My Alter Ego’s Path to Greatness

Auterica, where most of his avatars were active.

Ganghwange, the recently discovered dimension.

And Earth, his main base of operations, where his main body resided.

Living in multiple bodies across different worlds had given him countless insights.

But among all those experiences, one stood out.

…Time.

‘It makes sense. I've been focusing on Earth lately…’

A tenfold difference in time flow.

It was a significant gap.

So, while it felt like only a short time had passed on Earth, considering the scale of the events he had experienced, it was a different story in other worlds.

Auterica, Roselia Temple, located in the heart of the holy land.

“Welcome back, Saint. You’ve returned earlier than expected.”

“Ah, Lady Lyrin. You’re working hard, as always.”

Heinrich, having just entered the temple, turned to face the blue-haired woman who had greeted him.

She was a member of the Radiant Guardian Paladin Order, an elite unit responsible for protecting the Roselia Temple, the same order he had once belonged to.

She approached him, her steps precise and measured, and bowed respectfully.

“The Saintess has been asking for you. It seems she has something to discuss.”

“I see. Thank you for letting me know, Lady Lyrin.”

“It’s my duty, Saint. Then, I’ll be going.”

“Yes, please.”

She bowed again and turned to leave.

She had been his mentor when he first joined the temple, and they had maintained a relatively close relationship since then.

He didn’t have many close acquaintances, having risen through the ranks so quickly.

‘She was the one who told me about the Immortal King’s fragment hidden within the temple.’

Of course, it had been part of her duties as a guard, but it had been a valuable piece of information, playing a significant role in his subsequent actions.

Heinrich chuckled softly, then continued his walk through the temple.

‘Liesta was looking for me? Probably about Earth again. Well, I’ve been going back and forth so often, she must have guessed.’

He hadn't been going to Earth without the Church's knowledge.

Even with the recent lull in giant attacks, he couldn't just disappear without a word. He was the Saint, the symbol of the Church's military might.

‘So, I told them the truth.’

That he would be briefly visiting another world from time to time.

‘Of course, I framed it as a divine mission.’

It wasn't a lie, technically. And they were all devout believers, so even interdimensional travel was seen as a minor miracle, a blessing from God.

And the Saintess, who had become curious about other worlds after Hesperon and Isea revealed their Earthling origins, was already conducting her own research.

‘I should talk to Isea soon.’

She was about to return to Earth.

Probably after the final battle against the Immortal King.

He should warn her beforehand. She might feel betrayed if she learned the truth after returning.

‘And that would jeopardize our cooperation on Earth.’

She had poured all her Karma into returning, driven by her longing for her family.

He could be a valuable contact for her, a link between dimensions.

‘She’s close to transcendence. It’s always good to have more powerful allies.’

She could relay messages to his family in Korea, and maintain indirect contact with Riley after returning. It would be beneficial for her as well.

But there was one thing that bothered him.

‘I have to keep Hans’s identity a secret.’

A Demon King in one world, a dark hero in another?

To prevent that awkward encounter, he needed to restrict Hans’s activities to overseas locations.

‘Korea is stable now. There’s no need for Hans to be there. As long as they don’t meet face-to-face…’

He could just dismiss any photos or videos as coincidences, a case of mistaken identity.

Their personalities were completely different, the black robe wasn't unique, and the Hahoe mask was a traditional Korean symbol.

‘And ever since Isea found out I’m Korean, I’ve been wearing a broken mask in Auterica.’

But he wasn’t confident he could maintain the charade if they met in person.

It wouldn't be a disaster if his secret was revealed, the main scenario was practically over… but it was better to avoid any potential complications.

‘I’ll be going to Earth again in a few days, so I should finish my work here… Right, I should visit Liesta.’

The cooldown on 「Interdimensional Transfer Formation Summon」 was twelve hours in Earth time.

He could easily manage both worlds, since he only spent a few hours on Earth each time.

Of course, using the transfer formation so frequently might limit his other avatars’ mobility…

‘But there aren’t any urgent matters right now.’

The only major event left in Auterica was the final act of his Home Theater.

They were in the calm before the storm.

A private workshop in Tarak.

“Oh! Finally!”

After the incident with the prototype, Howard had moved out of Zaonic’s workshop and into his own, newly built facility.

Zaonic had told him he could stay, but with Hubert’s Trading Company backing him, he didn’t need to impose.

And they were practically neighbors, so it wouldn’t affect their daily interactions.

“It’s finally complete!”

But having his own secret base was… exhilarating.

He had been working tirelessly since moving in, driven by a newfound inspiration, and after several weeks of dedicated effort, he had finally achieved a significant breakthrough.

“The Multipurpose Combat Power Suit Mk.2’s left arm!”

It was just a single arm, but…

He held it aloft, admiring his creation with gleaming eyes.

A mechanical arm, radiating power.

It wasn’t just an ordinary prosthetic.

The materials, the technology, even the energy source within… everything was extraordinary.

‘Technology is important, but capital is a craftsman’s greatest virtue!’

A top-grade magic stone.

Just below a Dragon Heart, an incredibly rare and valuable item.

Even the imperial palace only used top-grade magic stones for their barriers, reserving Dragon Hearts for emergencies.

‘I used one last time to rescue Diana from the Revolutionary…’

He had used such a precious item as a disposable power source for the suit. That’s how Hubert, with his limited abilities, had managed to escape the giant.

And now, that same level of power was contained within this single arm.

‘It wouldn’t have been possible without the Ten Thousand Year Cold Iron from Ganghwange and the Adamantium from the demon world.’

Both materials were renowned for their durability and energy resistance.

Creating an alloy from them wasn’t easy, but Howard, using 「Song of Fire and Metal」, 「Metallurgy」, and 「Technological Revolution」, had finally succeeded.

The resulting alloy, a perfect blend of their properties, formed the intricate circuits within the arm, allowing it to withstand the immense energy of the magic stone core.

A power suit, combining fantasy dwarven craftsmanship with materials from the Murim and demon worlds, incorporating futuristic technology!

“Mwahahaha! It’s like having a miniature spaceship attached to my arm! I can’t wait to see what it can do when all the parts are assembled!”

He danced around excitedly, holding the mechanical arm aloft, then suddenly stopped.

He stared at it intently, stroking his beard thoughtfully.

“Hmm, it needs a proper name.”

He couldn't keep calling it the “Multipurpose Combat Power Suit”.

It deserved a more… impactful title.

“Hmm, how about… ‘Iron Guy’? No, that’s too derivative. Then ‘Captain Auterica’… No, that’s not right either.”

He struggled with the naming process for a while, then sighed, giving up.

“‘Titan’! It sounds powerful, like a small giant. And I’m a dwarf, so naming it after a god isn’t a bad idea…”

As he muttered to himself, having finally settled on a name,

Whoosh—

A tongue of flame suddenly erupted from the nearby forge, swirling around him.

And as the flames subsided, several messages appeared before him.

《Titan gazes upon you.》

《The individual meets the conditions and grows. The special skill “Song of Fire and Metal” evolves into “Harmonizer of Fire and Metal”.》

It wasn’t his first time experiencing this.

“This is… the forge’s blessing?”

It was a sign of a god’s favor, bestowed upon a craftsman who created something significant or reached a new level of mastery.

‘So… he likes it.’

It seemed Titan, the god of the forge, approved of his creation.

This new invention, named after him, which had never existed before in this world.

Whoosh—

The gentle sound of waves crashing against the shore.

A beautiful beach, the salty air adding to its charm.

“Ughhh!”

A muffled groan echoed from within a hidden cave, carved into the cliff face overlooking the beach.

“If I… do this…”

A childish voice, its words slurred and indistinct.

A cute little boy, about six or seven years old, with golden hair, sparkling golden eyes, smooth skin, and chubby cheeks.

Horus, the last Gold Dragon hatchling in Auterica.

He stood on a chair in a magical laboratory, filled with strange equipment, struggling with something on the table before him…

“Got it!”

…And then, with a triumphant shout, he raised his hands in the air.

And then—

“Hmm, what’s that?”

“Eek?!”

He flinched at the sudden voice, then turned around with a smile.

Shri Hartgen, the Gold Dragon Elder, stood behind him, his eyes half-closed.

“Hee hee…”

“…That’s… unusual. Where did you get that?”

The old dragon’s gaze shifted to the object on the table.

His body might be withered and frail, his life force fading, but he could still sense the unusual energy emanating from it.

“This is… dwarven craftsmanship. And quite… impressive. Was it designed for enchantment?”

His tired eyes widened in surprise as he examined the object.

“Hmm, this isn’t just basic enchantment knowledge. This requires the insight of an Archmage.”

It was a surprising discovery.

Dwarves, those stubborn craftsmen, took pride in creating items that surpassed even enchanted magic tools through their crafting alone.

They rarely collaborated with enchanters, preferring to complete their creations independently.

And the underlying knowledge required for this design… was Archmage level?

‘Did this child enchant it? …This is… remarkable. The harmony between the dwarven craftsmanship and the enchantment is perfect. It’s as if a single person created it.’

He glanced at Horus, a newfound respect in his eyes, then returned his attention to the object.

A sleek, smooth design, crafted from a dark, unfamiliar metal, its curves elegant and flowing.

A piece of armor, its style unlike anything he had seen in his long life. A left arm.
