Previously, no one in the Senju Clan paid much attention to the Eight Gates.
But after seeing Guy's stunning performance, the Jonin of the Senju Clan began to take it seriously.
Senju Gyokushun said, "After we return, find a way to get Guy's consent to let him teach the Eight Gates to the children in the clan who are interested in Taijutsu."
A copy of the Eight Gates was also kept in the Scroll of Seals, but it belonged to a family secret tradition.
Duy's ancestors handed it over back then because of Village policy; the Senju Clan themselves had sealed their own Forbidden Jutsu inside, so how could other Shinobi Clans not follow suit?
Only the Uchiha didn't follow; most Shinobi Clans or clans with secret traditions, such as Dan's clan and Duy's ancestors, all sealed their own Forbidden Jutsu in the Scroll of Seals.
Doing this also avoided the possibility of the family line ending one day, ensuring the Forbidden Jutsu created by the ancestors could continue.
The Forbidden Jutsu in the Scroll of Seals were not for the Hokage to dispose of at will; they required the consent of the original family.
For example, after Minato performed a great service by saving Kushina from Kumogakure, the Third Hokage determined that Minato had the talent to practice the Flying Thunder God and wanted to grant him the Flying Thunder God Technique from the Scroll of Seals.
But before granting Minato the Flying Thunder God, the Third Hokage had to obtain the consent of the Senju Clan beforehand.
Because the Flying Thunder God Technique was a Forbidden Jutsu of the Senju Clan.
The Hokage was merely the custodian or guardian of the Scroll of Seals, not its owner.
One had to respect copyright.
In fact, the Senju Clan didn't need to go through such a long process to obtain the Eight Gates; with their dominant power in Konoha, they could just ask the Hokage's faction for it.
The Hokage would give it to them without even informing Guy.
If power cannot be exercised willfully, can it still be called power?
But the Senju Clan was a clan that respected Ninjutsu copyright; since it was Guy's family secret, they would provide corresponding compensation to get Guy's consent to practice the Eight Gates.
Guy had amazed everyone, including Black and White Zetsu.
White Zetsu sensed the chakra inside Guy and said in surprise, "That kind of chakra is not something a Chunin should be able to erupt with."
Black Zetsu said, "The Eight Gates is a technique that releases the eight points in the human body that restrain chakra to temporarily gain immense power."
"When all Eight Gates are open, one can instantly gain power dozens of times greater than that of the Five Kage."
White Zetsu was even more surprised: "Dozens of times stronger than the Five Kage? Doesn't that mean he could defeat Lord Madara?"
Black Zetsu shook his head: "I don't know, but the limitations of the Eight Gates are too great. The Gate of Opening, the Gate of Healing, and the Gate of Life—these three gates are safe gates."
"The damage to the body from these three gates can be recovered through rest, but the opening of the subsequent gates will cause irreversible damage to various parts of the body."
In the original story, the injuries Rock Lee suffered during the Chunin Exams weren't entirely Gaara's fault; part of it was due to the side effects brought by the Eight Gates.
Opening the fourth gate, the Gate of Pain, causes muscles and blood vessels to be forcibly torn, bone cracks and micro-fractures, and damage to the chakra pathways.
If it's more severe, it can even damage the internal organs.
The fifth gate, the Gate of Limit, causes large-scale tearing and rupturing of muscles in the arms, legs, and torso, as well as severe shock and damage to internal organs.
The chakra meridians suffer severe damage.
That's why Tsunade stopped Rock Lee from continuing as a Shinobi after seeing his injuries; the powerful side effects of the Eight Gates would one day take Lee's life.
The most important thing for a Shinobi is the chakra meridians; even Taijutsu Shinobi need chakra to enhance their techniques.
Once there is irreversible damage to the chakra meridians, it basically signals the end of that person's career.
Black Zetsu added to White Zetsu: "If all Eight Gates are opened, it forms the Eight Gates Formation."
"But it also leads to the death of the user."
"The side effects of the Eight Gates on the body are immense, which is why it is a Forbidden Jutsu sealed in the Scroll of Seals!"
Guy's subsequent situation seemed to verify Black Zetsu's words; just after Guy finished showing off, severe side effects began to appear in his body.
Before he could endure the sixth gate, the Gate of View, for much longer, Guy's body forcibly closed it.
Guy spat out a large mouthful of blood and fell from the sky.
"Guy—!"
Ebisu and Genma ran toward the place where Guy was falling.
During the Fourth War, Guy was as fierce as a dragon and tiger; at Turtle Island, he unleashed the Daytime Tiger to defeat Kisame, and then fought against Obito and Madara on the main battlefield.
Although the spatial span between these events was large, the time span was probably less than two days.
Because the Fourth War only lasted three days and three nights!
The side effects of the seventh gate on the adult Guy were practically non-existent; although he was just an 'acorn,' his killing power was strong.
But the current Guy was still just a youth; at 14 years old, Guy could not yet fully master the Eight Gates.
His limit was the fifth gate; the sixth gate was something he erupted into by surpassing himself to protect his comrades.
Guy trying to harness the power of the Gate of View would only result in hurting himself.
"Damn it, you actually managed to hurt me!"
A furious roar came from where Satori had fallen, and then a mass of black shadows soared into the sky, sweeping toward where Guy was falling.
It was Satori.
Just now, Satori had simply been careless, with several burdens clutched in its claws that it had to protect carefully.
There were also Shinobi below with long-range attacks releasing Ninjutsu; Satori had to read their minds and predict their attack trajectories.
After shaking off the Gate of Limit Guy at the curve, Satori had stopped paying attention to him.
It didn't think Guy had anything left.
Unexpectedly, Satori had still underestimated the eruption of human potential!
Guy was actually able to erupt another gate—the Gate of View—from the high-speed state of the Gate of Limit.
The wide-range attack of the Morning Peacock had blocked all of Satori's movements, making it impossible for Satori to perform aerial maneuvers to dodge within the limited space.
But Guy only managed to wound Satori, and the injuries weren't very obvious; in a short time, relying on Satori's recovery power, the wounds from the fire fists had already healed.
Satori's stats were too high, and its margin for error was like that of a Tailed Beast.
Guy's ability to wound Satori and save Natsuhi, Kurenai, and the others was already a monumental achievement.
Now, there was no one left to save Guy.
Ebisu and Genma had no anti-air means, and even if they did, Satori's speed was so fast they couldn't react.
In an instant, Satori flew to Guy's side, its yellow-black claws pressed together like a sharp dagger stabbing toward Guy's body.
With just one strike, Guy's chest would be pierced and his internal organs torn apart.
No one in the Shinobi Allied Forces could save Guy.
Mifune rushed up to save him, swinging his famous sword Kurosawa, gathering chakra on it and releasing a long-range sword attack.
First Tachi: Blaze!
Mifune was a New School Samurai; a New School Samurai is one who keeps up with the times and learns the techniques of Shinobi in using chakra.
They can gather chakra on their swords and release attacks.
In the original story, Mifune used the Sword Art: Sky-Slicing Slash to cut off part of the roots of the Divine Tree.
And 'First Tachi: Blaze' was an original technique from the Boruto anime, performed by Mifune's personal disciple, Tsubaki Kurogane.
This move involves infusing chakra into the katana and slashing quickly to release a powerful sword shockwave slash, which is a long-range attack.
However, it still wouldn't work; as long as there was a strong intent to attack Satori, it would be automatically seen through.
Satori absolutely evaded Mifune's sword slashes.
"Damn it, I was seen through!"
Mifune could only watch helplessly as Guy was about to be skewered by Satori.
"That Taijutsu Shinobi named Might Guy is about to be killed by Satori!"
A trace of pity appeared in Nekomata's eyes.
The Forbidden Jutsu of the Eight Gates was a secret tradition of Guy's family; during the Warring States Period, Guy's ancestors had shone brilliantly with this technique.
In the original story, when Madara saw Guy unleashing the blue steam from the Gate of Wonder, he wondered—why wasn't it red steam?
This indicates that Madara knew about the Forbidden Jutsu of the Eight Gates.
