Benefits

Sasuke was a person waiting for an opportunity to strike, wasn't he? Was he willing to give up his body to Orochimaru so easily? No, he wouldn't. Even three years ago, when he went to find Orochimaru and said he would exchange his body for power, he never intended to give Orochimaru his own body. He fully utilized the power of the white-eyed wolf, inherited from his bloodline. When he became strong enough, he would take down Orochimaru.

He had this plan from the beginning. Otherwise, he wouldn't have left before and come to find Orochimaru. He wanted Orochimaru to use the Reincarnation Jutsu on him, and then he would counterattack and take Orochimaru's power. Unfortunately, things didn't go as he planned. Sasuke was too confident and underestimated the current Orochimaru, and he ended up facing difficulties.

However, even in this situation, he was not just waiting to be killed. He was not really going to give his body to Orochimaru after killing Itachi. He had his own ambitions, to revive the Uchiha clan. He couldn't die before accomplishing that.

His current words were just to keep Orochimaru in check. Being intelligent, he knew that Orochimaru intended to sit back and watch the battle between him and Itachi, waiting for an opportunity to benefit from it. But he had no choice, Sasuke had to do it. Although it was riskier, there were opportunities within the danger, and Sasuke was aware of that.

He remembered something Itachi told him about the Mangekyo Sharingan and how one had to kill their closest person to obtain it. Despite not wanting to admit it, Sasuke knew deep inside that besides the intense hatred he felt for Itachi, there were also deep feelings of affection and reluctance towards his older brother from their childhood.

With these complex emotions, if he killed Itachi, not only would he avenge the Uchiha clan, but he could also unlock the Mangekyo Sharingan. With that, even if he suffered injuries after the battle, he could temporarily suppress Orochimaru and, once recovered, completely destroy Orochimaru with the power of the Mangekyo Sharingan.

Sasuke wasn't a fool, on the contrary, he was very clever. He knew he was at a critical point of life and death, and so he exploded with determination. He had no way out, so he could only seek prosperity amid danger. But unfortunately, although his thoughts were correct, they were not enough, as there was still one thing lacking.

Itachi had to give his Mangekyo Sharingan powers to Sasuke. Only then, with the extreme clash of these two complex and extreme emotions, along with Itachi's Mangekyo Sharingan power, could Sasuke unlock the Mangekyo Sharingan. It was not because Sasuke's talent was really that poor; it was just that his heart had fallen too deeply into corruption. How could he control the Mangekyo Sharingan and unlock it himself? It was already fortunate that he didn't become a slave to the Mangekyo Sharingan after unlocking it. Therefore, he couldn't unlock it by himself.

Fortunately, he had a good older brother. His decision to seek prosperity amid danger was the most correct decision he had made in his life. Perhaps with his all-out effort and his brother's sacrifice, he had a chance to turn the tables. Of course, everything still depended on his own destiny.

"It's too unbelievable. Could this be the legendary dual cultivation?" The next day, Ryoha woke up. The most shocking thing was that he immediately noticed the changes in his body after waking up. He found that his life force chakra had undergone some kind of transformation last night, becoming even more pure and powerful. So, he immediately activated the Sharingan to examine Tsunade's chakra and discovered that her life force chakra had also become more refined compared to yesterday, as if it had been purified.

This discovery immediately astonished Ryoha, and he opened his mouth wide in surprise. After all, this was a benefit that only cultivators or martial artists (experts in internal energy) could enjoy in novels. Could it be that he also had this benefit? Then why didn't he sense it before? Or was it only when he and Tsunade engaged in this intimate act that such a situation occurred?

Thinking about it, Ryoha roughly understood. It wasn't because of his innate talent; it was entirely because both he and Tsunade possessed the body of a Sage, and they both mastered the transcendent Wood Release. They represented yin and yang as a male and a female. Last night was Tsunade's first night, and with their union, the blending of the male and female Sage bodies, and the mutual fusion of their life force chakras, they seemed to complement each other like yin and yang.

In one night, not only did their bodies and spirits experience great satisfaction, but their life force Chakras also experienced tremendous fulfillment. They seemed to draw what they needed from each other's life force Chakra, and after this exchange and fusion, both Chakras became even stronger.

"Why are you awake so early?" Ryoha's slight movements immediately woke up Tsunade.

"Tsunade, quickly feel the chakra inside your body," Ryoha immediately said to her. Seeing Ryoha's joyful expression, Tsunade also lost her sleepiness. She closed her eyes and felt it. Then she opened her eyes wide with disbelief. It was essential to know that the amount of chakra could be easily increased using various secret techniques or external methods, such as becoming a Jinchuriki or undergoing body modifications or absorbing external chakra.

However, the purity of chakra could only be enhanced through improvement in strength and realm. Only when both the body and spirit continuously became stronger and then constantly extracted chakra would it become more refined. In other words, it was only when overall strength improved that chakra's purity could increase. This was why the gap between Elite Jonin and Kage was so significant.

A regular ninjutsu in the hands of a Kage-level expert would have far greater power than in the hands of an Elite Jonin. Besides the difference in their ninjutsu mastery, the other factor was the purity and refinement of the Kage-level expert's chakra. Tsunade and Ryoha possessed the strongest chakra in the ninja world, and even refining and purifying their life force chakra was increasingly difficult.

They rarely encountered situations where their chakra was insufficient during battles because their chakra reserves were enormous. But to experience such a significant improvement in the quality and quantity of their chakra in just one night was truly unbelievable. Even Tsunade, who was extremely knowledgeable, couldn't figure it out in an instant.
