[Disciple Uchiha Shisui's trust level increased, current trust level four]
[You gifted your disciple a fairly decent homemade ninja tool. The disciple is extremely grateful and rewarded you with a super critical hit, gaining the rewards—Breath of Thunder (Perfect Level), black-framed glasses]
[Disciple Uchiha Shisui's emotions are too intense, activating the Six Paths Bloodline to awaken the Sharingan, with increased strength, gaining the reward—Byakugan]
[Disciple Uchiha Shisui Chakra +200, apprentice return boost Chakra +800]
As Mokgetsu expected, extreme emotions brought about an unprecedented explosion, revealing a skill above Master Level, along with a pair of glasses whose purpose is temporarily unknown.
However, this time Shisui's upgrade rewards are somewhat abstract. He activated his own Sharingan and surprisingly received a Byakugan as a reward. Fortunately, the system's gifted Byakugan can be controlled, and his eyes won't change in an unactivated state.
But on second thought, it's not too unreasonable. After all, both Sharingan and Byakugan were left by the Otsutsuki bloodline.
The apprentice returning boost reward from trust level four is quite powerful. Since Shisui activated the Sharingan, his Chakra increased, multiplying directly by four on Mokgetsu's side.
"The rate of Chakra increase should see a significant boost next," Mokgetsu thought to himself.
Of course, the Sharingan brings not only two hundred Chakra; the powerful spiritual energy boost will make Shisui's natural Chakra increase much faster, accelerating Shisui's growth, which equals acceleration for Mokgetsu as well.
This reward was truly maximum, and Mokgetsu could only say that the amount of effort spent was not in vain.
The increase in trust level also brought new changes to the teacher-disciple panel.
[Disciple Uchiha Shisui has gained a selectable life mission]
[Life Mission: Uchiha and Konoha]
[Main Objective: Eliminate the conflict between Uchiha and Konoha, allowing Uchiha to integrate into Konoha]
[Mission Progress: 0]
[Mission Reward: Determined by the task completion rate and strength increase during the mission, settling every ten percent of progress]
[Note 1: The mission automatically fails if the Uchiha Clan is too few in number]
[Note 2: Life mission difficulty is extremely high; once determined, it must be completed before proceeding to the next life mission. Choose carefully]
[Note 3: The greater the difficulty, the higher the reward]
Regarding the life mission appearing for Shisui, Mokgetsu fell into contemplation.
If following the original plot, there is no doubt that this mission is impossible to succeed because the Uchiha ultimately faced annihilation.
However, the annihilation in the original plot had multiple causes. Firstly, the Nine-Tails night orchestrated by Obito caused the already distrusted Uchiha Clan to be completely isolated. The isolated Uchiha sought rebellion, and Danzo, who eyed the Sharingan, naturally wouldn't miss such an opportunity.
After some thought, Mokgetsu confirmed this mission.
Even without Shisui's mission, Mokgetsu would handle Obito's issue; by preventing Obito from turning dark, the Uchiha won't fall into an extinction crisis, avoiding the direct mission failure.
In Mokgetsu's view, the difficulty of this mission is moderate, not too difficult. If it were a world peace mission, Mokgetsu wouldn't want to accept it as a first task due to its high challenge, making it unsuitable.
"Shisui, your eyes." Obito noticed Shisui's eyes turning a vivid crimson with a rotating tomoe pattern inside.
At that moment, Obito truly envied Shisui, who had received such a great birthday gift and awakened the Uchiha Clan's Sharingan.
If he had a Sharingan, how could he have lost to Guy so many times, avoiding the need to solve so many problems?
In a highly excited state, Shisui didn't pay much attention, but Obito's reminder quickly brought the anomaly to his notice.
"Is this the power of the Sharingan?" Shisui felt the world becoming incredibly clear, able to see through even the flight paths of insects.
"Don't show your Sharingan in front of others for now," Mokgetsu advised.
Gaining strength from eye awakening is a good thing, but Shisui is only just six years old, and opening his eyes at this age would create a significant impact if word got out.
Firstly, Uchiha leaders like Fugaku would pay more attention to Shisui, which isn't much of an issue and would even provide more resources to him.
The key lies in the impact outside of the Uchiha, namely Sarutobi Hiruzen and Danzo.
Sarutobi Hiruzen might simply give Shisui a "Will of Fire" education, hoping he becomes the next Uchiha Kagami.
Danzo is less predictable. His vigilance toward the Uchiha might lead him to either tightly control Uchiha Shisui as a sharp weapon for Konoha or become extremely wary of him, fearing another Uchiha Madara.
The cost doesn't justify the benefits, so Mokgetsu chose to have Shisui hide his Sharingan.
"Why? Wouldn't showing the eyes be a good thing?" Obito didn't quite understand. If he had the Sharingan, he'd surely use it often; otherwise, it would feel wasted.
"I'll explain the specific reasons to you two later; it involves the conflict between the Uchiha Clan and the village," Mokgetsu explained.
"Got it, Teacher Mokgetsu," Shisui nodded in response.
He trusted that Teacher Mokgetsu wouldn't harm him. Mokgetsu said not to showcase the Sharingan to others, so Shisui complied and wouldn't even tell his uncle upon his return.
"Let's first blow out the candles and make a wish; celebrating your birthday is the most important thing today," Mokgetsu kindly smiled.
Standing before the cake, Shisui closed his eyes and pondered his wish.
While reason told him that any wish was the same, as it couldn't come true on its own, he felt today was especially joyous, warranting a sense of ceremony.
"If possible, let life continue this way, and may the village, clan, and teachers all become better..." Shisui thought to himself.
Then Shisui opened his eyes and blew out the six candles.
"What wish did you make, Shisui?" Obito curiously asked.
"You can't ask that; saying it out loud will make it not come true," Kurenai said with a gentle smile.
After wishing came the final cake-eating phase. This time, there wasn't a cake fight; everyone joyously ate and chatted.
"Shisui, how did you suddenly awaken the Sharingan?" Obito hoped to learn from his experience.
"I don't know; suddenly, I felt a surge of special Chakra, and then my eyes opened," Shisui thought, unsure of how to describe the sensation.
"Keep training, and you can awaken your Sharingan too," Mokgetsu said while taking a bite of cake.
Opening an ordinary Sharingan is not difficult; it's the Mangekyo Sharingan that's hard to achieve.
The Mangekyo Sharingan is a big trap if you don't have Hashirama cells or upgrade to the Eternal Eye, as using it too much can waste it entirely.
Good times always fly by; the night grew darker before they knew it. After helping Shisui clean his house, Mokgetsu and the others were about to leave.
Shisui found a million ryo to give to Mokgetsu as supplemental funding for crafting ninja tools since Mokgetsu had previously mentioned spending a lot on material costs, preventing them from buying expensive ingredients for food.
Mokgetsu smiled and declined the money Shisui offered, saying:
"For a teacher, the disciple growing stronger is the best reward. If that short blade can help you gain an advantage in battle in the future, I'd be very happy."
After speaking, Mokgetsu bid farewell and left. Having received quite a few rewards, he went to test the new skills he acquired.
"To become stronger..." Watching Mokgetsu's gradually disappearing figure, Shisui still recalled Mokgetsu's words in his mind.
