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

"Ah, you can rest assured about that." Mary said with an air of "I knew you'd ask that," crossing her arms and looking smugly at the screen where Nian Zhuo and the others' movement path had been marked. "I've drawn a map of where you've been, so you shouldn't be going around in circles. Hmm." She clapped her hands with an air of seriousness, but looked at Ritsuka on the screen with a worried expression.

"Instead of that, given Ritsuka's physical condition, I still suggest that you should take a proper rest."

"Ah... well, everyone, don't worry about me, I'm not tired at all right now!" Ritsuka even waved her fist, indicating that she didn't need to worry at all.

"Tsk... Damn it." Suddenly, Nian Zhuo and Mordred looked ahead at the same time. The clattering sound of machinery started up again, and countless automatons ran out of the thick fog once more.

"Here we go again." Mordred gestured towards Mash and went to greet them first.

“Leave this battle to you guys, Ryotaro. Momotaros looks like he’s about to explode with pent-up energy.” Nencho pulled Ryutaros and Momotaros apart from their fight and pointed to the enemy emerging from the mist. “Hurry up~ Mordred will take everything if we don’t hurry.”

"Oh! Let's go! Ryotaro!" Immediately afterwards, Momotaros's body turned into specks of red particles and merged into Ryotaro's body... As for Ryutaros? He was directly pushed back into the Time Train by Momotaros.

"You two..." He temporarily switched back to Ryotaro's personality, scratched his head helplessly, but still put the belt on his waist and pressed the red button at the top.

"Oh! Here it comes!" With his hair dyed fiery red, Momotaros's voice, brimming with fighting spirit, came from Ryotaro's mouth as he manipulated his body, slid the ticket across the drive at his waist.

The train tracks circled around Ryotaro again, first transforming into a platform, and then the red and white armor pieces merged into Ryotaro's body one by one.

"I'm here." Having assumed a fighting stance, Momotaros leaped into the pile of automatons, his holy sword slicing through them with red electricity.

Amidst the continuous battles, Nencho protected Ritsuka and Mash as they advanced along the path pioneered by Mordred and Momotaros.

There were more enemies this time than last time. At least Nianzhuo and the others encountered more automatons as soon as they went down one floor of the stairs, and they even had time to let Ritsuka rest for a while before setting off again.

However, after Momotaros kicked the last automaton down the stairs and smashed it to pieces, silence returned to Nianzhuo and his group.

"Phew~ That's really refreshing!" Wiping the sweat from her forehead, Mordred realized that the continuous slashing was indeed taking a toll on her body. Looking at the unfamiliar walls around her, she turned to Mashu and asked, "Um... by the way, what floor are we on now...?"

“We’re already on the fourth floor. We just came down the stairs.” She turned her body slightly to the side so that Mordred could also see the stairs not far behind Mash. “Our current location is… about a hundred meters underground.”

"Ugh~ We've already come this far~" Completely oblivious to this, Mordred, who was completely absorbed in the battle, impatiently scratched her head. "Won't it be a real hassle to get back like this~"

"Hmm... I guess... Mashu couldn't think of a solution for the moment, so she could only nod in frustration.

"Ah... everyone, let's be more careful." Ritsuka, who was on Nianzhuo's back, suddenly spoke up and pointed her index finger forward.

"They look like enemies again, and behind them... there seems to be a faint light."

Following Ritsuka's index finger, everyone saw even more automatons than the previous two times, and purple light emanating from behind them from time to time.

"Ha, looks like this is the final battle!" Crimson lightning finally crackled along the blade, and Mordred only now truly took it seriously. "Let's hurry up and finish packing, and get ready to check out that steam engine!"

With a powerful stomp of his foot, crimson lightning sliced ​​through the air, sending the heavily armored knight into the enemy ranks. Immediately afterward, crimson lightning exploded amidst the enemy crowd.

"Ryotaro-senpai, and Mashu, you two go too." Nianzhuo tugged at Ritsuka on his back and looked at Mordred in the midst of the battle ahead. "It wouldn't be good if Mordred were in any more danger. I'll protect Ritsuka for now."

"Oh! Then I'll leave it to you! Nian Zhuozi!" With a cheerful wave of his hand, Momotaros also let out a battle cry and charged into the army of automatons.

"Yes, thank you, Mr. Nianzhuo." With that, Mashu pushed the shield even more directly, knocking away all the automatons blocking her way.

"Mr. Nianzhuo, what kind of enemy do you think we'll face this time?" Ritsuka asked curiously, pointing at Nianzhuo's silver facial armor as she lay on his back.

"...An enemy weaker than me awaits us." Nencho said with utmost confidence, flicking Ritsuka's nose.

As they fought their way in, no matter how many automatons they encountered, they were all shattered before the three of them. Nian Zhuo and his group had undoubtedly entered the mysterious place that emitted a purple light.

As soon as you enter, what comes into view is a desolate plain, and a huge man-made building standing on the plain, spewing out hot white steam like a lurking monster.

However, this scene was all too familiar to Ritsuka, Mashu, and Nenjo.

"...It looks just like the Greater Grail from Fuyuki. This is truly... astonishing magical power." The gusts of wind that rushed towards them carried incredibly violent, highly concentrated magical power, causing Mashu to grit her teeth. "Even within the magical mist, I can strongly feel this immense magical power; it's such a massive magical core..."

The building atop the only peak on that plain was the source of that purple light—a huge, constantly moving circular steam engine.

“You don’t need to say more! I can observe it from here!” With her heart pounding in her chest, Mary’s fingers slid across the control panel in front of her. “There’s no mistake, the source of the demonic mist is that huge thing!”

“This is the first time I’ve ever seen such a huge machine.” Even Mordred had to admit, “Angolboda is indeed worthy of the name of a giant.”

"Unfortunately, this isn't Fuyuki, and that annoying guy isn't here either." Nianzhuo cracked his knuckles, but didn't dare to relax for a moment as he looked around. "Everyone, let's all stay alert, the final enemy is right here."

“Yes.” Mordred nodded, lowered the blade from his shoulder, closed his eyes, and then opened them again, his green eyes filled with hostility. “Although I still want to take a closer look—it seems the final boss has already appeared.”

A figure slowly appeared in front of Nianzhuo and the others.

The man with deep blue hair, two strands hanging down in front of his forehead, wearing a long robe and frowning, looked at Nian Zhuo and the others in front of him with annoyance.

“…Hiss.” Nian Zhuo looked the other person up and down and suddenly felt that he looked a bit like…Agravure, who had appeared in Chapter Six, but his hair and expression were like Cú Chulainn and Diarmuid.

"—Strange." The man clapped his hands, looking at them with interest. "What's strange is that Paracelsus actually spoke too harshly; evil deeds will inevitably be thwarted by those who do good." He looked behind him at the enormous 'steam monster' atop the mountain.

“Angolboda, as a massive steam engine, is both our evil form and our hope.” Raising an eyebrow, the unknown man conjured a black sphere of light in his hand. “Your journey ends here. Today, good will be driven out by our evil.”

“I say, you guys really are a bunch of blabbermouths.” Mordred responded impatiently, crimson lightning clinging to her blade. She glared at the man with displeasure. “Stop talking nonsense. It’s your lives that will end here.”

"Oh—?" The other person looked at Mordred with a hint of scrutiny in their eyes.

The demon Barbatos has appeared!

The blue-haired man stared at Mordred and then laughed.

"Hoo hoo hoo... Hahahahahaha!" The man frantically covered half his cheek, his gaze unfocused and scattering everywhere. He pointed his index finger at Mordred, laughing so hard that his body trembled. "I... I know you, hahahahahahaha!"

"Tsk, damn it, what's so funny?" Mordred clicked his tongue in annoyance, his anger instantly ignited by the other party. He grabbed his sword and was about to rush over and cut off the guy's head, but Nianzhuo pulled him back.

"Hey! Nianzhuo!" Struggling to break free, Mordred glared at the silver mask and said angrily, "Let me go! I'm going to chop this bastard into pieces!"

"Don't rush, Mordred." However, Nian Zhuo stared intently at the man laughing maniacally, and sensed a slight threat from him. "This guy is the final boss."

"Huh? Him?" Mordred was taken aback at first, but she calmed down and, though she was disdainful, she still carefully examined the man in front of her.

The maniacal laughter finally ended, and the man's face was expressionless, as if that morbid smile had never belonged to him at all, and he returned to his indifferent expression.

“Heroic Spirit, Mordred.” Gritting his teeth, he uttered Mordred’s true name, “The thirteenth Knight of the Round Table, the infamous King of Betrayal…” He closed his eyes, spread his hands, and spoke casually.

"I thought you would be on our side. It's ironic that you've turned into a benevolent hero."

"You're... the mastermind behind Project [Magic Mist]... [M]?!" Not merely listening to his words, Ritsuka was also secretly scrutinizing this seemingly abnormal man. "Just who are you?!"

"Hmm... I almost forgot I haven't introduced myself yet." The man bowed slightly, but his face remained expressionless. "My name is Machiri Zorgen. I am the initial leader of this [Magic Mist Project]."

"It's to completely destroy this era—to destroy this Fourth Singularity! A magician who plans to corrupt the entire land of Britain with magical mist!"

“It’s the whole of Britain! Damn it, it’s not just London!” Biting her thumb, Mary immediately turned to the computer next to her and tapped the keyboard, searching for information on a man named Machiri Zorgen, but to no avail.

"Seriously... should I call you incredibly stupid, or incredibly ambitious...? This kind of thing is inherently extremely difficult." Mary raised an eyebrow in annoyance, her mood darkening further at the fact that she couldn't obtain the information.

"Of course, simply destroying London is far from enough." Hearing Mary's words, the man also presented his idea of ​​destroying the era as simple intelligence. "Only by completely destroying this era can we eliminate the foundation of human reason. This is our king's wish, and it is the only action we can take after our final realization."

“My King…! He said my King…!” In Mashu’s eyes, the cold but raving man before her overlapped with the figure of the professor in the dark green robe. “Master, and Mr. Nianzhuo, this person is with Leif Lenor…?!”

"Who exactly is this 'King' you speak of?!" Ritsuka shouted at the other person. "And are you an accomplice of Rafe?!"

If the other person reacts to the name Rafe, then it proves that this guy is one of Rafe's kind.

"Hahahaha! At this point, there's no need for further words!" However, the other party didn't answer Ritsuka's question. Instead, he turned to the side, arms outstretched, looking at the massive steam engine on the high platform behind him with a maniacal laugh. "Angolboda has gone out of control! Enough to truly activate the demonic mist that fills the entire city! Powerful Heroic Spirits will surely manifest here! Haha, hahahaha...!"

"That heroic spirit's attack! It can make this demonic mist even more powerful! And thus spread throughout the entire world!" Although he didn't know who the summoned heroic spirit was, he clearly didn't care about such things. "Then, then everything will come to an end."

The massive steam engine behind the man—Angolboda—was emitting an increasingly alluring and dazzling purple light.

Gradually, the magical mist that had enveloped the entire city of London seemed to come alive, slowly gathering towards the sky above where Angorboda was located. However, Nianzhuo and the others underground obviously could not see this scene.

A magical mist enveloped the area, forming a giant sphere, and the magic that enveloped the entire city of London was also gathering frantically.

"Come on, look!" The man's lips curled into a grin, his trembling voice conveying his excitement. "The heroic spirit we've been eagerly awaiting will soon emerge from the Demonic Mist of China! One of the Star Pioneers, befitting the so-called final act of human mythology! Or perhaps, the Star of Radiance—"

"How could I let you succeed!" Immediately afterward, a figure suddenly appeared in front of the man. Within the constantly rotating dark golden time ring, Nian Zhuo's figure, wielding the strongest ultimate sword, was revealed.

"Ah...ah?! That guy! How did he rush up there so quickly?!" Mordred was stunned at first, then realized that the guy who was holding her down was running faster than her. "Well, I'll join in too! I've been wanting to get rid of you for ages! I will never forgive you for ravaging Britain before me! Even if you're just a human!"

"...!?" Mash, who was about to follow, stopped in her tracks, staring at the man in the distance who had suddenly widened his eyes and was staring at the blade that Nian Zhuo was swinging at her. "He... isn't he a Servant...!?"

"Human or Heroic Spirit!" Nencho, now in Zi-O II form, gripped the sword hilt tightly and slashed towards the opponent's neck. "All I need to know is that you are an enemy! That's enough!"

"...!" The man rolled to the side, dodging Nian Zhuo's blade in an awkward posture, but his robe was covered in dust, making him look somewhat disheveled.

"Why did you do this! Machiri Zorgen! Why do you want to destroy the era you live in—" Mashu questioned the man. In her eyes, he was a living, breathing human being, yet he wanted to destroy the world he lived in. This was clearly very abnormal.

"Of course I tried to resist... but it was all in vain." Only now did the man appear surrounded by an aura of defeat, looking somewhat dejected. "Even if I wished to save all living beings, the world where humanity should have lived has already been burned down. Whether in the past, present, or future, my king has already decided that no existence will be tolerated. — Everything must be destroyed before it's over."

"..." After swinging his sword but being dodged by the other party, Nian Zhuo did not immediately pursue, but observed that "the aura on this man's body... has begun to become chaotic."

"Ah, ah! The decree has been issued, the king is tired of this ugliness, tired of all existence!" He placed his hands on his chest and clenched them tightly. "Then, now that things have come to this..."

“No, there’s no need to say any more.” Machiri’s furrowed brow relaxed, and she sighed. “We will use the power of our King to utterly annihilate you. You will die before you even see the last heroic spirit. Descend from the Void of Destruction! Our Demon God—!”

He raised his hands high, and magical power surged from his body, converging on the purple magic circle in mid-air.

"What—! Quick! Mordred! Attack!" Just one glance at the magic circle made Nian Zhuo's brow twitch slightly. He quickly called to Mordred behind him, and together they gripped their swords and charged toward Machiri Zorgen.

"Ah...? Oh!" Startled at first, Mordred followed Nianzhuo's gaze and immediately looked away when she saw the huge purple magic circle in mid-air, covering her forehead. "Damn it... that magician...!" While covering her forehead, Mordred immediately grabbed her sword with one hand and followed Nianzhuo towards Zorgen.

"Damn it, damn it! Was that guy's aura just for gathering that thing?!" Moving forward at high speed, Nian Zhuo caught a glimpse of the girl following behind him out of the corner of his eye and stopped worrying. He accelerated and swung his sword toward Machiri's neck.

"Haha, hahahaha!" However, he paid no attention to the sword blade he swung, but just trembled as he looked at the purple sphere of light in the center of the magic circle that had already formed in mid-air. "It has descended... it has descended...!"

With a loud thud, the purple orb in mid-air transformed into a cylindrical stream of light and descended, engulfing Zorgen's body.

At the same time, the beam of light crashed to the ground, and the resulting purple shockwave immediately struck Nian Zhuo and Mordred, who were rushing over.

"—!" The two figures froze simultaneously, then were blasted away by the purple impact, their bodies shooting backward.

"Mr. Nianzhuo! Mordred!" Mash wanted to go, but the purple impact came immediately, and she could only hold her shield in front of Ritsuka.

With a hissing sound, Mash braced herself against the shield and took several steps back, finally managing to withstand the oncoming impact.

As soon as the impact subsided, she immediately looked towards the center, searching for Nian Zhuo and Mordred.

The original plain became increasingly chaotic, with the purple impact leaving numerous cracks in the earth. At the central location where Zorgen was, the purple magic circle had disappeared, leaving only a vast amount of thick fog, making it impossible to see what was inside for the time being.

"Cough...cough cough cough!" A violent coughing sound came from behind Mashu, accompanied by a lot of dust and dirt. Nian Zhuo's figure was finally revealed. The Zi-O II that was originally bright silver was now a bit dirty and messy, and Mordred, who was also a bit disheveled, was also revealed under Nian Zhuo.

"Huff... huff..." Still looking somewhat surprised and unsettled, Mordred opened her eyes wide, as if she was still frozen in the moment when the astonishing impact had struck.

Fortunately, Nianzhuo had run farther than her and was able to use the impact to block her in front of her; otherwise, this girl, whose mind was full of fighting, would have been swept away by the impact.

Brushing the dust off his clothes, Nian Zhuo half-squatted on the ground and waved to Mordred.

"Hello, hello? Are you there?" Seeing the other person's somewhat listless emerald green eyes regain their light, Nianzhuo tapped his slightly aching side.

"Th...thank you..." Mordred wasn't stupid. When the impact came, she knew that if Nianzhuo hadn't blocked it for her, she might have been swept away from here.

"Alright, alright, it's good that you're alright. You'd better be more careful next time." He tapped Mordred's forehead and then suddenly tapped Nianzhuo's back with one hand.

“Nianzhuo…sir…” It was Mashu’s voice, but for some reason it trembled slightly.
