In the Hokage's office, Sarutobi Hizashi secretly summoned Orochimaru.

"I have two tasks for you, Orochimaru." Ape Fei Ri Slash's tone was serious.

Orochimaru asked calmly, "What mission?"

"Use the art of reincarnation in the Dirt to summon the Silver Horn." Ape Fei Ri said with a solemn expression, "There is no one in the village anymore, and compared to other countries, Konoha has fallen into a weakness, so it is necessary to extract the nine-tailed chakra in the silver horn body and recreate the human pillar power."

"I see." Orochimaru's face was calm after hearing this, and he didn't seem surprised by this.

He then asked, "What about the second mission?"

Ape Feiri frowned, and said in a deep voice: "The corpse of the first adult was sealed by Kushina, I hope you can crack it, it is necessary to continue the Mu Dun experiment, the current village needs the power of Mu Dun."

[In view of the general environment, Orochimaru raised his eyebrows, it was actually this, it seems that the existence of Uzumaki Yurobe and Kushina has put a lot of pressure on the village, and even the method of forcibly breaking the seal has been proposed.

This is not the kind of sneaky behavior of Danzo, but an order from the three generations of Hokage himself.

"But Tsunade's ......," Orochimaru's face hesitated.

"At that time, I will explain to her, if the research results are really achieved, let the rope tree experience it first, and when he awakens Mu Dun, I believe Tsunade will not pursue this matter."

"I see." Orochimaru bowed slightly, the rope tree was his disciple, and he was naturally happy to become stronger.

Then he changed his words, "But I'm not sure I'll be able to break the seal left by Kushina."

The Uzumaki clan already has the strongest sealing technique in the ninja world, and coupled with the strange power that Kushina has used, Orochimaru really can't guarantee it.

Hearing the disciple's modesty, Ape Fei Ri shook his head and affirmed, "I believe you have such a talent."

Afterwards, Orochimaru said goodbye to Sarutobi.

After leaving the Hokage Building, thinking of the various breaths he had just sensed underground, Orochimaru was silent.

The defense of the dark base has become tighter, and it seems that the root has been absorbed by the teacher.

"But how did Danzou die? Why can't I hear any news of the battle?"

After taking over the task, Orochimaru did not immediately go to the laboratory, but returned to his home.

He pushed the door open, and the rope tree was already waiting inside.

"Orochimaru-sensei."

"Well, after today, you're going to be a leading teacher." Orochimaru changed his voice and asked, "How is Tsunade's mood lately?"

Since that incident, Tsunade's mood has not been high, and he has even gone to Konoha Hospital a lot less.

Fortunately, this is not a time of war, and there are not a large number of injuries that need to be treated.

Rope tree shrugged his shoulders and said helplessly, "I am immersed in research every day, occasionally medical ninjutsu, and most of them are looking at the secret techniques left by the family and the like."

"The elder sister seems to be very interested in the immortal inheritance left by her grandfather."

Hearing this, Orochimaru's eyes froze, as the contractor of the Dragon Land Cave, he was no stranger to immortal arts.

For Orochimaru, natural energy, a power that is different from chakra, will naturally not be let go by him. ….

However, due to the lack of a way to feel and absorb the energy of nature, the corresponding experiments have not yet begun, and are only in a state of planning.

The Dragon Earth Cave actually has an immortal mode cultivation method, but it is too rough, and the White Snake Immortal personally injects natural energy into the contractor's body.

If you succeed, you live, and if you fail, you die.

How could such a way be accepted by Orochimaru, who believes in science!

Therefore, he never proposed the idea of cultivating immortal arts to the White Snake Immortals.

"Is the first Hokage's senjutsu inheritance?" Orochimaru thought in his heart.

……

Wet bone forest.

Tsunade came here again, just to try to master the immortal art inherited from the Wet Bone Forest.

"Alas, it's so hard to ......."

Get out of the state of cultivation

Later, Tsunade let out a long sigh, his face full of sorrow.

Following the instructions of the living slug, she completed every step without feeling the slightest natural energy at all.

Tsunade raised his hand and tapped his forehead, and said in distress:

"How did Grandfather succeed in cultivating? He didn't leave a detailed record, just a few words."

Hearing her question, the living slug fell into deep thought and began to recall the events of decades ago.

"The Thousand Hand Pillars did not cultivate the immortal art of the Wet Bone Forest, he just absorbed the natural energy here, and naturally entered the immortal mode.

Although he signed a contract with me, he barely summoned me, and my healing power is not comparable to his self-healing ability."

As he spoke, a flash of memory flashed in the slug's eyes.

That scene left a deep impression on her!

Tsunade sat down on the ground and couldn't help but complain:

"I see, no wonder there is no record left."

Although this outcome had been expected, her mood was still slightly low.

Seeing Kushina's strength surpass him step by step, Tsunade was also unwilling in his heart, let alone that stronger man.

It's obviously a younger sister who grew up watching from a young age, but her strength surpasses herself, and it's hard to describe.

If she can't master the immortal arts, the sky she sees in the future will become narrow.

Looking at the scenery in the distance, Tsunade's words unconsciously came to Kushina's mind.

"The country of vortex, there may be a solution."

Suddenly, she saw the mountain peaks in the distance in a daze, and her eyebrows were full of doubts.

"Slug, isn't that mountain much bigger? That didn't seem like the last time I saw you?"

"It was left by Lord Xia Wu, and it was used to seal the Nine-Tails."

The live slug explained slowly.

"What?"

Tsunade was suddenly surprised, he didn't expect Xia Wu to have such strength, no wonder Kushina was able to control the Chakra of the Nine-Tails so early.

"So how can it keep getting bigger?"

"Because Lord Xia Wu's will to stay in the seal has not dissipated, and he is constantly absorbing natural energy, the mountain will slowly become larger.

Recently, though, the rate at which it absorbs natural energy has slowed, and it seems to be undergoing something in the shadows."

The live slug replied slowly.

A seal left behind can absorb natural energy, and I can't do it at all.

Thinking of this, Tsunade's mood instantly dropped, and he squatted next to him to draw a circle.

Seeing her like this, the living slug comforted:

"Tsunade, you can go to Lord Xia Wu to learn how to master natural energy, he has an extremely delicate grasp of it."

"When he came to the Wet Bone Forest and asked me to swallow him, it startled me, but he quickly felt the natural energy."

"And unlike your grandfather, Natsutake-sama did not fuse natural energy with chakra, but used it to strengthen the body, and he is a very remarkable person."

Listening to the narration of the living slugs and looking at the mountain that had been sealed, Tsunade made a decision.

Inaction is in the world
