He told the system, "Extract Chuan Yu's bloodline and all his energy, and inject them into Hinata."
If Hinata couldn't take it, just strengthen her body. That ought to work, right?
The system answered, "Understood." An invisible force descended on Chuan Yu, and his body quickly shriveled at a speed visible to the naked eye.
Ōtsutsuki Chuan Yu's body instantly became a dried-out husk, every last bit of strength drained from him. All his energy gathered into a blue-green mass of light.
Uchiha Yi could clearly sense the strong characteristics of the Byakugan within that light, along with the chakra fluctuations unique to the Ōtsutsuki Clan.
He raised his hand and injected the light into Hinata. The discomfort on her face immediately vanished, and she settled down.
The system's mechanical voice immediately rang out: "Rest easy, host. Hinata's bloodline has already finished evolving. She can absolutely withstand the Giant Tenseigan's energy surge and awaken her Tenseigan without a hitch!"
But before those words had even faded, the system was proven embarrassingly wrong. Its mechanical voice abruptly changed, issuing an urgent warning: "Ding! Warning! Familiar Hinata Hyuga's body has reached its maximum capacity and cannot absorb any more energy from the Giant Tenseigan."
Uchiha Yi's brows knitted sharply. Only then did he realize that the Ultimate Sharingan System actually had two operating modes. They weren't two separate systems, merely a mechanical core and an intelligent control center. All routine notifications came from the core system.
His expression darkened, and anger immediately flared. The system's intelligent voice piped up: "How was I supposed to know? How did the energy exceed her limit?"
Soon, however, the system completed its analysis, and its mechanical voice regained its calm: "Host, this system's analysis indicates that the problem lies with Hinata Hyuga's Byakugan. Her Byakugan had already evolved to a peak state approaching the Tenseigan, so she needs very little energy to awaken it."
Uchiha Yi slapped his forehead, suddenly understanding. Right! Ōtsutsuki Chuan Yu's Byakugan hadn't evolved into the Tenseigan, but it was already the pinnacle of the Byakugan. Hinata's Byakugan shared his bloodline, so naturally, hers was also on the verge of becoming a Tenseigan. She didn't need a massive amount of energy at all.
He panicked for a moment, but then something occurred to him, and he shouted at the system, "Are you stupid? If Hinata can't absorb it, can't you absorb the remaining energy?"
The system's intelligent voice paused, then sounded enlightened. "Oh, right! Why didn't I think of that?"
Uchiha Yi didn't know whether to laugh or cry at its reasoning. It should have thought of that ages ago. Still, another concern nagged at him: would this affect Hinata's awakening?
The system's mechanical voice said calmly, "It won't. Hinata Hyuga has sufficient Eye Power. Her Tenseigan awakening is a certainty. Besides, there's still time to absorb the energy after she finishes awakening. There will be no problems."
Uchiha Yi let out a breath of relief, his anxious heart finally settling.
By then, Hinata had already changed. Her presence was absurdly powerful, and her chakra reserves had surged to an astonishing level, no less than the One-Tail's-and they were still climbing.
Bloodlines really were the foundation of the Naruto World. The purer the bloodline, the greater the strength. This was especially true of kekkei genkai. Even among members of the same clan, differences in bloodline purity could create a world of difference in the power of their kekkei genkai. Uchiha Yi was the best example.
As he pondered this, Uchiha Yi suddenly froze. Was that... chakra mode?
Sure enough, a moment later, Hinata's feet left the ground, and she floated in midair. When she opened her eyes, they were a pair of glowing blue Tenseigan. But before Uchiha Yi could celebrate, she hurriedly closed them again.
"Yi, I... I can't open my eyes."
Hinata clutched the hem of her clothes, her face bright red and tinged with panic. Her voice was barely louder than a mosquito's hum.
Uchiha Yi smiled and reassured her, "Don't worry. That's normal. You just awakened your Tenseigan, and you're adjusting to your Eye Power. It'll pass after a while."
The system added, "Rest assured, host. The Tenseigan Hinata awakened is more powerful than Otsutsuki Toneri's. Because it evolved from her own bloodline, her adjustment period will naturally be longer."
"Oh... so that's why!"
Hinata nodded, completely reassured. She had always trusted Uchiha Yi's words.
Only after Hinata had fully adjusted did Uchiha Yi begin absorbing the Giant Tenseigan's remaining energy. Although it was only a portion, there was still a great deal left. Hinata had absorbed just a small fraction of the total. Once he finished absorbing it, he gained three million proficiency points.
Naturally, his Ultimate Sharingan leveled up. He had already decided to merge the Tenseigan into it when it leveled up, so as soon as the system prompted him, he chose to fuse the Tenseigan.
Ding! Congratulations, host! Your Ultimate Sharingan has leveled up. Current level: 7 (1,251,600/100,000,000). Due to the fusion with the Tenseigan, your Rinnegan has evolved into the Tensei Rinnegan!
Following the system notification, Uchiha Yi's eyes transformed once more, becoming a pair of deep, unfathomable Tensei Rinnegan.
Host: Uchiha Yi Ultimate Sharingan: Level 7 (possesses unlimited evolutionary potential) Familiars: Kazahana Koyuki, Sara, Hinata Hyuga (capacity: five) Skills: Eight Gates, Flying Thunder God Technique, Super Multiple Shadow Clone Technique, Fire Release, Lightning Release, Water Release, Wind Release (seven total, ten available slots) Evaluation: Young man! You now possess the Tensei Rinnegan. Your strength is outrageous, but you're still not the strongest! Hurry up and level up to become the most badass being across all worlds!
Because the Tenseigan had completely merged with the Ultimate Sharingan and become a foundation for its evolution, the Tenseigan skill had disappeared permanently. It hadn't left an empty skill slot; it had been fused directly into the Sharingan.
At level 7, the Ultimate Sharingan should have accommodated eleven skills, but now it only had ten slots. Uchiha Yi didn't take that minor loss to heart.
He could feel his Tensei Rinnegan growing stronger with every passing moment. Not only did it contain all the power of both the Rinnegan and the Tenseigan, but every ocular technique had also been enhanced and upgraded. And the changes showed no sign of stopping.
Uchiha Yi had originally thought that evolving the Tensei Rinnegan through his Ultimate Sharingan would at least make the process more stable. But now...
With his eyes closed, Uchiha Yi sighed and asked, "System, be honest. You never saw this coming, did you?"
He wasn't putting on an act to look cool. He genuinely couldn't open his eyes. His newly evolved Tensei Rinnegan had actually entered a "pulsation" phase.
The system's voice immediately exploded, "Host, watch your attitude! This system never said you wouldn't experience pulsation!"
Uchiha Yi raised an eyebrow. "Then why didn't this happen when my Byakugan evolved into the Tenseigan before?"
The system snorted. "Because that kind of Tenseigan was too weak. Giving you one was child's play for this system."
"Are you saying my current Tensei Rinnegan is beyond your control?" Uchiha Yi pressed.
The system replied with towering arrogance, "You're overthinking it, host! This system has no limits. If you have what it takes, you can reach level 100!"
"The pulsation is happening this time because the Ultimate Sharingan is enhancing you in every respect!"
So that was it. Uchiha Yi immediately understood. The system had mentioned this before: a level 7 Ultimate Sharingan would enhance every aspect of him.
Although chakra was no longer his weakness, this upgrade would probably make his chakra even more terrifying. Still...
"System, even so, you should have warned me so I could prepare!"
Suddenly entering the pulsation phase and losing access to his Dōjutsu had put Uchiha Yi in a difficult position.
"You can't blame me. You never asked!" the system said, passing the buck.
I never asked?
Uchiha Yi laughed in anger. "System, let me tell you something. You'll have no friends if you keep acting like this."
The system shot straight back, "Doesn't matter! This system isn't a living being, just an intelligent program. I don't need friends!"
Uchiha Yi: "..."
Although the pulsation currently prevented Uchiha Yi from using the Rinnegan, the Tenseigan, or even any Sharingan Dōjutsu, that didn't mean he had become a weakling.
The skills he had slotted in were more than enough to let him do as he pleased. With enhanced Fire Release, Lightning Release, Water Release, and Wind Release, plus the Flying Thunder God Technique, he was already unbeatable.
Even if he ran into Six Paths Madara now, Uchiha Yi was confident he could hold his own.
Fortunately, he had marked Flying Thunder God coordinates earlier. With his current chakra reserves, he could teleport straight back to the surface.
Hinata's pulsation phase had long since ended. Uchiha Yi had helped her work through everything, and she had gained a rough understanding of her condition.
Furthermore, Hinata's Tenseigan Chakra Mode not only allowed her to unleash Silver Wheel Reincarnation Explosion and Golden Wheel Reincarnation Explosion, but also Hamura Otsutsuki's Heavenly Imperial Guard.
The Heavenly Imperial Guard's defense was exceptionally tough. Even Uchiha Yi, as he was now, couldn't break through Hinata's Heavenly Imperial Guard.
The two of them therefore returned to Konoha shortly afterward.
In the Hyuga Clan's meeting room, the three elders became wildly excited the moment they saw Hinata's eyes.
They could even feel the bloodline suppression emanating from her eyes.
That bloodline pressure was etched into their very bones. Facing Hinata, they couldn't even summon the thought of resisting.
This alone showed that Hinata's Tenseigan was the true, orthodox Tenseigan. However powerful the Giant Tenseigan might have been, it lacked that kind of bloodline suppression.
Otherwise, Otsutsuki Tsukiya would have united the entire Ōtsutsuki Clan long ago.
Soon, however, the three elders noticed that something was wrong with Uchiha Yi.
The Third Elder suddenly spoke, a strange gleam flashing in his eyes. "Uchiha Yi, your eyes..."
Even with his eyes closed, Uchiha Yi could see his expression clearly.
"Oh, just a minor problem," Uchiha Yi answered casually.
"What problem?" the Third Elder immediately pressed.
The First Elder and Second Elder also leaned closer, their expressions tense.
Uchiha Yi smiled. How could he not know what the three elders were thinking?
Unfortunately for them, even with his eyes closed, he could still beat the entire bunch senseless!
At that moment, Hyuga Hiashi spoke.
"Yi and Hinata just got back. They must be tired. Let them go and get some rest!"
Hyuga Hiashi didn't know what had happened to Uchiha Yi, but he understood what the three elders had in mind.
Unfortunately, despite being the clan head, he had little say in front of those three elders.
"Hiashi, how can you say that? If something has happened to Uchiha Yi, that would be disastrous!" the First Elder said.
"Exactly! Hinata is our next clan head. How could I, the Third Elder, ignore something that concerns her?" the Third Elder chimed in.
Hyuga Hiashi's expression immediately darkened.
The First Elder in particular spoke in an indifferent tone. "Hiashi, we're doing this for Hinata's sake. Stay quiet for now."
Then the First Elder turned to Uchiha Yi, his tone softening slightly. "Child, don't get the wrong idea. We're only looking out for you both. After all, if something happens to you, it could affect your marriage to Hinata."
Heh, seriously... how could they twist things like that?
