Naruto Uzumaki: Born Evil

Looking at the key to open the seal of the Grayer Mine in front of him.

Naruto did not hesitate at all.

According to the method in the Grayer Book, he directly opened the seal that had existed for who knows how many years.

When the seal was opened, Naruto could already feel a strong life energy suddenly escaping from the mural in front of him.

In just a few breaths, the life energy escaping from the mural had completely filled the entire underground palace.

Even Naruto, who possessed the Uzumaki bloodline and the Nine-Tails Chakra, could not help but feel extremely shocked by this life energy.

"Is this the power that is said to be able to conquer the world?"

"Just a trace of life energy that has leaked out is no weaker than the vitality of the Uzumaki clan."

Naruto could not help but sigh, and then continued to observe the changes in the mural in front of him.

In the blink of an eye, the wall of the mural, which originally looked extremely dark and recorded the destruction of the empire, began to fall off without any warning.

As the fine stone chips and dust fell, the real appearance of the interior of the mural gradually appeared in front of Naruto.

"This mural is really abstract."

Naruto couldn't help but complain again. He didn't have much artistic talent.

Without the description of the Book of Grayer, he could only see that the mural was two people holding hands.

But he didn't need to understand anything, because the mural soon showed new changes.

The mural, which was originally tightly closed, cracked in the middle, revealing the glittering light inside.

Soon, the crack opened wider and wider, and the two separated stone walls moved to both sides.

Finally.

After the mural was separated, the crystal stone embedded in the mountain, which was as crystal clear as jade and emitted a light green halo, gradually appeared, and inside the crystal, there was a fluid energy with mist like spring water.

In an instant, the dim palace was illuminated.

The vein of blue light illuminated the dark palace. Naruto could feel that the life energy in the palace was a little more viscous. Inexplicably, Naruto felt that his body was sensing a little throbbing from the energy inside.

His body was eager to absorb the energy inside.

This sudden situation surprised Naruto. As for his current physique, apart from the amount of chakra, just from the perspective of vitality, he was already very close to the original Senju Hashirama.

As for chakra, he had no choice. This thing was born and it was basically difficult to change.

This also showed that Naruto's physique had not yet reached the strength of a sage body.

But——

"Perhaps, this Grayer vein can make me a complete sage body?"

Naruto slowly approached the exposed emerald green crystal vein and placed his right palm on it.

As the cold feeling came, Naruto also began to sense the true power contained in the vein.

As Naruto perceived, a hint of thought flashed in his eyes.

The results of the Grayer ore vein were similar to those obtained from the girl in prison. This was indeed a mineral that stored terrifying life energy.

In addition to the extremely pure life energy, it also contained a natural energy of extremely high purity.

Naruto could feel that if he wanted to use the power of this ore thoroughly, the natural energy inside would definitely be activated, and he might become a half-human, half-beast monster like Chougo.

What surprised him was that although there was natural energy and life energy in this ore vein, there was no chakra.

Because of this, even people without chakra could gain enough power after obtaining the Grayer Stone.

The fall of this ancient empire was many years ago, which was a period even more ancient than Kaguya Otsutsuki.

And because this seal had existed since the fall of the ancient empire.

So the Grayer ore vein inside naturally had not been affected by the sacred tree.

It still retains the purest natural energy and life energy, which is considered the native power of the Naruto world.

However, this does not mean that the Gray Stone is useless to ninjas.

Now the ninja's chakra is closely related to the ninja's life energy. How much chakra you can extract,

Absorbing life energy is naturally equivalent to increasing the upper limit of chakra.

And this life energy can also promote the Yang escape power in his body and further improve his physique.

Thinking of this, Naruto no longer hesitated and began to extract the energy from the vein using the method recorded in the Gray Book.

In Gray BookThe book records in great detail the mining, smelting and use techniques of the Grayer ore vein, from the manufacture of crystal stones to various ways of use, almost every link is mentioned.

This method of extracting only energy is also very simple.

After a while, a large amount of liquid essence with a green halo overflowed from the Grayer ore vein, and it was like a stream of water pouring down from the crystal.

However, this liquefied energy essence did not fall directly to the ground.

Instead, after leaving the ore vein, it slowly floated up and flowed towards Naruto.

Then, Naruto was immersed in the liquid essence composed of life energy and natural energy.

Naruto was immersed in the liquid and subconsciously wanted to hold his breath, but the expression on his face quickly changed again, and then he tentatively let go of his breath.

"I can actually breathe in this liquid?!"

Naruto was quite surprised.

The natural energy and life energy flowing out of the Gray Stone surrounded him like a light green water ball, and was being absorbed by Naruto at an extremely slow speed.

At this moment, Naruto felt a surge of life energy rapidly pouring into his body.

"There is such a magical thing in the Ninja World?"

The Nine-Tails, who was lying in Naruto's sealed space, was also shocked by the sudden changes in Naruto's body.

"Yes, this is also a pleasant surprise."

Naruto responded to the Nine-Tails while absorbing the life essence in the vein.

But his voice at this time seemed very soft and slow, and the expression on his face was also very lazy.

The life energy in Naruto's body continued to increase, and this life energy was in his body.

This feeling of being immersed in the ocean of life made him feel so comfortable that he wanted to moan.

But this comfortable feeling did not last long.

As more life energy was absorbed, Naruto suddenly felt a swelling in his body.
