Naruto: The Primal Hyuga Pierces the Shinobi World.

Although the Eight Gates Formation is only the basics, this technique has an incredibly terrifying effect on Shinichi's strength.

With the door open, his strength is not inferior even when facing "normal" Kai, and his speed and reaction are also greatly improved.

After the brain's limitations were unlocked, Shinichi's brain processed information much faster. With the Byakugan's unobstructed vision, Shinichi was able to react to almost everything happening around him in a timely manner.

Although it was just the opening of the gate, Shinichi's strength increased several times over, and the difference from his normal state was not just in the amount of chakra.

After Shinichi entered the Open Gate state, Might Guy also stopped holding back. Although he did not use the Eight Gates Formation like Shinichi, he still brought his taijutsu abilities to the extreme at this stage.

Two figures crisscrossed the training ground, with strong gusts of wind occasionally whistling outwards.

Aburame Shiki and Uchiha Shisui, who were watching from the sidelines, also silently stood up and retreated to the outer edge.

The fight was quite loud, and the two were moving so fast that even with Aburame Shiki's sharp eyesight, she couldn't see all their movements.

Shisui, on the other hand, silently activated his Sharingan and took in the battle between Shinichi and Guy.

Although he didn't personally participate in the battle between the two, Shisui was still able to learn a lot from their fight thanks to the Sharingan's ability to see through things, even though he couldn't replicate the Eight Gates technique.

With the door open, Shinichi's stamina was being depleted at an alarming rate. The battle lasted only half an hour before ending with Shinichi exhausted.

However, Kai's condition wasn't very good at the moment. His body, clad in a green bodysuit, was already soaked in sweat. He had been hit several times during his battle with Shinichi, and as the battle ended, the pain became increasingly clear and noticeable.

After Shinichi entered the open state, even Guy couldn't find any openings in his opponent's defenses. At most, Guy managed to land a few punches on Shinichi.

However, even an attack of this magnitude was a "heavy blow" for Shinichi.

As he exited the Eight Gates Formation, a strong sense of exhaustion washed over him. At the same time, his muscles ached, and some areas felt faintly painful.

Under the Byakugan's observation, Shinichi could clearly see his current physical condition. His meridians and muscles had not been damaged by the Eight Gates, and the pain was merely subcutaneous bruising.

Pain and fatigue did not diminish Shinichi's enthusiasm for training; on the contrary, he quite enjoyed the feeling.

In his eyes, this was a feeling called "elevation".

"Bang!!"

Shinichi lay on the ground with his head tilted back, panting heavily, white sweat steaming out like an overheated engine in winter.

Might Guy, exhausted, plopped down on the ground, glanced at Shinichi not far away, and laughed heartily:

"This is what youth is all about!"

Might Guy also enjoyed the battle with Shinichi, as battles between ninjas always involve the use of ninjutsu and ninja tools.

In a pure physical combat like this, there are probably very few people in Konoha who can fight him now.

Might Guy was also looking forward to Shinichi growing up quickly, and he also wanted to get familiar with the use of the Eight Gates during his daily training.

Although this technique has strong side effects after use, the more doors opened, the stronger the power gained, but also the stronger the side effects.

However, a secret technique is a secret technique. Even if it has significant side effects, as long as it doesn't open the gate of death, it can always be restored.

Moreover, given Might Guy's abilities, he doesn't need to worry about side effects at the current level of opening the fifth gate. At most, he might experience intense muscle soreness after closing the Eight Gates, just like Shinichi, but that level of side effects is nothing to him.

Any technique requires constant use to master, and Kai also wanted to familiarize himself with the combat state under the Eight Gates.

Whether it's strength, speed, or reaction ability, there are always huge differences between the normal state and the Eight Gates Formation, and he must be familiar with the different abilities he displays in these two states.

Here, have some water.

Aburame Shiki came to Guy's side with a water glass. Might Guy also turned his gaze away from Shinichi, took the water, gulped down a mouthful, and then let out a long sigh.

On the other side, Shisui also handed water to Shinichi, who sat up, thanked him, and accepted it with a smile.

A cool breeze rustled through the trees.

Shinichi narrowed his eyes slightly, thoroughly enjoying the time he spent training and fighting alongside his comrades.

"How about it? After resting for a while, how about we practice some Fire Release ninjutsu?"

Seeing Shinichi's comfortable expression, Shisui couldn't help but smile and ask.

Shinichi's daily training is not limited to taijutsu. His chakra nature is most suited to fire and lightning. Coincidentally, there happens to be an expert in fire-style ninjutsu in the team.

Although the Hyuga clan is a powerful clan known for its ninjutsu and taijutsu, Shin Hyuga does not insist on using taijutsu to solve battles.

Both Guy and Shisui were truly good people. When Shinichi wanted to learn the Eight Gates, Guy would help him without expecting anything in return. And when Shinichi wanted to learn Fire Release ninjutsu, Shisui also had no intention of hiding anything from him.

During this time, Shinichi had already learned a lot of ninjutsu, including the Uchiha clan's signature non-killing technique—the Great Fireball Technique.

Upon hearing Shisui's question, Shinichi shook his head after catching his breath.

"I have some ideas that I'm planning to test."

"If all goes well, I'm afraid I'll be able to develop a new technique that suits my use."

Shinichi had always had the idea of ​​developing new techniques. Although he had Gentle Fist, Fire Release ninjutsu, Eight Gates, and Flying Thunder God, Shinichi always felt that he lacked a powerful offensive ninjutsu that could deliver a decisive blow.

Even the Fourth Hokage, who wasn't good at attacking, had the Giant Rasengan as one of his trump cards.

Shinichi's predicament is actually similar to that of the Fourth Hokage before he developed the Rasengan.

When Shinichi was sparring with Shisui and Guy, he accidentally used the Rotation Technique in mid-air. Shinichi believed that its destructive power far exceeded that of the ordinary Rasengan.

The mechanism of the Rejuvenation Technique is similar to that of the Rasengan. Shinichi's ideal state for the new technique is like the Spiral Nen aura of a Qi Master in a certain toxic milk powder.

If, in addition to incorporating chakra form transformations, fire and lightning chakra nature transformations are added, the destructive power of this new technique will far surpass any unsealed ninjutsu.
