Naruto: My version is ahead of the ninja world

In just three days, everything Yu-gen needed had been delivered... On one hand, Danzo was efficient and never dragged his feet; on the other hand, this level of support also proved that Danzo was full of expectations for this project.

"Yu Xian, the new reel is ready."

As the experimental assistant, Shinji Kohinata called out to Hazuru, who was counting experimental materials on the other side of the tent.

"Understood, Senior Zhenyan."

After taking inventory of the supplies, Yu Xian came to Zhen Yan's side and sat down at the table next to him.

After taking over the research work, at least the living conditions of Hazen and Kohinata Shingen improved. An independent laboratory was impossible, but they could have their own tent.

By the way, Akimichi Torifu, who had been staying in Konoha, finally returned to the front line, and Hagen returned the tent he had borrowed to him.

That's not the point. The point is that after Akimichi Torifu returned, he seemed to immediately have an argument with Shimura Danzo, and the antagonism between them seemed to be quite serious.

When Yugen met Akimichi Torifu, he subtly inquired why he had been staying in Konoha, knowing that Akimichi's fighting prowess was highly valued on the battlefield.

Akimichi Torifu's answer was vague. He only said that he assisted the Third Hokage in "reorganizing" certain departments of Konoha, making the village a unified entity during the war, and that the Hokage could command any department as easily as his own arm...

Yugen instantly realized that among the departments being reorganized, there was a high probability that Danzo's "Root" department was included. The Hokage's interference in "Root" affairs naturally provoked Danzo.

However, Danzo seemed to have no other choice but to sulk like a spoiled wife. "Root" was nominally the training department for Anbu ninjas, so of course it was under the Hokage's jurisdiction... Was there any place in Konoha that was not under the Hokage's jurisdiction? It can only be said that now is not the time for Danzo to create an independent kingdom within Konoha.

Yu Xian could only sigh inwardly that the current Third Hokage was indeed quite powerful, almost like a completely different person from the one who came later on.

Danzo Shimura, driven by impotence and rage, desperately needs cutting-edge scientific research to soothe his soul, so Hagen also needs to work hard.

Yugen sat at a table, unrolled a scroll, picked up a pen, and before putting pen to paper, subconsciously turned to Kohinata Shingen and asked:

"Senior Zhenyan, how many times is this now?"

"The thirty-third time, I guess."

"It's almost done. I have a feeling this time we'll succeed."

As he spoke, Yu Xian began to draw a complex sealing spell on the scroll... A circular blank area was left in the very center of the spell, surrounded by various characters and lines, which seemed rough but actually contained complex patterns.

Yu Xuan first infused the sealing formula with chakra, and then said:

"here we go."

He placed his palm down, directly in the center of the sealing technique, and then a Rasengan appeared out of thin air.

Next, Yu Xuan slowly pressed down with his palm. When the Rasengan touched the scroll, the scroll and the table below were not damaged. Just like a stone sinking into the water, the azure chakra ball slowly disappeared into the sealing technique.

After the Rasengan completely disappeared, the patterns of the sealing technique lit up briefly, then immediately went out.

"The scroll is fine, the sealing technique has been successfully activated... It seems to have succeeded." Yu Xian slowly moved his palm away, letting out a long breath.

"Yugen, when did you master sealing techniques? This kind of sealing technique that directly seals ninjutsu looks like some kind of advanced technology." Kohinata Shingen finally couldn't help but ask.

This technique doesn't seem like something a ninja of Yu Gen's background could master, nor is it possible for him to learn it by himself. He basically needs someone to teach him to learn it.

"I have a unique ability to comprehend these kinds of space-time ninjutsu; you could say I have a bit of talent... The process wasn't easy either; we tried for three days before we succeeded once, didn't we?"

Yu Gen didn't answer the question about the truth directly, but he didn't lie either... Thanks to the Fourth Hokage's help, Yu Gen's perception of space and time was indeed quite sharp, which was indeed helpful for him to master the Scroll Sealing Technique more quickly.

Space-time ninjutsu can be very sophisticated at times, and very practical and down-to-earth at others. For example, summoning techniques and scroll sealing techniques are space-time ninjutsu with a high degree of popularity.

"So, we've succeeded in the first step, right?"

"Yes, regarding sealing ninjutsu, what we need to do next is to practice continuously to improve the success rate. In addition, we need to try to create a device that can store chakra, also known as a 'chakra capacitor'."

"That sounds like a lot of difficulty."

"It's much simpler than I imagined. It's nothing more than a combination of metal that conducts chakra and various techniques for sealing, storing, and transferring chakra. Once you grasp the principles and keep trying, you'll soon succeed."

Developing this from scratch would indeed be no simple task. However, Yu Xian possessed the complete set of technical data and knew exactly how to overcome each technical challenge.

"Senior Zhenyan?"

Kohinata Shingen's expression was a little off. He sighed and said, "While other ninjas were bleeding on the battlefield, we were doing research in the camp. It always felt like we were in a different world from everyone else."

"It's just a different division of labor. If our research succeeds, it will definitely help Konoha achieve victory in the war more quickly."

"That's true."

Well, as long as it succeeds...

When Yu Xian was studying this scientific ninja tool, he always felt a sense of déjà vu. Later, he understood the source of this déjà vu—studying this thing was like assembling a vacuum tube radio.

During the principle verification phase, Yu Xian did not need to consider the requirements of actual combat, so he did not expect to shrink the ninja tool to the size of a wrist guard in one step. The "prototype" was about the size of a chassis.

The research process was not as simple as Yu Xian had imagined, but overall it went relatively smoothly. Considering the progress and time, a month should be sufficient.

The research on scientific ninja tools basically occupied all of Yu Xian's brainpower, so when the cooldown time of the dungeon ended, he did not blindly enter a new "Chunin Exam" dungeon... Before completing this research, he did not have any spare brain cells to think about the next project.

Therefore, during the research period, Yu Xian entered the Nine-Tails' Chaos instance. The things to do in the instance were relatively simple, which can be summarized as "ninja hunting".

First, attract Kakashi's attention as usual, then defeat him in a rather clever way, and then seize the Mangekyou Sharingan and absorb it with your palm.

Then, seize the opportunity to attack other Konoha ninja, continuously increasing your base stats...

Putting everything else aside, within this month, Yu Xuan finally mastered the Earth and Water Release chakra nature transformations, becoming a ninja with all five elements.

Through hard work and struggle, he finally caught up with the starting point of some ninjas.
