Mito looked at Qingfeng gently, and said with a slight recollection: "When it was still the Warring States Period, the life of a ninja was not valuable, and the world was also a mess, and countless people died every day, so although some human experiments were carried out in the front room, although the pillars were unhappy, but in the case of all enemies, the pillars turned a blind eye and ignored them."

But with the establishment of Konoha, the war subsided, and peace gradually came, at this time, it was no longer possible to carry out that kind of human experiment, under the strict orders of your grandfather in the column, your grandfather in the door had to obey, but it was also in order to better conduct research, instead of human experiments, your grandfather in the door also put the research on the shadow doppelganger technique on the agenda, and finally really let him make it out, this is the shadow doppelganger technique.

Although the shadow clone can't completely replace the human body for detailed experiments, some rough experiments are still possible, so your grandfather's research can be carried out! ”

Hearing Mito's story, Qingfeng's heart flashed with a clear understanding, he really guessed correctly, things are all caused and effected, and it was precisely because of the pillar to stop the human experiments, so there was the appearance of the BUG shadow clone, but later it was used for reconnaissance, training and other purposes, it can be said that the highest achievement in the door is this shadow clone technique, don't look at his level is not high, but it is a divine art.

And today, Qingfeng stumbled into it by mistake and studied the forbidden technique, which is to test the true use of the shadow clone, which is no coincidence!

At the same time, Qingfeng admired Kazuma even more in his heart, it turned out that the human trial of Kazuma had begun since the Warring States period, and at that time, the life of a ninja was really worthless, and it was understandable that Kazuma was used to study with the help of the enemy's corpse.

After all, it was just a thousand-handed clan at the beginning, and there were no other people who blamed it, but now the old people of the thousand-handed clan are so afraid of the door, and it is estimated that they were also suppressed by the reputation of using human experiments at that time, and the young people don't know the history of the door, but those old people are clear.

Although human life was not worth much at that time, the name of human trials was still intimidating when you heard it!

Qingfeng looked at Mito with a look of reminiscence, even if he mentioned human experiments, he didn't think much about it, and even Tsuko's face didn't care too much.

In fact, it is understandable that the two of them have this kind of reaction, after all, Mito also came from the Warring States Period, and is used to seeing life and death, of course, the most important point is that Mito is still a very powerful medical ninja, and what does the medical ninja come into contact with all day long? There must be all kinds of corpses in the patient, and even Tsuko practiced medical ninjutsu with Mito back then, otherwise she wouldn't be able to master the acupoints of the human body and relax the spirit of the breeze.

In fact, it's very unfair to people who conduct human experiments like Kazuma, in fact, if it's about human experiments, medical ninjas and torture ninjas are only afraid to do more, not less, but these two ninjas are also the only two ninjas who will not be blamed.

What is the rationale for human trials? One is to better master medical ninjutsu, understand the structure of the human body, be able to better treat other ninjas, and save the lives of others, while the other is to torture other ninjas, steal information from other villages, and various ninjutsu, secret arts, and so on!

These two kinds of ninjas do human experiments, they are all righteous names, protected by righteousness, and no one has anything to do, just like the same autopsy, ordinary people dissect corpses is a crime, but the white-clothed angels dissect corpses for medicine, doctors and police officers occasionally kill people and will not blame them, medically it is called euthanasia, and in society it is called preventing others from committing crimes and endangering the safety of other people.

Sometimes you don't think that the doctor who euthanizes someone is cruel, but you just feel that he is very merciful, and the policeman who kills the gangster is a heroic act.

This shows how important the name of righteousness is, you see that even though Orochimaru later became one of the three ninjas, the name of conducting human experiments still made it smelly, and the crime was extremely evil, and his reputation in Konoha was ruined all of a sudden.

But if it is replaced by a medical ninja and a torture ninja, it will be different, of course, sometimes power can also form this effect, Orochimaru is Hokage will definitely not care about human experiments, just like secretly disgusting people do too much, but does Ape Fei care? Don't say they don't know, it's a lie to say they don't know!

After Qingfeng admired the great scientist, his chaotic spirit became more peaceful, and the stinging pain gradually disappeared, and to Qingfeng's surprise, he could feel that his spiritual power had increased slightly, and his soul had become more condensed

Could it be ······ A thought rose in Qingfeng's heart, he seemed to have found a good way to exercise his spirit, but ······ This approach seems to be a bit too torturous!

Thinking of the scene this morning and the encounter, Qingfeng still couldn't help but shiver!

"You! Although I know some of the uses of the shadow clone, it's too messy, and it's already good to have so many attempts at one time, and the spirit hasn't collapsed, after all, that kind of experience ······

Thanks to your natural strong mental power, your yin attribute is extraordinary, otherwise, there will be chaos this time, let's just say that it is your grandfather, and you don't say that you have tried dozens of times at a time! ”

Mito didn't know what he thought of, shook his head slightly, and then looked at Qingfeng Dao sternly, "What kind of forbidden technique are you going to engage in, grandma won't stop you, but you must not do this nonsense again, at most a few attempts at a time, so that it will not be too oppressive to the spirit!" ”

Under Mito's strictness, Qingfeng could only agree in the end, seeing Qingfeng's unusually well-behaved appearance, Mito smiled with satisfaction, "Okay, Tsuko, you take care of this stinky boy first, I'll go and serve the soup of the gods, and after drinking the soup, I will come to eat again, for you, our mother and mother didn't even eat lunch!" ”

Mito complained and went out of the room, and after listening to Mito's words, a trace of guilt flashed in Qingfeng's heart.

Then Seifu saw Mito walking in with a bowl of medicinal soup and a blushing Tsunade on his toes!

After drinking Mito's refreshing soup, the breeze rested for an hour in a relaxed mood, and only then did he recover slightly and become alive again.
