It was the first time for Hashirama Senju and Tobirama Senju to see a tree man, and they were extremely curious about the puppets created by this ninjutsu.

To be fair, although the tree man is very tall, he is not very strong.

Their movements are slow and their attack power is average, but their bodies and the clay shells on their bodies have strong defensive capabilities.

But in ninja battles, defense is not always that important. Unless it can reach the level of Lightning Release Chakra mode, it is difficult to become the key to affecting the outcome of the battle.

The tree man's defense is not enough to withstand a qualified Chunin, and he will be quickly destroyed by the attack of Ninjutsu.

But in this small Myoboku Mountain, there are as many as 500,000 tree people, which is too many.

Can there be 100,000 Chunins in the entire ninja world?

Senju Hashirama was not at all sure about this, but Senju Tobirama was very sure: "No, Konoha has 47,000 Chunins, and the other two villages combined have a little over 12,000."

They began to feel fear towards the wooden men that were everywhere in the mountains. If there wasn't someone with super-normal combat power like Hashirama, these 500,000 tree men alone would be able to defeat the entire ninja world.

Fortunately, the brothers saw Uchiha Yuu, who was standing with Miwa Masayo, staring at the captured toads and snakes and drooling.

The brothers' fear disappeared in an instant.

Senju Hashirama smiled and said, "Fortunately, this jutsu belongs to Uchiha Yuu. Fortunately, he is the least ambitious ninja in Konoha, otherwise the ninja world would be doomed."

Even the suspicious Senju Tobirama nodded with a smile, feeling in his heart: It is indeed very lucky.

After the Thousand Hands brothers felt relieved, they gathered together again and whispered to each other, studying how to use the Sea of ​​Treemen.

Senju Tobirama asked, "Brother, you are the expert in Wood Release, how come you don't know this technique?"

Senju Hashirama shook his head and said, "Tobirama, the Treeman Technique is not complicated. What is really scary is the number. I can create hundreds of thousands of Treemen with all my strength, but I don't have the ability to control them."

"You see, these tree people can work together to assist each other, but they can also handle tasks individually, and they can also change their working methods according to orders and suggestions from those toads."

"This... this is totally different from a puppet!"

Senju Tobirama was shocked and proposed an idea that might be realized: "Brother, do you think that the Tree Man Technique was developed by Uchiha You in combination with the Wood Clone Technique?"

Senju Hashirama shook his head without hesitation: "How is that possible?"

"The Wood Clone Technique is the same as the Multiple Shadow Clone Technique. You know that the number of clones that can be created with the ability to self-control is limited."

"Don't even mention hundreds of thousands of shadow clones. Even a hundred of them is not something you can handle."

Senju Tobirama frowned and asked, "Brother, how many shadow clones or wood clones can you withstand?"

Senju Hashirama was stunned for a moment, and then he calculated silently before answering: "If it is in my current state, I can create at most one thousand wooden clones."

"It can't be more."

Senju Hashirama pointed to his head and said, "Otherwise my brain will collapse."

At this point, all the possibilities that Senju Tobirama could think of were ruled out. He looked thoughtfully at the tree people that covered every hilltop of Mt. Myoboku.

After a long moment, he murmured, "Uchiha Yuu has developed an amazing technique. I really want to know the secret behind this technique."

Orochimaru had been dealing with Uchiha Yu for a longer time, and had guessed early on that Uchiha Yu had come up with something remarkable.

With the support of this magical thing, many ninjutsu can exert incredible effects, especially with decisive advantages in scale and flexibility.

So Orochimaru was not very surprised by the Tree Man Technique. His attention was focused on the colorful barrier.

After careful observation, he confirmed that the technique behind this barrier was too powerful and was beyond his ability to master.

Orochimaru gave up his research without hesitation and waited patiently for Uchiha You to finish his conversation with Shisui before asking, "Uchiha You, will Myoboku Mountain also be handed over to Konoha like Ryuchi Cave?"

Uchiha You replied: "Of course not. Konoha has managed the Ryuchi Cave for three years and was able to raise such a large group of snakes to extinction. I can't hand over Myoboku Mountain to Konoha."

Orochimaru's face turned red. As the Hokage, he was also responsible for the destruction of the snake group in the Ryuchi Cave.

Well, the responsibility is not that big. After all, he didn’t eat much of the delicious snake soup. He just consumed quite a few big snakes during his experiments.

No, no, no, that number is not much, at least it is nothing in front of the huge group of snakes.

The key to the demise of the Longdi Cave snake population is still the reproduction problem.

After the ownership of Ryuchi Cave was handed over to Konoha Village, a large number of outstanding Konoha ninjas passed rigorous assessments and entered Ryuchi Cave for training and research.

In the Ryuchi Cave, a ninja successfully developed a magic technique, opened up a new way of practicing magic techniques for Konoha Village, and made a great contribution to the balance of power between the Snake Force and the Tiger Force.

The ninjas of the Aburame clan bred a new type of parasitic insect, called the fairy insect, which was larger and more powerful, allowing the Aburame clan to achieve their goal of cultivating immortality by using the insects.

The ninjas of the Inuzuka clan have worked hard to train ninja dogs. Although a dog sage has not yet been born, the quality and strength of ninja dogs are steadily improving.

In short, the ninjas of Konoha Village do everything, but except Orochimaru, no one is interested in snakes, so they can only maintain the survival of the snake group through missions.

Because there was no ninja paying attention to the living environment of the snakes, when the ecological crisis occurred in the Ryuchi Cave, it was ignored.

The initial changes were small, just the disappearance of the annoying cockroaches that were everywhere.

Perhaps an unintentional experiment by a ninja triggered a certain link in the ecosystem of Ryuchi Cave, leading to the extinction of the extremely tenacious cockroaches.

With the extinction of cockroaches, the number of mice, which had lost their important food source, was greatly reduced, and they quickly became extinct due to the hunting of snakes.

After the rats became extinct, it was the turn of the common snakes in the snake group to suffer. Hunger and hunting by big snakes quickly destroyed the common snake population.

When all the ordinary snakes died, the huge ecological disaster was finally discovered by the Konoha ninja, but it was too late.

Those big snakes and giant snakes, which are rich in natural energy and extremely valuable, lost their food and could only rely on the blood fed by the Konoha ninjas to survive.

For some unknown reason, after the common snake population became extinct, these remaining large snakes did not lose their ability to reproduce and did not lay a single snake egg for two consecutive years.

Not only did it not lay eggs, the giant snake also showed inexplicable symptoms of weakness, and no matter how much meat it ate, it could not curb the trend of weakening.

In the end, the giant snakes lost their appetite one after another, and they survived only by relying on the energy stored in their huge bodies.

In the 50th year of Konoha, the last giant snake died of starvation, and there was no longer a snake in the Ryuchi Cave.

Uchiha You lost the long-awaited resources of the Ryuchi Cave, and Orochimaru lost his last summoning beast.

Yes, Chiya, who chose to surrender, also died of systemic organ failure caused by hunger due to uncontrollable loss of appetite.

This is a painful lesson.

Now that Mount Myōboku has been captured, a large number of toads and snakes have been trapped in the barrier on Mount Myōboku and have become captives and spoils of the Flower-Fruit Mountain.

Uchiha You looked at the toads and snakes filling the pits and valleys, and his desire naturally rekindled in his heart.

The hope of raising spiritual creatures.

This is a unique racial instinct of the Yanhuang race, just like seeing fertile land and wanting to plant something, or seeing a straight stick and wanting to play with it.

Even after hearing Uchiha You's explanation, Uchiha Shisui and Uchiha Ayumi still found it difficult to understand.

This was caused by the different values ​​of the two sides. Although the two younger brothers had made great achievements in cultivating immortals and entered the Huaguoshan sequence, they were ultimately from the ninja world, which was very different from the head of their own family.

It was different for Miwa Masayo who was standing next to Uchiha Yu. She understood from the beginning what her partner wanted to eat, delicious snake soup, dry-pot toad and braised snake segments.

Well, the kitten with tears streaming down his face also wants to eat. If he wants to eat, he has to catch them. If he catches enough, he has to find a way to breed them. Isn’t this natural?

The toads of Myoboku Mountain and the snakes of Ryuchi Cave are high-level species that have been bred in the two holy places for thousands of years. The natural energy contained in their bodies is second only to the transparent fish in the underground river.

The key is that the number is so large that as long as they are well raised, they can definitely meet Huaguoshan's demand for meat.

With the failed experience of raising the animals in the Ryuchi Cave, Uchiha You had to consider the issue from a long-term perspective in order to satisfy his own appetite.

For this reason, he spared those toads and snakes that had lost all their fighting spirit and had become intelligent. They could serve as administrators of Myoboku Mountain and directly manage those toads and snakes that were still animals.

As long as there is a layer of guiding snakes and toads between them, the little toads and snakes should not feel strong fear, and it will not affect their impulse to eat and shiver. They can eat well, grow meat and have children.

It just so happens that one of Uchiha Yuu's principles is that he will never eat creatures that have awakened intelligence.

Because wisdom is a miracle in the universe, it must always be treated like a human being and must be given the most basic respect.

Intelligent life can be treated as a friend or a stranger. Even if it unfortunately becomes an enemy, it can be killed, but it is absolutely not allowed to be eaten.

Even if it were the small frogs and snakes that he farmed, as long as they were lucky enough to awaken their wisdom, Uchiha You would never eat them.

They will have three paths to choose from: those with flexible ideas can join the Myoboku Mountain management team, those who are brave and fearless can die heroically in battle, and those with strong wills can use their own abilities to find a gap in Myoboku Mountain and escape.

The gap is ready, as long as they look for it carefully, they will be able to find it. Uchiha You will definitely not stop them.

As long as they can escape, Uchiha You will arrange people to guide them so that these most talented toads and snakes can find the resistance group led by the immortal as soon as possible and obtain a safe environment for growth.

In Uchiha You's opinion, captive animals are always more fragile than wild ones.

This does not mean that captive individuals are weak, but from a racial perspective, wild animals are more resilient to risks and will not be easily wiped out by a disease.

Just like those white and tender fat pigs in the pig farm, they can usually easily crush those black wild boars, even if the wild boars have long fangs.

After all, domestic pigs that are well fed and not cold will definitely be fatter than wild boars that eat wind and drink dew. The fat ones are stronger than the thin ones, which is a basic rule among animals.

However, the fat pigs in the pig farms are all sick. Even with the protection of antibiotics, they may still be killed from time to time.

The farm-like Myobokuyama is similar to a pig farm. Toads and snakes can definitely eat well, but they cannot grow freely.

They must comply with the meat requirements of Huaguo Mountain.

This means that the future of toads and snakes will be artificial screening and concentration into only a few types, such as those with the largest meat output, the most natural energy, or even those with the best meat taste.

The worst thing is that this type of strengthening will inevitably cause toads and snakes to become weak and vulnerable, and easily attacked by plagues and diseases.

Moreover, excessive genetic homogeneity will pose a greater risk, just like the Gros Michel banana on Blue Planet, which is large, thick-skinned, sweet and mellow, and is the undisputed king of bananas.

But all Gross Michel bananas grown around the world are reproduced asexually. From a genetic point of view, billions of Gross Michel bananas are actually a grass.

As Fusarium oxysporum mutated and became able to infect Big Mac, this banana variety, which was grown all over the blue planet and had billions of clones, became extinct in just a few years.

If there were no wild bananas, humans would not be able to eat bananas.

This is also the reason why ginkgo trees, which are planted everywhere in China, are still first-class protected plants and are listed as critically endangered species.

Because all the ginkgo trees in China are genetically one tree. If one tree is knocked down by some mutated fungus, it means the countdown to the extinction of all the ginkgo trees will begin.

Therefore, protecting the toads that survive in the wild is an essential redundancy for the captive toads and snakes in Myōbokuyama.

Therefore, the sudden attack launched by Mount Huaguo successfully destroyed Mount Myoboku. The Great Toad Immortal and the White Snake Immortal were killed, but the two relatively weaker immortals, Shima Immortal and Ichikijima Princess, escaped.

There is still a wish in Uchiha You's heart:

Ten years after Hashirama Senju went to Konoha, the unified ninja regime that was born was able to unify the hearts of the people, thanks to the ten-year natural disaster caused by the battle between the three Six Paths-level powerhouses.

So does the unification of this time and space, which has not yet been completed, also require a real "enemy"?

Can the Snake Clan led by Princess Ichikishima and the Toad Clan led by Sennin Fukasaku grow up in the future and take on the historical responsibility of tempering Konoha?

He sighed. The future of Konoha had nothing to do with him.

Uchiha You has made up his mind. When the situation in Myoboku Mountain becomes unstable, he will travel back a thousand years to that ancient mythological era.

Through the information brought back by the [System], he has grasped the reason why Hashirama Senju stayed for a long time, and has made preparations to stay for a thousand years at a time.

He will be stranded from a thousand years ago to the present era in one breath, and after fully mastering the power of the Bloodline Network, he will find a way to return to the current time and space.

Or... never come back.

Uchiha Yuu set up the Flying Thunder God Formation on the spot, and by transferring the Flying Thunder God Mark in the Sharingan, he summoned Uchiha Shisui and Uchiha Ayumi over, and then handed over most of the work on Mount Myōboku to them.

The next six people who came to raid worked together, led by Uzumaki Mito, to dismantle and rebuild the colorful barrier into a large barrier that combined invisibility and defense.

With technology provided by Uchiha Yuu, the defense method was changed from arch force confrontation to a space-time maze combining space folding and penetration.

This means that touching the barrier from any angle will not cause any confrontation, but will only cause the person touching the barrier to pass directly through the barrier and reach the other side of the barrier's diagonal.

Because of the effect of space folding, the person who crosses the barrier will not even realize that he has experienced teleportation. All his senses will tell him that he just took a normal step forward.

The Second Hokage, Tobirama Senju, who was proficient in the Flying Thunder God Technique, was unable to detect this kind of spatial travel.

Uzumaki Mito, who led everyone to build this barrier, could only rely on his knowledge of the existence of a barrier here and use the seal-lifting technique to align with the coordinates to discover the hidden barrier.

Among all the people, only Uchiha Yu, who had developed the ability to sense space through constant time travel, was able to discover that the space here was folded.

Uzumaki Mito exclaimed: "This barrier is really amazing. It turns out that barriers can be developed in this direction. This is great."

Senju Tobirama has secretly decided that while he will continue to study the dragon veins, he will also restart the development of the Flying Thunder God Technique. This kind of space barrier is so interesting.

Orochimaru even made a request openly: "Second Hokage, let's work together to study the space technique."

Senju Tobirama agreed without hesitation: "No problem."

The space technology developed by Uchiha Yu is too advanced, far beyond the development of the Flying Thunder God Technique, and requires careful research to get to the bottom of it.

Senju Tobirama felt his scalp tingling just thinking about it. Orochimaru must have felt the same way, which is why he was so eager to propose joint research.

Uchiha You didn't care at all about the connection between them.

He simply asked Orochimaru, confirmed that he was willing to give up everything and live in seclusion in Huaguo Mountain for a long time, and promised not to disclose the secrets of Huaguo Mountain to the outside world, and then gave Orochimaru the method of entering and exiting Huaguo Mountain.

Uchiha You also allocated a piece of land to Orochimaru and asked him to dig a hole at the foot of Mount Nakagami where he lived, to use as a place to live and study.

Three months later, Uchiha You suddenly brought Uchiha Shisui back to Konoha Village and urgently summoned the core members of the Uchiha clan.

The Uchiha clan gradually dispersed as Konoha became stronger. It took two full days to gather three Mangekyo, 82 three-magatama jonin, and 655 members of the Tiger Corps.

When 740 Uchiha gathered at the Nanga Shrine, it seemed that the shrine could not keep up with the development of the Uchiha. The huge hall was not enough to accommodate the three-magatama jonin.

In desperation, the Uchiha could only hold the meeting in the courtyard.

Uchiha Yu first asked Uchiha Shisui to show his Mangekyō Sharingan, and then announced amid the surprised cheers of the Uchiha:

"From today on, Uchiha Shisui will take over from me as the head of the Uchiha clan."

Uchiha You opened his Mangekyō Sharingan, scanned the 740 Uchiha ninjas present, and issued a final question: "This is my last order as the clan leader..."

“Who’s for and who’s against?”
