Shin'un's third skill had already been loaded a month ago.
According to Shin'un's original plan, it was a skill that could greatly increase Chakra reserves.
When Shin'un edits a skill, the skill name and effect he enters are as follows.
Skill Name: [ Qi Sea ]
Skill Effect: [A space capable of storing a massive amount of Chakra is created in the lower abdomen, based on acupoints and using Sealing Jutsu as pathways.]
[And after accommodating a certain amount of Chakra, it absorbs Natural Energy and converts it into Chakra until the space is full.]
Shin'un deliberated for a long time before finally deciding to use the word "massive" to describe the capacity of this space.
If the description is too small, then this so-called [ Qi Sea ] is completely meaningless; if the description is too large, Shin'un is afraid that the skill loading time will be dragged out too long, affecting the development of his strength.
The same applies to the setting where a certain amount of Chakra must be stored before it can absorb Natural Energy on its own.
In addition, Shin'un had some ulterior motives when editing this skill. He specifically pointed out in the skill effect that it should be based on the acupoints in the lower abdomen and the Sealing Jutsu that actually exist in the Shinobi World, in an attempt to open up a space that can store Chakra.
It is similar to the Yin Seal, but also has the ability to replenish Chakra independently.
In this way, by observing the spaces that truly exist in the acupoints of his lower abdomen, and with the addition of Sealing Jutsu, Shin'un might be able to create a second or third internal Qi Sea.
After all, there's no reason why he couldn't open up Qi Sea space in other parts of his body if the acupoints in his lower abdomen could do so.
"Boom!"
Several condensed wind clusters flew towards them, but Shin'un dodged them with a few leaps and they slammed directly into the ground.
Dust billowed, and several more holes appeared in the already ravaged grassland, revealing the dark brown soil beneath.
Seeing the pale-faced Hirakawa Shin'un, the Sunagakure Jonin smiled again, his attacks becoming increasingly swift, as if the scene of killing this Konoha genius was just around the corner.
"Phew~"
Having dodged another wind blade, Shen Cloud Ninja exhale a breath to relieve his fatigue.
Feeling his body gradually depleting, he glanced at the Sunagakure Chunin on the other side, who was unconsciously getting closer and closer to him as he released his Ninjutsu.
Feeling that the distance was just right, Shin'un decided to stop hiding.
Close your eyes slightly, focus your mind on the acupoints in your lower abdomen, and concentrate your spirit.
Faintly, a connection was made to a certain space, where the massive amount of Chakra stored by Shin'un was stirring restlessly.
Ever since the [ Qi Sea ] skill was fully loaded, Shin'un has been constantly channeling Chakra into it.
Over time, this accumulation, like a gentle stream, contains at least several dozen times the amount of Chakra Shin'un possesses.
Although it still doesn't have enough Chakra to activate the [ Qi Sea ]'s ability to absorb Natural Energy and replenish Chakra, the Chakra stored within should be more than enough for Shin'un to deal with the enemy before him.
With a thought, it was as if a switch had been flipped, and a large amount of Chakra obeyed his command, gushing out from the space in the acupoints below his abdomen, quickly replenishing all the Chakra that Shin'un had consumed.
The surge of countless Chakra even gave Shin'un the illusion that his lower abdomen was faintly burning.
"That's amazing!"
The abundance of Chakra caused Shin'un's pale face to disappear, gradually turning rosy.
Feeling the surging Chakra within his body, Shen Cloud Ninja but feel excited.
He looked up at the Sunagakure Chunin not far away, his eyes gleaming.
He was already eager to use Ninjutsu and experience the feeling of recklessly squandering Chakra.
What happened?
The Sand Ninja Village Jonin, still standing at a distance, felt a sudden unease when Jonin saw Shin'un's complexion return to normal.
"Just a moment ago, he was pale and his movements were becoming increasingly sluggish, clearly looking like he was about to run out of Chakra. How come he's like this now..."
Before he could think, seeing Hirakawa Shin'un, who had inexplicably regained his strength, looking at his Chunin comrade on the other side, the Sand Ninja Jonin issued a warning.
"Careful!"
Upon hearing their Jonin's warning, the Sunagakure also Chunin that something was amiss with Hirakawa Shin'un on the other side, and immediately became extremely vigilant, taking precautions.
Shin'un overheard the entire conversation between the two Sand Ninja, but paid no attention and simply smiled.
Raise both hands and begin Hand Seals.
The Hand Seals were formed in the blink of an eye, and Shin'un's Ninjutsu preparation was complete.
Lightning Release: Lightning Pillar!
As the Ninjutsu was completed, Shin'un stretched out one hand towards the Sand Ninja Chunin.
The next moment, Shin'un's aura surged, and his whole body emanated terrifying Chakra fluctuations. A thick pillar of lightning shot out from his outstretched palm.
The lightning pillar, a full two meters thick, was composed entirely of highly concentrated electric current. Its seamless appearance made it resemble a beam of light, and Chunin straight toward the Sunagakure Chunin not far away.
The lightning bolts were indestructible, piercing through everything in their path and shooting straight into the distance.
"Boom~~"
The thunderous sound gradually subsided, and Shin'un's Ninjutsu finally came to an end.
A few wisps of green smoke rose from his palm. Shin'un lowered his hand and looked in the direction he had attacked.
Starting from Shin'un's location, the grassland and bushes in front of him were all plowed away, revealing a layer of dark red lava that had not yet solidified. These traces became wider with distance, extending over a hundred meters away.
In this dense forest, a clearing was forcibly created.
Wow~~
Seeing this breathtaking scene, Shin'un couldn't help but exclaim in amazement.
Although this Lightning Release- style attack, resembling a pillar of light, was entirely developed by himself, this was the first time Shin'un had used it in actual combat due to its massive Chakra consumption.
It seems to be working well, and its power is quite surprising.
It's just that... its destructive power is so high that it's completely unnecessary to use it in normal-level ninja battles.
Feeling the Chakra within his body, Shin'un estimated the energy depleted by that attack.
"Goodness, just using a standard Lightning Release: Lightning Pillar once has already consumed so much energy."
"Twenty percent of the Chakra I painstakingly accumulated over a month has been used up in one go!"
"In total, a month's worth of Chakra is only enough for five uses of Lightning Pillar."
Shin'un shook his head; it seemed the day he could transform into a humanoid Ninjutsu turret was still a long way off.
"Ah!!!"
The wailing sounds coming from the other side caught Shin'un's attention.
Shin'un glanced sideways and saw the Sunagakure Chunin he had been aiming at.
The Chunin reacted quickly; after being reminded by the Jonin, he became more vigilant and immediately lunged to the side when he saw Shin'un raise his hand.
In the end, he actually managed to dodge half of Shin'un's Lightning Pillar.
As you can see, he was lying on the ground, howling and struggling, his body disappearing completely from the waist down.
All internal organs are exposed.
Such injuries essentially mean certain death.
