Naruto: The Savior

The harm caused by out-of-control biotechnology far exceeds natural disasters and species invasion.

Especially when artificially induced mutations can exert influence through food chain conduction, the entire ecosystem will be forcibly pulled into an extremely unstable state.

Of course, with the passage of time, natural selection and the jungle law of the survival of the fittest will come into play, and the many mutant species produced by the biological explosion will re-form a new balance and crowd out the living space of new creatures.

By that time, the drastic changes in the ecosystem will also subside, but I don't know how long it will take to adjust. Mizuki is not a professional biologist, and the level of scientific research is just that, but he has achieved many achievements through the knowledge far beyond the ninja world and the convenience of Chakra.

A few years ago, it was not so serious. It was enough to let some acquaintances clean it up when they had time, and there was not much disturbance, but now, it seems to be a bit beyond expectations.

Even if Mizuki took action himself, there is no guarantee that there will be no fish that slip through the net, such as mosquitoes, mice, and bedbugs. It is not difficult to eliminate them temporarily, and it is almost impossible to completely eradicate them.

Up to now, Mizuki doesn't know how far the influence of these things has spread. He can only see one outbreak and suppress one. He doesn't want to completely eliminate it. He can only hope to buy time and let nature Weili, the passage of time to adjust.

Fortunately, there are creatures like ninjas in the ninja world, just a few mutated creatures, and they can't make much waves.

...

The adventure journey of Yuhuo and the three little girls continued. At noon, the four of them found a shaded place to have lunch, and then rested for a while before continuing to work.

In the autumn afternoon, it was also a bit hot. Miyuki, Nagi Tsukiko and Makoto Futaba took off their shoes, rolled up their trouser legs, cut off clusters of kudzu vines in the mud and sand by the river, rolled them up, piled them up, and waited. Sister Yuhuo handles it.

After cleaning up the jellyfish in the nearby lighthouse, there is no need to worry about being stung and injured. The little ones play in the water from time to time when they are busy.

"It's nice to be young."

The fisherman who just came out of the river came over carrying a strange big fish. There were two strange long whiskers on the top of the fish's head, sharp blade-like fins on both sides of the fish, and several long whiskers on the back. Bone spurs, the most frightening thing is that a gloomy human face can be vaguely seen inside the open fish mouth.

"Wow, what is this thing?"

The fishing fire threw the big fish ashore, but the huge monster remained motionless, as if it was already dead.

The three little girls stepped forward boldly, and Xiao Meixing slashed twice with the long sword, making the crisp sound of gold and iron colliding.

"It's so hard that it can't be hurt without any effort."

In fact, if it weren't for Mizuki's carefully crafted long sword, which was as sharp as the Kusanagi sword, it wouldn't be able to cut through the outer defense.

"This kind of fish was not so big before, only the size of a fist. It hides in the mud near the shallow water, ambush and hunts small fish and shrimps for a living. The bone spurs on its back are poisonous. Many fishermen and children who live by the river step on it accidentally. When it is injured, the toxin will cause severe pain, and it will take ten and a half months to heal."

"Then why did it grow so big?"

Yuhuo shook his head,

"Looking at its scales, it should only have a lifespan of two years. It is a young fish..."

Futaba, who was quite interested, raised the fish's mouth with kunai, and looked at the unbelievably thick tongue and the tongue lines that resembled a human face.

"It's really scary. If you see it at night, you will definitely take it as a fish monster."

"Then we should find the right owner? Do you want to cut off something as evidence?"

Moonlight Nagi was also a little happy. After working for a long time, she finally gained something.

Yuhuo nodded,

"This kind of fish meat is unpalatable and useless. It will be fine after a while. You can cut off the bone spurs and fins on the back and take it back to play with slowly."

"Then... we will not be polite."

The whole fish is nearly twice as long as an adult, its side fins are about the size of a cattail fan, and the bony spurs on its back are like enlarged ice picks. It took the three little girls a lot of effort to cut them all off and clean them. And the gray-black bone spurs exude a metallic brilliance in the sun.

"Come here today, you should go back too."

"That's right, after walking so far, I'm almost late for dinner."

"Thank you sister Yuhuo, otherwise I wouldn't have found the fish monster."

"However, Sister Yuhuo's ninjutsu is so powerful, such a monster can be easily captured, even underwater."

"My hometown is in the country of the sea. It is surrounded by the sea, and the water quality is very normal. That's all I can do."

"Sister Yuhuo must have often played in the sea with her friends when she was a child, that's why she is so powerful?"

"What's the matter, I envy you too."

When I was very young, I was treated as a test subject, and all my companions died. Later, I was dismissed as a monster, and the ignorant children were also driven away with stones. The memories of that time are all bitter.

Fortunately, I am living a good life now. Although I have suffered a bit, I will no longer be regarded as a monster.

"Then let's go, sister Yuhuo, goodbye."

The three little guys collected the spoils and went home happily.

"Well, let's go."

Looking at the leaving figure, Yuhuo slowly waved goodbye.

It wasn't until the three little girls were completely out of sight that a figure suddenly appeared.

"You are really patient, playing with the children."

Yuhuo turned around, smiled lightly and said:

"It doesn't matter, it won't delay the matter anyway. You finished it? Yukimura..."

"It's over long ago."

After several years of experience, Yukimura's face became less childish and more cheerful.

Unlike the stern Uchiha Sasuke, there was a smile on his slightly sunny face, the short hair long with his little finger was a bit scattered but not messy, he held a peaked cap in his right hand, and held a long-handled sickle-shaped weapon on his shoulder in his left hand. Strong sleeves.

If it weren't for the elegant and calm demeanor that couldn't be concealed, others would only regard him as a kid from a nearby farm family who came out to play.

Yukimura put on the peaked cap, waved his right hand, a ball of flames enveloped the body of the fish monster, and burned it to ashes after a while.

"It's done, pack up and go back. I'm really tired, but it's also quite interesting. I didn't expect to have something to do soon after I came back, so I won't be bored."

"I said I want to see all over the ninja world. After so many years, haven't I seen enough?"

"It's almost there. Next time, I'll ask Mizuki if there are any good places."

"How long are you going to stay this time?"

"Some things have been delayed for a long time, and it's time to solve them..."

That guy with the same appearance, I really look forward to his expression when he sees me, it should be very interesting...
