Chapter 143: New Abilities of the Perfect Breathing Technique

Mutsuki first tested the Byakugan.

With a slight movement of his mind, Mutsuki activated the Byakugan, and the world in his eyes instantly changed drastically.

Although he was facing forward, everything behind him was also within his line of sight. This was the most basic function of the Byakugan, a 360-degree field of vision.

Furthermore, Mutsuki could see very far. He could clearly see a bug nibbling on tree leaves five hundred meters away.

As long as Mutsuki concentrated his gaze slightly, his vision could penetrate through each big tree until the limit of visibility. This was the penetrating ability of the Byakugan, which allowed him to see through others' chakra.

Mutsuki observed his own body with the Byakugan. With its penetrating ability, he could clearly see every chakra meridian and every chakra point in his body.

Normal ninjas can only release ninjutsu through their hands, feet, or mouth, but it's different for those with the Byakugan. Ninjas with the Byakugan can stimulate all chakra points simultaneously and release chakra.

The principle of the Hyuga Clan's Revolving Heaven is to stimulate chakra throughout the body and then rotate to form a spherical chakra shield, known as absolute defense.

Based solely on the ability to stimulate all chakra points, Mutsuki believes that at this stage, the Byakugan is more useful to him than the Sharingan. After all, he doesn't need the Sharingan to copy ninjutsu, nor is he skilled in genjutsu. In terms of insight, the Byakugan can also provide significant enhancement.

However, the change in the eyes when using the Byakugan is difficult to deal with. Currently, it can only be used as a last resort and should not be used unless absolutely necessary.

When Mutsuki thought about hiding the Byakugan, he found that the glasses awarded by the system were not as simple as he had imagined.

[Black Frame Glasses: Can conceal significant changes in the head, to some extent, enhance intellectual temperament. Once worn, they will not fall off or be damaged unless removed by the wearer]

One thought that occurred to Mutsuki upon seeing the system prompt was whether turning the glasses into a weapon would be very powerful, considering they are said to be undamageable by the system.

However, considering they are said to be undamageable, they must be impossible to remake. It wouldn't make sense to use glasses as a weapon.

Mutsuki deactivated the Byakugan, his eyes returning to their original blue color. Then he put on the glasses and activated the Byakugan again.

Mutsuki observed his face reflected in the thrown Kunai and found that his eyes under the glasses remained blue, unchanged.

Not only that, Mutsuki noticed that his vein's changes were controlled to a certain extent. No matter how much he messed it up, his veins reflected by the thrown Kunai remained relatively neat, with changes but not too chaotic.

Next, Mutsuki tested the hardness and stability of the glasses and found that they were indeed as described by the system. They wouldn't fall off as long as he didn't remove them, and they were really hard.

Mutsuki was quite satisfied with this reward. Not only could it allow him to use the Byakugan freely, but it could also protect his eyes during battles.

Next, Mutsuki wanted to test the Perfect-level Thunder Breathing.

This was the first Perfect-level skill Mutsuki had acquired, and recalling the memories of Thunder Breathing in his mind, he could only say it was quite powerful.

Similar to the other two Breathing Techniques, the Thunder Breathing provided by the system was localized to the ninja world.

If Stone Breathing was about extreme physical strength, the Mark State consumed a large amount of chakra to enhance the body, and Flame Breathing was designed for Fire Release, allowing direct transformation into a Fire Release artillery platform under the Mark State, then Thunder Breathing had a bit of a mix of both. It strengthened the body and enhanced Lightning Release.

Beginner Thunder Breathing allowed for Total Concentration Breathing to activate physical enhancement by combining with lightning attribute chakra nature transformation, while also strengthening Lightning Release. After reaching proficiency, the enhanced effect could be maintained for a long time, referred to as Constant.

With Mastery Thunder Breathing, the Mark State could use any Lightning Release Ninjutsu without seals and enhance the power of Lightning Release significantly. It also greatly increased physical strength and speed, enhancing the body's recovery abilities.

Mutsuki could only describe Thunder Breathing as Lightning Release Chakra Mode Plus; it could activate the body and enhance Lightning Release, making it quite formidable.

At the same time, Mutsuki finally learned what new abilities the Breathing Technique would gain after Mastery, which was Transparent World.

Transparent World might not necessarily awaken only at the Perfect level; it could also awaken at the Proficiency level or earlier. However, it was guaranteed to awaken at the Perfect level.

After activating Transparent World, Mutsuki's control over his body reached its peak. He could even recognize every blood vessel in his body, allowing him to exert the maximum strength with the least effort. Additionally, Mutsuki's precision control over chakra also reached a whole new level.

Apart from mastering his own body, Transparent World could also see through other people's bodies, accurately predicting their next moves. Moreover, it could hide one's own presence, making it difficult for opponents to anticipate their next attack.

In Mutsuki's opinion, Transparent World was an ability for combat, allowing him to predict his opponent's moves while preventing them from predicting his own.

"Thunder Breathing, Total Concentration Breathing!"

Mutsuki changed his breathing rhythm, switching from Stone Breathing's Constant to Thunder Breathing. Then, he performed a Lightning Release Chakra Nature Transformation, causing dazzling blue lightning to burst from his body.

Mutsuki stabbed his own arm with a Kunai, but it didn't break through his defense.

Next, Mutsuki tested his speed and found that under the Thunder Breathing state, he was even faster than when using Soru.

After activating the Mark, his speed became outrageous. Mutsuki didn't even dare to run with full force, fearing that he might end up appearing directly in Konoha's main city area with just a little exertion.

The benefits from Shisui's birthday this time were enormous for Mutsuki. He was even looking forward to what good things his disciples' birthdays would bring him next.

However, achieving the same level of benefits as Shisui did would be difficult because this time Mutsuki invited all his disciples to help celebrate.

This move not only increased Shisui's trust in him but also inadvertently raised the trust and goodwill of the other disciples. However, it would also increase the emotional threshold for the other disciples.

Because they will have such thoughts, Yumi-sensei celebrated with Shisui, so he should also celebrate with me.

After returning home, Mutsuki opened his Byakugan again and looked in the mirror. Just like the scene reflected by the Kunai, his eyes hadn't changed.

Mutsuki was completely reassured. In the future, aside from sleeping, he would probably only take off his glasses if his strength was enough to sweep away everything.

The next day, Friday, Mutsuki woke up early as usual, but unlike usual, he wore a pair of black-framed glasses.

He first went to the Southern Forest, where he sent several Shadow Clones to take care of the students' training.

"Why did you suddenly start wearing glasses, Yumi-sensei?" Obito asked curiously.

Shisui also looked at Mutsuki, somewhat puzzled.

"I just feel like black-framed glasses might suit me well. What do you guys think?" Mutsuki asked with a smile.

"It suits you well, but it's a bit unusual," Obito replied with a grin.

"Nowadays, Yumi-sensei gives off the impression of being knowledgeable and having a good temperament at first sight," Shisui added.

"Indeed, these glasses suit you well, Yumi-sensei," Guy nodded in agreement after examining them closely.

"As long as they fit," Mutsuki nodded with a smile, then headed to the Academy.

Even if they didn't fit, he couldn't give up these glasses. But it was always nice if they felt comfortable.

When he arrived at the school office, his colleagues also noticed the change.

"Yumi-sensei, are you having vision problems?" Chitani Isamu asked.

Mutsuki repeated the answer he gave to the students earlier.

"It gives off a more mature and intellectual vibe, very reliable at first glance," Ueda Aya liked Mutsuki's appearance with the glasses.

"It's indeed different from before," Kimura Sugito pondered, surprised that a pair of glasses could bring about such a change.

"Could it be...?" Chitani Isamu wondered if he should wear glasses for their next date to change his image.

"Stop thinking about it. It's just that Yumi-sensei naturally has good qualities. Wearing a pair of glasses won't change anything for you," Ueda Aya saw through Chitani Isamu's thoughts.

"How do you know? I haven't worn glasses before. They might suit me well too," Chitani Isamu felt like giving it a try.

Mutsuki just smiled and didn't say anything. When it was almost time for class, he headed straight to the classroom of Class 1-1.

The students of Class 1-1 were also very interested in Mutsuki's sudden change.

Children's descriptions are always interesting. They felt that Mutsuki now seemed more like a prince charming than before, and they also felt more comfortable and close to him.

Seeing Mutsuki surrounded by many students, including quite a few girls, Kotetsu realized something. He said to Izumo, "Izumo, being popular with girls doesn't depend on getting recognition from the Hokage. It's about becoming a handsome guy in Konoha!"

"A handsome guy in Konoha?" Izumo asked in confusion.

"Yes, a handsome guy in Konoha naturally refers to someone like Yumi-sensei, who has a handsome appearance, charisma, and high popularity," Kotetsu explained.

"Indeed, Yumi-sensei is very popular. I heard he's also quite popular among the female senseis" Izumo nodded.

So the two of them resolved to learn from Mutsuki and become handsome guys in Konoha.

Perhaps because the black-framed glasses awarded by the system really suited Mutsuki, within two or three days, both his disciples and colleagues, as well as the students, had gotten used to Mutsuki wearing glasses. No one was curious or stared at Mutsuki's glasses anymore.

On Friday night, Mutsuki refined the internship plan he had discussed with Hiruzen, planning to bring it over to him when he went for tutoring the next day.

Perhaps Hiruzen was busy lately. Mutsuki didn't see him at Asuma's house on Saturday or Sunday afternoons.

However, Mutsuki wasn't in a hurry. There were still two months left until the end of the semester. Even if Hiruzen approved, they couldn't start right away.

Lately, Mutsuki had been guiding Obito through training tasks related to Kakashi.

The previous training task had been settled. If they didn't start a new task, they would lose out, as the rewards for the tasks were closely related to the growth of their abilities during that period.

As for Shisui's life tasks, they couldn't be done for the time being. He was just a small Special Jonin, specializing in education, and wasn't qualified to participate. They had to wait until Shisui grew a little before they could proceed with various operations.
