The reason why the Samurai of Roran can refine Ryumyaku Chakra is because the terrain where their country lives, there is an unknown force that is changing their within-the-body Chakra.
Originally at first, the Chakra they extracted was also ordinary, but under the ebbing of time, their constitution was changed, so that the refined Chakra was converted into Ryumyaku Chakra.
After Queen of Roran discovered this problem, she naturally found the problem, and then found that at the bottom of the castle, there was something like an altar, and a wellhead in the center of the altar exuded unknown power. Source.
Because this unknown power not at all brought casualties to the building, but it also strengthened the strength of the Roland Samurai, so the queen did not at all how to do it, but sent heavy soldiers to guard.
It's a pity that such a secret thing, even if one knows it, even if more people know it, the spread of this news is getting faster and faster, so that because of the relationship of Ryumyaku, it is involved in the war.
During the war, every country, no matter how big or small, had only one purpose, that is to open up the territory and strengthen the strength of his country. After the news of Roran Ryumyaku was spread to the outside world, it attracted a lot of Ninja Village peeping. There is also Hidden Sand Village in Five-Great Ninja Villages.
Although Roran's Samurai owned Ryumyaku Chakra, they still lost to Ninjutsu. Eventually, the ancient country of Roran disappeared at the end of Third Shinobi World War Early-Stage. Finally, although Ryumyaku was discovered by the people of Hidden Sand Village, it could not disappear be transferred.
They did n't even investigate what Ryumyaku was, so there was a treasure mountain and they could n't use it. They could only leave a part of Ninja in Hidden Sand Village here at Refining Chakra, so much so that in Third Shinobi World War Middle-Stage, Hidden Sand The strength of Village suddenly increased a lot.
And other Ninja Villages are not idiots. After seeing the improvement of Hidden Sand Village strength, they will not let Ryumyaku go, but Ryumyaku is too far away from their village and has no advantage of Hidden Sand Village.
Fortunately, Ryumyaku was finally used by Konoha's Yellow Flash, Namikaze Minato Imprison, and used Uzumaki Clan's powerful Sealing Jutsu. So far, Ryumyaku's existence was gradually forgotten by outsiders.
"It should be right here." Ash came to a place in the desert, looked at the endless sand, but Ash felt a strange force attracting his within-the-body's blood.
"Ding~!"
"Unknown powers are discovered in the underground 700 meters away from the host."
"700 fans?"
"It should be Ryumyaku." The sudden sound of the system hint made Ash startle. Now, except for the necessary circumstances, the system will not take the initiative unless he takes the initiative to summon the system.
I looked at a virtual screen map that only I could see. Ash followed the red punctuation. As the distance got closer and closer, the blood of Ash within-the-body began to quickly rise within-the-body flow, The 4 infinite gems in the soul also began to rotate irregularly.
"Don't you say." Thinking of a certain possibility, Ash was excited and his body began to sneak into Ground. After living in Five-Attributes, Ash exchanged for the Ninjutsu Daquan. Earth-Style Ninjutsu can be said that no one is more proficient than him.
"Scratch."
"Peng!"
At 2 1000 more then 300 meters underground, Ash fell from the mud to a dark place, and this is also the center point on the ground that emits unknown energy.
"Ding~!"
"When discovering energy gems, holders can possess super-strong energy recovery speed, which can reach almost unlimited!"
"As expected, didn't expect will be found here." After hearing the system prompt, Ash almost yelled in excitement, although there is no god gem, so other gems can't be played even if they are merged by him. Power , but since Power Gem is weakened from infinite power to only a few times increase, presumably the energy gem will not be weakened too much.
"Sharingan." Resisting the excitement, Ash opened Sharingan and kept approaching the energy gem.
"Hahahahaha, found it." Ash unable to bear smiled at the jewel wrapped in red energy in front of him, then impatient integrated the energy gem into within-the-body.
"bang! !!"
"This recovery speed." After the fusion of energy gems, Ash suddenly felt that within-the-body's Chakra was recovering at a rate of 3 or 4 times as fast as before. If you know that Ash is already in Senju Bloodline, recovery is enough. It's fast, add 3 4 times, it's scary to think about it.
"I'm afraid that Roran's Samurai was affected by the power emitted by the energy gem, but they never thought that it would be a gem."
After returning to Ground, Ash really didn't expect that this time it would be so smooth. Since he left Hidden Rain Village, it took less than 3 hours to get it, giving him an unrealistic feeling.
"Fire-Style Great Fire Annihilation." Against the desert, Ash hand seals his hands, takes a deep breath, and then Spit Up a flame in the range of 4 50 meters.
"Rumble." In the desert that was already hot, the flames increased even more. The sand in the distance was roasted by Ash's Great Fire Annihilation.
"Worthy-of is an energy gem. Even if it is because of the divine gemstone, it can't get me infinite energy, but this kind of resilience, I think even Kaguya Ji can't beat me.
Feeling the Chakra recovered within-the-body instantly, Ash unconsciously smiled, Great Fire Annihilation but Fire-Style Ninjutsu of comparable with S-Rank, the Chakra consumed is not to be underestimated, but recovered in split second , Showing the horror of the energy gem.
"En?" At this moment, Ash suddenly found that there was a 3 fork kunai inserted in the ground just now, but it was covered by the sand so that he did not find it just now. It was only exposed after being swept by the Great Fire Annihilation.
