Crossover Anime: From DanMachi to Becoming a Garbage Scavenging Master

Snow was falling heavily from the sky, and the streets in the distance were nothing but ruins. Not far away, the still-burning flames flickered in the cold wind, and wisps of black smoke rose from the burned-out houses like lingering shadows, making the whole city look desolate and bleak.

The transmigrator Zheng Tianxing walked forward on the broken stone slabs, his boots crushing the ashes and rubble as he slowly made his way through this hellish scene—the ruins before him resembled the traces left behind by a certain "King of the Sky" after his passage.

Just then, a lazy voice rang in Zheng Tianxing's mind.

"Is this the time point you chose?"

Black Tower.

She was Zheng Tianxing's comrade-in-arms in the final battle during his first time travel, but now she has lost her physical body and can only reside in the ring, becoming a veritable "ring granny".

Zheng Tianxing glanced around at the surroundings, confirmed the direction of travel, and then said:

"This is one of the key points that determine the fate of the world, observed from outside the world, and it is not far from Orario."

Orario.

That's the entrance to the dungeon, a city where humans and gods meet, and also the stage where all the stories in that work—Is It Wrong to Try to Pick Up Girls in a Dungeon?

However, there are still 23 years before the story truly begins.

The white-haired, red-eyed youth who ran like a rabbit through the underground city—Bell Crane—hadn't even been born yet.

Black Tower chuckled softly.

"So, you're here for that child."

"Alphia, a monster of talent," she added slowly. "Theoretically speaking, besides Bell, she is the most gifted person of this era."

Zheng Tianxing stepped over a broken beam and explained:

"If she were not bound by fate, and given enough time to hone her skills, she should be able to slay the ultimate trial of this world—the Black Dragon—on her own."

"That certainly has great potential." Heita paused, a hint of regret in his voice.

"It's a pity that the power wasn't preserved, otherwise I could have studied it and perhaps improved the framework of the simulated universe."

"That thing never belonged to us, and we can't keep it for long."

"Being able to exchange it for what it is now is already considered a profit."

The black tower counted slowly.

"You mean—divine status, qualification to descend to the mortal realm, and... legal residency as a person from another world?"

"That's right."

Zheng Tianxing looked up at the sky, snowflakes falling continuously onto his face, the icy sensation bringing him back to his senses from the bewilderment of his previous failure.

"Given enough time to stay, we will eventually be able to analyze the two most fundamental rule systems in this world."

Black Tower immediately took over.

"The Grace System cultivates the strong, while the Dungeon System constructs the rules for trials. The two systems then complement each other, supporting a complete advancement system."

She suddenly chuckled softly.

"So, in this new world, what should I call you?"

Zheng Tianxing spoke calmly.

"Prometheus, call me Prometheus, the God."

Black Tower chuckled.

"You adapted quite quickly."

Just then, Zheng Tianxing stopped. In the shadows of a corner not far away, two thin figures were huddled together—their clothes were tattered, and their bodies were shivering in the cold wind, like two small animals trapped by the harsh winter with nowhere to escape.

Zheng Tianxing didn't immediately go over; he simply stood there, quietly watching them. Deep within his mind, some images that shouldn't belong to this point in time quietly surfaced. They were the original trajectory of the girl Alphia's destiny, a timeline before his intervention.

Soon after, Hera's Familia will pass by these ruins and take the two sisters away and shelter them.

Alphia will grow rapidly under the Grace System, and her talent will shine like a shooting star in the night sky, even among the powerful Hera Familia.

Seven years later, on the battlefield against Leviathan, the "King of the Sea," she will pour all her power into her ultimate attack, sacrificing her own health for the victory of her clan. Having survived with her wounds intact, she will continue to advance.

Then, in the eighth year, the Families of Zeus and Hera joined forces to attack the Black Dragon's expedition. Upon encountering the Black Dragon, the expeditionary force was almost instantly annihilated. Darkness descended too quickly, so quickly that no one had time to react.

finally--

She was the only one left alive, licking her wounds that would never heal.

Her body had long since reached its end, but she did not choose to die alone.

She chose to stay, as a trial, as a necessary evil.

Use your own defeat to ignite new heroes, allowing them to grow stronger through despair and battle.

And she herself—

It then sank into the depths of history, becoming an insignificant footnote.

So tragic, so desolate.

As for Metalia, there are almost no observable traces.

However, judging from Alphia's attitude towards Belkrani, the future protagonist of this world, we can infer that she must have secretly given birth to a child with white hair and red eyes in some unnoticed corner.

Zheng Tianxing let out a soft breath, but that was just the original story. The future, however, would be changed because of him.

-----------------

Amidst the wind and snow, a quiet commotion could be heard.

Alphia suddenly raised her head, her gaze instantly becoming wary.

A young man with black hair and red eyes emerged from the ruins. He looked no more than eighteen years old, yet possessed an imposing presence. As he drew closer, her body instinctively warned her that this young man was no ordinary person.

The young man stopped in front of them, as if he already knew everything, and announced:

"I will kidnap you, and you will become my maids."

"Live in a spacious house, wear beautiful clothes, and eat hot white bread every day."

"Then work for me, fight for me."

"In exchange, I will take you away from here."

Their gaze fell on Metalia.

"I will also cure your illnesses."

The air suddenly fell silent, and the two sisters were somewhat stunned.

Melia buried her head in her sister's arms and whispered, her voice soft but unusually firm:

"It's fine for my sister to decide."

Alphia remained silent for a moment.

From a very young age, she understood—

Fate gave her all the light, but left the shadows to her sister.

She was destined to become her sister's shield, protecting her from all the malice of this world.

but……

The sudden disaster took everything from them. And could the younger sister's naturally weak constitution really be cured? Their choices were actually quite limited.

She looked up at the young man again. His expression remained calm, as if what he had just said was nothing more than a trivial matter. It was precisely this matter-of-fact certainty that made something inside her quietly relax.

Metalia seemed to sense her sister's wavering. She struggled to sit up straight and tried to speak loudly:

"Please...please take my sister away. She's very capable; she can serve you well. And I'm just—"

Before he could finish speaking, the young man had already walked up to him.

He bent down and grasped both sisters' wrists at the same time. The next instant, a warm light shone from his palms, slowly spreading along their wrists, like melting snow water quietly seeping into their skin, yet carrying a subtle warmth that flowed deep into their bodies.

Metalia trembled slightly. The warmth seeped into her body, dispelling the chill that had settled in her limbs, making her feel surprisingly light. Even the biting wind on her face no longer felt piercing.

Alphia felt much the same way. A warmth of inexplicable origin quietly lifted the weight that had accumulated on her shoulders.

The warm light slowly dissipated, and the young man helped the two sisters up.

After they steadied themselves, they turned around almost simultaneously and looked at each other.

The shock in each other's eyes was exactly the same.

The young man said calmly.

"I've said it before, the two of you—you can't be missing."

He stood up, the wind and snow swirling behind him. His voice wasn't loud, but it carried an undeniable authority.

"The commands of the gods are non-negotiable."

After saying that, he turned and walked forward.

"Oh, right."

The young man turned and glanced at them.

"Remember my name, Prometheus. Follow me!"

The sisters looked at each other again, as if they had made a decision, and then stood up at the same time.

Their lives began to turn anew from this moment on.
