Uchiha Kotogawa from Konoha

Time flies is half a year.

It was rare for Qinchuan to be busy. He remembered that the last time he was so busy, it was because he wanted to understand the principle of the pupil technique and decipher the pupil technique and the secret technique.

The Yin Seal has to be said to be a very magical technique.

Once Kotokawa started drawing, she understood.

To put it simply, the Yin seal is a ninjutsu method, in which a storage space similar to a sealing scroll is placed on the human body in the form of a sealing technique.

The storage capacity of this Yin Seal designed by Qinchuan himself is much larger than the ordinary Yin Seal space.

Not long after she started arranging the Yin Seal, Qinchuan realized that her innovation was actually not very clever.

Because the Yin Seal Technique itself can achieve the effect of shrinking the spell runes as she imagined, leaving more drawing area.

"The technique of Yin Seal was probably not created by Tsunade."

Qinchuan came to such a conclusion.

"Tsunade is most likely not good at craftsmanship and has not learned the advanced methods of drawing Yin seals, so she can only arrange Yin seals with Lin's level of capacity."

"In other words, Tsunade actually knows how to draw more advanced drawings, but for some reason she doesn't want to draw advanced versions for others. Maybe she finds it too troublesome, or maybe she just wants to save a little bit."

It took Qinchuan more than a month to get familiar with it before she actually started to draw it. It took her almost four and a half months to finally complete the Yin seal she imagined.

The amount of chakra that the entire Yin Seal space can hold is massive.

Enough to hold about [-] cards.

This level of capacity far exceeds that of tailed beasts, and the combined capacity of the nine tailed beasts is only this.

Kotokawa suddenly had the illusion that he had become the Jinchūriki of the Nine Tailed Beasts.

She smiled: "I remember that chakra can carry spiritual will. If these chakras that belong to me have spiritual will, wouldn't it become a chakra aggregate? In other words, this is A tailed beast.”

Thinking of interesting things, Qinchuan couldn't help laughing.

But in fact, her chakra cannot have spiritual will, because the chakra already carries her own spiritual will, and it is completely impossible for another will to appear.

Unless she suffers from mental illness and split personality.

Standing in front of the mirror, Qinchuan lifted his bangs from his forehead and looked at the mark between his eyebrows.

This is a small hexagonal windmill pattern, with a small hollow in the center of each curved blade.

That's right, Kotokawa Takumi changed the mark of the Yin Seal into the pattern of his own Mangekyō Sharingan.

"Hehe, this baby is a genius!"

Qinchuan was a little proud. She had successfully expanded the use of another technique, and it was very successful.

In the next few days, Qinchuan repeatedly opened and closed the Yin Seal to test the performance of this technique, and also checked for bugs.

Her current situation is a bit like that of a programmer, who builds a complex software and then tests it on the front end while finding bugs on the back end.

For more than half a month, Qinchuan re-examined and sorted out the structure of the Yin Seal and repaired a few awkward connection points.

By the way, she also filled up the five separated spaces of the Yin Seal, two of which were used to store chakra, two were used to store senjutsu chakra, and the last one was used to store eye power.

The first two are quite easy, but the last space for storing pupil power has only been reserved a little so far, far from being full.

She doesn't have other types of energy yet, so she can use the extra space first. When new types of energy are developed in the future, she can free up the energy in the chakra and magic areas.

"Very good, perfect."

Kotokawa applauded himself for yet another success.

"I am indeed an extraordinary genius. I just don't want to do meaningless things, hehe."

The space vortex rolled up, and Qinchuan left the Kamui space.

At home, the girls, one young, two young, and three young, had gathered together. When they saw Qinchuan coming out, they all looked over.

Xiao Lin couldn't wait to rush into Qinchuan's arms. He looked at her with big watery eyes and said, "Sister, are you finally done?"

Qinchuan smiled and kissed the little girl on the face: "Yes, it's done. I can also make a simplified version of the Yin Seal for Xiao Rin. When you grow up, I will give you another one like mine. Premium version."

Xiao Rin is very happy, but the reason why she is happy is not that Qinchuan wants to get a Yin seal for her, but that during this period, Qinchuan has been busy drawing Yin seals and has not been able to seriously accompany her for a long time.

"Come and pat your head and comfort my little cutie."

He held Xiaolin and spun around in a circle.

The girl's face is full of smiles.

"The spacecraft has been initially completed and testing can be carried out at any time."

At the Konoha City Government Office, Orochimaru said as he pushed out a thick document.

Qin Chuan casually opened it and took a few glances. It recorded the manufacturing process of the spacecraft, starting with the materials of the spacecraft, down to the energy lines, and finally the layout of the spacecraft.

Two days have passed since Qin Chuan completed the Yin Seal. The day after she came out of seclusion, she went out for a day with Nohara Rin, Xiao Rin, and Xiao Chuan.

Then I came here to see Orochimaru.

"Not bad, I thought you would be clever if I didn't come over for half a year, but I didn't expect you have succeeded. It's very good."

Qin Chuan praised.

"If you can give me a copy of Izuna's Eye Technique, I can complete it faster and make many interesting things."

Orochimaru said with a gentle smile.

"That's not necessary." Qinchuan said simply.

A trace of anger flashed in Orochimaru's eyes. He was so confused that he agreed to let Kotokawa take away those eyes.

In fact, when he wanted to refuse, he had no choice but to do so. Qinchuan would not tolerate him.

Ever since he completely digested Izuna's memory, Orochimaru realized how powerful that eye technique was.

That is the most suitable pupil technique for scientific researchers. Although it cannot increase combat effectiveness or life-saving ability, it can make real matter change to form what one wants.

This is an absolute treasure for scientific researchers.

Unfortunately, everything is gone.

In addition, Orochimaru also realized a problem. According to Izuna's memory, Kamui is the Kaleidoscope Eye Technique, which cannot be learned. However, Kotokawa was able to let him learn the Eye Technique a long time ago, which is outrageous.

To sum up, Orochimaru is very sure that Kotokawa has a secret, and the secret is very big. It is unscientific for her to be able to crack Uchiha's unique kaleidoscope eye technique.

Of course, it's normal for ninjas to have secrets, but Kotokawa's secret is even more curious.

"Kotokawa-san, come with me and take you to see the spaceship developed by Izuna in secret."

Orochimaru stood up and signaled.

Kotokawa had no doubt that he was there, and calmly followed Orochimaru underground.

Under the city hall, there is a well-developed subway transportation that can lead to every corner.

"Master Quanna!"

The ninja guarding here nodded slightly, glanced at Qinchuan, but quickly took it back.

But he had some doubts in his heart. He remembered that Mr. Izuna should not have such a number one female secretary.

But it's not his turn to worry about these things.
