Naruto: Gain the power of dual systems at the beginning

"Even if this technique is extremely risky, I must learn it."

Although he tried to reverse Itachi's self-righteous thinking, he didn't know whether he succeeded.

If it succeeds, then the Uchiha clan will have Uchiha Fugaku, Uchiha Itachi, Uchiha Shisui, plus him as a time traveler, four top combat powers.

It should be no problem to protect the Uchiha clan and Konoha.

But this world may be so unreasonable. Both guys, Uchiha Itachi and Uchiha Shisui, are on the side of Konoha.

Ryousuke doesn't understand what there is in Konoha worth protecting?

If Uchiha Itachi couldn't change his mind, he would have to rely on himself.

The clan leader, Uchiha Fugaku, was a coward. He was willing to be killed by his own son on the night of the genocide. That was simply a cowardly act.

In this family, he still has to protect his grandfather. After all, he is exactly the same as his grandfather in the world he traveled to. There is also a lovely woman named Uchiha Izumi. It is a pity that such a lovely girl dies. Even It’s really a sad thing to let go without fully experiencing the joy of becoming a woman.

Kai saw no hesitation in Ryosuke's eyes, which seemed to be the determined gaze of his father guarding him.

Presumably the other party also has something that must be protected, which is why he has such a look.

he said seriously.

"I am willing to teach you the eight arts of hiding armor."

Kai was aware of the relationship between Konoha's top management and the Uchiha clan, but after spending more than a month together, he believed that the other party would not be a person who would harm Konoha. This was his intuition.

Ryosuke is his best friend. If he really goes astray, Kai will activate the Eight Door Dunjia to teach him a lesson.

Although the normal combat power of the two sides is almost the same, he has been practicing Bamen Dunjia for almost 10 years.

You won't lose to the opponent easily, even if the opponent is a genius.

Ryousuke was very excited when he heard Kai's words.

Kai certainly lived up to his expectations.

"Thanks."

Kai smiled and continued.

"You can't practice the Eight Armor Armor Techniques in a place like this. After all, it's a very dangerous technique."

"Let's find another place."

Ryosuke naturally nodded in agreement.

Then the two of them came to the Hokage Rock, where there was a large wasteland.

Kai looked at this place and felt very satisfied. It was here that he taught Kakashi the Eight Gates of Armor.

Unexpectedly, I came here again to teach my second best friend the art of hiding armor.

There is a blank space here, which is more suitable for practice. After all, practicing Eight Gate Dunjia is dangerous and may even damage the surrounding areas.

There's nothing to spoil here either.

Kai looked at Uchiha Ryosuke in front of him and said seriously.

"Now I will tell you what the eight gates of armor are."

"Eight Gate Dunjia is a physical technique that temporarily gains powerful power by unlocking the channels that bind chakra in the human body."

"In the meridian system where chakra flows, the eight gates that inhibit and control chakra in the body include the door of opening, the gate of rest, the gate of life, the gate of injury, the gate of Du, the gate of scenery, the gate of surprise, and the gate of death."

"The Eight Gates will set a limit on the amount of chakra in the body, but the Eight Gates Armor-Dunning Technique can force the chakra to exceed this limit, thereby eliciting one's own power that is 10 times stronger than before."

"But while gaining power, the caster himself will also be damaged, so this is listed as one of the forbidden techniques, which is also one of the reasons why the Third Hokage ordered it to be sealed."

"He is afraid that the ninjas in the village will be addicted to this kind of power and frequently use this kind of taijutsu, damaging their bodies and affecting Konoha's overall combat power."

Ryosuke understood the reason why the Eight Gates Dungeon Technique was so powerful, but there were so few people who knew it in Konoha Village.

Next, Kai continued to introduce to Ryosuke the positions of the eight chakra suppressors, which are the positions of the eight gates: Opening Gate, Resting Gate, Life Gate, Injury Gate, Du Gate, King Gate, Shock Gate, and Death Gate.

Among them, the door of opening and closing are located on the left and right sides of the brain, the door of life, the door of injury, the door of Du, the door of scenery, and the door of surprise are located all the way down the torso.

Matt was a little hesitant when he was introduced to Death's Gate.

After experiencing the tragic situation of his father having all eight doors opened, even he couldn't bear it. It really felt like his whole body was burned.

And Ryosuke was waiting for the other party to introduce the door of death.

Kai said hesitantly.

"I don't know if I should teach you the last door, so it's up to you to decide. After opening the last door of death, people will definitely die. Do you still want to learn it?"

"study."

Ryousuke didn't hesitate at all.

He naturally knows the danger after opening the Eight Gates, but if his physique is strong enough, it is still possible to open the Eight Gates and survive.

Anyway, learn it first and then talk about it. If you can use it, use it. If you can't use it, he won't make fun of his own life. After all, he hasn't lived enough yet.

When Kai saw the other party saying this, he pointed directly at his heart and said.

"The door of death is right here. If you open it, you will definitely die, so I hope you don't open it."

Ryosuke naturally nodded.

"Don't worry, I won't joke with my life."

Kai continued to teach Ryosuke.

"Although the Eight Door Dunjia is very strong, practicing this technique is not only dangerous, but also very difficult to practice. It took me 10 years to practice to the point where I can open the Five Doors."

"Your physique is stronger than mine. As long as you are willing to endure hardships, you should be able to catch up with me in five years of training."

Ryousuke was speechless. It would take five years to practice the five sects, and he didn't have that much time.

It wasn't long before the night when the Uchiha clan was exterminated.

If he couldn't learn the Eight Gate Dungeon, he would have no trump card against Itachi Uchiha.

Even if he could convince Itachi, there would eventually be a big battle between the top management of Konoha and the Uchiha clan.

Because there is Danzo in Konoha, who inherits the will of the Second Hokage, he believes that the Uchiha clan is inherently evil, and he has deep malice towards the Uchiha clan.

Even if Naruto, the king of mouth escape, comes, he will not be able to change the opponent's will.

The Third Hokage, who secretly allowed Danzo to take action against the Uchiha clan, was also a ruthless person.

Therefore, Ryousuke is impossible and unwilling to spend such a long time learning Bamen Dunjia.

Even though he thought so in his heart, Ryosuke did not express his thoughts to Kai, but said helplessly.

"It takes five years to catch up with you Kai. You really think highly of me."

Kai said with a straight face.

"If I hadn't seen your physical strength and progress over the past month or so, I might not have such thoughts."

"Next, I'll show you how to open the first door."

At the same time, Ryousuke opened his Sharingan and observed the opponent's chakra flow and the impact area.

He needs to carefully look at all the details of the other party, not missing anything, and he should be able to learn it quickly.

When Kai saw Ryousuke's behavior, he understood immediately and couldn't help but feel a little envious.

How could he forget this? Ryosuke has the Sharingan and can observe the meridians and chakra flow of the human body.

He may be learning faster than he expected.

I sighed slightly in my heart, this may be the convenience of genius.

Then he made fists with both hands and began to refine the chakra, controlling them to hit the door opening on the left side of his brain.

Then a vein popped out on his forehead.

He explained to Ryosuke.

"This is the first door of the Eight Doors Dunjia. It removes the limitations of the brain and achieves the effect of exerting 1% of the body's abilities. It overloads the body's energy and increases strength and speed."

Ryosuke could feel that the other party's aura was becoming more intimidating.

Kai asked with a smile on his face.

"Ryosuke, you have the Sharingan, so you should have seen how I operate it."

His teammate Kakashi relied on the Sharingan to copy many ninjutsu, but Ryousuke was an authentic Uchiha and was more accustomed to those eyes, so he should be able to see clearly.

Ryosuke nodded, while he focused on another question.

"I see it clearly, but how do I turn it off after it's turned on?"

The opponent's veins are bursting out. If this state is maintained, it may be a big burden. If it is left open for a long time, it may even cause serious harm.

Kai said with a smile.

"This is simple."

"As long as you stop chakra refining, without chakra to support it, the door will naturally close."

After saying that, he stopped refining chakra. Without the support of chakra, the door opened returned to its original size, and the veins on his forehead disappeared.

Ryousuke opened his Sharingan and saw everything clearly.

It’s so simple, so the key point is to open the door.

"I understand, let's give it a try."

After saying that, Ryousuke followed Kai's example and made fists with both hands, while refining the chakra in his body and manipulating the chakra to open the door.

At the beginning, I felt a blocking force that could not let the chakra pass through for an instant.

This should be the limit for opening the door.

Then he continued to refine chakra and rushed towards the door.

The door opened slightly.

But before Ryousuke could feel happy, he felt pain coming from his brain.

The sudden pain caused him to stop refining chakra, and he naturally closed the door.

But the unforgettable pain still remained in his memory.

The pain was like a needle pricking his brain.

After all, opening the door is located on the right side of the brain.

Chapter 29 The Difficulty of Eight Gates

Ryousuke felt the unbearable pain, and his face kept changing, but he still decided to continue practicing.

Because this is the trump card to deal with the night of genocide, and it is also the only trump card that can be mastered at this stage. Some of these things must be done.

He continued to gather chakra to attack the door, but when the door opened a little, the needle-like pain hit him again.

Ryousuke endured the pain for only two seconds before reluctantly stopping the chakra refining.

This kind of pain is different from the general pain in the internal body. It is like a mental pain, which makes Ryosuke unable to concentrate on refining chakra.

He looked at Metkai and said a little helplessly.

"This is too painful."

Kai said with a smile.

"This technique is quite difficult, otherwise I wouldn't be able to open five doors now. Every time I open one door, the pain will become stronger and stronger."

"But Ryousuke, your physical fitness is not inferior to mine, so you must be able to withstand this kind of pain."

"Once you get used to this kind of pain, it won't hurt that much anymore."

Ryosuke felt a little relieved after hearing the other party's words.

If it hurts so much every time I activate it, it's okay if I don't learn the Eight Gates of Dunjia.

He continued to refine chakra and blasted open the door.

As the door opened wider and wider, the pain became more and more intense, almost like a cracking feeling like a girl's one-legged legs.

It made him break into a cold sweat.

If he hadn't been training with Kai for a period of time before, his body's pain tolerance would be greatly enhanced.
