If you look at the history of the ninja world in detail, you can find that although the strength of the entire world is on a steady upward trend, there is an obvious fault line in the high-end combat power.

In the original mythical era, it was still the era when samurai and onmyoji were prevalent, and the world's highest-end strength was only the current elite upper ninja level. Later, if it hadn't been for the will of the world to save itself, let her give birth to the "twins of fate" - Otsuki Yufu and Otsuki Feather Village, and instead sealed it, the world would have been destroyed by her. But the two brothers also relied on the joint efforts of the two to defeat their mother, and the two of them failed to reach the immortal realm of Kaguya Ji in their lifetimes, and their strength was reduced to a level.

At the end of the Mythological Age, the Six Dao Immortals also subdued the world by themselves, and they founded the Ninja Sect and passed down the Chakra cultivation method, which enhanced the overall power of the world. Slowly the Ninja Path arose, knocking out the Samurai and Onmyoji Paths. However, his successor, the second-generation descendant of the Ninja Sect, is also his two sons, Indra and Asura, although the strength of the two is far beyond that of others in the ninja world, but compared to the six immortal brothers, the strength is undoubtedly another level, and it can only be regarded as the first entry into the six realms.

After Indra and Asura, although the third generation of the ninja sect is also a strong man, there is no gap between heaven and earth compared with other people in the ninja world, and there is no longer the power to suppress the entire world, and the ninja sect has been extinct for three generations.

After that, the Warring States period began, and various countries, families, and organizations fought each other. Because of the continuous wars, the population base has not grown fast, not only the overall strength of the ninja world has not advanced but retreated, and the high-end combat power is not as strong as the shorter but very stable ninja era, and the first entry into the shadow level is extremely strong in that era.

Until the end of the Warring States Period, there were two unconventional "ninja gods" of Senju Pillar and Uchiha Madara, a wooden escape blood inheritance limit, and an eternal kaleidoscope writing wheel eye, which was the strongest chakra reincarnation after Indra and Asura himself. The two worked together to end the Warring States period and created a model of one country and one village, which is a new pattern in the ninja world that continues to this day.

However, after the two of them, although they have also experienced three ninja wars, because the frequency of wars has decreased, the population base has increased more than that of the Warring States period, and the overall strength of the ninja world has increased a lot. In terms of high-end combat power, there are not only many film-level powerhouses, but also many film-level powerhouses at the peak and even super-shadow.

However, there has never been a person who has pushed the world across the world like Senju Tsuruma and Madara Uchiha, and can be called the "God of Ninja".

"Considering the history of the ninja world, we can draw a conclusion-" Li Shuimuying's clone said slowly, "The will of the world favors the improvement of the overall strength of the ninja world, but I don't want to surpass others too much in high-end combat power, and the 'demigod level' that has just entered the super shadow is the limit!" Therefore, every powerful blood inheritance limit is either difficult to awaken, or the advanced conditions are harsh, even if it is lucky to be promoted to a very high stage, there is still the possibility of 'blood inheritance disease' in the future, which can be regarded as blocking most of the blood inheritance ninja world under the peak of the shadow level. Like Nagato, a 'god' who is powerful but can't continue to use his power can only be regarded as a pseudo-ninja god. ”

"And for ordinary ninjas, like the three generations, it is already the limit to develop all seven chakra attributes, and it is not easy to reach the 'demigod' at the peak, and it is not easy to maintain the shadow-level realm when the old man's physique declines." Li Shuimu added, "And the 'Immortal Mode' that uses natural energy can be regarded as an additional path to promotion for ordinary ninjas, but the cultivation conditions are harsh, and the cultivation process is also very difficult, and there are very few people who can successfully cultivate." ”

"This is also very understandable, after all, natural energy is the origin of this world, and those who can skillfully control the immortal chakra have a certain amount of world authority!" Li Shuimuying's clone shrugged his shoulders and said, "If you can develop the 'Immortal Mode' to the extreme, you can also advance to the Six Dao Realm, so the will of the world will inevitably have a limit. Even if the 'Immortal Mode' is successfully cultivated, it will be slowly influenced and brainwashed by natural energy, and he will become a 'good person' who will work hard for the ninja world wholeheartedly! This is also the case since the beginning, and this is true between the first generation of Thousand Hands Pillars, and if you are eroded by natural energy without awakening in the future, I am afraid it will be the same! ”

"That's why you, under the influence of natural energy, gave Jiraiya a drop of heart blood, which not only weakened yourself for a while, but also improved Jiraiya. Come to think of it, Jiraiya broke through and refined the thunder attribute chakra when he was fighting against you, and became a person with a full attribute chakra, plus a short period of large overall improvement when using the 'Immortal Mode'...... In the future, I'm afraid that the ninja world will have the power to limit you. ”

"Damn, that's a bad feeling!" Li Shuimu scolded secretly.

"Of course, in fact, you don't have to worry too much, after all, Kaguya-hime, who will be revived in the future, is the first target of the ninja world's will, so it will give birth to the two new 'children of destiny' Naruto Uzumaki and Sasuke Uchiha." Li Shuimuying's clone comforted him, "And you can be regarded as accidentally causing trouble this time, just pay more attention in the future." ”

"I'm afraid it's not that simple!" Li Shuimu is not so optimistic, "The change in thinking is the most difficult to notice, and I only reacted when you reminded me this time." I wonder if this will happen in the future?! ”

"Huh? Are you worried that the changes that natural energy influences your mind will be permanent? Li Shuimuying's clone frowned, "Probably not." ”

"It's hard to say!" Li Shuimu said solemnly, "There is one thing that I haven't figured out before, but now it's a bit eyebrow-raising." That's why Orochimaru doesn't have Immortal Mode, but his heir, Medicine Master, does? Could it be that with the qualifications of the Great Snake Pill, he would not be able to refine the immortal mode? I don't believe it! ”

"You doubt ......"

"Now that I think about Orochimaru's almost broken soul state, I'm afraid it can't be caused by two 'immortal reincarnations'!" Li Shuimu squinted his eyes and said, "And the spell seal technique he developed, now that I think about it, it's really a genius design!" Deliberately use the spell mark to absorb natural energy and provide the host with the power of the spell seal of the pseudo-immortal mode! The sigil is a sieve that removes some of the natural energies that he thinks are bad. Of course, if it weren't for Orochimaru adding his own spiritual will to it, it would have been a good thing. And looking at it this way, I am afraid that the erosion of natural energy on the mind is much more serious than we think! ”

"You mean, natural energy actually erodes the soul?! And Orochimaru discovered this, and even did not hesitate to cut off a part of his soul in order to achieve the 'purity' of his soul? Li Shuimuying's clone widened his eyes and said, "It's crazy!" ”

"Scientists, they're not much different from madmen." Li Shuimu sighed, "People who can ruthlessly do things to their souls and bodies, I really admire them when you think about it!" ”

"And what are you going to do now?" Li Shuimuying asked, turning his head right to look out the window, "It's about to dawn, and the three of them are about to wake up, so you might as well think of a way later." ”

Li Shuimu thought for a moment and asked, "How long can you last with chakra?" ”

"There's still some left, if you don't fight, you should be able to last a day, what's wrong?" Li Shuimuying said suspiciously.

Li Shuimu didn't speak, he took a step forward, and put his right hand on the shoulder of the shadow clone.

Li Shuimuying's doppelganger's face changed, as he felt a huge chakra from Li Shuimu's hand injected into his body.

With Li Shuimu's ninjutsu attainments, the shadow clone's technique could have long been arbitrarily arranged to create the amount of chakra of the shadow clone, and in order to prevent accidents, the chakra left in the shadow clone's body was only enough for it to exist for a day.

And at this time, the shadow clone felt that with this chakra, if he didn't fight, it would be enough for it to exist for a month!

"What are you?"

"There is no doubt that my current thinking has been affected, although I don't know whether it is temporary or permanent, but we also have to plan for a rainy day!" Li Shuimu said in a deep voice, "You were created by me before my thoughts were affected, and I need you to be there all the time, to remind me when I show something abnormal." Possibly, you will be a glimmer of life for me in the future! ”

"I'll go!" Li Shuimu's shadow clone rolled his eyes, "Do you think it's appropriate to put such a big burden on your shadow clone?" ”

"You're me, what's wrong?" Li Shuimu also rolled his eyes, "The ancients said that 'if you use people as a mirror, you can see the gains and losses', and your code name will be 'mirror' in the future." ”

"Don't! This code name immediately reminded me of that unlucky ghost in the Uchiha Mirror. Li Shuimuying's clone shook his head, "It's better to call it 'round mirror', and see your own round mirror." ”

"Whatever you like...... Li Shuimu turned his head to look at the three people on the bed, "They should wake up soon, you can go to live in the storage ring in the future, we will exchange memories from time to time, if you feel that the chakra is not fast enough, contact me immediately." ”

"yes, got it." Yuan Jing replied, and then he returned the storage ring to Li Shuimu, and he received it inside.

Although the storage ring cannot store living things, the shadow clone is not considered a real life, so it can "survive" in the ring space.

After arranging the shadow clone round mirror, Li Shuimu lay on the empty bed on the side, looking back on what happened this night, and couldn't help sighing: "I don't know if it's a blessing or a curse!" ”
