Thanks for the invitation. I'm in Type-Moon, inheriting the legacy of Zi-O.

"Wow..." Nianzhuo pinched his cheek dumbly. "This is too... lucky."

Then, Nianzhuo felt someone tug at his clothes. He turned around and saw Kintaros being very cautious.

"Hey hey..." As Nianzhuo leaned closer, Kintaros whispered in Nianzhuo's ear, "What are spiritual veins..."

“Hmm, I’m also curious about that.” Ryotaro, who was sitting at the table, nodded and leaned closer to Nencho. “And what exactly is luck…?”

"Ah, this..." Nian Zhuo looked at the two inquisitive eyes in front of him and scratched his cheek. "In short, just think of it as if Urtaros suddenly became the king of the harem, and his harem was full of cute girls. Spirit veins are pretty much the same thing to us." Finally, having chosen a metaphor that was roughly correct, Nian Zhuo waved his hand and pushed Urtaros away.

"Oh, I see." Ryotaro adjusted his glasses and smiled knowingly. "That's really lucky..."

"Huh?" Kintaros, whose mind was now all muscles, looked completely clueless, glancing at Ryotaro and then at Nencho. "What are you guys talking about?"

Inside the Time Train, Momotaros and Ryutaros laughed so hard they fell to the ground, while Urataros crossed his arms and snorted defiantly.

"There are still plenty of girls willing to take my bait..." he weakly argued.

“Yes, senior, Mr. Nianzhuo.” Looking at Ritsuka and the smiling Nianzhuo, Mash, who had used her shield to confirm the location, also smiled. “Summoning circles can be set up in this room. Could it be that Mr. Jekyll knew about the existence of the spiritual veins, which is why he built the workshop here?”

“No, I’m not a proper magician.” Jekyll shook his head. “So this isn’t a magic workshop either; this is just my room.” He then pointed to Mash’s shield, his tone tinged with curiosity.

"However, you are free to use this place. But I'd like to ask you first, what do you want to do?"

"Establish Chaldea's summoning circle on the spiritual vein." This time, it was Marie who answered through the communication device. "It can enhance the combat power of Nen no Omo, Ritsuka, and Mash. Although the Servants summoned through the circle may not be able to act continuously, they can provide tremendous assistance in battle!" Marie then added quietly, "Although no other Servants have appeared yet..."

Mary coughed twice and urged Ritsuka and Mashu to hurry up.

"In conclusion, let's start setting up the summoning circle."

“Understood.” Mashu nodded and placed the shield on the ground. “Then, begin establishing the terminal point—”

One by one, pure white orbs of light emerged from Mash's shield, gradually forming a circle.

"Okay~" A familiar voice came from the communication device, making Nian Zhuo's hair stand on end. "So, while the summoning circle is being set up, let me, Da Vinci, keep everyone company and help pass the time!"

"Ah, this—" Nian Zhuo really didn't dare to face this unscrupulous merchant, and his tone was somewhat unsure.

"Ahem, Nian Zhuo." Unexpectedly, Da Vinci took the initiative to talk to Nian Zhuo, which startled Nian Zhuo so much that he sat up straight instantly. "I remember I talked to you about class compatibility before, so let's continue on that topic this time."

"Okay, okay!" Nianzhuo nodded and sat up straight.

“Each heroic spirit has its own legend and story. Based on their origins, they can be divided into several types.”

These are the three attributes: Heaven, Earth, and Human. Most Servants belong to one of these three categories.

"Heaven" refers to a divine spirit descended to earth, or the son of God, a manifestation of legend.

The land is also home to local legends, including heroes, fairies, and monsters.

People are heroes and great figures who actually existed, like myself! And great artists who actually existed!

Listening to Leonardo da Vinci's self-praise, Nian Zhuo curled her lips but did not interrupt her.

Heaven overcomes Earth, yet is overcome by man.

Earth overcomes man, but heaven overcomes him.

Man can control the heavens, but is controlled by the earth.

...This is precisely because humans believe in gods, but from another perspective, if people lose their trust, then gods cease to exist.

Heroes or fairies rooted in the land have nothing to do with faith, yet on the other hand, they are also unable to defeat the gods who created them.

...In addition, there are a small number of special heroic spirits that do not belong to any of these three attributes.

For some reason, Nianzhuo felt Da Vinci's gaze shift to him.

"An exception among exceptions—that is the Star Spirits."

It belongs neither to heaven, nor to earth, nor to man.

Yet, it exists beneath the sky and above the earth, a being born of humankind.

The Star Servants have nothing to do with the mutual generation and restraint of Heaven, Earth, and Man; after all, they are the exceptions.

That being said, this is ultimately just a classification.

Da Vinci waved his hand, indicating that Ritsuka and the others didn't really need to care.

"Ahem..." After seeing that Ritsuka's summoning circle was completed, Da Vinci coughed a few times and then bid them farewell. "Let's call it a day. The summoning circle is complete. Good luck to you all in this era!"

Wishing for Klee! Wishing for Klee!

"Phew—" With arms outstretched, Romani looked like he was finally off work. "Finally done!"

“Yes, thank you.” Mary, in the control room, nodded. “Thank you, Romani, and Leonardo da Vinci. Thank you for your help this time.”

“Mom, it’s nothing.” Romani waved his hand and let out a long sigh. “After all, this is the fourth time. We should get used to it.” Leonardo da Vinci nodded in agreement.

"Well, since it was my idea to help you, Mary, you don't need to thank me for such a small thing. But—" Da Vinci drawled, "—about the expansion of my magic workshop~"

“…Is that so?” Mary nodded knowingly, then placed her finger on the button to cut off the communication. “Dream on.”

Before Da Vinci could react, Mary pressed the button to cut off the communication, a smug smile on her lips.

On the other side, Jekyll, who had been watching Mash establish the summoning circle, suddenly spoke up.

“…Um…that…” Her cheeks flushed slightly, and she looked a little embarrassed. “Who was that just now? She was very beautiful…but, it wasn’t a real person, was it?” Recalling the blue image she had just seen, Jekyll didn’t think that was the other person’s true appearance.

"Fu! Fu!" After the summoning circle was established, a furry animal darted out of Mashu's shield and ran onto Nianzhuo's shoulder.

"...??" Jekyll stared in surprise at the tiny monster that had emerged from the shield. "And this is...?"

Fou pricked up her long ears, tilted her head, and sized up Jekyll in front of her. Her gaze paused noticeably when it moved to Mordred.

"...Hmm. This guy looks familiar?" Mordred stroked her chin, her emerald green eyes fixed on Fou on Nianzhuo's shoulder, feeling like she'd seen her somewhere before. "Is it a fantasy species?"

"Fou, Fuu..." Upon seeing Mordred, Fuu's voice grew softer and softer, and she even shrank back behind Nianzhuo.

"Eh—" Mordred blushed slightly, and the usually carefree girl showed a rare look of affection when facing Fou.

“As expected…” Nian Zhuo shook his head, looking as if he had already guessed it. “Based on my memories of the Holy Grail War… Mordred has no resistance to these fluffy little animals—” Nian Zhuo hugged Fou in his arms and skillfully stroked its fur.

"It feels so good—" Nianzhuo couldn't help but think, and suddenly he understood why so many people liked petting cats.

"Fou?" Mashu was somewhat surprised. "Fou is usually very friendly to strangers, so why is she so resistant to Miss Mordred...?" But in the end, she kept it to herself and didn't say it directly.

"Hey, it's an animal I've never seen before." Jekyll pushed up his glasses, looking at Fou's body with curiosity in his eyes. "Could it be a rare animal from Africa?" Then, seeing that everyone's eyes were on him, he coughed twice to indicate that they shouldn't mind.

“But speaking of which, Saber, Mash, Ritsuka, and Nencho—and Mr. Ryotaro over there.” Jekyll picked up the teacup on the table. “Let’s get straight to the point—I have some things I’d like to ask you.”

"Oh?" Nian Zhuo became interested instead. He gently placed Fufu on the ground and stood up. "Let's just say it directly. After all, we are allies now, and you have provided us with such a base."

"Yes, that's right." Ritsuka stretched comfortably on the sofa. "After all, Mr. Jekyll really helped us a lot, and friends should always help each other, right?"

“…Yes, thank you.” Jekyll adjusted his glasses with a slightly surprised expression, his smile equally gentle. “If possible, I hope you can investigate the magical mist that surrounds the entire city of London again. Of course, Saber will accompany you.” He glanced at Mordred beside him.

"...Huh?" Mordred, who was comfortably drinking cider on the sofa, was instantly stunned. "I just came out of the magic mist, and you want me to go back?"

“After all, your strength is also necessary.” Jekyll shook his head helplessly. “Don’t worry, I will prepare new chilled cider for you when you come back this time.”

"Really?" Mordred jumped up instantly, tossing the bottle aside. "No backing out, okay? Let's go together then!"

"Are you a child...?" Nian Zhuo looked at Mordred, who was clamoring to leave again, with a face full of black lines. "You were won over by chilled cider, huh...?"

After muttering to himself, he looked at Ritsuka and Mashu behind him... as well as Ryotaro and the others.

"Okay, go ahead~" Ritsuka nodded in agreement, though she was a little reluctant to leave the sofa.

"Yes, let's go, Mr. Nianzhuo." This came from Mashu, who was now ready again.

"Well, I don't have any problems." Setting the newspaper aside, Ryotaro adjusted his glasses. "However, we don't know enough about this world yet, so I also agree to set off."

"Hmph, only through tempering can my strength be revealed!" Kintaros clenched his fists, ready to strike.

“See?” Turning around, Nian Zhuo shrugged at Jekyll. “That’s our answer.”

“Thank you very much. Well, there’s one more thing—” Jekyll spoke again, looking at Mordred, “I hope—you can go somewhere with Saber.”

"Just these two things?" Nian Zhuo asked, raising his hand after receiving Jekyll's affirmative reply. "Then, let Mordred tell us the details of the mission on the way. Let's set off now!"

“Then, I leave everything to you.” Jekyll bowed slightly and solemnly. “Please be careful.”

"Don't worry!" Mordred patted Jekyll on the shoulder cheerfully, noticing his face turn pale instantly. "We'll be back soon. But make sure you get me some cider before then!"

“Yes, don’t worry.” Jekyll nodded and opened the heavy wooden door.

"Hmm, everyone seems quite motivated, especially Mordred." Nian Zhuo nodded silently, then stepped out the door. "It seems we might have a good harvest this time."

A few minutes later, Nianzhuo realized just how wrong he had been.

"...Ugh, so tired." Mordred slumped weakly, carrying her sword, looking utterly exasperated. "I just got back, and now I'm back in the demonic mist. This is so exhausting!"

“I’m so sorry…” Mash lowered her head slightly, while still gripping her shield warily as she looked at Mordred, who was leading the way. “We need your help to show us the way, as we’re not very familiar with the streets of London.”

"Ah, it's nothing, don't worry about it." Mordred tossed her golden ponytail and led Nianzhuo and his group through the smoke-filled road. "If you hadn't come, this would have been my job anyway." Scratching her golden hair, Mordred turned her head to the side.

"In fact, I should be thanking you all." Mordred chuckled and turned around. "Sorry for dragging you into this ridiculous mess."

“No, Mordred, that’s not true…” Mashu shook her head. She always used honorifics when addressing others, but for some reason, she felt that she didn’t need to use them when addressing Mordred.

“Hmm… based on what you just said—” Mary’s voice came through the communication device, “our main mission this time is to protect one of Jekyll’s assistants, the Swiss scholar Frankenstein? We’ve reportedly lost contact with him since this morning. Do you usually communicate via radio?”

“Ah, that—” Mordred scratched his head, looking somewhat troubled, when asked about information related to the mission. “Jekyll is the one making the communications. He said it’s his intelligence network, so I’m not very clear on it… He has assistants all over the city, and they often contact him via radio. At least until yesterday, old man Victor was safe and sound.”

“I see.” Mary flipped through the report in her hand, raising an eyebrow. “But Victor Frankenstein—I thought he would be a character from a novel, but it turns out he’s his descendant.”

“Mr. Jekyll said that the magician who was the prototype for the character in that novel was this scholar’s ​​grandfather.” Mashu lowered her eyes, her tone also somewhat surprised. “It is indeed quite unexpected. According to Mary Shelley’s description in the novel… Dr. Frankenstein was a scientist, yet the prototype for the character was a real magician. It makes one think of the Far Eastern proverb: reality is stranger than fiction.”

"Huh, is it that strange?" Ritsuka, who wasn't very familiar with the world of magic, was puzzled. "Are magicians and scientists really that different?"

“Yes.” Mash nodded without hesitation. “Because magic and science are supposed to be completely opposite technologies. Chaldea… well, they are an extreme exception. Thinking about it this way, from the perspective of the world and history—”

“Ah, um, Mashu is right, but there are always exceptions.” Mary looked at the modern, technologically advanced machines around her and rubbed her temples. “In some eras, science and magic were almost synonymous. Not just in the age of gods or ancient times, for example, you could say that alchemy is the origin of chemistry. Many of the famous scientists, chemists, and scholars we know were also magicians.” Suddenly, a thought flashed through Mary’s mind; she remembered that incessantly chattering, shrewd merchant from earlier.

"Oh, by the way, think about it, after all, Leonardo da Vinci was one, wasn't he?"

"Ah—" Mash's eyes widened as she realized that there was indeed a Heroic Spirit beside her who was a famous artist and scientist but appeared in the world as a magician.

"Hmm?" Sure enough, the communication spell that Leonardo da Vinci had set up flashed, "Are you calling me?"

"Well, it was just your turn to talk~" Mary crossed her arms, her orange eyes smiling slightly. "We were just discussing the boundary between science and magic, and I just thought of you as an example, so I brought it up~"

"Ah, so it's a topic of science and magic." Da Vinci, on the other end, nodded and picked up his coffee. "But using me as an example is useless, because... I'm omnipotent. No one can compare to me, what a pity... Ah, well then, see you later." He then quickly ended the communication spell.

"Ah, the communication is down." Mashu listened blankly to the static on the other end.
