Crossover Anime: From DanMachi to Becoming a Garbage Scavenging Master

Outside, the sound of wooden knives clashing could be heard from time to time.

Yasuri Nanami listened quietly for a while before speaking softly.

"Lord Tianxing, I can rest assured that my good-for-nothing brother has been tempered for a while."

Her voice remained soft and calm, almost indifferent.

"What are your plans after this?"

Zheng Tianxing nodded.

"Next, we need to pay attention to two things."

"The first thing—wait until your younger brother becomes the 'Complete Type-Variant Sword' that Shikisaki Kiki spoke of."

Nanami tilted her head slightly. "Perfect form... variant sword?"

Tianxing nodded again and explained, "You should have heard of this saying. The swordsmith Shikisaki Kiki forged a thousand swords in his lifetime, but only twelve of them can truly be called finished products."

Tianxing paused briefly.

"Each knife represents a philosophy of combat. Some symbolize an unbreakable will. Some symbolize the weight of obsession itself. Some can overwhelm everything simply by sheer numbers. And some represent the pinnacle of skill."

"in other words--"

"Every knife is an answer to what combat is."

Nanami listened quietly without saying a word. Outside, the sound of wooden swords clashing could still be heard intermittently.

"But if each sword represents a fighting philosophy, then a question arises: what is the truly strongest philosophy?"

Tianxing shifted his gaze to the courtyard.

"Hundreds of years ago, after encountering your ancestor, Shikisaki Kiki probably found his own answer. Battle can be a contest between weapons. But battle can also be a matter of human choice."

"And so—the Hollow Blade Style was born."

"That's not a knife, but a 'humanoid knife'—existing to shatter all knives in the world."

The sound of wooden knives clattering outside the courtyard rang out once more.

"Therefore—only by going through this ritual can the Hollow Blade Style be truly completed."

Nanami asked with some curiosity, "So, Lord Tengyo is also planning to bring Nana under his command?"

She paused briefly, her tone remaining gentle.

"After all, that child is a weapon. It would be a shame to just leave him to rust on the island."

Tenxing glanced at Qishi and replied, "That's right. And given those conditions, he'll agree."

Tianxing paused, then continued, "Then there's the second thing. We'll find some time later to go to Mount Yong and bring back a little girl named Dongkong Fenxue safely."

Nanami nodded slightly.

"I see."

As evening fell, Zheng Tianxing stood in front of a tomb.

The grave wasn't large, and the mound of earth wasn't very high. Four characters were crookedly carved on the wooden tombstone—"True Garden Bat." The handwriting was somewhat messy, but very conspicuous. This was the grave left by an earlier invader, on the day he came into this world.

The ring glowed faintly, and the figure of the Black Tower emerged from it. After assessing her surroundings, she asked:

"Is this the place you mentioned where the fragments of rules are?"

Tianxing held up the tiny crystal shard in his hand, gesturing to her. The afterglow of the setting sun fell on the shard's surface, refracting a faint light, like a nearly transparent prism. The ground beneath his feet trembled slightly, as if the world was yearning for him to return this thing. Without hesitation, he put the shard back into the storage space of the Seed of the World.

"In this world, apart from those few swords, almost all the power of the rules is concentrated on the twelve ninjas. Their existence is abnormal in itself for this otherwise ordinary world."

Tianxing held up the fragment in his hand, his gaze slightly somber: "I found this near the body of one of the ninjas. After he died, the power of the rules began to leak out, slowly condensing into fragments, which I then picked up."

"So, those fragments of rules we've picked up in the universe might have come from the same source," Black Tower said thoughtfully. "When an important figure in a broken world falls, the world itself collapses even deeper until it completely perishes. In the end, all that remains are these fragments that can still exist for the time being."

She continued her reasoning: "This line of reasoning makes logical sense. In addition, the will of those shattered worlds has long since dissipated, and these fragments probably can no longer be reused by the original world—a vicious cycle from which there is no escape, which can only lead to destruction."

"But looking at the world's reaction, they are still instinctively trying to reclaim these fragments, so my previous idea of ​​using world fragments to attract new broken worlds should also work. In this way, the efficiency of resource recycling can be improved again."

"Then I'll leave the rest to you to study." Tianxing paused. "Once I've finished dealing with things here, you can start pushing forward with the further development of the relic system."

Black Tower was silent for a moment, then lowered his voice slightly: "Have you made up your mind?"

Tianxing said calmly, "The World Seed of Onpharos is still very weak and can't do much. Didn't we make that decision before entering this shattered world?"

"This damaged world can only provide five jump slots. Including the male and female protagonists, as well as Yasuri Nanami, the Frozen Sky Powder Snow of the Frozen Sky Clan is also a good choice. I'll think about the last one a bit more, but it won't be Maniwa Ninja."

Black Tower nodded as usual, but a hint of melancholy flashed in her eyes. She quickly regained her composure, and her tone returned to rationality: "Since the twelve leaders of the True Garden automatically condense into fragments of rules after death, adjusting them is not complicated. I can just write a separate recycling protocol for this world in the resource recycling system."

She glanced at the fragment again and commented casually, "Although it's just a broken world, the use of its rules is still quite interesting."

Recalling the relic system we just discussed, Tianxing added, "Speaking of the relic system, there's some information that might be helpful for you."

"I've been keeping an eye on the protagonist of this world, Yasuri Shichika. There's something strange about her; she doesn't have much more power of rules than a ninja, and she even has far less than her sister. Logically, the protagonist of a world should have some difference, but I think I've figured out why."

Tianxing further explained, "Before entering this shattered world, I saw its end. Although the world eventually collapsed, it devised an interesting ritual, which I call the 'Folding Knife Ritual,' which can perhaps be seen as the prototype of a rule system."

"By breaking the twelve variant swords that gathered the power of rules, Nanaka unknowingly absorbed their nourishment, becoming what is known as a 'complete variant sword,' and her overall strength was greatly enhanced."

Black Tower seemed to have thought of something, and smiled, saying, "This ritual is quite interesting. Using a folding knife to sublimate the vessel? Accumulating nutrients through the folding knife to gradually move towards the complete form... It's somewhat similar to the Grace System in the DanMachi world, but on a larger scale and limited to the way of the sword."

She paused for a moment, then continued, "Perhaps in the future, a similar ritual could be implemented using the relic system, allowing people to achieve some kind of sublimation. As long as there are enough fragments of rules, this ritual can be used to continuously cultivate sword masters, and in the future, it may even develop into a complete system of rules, allowing us to go even further."

Looking at the Black Tower and contemplating the future, Tianxing began to plan how to recruit the talents of this world into his clan.

Inviting Nana and Toga to join the clan wouldn't be difficult. Given his relationship with Nanami, they shouldn't refuse if their original tragic fate could be reversed.

As for frozen powder snow...

Tianxing frowned slightly. In the original timeline, the girl's entire clan would have been slaughtered by Qishi. Now that wouldn't happen, she had another option.

The child was afraid of loneliness, yet full of curiosity about the outside world. If you simply invited her to explore the outside world, she probably wouldn't refuse.

I'll go there myself then.
