Xin is very confused now.

His body does feel discomfort from time to time, but it does not affect training and life at all. A while ago, Sai inexplicably used some clumsy techniques to check his body for him, which made him both funny and touched, but today he actually did this...

And I really found the problem.

It's just a difficult wind and cold, how come it becomes a special disease that is difficult to detect?

Yes or no……

Is the medical ninjutsu of Mingchao consultant not very good?

The thoughts of rudeness flashed through his mind.

At this moment, the door of his dormitory was suddenly opened. Ming Chao walked in outside the door and felt a little embarrassed when he was caught doing bad things in an instant. However, the person next to Ming Chao instantly made him throw away that part of the embarrassment.

"Big, Lord Orochimaru?!"

"Hmm? Do you know me?" Orochimaru said unexpectedly: "Oh, at this age, when you became the Root Reserve, it happened to be the last time I was still in the roots of Konoha, right?"

Shin nodded, then looked a little nervous, obviously remembering some rumors about Orochimaru. Nakamaru comforted him, "Don't be afraid, Senior Orochimaru came for the unknown disease in you... How to do it?"

As he said that, he looked at Orochimaru again.

"There are no testing instruments here. If it is not convenient to take him away, I can only extract two tubes of his blood first." Orochimaru is far inferior to Mingchao when it comes to medical ninjutsu alone, and knows that doing extra examinations will not be effective.

He took out the seal scroll, formed a hand seal, and spread out a slender needle.

I couldn't help but feel even more nervous, but I couldn't resist the two adults and could only get two injections in a row.

Ming Chao pulled the letter into the duel arena.

...

In the afternoon, Nagato was on the side, and he really couldn't deliberately pinch the letter or do some tricks to bring the letter into the battle.

I planned to do some special examinations for the letter before leaving the village, but Orochimaru came to get the injection, which saved Mingchao the trouble, and the 80% probability of C-level ninjas being easily drawn as always.

Ming Chao looked directly at Xin's bloodline composition.

【Letter (Class C)】

【Combat Power: 233698】

【Bloodline composition:

Mixed high-quality bloodline 33.1%

Mixed Lower Bloodline 66.9%】

Ming Chao's eyes flashed.

The duel arena is as powerful as ever, and the special letter is clearly written on it!

There is no medium bloodline of even 0.1%, only high-quality and low-quality! There is one such special person in the duel arena, Maitkai, and he is only high-quality and medium-quality, no low-quality!

If you don’t have a moderate bloodline, you will get sick. If you don’t have a low bloodline, you will not permanently damage your body no matter how you exercise, and you will become a genius of hard work.

Does anyone have no high-quality bloodline?

What will happen to these people?

The answer is easy to conclude. There are probably a lot of people with only medium and low bloodlines, just those civilians who cannot extract chakra!

"The best bloodline represents the talent for extracting chakra's practice, the lower bloodline represents the shortest plate and limit of the human body, and the medium bloodline represents... sound and normal?"

Mingchao couldn't help but think deeply.

Thousands of years ago, when Otsutsuki Kaguya did not arrive in the ninja world, there was no chakra in the ninja world.

At that time, people might have only medium bloodlines and low bloodlines in their bodies. It was the influence of the divine tree that caused some of the genes to change, and some of the medium bloodlines and low bloodlines transformed into high-quality, and had the ability to refine chakra and become ninjas.

So when there are only medium bloodlines and low bloodlines, what will happen if there are only medium bloodlines and only low bloodlines?

"Disabled..." Ming whispered super lightly.

He suddenly understood the origin of the blood-recovery disease!

I also know why this disease is called "Hexuejian". Most of it appears in the Blood Essence family, and there are special cases like this.

In order to maintain the integrity of bloodline, the Xueji family has many close relatives, but it is rarely heard that the Xueji family will have children with congenital diseases!

Children who should have congenital disabilities, because of the emergence of chakra, the balance of mixed high-quality bloodlines, and even the proportion of high-quality bloodlines due to the lack of medium-quality bloodlines, have become stronger geniuses!

And these geniuses often have short lives.

The cause of the disease is unknown, and they are all called blood-responsive disease!

"If there were no chakra, and like Junmaro, would he be mentally retarded?"

Trust may be caused by a congenital problem, or it may be caused by some situations of parents who do not know their identities.

Ming Chao suddenly thought of Itachi and Itachi's situation. Perhaps it was not as simple as the results of Tsunade's examination, but it seemed that the situation was not as serious as Shin-hwan and Kummaro? There were 0.1,0.2% of the medium bloodline, or was the Uchiha bloodline itself more sound than the Kaguya clan's bloodline?

I'll find out sooner or later.

And the progress of this bloodline exploration has indeed brought him great help as Ming Chao expected.

His experience of the best, medium and low bloodlines is more profound and specific, and he will probably be able to become more and more at ease when changing bloodlines.

He can convert it into a personal experience of this imperfect bloodline, or he can convert it into an alternative genius like Kai to practice physical skills.

Continue to gain improvement in strength.

...

Two days later, in Yinnin Village, Orochimaru's laboratory, Orochimaru stared at the black technology gene detector and checked Xin's blood test results.

Naochao next to him couldn't understand the messy patterns at all. He waited for Orochimaru to look away before asking, "Is there any similarity with Kummaro?"

"Not at all." Orochimaru looked a little strange: "Isn't it a bloodline problem? Nakayaka, are you sure that the child's illness feels exactly the same as that of Kummaro?"

Ming Chao smiled: "Although I was killed by Junmaru's eyes many times, I'm sure there were no omissions in the inspection just now."

Orochimaru also smiled hoarsely: "I'm really sorry, Ming Chaojun. That child once lost to you in one move and half a move, and he has been resentful. I don't know how far the gap is now."

As he said that, he sighed again: "The secret of blood is indeed not easy to reveal. Where is the difference and connection between people? I said that two days ago, but I still didn't have the intention to bring me into the duel arena. I couldn't experience it myself. It's a pity."

"You may be able to learn about the genes of plants?"

Orochimaru: "Haha, is Ming Chaojun urging me to work? I understand."

Ming Chao smiled and said, "There is another presumptuous request. Can Senior Orochimaru sort out a piece of your blood research results... to show me? Just have the basic knowledge."

Orochimaru licked the corner of his mouth: "Are you interested in my speculation about how touching changes your own bloodline? No problem, if Ming Chaojun experiences progress in the duel arena, I hope I can share some results with me."

"certainly."

So when Mingchao left Yinin Village, he brought a few scrolls of books and research records.

Autumn goes and winter comes.

The 56 years of Konoha have passed quietly.
Chapter completed!
