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

"Don't lose, my servant!"

--The training room at this moment--

Equipped with the Build armor, Nian Zhuo experienced a significant boost in both his attributes and Noble Phantasm. However, the sheer power of Kilshtaria before him truly astonished him. (Even with the Build Watch, he couldn't easily overpower him; this man's strength seemed beyond what a human mage could achieve.) Nian Zhuo was still pondering countermeasures, but his hands continued their relentless attacks. Incidentally, Zi-O no longer used the Time Limit Sword; instead, he wielded a golden-and-white rapier in his right hand. A storm of thrusts continued towards Kilshtaria, shattering the shield in front of him without even a chance to block it. Then, in the blink of an eye, it was reconstituted by the leader's massive torrent of magical energy.

At this moment, Kilshtalia laughed wildly, as if she had encountered something new and exciting. "Ah, this is the feeling! I haven't met anyone I can fight in a long time. You really are a man worth my all-out effort! Nian Zhuo!!!" As she spoke, Kilshtalia was caught off guard and was once again knocked away by Nian Zhuo, widening the distance between them.

Then, Kirshtalia stood up, and an even larger torrent of magic surged from his body.

"Although I originally intended to hold back my strength, this man is worth my all-out effort!" Kilshtalia laughed, his magical power coalescing into a golden whirlwind that enveloped him.

"That's a high-density magic barrier!" The researchers exclaimed, their eyes wide. "This is the first time I've ever seen such a high-density magic barrier!"

With a wave of his hand, the blond man unleashed several more magical energy beams, each now leaving deep marks on the floor, forcing Nian Zhuo to passively defend against them.

"No matter what, this power is too great!" Watching the magic cannon fire sparks and make soft crackling sounds from his internal organs and bones as it struck his body, Nian Zhuo felt an unprecedented sense of unease. "This guy! Like this!" He then deflected the next oncoming cannon shot and leaped high into the air.

Subsequently, a function curve linked the paths of Nianzhuo and Kirshtalia.

"What? This... this can't be broken free?" Upon discovering that the curve was firmly binding her, Kirshtalia contracted the dense magical mist around her body, condensing it into a high-density magical shield.

"VORTEX TIME BREAKE!"

Accompanied by a sound effect, Nian Zhuo thrust his right-hand turbine straight down, colliding directly with the high-density golden shield.

With each thud, a crack appeared in the golden shield in front of Kilshtalia, then two, three, and more and more cracks appeared on the shield. With a sound like shattering glass, Kilshtalia was blasted away by the relentless turbine.

"Cough, cough, cough," Kilshtalia struggled to her feet, her face gradually contorting into a grimace. "Ah! Now is the time to show my knowledge, my ability, for I am the one who controls the planet. Now, let me offer my utmost respect to this battle between us!"

Kirshtalia froze, then golden magic gathered on his star-like staff, unleashing waves of energy that swept through the entire training room with terrifying force.

"Kirshtalia's magical energy concentration has reached the level of a Noble Phantasm's true name release! A collision between the two Noble Phantasms will destroy the entire laboratory! Stop them immediately!" The researchers shouted, pleading with Director Marie to halt this superhuman duel. Marie, her face grave, pressed down on the microphone in front of her.

"You two! Stop—" Nian Zhuo spoke up before she could finish.

"Don't stop, Master! This is a duel between him and me, a duel where we stake our beliefs!" Nian Zhuo flashed a card in his hand, followed by a burst of multicolored light that enveloped him.

(Congratulations, host, you now possess the power of the Build Genius Form. Time limit: one minute.) The system's emotionless voice echoed in Nian Zhuo's mind. However, Nian Zhuo had no time to care about anything else at this moment. His eyes were only on the man standing opposite him, whose blond hair flowed freely, and who was chanting ancient, mysterious incantations that were not understood by others.

"The shape of a star, the shape of the sky."

"Everything is as I wish"

"I, too, am one who controls the stars."

"I offer my highest respect to the adversary before me."

"Stars! Beams of Light!" Kilshtalia roared, unleashing all the magic she had accumulated in one breath.

The golden starlight shot towards Nian Zhuo, scorching the ground in its path, and hurtled away with an invincible aura.

"Then I will also offer my ultimate strike!"

"I am the Demon King's understandr!"

"Know the unknown past!" "Envision the unobservable future!"

"He aspires to become the most benevolent, virtuous, supreme, and powerful king!"

"Tokiwa Sougo!"

In the same posture, Nianzhuo leaped high into the air once more, his genius form tracing a rainbow-like streak of light in the sky.

The same function trajectory reappeared, firmly connecting the two together.

"The same tricks! You can't beat me twice!" Kirshtalia roared, looking up at Nencho leaping high above.

"Genius Time Break!" Then, with a rainbow-like streak of light, Nian Zhuo kicked down, colliding with the golden meteor.

Surprisingly, Nian Zhuo's figure was not swallowed by the meteor; instead, it continuously suppressed the meteor's advance.

"My magic is being decomposed!" Kilshtalia was astonished by this fact. He could feel his magic constantly evaporating and becoming part of the atmosphere, originating from the rainbow-like light of Nian Zhuo!

"Aaaaaah!" Nian Zhuo roared, continuously exerting his power, and then, after a long stalemate.

The meteor was finally swallowed by the rainbow, and the multicolored streak of light leaped down, followed by the unstoppable Nian Zhuo rushing towards Kilshtalia.

A genius is unstoppable (author's voiceover) {humorous}

Then, Kirshtalia watched helplessly as the rainbow-like streak of light drew ever closer. No matter how many defensive spells she condensed, they would be instantly destroyed by the opponent. Kirshtalia closed her eyes, awaiting the final blow.

"To lose to the rainbow in the end is quite a sight," Kirshtalia thought to herself, preparing for the final onslaught.

However, the expected pain did not occur. He opened his eyes and looked at Nian Zhuo, who had stopped just a step in front of him. The man opposite him was still radiating rainbow-like light, but he simply stood there, not making a move to defeat him.

“I told you, I only agreed to fight you to give you a warning,” Nian Zhuo said with a hint of helplessness as he gently touched Kirshtalia’s forehead. “So, are you going to admit defeat now? If you don’t, I’m really going to kick you.”

Kirshtalia looked at the man in front of her and finally had no choice but to raise her hands, declaring her defeat. "Fine, I admit defeat."

Nian Zhuo raised his right fist high, a gesture that symbolized victory!

Outside the door, Miss Mary, who had been unable to contain herself any longer, rushed in and hugged Nian Zhuo. Nian Zhuo could only helplessly indulge this little princess's audacity. After all, seeing her slightly reddened eyes, Nian Zhuo felt a pang of guilt (this time things had really gotten out of hand). Thinking this, however, the system's notification made him smile again.

"Congratulations, host, on completing the mission: The One Who Controls the Stars and the One Who Masters Time."

Reward: Ex-Aid watch face x1 (to be distributed within 24 hours)

P.S.: I suggest you get some rest afterwards, as you will feel extremely tired and stressed later.

"???" Nian Zhuo, who was holding Mary, was completely bewildered. Pressure? What is this? Then he let go of Mary and walked towards the door.

As soon as he stepped outside, his Build Genius form dissipated, and he couldn't even maintain the Zi-O basic armor. Nian Zhuo hid in a deserted corner and knelt on one knee.

"Ha-ha-this, this is!" Nian Zhuo clutched his chest and asked the system, "System, what's going on?!" "Reporting to the host, your physical stats are already inadequate, and now you're being forced to transform into a knight's third form. Even for a short time, this will put a huge burden on you, so it's inevitable that you'll feel pressured," the system's emotionless words echoed in Nian Zhuo's mind.

But for Nian Zhuo now, this was like a hammer blow to the head. He felt as if his whole body was about to crack open; the immense pressure made it hard to breathe, and finally, his vision went black, and he fainted.

The next moment, a little girl in a white coat appeared at the far end of the corner. Her purple hair covered one eye, and she stared expressionlessly at Nianzhuo lying on the ground. After a while, she slowly spoke.

"At this point... the doctor said we should carry him to the infirmary." With that, the purple-haired girl laboriously lifted one of his arms and draped it over her shoulder, slowly making her way towards the infirmary.

"Alright, Mashu, you're struggling too much on your own. Let me help you." The intelligent beauty with an eye patch blocking Mashu's path was none other than Ophelia.

Ophelia gently draped Nianzhuo's other arm over her shoulder, looked at the unconscious, unguarded man before her, and sighed softly.

"You bastard..." Remembering the rainbow-like streaks she'd seen on the screen, she clenched her fist slightly.

"I will never forgive you..." With a hint of shyness, Ophelia and Mashu walked together toward the medical room.

――――The main control room, just finished with observations――――

Looking at the ever-increasing pile of reports in front of her, Da Vinci's face twitched again. "How much magic will it take to fix this? The extra money will be deducted from Tokiwa Sougo's salary. I'll make him owe me a lot, a lot of money, and then I, the omnipotent one, will research his Noble Phantasm. Hehehe, hehehehe." A cryptic laugh escaped her lips; the shrewd businessman's true nature was revealed. Then, another report handed to her by the researchers caught her attention.

Let me see—

"Yes, the latest data on Sougo's rainbow-like form is..."

"Strength reached A+, that's interesting."

"Agility and durability are both A+, oh~ this is getting more and more interesting!"

"My magic power is still C. It seems I really don't have any magical potential. What a pity~"

"But why has Luck actually decreased to C+? Could this be the price to pay for increasing other stats?" Da Vinci stroked his chin, expressing his doubts about Luck, the only attribute that decreased after the transformation.

—Can you guess why?—

A meeting between the King of Time and the strongest gamer (part-time pediatrician)

With great effort, Nian Zhuo opened his eyes and found himself atop a tall building.

"Could I have time-traveled again?" Nian Zhuo scratched his head with difficulty, accepting the fact that he was on top of a building with unusual speed.

"Host, you are currently in the world of Kamen Rider Ex-Aid in 2016. Because you lost consciousness, the newly acquired Ex-Aid watch automatically pulled you into this mirror world, and even the system cannot stop it. Please be careful, host." The system's voice rang in Nian Zhuo's mind again. Although he was puzzled as to why he was pulled into this world without actively connecting, the sudden sense of danger behind him forced him to return to reality, rolling on the ground to dodge.

"Bang—" The spot where Nian Zhuo had been standing had been hammered into a large crater. Nian Zhuo's face stung from the flying shards of stone, but when the dust settled, what remained was a somewhat comical-looking, bloated, dark purple knight.

"This!!! How is this possible!" Nian Zhuo recognized the knight's appearance and form at a glance. "How is this possible! This is the Mirror World of Ex-Aid! Why is Dan Kuroto! Your God Limit here?!" Nian Zhuo shook his brain, which had temporarily stopped thinking due to shock, and shouted, trying to understand the current situation.

"We are also Ex-Aid, just as you said, we are all knights in the Ex-Aid world! Regardless of good or evil! Regardless of life or death! Regardless of morality!" Dan Kuroto said with a maniacal laugh, even covering his head with one hand while laughing. "Ahhh--you have a really good expression. Are you so concerned about Emu's safety? Or are you just worried that you can't get your Ex-Aid power?" Dan Kuroto took out something round and waved it in his palm at Nencho.

When Nian Zhuo saw the pink watch face with green trim, his clenched fists tightened even more, his eyes bloodshot, and he angrily exclaimed, "You bastard, what did you do to Yong Meng!"

Staring at the impotent rage of the man who had suddenly intruded into this world, Dan Kuroto—no, God Limitless—was momentarily stunned. Then he let out an even more maniacal laugh, "Hahahaha—"

Whether the scene was too comical or not, Shen Jixian almost fell backward from laughing. Without further explanation, he simply shrugged.

"I'm not acting anymore, I'm laying my cards on the table! This is true divine talent, hahaha—" "You bastard!! Dan Kuroto!" Struggling to his feet, Nian Zhuo clenched his fists and charged towards the limits of divine power, wanting only to smash that detestable laughter. Having already learned from the system's reply that he couldn't die in this mirror world, Nian Zhuo finally let go of his burdens and acted as he pleased.

"Hmm~ As a clown, it's quite a farce." Dan Kuroto opened his arms, ready to receive Nencho's attack.

"Ah—" Nianzhuo watched the distance between them shrink, and the longing in his heart grew stronger.

(Power! Power! The power to defeat that man! The power to surpass the limits of gods! The power to allow myself to achieve what I want! Anyone, lend me that power!! I can't do it now. Without the driver, I can't transform, and even if I did, I definitely couldn't defeat that bug. So, please, anyone, lend me that power.) Thinking this, Nian Zhuo felt a faint electric current traveling through his spine, extending along his nerves and finally connecting to his hands. "This is—"

――――World Dividing Line――――

"Hmph~ Hmph hmph hmph~" Having just finished lunch and preparing to clean her statue, Miss Oma suddenly stopped washing the dishes, raised her eyebrows, and looked up at the sky. "This feeling... what happened to Nianzhuo? How could he have such a strong will?" She slowly closed her eyes, and instantly, everything that had happened to Nianzhuo in the Mirror World entered Miss Oma's mind.

After the scene played out like a movie, Miss Oma finally put down her soda and happily continued wiping the dishes.

"Hiccup hiccup hiccup—" (This is the sound of wiping a plate)

"Whoosh whoosh~ What a fool, actually craving power for something like this, as expected of my subject." With her beautiful eyes sparkling, Miss Oma pointed her jade finger and then happily continued wiping the plates.

"Hmm—what kind of room should we reserve for Nianzhuo next?"

It seems our Lady of the Demon Realm had another pleasant day; today is another day without any 25-year-olds (congratulations!).

――――A World of Impure Thoughts――――

"This, this is—" Seeing the golden flames igniting on his right fist, Nianzhuo felt himself being hugged from behind. Two illusory, slender white arms rested on his shoulders, and a black-haired girl whispered in his ear, "As expected of my subject~ So I've come to help you."

Looking at Dan Kuroto, who was neither defending nor dodging, Nencho smiled slightly, "It seems like it might work!"

He then charged towards Dan Kuroto even faster, and just as the distance closed to five steps, suddenly, the world turned black and white.

In this black and white world, only a knight with a black body and a hint of green slowly stepped forward, nodded to Nian Zhuo, and said...

"The power of this time-traveling ability has surpassed the rules. I can't let someone like you continue to grow. So, I'm going to make you a collector's item now!" (That's right, it's our limited-edition Jinchuriki, known as Old Dan, Dan Masamune, Kamen Rider Cronus.)

"Dad! Watch out!!!" Suddenly, a cry of alarm came from Dan Kuroto. Dan Masamune was astonished to find that a fist burning with golden flames was constantly enlarging in his hand.

"Hey—" Then, it hit him perfectly, and Kamen Rider Cronus was sent flying to the very edge of the rooftop by Nencho's punch, with rubble and dirt everywhere.

"I! Call! You! Limited! Edition!" Shouting an ambiguous slogan, Nian Zhuo turned to Tan Lidou, who was still in shock, and was also sent flying by Nian Zhuo.
