Chapter 184: New Perfect Grade Skill

【Disciple Might Guy's trust level increased; current trust level: four.】

【You gifted the disciple a collection of taijutsu training insights. The disciple was extremely grateful. Super critical hit! Reward obtained: Armament Haki (Perfect Grade).】

Compared to the reward from Shisui, this one was slightly less, but that was understandable—after all, Might Guy wasn't from the Uchiha clan; no matter how emotional he got, he couldn't unlock a Sharingan to boost his strength.

Overall, however, Mu Yue was quite satisfied with the harvest. Might Guy's trust level was maxed out, so from now on, his chakra growth would be four times the normal rate, just like Shisui's. On top of that, he had also obtained a Perfect-grade skill.

A Perfect-grade skill was extremely valuable. Putting aside everything else about Hiruzen Sarutobi, Mu Yue acknowledged his strength. Even with that vast library of skills, Hiruzen only had one combination ninjutsu that came close to Perfect-grade.

What's more, this Perfect-grade skill turned out to be the Armament Haki that was practically a must-have for the powerhouse from another world—so even better.

Based on the localized skills the system had provided so far, Mu Yue speculated that when the system localized a skill, it considered the skill's strength in its original world.

Take the Breathing Techniques from Demon Slayer, for example: without them, it was impossible to fight demons. Their importance was obvious. As a result, after localization, those Breathing Techniques were all at the level of forbidden jutsu.

On the other hand, skills at the level of Shave and Finger Gun, while decent in the original world, weren't considered that important. So after localization, they were merely adequate taijutsu—nothing that significant.

A flood of memories related to training in Armament Haki surged into Mu Yue's mind, as if he had trained that skill for decades in an instant.

After receiving the training memories, Mu Yue immediately judged that this was an extremely practical Yin Release secret technique.

Once localized, Armament Haki belonged to Yin Release. The intensity of the Haki was related to the user's mental strength and chakra strength.

At the basic level, Armament Haki could be used for Hardening—that is, using Yin Release nature transformation to create a layer of black substance covering any part of the body. This could both enhance defense and increase attack power, and it could also be applied to kunai and shuriken.

Once proficient, the user could perform Armament Coating and Emission. Coating involved wrapping special Armament Haki chakra around the limbs to strengthen power, and it could be stacked with Hardening. Emission involved directly releasing the Yin Release chakra of Armament Haki outward, similar to how Fire Release spews fire or Water Release spews water.

At the expert level of Armament Haki, the user had absolute control over the Haki on their body, allowing them to concentrate the Haki on a single point for ultimate defense or ultimate offense.

As for the Perfect grade, it comprehensively improved the quality of the Haki. As long as the chakra supply was sufficient, even the hardest ninjutsu couldn't break through. With Haki reinforcement, one punch could split heaven and earth.

Going over the usage methods of Haki in his mind, Mu Yue even felt that Might Guy could try learning it.

Although it was a secret technique, Armament Haki was the type where raw power carried it through. Before reaching the expert level, there was no fine control needed. Mu Yue thought that Might Guy wouldn't be able to reach the expert level anyway. Given Guy's ninjutsu talent, even with the Teaching skill, it would be very difficult to bring him to expert level.

Reaching the basic level counted as success; reaching the proficient level counted as a profit. After all, when Might Guy opened the Eight Gates, he didn't have many things, but he had plenty of chakra. He could just pour in chakra fiercely, covering his whole body with high-intensity Armament Haki. That would be both tough and high-output.

"Even if he can only use Hardening, that's still a huge boost," Mu Yue thought to himself.

The fundamental reason for being unable to use ninjutsu after opening the Eight Gates was that the chakra became too violent to meet the standards for performing ninjutsu.

But this Armament Haki secret technique… how to put it? It wasn't a specific ninjutsu—it was a method of applying chakra.

Take the Nara clan's Shadow secret techniques as an example: the core was also Yin Release nature transformation, while Shadow Imitation Technique, Shadow Sewing, and Shadow Stitching were specific ninjutsu.

Mu Yue didn't need Might Guy to use Haki in fancy ways or turn it into a ninjutsu. He only needed Might Guy to be able to use Hardening.

Still, Mu Yue wasn't sure if it would work, since no experiments had been conducted yet. He just felt there was a chance of success.

After everyone had given their gifts, the next steps were blowing out the cake, making wishes, and the rest of the usual process.

"My birthday is on February 10th—just over a month away. Everyone should come then too!" Obito reminded with a goofy smile while eating cake.

"Right now it's still Guy's birthday, Obito. You're too impatient," Rin Nohara said helplessly.

Promoting his own birthday while celebrating someone else's—probably only Obito would do that.

"Hehe, seeing everyone so happy, I just couldn't help blurting it out," Obito chuckled.

Obito was looking forward to it, and Mu Yue was also looking forward to it. After all, opportunities to massively farm rewards like this were rare.

Mu Yue felt it would be slightly easier to farm rewards from Obito than from Might Guy.

Although neither of them lacked elder care as much as Shisui did, when broken down further, there was a big difference: Might Guy had his father, while Obito had his grandmother.

Obito was willing to help others, but he didn't treat everyone the same. On the contrary, Obito was the type of person who, the better you treated him, the deeper his feelings for you would grow.

The way Obito went straight to becoming a twisted psychopath after seeing Rin die in the original story gave some clues.

Rin had been looking after Obito ever since before he started school. When Obito was late for enrollment, it was Rin who delivered his enrollment materials. After that, she took care of him in various ways, all the way until her death under Madara Uchiha's scheme.

So, for his big plan to farm Obito's rewards, Mu Yue intended to make Obito see how seriously he took Obito's birthday from the very start—the care he put into preparing the gift, and the meticulous attention he showed toward Obito.

"Just make sure you don't show up late on your own birthday," Kakashi said flatly.

"You're the one who'd show up late on your own birthday!" Obito retorted, then remembered that he hadn't yet told Rin how Kakashi had dropped the ball on a mission.

"Rin, let me tell you—don't think Kakashi is a chūnin while Guy and I are still genin. Actually, when it comes to doing missions, Kakashi is less reliable than we are."

"At that time, after we entered the Land of Fields, we encountered enemies. I held off a powerful enemy ninja, Gai worked hard to protect the client, and only Kakashi was being a burden to Teacher Muyue, frozen in place and unable to move."

"Obito seized the opportunity to slander him relentlessly, leaving Rin at a loss for words."

"Kakashi's face darkened. Obito didn't mention the strength of the enemy he was controlling at all, instead boasting about how strong the ninja he faced was."

"Since Obito was so biased, Kakashi didn't hold back either, recalling various details from that time to viciously attack Obito."

"The room instantly became even livelier."

"By the time it ended, Kakashi and Obito were still verbally reviewing that battle, each looking for flaws in the other's performance."

"Meanwhile, Muyue went alone to the Southern Border Forest to test his new ideas."
