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

With a buzzing sound, a magenta card appeared in his hand.

"I see." Nian Zhuo instantly understood what the card in his hand was. "These specks of light mean the experience card of the knights' ultimate power that I currently possess." Then, with a thought, the card in his hand turned into specks of light again and returned to the bottom of the statue.

"So, what is the degree of this reversal..." Nian Zhuo then closed this option and opened another option below.

Then, the light screen in front of them suddenly disappeared, and what followed was pitch black.

"..." After seeing the scene on the screen, Nian Zhuo couldn't bring himself to laugh.

It was an inverted black tower, and I was at the very top.

The deeper you go, the more profound, heavy, and suffocating the black becomes.

The first floor is the Black Tower, which resembles Evolto.

The second layer is a clock wheel bearing the mark of Cronus.

The last layer is a crown.

Beside him was a face with a ferocious, beastly grin.

“This is really—” Nian Zhuo looked at the Black Tower in front of him, but he couldn’t keep calm. “It’s not a change that can make people feel happy.” Then, his eyes widened a little, as if he had made some strange discovery.

On this inverted black tower, below it, on the towers of Evolto and Chronos, there is a red footprint.

"What is this again—?" Nian Zhuo was still in a state of shock from this function, asking the system in his mind.

"This is the level of the dark side of the host's heart that he has reached before." The system's voice also became very soft, as if even he was afraid of this function.

"It is because the host used the power of Evolto and Kronos that there are these blood-red footprints on their towers." The system's voice reassured Nian Zhuo slightly, as he had thought that this meant he would have to fight them again.

"—However, more than that, host, I would prefer you to pay attention to this side." Then, the system's voice came from beside him, drawing Nian Zhuo's gaze in that direction as well.

It was something like a thermometer, with a silver dot at the very end, 0.

At the very top is the number 100; it seems this is the device used to detect the distance between Nencho and that guy...

However, what caught Nianzhuo's attention even more was a flashing light at position 25.

"System, what does this mean?" He tried to touch the point of light, but the moment his fingertip touched it, it went out completely, as if time had run out. "What exactly is this point of light...?"

"—This is the level you once reached." The system's voice rang in Nian Zhuo's mind several minutes later. "I never expected that the host would have experienced death while the system was in hibernation."

"I see. So, before I died, I already had a 25% similarity to that guy?" Nian Zhuo nodded, his gaze shifting back to the inverted, dark tower.

The top layer has been illuminated by black and white patterns—the power of evolto.

The second layer is enveloped by dark green and black clock hands—the power of Cronus.

The third floor, although still completely dark, has its Eternal sign lit up.

“…” Nian Zhuo opened his palm, and then the white and blue watch face fell into his hand.

"Host, are you really going to do this?" Watching Nian Zhuo clench and unclench the watch face in his hand, then clench it again, the system couldn't help but ask him, "With your current power, host, you don't really need the power of these knights with their side effects, do you?"

That's not the problem; Nian Zhuo is quite clear about it.

He now possesses the power to continue peacefully, but he did not take out his watch because he desired the power of the Eternal.

The Great Way of Self-Discipline—the holder of this power, Nian Zhuo wishes to meet him.

He, who was once human, made a declaration that all humans are demons.

Even though he had harmed the city, Philip and Shotaro couldn't bring themselves to hate him until the very end.

"So, it seems like this is another gamble." Nian Zhuo closed his eyes, then, as if making a decision, turned the white dial.

"After all, having just witnessed the beauty of humanity, I simply can't leave him alone." A bitter smile appeared on Nian Zhuo's lips as he pressed the button above the dial.

A pale blue hurricane flew out from the dial, transforming Nian Zhuo's body into a crystal blue data stream that flew into it.

His vision blurred for a moment, and when Nianzhuo opened his eyes again, the scenery around him had completely changed.

He knew this place. Nianzhuo looked at the huge windmill slowly rotating beneath his feet.

—The City of Wind. The place Philip and Shotaro once took him to.

But now, Nian Zhuo is facing something completely different here: a man with his back to him.

The eternal mockery of the human heart, the timeless praise of the human heart.

Looking at the figure not far away, Nianzhuo's expression gradually became serious.

That is the target this time, the Eternal Transformer—Dao Keji.

"So that's how it is. Even after my death, I cannot find peace." With a slow sigh, the light brown man in a black and red combat suit slowly turned around. "Then, what is it this time?" He flexed his wrist, which was covered by a black glove.

“The Great Way is about self-discipline. I’ve come here specifically to see you.” Nian Zhuo met his gaze, then quietly clenched his fist.

The oppressive aura emanating from the man before her remained even without his transformation.

"Oh~?" Clearly, the man in front of him raised his eyebrows in surprise, but the oppressive feeling did not disappear; instead, it became even more serious. "That's quite an unexpected answer. Why would you, who are perfectly healthy, come looking for someone who can't die?" A vortex of azure blue condensed in his right hand, and he held a white and blue watch face in his hand.

"Isn't this what it's all about?" Da Dao Keji shook the watch in his hand at Nian Zhuo with great interest. "I never thought that the power of eternity could be taken away with such a small thing. Humans are really creative."

“I told you, the purpose of my visit is to see you, not your thing.” After his gaze lingered on the watch face for a few seconds, Nian Zhuo turned his attention back to Da Dao Keji.

"Ha, interesting." Holding the watch face in his hand, Daido Katsumi stared at Nencho before him. "So, you wanted to see me?"

"Ha, of course it's nothing." Nian Zhuo shook his head, but then took a few steps forward. "I just wanted to see what the immortal man who said that all humans are demons looks like."

"—" Dao Keji's eyes widened slightly, seemingly quite surprised. "Hmph, another one who's seen my past? I never expected my experiences to be so interesting."

"Another one...?" Nian Zhuo muttered with some doubt.

“That’s right.” However, Daido Katsumi did not hear Nian Zhuo’s muttering. He spread his arms, and his figure cast a huge, distorted shadow on the ground in the night of Fudu.

"All humans, including you, are demons!" Then, a sinister smile appeared on Da Dao Keji's face as he pointed at the stunned Nian Zhuo and uttered words filled with hatred, "Humans are such greedy creatures!"

“Those who are different must be eliminated, and those who do not conform to your truth must be suppressed! You may even kill your own comrades.” The words of the Great Dao of Self-Discipline contained emotions that Nian Zhuo could not comprehend.

No, he could understand that the man in front of him was angry, but he couldn't sense the end of that anger.

What kind of despair must he have experienced to become so filled with hatred for humanity?

“So, I chose you.” Suddenly, Da Dao Keji extended his index finger and pointed at Nian Zhuo.

"What?!" No, Nianzhuo sensed something was wrong.

Since the two had never met before, how could it be said that he was chosen?

“…No, that’s not right, it should be your future self.” Looking at Nian Zhuo’s bewildered expression, Da Dao Keji finally realized, “That power is really strong~” With a contemptuous smile, he looked at Nian Zhuo, whose face suddenly darkened.

“With a wave of his hand, he destroyed the entire Fengdu, and even completely destroyed the world that belonged to those two guys.” Narrowing his eyes, Dao Keji seemed to see the dark figure overlap with the one in front of him. “After that, he fulfilled my long-cherished wish, and even promised to destroy all of humanity, so I handed over my power to him.”

"What—" Just hearing Da Dao Keji's description, Nian Zhuo already felt a faint sense of fear. "That guy destroyed Fengdu in an instant..."

"So you're just like me, Nianzhuo!" The demon grinned maliciously as it stared at the wavering Nianzhuo before it, its arms outstretched. "You and I are both monsters who have abandoned our human identities!"

"However, looking at you now, you're really boring, aren't you?" Closing his eyes, Da Dao Keji shook his head helplessly.

"Then let me take you back to that hell."

Then, he looked at the white and blue watch face in his hand, on which his familiar face was flashing.

"Since this is my power, then logically I should be able to take it back." He turned the dial, and then Daido Katsumi pressed the knob on top.

"What!" Sensing an ominous premonition, Nianzhuo rushed forward towards Da Dao Keji, trying to stop him.

However, it was too late.

The blue vortex instantly swept everything away, half of the red driver wrapped around Daido Katsumi's waist, and at the same time, the surging blue vortex instantly sent Nencho flying.

"Cough!" He was blown away by the vortex and slammed hard into the windmill, then crashed heavily to the ground.

Nian Zhuo struggled to his feet and looked at the Great Dao Keji, which was enveloped in the vortex not far away.

"What exactly... do you want to do?" His vision blurred for a moment, but Nianzhuo still managed to get up from the ground.

"What do you want to do? That's a good question." Daido Katsumi smiled, then made a fist with his right hand.

"Give me eternal slumber, Nianzhuo." Then, a snow-white memory appeared in Da Dao Keji's hand.

"Eternal—!" Instantly recognizing the true form of the memory, Nian Zhuo knelt on the ground, unable to stand. "The Great Dao of Self-Discipline! You—"

"Ha, remember my name." Then, he pressed the memory in his hand.

“Eternal—!” Insert it into the Lost Driver at your waist.

"Come on, enjoy the pleasures of hell!" Pressing down on the memory device at his waist, Katsumi Daido pried open the red wing at his waist. "Henshin—!"

Layers of snow-white fragments emerged from the air and merged from his feet into the body of Dao Keji.

The red flames in his hands were gradually enveloped by blue vortexes, eventually turning into a deep blue like the ocean.

A long, jet-black cloak draped over his shoulders, casting a long, dark shadow.

Between the two snow-white horns on its head, a bright red gemstone is engraved.

Golden eyes gleamed as they gazed at Nianzhuo, who was kneeling on the ground.

"How is that possible? How can you transform in the Mirror World as well?" Nezuko had never seen either Evolto or Dan Masamune using the Driver when he entered their Mirror World, so he naturally assumed that Daido Katsumi was the same.

"Ha, you still think you entered this world willingly?" He chuckled mockingly, then Da Dao Keji opened his arms, and the windmill beneath his feet began to spin. "Wrong! I pulled you into this world willingly!"

"How is that possible—you shouldn't have that ability!" The sharp pain in his waist had subsided, and Nianzhuo slowly stood up.

Memories from before entering the world of the Mirror of Self-Discipline are gradually becoming clearer.

"...I clearly pressed the button and the blue vortex appeared—" Finally, realizing the source of the slight abnormality, Nianzhuo's eyes widened.

"The sound effects... didn't play?!"

"So you finally noticed, monster!" Without giving any chance, the white knight swept aside his black cloak, gripped a short sword in his right hand, and charged toward Nianzhuo.

"Damn it, if you can do it!" Nian Zhuo closed his eyes and recalled the power that belonged to him.

“Then—I can do it too!” Then, a purple light appeared in his hand, and the silver Time Driver appeared in his hand.

Also falling to the ground were Nian Zhuo's silver watch face and... a purple and green watch face.

"There's only one left, is it the W dial?" Picking up the two dials and the driver, Nianzhuo looked at Daido Katsumi attacking him and finally made up his mind.

"You bastard, I'm going to beat you right here!" Then, Nian Zhuo placed the Time Driver on his waist and turned the two dials in his hand.

"Zio——!" "W——!"
