New Power!

Night.

In a hidden basement.

This is the laboratory that Ars secretly built under his house.

Ars lay on the bed with his eyes tightly closed.

On the small table are two canisters. If you look closely, one tube contains a pair of eyeballs, and the other tube contains hair.

"Are you ready?" The clone asked about the condition of his main body.

"Yeah. You can start any time." Ars answered without opening his eyes.

"Okay. Let's begin."

The clone no longer said anything. His face was serious, and his hands formed handprints carefully to avoid the slightest mistake.

Tiger→ Boar→ Burk→ Rabbit→ Dog→ Rat → Bird→ Horse→ Snake→ Clapping.

Putting his palms together, the clone spoke in a solemn voice.

"[Chikara Chūshutsu no Jutsu (Power Extraction Jutsu)]."

Then his palm emitted a black and white light that symbolized Yin and Yang.

The black left hand touches the tube containing a pair of eyeballs, and the white right hand touches the tube containing the hair.

The clone extracted the hidden power that was in the two items. The next moment, his hand felt like it was grasping something.

He put his hand on the main body's eyes, which were still closed.

"Tsk."

Ars clicked his tongue at the excruciating pain he was experiencing.

It was as if his eyes were watered by molten iron. Despite the pain, he didn't make a sound.

This pain was nothing compared to the training period with Rin. Ars had already lost count of the number of times he had been killed while undergoing the most brutal training.

For the sake of obtaining the Sharingan, he had to endure this pain, it was such a small price!

After 800 years of living in this world, Ars abandoned the plan to transplant Sharingan into his eye.

He found a fatal flaw in the method.

What if his head was blown up by a strong enemy? Even though he doesn't die and will regenerate soon, he will lose his Sharingan forever!

After all, the Sharingan wasn't an innate ability in the eyeball itself. When Ars regenerated, he would only regenerate his original body. Meanwhile, Indra's eyeballs are not part of his body, so they will not regenerate.

Although Ars believed that there were very few existences that could match him, that didn't mean there weren't any.

He didn't want to lose his Sharingan forever just because of his pride.

Better to be safe than sorry.

Therefore, Ars created Ninjutsu to extract the power of others.

This is what has happened now.

"It's finished. Let's see, whether it succeeds or fails." The clone reminded him of his main body.

Ars opened his eyes, he still felt tingling in the area around his eyes. Reaching out to take the small mirror on the table, he saw his face.

The color of his eyes didn't change, they were still the same deep red as before, but there were an additional three tomoe in his pupils.

"Huh... My Sharingan can't be deactivated."

Ars was surprised and happy to see that his eyes had become the Sharingan he had always dreamed of hundreds of years ago. However, the Sharingan is always active and cannot be deactivated at will.

"That's not too surprising. Try to remember carefully, Kakashi had to close the Sharingan in his left eye so it wouldn't consume chakra, and Ao had the Byakugan in his right eye doing the same thing. From those two examples, it can be concluded that the Bloodline is needed to control the Dojutsu Sharingan and Byakugan."

"You don't have the Uchiha Bloodline, so it's normal for you to not be able to deactivate the Sharingan."

The clone gave a plausible explanation.

"You have a point. So be it, as long as I wear sunglasses, no one will know I have Sharingan."

Ars didn't think much about this matter. As long as he has the Sharingan, it's fine. Also, he is not like Kakashi who has to close his left eye to conserve chakra.

Idaten was gifted with boundless energy, so he didn't have to worry about consuming the energy that the Sharingan required.

"My task has been completed. I go first."

The clone turned into a puff of white smoke.

"Let's go to the next stage." Ars said cheerfully while concentrating.

The three tomoe in Ars's eyes began to rotate and merge to form a new pattern.

The Mangekyō Sharingan Ars eye pattern consists of three rotating circles, with the eyes visible cut along the circle lines. In the center of the eye pattern, there is a dark ring that surrounds the pupil. The sharp lines and intricate designs give it a unique and frightening look.

"Otsusuki Indra is worthy of being the Ancestor of the Uchiha Clan, his eyes have reached the Eternal Mangekyō Sharingan stage. But... What's with this pattern? Isn't this Sasuke's Eternal Mangekyō Sharingan pattern?"

"The Dojutsu Eternal Mangekyō Sharingan in the left eye is Hinokagutsuchi which produces black flames like Amaterasu, and in the right eye is Kagutsuchi manipulating black flames at will..."

"Haaa... Among the reincarnations of Indra, Sasuke has the most similar characteristics compared to the others."

No matter what, Ars is still happy with the Sharingan.

With his current level of power, the presence or absence of the Sharingan didn't really matter to him.

The biggest reason for wanting the Sharingan is to look cool!

Sharingan is the dream of most otaku!

Ars stared at the mirror until he was satisfied.

"If Megumin and the other Crimson Demons saw my eyes, they would be jealous."

Given the Crimson Demon's Chuunibyou nature, except for Yunyun, Ars was certain that would happen.

"Okay, next."

The Eternal Mangekyō Sharingan turns purple with ripple patterns that spread to the eyeballs.

Rinnegan!

"Eternal Mangekyō Sharingan has successfully evolved to Rinnegan!"

Ars felt that his hundreds of years of waiting had paid off at this moment.

To make the Eternal Mangekyō Sharingan evolve, he wasn't using Hashirama's Cells, but Asura's Cells.

The hair in the tube belonged to Otsutsuki Asura.

Ars secretly dug up Asura's grave, and took some of his hair, and he also put Indra's body in the tomb, so that the two brothers were buried in one place.

"That's good. I can access [Rikudō no Jutsu (Six Paths Technique)]. Even though this is just an ordinary Rinnegan, I like it more than the other Otsusuki Rinnegan."

When the Rinnegan was activated, Ars received information about [Rikudō no Jutsu] consisting of the Deva Path, Asura Path, Animal Path, Human Path, Outer Path, Naraka Path, and Preta Path.

Each Path has its own unique abilities. Ars likes the Outer Path the most, because it can bring the dead back to life!

"Except for some cheesy Isekai anime, the ability to revive the dead is extremely rare. It is even rarer in the cultivation world."

"Compared to the Rinnegan of other Otsusuki Clan members, Hagoromo who has made a contract with the King of Hell, he has a more useful Rinnegan."

"Ha Ha Ha... Look at this, Hagoromo! So what if you seal me? In the end, not only did I escape the seal, I also gained your power!"

Ars laughed out loud, rarely was he in such a good mood.

Despite having problems at the start, the end result was very satisfying. He had the great fortune of coming into this world.
