Even Ren's grandfather probably did not know about this. Moreover, Ren's father had set a condition for activating this eye technique: whenever he saw a member of the Uchiha Clan with a Three-Tomoe Sharingan, the eye technique would activate and kill them.
It was like how, in the original story, Itachi Uchiha had set Amaterasu within Sasuke's eyes.
Itachi Uchiha had placed Amaterasu in Sasuke's eyes to deal with Obito Uchiha. Ren's father had set up three eye techniques to deal with Madara Uchiha. Ren's father hated Madara Uchiha beyond measure because Madara had taken his mother from him. Thus, Ren's father had arranged for the seal to activate whenever he saw a member of the Uchiha Clan, and for the eye technique to trigger upon seeing a Three-Tomoe Sharingan.
It seemed that Madara Uchiha's Sharingan was almost never deactivated. It remained in its Three-Tomoe Sharingan state at all times, which was why Ren's father had set it up this way.
Who would have thought that Ren would see Fugaku Uchiha today—and that he had actually awakened a single Tomoe. This triggered the eye technique sealed by Ren's father, but it did not activate, perhaps because Fugaku's Sharingan was not a Three-Tomoe Sharingan.
Ren learned these things from some of the memories within the seal in his eyes, and naturally, he was furious!
"Phew... This is completely screwing me over. If I'd killed Fugaku right there in the classroom, that would have been a real mess. Although Fugaku only awakened his one-Tomoe Sharingan at the age of ten, awakening the Sharingan at ten was still considered pretty talented for this time." Ren was annoyed, and inwardly felt that his father was an idiot.
Final Hope
"Phew..."
Ren let out a breath and stared at the crystal before him. His blood-red eyes slowly returned to their original black.
Ren shook his head. "I can control it, but only three times!"
His faint words carried a trace of delight. Ren's father had to be credited with leaving him a fine gift, one he could control. The three eye techniques left behind by Ren's father had originally been meant to activate directly whenever they encountered a Three-Tomoe Sharingan.
Who would have thought that encountering Fugaku Uchiha's one-Tomoe Sharingan today would trigger the eye technique and nearly kill Fugaku? Fortunately, it had not happened, and Ren had now brought the eye technique under control.
Perhaps Ren's father had been too weak and had not mastered the Sharingan perfectly. Therefore, Ren felt that the three eye techniques sealed within his eyes had now lost control—lost his father's control. The three eye techniques were now like Sealing Scrolls, Sealing Scrolls capable of releasing ninjutsu and controlled by Ren.
Ren stared at his now-black pupils. "Though I'm a little unhappy about it, getting three Mangekyō Sharingan eye techniques for nothing still counts as three killing moves."
As he muttered to himself, he understood that the three eye techniques in his eyes were definitely three means of saving his life.
Ren let out a breath and looked across the vast palace, but did not see a single dog.
"Forget it... I'll come back tonight and take another look. I should head back first!" The moment he finished speaking, Ren directly reversed the Summoning Technique and vanished from Beast King Mountain.
Bang...
A cloud of white smoke appeared, and Ren stepped out from within it.
Ren looked over the silent dance classroom. "I'm back! Good thing nothing major happened!"
Then Ren walked out of the dance classroom and headed toward his own classroom.
Not long after, he stepped into the classroom and found it utterly silent.
Ren glanced around. "What's going on? Where did everyone go?"
Only Mikoto and Kushina Uzumaki remained; all the other students were gone.
Kushina ran over, looked at Ren, and nodded. "Mm... Nothing's wrong. Looks like you woke up."
Ren smiled awkwardly. It seemed Kushina really believed his excuse about going to sleep earlier.
Mikoto looked at Ren, her eyes filled with a trace of confusion, but she still said, "This is an outdoor class. The other students went outside. The two of us stayed here to wait for you!"
Hearing that, Ren smiled. "I'm fine now, so you don't need to worry. Since it's an outdoor class, let's go outside and have some fun too!"
With that, Ren turned and walked out of the classroom.
Mikoto and Kushina followed him out. However, as soon as Ren left the school building, he saw Nawaki approaching him, his face covered in dust.
Nawaki was covered from head to toe in dirt and had some injuries as well, yet he was still laughing heartily. Looking at Ren, Nawaki said, "Brother... What a pity. If you'd come out earlier, you could've seen me show off my might and beat Fugaku Uchiha senseless!"
His arrogant words were brimming with pride.
Ren chuckled. "You beat up Fugaku? That must have been quite a sight. But if Sister Tsunade finds out, you're probably in for it again."
He had become familiar with Nawaki over the past few days, so he had learned quite a bit about Tsunade. For instance, Tsunade was strongly opposed to Nawaki using violence and often lectured him on being polite and becoming a perfect handsome young man.
When Ren learned this, he had nearly burst out laughing. Polite? Just look at Tsunade herself. She was so violent, yet she wanted Nawaki to be polite. That was simply unrealistic.
At the thought of Tsunade, a trace of resentment appeared in Ren's eyes. She was still coveting his Qilin Resin!
While Ren was thinking about Tsunade, he had no idea that Tsunade was thinking about him as well.
Inside a silent cave, Tsunade spat out a mouthful of blood, her voice filled with despair. "No... Ōnoki is too strong. We're no match for him at all!"
Jiraiya was panting heavily, his body covered in wounds as well. "Ōnoki has already left, but we've all been severely injured. How can we escape?"
Orochimaru shook his head. "Difficult, far too difficult. We infiltrated the Land of Earth and ventured deep into its heart. To escape, we have to face pursuit from the Earth ninja within the Land of Earth. If we were all at our peak, there might still be some hope, but Tsunade is already..."
At this point, Jiraiya was filled with fury and looked at Tsunade with reluctance.
Tsunade's abdomen had been pierced through, and blood continued to flow. If not for the Senju Clan's powerful vitality, Tsunade should already have died.
At that moment, Tsunade smiled faintly. "You two should leave quickly. While I still have some ability to move, I can hold some people back. Leave quickly. Take the intelligence back with you!"
Orochimaru's pale face remained cold, but there was some reluctance in his eyes. The current Orochimaru was not the Orochimaru of the future; he still valued friendship greatly.
Jiraiya was the same, his eyes bloodshot. "No... If we die, we die together. If we live, we live together."
As soon as he finished speaking, a terrifying tremor shook the cave.
A roar came from outside the cave, and countless rocks crashed into it.
Orochimaru stared at the small snake on his fingertip. "We're surrounded. There are around three hundred Earth ninja outside. Most of them are Chunin, with only three Jonin. But with our current strength, breaking out is nearly impossible! Especially with Tsunade in her condition!"
Tsunade's eyes were filled with despair. "Maybe we're really going to die this time. After you return to the village, please help me take care of my little brother!"
After speaking, Tsunade had already prepared herself for death. Yet Jiraiya said, "Tsunade... Try that. Try Ren's medicinal ingredient. If it works, we might still survive!"
Orochimaru shook his head. "That kid's medicinal ingredient? But Tsunade's abdomen has been pierced through. No matter how potent it is, it won't help!"
Tsunade chuckled. "Let's try it! Ren treasures this thing greatly. He even said I'd have to repay him for the rest of my life. If I survive this time, so what if I spend the rest of my life repaying him? Haha..."
As her words fell, Tsunade took out the Qilin Resin from her backpack and slowly swallowed it.
Tsunade's Outburst
"Is this a miracle?"
