My Alter Ego's Path to Greatness

"I heard you requested a meeting."

The owner of the hospital director's office in the Azelion Imperial Hospital opened his mouth with his usual cold expression. Hesperon, who was sitting across from him, nodded solemnly.

"Yes. It's about the prosthetic eye in my eye…"

He spoke and raised a hand to stroke the eyepatch covering his right eye.

After losing his eyeball on the day of the Riley attack, a prosthetic eye that had been installed arbitrarily at the hospital was placed in his right eye socket.

It was an action taken to prevent the left-right balance of the face from collapsing if the empty orbit was left as it was. Since the prosthetic eye had been prepared at the imperial hospital, it was a high-end product that could not be easily found.

It could be said to be a magic tool that used magic stones as its core and had all sorts of beneficial effects related to health attached to it.

"I wanted to replace it."

Therefore, the hospital director frowned subtly when he saw the pearly white orb that Hesperon presented.

A smooth orb with a pearly white color, the size of a normal adult's eyeball.

It did look extraordinary enough that, he, who had vast knowledge in various fields, could not figure out what the material was, but he didn't feel any special power from it.

'It's not carved with magic circles, nor is it a cursed item. And, there is no magic stone in it in the first place.'

To put it bluntly, it was nothing more or less than an ornament.

The hospital director, who was gazing at it quietly, turned his gaze back to the patient.

Anyway, he had a duty to do his best as a doctor.

"The cultivation of your artificial eyeball is almost finished. Of course, it won't restore your vision in your case, Hesperon-nim, but you will at least be able to look perfectly the same as before on the outside."

The movement of the pupils, as well as things like focus adjustments.

The director continued calmly, saying that he wouldn't need to wear an eyepatch anymore if that happened.

"Of course, it's not difficult to replace your prosthetic eye, but you're going to have an artificial eyeball implanted soon, so do you really need to do it?"

Hesperon nodded firmly to his words.

Unlike before, he needed to do it now.

"Yes, please."

"I understand."

When it seemed like his intention was firm, the director did not say anything further and agreed.

As if he was willing to follow the patient's wishes as much as possible, since such a minor problem would not have a big influence on the treatment results.

'It'll be a different response if he refuses the implantation of the artificial eyeball later, though.'

He was sorry to have him waste his effort, but it was inevitable since it was not something that would restore his vision, anyway.

Since it was his eye, shouldn't he choose the most efficient and helpful one?

Right after undergoing a simple procedure and replacing the prosthetic eye.

Hesperon, who had returned to his personal room inside the hospital as if nothing had happened, stared quietly into the mirror.

'…As I expected. Even the grand mage can't recognize it in this state.'

The pearly white sphere that was in his right eye socket.

The identity of it, which even the director had failed to discern, was the prosthetic eye that he had taken from Yullyeongja, known as "Callicas's Mechanical Eye".

It just looked like a bead of a unique material right now, since all of its mysteries and functions had stopped when it had crossed the dimension, unless someone was to take it apart and look inside.

'I didn't need to go all the way to Earth, pretending that I was trying to keep it a secret.'

Since, what was more important than the procedure itself, was how to operate it after that.

In its current state, it was just a half-baked item that could only be used on Earth.

'If that were the case, it would be better to just break it down and use it as nutrients for Howard. The best thing would be to create an environment that would allow me to collect field usage data as well as do regular maintenance and analysis, though.'

And the most optimal candidate for that was Hesperon.

He was in a situation where he was missing an eye, and…

"Phew, then… shall we begin?"

He had a secret plan that would allow him to bypass even such dimensional limitations.

Hesperon, who took a deep breath, closed his eyes and focused his mind on his right prosthetic eye.

"..."

A magic tool from one world could not be used in another.

That was an absolute law that an individual could not do anything about.

However, wasn't there another major premise that came before that?

That the existence called an Awakened one was an exception even from those dimensional laws.

'Then.'

What if the magic tool and the Awakened one could be completely bound together as one?

What if he could make it recognize it as a part of his own body, transcending the relationship between user and tool?

'It's impossible for others, but…'

He had an ability that would make that possible.

Soon, his ability, "Chain of the Oath", was activated and began to communicate with the prosthetic eye that had stopped operating.

———!

A sharp pain that started from his eye and traveled all the way to his brain.

He felt an extreme resistance that surpassed everything he had experienced so far.

He had experienced this before when sealing his right arm. But just as he had felt that time, as the level of the target increased, the difficulty also rose. The initial stage alone was very difficult.

Moreover, wasn't that prosthetic eye completely deactivated right now?

Naturally, it would be even more difficult to communicate with it.

'But… I already expected this much.'

That was why he needed Howard's "Technological Revolution".

An ability that allowed him to intervene in the system that made up an item from another dimension and modify part of it.

'If the problem is that the laws of each dimension are different, then I can just tweak that part so that it becomes compatible!'

Reorganizing the internal structure to allow some of the functions that would not have been able to be used to be used.

Of course, it was impossible to completely reactivate it since he had not had this ability for long, but…

He could still do small things, for example—.

He could at least give a little breath of life to the completely silent functions.

Buzz—

A small vibration was felt on his eye socket as the conditions that he had set in advance were met.

A subtle operating sound that was not heard outside, but was felt by him through his skull.

'It's done.'

At that fleeting moment.

The "Chain of the Oath", which had rapidly infiltrated the inside, did not miss the opportunity.

'Now, come here.'

Encounter, Negotiation, Coordination, Compromise, Coercion, Control…

The process of taking complete control of the target and binding each other as one was also carried out at lightning speed after that.

And, at the same time that series of processes ended, countless green symbols appeared in his right field of vision, which had been completely dark. Then, they began to quickly scroll up.

And a sentence that was located in the center.

"…It was a success."

Hesperon, who had been staring blankly at the sentence, turned back to the mirror again.

The smooth surface of the prosthetic eye, which had been a simple pearly white, was now showing a fast stream of various symbols.

Like a computer that had just started booting up.

A few seconds later.
