninja of his level, but it would just take longer.
However, he has sufficient archaeological experience and can save a lot of time.
"This is the list of members of the team. Take a look."
Yayoi handed over several lists, and Hokuto took them and quickly read them.
This archaeological team searching for ruins has him as the captain, and there are four other members.
A Jonin who is Aburame Clan, a Jonin who is proficient in Earth Release Technique, a Chunin who is proficient in the Hyuga Clan, and a Chunin who is proficient in Medical Ninjutsu.
The team configuration is very complete, including Medical Ninja, and is suitable for exploration and collection work in various complex environments.
There are three Jonin among them, and they are also capable of infiltrating into some dangerous areas.
After all, there are many uncontrollable dangers in some ruins. In addition, due to their age, the buildings are prone to collapse. Without certain strength, they may be buried inside.
"The team is very complete."
Hokuto put down the list and nodded with satisfaction.
This five-person team integrates combat, search, and Medical, as well as Earth Release ninjas who can change the terrain. Even if they are unlucky enough to encounter a collapse of the ruins, they will not be in danger.
"If there is no objection, execution will begin tomorrow. This is the place to be searched."
Yayoi handed over some maps.
"Yes."
Hokuto took these maps and took the order to go down. He planned to find all the people first, then make some preparations, and set off early tomorrow morning.
After Hokuto left, Yayoi had nothing to do, so he picked up some unfinished ancient documents and continued to look through them, hoping to find important information that would be useful to him.
For example, Ten-Tails, Sage of Six Paths and other legends based on reality.
Letting Hokuto and others search the ruins was naturally based on this idea.
Only by knowing your enemy and yourself can you fight without danger.
And maybe in this kind of search for ruins, some unexpected good things can be brought, such as some ancient lost technologies and Ninjutsu, which are also of great reference significance to him.
Because Yayoi discovered that the more ancient the technique, the more primitive the use of Chakra is. It is not as complicated and changeable as it is now, and there are so many types.
But this 'original' Chakra utilization is exactly what Yayoi wants to collect.
After reading for a while, Yayoi left Tenshu Tower and walked towards the underground space layer below General's Residence.
Next is the time to study and practice Yin-Yang Release. Regarding the use of Yin-Yang Release, Yayoi has already entered the practice stage, but this practice is not complete. In use, it can never achieve the results that satisfy Yayoi.
At least he can't make Irori and Yaya complete the ultimate life transformation of Chakra and become the same life form as Tailed Beasts.
Therefore, he needs a good reference target that can not only allow him to exercise Yin-Yang Release, but also allow him to conduct Yin-Yang Release's 'human body transformation' experiment and collect necessary experimental data.
"This should be considered a 'living body'..."
The figure of Yayoi is reflected on the transparent hemispherical glass. Through the smooth and clear glass, you can see the giant brain soaked in Solution.
The brain is two stories high, with an amazing artistic sense of wrinkles, and the surface is full of hooks of different shades. However, this brain's entire body is made of Chakra Metal, making it a veritable steel brain.
It was Unit Zero Puppet that he created a long time ago. The body is a special puppet creation made of pure metal.
It is also the information and processing center that controls the puppet army. It can connect and react with his Chakra. It is the veritable "brain" of this underground space.
Although it has no intelligence or the ability to organize language, it undoubtedly has the concept of "life", has the ability to remember and distinguish between ourselves and the enemy, and will completely execute orders according to the will of Yayoi.
Yayoi plans to use No. 0 as his first Yin-Yang Release experimental subject, remodel and upgrade its structure, and try to make it produce intelligence equivalent to human beings.
"Take your time..."
Yayoi took a deep breath, first emptied the Solution in the glass cover, then opened the entrance and stepped inside.
Then, Yayoi stretched out his hands and pressed them on the cold metal with residual water stains. An invisible wave spread around him, with Chakra containing the power of yin and yang slowly seeping inside.
