I'm in Yu-Gi-Oh!, but I'm also in Machine Ascension.

Soon, after confirming that everyone had returned, You Feng immediately opened his system, and instantly, a clear and pleasant familiar system notification sounded:

[Congratulations, host! You have successfully defeated the Three Phantom Demons using the Rank 12 Xyz Machine-Type monster card, Thunderfury - Arceus. Due to the unique nature of the opponent's power, a deck of the same rank will now be unlocked for you.]

[The god of time machines!]

101. Time Machine God: Time Machine Godhood = Mechanical Ascension, no problem!

Soon, the moment he sensed this power, Youfeng immediately noticed the card pack.

The next second, Youfeng immediately noticed that in addition to the remaining mechanical power, the gear-shaped switch on the card pack, which was originally Youfeng's regular reward card pack, had instantly transformed into a faint mechanical clock representing the power of time.

"Hmm... Rather than mechanical power, I remember the power of the [Time Machine God] series comes from the eleven circles of the Kabbalah Tree of Life, right?"

"Furthermore, in the original concept, it was actually closer to the power of time than to machinery..."

After looking at the deck in front of him with slight surprise, and then, as if remembering something, Youfeng glanced at the card pack in his hand with a slightly refreshed expression:

"Hmm?! So, the 'time machine' in 'God of Time Machines' refers to a time machine?!"

"This does fit the original time travel concept—so, isn't this a kind of mechanical ascension?!"

After a slight look of surprise, Youfeng smiled and opened the card pack he had acquired. In an instant, accompanied by a dazzling light, cards appeared in different forms, each representing a different style of the deck.

The most important card in this deck depicts a pale purple body with a green face embedded in its mechanical form. Golden, mysterious symbols adorn its back, and ethereal wing blades unfurl with dazzling divine power.

[Congratulations, host, on successfully obtaining the 10-star Light Attribute Time Machine God Ultimate Monster—Ultimate Time Machine God - Sephiron!]

Ultimate Time Machine God - Sephiron

[Attribute: light]

[Star rating: 10]

[Race: Angel]

[Attack power: 4000]

[Defense: 4000]

...

"very good!"

After happily organizing the rewards from the duel into his card box, Youfeng soon reopened the system page with great interest.

In the menu regarding unlocking more [Special Summon] modes, the progress regarding the [Synchro] power represented by [Scrap II] has also significantly increased since Yuufu's Rank 12 Xyz Monster card [Heavenly Thunder - Azeus] defeated the [Three Phantom Demons] in this epic battle.

[The system has significantly evaluated the excitement of the battle in which the host participated, 'using the Skybreaker to help the Three Phantom Demons achieve mechanical ascension,' greatly accelerating the progress of unlocking the next stage of Synchro Summoning, and this will be synchronized throughout this timeline!]

Soon, accompanied by a flash of light, Yufeng, as a duelist with the bond of card spirits, immediately felt the [Xyz] power in this world, which seemed to have been significantly enhanced.

After stretching his body slightly, Youfeng also entered a good resting mode after taking a bath.

Furthermore, since his card spirit - the spirit behind him - [Sebadorgon] - contributed a lot in this battle, even consuming almost all of its spirit power, Youfeng has allowed it to remain peacefully in its card world for the past few days, without having to respond to its call.

...

Soon after Principal Samejima reported the incident about the "Three Phantom Demons" to Seto Kaiba, the founder of the academy and its president, Seto Kaiba immediately decided to personally take charge of the Duel Academy's renovation work.

With the financial backing of the Haima Group, which is very wealthy, the entire Duel Academy, including the surrounding forests and ecological environment, was well restored in just one week.

Those who had taken a week off from school were immediately notified that they could return to school that afternoon.

"That's definitely in line with the president's style..."

After seeing the photos that Principal Samejima had copied to all the faculty and staff about the construction of the new Duel Academy, and looking at the even more luxurious buildings on his phone compared to before, Yuuka shook his head with a slight sigh.

then--

After receiving this email, Youfeng quickly scrolled through his mailing list. After skipping over the emails from JIO Nokia—Katsuya Jonouchi—that he communicated with daily, a mysterious email address that had never appeared before immediately came into Youfeng's view.

【International Illusion Society】—and the sender's name is "Bekas".

"Pegasus, known as the 'Father of Card Games'? It seems—he's finally been targeted!"

With a slight sigh, Youfeng immediately opened the email. Somewhat unexpectedly, the email turned out to be an "invitation email." In it, Pegasus, who held the rights to develop the cards, invited Youfeng in a very calm tone to join the development of a "completely exciting new summoning mode."

"Hmm...it seems...the system is quite efficient..."

After a slight surprise, Youfeng immediately archived the email without giving an immediate response.

...

The special date of the completion of this new Duel Academy also marked the end of the first semester, after which the Duel Academy's tests and examinations were immediately conducted.

Although this test was within Youfeng's authority, it was actually entirely led by Professor Chronos. According to the Duel Academy's management, students who passed the test smoothly had the opportunity to advance, while those who performed averagely would remain in their original dormitories. However, if they performed poorly, they would be expelled from the Duel Academy.

This test, like an entrance exam, consists of two parts: a written test and a practical test.

However, as Yuuki's dueling philosophy gradually underwent innovation in this era, the focus was entirely on the practical dueling stage, which made classic "poor starters" like Jaden Yuuki cry out "I'm saved!"

As agreed beforehand, the duel was immediately between Professor Chronos and Jaden Yuki. The "Mushroom Head" teacher, who vowed to restore the power of the Ancient Machine Titan, was defeated once again.

This time, Jaden Yuki directly used the [E-HERO Flame Wingman] and, with the added power of the [Skyscraper], demonstrated the strength of the "Three Thousand Assassins"!

...

"Won. It was an interesting duel!"

As Yuki Jaden, the "jellyfish-headed" boy who had just entered the duel arena, excitedly raised his fist, Yufeng immediately noticed that when Yuki Jaden was summoning "E-HERO Flame Wingman," he opened his "Extra Deck" and found several brand-new "HERO" series Fusion Monster cards.

Instantly, he was slightly surprised and said:

"Hmm... Judai, you actually got the [M-HERO] deck already?"

Soon, amidst Yuuki's surprised voice, Judai Yuuki immediately smiled and nodded, then crossed his arms, still looking somewhat "painful," and said:

"Yes... because of this, I've been opening a lot of card packs, and I've completely maxed out my allowance for the past few months..."

Even so, despite a slight sense of disappointment, Jaden Yuki's expression still held an unparalleled anticipation for the new deck.

Seeing the enthusiastic Jaden Yuki, Yuuka smiled slightly and patted the still sunny boy in his 1.0 version on the shoulder:

"However... Judai, do you know what the true core strength of your [M-HERO] deck is?"

...

Soon, when faced with Yuuki's question, Jaden Yuuki was momentarily stunned and fell into deep thought:

"...It should be, acidic water...?"

After hesitantly guessing, Jaden Yuki spread out his palms with a helpless expression:

"Is the power source of this deck [Kamen Rider]? As a long-time fan... I really have a hard time judging the strength of the heroes!"

As Jaden Yuki sighed, Yuuka nodded thoughtfully, then immediately chuckled and teased:

"Then, consider this one of your homework assignments, Jaden—find the core monster card in the [M-HERO] deck known as 'Friend Hero' and add it to your deck..."

After taking out his phone and confirming the time, Youfeng nodded slightly.

"Hmm... the deadline is on the day of the school festival, right..."

"Okay~ then—"

Just as Jaden Yuki was about to give a crisp and enthusiastic reply, he froze for a moment, his lips twitched slightly, and then he protested loudly with a contorted expression:

"But that means there are only two days left!"

...

Then, amidst the extremely "tragic" cries of Yuki Judai, I watched Yuuki's dashing figure disappear into the distance.

Asuka Tenjouin immediately walked over with a smile, looking at Ryo Marufuji, who was calm and even somewhat "envious" of Jaden Yuki receiving guidance, and Jun Manjoume, who looked "gloating".

The girl's bright eyes darted back and forth between the group of people:

"Speaking of -"

"Have you all thought it through? Do you want to participate in the [COSPLAY Duel] hosted by Judai's [Osiris-Red] dormitory during the school festival?"

"—Didn't Senior Yuuka say 'This is pretty good' after seeing the plans from various schools for the school festival? Knowing his personality, he'll definitely participate in person, right?"

Along with the girl's laughter, the blue-eyed, gray-pupiled boy in the blue Obelisk-Blue academy uniform immediately nodded:

"...I'll be participating with Teacher Yufeng...but...I'm not good at dressing up—but..."

Soon, Ryo Marufuji also immediately set his sights on Judai Yuki:

"Although I will graduate from the Duel Academy after this semester and embark on the path of a professional duelist, I still have many questions about dueling that I need to answer..."

"And during the school festival, Jaden Yuki, I hope that, as we agreed, you will send me off with a magnificent duel."

Upon hearing Ryo Marufuji's deep voice, Jaden Yuki immediately nodded excitedly.

"...To be able to fight against a strong opponent like Marufuji-senpai is my long-cherished wish as a duelist!"

...

Soon, following their agreement, Jun Manjou shrugged and looked at the girl, Asuka Tenjouin, with a smile:

"In that case, as the next champion of the Duel Academy, I will naturally witness the passing of the torch from the old champion to the new champion in the Duel Academy!"

Amidst the black-haired boy's confident and excited voice, Tenjouin Asuka gazed wistfully in the direction Yuuka had gone:

"I wonder... what cosplay outfit Senior Yuuka will wear for her appearance..."

Under the girl's slightly wistful gaze, behind her, Tenjouin Fubuki, who had been "rescued" from the [Three Phantom Demons] incident but was forced to repeat a grade due to her unexplained disappearance, immediately shook her head as she looked at her younger sister's "girlishly thoughtful" expression.

"...Although we haven't spent much time together, even if Master Yuuka, a senior duelist, were to participate... he probably wouldn't be doing cosplay..."

As Tenjouin Fubuki uttered a soft sigh, everyone nodded in agreement.

...

But the next day—

The cosplay duel, which became exceptionally lively and extravagant due to Youfeng's participation, was originally a staple of the Osiris-Red event and was elevated to a school-wide activity.

Even under Wan Zhangmu's intervention, the red carpet was replaced with blue, representing "Obelisk Blue".

After careful preparation, the group, who had completed their final cosplay outfits, quickly gathered and headed towards the venue.

"?! This is... Manjoume-kun, yours is the [XYZ-Shinryu Cannon]! I must say, the accuracy of the reproduction is exceptionally high!"
