Kapitel 190: Chapter 190: Guy Opens the First Door
"Do you think I'm fast?" Mutsuki asked Kakashi.
"Very Fast" Kakashi immediately nodded in response.
Mutsuki was definitely the fastest ninja he had ever seen. When Mutsuki burst into true speed, Kakashi couldn't even see where Mutsuki was.
"If you can master the jutsu I'm about to teach you, then you can become as fast as me," Mutsuki said with a smile.
Kakashi had a very good talent for lightning attribute chakra. Among the breathing techniques he currently mastered, Thunder Breathing was the most suitable for Kakashi.
As for Kakashi's reaction issue, that could be solved with serious practice.
The Fourth Raikage could be extremely fast with Lightning Release Chakra Mode when facing Flying Thunder God, and he had no reaction problems because Lightning Release Chakra activated the nerves. Thunder Breathing was no worse than Lightning Release Chakra Mode and could achieve the same results.
If Kakashi really can't learn this microcontrol, Thunder Breathing can also enhance the power of Lightning Release, and everything will be solved when he achieves Transparent World.
"The jutsu I'm about to teach you can be called a forbidden technique. It will be very difficult to learn, so be prepared," Mutsuki reminded with a serious expression.
He needed Kakashi to know how powerful what he was teaching was, to make Kakashi feel grateful.
"A forbidden technique!" Kakashi looked surprised. He didn't expect that less than half a month after becoming Mutsuki's disciple, he would encounter a Secret Jutsu yesterday and now have to learn a forbidden technique today.
"Does Yumi-sensei actually know my father?"
Mutsuki's generosity made Kakashi suspect whether Mutsuki had a close relationship with his deceased father, so he took care of him like this.
Teaching a high-level ninjutsu Secret Jutsu forbidden technique as casually as a C-rank ninjutsu, he had mixed several teams and had never seen such a situation.
"The name of this forbidden technique is Thunder Breathing, and its core is to strengthen oneself through highly concentrated breathing."
"When you master Total Concentration Breathing of Thunder Breathing, you can instantly increase the speed of Lightning Release Chakra Nature Transformation, and at the same time, you can use Lightning Release Chakra Nature Transformation to activate cells to enhance explosive power," Mutsuki explained.
"Enhance Nature Transformation and activate cells?" Kakashi's face under the mask instantly became extremely surprised. He had heard of activating cells, but enhancing Nature Transformation was unheard of.
However, as Kakashi listened to Mutsuki's words, he suddenly remembered the times when he fought Guy and Obito, and they both suddenly unleashed tremendous power.
"Have Obito and Guy already learned this?" Kakashi asked after some thought.
"They have also learned Breathing Techniques, but different from yours, they are two other types of Breathing Techniques," Mutsuki didn't conceal it and directly told Kakashi the truth.
"Obito learned Flame Breathing, which can enhance mainly Fire Release and some physical abilities. Guy learned Stone Breathing, which cannot enhance any nature, but greatly enhances physical capabilities."
Kakashi was dumbfounded. He didn't expect that such a powerful forbidden technique would have several variations, and Mutsuki had mastered them all.
Now it was confirmed. He had previously noticed how exaggerated their progress was, how every time they met, there was significant improvement in strength.
If it was a powerful ninja like Mutsuki teaching them, then it made sense. Based on Kakashi's learning experience of over ten days, Mutsuki was indeed a skilled teacher.
"If you learn Thunder Breathing quickly, I can also consider teaching you other Breathing Techniques," Mutsuki said with a smile.
Different Breathing Techniques were not conflicting. The reason he didn't teach students more Breathing Techniques was because it required too much investment of energy, which wasn't worth it for the time being.
"Enough talk. Next, let me show you the actual performance of Thunder Breathing," Mutsuki switched to Thunder Breathing and immediately entered a state of total concentration, taking Kakashi with him for a run in the forest.
When Mutsuki put Kakashi down, Kakashi couldn't even stand properly.
Kakashi leaned against a tree, shaking his head. In just a few short minutes, he felt like he had explored the entire Southern Forest.
"Of course, besides speed, all Breathing Techniques, when practiced to a certain level, can enter the corresponding Chakra Mode. Thunder Breathing's Chakra Mode allows the use of any Lightning Release Ninjutsu without seals, enhancing the power of lightning, as well as activating cells throughout the body."
After Kakashi had recovered a bit, Mutsuki and Kakashi briefly discussed the true power of Breathing Techniques. Only by mastering the Mark could a Breathing Technique truly become a forbidden technique.
Then, Mutsuki entered the state of Thunder Breathing. With extreme concentration of breath and continuous bursts of chakra, Mutsuki's whole body was surrounded by dazzling blue lightning, as if wearing armor made of lightning.
"Lightning Release: False Darkness!"
Without forming seals, Mutsuki simply opened his mouth and unleashed a powerful lightning strike, instantly destroying a large area of trees.
Then, with a grasp into the void, a large amount of blue lightning continuously generated, forming a thunder spear directly. Mutsuki threw the thunder spear, and instantly a huge explosion sounded, creating a large crater.
In the Thunder Breathing Mark State, Mutsuki was like a thunder god incarnate, every move capable of unleashing lightning equivalent to Lightning Release Ninjutsu.
This is the power of Breathing Technique's Mark, truly the epitome of Nature Transformation. It doesn't even need seals; one can use Ninjutsu however they want.
It's undeniably powerful, but the chakra consumption is severe. With each attack, Mutsuki's chakra burned. After showing Kakashi just how formidable Thunder Breathing could be, Mutsuki swiftly exited the Mark State.
"No wonder it's a forbidden technique." As a ninja skilled in Lightning Release, Kakashi's perspective on ninjutsu had somewhat changed.
The image of Mutsuki summoning powerful lightning with just a clap was too exaggerated. Kakashi couldn't even produce such powerful Lightning Release Ninjutsu with complete seals.
Moreover, it was terrifying to think that Mutsuki also mastered other Breathing Techniques. With Flame Breathing Chakra Mode, Mutsuki could likely create a sea of fire with a breath, and with Stone Breathing Chakra Mode, Mutsuki's body would be incredibly strong.
If Mutsuki were to simultaneously use Breathing Technique Chakra Mode and then enhance it with Haki, what terrifying level of power could he reach? Kakashi could only sense that Mutsuki's power was unfathomable, making it impossible to judge his full strength.
"Let's start by learning the most basic breathing. You need to change your normal way of breathing and focus on concentrated breathing," Mutsuki began formal instruction.
Although Kakashi's strength was considerably greater than Shisui and the others when learning Breathing Techniques, his performance wasn't any better. The difference between the two sides was negligible.
[You taught your disciple Thunder Breathing, and due to their gratitude, you received a critical hit bonus, gaining proficiency in Lightning Release Chakra Nature Transformation (Proficient level).]
However, Mutsuki was quite satisfied with Kakashi's bonus. Although they were both at the Proficient level, in Mutsuki's mind, Proficient level Chakra Nature Transformation was better than Mastery level Ninjutsu.
Of course, this was excluding powerful skills like Armament Haki and Breathing Technique.
An afternoon passed, and like Shisui and Obito before him, Kakashi didn't gain any proficiency points.
After studying all afternoon without making any progress, Kakashi, who had always been quick to learn anything, felt a sense of frustration. However, with Mutsuki's reminder, Kakashi knew that Thunder Breathing was different from the Ninjutsu he had learned before, and it was very challenging. So, this feeling of frustration quickly dissipated.
As the training time was about to end, Mutsuki received some good news: Guy had finally managed to unlock the first gate of the Eight Inner Gates.
After successfully using the first gate of the Eight Inner Gates, Guy's advancement bonus was also settled.
[Under your guidance, your disciple Guy has diligently trained and gained a certain increase in strength, receiving a reward—Eight Inner Gates (Proficient).]
The advancement bonus was quite good this time. Instead of the usual piecemeal rewards, Mutsuki was directly granted Proficiency of the complete Eight Inner Gates.
Although Mutsuki rarely used the Eight Inner Gates in battle, with Stone Breathing constantly strengthening his body, Mutsuki believed that one day he would be able to open the sixth or even seventh gate without injury.
Even if it's not used for combat, teaching Guy would be excellent.
Mutsuki thought Obito would trigger the advancement bonus first, but it turned out Guy took the lead, surpassing everyone else.
"Obito's worst times are coming. Before activating the Sharingan, he won't be able to defeat anyone except Rin," Mutsuki thought to himself.
Facing Guy, who was simultaneously using Eight Inner Gates and Stone Breathing, Obito had no chance of winning. Kakashi, Obito's old rival, currently surpassed him in strength, not to mention Shisui. Among Mutsuki's disciples, although he was the youngest, he was also the strongest.
"You should familiarize yourself more with the state of opening the Eight Inner Gates. The first three gates are the safe zone of the Eight Inner Gates, so you can speed up your progress," Mutsuki told Guy.
Since Might Guy could now use the Eight Inner Gates, it was time to complete the training task.
After all, Kakashi had also become Mutsuki's disciple now. As long as Kakashi was willing to learn seriously, his strength would improve quickly. Even Pre-Beginner level Breathing Techniques could enhance his strength to a certain extent.
Mutsuki calculated the time. Guy's training task had been going on for over five months, making it the longest-spanning training task to date. He felt that the rewards after settlement should be quite good.
Furthermore, after Guy's trust level increased to four, no life tasks appeared. Mutsuki speculated that training tasks might not be able to coexist with life tasks, or life tasks couldn't be triggered during training tasks.
Guy's life task was relatively easy to guess. Mutsuki speculated that it was to become the strongest Taijutsu ninja in the shinobi world.
After about five days, Obito's advancement bonus was also settled.
[Under your guidance, your disciple Uchiha Obito has diligently trained and gained a certain increase in strength, receiving a reward—Fire Release Chakra Nature Transformation (Proficient).]
Mutsuki felt somewhat regretful. If it had been Wind Release Chakra Nature Transformation instead, then all five basic attribute proficiencies would have been above Proficient level.
In the end, this Proficient level Fire Release Nature Transformation turned into seven hundred and fifty points of proficiency, raising Mutsuki's Fire Release Chakra Nature Transformation proficiency totaling eight thousand three hundred and fifty points at the Mastery Level.
During these five days, Guy quickly became familiar with the sensation of using the Gate of Opening.
Mutsuki tested the strength of both sides and then made a comparison. Guy, who could simultaneously use Stone Breathing and Eight Inner Gates, was slightly stronger.
Without hesitation, Mutsuki arranged a combat training session for the two of them that same noon.
"Engaging in battles appropriately can better grasp the abilities learned. Today, Guy, you will spar with Kakashi, and then Obito will spar with Shisui. After the fights, take a break and then exchange opponents to continue the battles," Mutsuki said.
In addition to completing the training task, Mutsuki also wanted to motivate his disciples a bit.
He thought Kakashi probably didn't know that Shisui was even stronger than him, and Obito's memory still lingered in the phase where he believed he was stronger than Guy.
As for Rin, the current gap in strength was significant, so there wasn't much point in her joining. Watching from the sidelines should provide motivation.
"Why isn't it me and Kakashi?" Obito sighed. Fighting Shisui was really boring; he didn't even have a chance.
Moreover, he felt that his strength had improved a bit recently, so there might be hope of defeating Kakashi.
"Dear friend, be careful this time. Today, my youth is burning with extra fervor!" Guy laughed heartily, giving Kakashi a thumbs-up.
