After the Uchiha clan massacre, only Sasuke Uchiha remained as an orphan. Although the missing Mikoto Uchiha and others were later found, they remained unknown due to their power levels. When Mui saw the Three-Tomoe Sharingan, he immediately guessed that the young man in front of him was Sasuke Uchiha. Such a genius would try to assassinate the Hokage and be thrown into Hozuki Castle by Konoha Village? He didn't believe it. Recalling Sasame's instructions to him to train Sasuke Uchiha and Naruto Uzumaki, even if he were foolish, he should realize he had fallen into a trap. But this trap, he had no choice but to jump into. He couldn't win. And he still needed the Box of Ultimate Bliss to revive his son, Muku.
So, after learning Sasuke Uchiha's identity, Mui looked at Sasame. The unspoken question was, Lord, how should we proceed with the act now?
"Mui, stop him," Sasame was satisfied with his tact. At this point, it was time to give his two students another lesson. Thinking of this, he suddenly realized he had overlooked one student: Hinata Hyuga. Never mind, I'll take her out to play next time.
Mui immediately understood Sasame's meaning: stop him, not kill him. He slowly raised his right hand. But Sasuke Uchiha reacted faster. He formed hand seals and instantly opened his mouth. A large fireball, radiating intense heat and carrying a rolling wave of air, spewed forth.
"Sasuke! Leave the other guy to me!" Naruto Uzumaki shouted excitedly. Massive chakra poured out, and then countless versions of him filled the underground base. Multiple Shadow Clone Jutsu.
Ryūzetsu's heart suddenly clenched. She was about to make a move but found that this guy completely ignored her. All the shadow clones rushed towards Sasame. Each punch tore through the air. Ryūzetsu subtly retreated a step. She was in a state of distrust towards both Mui and Sasame. Naturally, she couldn't offer any assistance.
The fireball approached. Mui showed no panic. His gloved right hand ignited with red flames, instantly transforming into a sharp blade. The giant fireball was immediately sliced in half. Sasuke Uchiha's eyes narrowed, but he felt no surprise.
Thump! A figure was sent flying backward, crashing into the wall. Sasuke Uchiha subconsciously glanced over; it was Naruto Uzumaki. He was a little surprised, but he couldn't help him. Because Mui had already charged over.
Fire Release: Phoenix Sage Fire Technique! Sasuke Uchiha covered his mouth with one hand, and several fireballs, under his control, flew out. Mui burst forth with unprecedented speed, dodging all the fireballs in a few leaps in the air. The moment he stopped, shuriken exploded in front of him, like scattering flowers. Mui's expression changed slightly. He inwardly thought, As expected of the Sharingan, it can easily pinpoint his location. Since it was already too late, he didn't dodge again.
Fire Release: Great Fire Heavenly Prison! He opened his right hand, and five blood-red lines of fire immediately shot out, instantly expanding to seal all the shuriken in mid-air.
"Your time of death has come!" Sasuke Uchiha's figure suddenly appeared behind him. Numerous dazzling lightning bolts erupted from his hand, like a thousand birds chirping. The quiet underground base was instantly illuminated, appearing incredibly brilliant. Mui instinctively turned around. The Lightning Blade immediately plunged into his abdomen. Sasuke Uchiha immediately showed a triumphant smile. But the smile had not yet fully spread when it froze. Mui turned into a flash of light. It was a Shadow Clone.
Hidden Grass Style: Explosive Fist! Mui appeared beside Sasuke Uchiha. He grabbed his face and slammed him down.
Boom!
The ground cracked. Sasuke Uchiha felt as if his body was falling apart, and intense pain spread throughout him, almost causing him to faint.
Demonic Illusion: Tree Binding Jutsu! The Three-Tomoe Sharingan shook violently. The scene before Mui's eyes changed, and he was pulled into an illusory space. A giant wedge pierced through his limbs.
Genjutsu: Release! Mui quickly retreated, dodging Sasuke Uchiha's kunai. The two began a new round of battle.
On the other side, however, it was a complete rout. Naruto Uzumaki charged forward, then was sent flying back. After several repetitions, Sasame grew a little annoyed.
"Don't you have any new tricks?"
"Damn it!" Naruto Uzumaki wiped the blood from the corner of his mouth. At the same time, he communicated with Minato Namikaze and Kushina Uzumaki in his mind. In fact, the former had already recognized Sasame, or rather, recognized Sage Mode. Minato Namikaze himself had trained in Sage Mode, so he could sense the natural energy used by the mysterious masked ninja. In the entire ninja world, he could currently only think of Sasame as someone who could use Sage Mode so effortlessly.
"Kurama, it's your turn to work," Minato Namikaze said with a smile. As his words fell, a golden chakra immediately surged from Naruto Uzumaki's body. At the same time, a powerful, almost inhuman, aura erupted. Sasuke Uchiha and Mui were affected and forced to stop fighting. Both showed expressions of shock, looking at Naruto Uzumaki.
"This feeling?!" Mui's pupils constricted. Damn it! A Tailed Beast?! He could basically confirm who this mysterious masked ninja was now: the Sixth Hokage, Sasame. Are you guys playing 'ninja house' here? It was well known that Sasame had three students: Sasuke Uchiha, Naruto Uzumaki, and Hinata Hyuga. The Uchiha orphan, the Fourth Hokage's son, and the Hyuga Main House heiress. Kojiro was Sasuke Uchiha, so Musashi must be Naruto Uzumaki. The only thing that surprised Mui was that he was a jinchuriki. But upon reflection, it made sense. What's so surprising about the Hokage's student being a jinchuriki? Mui felt a surge of bitterness. Strength, indeed, allows one to do whatever they please. All his painstaking efforts over so many years were nothing compared to Sasame's sudden whim. What could he do?
"Naruto?!" Sasuke Uchiha was almost suffocated by Kurama's aura. The three tomoe in his eyes pulsed violently. An unspeakable unwillingness surged in his heart. Naruto Uzumaki had sparred with him so many times, yet had never used this golden chakra. In other words, he had always held back. This made the proud Sasuke Uchiha unbearable. He had thought the gap between him and Naruto Uzumaki was only small, but he hadn't expected it to be billions of points. His mentality had collapsed. He immediately exuded a rather gloomy aura.
Sasame glanced at him. Oh! The effect was extraordinary. His dōjutsu power surged. But he quickly shifted his gaze to Naruto Uzumaki. In the original work, Naruto Uzumaki had two modes: Nine-Tails Chakra Mode and Kurama Mode. The former was forcibly borrowing the Nine-Tails' chakra with Killer B's help. The latter was the perfect jinchuriki form where Naruto Uzumaki and Kurama achieved mutual understanding. At this moment, he should be in Nine-Tails Chakra Mode. Because it seemed a bit unstable. This was probably because he couldn't control such a vast amount of chakra.
As Sasame pondered, Naruto Uzumaki suddenly leaped up, instantly appearing before him. Without any ninjutsu, he directly threw a punch. The entire space seemed to tremble from this single punch. The so-called "miracle from great strength" was nothing compared to this. Sasame reached out and caught his fist.
"How is that possible?!" Naruto Uzumaki's face immediately showed an incredible expression. Mui and Sasuke Uchiha, who were watching, also looked as if they had seen a ghost. A punch containing such immense chakra was actually taken so lightly? This was as unbelievable as hearing Teacher Misaki announce her retirement in his previous life.
Sasame released his hand. Naruto Uzumaki immediately retreated, forming hand seals.
Multiple Shadow Clone Jutsu!Rasengan! Countless golden Rasengans flew towards Sasame.
"Idiot!" Sasuke Uchiha quickly retreated. He knew the power of the Rasengan. But throwing so many at once, this underground base would probably not survive. Mui and Ryūzetsu were also of the same opinion.
Sasame raised his hand, and shuriken flew out. Space tore, swallowing all the Rasengans.
"Teacher Sasame?" Sasuke Uchiha stopped, recognizing the Flying Thunder God Technique. He couldn't help but twitch his lips. Mui's expression hardened upon hearing this. Indeed, it's the Sixth Hokage.
"Ahhh! I can't stop!" Naruto Uzumaki, who was charging forward, slammed into the wall with a sudden brake. A huge hole immediately appeared. Fortunately, he was tough and completely unharmed. He did a carp-jump, regaining his footing.
"Teacher Sasame, what are you doing?" Naruto Uzumaki's tone was quite displeased.
"I'm training you two," Sasame removed his mask and stopped his disguise. The most confused person on the scene was Ryūzetsu. The two warring factions were actually on the same side. What confused her most was that the mysterious powerhouse was actually Hokage Sasame. But why did Mui obey his commands? Had he already betrayed the Hidden Grass Village? So what should she do now? She certainly couldn't fight. With these four people in front of her, she couldn't even defeat the weakest, Sasuke Uchiha. Let alone the others.
"Teacher Sasame," Sasuke Uchiha held resentment. He had been led on a wild goose chase, only to be told it was all a game.
"Go open the Box of Ultimate Bliss," Sasame noticed his expression and asked with a smile, "Sasuke, don't you want to make a wish?" Sasuke Uchiha was startled, his resentment turning into anticipation. He pondered for two seconds, then decided to forgive Sasame. After all, it was for his own training.
"How do I open it?" Sasuke Uchiha stepped forward, looking at the pitch-black Box of Ultimate Bliss, and asked.
"Let's move to a different location," Sasame thought for a moment. This space was too small; it wouldn't be convenient for a fight later. Without waiting for everyone's response, Sasame used the Flying Thunder God Technique to transport them to a grassland. Sasuke Uchiha and Naruto Uzumaki were already used to it and didn't think much of it. Mui and Ryūzetsu, however, felt quite desperate. With this space-time ninjutsu, they couldn't win, nor could they escape. Like meat on a chopping board, they were at his mercy. Mui could only pray that Sasame was trustworthy enough.
"Naruto," Sasame pointed to the Box of Ultimate Bliss. "Input chakra." The golden-glowing Naruto Uzumaki immediately stepped forward. Mui couldn't help but sigh. Jinchuriki really have a lot of chakra. He had spent so many years in Hozuki Castle, feeding it chakra from prisoners, yet it still couldn't reach the activation standard. Now, only Naruto Uzumaki alone was enough. Sasuke Uchiha couldn't suppress his inner excitement and moved a few steps closer.
"Mui," Sasame saw that the Box of Ultimate Bliss had finished absorbing, then separated three shadow clones and began forming hand seals. With his current strength, learning a few jutsu was easy.
