Outside Konoha Village. "So, Lord Madara has agreed to take me with him?" Shen Yu asked softly. "Yeah." Madara nodded proudly. Both Shen Yu's experiences and his Mangekyō Sharingan had struck a chord with him. They were kindred spirits in a way. Whether as a follower, an assistant, or even as an heir, Madara had decided to take him along and wander the world. "Thank you, Lord Madara." Shen Yu finally showed a heartfelt smile. "The abilities of these eyes are my greatest secret..." He raised his palm and gently stroked the area around his eye socket. His pupils were crystal - clear, exuding a jade - like texture. "But since it's Lord Madara, I might as well tell you!" Under Madara's curious gaze, Shen Yu began to speak in detail. The pupil technique of his left eye was called "Mokusara". Its ability was to adapt to all phenomena and deliver the most powerful counter - attack against the adapted target, that is, a counter - attack technique that adapted to all things in the world. Specifically, it could infinitely analyze everything he came into contact with or saw. This process was called adaptation. Once the adaptation was completed, he could nullify the effects of such influences, gain permanent immunity to damage, and launch a practical counter - attack against the source of the thing. The power of adaptation was in line with the law of cause and effect and would not be overridden due to time and space. Moreover, if he endured an attack during the adaptation period, the adaptation process would be accelerated. The so - called "infinite analysis" meant that the analysis of an already adapted attack would not stop but would only become more optimized! The only thing it couldn't adapt to was the damage to both eyes caused by consuming pupil power. And the pupil technique of his right eye was called "Ame no Shita no Futatabi". Its ability was time - space regression. He could freely reverse his own time - space state and unconditionally restore his current state to a certain state in the past. The maximum time range was 5 minutes, and the time scale tended to be infinite. There was only a 1 - second cooldown after activation. Whether it was the time state or the space state, he could select them flexibly. However, the time nodes that had already undergone the regression operation could not be selected as the target nodes for regression. The more Madara listened, the more interested he became, and his eyes sparkled with amazement. "Infinite adaptation and time - space regression, these are truly 'god - like skills'. And when the two are combined, the effect is even more extraordinary." It had to be said that the leader of the Uchiha clan had a discerning eye. Shen Yu blinked. In fact, he had hidden a little bit about the ability of his right eye. The object that could be selected for time - space regression was not limited to himself! Everything in the world, as long as it was within his sight, could be regressed in time and space! The selection of the regression object could only be specified to a macroscopic individual at most. But doing so would consume a large amount of chakra. The greater the impact of the object on the macroscopic world and the more distant the selected regression time point was, the more intense the consumption of pupil power would be. He really couldn't be blamed for being cautious with Madara. If the full ability of his right eye was known, it would mean that he was not only the strongest shield but also the strongest support! God knew if Madara would treat him as a tool. Living in this ninja world, one had to be cautious everywhere. "Alright, let's go." Madara turned around, and the previous melancholy was completely diluted by the joy of taking Shen Yu under his wing. But Shen Yu didn't move. "What's wrong?" Madara slightly turned his head and asked in confusion, "Did you leave something behind?" "Well... you could say so," Shen Yu smiled softly. "Lord Madara, there is actually one more clansman who has awakened the Mangekyō Sharingan." "What?" Madara asked in surprise and disbelief. "Could it be your younger brother?" Shen Yu shook his head. "He doesn't have that talent. He hasn't even awakened the Sharingan yet. But that's not important..." "... I wonder if Lord Madara remembers that secret weapon of the Uchiha clan that was sealed during the middle of the Warring States Period?" "The Uchiha clan's secret weapon?" Madara pondered for a moment and then suddenly realized. The dust of years fell rustlingly, and a long - forgotten past event slowly emerged in his heart. Many years ago, when Madara was not yet the clan leader, a young girl named "Uchiha Hikari" was born in the Uchiha clan. Just like Shen Yu, she had also awakened the Mangekyō Sharingan at a very young age. Her pupil technique was an amazing "Yachiho". "Yachiho" had the ability to mark the enemy, absorb the enemy's chakra to strengthen herself. Once the mark was placed, she could control the enemy's spirit and chakra through the connection, and the chakra could be transmitted to herself or others regardless of the distance. Naturally, such a skill attracted the attention of her clansmen. The power - holders in the clan regarded her as a secret weapon and imprisoned her in a dark dungeon. She was only let out when there was a need for battle. However, that was not enough. In pursuit of the ultimate power, these lunatics forcefully implanted the two pupil techniques of "Amaterasu" and "Tsukuyomi" into her body, completely turning her into a weapon of the Uchiha clan, depriving her of her name, freedom, and the right to be a "person". Thus, the Uchiha's strongest weapon - Nameless, was born. The appearance of Nameless immediately reversed the Uchiha's declining situation on the battlefield. The Senju clan, who had suffered a setback, joined forces with other ninja clans to carry out a targeted battle. Finally, at a great cost, they managed to seal Nameless. "Could it be that you want to free her?" Madara asked. "Yes, she was also abandoned. If we can get her to join us, under your leadership, Lord Clan Leader, couldn't we be a new Uchiha?" Shen Yu coaxed persuasively. "A new... Uchiha?" Madara was stunned, and a warm current surged in his heart, brightening a certain dark corner. "But..." He slightly frowned. "That was a long time ago, and even I don't know the location of the seal." "You don't know, but Konoha might know." Shen Yu showed a sly smile. "I guess there must be a secret scroll about the weapon in the secret room of the Hokage Building." Although he didn't know the exact location of the seal either, according to his memory, this information was recorded in a secret scroll called "The History of Seals in the Warring States Period", and such secret scrolls were usually stored in the secret room of Konoha. "I see..." Madara thought thoughtfully, and for a moment, he was a bit hesitant. He had just "broken up" with Hashirama and left the village not long ago. If he went back now with his tail between his legs... that wasn't his style! Shen Yu saw Madara's hesitation and immediately patted his chest. "Lord Madara, I can sneak back quietly and steal the secret scroll under the cover of night." "Isn't it a bit dangerous for you? Aren't you afraid of being discovered by the Senju's ninjas?" Madara looked towards Konoha and shook his head. Shen Yu smiled confidently. "Lord Madara, instant movement and stealth are my specialties. They won't find out. Even when I followed you out of the village, I managed to avoid everyone's sight." "No wonder you didn't come out with me immediately. So you had such a plan in mind..." Madara mused. He was a decisive person and immediately agreed to Shen Yu's plan. The two of them agreed to act tonight. Whether Shen Yu succeeded or not, he had to leave the village before the moon was at its brightest, and Madara would hide outside the village to接应 him. Then, Shen Yu's right eye emitted a red glow. As the pattern of the Mangekyō slowly rotated, fine blood vessels instantly appeared in the white of his eye. The setting sun was like blood, fire - colored clouds were floating, fallen leaves stopped in mid - air, and the sound of the wind ceased in his ears. Time seemed to stand still at this moment. From Shen Yu's perspective, his body left a strange and distorted trajectory in space, like a long noodle, stretching from here all the way to Konoha Village. His vision seemed to jump into a four - dimensional space. The progress - bar - like existence was the trajectory he left in space during the 5 - minute period. Every moment was clearly visible. Now, he could freely drag this progress bar. After selecting a time node and clicking "play", he would immediately appear at the selected position. This was his pupil technique, "Ame no Shita no Futatabi". Shen Yu dragged the progress bar to the limit, 5 minutes ago, when he was hiding in a hidden grass in the village. In the next instant, he disappeared in front of Madara. This clean - cut way of disappearing was like erasing a pencil mark with an eraser, vanishing in an instant.
