Seventh Reincarnation
Training Completed

Sitting cross-legged on a boulder, Ars closed his eyes and let the waterfall run over his body.

He was meditating in order to understand the essence of the technique he wanted to learn.

Idaten does not require eating, drinking, sleeping, breathing, excretion, and other physiological functions of humans. Plus, they are never tired and have unlimited energy.

He's been meditating here for over 10 years.

In order for Rin not to look for him, Ars had told him the meditation he wanted to do and he agreed.

Rin had also meditated on his mental training, so he did not mind Ars leaving for a few years and he focused on training Prontea.

"What is space?"

"Spaces are three-dimensional continuums containing position and direction. In classical physics, physical space is often understood in three linear dimensions."

"Modern physicists usually think of it, with time as part of the infinite four-dimensional continuum known as spacetime."

Ars still closed his eyes and talked to himself about the understanding he understood.

"The space itself is a form of energy. It can dominate and create life, and it can also dominate and annihilate life. When condensed into extremities, it would be distorted. It would hold everything inside like gravity, preventing anything from coming out."

"So it's like that... I understand now."

Opening his eyelids, a flash of inspiration was seen in Ars's eyes.

"Ha Ha Ha... I finally succeeded! After practicing 50 years of non-stop practice day and night, I have mastered the Infinite Technique (Limitless) of the Gojo Family."

He laughed out loud and was overjoyed because his hard work had paid off.

"After mastering the Infinite Technique, my understanding of space has increased drastically. Now it's not impossible to go to another world."

"Senior seemed to be in a good mood, did something good happen?"

Suddenly someone else interrupted Ars' dialogue.

"Oh, it turns out that it's Prontea. Long time no see, you never change."

Due to being too focused, Ars was unaware of the other party's arrival.

Prontea stood on the surface of the water and asked curiously: "Your training worked?"

"Yes." Yeah."

Ars stood up, snapped his finger, and a portal appeared in front of them.

"Wow, what is this?"

"Let's go in."

He gave no explanation and walked into the portal.

Prontea was not worried about something bad happening to her and entered the portal. Once past the other side of the portal, he is shocked to have appeared on the island where Rin kept the seal that sealed the Devil.

"It's great! Senior, I also want to learn this ability."

The location of the waterfall and the island is tens of thousands of kilometers, to be able to move just by flicking a finger, Prontea is very amazed.

"This is not worth mentioning, this is just a small ability of the Unbounded Technique."

Praised by his juniors, Ars felt somewhat embarrassed.

"There's still something better? I want to see!" Prontea said excitedly.

"Well, try to touch my hand." Ars raised his right hand.

"Like this... Eh?'

Following his senior direction, Prontea tried to touch Ars' hand, but he felt like there was a thin invisible layer blocking him.

"You can't touch me, can you? This is Infinity (Infinity). Infinite Techniques operate in the same way as convergent and divergent rows in mathematics. Infinity is the convergence of an immeasurable circuit, anything that approaches infinity will slow down and never reach the user."

Looking at the confused expression of Prontea, Ars simplified the explanation, even ordinary people could understand.

"Simply put, this technique takes a finite amount of space between two subjects and divides them in an unlimited number of ways. Although my hands look close, they are actually separated by an unlimited number."

This is the result of Ars training for more than 50 years in an effort to imitate the ability of Gojo Satoru.

Since he did not have the Six Eyes (Six Eyes) and the Infinite Technique formula inherited from the Gojo Family, he had to start from the ground up.

I don't know how many times he was killed by mistake while training. If it wasn't for his immortality, Ars wouldn't have dared to try to do this.

"You developed another strange ability, Ars."

I don't know when Rin appeared in front of the two of them.

"A, Rin. I brought the senior as you asked."

Prontea's body became stiff, turning around with a trembling body and his expression looked unnatural.

In fact, he respects and fears Rin after undergoing inhumane training.

Prontea lacks the fortitude of Ars, who remains indifferent despite having been mutilated by Rin every time training.

"You looking for me, Rin?" Ask Ars.

"En, let's test your combat strength first, how far you've progressed after meditation."

"I'm sorry then."

Seeing the battle about to begin, the wise Prontea went and watched from afar.

"You can attack first, Rin." Ars smiled confidently.

"Oh, you've become very brave."

Rin's figure disappears and in the blink of an eye he appears in front of Ars and hits him.

*BOOM*

The sound of an explosion, the shock wave of the blow blew the dust tens of meters behind Ars.

"Not hurt? Fascinating."

Rin finds the punch does not hit Ars, and instead hits an invisible thin barrier.

*BOOM BOOM*

A barrage of punches bombarded Ars, but he stood in his place without taking a single step back thanks to Infinity.

Each of Rin's punches will be divided infinitely this will slow down until it seems to stop completely.

"I have to ask senior to teach me!"

Watching in the distance, Prontea's eyes sparkled seeing Rin's attack ineffective.

Previously, he and Ars had always been beaten to death, this had left a deep trauma to him. Now that Ars has survived Rin's beating, Prontea is amazed.

"Not bad, you learned a good skill."

For the first time Rin praised Ars's research.

It's not like he hasn't seen the strange abilities Ars has developed. Only, he considered all those abilities unworthy.

"Let's see if you can withstand this attack."

Suddenly a war appears in Rin's hands.

This was a [Gun Manifestation] and was one of Idaten's abilities that could be used after undergoing training to a certain degree.

"Come, I also want to test the limits of the Unbounded Technique." Ars said.

He believed there was no invincible technique, it only meant that there was not yet a force strong enough to destroy the technique.

He wanted to know the durability of the Unbounded Technique under Rin's attack, which Ars considered the strongest individual he had encountered so far.

*Slash*

Rin swung his sword from top to bottom.

An invisible slash hit Ars.

"Cough."

Ars spewed a mouthful of blood.

"That freedom could cut through a human city. You're just a little bit hurt, you're getting stronger, Ars."

This result makes Rin moved, she looks like a mother who saw her son graduation after a long time in college.

"It seems the Irregularity is still not perfect."

Ars wiped the blood on his mouth, not surprised that his invisible barrier was broken by Rin. After all, he had just comprehended the Infinite Technique and was not used to it, in fact the result was quite good as it was able to withstand a single swing of the sword from Rin.

"Good job, Ars. You have become a mature Idaten, you who now will not lose against the Devil." Rin smiled faintly.

"That means..."

Ars understands the implications behind that sentence.

"En, from today on you have graduated from your training."

"Thank you very much, Rin. Although your training is cruel and merciless, I became strong because you are the indisputable truth. For all your efforts over these 200 years, I am so grateful from the bottom of my heart."

Ars bowed his head like a Japanese custom.

"En, I accept your gratitude."

Rin helps Ars wake up.

"Prontea, since Ars training has been completed, I will increase the intensity of your training."

Looking at Prontea in the distance, Rin said.

"No!!!"

Knowing his training was getting longer, Prontea cried out to the sky sadly.

On the other hand, Ars was amused to see the behavior of Prontea.

"Target next, travel to another world." Mumbled slowly.
