Trying to use the Dragon Vein as a chakra battery to charge the Yin Seal did not seem so simple. There would be significant risks.
Seiryū narrowed his eyes.
The reason he was interested in the Dragon Vein was to try using its chakra to charge the Yin Seal and accelerate its storage speed, keeping it as a trump card.
Now that he had sensed that the Dragon Vein chakra contained natural energy, he could not attempt it recklessly.
He did not want to experience being invaded by natural energy again.
Unless Seiryū modified his body, or mastered Sage Mode, or at the very least possessed the special traits of the Rōran royal line, recklessly absorbing Dragon Vein chakra would be very dangerous.
Moreover, the Dragon Vein belonged to Rōran.
It would not be right for him to take it by force.
He was not a bandit. At his core, he was a kind person.
He would not do something so disgraceful.
"I'll go shut down the Dragon Vein. Wait here. Only the Rōran queen can control it. If others enter, it may cause the Dragon Vein to go berserk."
Sāra spoke to Seiryū.
She then ran toward the central platform.
"The Rōran royal line should have some kind of special trait. Perhaps an ancestor once adapted to the Dragon Vein chakra, and this trait has been passed down through generations?"
Watching Sāra's back, Seiryū stroked his chin and muttered.
This was not hard to understand.
Just like bloodline limits related to the body, they were passed down through bloodlines, forming clans.
Uchiha, Hyuga, Senju, Uzumaki and others were like this.
Of course, some bloodline limits could be obtained through training.
But those were elemental transformations and did not involve bodily traits.
The Rōran royal line should be similar to bloodline clans.
At some point, a queen adapted to the Dragon Vein chakra and gained control over it.
This special trait was then passed down through generations.
"Forget it. I've already built a good relationship with Sāra. I call her big sister, she calls me little brother. There will be chances in the future."
Seiryū shook his head and let out a breath.
"If it comes down to it, I'll just buy it when I have money. I am her savior after all. If she doesn't repay me with herself, she can use other methods. Maybe it can even prevent this country's downfall."
There would still be opportunities in the future.
After all, he had saved her life.
If not repaying with herself, then she could repay in other ways.
In the original story, Rōran eventually became ruins, existing in name only.
Perhaps with his involvement, that outcome could be avoided.
"Next... I'll complete the system mission, and also take a look at Rasenshuriken, to see if I can understand its technique..."
"Shadow Clone Jutsu!"
He created a clone to stay here in case of unexpected situations and to protect Sāra.
Seiryū's main body rushed toward the source of the battle.
The battle there had not subsided. Instead, it had grown more intense and was getting closer.
The ceiling, no, the ground above suddenly shattered.
The massive puppet giant crashed down along with falling debris, slamming heavily onto the ground.
With a loud rumble, a huge crater formed.
"Hahaha, it's useless! No matter what attacks you use, you can't defeat me! My power is endless. As long as the Dragon Vein is not shut down, I will keep recovering!"
The puppet giant waved its arm, dispersing the dust.
Anrokuzan's arrogant laughter echoed through the underground space, shaking loose falling debris.
"All of you, die, you damned Konoha shinobi!"
Crackle crackle!
Dragon Vein chakra surged under Anrokuzan's control, the particle-like chakra turning into purple lightning that poured into his body.
His strength grew even greater, reaching Kage level.
"Dragon Vein Super Great Dragon Fire Technique!"
With a low shout, purple chakra gathered at the cannon on the puppet giant's abdomen.
It turned into a purple beam and blasted toward Tsunade and the others who were chasing him.
Boom boom boom!
The charged attack carried terrifying power, and upon impact, it triggered a massive explosion.
The entire space trembled, and more rocks fell from above.
"Ahhh!"
Amid the scream, a figure was blasted out of the smoke.
It was Naruto.
"Bakudō #4: Hainawa."
Seiryū acted instantly, forming hand seals and casting a golden rope of light, pulling Naruto back from midair.
"Huh, it's Sage Seiryū? Thanks a lot!"
Seeing that Seiryū had saved him, Naruto expressed his gratitude.
Then he looked at Anrokuzan, his expression turning serious, "This guy is really strong. His chakra feels endless, and he keeps recovering. How are we supposed to defeat someone like this?"
Endless chakra and rapid regeneration made him extremely troublesome.
Seiryū stood with his hands behind his back and said calmly, "Young man, why not use your Rasenshuriken, the one infused with wind nature transformation?"
"Wind Release has powerful cutting properties. It might be effective. I also want to see it."
This was the perfect opportunity.
To have Naruto use Rasenshuriken.
As for its side effects that could harm the user, with both him and Tsunade as medical ninja, it could be healed quickly.
"Huh? Ah? I forgot about that!"
Naruto slapped his forehead.
But thinking of another issue, he said, "But this jutsu has a huge attack range. I'm worried it might affect others!"
Seiryū waved his hand, "Don't worry. Minato knows Flying Thunder God Technique. He can instantly move others to a safe place. It won't affect them."
"Flying Thunder God Technique?"
Naruto looked confused, clearly not knowing this jutsu.
But hearing Seiryū speak with such confidence, he did not hesitate, "Alright then. I did promise to show it to you once!"
He created two shadow clones.
Naruto began performing the technique.
Buzz buzz buzz...
The main body gathered chakra in his palm, the left clone infused wind nature transformation, and the other clone maintained stability.
Each had a clear role.
As the buzzing sound grew louder and sharper, Rasenshuriken gradually took shape.
The wind intensified, kicking up dust around them.
Holding the Rasenshuriken above his right hand, Naruto smiled, "This is Wind Release: Rasenshuriken. It's my strongest jutsu right now!"
So that was it.
Watching Naruto perform the Rasenshuriken, Seiryū understood the key points.
The amount of wind nature chakra was crucial. Too much and it would explode, too little and it would lose power or fail to form.
A balance had to be maintained between Rasengan and wind nature transformation. As long as it could be controlled and stabilized, the Rasenshuriken could be formed.
It did not seem that difficult.
As someone who transmigrated, Seiryū already understood the principle behind Rasenshuriken.
Its difficulty, like Rasengan, lay in control and maintaining stability.
This was not a problem for him.
What he wanted to understand was the technique.
Balance, control, stability, and the amount of wind chakra infused were the keys to forming Rasenshuriken.
Seiryū could develop it himself given time.
He did not think he would fail.
But as always, if he could get it for free, he preferred that.
And he did manage to get it for free.
By observing Naruto's process, timing, and method
Seiryū had already formed a rough understanding of how to maintain the balance of Rasenshuriken.
Perhaps after a few or a dozen attempts, he could successfully use it.
This saved him a lot of time.
Honestly, getting it for free really felt great.
