In this era when the human pillar force system was not yet developed, all the tailed beasts in this world were almost in a wild state. Except, of course, a tanuki that has been sealed in a kettle by the world.

As for the capture of Tailed Beasts, the biggest difficulty for Pillar and Madara is not to defeat the Tailed Beasts and recover them, but to find the Tailed Beasts that live in inaccessible locations. Although, with the help of money, they can buy information about tailed beasts. However, even so, it took them a whole year to find the information of the nine-tailed beasts. After that, after only half a year of operation, they got all the tailed beasts except for the one that guarded the crane.

Of course, when Tsuruma and Madara caught the tailed beast, the ninja villages of the other four major countries did not sit idly by. After all, in the quest for power, no ninja will give up the slightest opportunity.

Among them, the ninja village of the water country has an eye on the three-tailed isofu and the six rhinoceros dogs in their own country. And the country of thunder is a little greedy, not only do they have to attack the two tails and eight tails, but they also cross the border of the country of fire and make up their minds against the nine tails.

Then, after this nine-tailed capture battle, a pair of two brothers named Golden Horn and Silver Horn completely became famous. Among them, the two brothers claimed to be descendants of the Six Dao Immortals, and controlled the spirit weapons of the Six Dao Immortals. As a result, the world gave them the title of "two rays of light in the clouds". Then, because he ran into the stomach of the Nine-Tails, he devoured the flesh and blood of the Nine-Tails, who was the embodiment of evil thoughts in the eyes of the world. Then, they were also given the title of "the most vicious criminals in history".

Of course, for ninjas, the title "worst" is a compliment. After all, ninja is a profession that uses violence, and a strong title is the greatest compliment for a ninja.

After that, in addition to these two countries, the land country set its sights on the four tails and five tails in its own country. At the same time, relying on the information handed down in the early years, the Shinobi Village of the Land of the Wind obtained the kettle sealed with the Morizuru.

Of course, not only the ninja villages of the big countries have taken action, but also the ninja villages of the middle (medium) countries are not to be outdone. Among them, Takino Country, which established its own ninja village, began to attack the Seven Tails in the Hundred Poison Forest in its own country.

At this point, the nine tailed beasts in the world have been shattered from their previous peaceful lives, and they have all been harassed by humans one by one. That's right! It's harassment, and for a life like the Tailed Beast that is created by the Chakra of the four nature changes, the regular-level ninjutsu basically has no effect.

And the physical skills naturally need not be said much, the huge body of the 100-meter level is just standing there, like a small mountain. And, because of the sheer size of the chakra, their illusions couldn't do anything.

As a result, after Tsuruma and Madara hyped up the news of the capture of the Tailed Beast, these ninja villages who heard the wind failed in the operation to capture the Tailed Beast. It can be said that the failure was a complete failure. Except for the Ninja Village of the Land of the Wind that has obtained the Sealed Crane Kettle, none of the Ninja Villages can defeat the Tailed Beast.

Then, after all the ninja villages failed to capture the Tailed Beast, Tsuruma and Madara began to attack the Tailed Beast. So, that is, the half-year effort mentioned earlier, the two of them completed the capture of all the tailed beasts except for one.

Among them, because they didn't control their own intelligence when they captured the tailed beast, the rest of the ninja villages can be said to have a clear understanding of the gap between ninjas and ninjas regarding the actions of the two.

In their eyes, the tailed beast beating them is a father beating a son, but for Pillar and Madara, the tailed beast is nothing more than that, it is also a father beating a son. Therefore, in the face of the behavior of these two people to capture tailed beasts across borders, they are like grandsons, and they don't see anything at all.

The outside world is all about the world. But on this side of the world, it is calm.

The world with a stable intelligence network naturally knows everything about the ninja villages outside and the movements that are happening between the pillars and Madara. However, because the progress of the research is at a critical juncture, the world does not want to get involved in the Tailed Beast matter. After all, the power of the tailed beast is what it is for her!

Because the system of the islanders of Tuanfan Island is becoming more and more perfect, the world is gradually paying less attention to them. Then, as most of the energy began to be devoted to the study of intercolumnar cells, a year and a half of time was really made by the world.

The first direction of research, Chakra Replacement Seal Structure, is the world's name for this type of sealing technique. Among them, the reason why it is named structure is because the result itself is not a complete sealing technique. It is a type of structure in the sealing technique, and its function, as its name, is that it can be exchanged for chakras. Of course, this result is still very rough, and the proportion of chakra replacement is very tricky, and it is replaced by me in a ratio of ten to one. Therefore, the current world is improving the structure of sealing.

Then, there is the second direction of research. Previously, the world's plan was to obtain its chakra by eating intercolumnar cells. However, in the face of the psychological barrier of cannibalism, the world is not ready to use the writing wheel eye to hypnotize itself. So, the world began to find a different way, she extracted the serum of the intercolumn cell test subjects and injected them into the body of the experimental animals.

Among them, they have fecundity by being born for two months, with four to five litters a year, one to seven litters. Then, the most cost-effective animal with relatively high genetic similarity, the white rabbit, became the world's experimental animal. Then, after injecting serum from the intercolumnar cells, these two-month-old white rabbits became spermatozoa.

This refinement is the refinement in every sense. First of all, under the serum of the intercolumnar cells, the body structure of the little white rabbit has undergone a huge change, and it has slowly transformed from a previous beast into a humanoid creature. And, it's not just the shape of the body that has changed dramatically. Immediately after that, they developed an astonishing amount of intelligence. With this wisdom, the world can no longer treat them as beasts, and they will have a new identity of their own - ninja beasts.

The appearance of the ninja beast, the hairy rabbit family, indicates that the serum of the intercolumn cells does have a positive effect. For this reason, the world found Uchiha Kitamiao and invited him to participate in clinical trials.

For the physical transformation of this foreign substance, Uchiha Beimiao, who has a cell-free rejection reaction, is naturally happy to accept it. So, under the power of this serum, a huge vitality began to appear in his body. However, there is no obvious role as the hairy rabbit family, and for Bei Miao, this blessing of vitality is only temporary. However, even if it is a temporary increase in the body's energy, this serum has a high medical value.

It can be said that this is a universal medical agent. Even a dying person can continue to gain +1s under the effects of this potion. Then, by virtue of the life-sustaining effect, the user can delay until the arrival of rescue.

Of course, this is just ordinary usage, and for ninjas, this potion is a powerful buff. Among them, it can increase its own chakra control ability, and the strength of the control ability is related to the ninja's efficiency in using the ninjutsu chakra. In addition, it can also be used as a soldier food pill. According to world statistics, one unit is a dose of one hundred milliliters, which can support a ninja for two days of high-intensity combat.

Eventually, after all the effects of this serum were developed, the production of the serum was classified as a state secret by all the islanders of Tuan Fan Island.

Finally, there is the third direction of research. In this research direction, the world is preparing to clone a clone from its own cells and inter-column cells. Then, using the clone's bloodline as a buffer, the world will implement the original idea of transplanting intercolumnar cells.

And this idea, someone has already completed this experiment in the future, and this person is Shimura Danzo. Among them, relying on the special constitution of a man named Shin, Danzang completed indirect control by transplanting intercolumnar cells and writing chakran eyes on his arm. In other words, Danzang controls Shin's right arm, and Shin's right arm controls the cells between the columns and the writing wheel.

Uchiha Kitamiao has the same physique as Shin, but the world doesn't think much of him. The peer relationship is one thing, and the other is because she doesn't think this method of using a special constitution to control the cells between the columns may not be very effective. After all, the intercolumnar cells are just too aggressive. Even with the suppression of the kaleidoscope writing wheel, the world has no way to completely obtain its power.

So, in this research direction, the world is ready to transplant the tissues of clones that are related by blood. And, on this tissue, the world intends to transplant intercolumnar cells.

At this point, the purpose of the world is already obvious. It was herself, through the organization of the clone, to indirectly obtain the power of the intercolumnar cells.

The idea was well thought out by the world, but its research did not go very well. Because, all clones die unexplained at the stage of embryonic development. The cause of death is constantly being investigated by the world. At the same time, new embryo experiments are being carried out all the time.

After that, the cause was not found, and the world had to stop experimenting. Because, if this experiment continues, there is no point in it.

In this regard, during a breathing outside, the world looked at the wild cat in heat in the spring, and a bold idea flashed in her heart - she was going to transfer the embryo into her own womb. Among them, the idea of the world is to use the mature reproductive system naturally developed by human beings to naturally produce this embryo. According to the law of development, the embryo under this practice can be almost 100% viable.

So, she became pregnant......
