At night, after Uchiha Kyo came back from where he was, he went directly to Uchiha Fugaku and asked for the clan's classics.

But he didn't mean to open it now, but instead thought about where he learned medical ninjutsu from Dou today.

Strictly speaking, Uchiha Kyo did not master Yan Dun (Yang), although he was in the state of the Seven Gates, and the red blue flames all over his body turned into golden flames.

But that kind of situation is a quantitative change that causes a qualitative change, and the powerful body energy that erupts through the state of the seven gates is the main eight gates of Dunjia Chakra, and the effect of Yang Dun Chakra has been achieved.

Take Mu Dun as an example, he can only use the great snake nagi that is as mysterious as the advent of the Flower and Tree Realm, and the art of Mu Dun and Mu Ren, but he can't use BC-level ninjutsu like Mu Dun, Wood Ingot Wall, and Mu Dun and Tree Binding Eternal Burial.

The ability of a bloodstain should be from small to large, not just the ultimate mystery, which is not normal.

So he wanted to see if medical ninjutsu could give him some help.

Medical ninjutsu requires good chakra control and yang escape vitality, which are too easy for Uchiha Kyo, so it only took a few hours to initially master medical ninjutsu.

"Medical ninjutsu is the practitioner's use of Yang Escape Chakra to harm and heal the human body..."

Thinking of this, Uchiha Kyo took out the fish he bought today from the water altar next to him.

"I'm sorry!"

Watching the fish stare at him, the fish's eyes glowing with an eerie light.

Uchiha Kyoshi smiled, concentrated the Yang Dun Chakra in his index finger, and swiped lightly at the fish, the fish suddenly trembled slightly, and a wound burst out.

Chakra scalpel!

This is the destructive side of medical ninjutsu, and Tsunade's Strange Power Fist also falls into this range.

"Next is the healing aspect!"

Seeing that the fish was half-dead, Uchiha Kyo moved in his hand, and a gentle and delicate chakra condensed in his palm and pressed it.

Palm Immortal!

In less than a moment, under the effect of this delicate and gentle chakra, the wounds on the fish's body began to heal, and it began to jump alive again, and its eyes glowed with a strange light.

After hesitating, Uchiha Kyo put the fish back anyway.

"Let's try it!"

With that, Uchiha Kyo stretched out his right hand, and the acupoint came out of the two attributes of wind and fire chakra, which was rotated and compressed at high speed, and after a while, a chakra ball of blue-red flames was formed.

Join the Yang Escape Chakra!

Uchiha Kyo's heart moved, and in the way of medical ninjutsu, he poured the Yang Dun Chakra into the Chakra Ball, and the Chakra Ball began to emit a trace of golden light, the golden light was pure and vast, and began to spread slowly.

May I?

Uchiha Kyo carefully controlled, and the golden light of the chakra ball became more and more, and it occupied half of it in a short time, which was something that he could only do with Zhu Tianqi when he opened six doors.

Bang!

Suddenly, the chakra ball in his hand became extremely unstable, and it exploded in an instant.

No way?

Uchiha Kyo's brow furrowed.

Is it because I haven't mastered medical ninjutsu yet?

After several more attempts, but still unsuccessful, Uchiha Kyo put him aside and planned to study the clan's texts.

But fortunately, medical ninjutsu is still of great help to him, and he can already form a qualitative change in the state of seven doors in the state of six gates.

"Our people have the supreme writing wheel eye ....."

The opening chapter is about the introduction and research of the Uchiha ancestors on the writing wheel.

"Gifted clansmen will awaken the Supreme Eye, Kaleidoscope Writing Wheel Eye, under strong emotional stimulation...."

Uchiha Kyo didn't care, this was not what he wanted, and turned it over directly.

"There is also an eternal kaleidoscope above the kaleidoscope eyes, the ultimate form after the fusion of two pairs of kaleidoscope writing wheel eyes, only one of our clan has ever possessed - Madara Uchiha!"

Seeing this, Uchiha Kyo was stunned, he didn't expect that the book that Uchiha Fugaku gave him actually mentioned Uchiha Madara, and the secret of the eternal kaleidoscope should only be known by the patriarch, and the elders have no right to know.

It is also mentioned later that Madara Uchiha's eternal kaleidoscope comes from his younger brother Izuna Uchiha, as there is only one such example.

The scriptures are not sure whether in addition to brothers, fathers and sons, sisters, brother and sister, mother and daughter and other close relatives can merge into an eternal kaleidoscope like the Madara brothers, plus the clansmen of the awakened kaleidoscope are too rare to witness this.

Uchiha Fugaku really values me, so tell this secret directly.

Repay grievances with straightforwardness, repay virtue with virtue!

Your son Sasuke's business is on me.

Calming down, Uchiha Kyo's gaze down again.

"The pupil power of the writing wheel eye represents the power of the spirit, the Yin Escape Chakra based on the ultimate spiritual energy..."

Here it comes!

Uchiha Kyo's spirit suddenly lifted his mind and looked at it carefully.

Yin Chakra, since it is a chakra, it must be a fusion of physical energy and spiritual energy, but it is mainly based on spiritual energy.

"Yin Yin is in charge of spiritual energy, creating forms from invisible..."

The following is also a detailed description of the various pupil jutsu of the kaleidoscope and the various forms of artifacts of Susanoo.

"Izanagi.... Izanami...."

Finally, it introduces the pupil power that combines the spiritual secret technique and the writing wheel eye, and develops two Uchiha ultimate forbidden techniques that exert functional effects with ordinary writing wheel eyes and are not under the kaleidoscope writing wheel eye pupil technique.

However, Uchiha Kyo has no intention of learning, just to understand the working principles and effects of the two ninjutsu.

Time passed like this, minute by minute,

After a long time, Uchiha Kyoshi let out a long breath, closed his eyes, and pondered what he had gained.

Create form out of the invisible!

Uchiha Kyoshi opened his eyes, revealing a scarlet color, stretched out his right hand, and a stream of wind and fire chakra condensed in it.

Pour into the Yin Escape Chakra!

Uchiha Kyo's eyes became even more scarlet and mysterious, and cold and gloomy chakras began to flow from his eyes into the chakra balls in his palms.

Bang!

Like Yan Dun (Yang), Yan Dun (Yin)'s chakra ball has become extremely unstable to a certain extent, exploding directly.

What's missing?

Could it be that the combination of Yin and Yang Xuan's blood inheritance requires more conditions than the ordinary blood inheritance?

"Let's do this first, and in three days, I'll go and talk to the water gate, and go to find Nagato!"

Uchiha Kyo originally wanted to take advantage of the past three days to study the results of the two bloods, and then go to the rain ninja village to see, the two are likely to fight, although Uchiha Kyo is not afraid, but the stronger the strength of the hole card, the better, the more, the better.
