Naruto: The Savior

"The bigger the body, the greater the consumption?" Shuimu muttered to himself thoughtfully.

When I asked about this, it was not that Mizuki was particularly concerned about the progress of oil girl Shino's practice, and the study of the family's secret arts, and her parents were worried about it. What Mizuki was concerned about was the problem of too much consumption mentioned by Shino Oil Girl.

In the ninja world, there is a problem that has been ignored by everyone for a long time. Even in such an environment, Mizuki has always been attracted by other things and did not pay special attention to these problems. Although I felt something was wrong, I didn't care too much.

This problem that cannot be ignored is that due to the influence of chakra in the ninja world, the probability of biological mutation is very high, and it is not uncommon for wild animals to become violent and large. So that it is not unacceptable to give birth to some super-large creatures that are obviously beyond the range of nature. As for the terrifyingly huge intelligent creatures, they did not attract the attention of the ninjas, and they were only regarded as psychic beasts and combat partners.

It is true that the conditions in the ninja world are sufficient to give birth to these super intelligent beings. But is this really normal? Individuals of intelligent creatures and intelligent races are not the same concept. As long as Mizuki himself is willing to pay a little price, he will greatly transform his giant bear Bo Taijun, making it a giant bear that is smarter than ordinary humans. However, it is almost impossible to create a race of intelligent giant bears that can survive in nature.

The three sacred places of psychic beasts, these magical places, breed two intelligent races, giant toads and giant snakes.

The slug fairy in the Shibone Forest is too special and mysterious to mention it; in Longdi Cave, only ten thousand snakes often appear in front of people, and there is too little information there, and the specific situation is unknown; There are three brothers, Ken and Toad Hiro; and two brothers, Toad Long and Toad Ji, who are the sons of Toad Wentai; there are Immortal Zhima and Immortal Fukasaku, and the top is Toad Maru. Others include the iron-armed toad, the scroll toad, the Yansu toad, the toad loyal, the toad force, etc., obviously not individual intelligent creatures, but an intelligent race.

After thinking about this, Shuimu got up and said to Xiao Chun next to him: "I'm in a hurry to eat. I'll go and pour some water to drink. You wait for me for a while, and I'll come when I go."

After speaking, Shuimu didn't attract anyone's attention, and quietly approached the backstage.

...

In an empty lounge, Shuimu was holding a water glass thoughtfully, an identical figure walked in, and then closed the door with his backhand.

"Did you hear it too? What are your thoughts?" Shuimu asked in a trembling voice.

"As you think, I probably won't have too different opinions, as long as you can consider it."

Shuimu frowned, looked at the clone, picked up the cakes that Shuimu placed in the small bamboo basket on the table at will, and ate it. "It's really delicious!"

"If my conjecture is true, it would be too hopeless."

Shuimu avatar said while eating: "One leaf can't see Mount Tai, in fact, we should have noticed it long ago."

"Do you still remember some biological research results in previous lives? Those so-called archaeologists who dig fossils everywhere have unearthed many ancient insect fossils, and found that the size of the insects at that time was much larger than that of modern times. A A millipede the size of a matchstick might have been bigger than a snake hundreds of millions of years ago, do you know what that means?"

After thinking about it, Shuimu replied: "There are indeed many large creatures in ancient times, but most of them are the result of the influence of climate change."

"Climate?" Shuimu avatar smiled and said, "Maybe, there are glaciers melting, sea level rise, natural disaster theory, volcanic eruptions, super-large meteorites hitting the earth, etc. These are difficult to confirm. However, there is one thing that can be confirmed. What is clear is that in ancient times, the oxygen content in the air on Earth was much higher than in modern times!"

"You know what higher oxygen content means? More efficient aerobic respiration can generate more energy and support greater physical consumption, which means that the body can grow larger. Analogy to the ninja world, you have What did you find?"

"The amount of chakra, or natural energy, is constantly decreasing, which can be fatal to large organisms because the external environment that supports their normal survival has changed."

This conclusion is not difficult to draw, and the ontology can easily answer it.

"Like Toad Dragon and Toad Ji, when they were little tadpoles, they were easily summoned by Naruto Uzumaki's psychics; as they grew, the time of appearance became shorter and shorter; their father Toad Wen Tai, only when there is a fierce battle will be channeled out, and the same is true of the ten thousand snakes in Longdi Cave; Zhima immortals and Shenzuo immortals, no matter of life and death, basically will not appear; Toad immortals and snake immortals, they used to be There is a legend that they are active in the ninja world, and they will not appear in the ninja world at all now; as for the slug immortal who is too big to guess, the chakra stored in the Yin seals of Tsunade and Sakura cannot be fully communicated. Come out, why do you think they are so big if they don't need it? Are they all like living in the so-called holy places that don't want to appear in abandoned houses?"

Now that this level has been thought of, some problems cannot be avoided.

Competition and balance between wolves and sheep on the grasslands. If a wolf can run slower than the slowest sheep, he will starve to death; if a sheep can't run faster than the fastest wolf, it will probably be eaten as prey.

Such is the ecological balance maintained by nature, and the most efficient degree of "just enough" between competitors is always maintained. If the wolf ran as fast as a rocket, it would either die of exhaustion because it was too exhausting to keep up with the mutton, or it would eat up all the sheep and starve to death.

"With such a big toad, there are naturally big bugs that can feed it, as well as large snakes and water birds that eat toads, and giant eagles that eat large snakes and water birds."

"No matter how big the slug is, there will be no shortage of super-large hedgehogs or other creatures that feed on them, otherwise the ecological balance of nature will collapse because of this accident."

"But now, we can't find any trace of them in the ninja world at all. Maybe they were all killed by our ninja ancestors as prey to eat meat and become extinct!"

The avatar who was talking spread out his hands and made an exaggerated action to liven up the atmosphere, but Mizuki's body couldn't laugh at all.
