Hyun Yu stretched out his hand and pressed it lightly on the mechanism, then tried to twist the palm-sized round stone plate.

In the original theatrical version, this mechanism was destroyed, causing the entire seal to be forcibly lifted, and the ore vein directly lost control and began to run wild.

Xuan Yu is trying to see if he can activate this mechanism and find the Grell Vein, which will be his only chance.

Click.

"Opened?!" Hyun Yu showed a hint of surprise on his face, and immediately turned his head to look.

Buzzing!

I saw that the eight arc-shaped pillars that supported the Sealing Room were all moving backwards, and the top of the Sealing Room was slowly lowering a circular platform.

"That's it, Greer's vein?"

Xuan Yu looked up, and the hole formed after descending from the circular platform could clearly see the scene above.

The pale green veins of Grell were directly above the Sealed Chamber, like an upside-down lake.

In the middle of the vein, a large cone-shaped stone pillar stood right in the center of the Sealing Chamber.

Xuan Yu then walked down to the circular platform, looked at the three items placed on the platform, and his heart suddenly burst into ecstasy.

"This is the Stone of Greel! And there are actually three. ”

Hyun Woo reached out and gently picked up a Grell Stone that was placed on the platform.

The dark blue stone with an oval shape like a jewel looks beautiful as if it were filled with the sea.

The Stone of Grell is the product of condensing and solidifying the liquid veins of Greer.

In the past, the ancient empire relied on the Grell Stone extracted from the Grell vein to establish a civilization beyond the era.

But in the end, it was also because of this force that led to the outbreak of war, and the ancient empire also perished.

Not only that, but the Stone of Grell is also known as the source of life, and is made of very pure chakra.

Xuan Yu was thinking that if he could successfully fuse the energy of the Grell Stone, then his injuries and fatigue would also be alleviated.

"The enemy should have searched for my traces in the ruins, and I can't hide here all the time, if I don't starve to death, I will die of thirst, so I can only gamble."

Xuan Yu knew very well that now his situation was no longer a way out, and if he wanted to get out of here alive, he had to obtain the power of the Grell Stone.

Xuan Yu looked at him for a moment, and then he no longer hesitated, put his thumb to his mouth and bit hard, and the wound suddenly flowed blood.

Then, Xuan Yu began to depict the sealing technique on his naked stomach, and what he portrayed was the four-elephant sealing technique.

In the months when he escaped a catastrophe and returned to Konoha with Xiao Nan, Hyun Woo planned to find a way to find information about other theatrical things during the war, so he also made some preparations.

The Four Elephant Seals were specially asked by Tsunade to learn in order to test one of his ideas.

After the marriage between the Thousand Hands Clan and the Vortex Clan, there are also many sealing techniques of the Vortex Clan.

Tsunade did not refuse his request, and directly lent him the record scroll of the Four Elephant Seal.

In fact, the sealing technique, except for the sealing technique of the four elephants and the ghoul sealing, which all end up together, all others need to be temporarily portrayed and sealed.

Therefore, it is difficult to play a role in real battles, otherwise according to the nature of the sealing technique that can seal the chakra, it would be good to seal the enemy directly, simple and rude.

Through those months of study, Xuan Yu also barely mastered one of the techniques of the Four Elephant Seal, that is, the fusion sealing technique of the Four Elephant Seal.

As for the other suppression sealing technique of the Four Elephant Seal, Xuan Yu had not yet fully mastered it.

The Bagua Seal, which is stronger than the Four Elephant Seal, is composed of two Four Elephant Sealing Techniques superimposed and improved.

The two techniques of the Four Elephant Seals are the Fusion Sealing Technique and the Suppression Sealing Technique.

In the original books, the fusion sealing technique was used to allow Naruto to fuse and use the Nine-Tails' chakra.

The suppression sealing technique is used to suppress the chakra of the Nine-Tails, thus making the Nine-Tails more stable.

This is equivalent to installing an energy storage device in Naruto's body that can constantly supply him with chakra.

It's just that the extracted nine-tailed chakra is not pure, so it will affect the will of the person.

After Xuan Yu figured this out, he couldn't help but wonder if the huge pure chakras that appeared in the theater version could also be sealed in the human body.

Tailed beasts are also made up of chakras, so since the sealing technique can seal conscious tailed beasts, why can't he try to seal the unconscious huge chakras.

But what Xuan Yu didn't expect was that it wouldn't be long before he was forced to carry out this experiment now.

After all, this is just a conjecture, Xuan Yu originally wanted to prepare more thoroughly and try again, but now he doesn't have this time.

"I can't care so much, let's die!"

At this time, Xuan Yu had already finished carving the sealing technique, which was a vortex, and the spiral line that formed the vortex was directly above the navel, constantly rotating and the final end pointed to the navel position.

In addition to the vortex technique, there are also some special lines depicted around the entire vortex.

Then, Xuan Yu picked up a Grell Stone with his other hand and slowly approached the sealing technique.

"Four Elephant Seals!"

Immediately after, Xuan Yu pressed the Grell Stone on the seal with one palm, and let out a soft snort in his mouth.

With the activation of the sealing technique, the swirling spiral pattern began to rotate counterclockwise, and Xuanyu's navel directly turned into a pitch-black hole.

The Stone of Grell in his hand, under his gaze, began to sink into the mouth of the pitch-black hole, drawing a few ripples.

"Hmph..."

Just when Xuan Yu thought he had succeeded, a strong force spread violently from the sealing technique to his whole body, making him can't help but scream in pain.

"Damn... It seems that even the unconscious chakra has an energy impact..."

Xuan Yu frowned, still suppressing the energy fluctuations emitted by the Grell Stone.

At this moment, the other two Grell Stones, which were originally placed aside, suddenly moved and directly crashed into the Four Elephant Seals together.

"What?!"

Xuan Yu was terrified inexplicably, and there was no time to stop it, and the energy brought by the three Grell Stones directly impacted Xuan Yu's seal.

The intense pain instantly spread to his whole body, causing Xuan Yu to kneel directly to the ground, his expression became extremely hideous, and he could only grit his teeth and continue to bear it.

But at the same time as the pain, Xuan Yu also felt that the injuries on his body seemed to be gradually healing, and the fatigue had been completely replaced by pain.
