Water, fire, earth, wind and thunder, these are the five elements of this world. In addition to the five elements, there is also Yin and Yang.
Yin, spirit, illusion, intangible. Yang, flesh and blood, material, tangible.
Now able to freely use the five changes in chakra's nature, Kaito began to explore the realm of yin and yang.
Compared with the changes in the nature of the five elements, although everyone has the nature of yin and yang, it is more difficult to sense and extract it.
But there is also a simpler way, which is to learn the corresponding ninjutsu and use the ninjutsu to stimulate the yin and yang attributes and in turn sense it.
When it comes to ninjutsu with yin and yang attributes, the more iconic ones should be the Nara clan and the shadow secret technique and the Akimichi clan's doubling technique.
These two ninja families are friendly to the Senju clan, and their respective strengths are very powerful. It is obviously impossible to obtain them by force.
So we can only use other methods, such as stealing, fraud, and trading.
During the Warring States Period, the death rate of ninjas was extremely high, and the families that could survive for a long time were basically large and prosperous families.
The three families of Konoha have been established for a long time, and naturally they are also big and prosperous families.
And because of the cruelty of the Warring States Period, not only adults had to go to the battlefield, but also children under the age of ten.
Kaito asked rats to monitor the children and teenagers of the Nara clan and Akimichi clan. Every day, Kaito summoned those rats and listened to their reports. Although these rats could not report back too detailed information, their location, number of people It can still be reported clearly.
Based on this simple information,Kaito can track those little guys when they go on missions.
Ninjas know how to hold their breath, which is not just as simple as holding their breath, but also includes the control of chakra and the control of the rhythm of action.
Although the strength or weakness of the breathing technique cannot represent the strength of one's strength, it can represent one's professionalism as a ninja.
Kaito's breath-condensing technique is very powerful. It may be because he is a rat, and he has now understood the natural chakra. In addition, because he can use all five attributes of chakra, he can completely control himself. The atmosphere blends into the surrounding natural environment.
No matter in the forest, in the water, in the yellow sand, in the rocky hills, or in the cold wind and heavy snow, unless there is a specialized perceptive ninja, he cannot be found.
Even though they were only a hundred meters apart, and even though there were only some shrubs and woods between them, no one noticed that there was a stalker behind them.
This combination has been formed during the Warring States Period. Generally, tasks are completed by this combination, and the commissions received by the three major families are generally shared.
This commission was a letter delivery task. Since it was not an important letter and the commission fee was only 10,000 taels, it was left to the young people in the clan to do it.
In this era where the average lifespan of a ninja is only 30 years old, those under 15 are the so-called young people here.
Even if there are no young children, as long as they are ninjas, they will not be able to live under the wings of their elders.
They begin training when they are three or four years old, and start running missions when they are six or seven years old. In war-torn times, they go to the battlefield when they are seven or eight years old.
Although future generations need experience, in this world and this era, this experience is too cruel.
Children as young as twelve or thirteen can already kill someone calmly or even while talking and laughing. Of course, there is a high chance that they will be the one who is killed.
The trio of Boar–Deer–Butterfly who went on the mission this time were three boys of twelve or thirteen years old. They held the letter of entrustment and headed for their destination. Delivered smoothly and returned.
However, their return trip was not smooth.
They met their enemies.
Enemies are too common for ninjas. Although there are few old enemies like Uchiha and Senju that last for hundreds of years, every ninja family must have several enemies.
Although they are a very versatile combination of Boar–Deer–Butterfly, their enemies are five adults in their twenties, and they are not geniuses, so they cannot defeat them, and they did not escape.
They are unfortunate, but also lucky.
Just when they were desperate and helpless, just when they were almost killed.
"Boom!" The water curtain that suddenly rose from the ground blocked the oncoming fire dragon.
The collision of water and fire causes water vapor to evaporate and mist to spread.
In the dense mist, a strange figure loomed.
"Ah——!" Every time he appeared, he would be accompanied by a scream.
When no one can distinguish the surrounding situation, Kaito is able to accurately sense everyone's position and movements with the most natural chakra induction.
He walked freely through the fog, harvesting lives one after another.
Finally, when the fog cleared, Kaito stood in front of the three boys.
The three boys looked at the Kaito in horror. Although they subconsciously took a defensive posture, they knew that they were unable to fight against the rat plague.
"I killed your enemies, so I saved your lives." Kaito said to them calmly, not paying attention to their alertness.
"Since I saved your lives, your lives are now my property. And I am going to use your lives in exchange for your respective families' secret skills. I feel this is a very reasonable thing." said Then, Kaito looked at the kid from the mountain clan again.
"Kid, I advise you not to act rashly. If I judge that you are a threat to me, then I will kill you." The murderous intention in Kaito's tone was very serious, but there was a strange kindness in it, because he was like this The words are really advice.
The trio of Boar–Deer–Butterfly were all stiff. When facing the Kaito, they felt a thrilling sense of fear. It didn't feel like they were facing an enemy, but like they were facing some kind of ghost.
Obviously, the attitude of the Kaito is not too bad, and it is much gentler than those of the enemies, but they can't help but feel a feeling in their hearts: they will be eaten.
"Family... the family secrets are not allowed to be leaked." One of the boys said while suppressing fear.
"You don't need to be embarrassed, because I'm not a human being, and I don't belong to a certain faction among you ninjas, so if you teach me your secret techniques, you won't be punished by the family." Kaito told them patiently. To enlighten.
"On the contrary, your elders may reward you because you can achieve a friendly relationship with me at such a small price, which is good for the development of your family. Maybe in the future, I may Such a friendly relationship will help you."
Seeing that several boys were still doubtful and hesitant, Kaito gave an example.
"For example, in terms of psychic beasts, although I myself will not sign a contract with ninjas, my rat tribe can sign a contract with you."
Under the influence of Kaito the three little guys finally accepted Kaito's proposal and explained the secret techniques they mastered to Kaito.
Kaito was not sure whether what they explained was right or wrong, but he still kept his promise and let them go. Even if there was something wrong with the secret technique later, he could find an opportunity to kill them again. This was not difficult.
