Mokgetsu first tested the Byakugan.
With a thought, he activated the Byakugan, and the world in Mokgetsu's eyes instantly changed dramatically.
Although he was looking forward, everything behind him was also within his sight. This is the most basic function of the Byakugan, a 360-degree view.
In addition, Mokgetsu could see very far, clearly observing a bug munching on leaves on a tree five hundred meters away.
As long as Mokgetsu slightly focused his gaze, his vision could penetrate through each large tree until the visible endpoint. This is the Byakugan's ability to see through things, which can also be used to observe others' chakra.
Mokgetsu used the Byakugan to observe his own body. Under the Byakugan's ability to see through, he could clearly see every chakra meridian and every chakra acupoint in his body.
Ordinary ninjas can only release Ninjutsu through their hands, feet, and mouth, but with the Byakugan, it's different. Ninjas with a Byakugan can activate all chakra acupoints to release chakra simultaneously.
The principle of the Hyuga clan's Revolving Heaven is to activate chakra throughout the body and then spin to form a spherical chakra barrier to cover themselves, known as the absolute defense.
Just by being able to activate all chakra acupoints, Mokgetsu believes that the Byakugan is more useful to him at this stage than the Sharingan. After all, he doesn't need the Sharingan to copy Ninjutsu and is not skilled in Genjutsu. As for insight, the Byakugan also provides a significant enhancement.
However, the fact that using the Byakugan changes the eyes is troublesome, and currently, it can only be considered a trump card, not to be used unless necessary.
While thinking about hiding the Byakugan, Mokgetsu discovered that the system-rewarded glasses were not as simple as he thought.
[Black Frame Glasses: Can hide significant changes around the head, increase intellectual aura to a certain degree, and won't fall or break unless the wearer voluntarily takes them off.]
Mokgetsu's first thought upon seeing the system prompt was whether these glasses could be crafted into a weapon due to their indestructibility.
But then he thought, since they're indestructible, they probably can't be re-forged. You can't use glasses as a weapon, right?
Mokgetsu deactivated the Byakugan, his eyes returning to their original blue, then he put on the glasses and activated the Byakugan again.
Something magical happened. Mokgetsu used a kunai to reflect his face and found that under the reflection, his glasses-covered eyes remained blue and unchanged.
Not only that, but Mokgetsu also noticed that changes to his hair were kept in check. No matter how much he messed it up, the reflection showed that it never got too messy, with only slight alterations.
Of course, the appearance was unchanged only in reflection; in reality, Mokgetsu could feel it was messy.
Next, Mokgetsu tested the hardness and stability of the glasses, finding them exactly as the system described: they wouldn't fall off unless he removed them, and they were truly hard.
Mokgetsu was quite satisfied with this reward, as it allowed him to use the Byakugan freely and even protect his eyes in battle.
Next, Mokgetsu wanted to test the Perfect Level Breath of Thunder.
This was Mokgetsu's first Perfect Level skill, and after recalling memories of the Breath of Thunder, Mokgetsu could only say it was quite strong.
Like the other two Breathing Techniques, the system's Breath of Thunder was localized for the Ninja World.
If the Breath of Rock is about the extremely powerful body, with the Pattern State consuming a lot of chakra to enhance the body, and the Breath of Flame is born for Fire Release, turning the user into a no-cooldown Fire Release cannon in the Pattern State, then Breath of Thunder seems to encompass both areas, strengthening the body and enhancing Lightning Release.
With the entry-level Breath of Thunder, you can perform Full Concentration Breathing with the Lightning Attribute Chakra Nature Changes to invigorate the body and enhance physical abilities, while also strengthening Lightning Release. Once mastered, it can sustain the enhancement effects for extended periods in a Constant State.
The mastered Pattern State of Breath of Thunder allows for the use of any Lightning Release Ninjutsu without hand seals, enhancing the power of Lightning Release and greatly increasing physical strength, speed, and recovery abilities.
Mokgetsu could only say Breath of Thunder is the Lightning Chakra Mode Plus, capable of invigorating the body, and it also enhances Lightning Release. Incredible!
Moreover, Mokgetsu finally understood what new abilities the mastered Breathing Technique would bring— the Transparent World.
The Transparent World might awaken without reaching Perfect Level, depending on proficiency. But at Perfect Level, it will definitely awaken.
With the Transparent World activated, Mokgetsu gained extreme control over his body, able to identify every blood vessel within, allowing him to exert maximum strength with minimal effort. Meanwhile, his chakra manipulation precision reached a new realm.
Besides mastering his own body, the Transparent World can also see through others' bodies to accurately predict opponents' next moves, and hide one's own aura to prevent others from predicting one's attacks.
To Mokgetsu, the Transparent World seemed to be an ability designed for killing, predicting opponents while preventing them from predicting him.
"Breath of Thunder, Full Concentration Breath!"
Mokgetsu altered his breathing rhythm, switching from the Constant State of Breath of Rock to Breath of Thunder. Immediately, Mokgetsu performed the Lightning Attribute Chakra Nature Changes, exploding with dazzling blue lightning.
Mokgetsu stabbed his arm with a kunai but didn't break the defense.
Following that, Mokgetsu tested his speed, discovering that under the state of Breath of Thunder, his speed was even faster than when using Soru.
After activating the Pattern, his speed was absurd, so fast that Mokgetsu didn't dare run at full strength for fear of suddenly appearing in the Main Konoha District with just a slight effort.
The benefits Mokgetsu gained from Shisui's birthday this time were too great, making him look forward to what his disciples' birthdays would offer next.
However, achieving the kind of breakthrough like with Shisui would be challenging since this time Mokgetsu had called on all his disciples to help celebrate.
This action can improve Shisui's trust while also enhancing the trust and goodwill of other disciples, but at the same time, it will increase their emotional threshold.
Because of this thought, Teacher Mokgetsu helped Shisui celebrate, so he should help me celebrate too.
After returning home, Mokgetsu activated his Byakugan and looked in the mirror, and it was just like the reflection with the kunai, his eyes hadn't changed.
Mokgetsu was completely relieved, thinking that unless he was sleeping or had the strength to sweep through everything, he wouldn't take off his glasses.
The next day, Friday, Mokgetsu got up early as usual, but this time he wore a pair of black-rimmed glasses.
He first went to the Southern Border Forest, creating several shadow clones to look after the students' cultivation.
"Teacher Mokgetsu, why did you suddenly start wearing glasses?" Obito curiously asked.
Shisui also looked at Mokgetsu, somewhat puzzled.
"I just feel like black-rimmed glasses might suit me well. What do you guys think?" Mokgetsu asked with a smile.
"They suit you very well, just a bit unfamiliar," Obito replied with a silly grin.
"Now, at first glance, Teacher Mokgetsu gives off the impression of knowing a lot and having a good temper."
"Indeed, these glasses suit you very well, Teacher Mokgetsu," Shisui nodded in agreement after taking a closer look.
"As long as they suit me," Mokgetsu nodded with a smile, then headed towards the Ninja Academy.
Although he wouldn't give up the glasses even if they didn't suit him, it's always better if they look comfortable.
At the school office, his colleagues also noticed the change.
"Teacher Mokgetsu, is there a problem with your vision?" Iketani Isamu asked.
Mokgetsu repeated the earlier answer he'd given the students.
"It makes you look more stable and intellectual, very reliable at first glance," Ueda Aya preferred the new look.
"It's really different from before," Kimura Sugihito pondered, surprised that glasses could bring such a change.
"Could it be..." Iketani wondered whether he should wear glasses on his next date to change his image.
"Don't think about it, it's just that Teacher Mokgetsu already has good qualities. Wearing glasses won't change much for you," Ueda Aya saw through Iketani's thoughts.
"How do you know, I've never worn glasses, they might suit me too." Iketani thought he could give it a try.
Mokgetsu just smiled at this without saying anything and went directly to the first-year class before it was time for class.
The first-year students were also very interested in Mokgetsu's sudden change.
Children's descriptions are always interesting, they thought Mokgetsu looked more like an adult now, and also seemed more approachable.
Seeing Mokgetsu surrounded by many students, including female ones, Hagane Kotetsu realized something and said to Kamizuki Izumo:
"Izumo, being popular with girls isn't about getting the Hokage's approval, it's about becoming a Konoha heartthrob!"
"Konoha heartthrob?" Kamizuki Izumo asked, puzzled.
"Being a Konoha heartthrob naturally means being someone like Teacher Mokgetsu - handsome, approachable, and popular," Hagane Kotetsu said.
"Teacher Mokgetsu is indeed very popular, I heard he also has a good reputation with the female teachers," Kamizuki Izumo nodded.
So, the two of them decided to learn from Mokgetsu to become Konoha heartthrobs.
Perhaps because the system rewarded him with the black-rimmed glasses, they suited Mokgetsu so well that within a few days, his disciples, colleagues, and students had all gotten used to seeing him with glasses, and no one was curious about them anymore.
On Friday night, Mokgetsu refined the intern plan he had discussed with Sarutobi Hiruzen before, planning to take it to him the next day during tutoring.
Probably due to Sarutobi Hiruzen being quite busy lately, Mokgetsu didn't see him at Asuma's house on either Saturday or Sunday afternoon.
But Mokgetsu wasn't in a hurry, as there were still two months until the end of the semester, and even if Sarutobi Hiruzen approved, they couldn't start right away.
Lately, Mokgetsu has been guiding Obito to trigger cultivation tasks related to Kakashi.
The previous cultivation task has already been settled, and if they don't start a new task, it would be quite a loss, as the task rewards are closely linked to growth in strength during the period.
As for Shisui's life tasks, they can't be handled for the time being. As a small special Jonin, particularly in educational expertise, he isn't qualified to get involved, so he needs to wait for Shisui to grow a bit more before proceeding with various actions.
