Butterflies, butterflies of butterflies.

As the name suggests, the development of Gu Qinghe's ninjutsu must be related to butterflies.

Gu Qinghe knew that although the ninjas in the Naruto world had strong destructive abilities, there were too few ninjas who could fly.

So flying has become Gu Qinghe's research goal, after all, with flying, he has a stronger ability to escape, as soon as there is a wind and grass, he will fly into the sky, who else can catch him?

Flying, flying, wanting to fly, how easy it is to say.

Most of the creatures with wings are able to fly, so Gu Qinghe put his research direction on wings, and he wanted to use his chakra to form a pair of wings that could make him fly.

If you want to condense the morphological changes of Chakra into a pair of wings, you also need to compare them physically.

So with this idea, Gu Qinghe often went to the back mountain of the ninja school to observe how the winged creatures there flew.

In the back mountain, Guqinghe found many flying creatures: all kinds of birds, dragonflies, butterflies......

Among these flying creatures, Gu Qinghe chose butterflies, and the reason for this is that the butterfly's wings are larger than its body, which is more contrasting value.

And the butterflies of that season are everywhere in the back mountains, and it will not let Gu Qinghe kill one because of research and can't find the second one.

Butterfly wings are butterfly wings, and Gu Qinghe's research on butterfly wings only studied the structure and vein of butterfly wings, and the rest of the dust on butterfly wings and the like, Gu Qinghe was not interested.

After five years of research and experiments, Gu Qinghe has long been able to condense the butterfly wings through the morphological changes of the chakra.

However, Gu Qinghe's dream of flying with the help of the conjugated butterfly wings was also shattered at the moment when the butterfly wing research was successful.

Because Chakra's energy was too light, Gu Qinghe's body was too bulky, and no matter how Gu Qinghe fluttered his wings, his feet couldn't leave the ground for a minute.

With the help of butterfly wings, the research on butterfly wing flight failed.

In Gu Qinghe's view, butterflies are divided into two parts: body and wings, and since the wings have been studied, Gu Qinghe also spent some time studying the body of the butterfly.

In this way, a complete butterfly was thoroughly studied by Gu Qinghe, and Gu Qinghe was able to transform and condense the whole butterfly with the change of chakra's form.

With Chakra to completely transform and condense a butterfly, this ninjutsu is the source of Gu Qinghe's development of "butterfly" ninjutsu.

In addition to morphological changes, chakras are also characterized by changes in nature.

Chakra is composed of cellular energy and spiritual energy, and each person's physical attributes are different, so the attributes of their cellular energy are also different, so Chakra also has corresponding attributes.

Chakra's attributes are mainly divided into five categories: earth, fire, water, wind, and thunder.

These five attributes in turn give rise to five changes in the nature of chakra, such as: wind cutting, thunder penetration, earth defense, fire blazing, and water penetration.

Of course, the avenue is divided into yin and yang, this sentence is obviously suitable for all worlds, and there are also yin and yang escape techniques in the Naruto world, such as: medical ninjutsu derived from yang escape ninjutsu, Yin escape ninjutsu shadow imitation technique of the Nara family, and so on.

Therefore, all chakras can be simply divided into two categories: yin and yang.

However, it is not easy to make one's own chakra produce one of the two attributes of yin and yang, after all, the yin and yang retreat technique is indeed a little higher than all the retreat techniques, and it is also a little more difficult.

The Oriental World is mainly the world of the five elements, and its components are, of course, the five elements of metal, wood, water, fire, and earth, so the physical attributes of people in the Eastern world are divided into these five elements.

And the Hokage world should be mainly composed of earth, fire, water, wind, and thunder, otherwise the attributes of ninja should not be dominated by these five.

Naruto's World Test Chakra attribute is judged by the Chakra Test Paper: if the Chakra Test Paper is broken from the middle, it is the wind attribute, if the Chakra Test Paper is wet, if the Chakra Test Paper is wet, if the Chakra Test Paper becomes fragmented, if the Chakra Test Paper is wrinkled, it is the Thunder attribute, and if the Chakra Test Paper is on fire, it is the Fire attribute.

Of course, because these five attributes are the five main attributes of Chakra, and the vast majority of people are one or more of these five attributes, the Chakra test paper can only judge these five attributes.

Chakra test strips were very expensive, and Gu Qinghe was a penniless orphan, so he couldn't test his chakra attributes in this way at all.

However, Gu Qinghe also has his own cognition of the change in the nature of chakra.

Gu Qinghe believes that the difference in cellular energy is mainly due to the different affinities of the human body to various components in nature.

Because of this, Gu Qinghe seriously felt the affinity of his body to the various components of the natural world.

Feeling affinity may be too abstract, but it's easy to do.

Gu Qinghe's cellular energy has attributes, and this attribute is Chakra's attribute, and this attribute is unknown to Gu Qinghe.

The Naruto world is composed of five components: earth, fire, water, wind, and thunder, and there are naturally a lot of five free energies between heaven and earth, such as earth energy and fire energy.

These energies can be determined by the senses: the dryness, warmth, or heat of fire, the coolness or wetness of water, the suffocation and heaviness of earth, the blowing of wind, the numbness of thunder, and so on.

As long as Gu Qinghe can perceive what kind of free energy is often exchanged between the cell energy in his body and heaven and earth, doesn't Gu Qinghe know what kind of attribute he is?

Then, after more than ten days of testing and verification, Gu Qinghe knew that his chakra nature should be water attribute, because he did find that the free water attribute energy between heaven and earth often did a regular exchange with the cellular energy in his body.

After determining the nature of his chakra, Gu Qinghe began to experiment with the change of nature, and then after more than half a month of experimentation, Gu Qinghe successfully changed the nature of his chakra.

Although the five types of chakra nature changes are the most lethal of wind and thunder, the aggressiveness of the chakra after the nature change is still much stronger than that of the chakra.

Because of this, Gu Qinghe integrated the chakra after the change of his water attribute into the "butterfly" ninjutsu.

The specific process is to create a chakra butterfly with morphological changes, and then add a change of nature chakra to the butterfly wings (wings) of the chakra butterfly, so that the butterfly wings of the chakra butterfly have a strong attack ability, and this chakra butterfly is called by Gu Qinghe - attack butterfly.

Gu Qinghe knew that his chakra attribute was only a water attribute, but Gu Qinghe was not satisfied with this attribute change.

So Gu Qinghe began to study the separation of chakra, he wanted to separate chakra, and study the specific changes of the yin and yang attributes of chakra, the root of chakra.

Medical ninjutsu is a kind of yang escape, and there are still some ninjas who can master medical ninjutsu, and Gu Qinghe thinks that he is no worse than them.

Therefore, Gu Qinghe went to the hospital to observe the scene of the medical ninja attaching the yang attribute chakra to his hand to heal the patient's injuries.

Gu Qinghe's spiritual energy already carried the sword intent of the first two reincarnation world cultivations, and his spiritual energy was really strong, so even if he was far away from the medical ninja who used medical ninjutsu to help patients, he could also feel the changes in the yang attribute chakra and the state it presented with his strong spiritual power.

Remembering the state of the yang attribute chakra, Gu Qinghe separated according to this state when he separated his own chakra, and then after a few days, Gu Qinghe separated the chakra of the yin and yang attributes.

However, yin and yang are opposites after all, and without a special method, they cannot get along after all.

Soon after they separated, they attracted and repelled each other, and then they merged and canceled out in Gu Qinghe's body.

Although chakra can be regarded as composed of two attributes, yin and yang, the ratio of chakra is not one-to-one.

And the ratio of yin and yang attributes in the body of the Guqing River is greater than one, that is to say, the yin attribute of Chakra in the body of the Guqing River is a little more than the yang attribute, perhaps this is the reason why the water attribute of the Guqing River is presented.

Knowing that he had a little more yin attributes, Gu Qinghe also focused on the nature change of the yin attribute chakra, and then it took a few months for Gu Qinghe to be able to extract a single chakra with the change of yin attribute.

The change in the nature of the yang chakra is light, while the opposite of it is darkness.

Therefore, in order to take advantage of the "dark" characteristics of the change of yin attributes, Gu Qinghe completely constructed a chakra butterfly with this chakra, this chakra butterfly is pitch black all over, and has a good concealment in the dark.

Note: All worlds are composed of yin and yang, and then yin and yang combine in different proportions to form different substances, such as earth, fire, water, wind, and thunder; The Hokage world is mainly composed of earth, fire, water, wind, and thunder, so chakra can also have a change in the nature of yin or yang after having a change in nature.
