In Konoha, Naruto lies down

At a small stall under a tree, several people from Class 10 gathered together for a meal.

"Hey, what is that communicator project? Is it related to what Ino did?" Shikamaru took a bite of tempura and took a sip of wine.

"Yes." Naruto also sneaked in.

Shikamaru is married and has slowly grown a beard. He still looks a bit lazy, eating his food with his head down, bored, then slowly raises his head to glance at everyone.

"Having a communicator is indeed convenient, but the age of ninjas is slowly fading. I don't have much to aspire to anymore, and after getting married, I feel even more powerless."

Hearing the word "incapable", Naruto and Ino both looked up at Shikamaru, then suddenly turned to look at Choji.

Shikamaru was frightened by their gazes and immediately pushed them back with his chubby hand.

"Don't look at me! You are really..."

There was no such expression as "dirty" at that time, and Choji was disgusted by this pair of bastards. Shikamaru said something unintentionally, and the two of them stared at him.

What do you mean! What do you mean! Fatty eats your rice? Damn it!

"Ahem." Naruto grinned evilly. They were all adults and childhood friends, so it didn't matter to him.

Choji's face flushed red as he listened to Naruto's pointed cough and wanted to stand up and leave. But when he saw that there was still food on the table, he held back.

"The communicator is very troublesome. It will take at least half a year from the formal construction to the commissioning. This is only within the village. If we want to cover the Land of Fire, it will take about two years." Ino said.

The topic was shifted and everyone's focus was put back on the communicator.

"I heard that the Land of Lightning has covered part of the chakra communication and has also developed chakra weapons." Shikamaru said while drinking.

"Technological development is bound to have an impact on the status of ninjas, so those advisors are reluctant to accept emerging technologies."

"Whether you accept it or not, the technological age will eventually arrive." Naruto continued, "This is the trend of the times, and we are the transitional generation."

"If chakra weapons appear, won't ninjas become weaker in the future?" Choji asked with some concern. "Weapons can kill anyone in their hands."

"The era of ninjas will eventually end, and perhaps there will be no ninjas in the future," said Shikamaru.

He was not pessimistic, but made a prediction.

"The end is also the beginning. Weapons ultimately need people to use them." Ino presided over the communicator project, so she naturally felt more deeply.

"The power of ninjas is too strong, which is not good for the ninja world. If technology can check and balance it, it can usher in a new era." Naruto stroked the wine glass.

"What if a ninja who can fly and hide appears, and technology happens to develop to a certain level and enter the era of planetary battleships?" He became more and more excited as he spoke, and suddenly found that the dinner table was quiet.

Three pairs of eyes stared at him blankly, as if they were looking at a fool.

"Uh...I was just kidding."

........

The communicator project was launched, and Ino, the leader, was completely busy. Naruto didn't want to disturb her, so he simply turned his attention away.

Laboratory of the Medical Department.

Sakura tied her hair up, took off her protective suit, and washed her hands before leaving the lab. Seeing Naruto waiting there, she hurried over.

"How come you have time to come here?"

"I just got some free time, so I came to see you." Naruto stretched his head and looked left and right like a bumpkin. Seeing that Sakura didn't stop him, he wanted to reach out and touch the experimental subject.

"Hey, don't touch that."

"Oh oh." He quickly pulled his hand back.

Sakura laughed angrily and said, "Those are newly cultivated seeds. They took me half a month's hard work."

"Why did you suddenly grow your hair long?" Naruto glanced at her and suddenly asked, "You always had short hair when I saw you before, but you changed it after that time. I forgot to ask you."

"I forgot who told me that, but it seems like it's inconvenient to do research with long hair?"

"Yeah, but don't you just like long hair?" Sakura glanced at him and wanted to roll her eyes, "Why else would I have long hair?"

"Uh..." Naruto looked at the pink ponytail and was speechless. He really liked long hair.

If she has short hair, she has to be a simple and cute girl, but the ninja business is like a deep sea. The simple and cute ninja girl would have been killed long ago.

"Do you not like it?"

"I like it." He nodded.

Sakura stared at him with her clear eyes and suddenly smiled. Her eyes were like strands of silk threads, and a light glance made Naruto feel a little itchy.

He was very familiar with this look. He looked up at the sky, struggled a little, and nodded.

In an abandoned warehouse in the medical department, the two had an in-depth exchange of views on whether the Palm Immortal Technique could be popularized among the majority of medical ninjas.

Naruto used his solid practical experience, combined with theoretical data, to completely convince Sakura. Sakura blushed with shame and was helplessly defeated.

"When will you come next time?" Sakura looked up at him.

"This time I mainly want to ask you, is the top-secret information I took last time useful?" he asked.

"It's useful, but... we need to study it further." Sakura's cyan eyes flickered. "At least it's helpful. I'll tell you when I make some progress."

"Okay, don't lie to me, you should know the consequences." Naruto said it again, worried.

"I understand." Housewife Sakura turned her head and bit her lower lip lightly, probably recalling some unhappy memories.

This man was truly cruel, and every word he said was like a knife stabbing into her heart. Sakura didn't want to provoke him again. For her, everything was fine now.

She was happy at work, and Naruto would come to see her. She could also feel that someone really cared about her, even if it was just a second personality, he didn't want to disappear.

"By the way, look at this."

She pushed aside the pile of documents on the workbench and pulled out a thick book from the locked drawer at the bottom. It said:

[Speculative research report on the fusion of human blood with divine blood], [Theoretical and practical research on genetic fusion], [Fallen Angel Plan].

Chapter 366: All ninjas are mixed-bloods, those with pure blood are all crazy, only one or two are left

Naruto glanced at it and then looked away. He had written all of this. It was just a temporary guess and hadn't been put into practice yet.

The main reason is that he doesn't understand it, so he just wrote a bunch of nonsense. Anyway, the cover looks very serious, but it's actually a scam, and it's all white when you open it.

Sakura added some more detailed information, probably things that Balabala couldn't release. However, it was not as cruel as Orochimaru and was closer to medical research.

However, what is being studied is very special, it is the genes and blood of ninjas.

All power has a source, and the same is true for chakra. After the Otsutsuki's power was diluted by their descendants, the higher the concentration, the stronger the power.

"I call them half-bloods." Naruto spoke nonsense seriously, satisfying the evil taste in his heart.

"Hybrid?" Sakura was stunned. The lingering emotion on her face gradually faded. She held a piece of information and said, "Are you saying that the bloodline of ninjas is not pure?"

"Normal people can't refine chakra, right?" Naruto asked.

"Civilians really can't do anything..." Sakura's face looked a little strange, as if she saw an elephant through the eye of a needle, and her worldview was being weirdly distorted.

"But legends are not necessarily true. Maybe there are no immortals at all." She added in one breath.

"Gods do exist, at least in this world." Naruto muttered, just loud enough for Sakura to hear. "You can't call them gods, they're just another species."

"how do you know?"

"Remember the cave in Whirlpool Country?" Naruto suddenly brought it up, putting the blame on Whirlpool Country.

After all, the person is dead, can they still get up and send a lawyer's letter? He has a habit of distancing himself before saying something unorthodox.

Either it's Danzo's fault, or it's someone else's fault.

"Have you been in there?" she asked.

"Well, the murals inside record some legends." Naruto stopped talking halfway, walked to her, hugged her and sat down.

"Do you have a pen?"

"Yes, here it is."

He wrote and drew on the paper with one hand, while the other was restless, moving about. A hideous figure gradually took shape on the white paper, with horns on its head and no whites in its eyes.

"Isn't this... a white eye?" she asked in surprise, then paused, "Stop touching it."

"Ahem, the origin of the Chakra ancestors can be traced back thousands of years. Anyway... that's what's recorded on the murals. Everything has a traceable path, and it's probably very close to the hybrid's guess."

"You try it first, and we'll talk about it when there's progress," he said.

"How can I try without any information?" Sakura looked confused and sat in his arms. "Hey, let's get down to business. Don't...don't mess around."

"No, I'm just giving you some information." His hands were still writing and drawing on the paper.

Sakura wasn't sure what information he was giving her until she stared at his hand writing something on a piece of paper, then she breathed a sigh of relief.

She couldn't bear it again. She had something to do in the afternoon and couldn't continue to accompany him. She was transferred from the Hokage's office to the Medical Department Research Institute. She was really busy.

Ever since Naruto conquered her fortress from the outside, Sakura has become more serious. She still occasionally says some flirtatious words, but only when flirting.

"Legend has it that the first god gave birth to two great immortals with the blessing of humans. The old toad of Myōboku Mountain has confirmed that the two great immortals did exist."

This was something she had never encountered before, so she couldn't help but prick up her ears and listen carefully.

"and after?"

"The immortal is dead." Naruto tried to explain all these things as clearly as possible at once so as not to affect Sakura's future research ideas.

After all, you are helping yourself, so there is no need to tell half the story and hide the other half. Just focus on the key points.

"How can an immortal die?" She was stunned and blushed inadvertently, "Don't..."

"Because they are not immortals, they are almost human, but they call themselves immortals. Well... you can understand them as ninjas with extremely strong strength, which has exceeded the scope of human beings."

"God can't die?" Sakura discovered the blind spot.

"The murals record that they have a special means of immortality. They cannot normally die and are difficult to kill," Naruto replied, outlining a tree diagram on the paper.

At the very top was a portrait of a hideous person, with eyes bulging outward like onions.

There was a fork downwards, with a sage on each side. However, the Uchiha and Hyuga clans were right below the two sages, so there was no further fork.

"Gods don't die, but immortals do." Sakura stared at the two rows at the top of the tree diagram, biting her fingers unconsciously as she thought.

"Is it because of the birth? Given the blessing of humans, the child's bloodline is impure? So, it will grow old, get sick, and die like humans?"

"Well, that may be the case." Naruto was revealing the tip of the iceberg of the truth of this world to Sakura in advance so that she could be mentally prepared.

The Medical Department's research center focuses on humans, using medical ninjutsu to heal them. As Tsunade's direct disciple, Sakura herself possesses considerable medical talent.

Naruto couldn't trust Orochimaru, nor could he poach Shizune, so he could only place his hopes on Sakura. He needed Sakura, not just for her body.

To be more precise, he needed Hei Ying. Only Hei Ying would trust him without reservation, willingly be possessed, and do such a rebellious thing with him without telling anyone.

I initially avoided the black cherry blossoms as a nuisance, but luckily, I've since made a careful assessment. All I can say is that effort and reward are positively correlated. As for the pink cherry blossoms... we'll see when the time comes.

There must be a way. The worst case scenario is to share the body. However... Sakura's body seems to have been taken away by herself... Well, this.

I hope the main personality doesn’t recover so early, so I can sleep a little longer.

"Look, if you gather all the bloodline limits of all the ninja families together, it's more like a gathering of purer hybrids."

He spoke to himself, circling the Uchiha and Hyuga clans.

"The eye technique is slowly declining." Naruto pointed at the Hyuga clan. "The main family's talent is weaker than the branch family's, and their bloodline is unstable."

"The Uchiha clan's eye technique is powerful, which is also related to their xenophobia. They marry within the clan. Their bloodline is pure, but their mental state is not normal."

"Are you researching ninja families?" Sakura couldn't help laughing.

"By the way, if you study them, you can find some commonalities." He pinched Sakura and pointed at the two families in the picture and said, "Not only Konoha, I have also seen many ninjas from other ninja villages."

"It is obvious that the number of bloodline limits is decreasing, and the power of ninjas is gradually declining."

"why?"

"It's probably related to the dilution of bloodlines. Technology is developing. Assuming that the ninja world is at peace and no longer needs so many ninjas, many people have integrated into civilian life, marrying and having children with ordinary people."

"Get married and have children?" Sakura blinked and looked at Naruto. "If I have a child, and I don't have a Blood Limit, wouldn't that be equivalent to diluting your bloodline?"

"Uh..." Naruto didn't know what to say, "That kind of thing doesn't matter. The purer the bloodline, the less human it is. If the purity is too high, it's not human anymore."

"Oh." Sakura nodded, then laughed again, "So ninja bloodline is so interesting, it can indeed be studied."

"No matter what the research direction is, whether it's bloodline limits or hybrids," he said finally, "the ultimate goal is only one: to bring down the gods."

"Let gods get married and have children?" Sakura laughed. "Do gods really exist in this world? Where can we find them? I don't think they exist at all."

"That's not necessarily true," he said. "Those people aren't gods, they're just a little special. Getting married and having children is definitely useless; it would pollute their bloodline."
