People are in Konoha, the start level is full

"Don't you want to experience the feeling of pooping? It's a great feeling. Moreover, there is not only poop, but also pee... You can also press the button of the toilet and watch your poop being flushed away..."

Bai Jue looked stupid and continued chattering.

"shut up!"

Black Zetsu couldn't bear it, so he shouted him down in a low voice, and then raised his head to look in the direction of Kurama Yan.

At this time, Kuramahiko was walking back and forth in the open space with a bored look on his face, passing the time, turning his head from time to time to see the progress of Orochimaru's surgery.

"As long as it's a technique, it can't be without loopholes. The same goes for this guy's ability. There must be some key points that I haven't discovered."

Black Zetsu recalled that not long ago, he followed and observed a B-level mission led by Orochimaru and Kurama Yan and others.

The content of that mission was to clear out a gang of bandits occupying a hilltop near Chidao in Kawanoguni. Although the bandits were small in number, their leader was a chuunin who had defected from Xiaoyin Village.

Naturally, Orochimaru would not take action on such a simple task, but would just stand in a hidden place and watch leisurely.

What puzzled Hei Zetsu the most at the time was that Kurama Yan could actually stand on the sidelines and watch. Moreover, he was not standing in a hidden place, but just standing on the edge of the battlefield.

Both the enemy and his teammates seemed to ignore him as if he were nothing.

Is it the ability to become invisible within a certain range, the ability to eliminate one's own presence, or is it an illusion?

At that time, he thought of many possibilities, but today, he was truly sure that it was an illusion.

"And when they carried out those missions before, I always thought that Orochimaru was also affected by his ability. Now it seems that Orochimaru should also be an insider."

Black Zetsu analyzed silently: "In this battle with Kakuzu, Orochimaru delayed it for a long time before Kakuzu was controlled by the brat. Perhaps, this illusion requires preparation time for powerful ninjas. This is also It’s in line with common sense.”

Kurama Yan's ability can easily control low-level ninjas and ordinary people. For masters, it takes a certain amount of time to prepare. After a series of intelligence analysis, Black Zetsu made this judgment.

"Then, how will his genjutsu perform against ninjutsu ninjas? And, for someone like me..."

"Ok?"

Black Zetsu was guessing when he suddenly noticed that Kurama Yan suddenly turned his head to look at their direction. To be cautious, he controlled White Zetsu and immediately sank into the big tree.

"Am I too sensitive?"

Kurama Yan looked into the depths of the woods and thought silently.

He seemed to hear vague movement from deep in the woods before, so he fired dozens of chakras directly there.

The result only links to a sparrow flapping its wings.

At this time, Black Zetsu had sunk into the ground and was moving rapidly towards Uchiha Madara's hiding place.

"Kurama Yan, even I am looking forward to your next performance." In the dark underground, the moving Black Zetsu showed an abstract smile.

……

a few days later.

Deep in the Death Forest of Konoha Village.

"Teacher Orochimaru, are you sure these instruments have been debugged? When can my chakra testing begin?" Kuramayan put one hand on his waist and walked back and forth in Orochimaru's expanded and spacious laboratory.

Although the laboratory is still in its original location, the inside has been completely changed.Not only is the area much larger, but there are also some more equipment and machines that Kuramayan has no use for.

The computer host was replaced by a model as large as a wardrobe, with five monitors placed side by side.

In the large culture chamber in the middle of the laboratory, a black object resembling a sea anemone was soaked in a green suspicious liquid that was constantly bubbling.

This is exactly the "Earth Resentment Yu" that was separated from Na Jiaodu.

According to Orochimaru, this [Earthly Enemy Yu] itself should also be some kind of active organism.

After being forcibly stripped from Kakuzu, the activity of [Earthly Resentment Yu] was in a very sluggish state, so he could only put it in this large training warehouse and let it cultivate for a few days.

Of course, after its activity is slightly restored, Orochimaru will still seal it and carry it with him.

After all, [Earthly Resentment Yu] is a secret treasure that can give people immortality. Now, for Orochimaru, this is something equivalent to his wealth and life.

"Everything has been debugged and completed, Yanjun, please don't doubt my professionalism."

Orochimaru was sitting on the newly purchased rotatable armchair. When he heard Kuramahiko's question, he stopped what he was doing, controlled the direction of the armchair, and faced Kuramahiko with a smile on his face.

Recently, he was in a very happy mood because he had received a large amount of scientific research funds and treasures like [Earthly Resentment Yu].

He is no longer as afraid of Kurama Yan who entrusted these things to him.After all, Kuramayan's threat only existed in his imagination, while the benefits he received were real.

I have been pursuing the road to eternal life for many years but could not see the path. After working with Kurama Yan, I not only saw the end point directly, but also explored many other routes with extremely high possibilities.

"What is that?" Kuramayan noticed that Orochimaru was holding a test tube filled with clear liquid.

"You should know that after chakra leaves the body, if there is no 'jutsu' as a carrier, it will quickly dissipate in the air."

Orochimaru shook the test tube in his hand and explained with a smile: "And this solution called chakra reagent is a special liquid that can dissolve the human body's chakra into it. Without this reagent, it is impossible to study chakra It’s impossible to talk about characteristics.”

"So that's what happened." Kurama Yan nodded, and then he understood.

Orochimaru stood up from his seat and walked to Kuramahiko and handed him the test tube: "Just inject your chakra into the test tube. When the liquid turns dark blue, it proves that the chakra contained in it is Carats are at their limit.”

"After that, I will use instruments specially designed to detect the properties of chakra to conduct a preliminary exploration of the secrets contained in your chakra. Of course, this will take a little time."

"How long will it take?" Kuramayan asked, watching the reagent in the test tube in his hand gradually turn into dark blue.

"It will take at least three to five days." Orochimaru replied.

Then he took out three more test tubes and handed them to Kurama Yan, saying, "One is not enough. You need to keep several more samples."

"Then I'll come back in five days."

Kurama Yan filled the remaining test tubes with chakra one by one and left.

……

"Orochimaru needs to analyze my chakra, so I can't be too decadent in my free time these days. I must use it and practice well."

In the forest of death, Kurama Yan made a decision silently in his heart while leaping forward on the big branches in the direction of the village.

"From today on, I won't go to the card house to play cards."
