Kakashi walked out of Mizuki's cell, beckoned to the shadows not far away, and said, "After the punishment of the Wind God and Thunder God is over, you will add an extra bowl of Ichiraku Ramen to the Wind God and Thunder God every day in the future, so that they should be able to stop." ”

The shadow was a little confused when he heard this, but Kakashi said so, so naturally he wouldn't object.

"Yes! Your Excellency. ”

"Alright, let's go down." Kakashi said.

The dark part heard the words and went down obediently.

Kakashi said to Hinata Tiger again, "Little Tiger, did you also find the laboratory abandoned by Orochimaru about the previous capture of Mizuki?" ”

"Yes, Minister."

"Where are the lab materials?" Kakashi's eyes narrowed, and he asked.

If Kakashi was asking someone else, he probably didn't know.

But it was Hinata Tiger who was responsible for this matter in the first place, so he knew it very well.

"In the archives of the Dark Side."

"Is it there? Follow me. Kakashi said.

"Yes, Minister."

Hinata Tiger said, following behind Kakashi.

The archives of the dark department seal a lot of information from the dark department.

Except for the Hokage, only the minister of the dark department has the right to transfer and watch at will.

Others, without permission, are not allowed to get involved.

Even the Elders.

The two turned left and right, and soon came to the door of a large gate.

"Your Excellency, the information is inside."

Hinata Tiger said, turning his head to the other side to avoid suspicion.

Kakashi looked at the heavy gate, his hands sealed, and pressed against the rune in the doorway.

The door is not opened with a key, but by means of a chakra seal.

There was a click, and the door opened.

"Your Excellency, the pile of materials was placed on the tenth shelf, the third line and the seventh file." Hinata Tiger said.

"Okay, I'll go in and take a look, you're here to watch." Kakashi said.

"Yes! Your Excellency. ”

Hinata Tiger stood meticulously at the door, and Kakashi walked into the archives.

"It's been a long time since I've been here." Kakashi chuckled.

The last time he came to the archives was to investigate the cause of his father's death.

Nowadays, time has changed, and it is really very different.

"Mizuki's body does have the phenomenon of using his life force to increase his strength and then drying up. In this way, Orochimaru should have studied how to extract life force. Perhaps it was during the study of intercolumnar cells that the results were obtained. ”

Kakashi secretly said in his heart, this is also the reason why he wanted to confirm the situation in Mizuki's body before.

According to Kakashi's observation just now, the reason why Mizuki's life force in his body disappeared was because he was forcibly consumed by a drug.

Because of this, even Tsunade couldn't be cured and restored to its original state.

If you want to talk about medical ninjutsu, Orochimaru naturally can't catch up with Tsunade.

But when it comes to experiments, ten Tsunade can't compare to Orochimaru.

The father of Hokage science, Orochimaru. No one was convinced.

"If the curse mark on Mizuki's body is also strange. It stands to reason that Mizuki's talent is so poor, Orochimaru definitely doesn't look down on him, so how can he give him a curse mark? Even the most superficial of spell marks. ”

Kakashi couldn't figure it out, so he came here to find information. 、

Following the direction that Hinata Tiger said, Kakashi quickly got what he wanted.

There is a layer of dust on the file bag.

After all, it has been here for nearly two years, and it is normal to get dusty.

Sweeping the dust off the surface, Kakashi took out the materials inside.

Some of these materials were obtained by Mizuki from the abandoned laboratory of Orochimaru, and some of them were discovered by the dark department in that laboratory.

The other part is Tsunade's summary of the potion taken by this Mizuki.

The more Kakashi looked, the tighter his brow furrowed.

After a long time, Kakashi put down the scroll and fell into deep thought.

"Sure enough, Orochimaru once studied the issue of life force potential."

It is recorded in the scroll that in the laboratory, a note was found that Orochimaru did not have time to take with him.

It clearly records one of Orochimaru's failed experiments.

After obtaining the intercolumnar cells, Orochimaru discovered the huge vitality in the intercolumnar cells.

And it is this vitality that makes the Thousand Hands Pillar have an immortal body that is different from ordinary people.

After Orochimaru came to this conclusion, he was so excited that he even put aside the experiment of intercolumn cells and conducted research on life force.

But it's a pity that after Orochimaru's research, he found that life force is extremely difficult to control.

The most intuitive display of vitality is the intercolumnar cell.

Because no one's vitality is greater than that of the Thousand Hands Pillar.

And in the course of this experiment, there was a failure of the experiment, that is, the curse mark of the Great Snake Pill Flow.

It was also from this experiment that Orochimaru got the inspiration for the spell mark.

The curse mark was originally created by Orochimaru to alleviate the problem of life force consumption.

But after creating it, Orochimaru found that the immortal chakra possessed by the spell mark could actually slightly alleviate the consumption of life force, but if it was to completely cancel it out, I am afraid it would be a little short.

And the Immortal Chakra is the highest level of energy that Orochimaru can master.

In Orochimaru's view, natural energy and life force are two very similar things, and there is the possibility of canceling each other.

However, the immortal chakra formed by the natural energy mastered by Orochimaru was still a little lower than the level of life force.

So in desperation, Orochimaru gave up this idea.

However, Orochimaru's experiment was not completely fruitless, after all, there was still a curse mark.

However, when Kakashi saw this, he was shocked.

Vitality?

Creating life?

Isn't that yin and yang?

It's no wonder that the Great Snake Pill will fail, although the Immortal Chakra is one level higher than the ordinary Chakra.

But compared to Yin and Yang, it is still a little worse.

"I didn't expect that Orochimaru had also studied Yin Yang Dun, and he really deserved to be a genius who studied forbidden arts. It's really curious that there is something else in this world that he hasn't studied. It's a pity that it hasn't touched that field yet. ”

Kakashi muttered, then put the scroll back on the shelf.

But at this moment, Kakashi's heart moved.

"Yin and Yang? Immortal Chakra? By the way, I remember that the Slug Immortal once said that the fusion of the three major immortal arts will produce terrifying power, isn't it ......?"

Kakashi suddenly sounded his own silver-white senjutsu chakra.

"No, no, Yin and Yang are things that exert the power of spirit and body to the extreme, and it has nothing to do with natural energy."

Kakashi made a self-denial.

"What went wrong?"
