In the gloomy underground research institute, the imaginary dampness is not there, but it is dry and bright, but there are a little more winding serpentine passages.

With a creak, the door of the research room slowly opened, and the medical ninjas wearing protective masks were busy, and at this time, a figure intercepted the comer.

"Lord Night, the people behind you need to sign a non-disclosure agreement."

A guard wearing a protective mask respectfully walked up to them and stretched out his arm to intercept them, and the Uchiha nodded with a smile when he saw this, "Okay." ”

"Kakashi, you're here to sign a non-disclosure agreement."

Signing a confidentiality agreement, which will only be carried out when stepping into some kind of secret base in the village or attending a secret meeting, Kakashi Hagi was even more shocked when he saw this scene, this was actually a secret research base in the village.

Although he was on a mission, he knew that if this was really private, he would never let him in, so this was definitely a research base in the village, and it was formal and legal.

If it's private, don't say whether he can come, and even if he can, it won't be a non-disclosure agreement.

Kamishinobi is eligible to participate in various secrets in the village, and at the same time, because of some needs, he can enter certain secret bases after signing a confidentiality agreement.

"Okay." Kakashi Hachiki respectfully took the pen and scroll, and when he signed his name, he left his own fingerprints to enter.

"Kakashi, Orochimaru-sensei now belongs to the roots, since you have been in the dark department, then you should naturally know, so I won't say more."

Walking inside with Kakashi, Uchiha Ya said with a relaxed smile, as if the two were confidants and friends, and Kakashi remembered his mission deeply, and couldn't help but pretend to be puzzled, and said indifferently: "Then what is studying here?" ”

In the face of Kakashi's inquiry, Uchiha Ya showed an apologetic smile and waved his hand, "I can't say the secrets of the research, but the rest are not confidential, I can tell you." ”

"The research here is responsible for cultivating limbs and organs, making limb and organ transplantation technology more mature, and even achieving the purpose of self-cultivation, so that there is no need to do anything to those death row prisoners and spies."

In the upper ninja stage, it is no secret that the transplantation of limbs and organs has long been a pity, after all, if a upper ninja breaks his palm or loses an organ because of battle, it would be a pity to directly reduce his personnel in non-combat.

On the contrary, it is normal to find an organ or limb that also has chakra without rejection, and most of the spies, traitors, and death row prisoners will end up like this, and even in wartime, the captive ninjas of the enemy country will also be included in the target, after all, cutting the other party's flesh to nourish themselves, and anyone else will do the same.

It's just that these are all unspoken rules acquiesced by the five major countries in the ninja world, and they will not be moved to the table, and there are too few other small countries that can achieve this kind of technology.

Kakashi Hachiki looked at the dazzling base, which was full of petri dishes, including arms, thighs, and even various organs such as the heart, as if some kind of cruel cultivation experiment was going on here.

"Night, you are!"

At this time, Kakashi Hachiki was a little silent, as if he felt that the other party was trying to pull him into the water, after all, although he was a pure ninja, he was not stupid, how could he not see that what the Seventh Police Division had done recently was a signal on behalf of Orochimaru to the village, a signal of his Orochimaru's political intentions.

Kakashi's appearance was naturally seen by the Uchiha Night, and he directly showed an apologetic smile, and then when he looked around and found that no one was paying attention to them, he couldn't help but slow down and whispered in Kakashi's ear as the two walked forward in parallel.

"Kakashi, there's no way, if you don't suppress your thoughts, your chakra will be consumed all the time, in this case, if you don't adapt to the premise of writing wheels, you will almost be wasted, even if you adapt, your cultivation will be affected in the future."

Kakashi has a chakra eye that automatically consumes chakra all the time, in this case, he can hardly concentrate on cultivation, it can be said that there is almost only one direction of Kakashi's cultivation now, and that is control!

A genius, dragged down by a writing wheel, will drag the former genius into the abyss.

Especially at this age, which is the explosive period of every ninja's development, Kakashi almost stopped because of the writing wheel.

Looking at Uchiha Yaya's apologetic smile, a warm current rose in Kakashi's long-sealed heart, and he couldn't help but bow his head and say in a deep voice, "Ye, thank you." ”

"Hehe, Kakashi, don't worry, I won't make it difficult for you, and when the time comes, your eye problem will be solved, and you won't have to worry about anything."

Uchiha Ye nodded with a smile for the sake of his old classmates, as if to say that although he was in school for a short time, he still had feelings.

Kakashi, on the other hand, has another sense of guilt in his heart, he will never be merciful to his enemies, even if it is a traitor from the same village, but this time he wants to use his companions.

At first, Kakashi thought that his old classmate was going to drag himself into the water to join the Orochimaru family, after all, there were some things he could still see.

One is the name of his flag tree, eight years later, the prestige of the white fang back then is still there, especially when he became a ninja at the age of twelve, these invisible things and connections, for ordinary ninjas, may be nothing, but for politicians are very important.

Another genius ninja who is also Konoha himself, a twelve-year-old upper ninja, is enough to attract some young ninjas.

The prestige of his father, the prestige of his father, the student of the four generations of Hokage, and the fact that he himself is a genius ninja, these three together are some invisible political accumulation, and whoever gets Kakashi can get these three political investments.

So Kakashi thinks that Uchiha Yaya is trying to drag him into the water, but that doesn't seem to be the case at the moment.

"Don't talk later, leave everything to me, don't worry, Teacher Orochimaru's mind won't be small."

The Uchiha winked at him with a smile, as if to say let's take the benefits first, and you don't have to worry about the rest.

However, in Kakashi's eyes, there was a feeling that the other party didn't want him to get involved in this troubled water.

Kakashi Hagi joined the Seventh Police Division, on the surface, one is cultivation, and the other can be regarded as a political investment, but this, like Inuzuka and Oil Girl, is an ordinary political investment.

And Uchiha and Hinata are a little different, and they have already directly bet on Orochimaru and made their position clear.

Therefore, in Kakashi's eyes, Uchiha Ya seemed to not want him to be completely involved in this troubled water, and it was precisely because of this that he felt a little guilty in his heart.
