Flying Thunder God Technique Training

These are all Forbidden Jutsu that cannot be obtained through military merit, encompassing the results of various secret researches from the Warring States Period to the founding of Konoha. Any one of them could potentially change the course of the Shinobi World.

"Danzo has opened the forbidden gate!" Shuichi thought to himself. "This is exactly what the Third Hokage feared most. The Second Hokage created a bunch of strange things, and when they meet a reckless research genius like Orochimaru, who knows what kind of chemical reaction will occur?"

"Unexpectedly, before Orochimaru could become Hokage, his good friend Danzo actually gave him a huge boost, and the Third Hokage was completely unaware of their shady deal."

Finally, there's the issue of joining Root, which is also a special perk prepared for Orochimaru, transferring his task allocation authority from the Hokage to Danzo.

In this way, Orochimaru would no longer be burdened by complicated tasks. Danzo could assign him all sorts of tasks, which were actually all research tasks. However, when recording them, Danzo could write whatever he wanted. As long as he didn't go too far and occasionally showed up to fool the Third Hokage, that would be fine.

This combination of Wood Release, Forbidden Jutsu, and a significant amount of research time was simply irresistible to Orochimaru.

"What's your opinion on this?" Orochimaru still cared about the opinion of his disciple, Shuichi.

"Isn't this exactly what you've been pursuing, teacher? Then let's go!" Shuichi said calmly, though he was secretly delighted. He figured that with so many good things to offer, he could easily get by just by drinking the soup.

As long as one's acting skills are superb enough, one is a true inheritor of the Will of Fire, since no one can see it anyway.

Instead, Shuichi enthusiastically discussed Wood Release with Orochimaru. If the Third Hokage were here to see them, he would be heartbroken. This master and disciple had actually conspired to deceive him, a kind old man. Shuichi seemed like an innocent child, actually had an "evil" soul.

After returning to the village, Shuichi continued his training mission.

The Third Hokage agreed to Anko's request, but the news of her father's recent death in battle was a huge blow to the young girl who hadn't yet graduated. Therefore, it was tentatively decided that Orochimaru would take her on as a disciple after she graduated next year.

In the training ground, having prepared for the Flying Thunder God Technique for a long time, he planned to complete it in the near future. The ultimate goal of the first stage was to only have a short period of stun after the transfer, so that he would have at least one more way to escape.

"Shadow Clone Jutsu!"

A Shadow Clone appeared in the arena. Shuichi threw Kunai imbued with the Flying Thunder God Spell Formula dozens of meters away, then connected his hands with his Shadow Clone. Although multitasking wasn't difficult for him, it was better to be cautious the first time.

Since they were his own Shadow Clone, communication was seamless. They could work together perfectly with his main body simply by flowing chakra, and the two quickly assigned their respective tasks.

Shuichi's main body is responsible for opening up spaces and using chakra, Shadow Clone are responsible for connecting the spatial channels.

Both hands formed the same hand seals, and chakra began to flow, resonating with the techniques of the Flying Thunder God Kunai. Immediately afterward, the Ninjutsu was activated. "Flying Thunder God Technique!"

"Brush!"

The two vanished from their original spot in an instant and reappeared next to the Flying Thunder God Kunai not far away. Upon landing, their shoulders swayed slightly, but they quickly regained their footing after a short adjustment.

Shuichi carefully experienced the so-called sense of spatial oppression. Actually, calling it spatial pressure would be a bit of an exaggeration. It was mainly a strong force of displacement because this spatial passage was temporarily constructed and was far less stable than a large Summoning Scroll.

After thinking for a moment, he immediately said to his Shadow Clone, "Let's do it again. Increase your chakra output as much as possible."

The Shadow Clone, having inherited his memories, quickly understood his meaning. The two returned to their original spot, faced each other again, and formed Hand Seals. The Flying Thunder God Technique was activated for the second time, "Whoosh!"

Upon landing this time, it was obvious that the body was very stable. The Shadow Clone immediately noted down the details of these two landings and then disbanded to return to the main body.

After learning about his experience, Shuichi looked at the technique on the mark and quickly realized the reason after recalling Minato's explanation. "Just as I thought, Minato didn't mention this, or perhaps he forgot because it's been so long."

When the Flying Thunder God was activated for the second time, the Shadow Clone increased the amount of chakra it output several times, using most of its chakra at once, and the temporary spatial channel it constructed became much more stable.

Shuichi thus concluded that one of the key improvements Minato made to the Flying Thunder God Technique was in the reduction of chakra consumption.

The amount of chakra consumed in the first step of opening a space is calculated based on volume. When the user performs a space jump alone, this step does not consume much chakra. Therefore, the only way to reduce chakra consumption is to find a way to construct the space channel.

Based on the feedback from the Shadow Clone experience, if the amount of chakra were doubled, the stability would improve significantly.

If we consider a spatial channel as a special chakra thread connecting two ends, then the chakra consumption is related to the length and thickness of the thread.

According to Shuichi's speculation, after the Second Hokage found inspiration in the Summoning Technique, he also referenced the Contract Scroll technique for constructing spatial portals, which was highly stable but also consumed a lot of chakra.

Therefore, despite spending a lot of time on other Forbidden Jutsu, he can still use high-difficulty Ninjutsu like the Flying Thunder God Slash. After observing Minato's fighting style, Shuichi discovered that he had only recently begun to frequently use similar seamless Taijutsu attacks.

Since the Second Hokage did not consider using the Flying Thunder God as a primary means of combat, if it is only used for surprise attacks at critical moments, then of course the more stable the spatial channel, the better. Even if a lot of chakra is consumed, it can only be used once or twice in a battle.

Minato, on the other hand, decided to use the Flying Thunder God as his core fighting method after obtaining it. This kind of chakra consumption was obviously not feasible and had to be improved before it could be used.

If the Chakra Threads used by the Second Hokage Flying Thunder God to construct spatial portals were as thick as Steel Cable, then Minato changed them to be as thin as silk threads.

In this way, chakra consumption is naturally greatly reduced, and he can use it frequently in battle, accomplishing the feat of killing countless enemies and pursuing them for nearly a hundred miles, thus earning the name Yellow Flash, instead of running out of chakra after just a few strikes.

Of course, this significant reduction in chakra consumption also has drawbacks. The stability of the temporary spatial channel of the Flying Thunder God will decrease, and the surrounding pressure during spatial jumps will greatly interfere with the user.

Through years of practice and adaptation, coupled with his Shinobi World reaction speed and body control, Minato eliminated this side effect. However, this improvement was a huge challenge for ninjas who were new to the technique.

"The difficulty of adapting has increased significantly, while the chakra consumption has decreased drastically. He must have been completely used to it after using it for many years, so he forgot to tell me." After figuring this out, Shuichi decided to try Minato's Flying Thunder God Technique and see how long it would take to adjust.

Having successfully activated it twice before, he figured he could use it directly with his main body as well. He immediately began Hand Seals and channeling his chakra, unleashing the Flying Thunder God Technique once more. "Flying Thunder God Technique!"

"Thud..." After being teleported to the side of the Kunai, Shuichi was completely unsteady and almost sat down on the ground. Fortunately, he reacted quickly and braced himself with his hands.

"Wow... the impact is actually this big."

He rubbed his wrist, surprised that spatial interference had almost caused even a master of Body Flicker Technique like him to lose control. "So adding one more person significantly improved stability. Would adding three people make it even more stable?"

Shuichi immediately tried it out and found it to be true. This time, the three of them moved together and stood very steadily. "It's like my meridians have been extended by 2 times, greatly increasing the stability of chakra flow. The other two also helped to share two-thirds of the pressure on my body."

"It's really amazing. I have quite a lot of chakra. So, it's more appropriate for me to use the Flying Thunder God Technique in the style of the Second Hokage. I should expend more chakra to use it first."
