Chapter 323: Believe in Science

"What's the Illya line?" Tenzan Lixiang frowned in confusion.

"Naturally, it's the worldline where Shilang and Illya love each other deeply," Illya said, placing her right hand on her chest and leaning against Weigong Shilang's left shoulder.

"In this world, Shilang has already given me his heart; there's no room left in him for anyone else."

"After this Holy Grail War ends, we'll return to Germany to marry, living happily ever after in the Einzbern Castle—oh, and it'd be even better if we had two children then."

"Illya…" Weigong Shilang was about to speak when Illya pinched him secretly.

"Didn't Shilang say we'd be together forever? That couldn't have been a lie to manipulate my feelings, right?" Illya hugged the white bear toy, her wine-red eyes locking onto Weigong Shilang's.

【Su Lin: Don't contradict her—she's negotiating with the Chaldea people!】

【Miss Kelaien: Precisely. The war of information has already begun.】

【Xiao Yan: Ssshh—! This woman is terrifyingly intelligent, terrifyingly so!】

【Hakurei Kaguya: You just need to keep smiling. Everything's left to the substitute.】

"It's not impossible—he could eliminate this hidden danger." Red A was no different from me; I too am Zhi Yan Yao Lang, Illya Lang of a Parallel World—so who else could say this better than I?

Illya Lang had been sitting quietly aside all along; in fact, the others' analysis had already led him to certain suspicions.

【Meng Qi: I've already called the police on the substitute.】

It's not that I'm self-centered, but given the current situation, the greatest variable is himself.

"This is Odin's weapon from Norse mythology—yet aside from Shilang's and Gilgamesh's Treasure Vaults, he's also produced the Eternal Spear. According to me, this is the genuine article!"

Weigong Shilang suspected these people were teasing him, but he had no proof.

"What's not good?" Zhi Dunne said: "If he'd chosen your sister back then, he wouldn't have ended up in this state that makes everyone worry!"

"Since he knows of Chaldea's existence and observed you during his travels to other worlds, he must know how formidable your enemies are."

"They probably misunderstood something—if you must state a purpose…"

"If it were merely one of the parallel world clusters branching from the main trunk, that might be acceptable—but the worldline he's in isn't the main trunk."

"We haven't detected any traces of Singularities or Anomalies forming yet," Tenzan Lixiang said to Illya Lang: "We're worried that the gods behind him may have designs on this world. Logically, it's unnatural for us, who descended from a lower dimension, to interfere with an anomalous world at all."

"Be more proactive about giving them benefits," Ye Fan asked Zhi Yan Yao Lang: "So what's your take?"

"Why ask such a question?" Illya Lang said to Lord El-Melloi VII.

But…

"No… what you said isn't true." Zhi Yan Yao Lang glanced at the chat group's messages, then pulled Weigong Shilang up: "We're friends I met during my travels through Parallel Worlds—we never intended to join the Holy Grail War. We merely gave you some help. This Sword of Separation was given to us as a gift."

Only Zhi Dunne among the Chaldea group remained excited; Tenzan Lixiang and Lord El-Melloi VII understood: the other side had no intention of continuing the conversation today.

In these Anomalies, whether humans live in hardship or happiness, everything is decided by humans themselves—not by any single person or god.

"Perhaps it's this Sword of Separation," Illya Lang said: "The goal has been achieved."

"As for the power within me, those are my own secrets."

"Wait a moment, Zhi Dunne—we don't want to meddle in your family affairs. Now is the time to discuss serious matters!" Lord El-Melloi VII, noticing the topic veering off, quickly turned to Illya Lang:

"Let us take over the Einzbern Castle," Weigong Shilang said, holding Illya Lang's arm: "Besides, I'm already living with Su Lin—it's fine."

"Compiled phenomena" are "correct history"; "pruned phenomena" are "possible histories."

"We're off," Weigong Shilang waved goodbye. "Berserker, you go back with Zhi Dunne too—then Seraph won't be able to interfere with me living with Su Lin."

Illya Lang turned and asked: "Please speak."

An Anomaly is precisely a pruned phenomenon formed by accurate development—it's like an "if" route in human history.

I originally intended to glean information indirectly, but the other party had already steered the conversation elsewhere; now, the only option left is to speak plainly.

Lord El-Melloi VII watched the two depart, thought for a moment, then spoke: "Allow me to ask one final question—something trivial, just to satisfy my personal curiosity."

"Is he serious?! He attacked Weigong Shilang!?" Red A's expression twisted.

【Ye Fan: Upstairs, how much are you chipping in?】

"To win the Holy Grail War, you're willing to make a pact with the devil—isn't that your so-called justice?"

Chaldea eliminated the possibilities they created.

"Er… wait, does he want to make you suffer a conscience crisis from back then?" Red A avoided Zhi Dunne's gaze, looking elsewhere; he met Lord El-Melloi's eyes, hoping the other would step in soon.

"Then we'll take our leave," Lord El-Melloi VII rose: "Is this castle outside the outskirts forest?"

The other Chaldea members were stunned—we only wanted to gather intelligence, but not this kind of intelligence.

"Hmm, not quite as expected," Lord El-Melloi VII ignited a small flame on his fingertip and lit a cigarette.

Xi Weng's analyzed data showed that, according to existing records, no mythological accounts match the weapons Zhi Yan Yao Lang used.

"During his battle with Shilang and Gilgamesh, the Eternal Spear appeared on the battlefield."

"Since it's not the main trunk, even minor fluctuations could trigger a world's reaction."

"To be honest, we want to know whether any other forces besides him participated in this Holy Grail War."

Criticize Illya Lang—or criticize myself?

"So Gilgamesh summoned them for this reason…" Illya Lang paused, then roughly understood what Chaldea was now fearing.

"Su Lin, you can't let him commit crimes!"

Red A opened his mouth to speak, but could only stare, utterly stunned.

"Screenshot your phone," Wang Jier replied: "If you weren't panicking to call me, I'd have planned a Dark Mr. Farewell Party with the last few hours."

"Weigong Shilang dislikes the smell of smoke—control yourself, Mr. Waver."

"If they've discovered any hidden danger in this world—like Apostles of the Star God, the Star God itself, strange Heroic Spirits, or Demon Pillars—tell me. I'll help them."

"And he—Illya Lang—who has severed ties with countless Parallel Worlds—is walking a path that cannot be replicated by the planet; every choice he makes cannot spawn new possible worlds."

Illya Lang frowned: "But all I need to do is start this Holy Grail War…"

"Perhaps what he does in the future will have a great impact?" Wang Jier said: "Just a possibility. Right now, this situation isn't even necessarily caused by him—no one can predict the future."

"You and Berserker can testify for Su Lin," Weigong Shilang smiled: "Whether they believe it or not—that's up to them."

"Hercules, does he also know related information?" Lord El-Melloi VII exclaimed in surprise.

Lord El-Melloi VII took out his cigarette again, pulling one out but not lighting it: "The weapon that cut off Shirou's arm—something resembling a whip yet also a sword—what is it? It cannot sever even the soul, preventing the Divine Hero from regenerating, yet it seems to possess no special efficacy against divinity."

"That line from the world of Song Shuhang, from Natsuki Mushiro—this narrative-layered fungal speech probably cost you ten thousand dollars."

"All participants of this Holy Grail War have already arrived in Yuwen Mushi; if there are any other outsiders, they must be from Chaldea."

Overall, it does not harm Dada Liya, but in details, one may be led by the opponent's moves to some extent.

Lu Mingfei: "Need an orthopedic phone number?"

Snap.

What purpose do these beings before him serve? Do they intend to use this as a catalyst to reopen the Mythic Age?

"..."

"If the Shirou Yao Lang of a certain world could truly traverse other universes and grow beyond his own limits and future, he would surely become the most unique worldline—especially if he carries something within him that cannot be replicated by the planet or even the universe. His participation in the Holy Grail War, a pivotal historical node, might even trigger worldline pruning."

"Goodbye, everyone," Dada Liya nodded, preparing to leave the mall to buy ingredients before returning.

"So what?" Dada Liya retorted: "What are you afraid to say outright?"

"Whether you choose to remain in this world to continue observing or return to Chaldea is entirely up to you—if you can, you may witness the final outcome."

Hearing this, Dada Liya took Weigong Shilang's hand and walked toward the supermarket inside the mall; his voice came from behind.

"With these divine powers already present, and your angelic form reappearing in the modern era before the Mythic Age began—do you truly believe this is a good thing for modern society?"

I stated my position plainly: under the condition that my own world avoids danger and disaster, I have no conflict with Chaldea.

But before the cigarette reached his lips, another gust of wind extinguished it.

"Su Lin... he..."

"It's not early today; though I'd like to invite you all to stay overnight, I imagine you're uneasy around me—of course, my home can't accommodate so many people, and explaining it all would be troublesome." Dada Liya glanced around at the familiar faces besides Red A, feeling somewhat troubled:

He hoped the other would reveal more related information; Shirou Gilgamesh believed the gods behind Shirou Yao Lang wished to reappear in the present.

Dada Liya—his way of realizing his ideal, if it takes a radical path, would bring immense and profound impact to this world.

"Mr. Weigong, that reasoning probably doesn't hold," Lord El-Melloi VII paused, then said: "At least tell us their identities."

"That's the so-called Weigong Shilang line..."

He took a deep breath, suppressing shame and the anger of being toyed with as he ruffled Dada Liya's hair, his face still maintaining a smile without words.

And "General Human History" is the correct developmental worldline, the one he can compile phenomena into.

Shirou Yao Lang's voice reached his ears; he glanced at Zhidu Nei beside him and helplessly put away his cigarette.

Wang Jier said: "He told me to tell you—doubt science."

Wang Jier put his phone back in his bag, picked up a cup of Wu Dao tea, and sipped it quickly.

"Where did he get the internet?" Ye Fan's lip twitched. "That's clearly in my world."

Lord El-Melloi VII said: "Now that we've been open with each other, please answer some questions for us—who are the gods behind you? What is their purpose?"

"Imagine General Human History as a branch; beneath it, countless leaves can grow—those leaves are what you call Parallel Worlds," Wang Jier sat cross-legged on a mat, his right hand propping up his head, his left hand scrolling through his phone.

"The Divine Whip."

"Dada Liya, regarding the powers on your body—where do they come from? Can you enlighten us?"

Is it vital intelligence to include the Servant Weigong Shilang in the 'White Beard' category, restricting contact with male Servants, after returning to Chaldea?!

Hercules nodded but said nothing more.

Chaldea found no Special Points or Anomalies formed, only brief warnings appeared; and in this world, no entities like Extraterrestrial Gods have been detected...

Shirou Yao Lang nodded, looked around, and asked: "Where's Miss Kelaien? Why haven't I seen him?"

These worldlines, having deviated too far from correct history, were pruned. Ultimately judged as "History of the Losers."

"This comes from the Baidu Tieba FATE forum—a post you made seventy minutes ago titled 'What Would Happen If Shirou Yao Lang Returned from the Multiverse?'"

Zhidu Nei covered his mouth with both hands, face flushed, and asked: "Is this heaven? So such worldlines actually exist..."

A world where Qin Shi Huang never died; a world where Napoleon conquered Russia; a world where the Mythic Age never began; a world where Columbus never discovered the New Continent, and so on.

This is a negation of the original future, a structure built upon the ruins of original human history.

What is this explosive information...

"The Holy Grail War will begin in a few more days. Aside from Yan Feng Qili and Shirou Gilgamesh, I won't let anyone else go free—no further sacrifices will occur."

In past experiences, you have encountered many benevolent gods, kings, and saints who, harboring the humble ideals of saving mortals and continuing the world, opened Anomalities—not out of selfish desire, but solely to protect humanity in their own way.

Whether it's the power you've displayed or these divine forces of different attributes, though you didn't intend to show them, to the outsiders of Chaldea, they must surely raise many suspicions.
