Roger traveled to the world of Harry Potter.

The game started on hellish difficulty; he became the apprentice of an old, powerful, and extremely temperamental dark wizard. Just as he was cautiously serving this unpredictable mentor, he unexpectedly discovered that the bio-computer he had developed in his previous life had also transmigrated with him!

From then on, Roger's magical training began with the three Unforgivable Curses! "Analysis of the Imperius Curse complete." "Begin observing Professor Quirrell."

Years later, when the Daily Prophet was preparing to write a legendary feature on Mr. Roger Lewis, prominent figures in the wizarding world spoke out:

Professor McGonagall (with a serious expression of amazement): "Without a doubt, Mr. Lewis is an unprecedentedly outstanding graduate in the history of Hogwarts." Dumbledore (his wisdom gleaming behind his half-moon spectacles): "I must admit that no one understood the nature of magic better than Roger. Not even the four founders of Hogwarts." Voldemort (in a complex tone): "It is well known that I made indelible contributions to Roger's magical research..."

Rita Skeeter (writing furiously with her quill pen, her eyes gleaming with gossip): "Mr. Riddle, was it the summer before Mr. Lewis enrolled?"

Voldemort (lost in memories): "Sigh...that summer, they invited me to participate in the experiment, though the method was crude...If they had said it was to develop an elixir of immortality, I could have provided tremendous assistance! I wouldn't have needed to go through the trouble of finding the Philosopher's Stone...I still deeply regret missing this opportunity to return sooner!"

Six years after graduation, Xia Yan returned to the Ninja Academy, but this time as a sealing technique teacher.

He teaches rune ninjutsu, uses card games as teaching aids, runs taverns, makes movies, and builds chakra networks...

What kind of changes will the ninja world undergo when sealing techniques are combined with modern imagination?

PS: This is a breakup of the main pairings; only Kushina is the female lead. Please do not contact me if you are not interested.

Having been unexpectedly transported to another world, Ye Yu initially thought he could enjoy his new life peacefully, without attachment to worldly affairs or the pursuit of immortality, only desiring a prosperous world and a peaceful existence. However, the world he encountered turned out to be Sword Art Online, and he happened to be caught in the open beta period of a game where thousands gathered—a death game. His new life began with imminent death, inescapable and unavoidable. Thus, his only recourse was to draw his sword in anger, carving out a vast starry sky where he could roam freely and roam the world. Human strength was insufficient, but fortunately, the system might be late, but it would never be absent. Bound to the God-level Choice System, Ye Yu grew increasingly powerful. After clearing the game, he returned to his daily life, expecting it to be just swordplay, but… Soubu High School, Otonokizaka… what the hell?! PS: A crossover anime slice-of-life Sword Art Online + Oregairu + Love Live! + ? ? ? ? (To be determined) This book has a relatively slow pace; those who prefer fast-paced stories should not read it.

Lin Feng, a typical office worker, wakes up to find himself a "low-achieving student" at a magic high school? His theoretical knowledge is terrible, and his practical skills are lacking.

However, he unexpectedly awakened the Eye of [Analysis and Reconstruction of All Laws]—all magic in the world appears as transparent code to him! Optimize CAD? See through flaws? Analyze the essence?

Lin Feng's journey begins with a clash with the rampaging "Ice Queen" Miyuki Shiba! Faced with the raging magic that even the "Demon King" Tatsuya had to carefully suppress, Lin Feng inexplicably reached out a finger and gently touched it... and the raging magic instantly became as docile as a lamb?!

Miyuki was stunned: How could this underachiever give her a sense of security that rivaled that of her brother? Tatsuya was on guard: Was this man a threat or a savior?

Witness how Lin Feng, seemingly an "underachiever," outwits a formidable foe and becomes a legend in the Nine Schools Tournament! He strikes at the heart of Shen Xue's shackles.

She is favored by student council member Mayumi Nanakusa, challenged by the tsundere Erika Chiba, and admired by the gentle junior Honoka Mitsui.

During the Yokohama Incident, he protected the women, nullifying missiles with his Eye of Law! On the international stage, he deciphered the secret techniques of various countries, gaining worldwide fame! On the night of the four-leaf clover, he faced the Queen of the Night, reconstructing a secret technique that shocked the entire audience!

As the world is in turmoil and the ultimate crisis arrives, Lin Feng will use the "laws" as his sword to protect his loved ones and rebuild order!

His legendary comeback story begins here! Experience thrilling battles, strategic clashes, sweet romance, and heartwarming everyday moments.

Transmigrated Cang, possessing a flint-wielding left eye that awakens a magical world, uncovers a cosmic truth with his cousin, Shenxue: Earth is actually a prison for alien gravediggers, and Shenxue's family bloodline is a container for a spiritual virus. The two break through seven cycles of reincarnation, discovering that the world is actually a fairytale manuscript from a higher realm. Ultimately, they tear apart the shackles of narrative, wielding the silver-haired flint-wielding pen to rewrite the laws, transforming bronze doors into bookshelves, and the gravediggers into footnotes to the fairytale.

In the world of "The Irregular at Magic High School," I was bound to a villain simulator.

[Mission 1: Publicly humiliate Shiba Tatsuya, instilling murderous intent in Shiba Miyuki towards you. Reward: S-rank magic - Gravity Collapse!]

[Mission Two: Eliminate Mayumi Nanakusa during the Nine Schools Battle. Reward: God-tier CAD - Eternal Heart!]

As a result, I became a scoundrel, a villain, and a demon in everyone's eyes!

But they didn't know that when Yokohama was engulfed in flames, I transformed into "Nameless," suppressing the entire scene with a single Gravity Collapse attack. When the Great Asia Alliance invaded, I transformed into "Phantom," protecting all of Japan with my Eternal Heart.

The female protagonists, while gritting their teeth and vowing to kill me, are also searching the world for their savior, hoping to repay him with their bodies.

Until that day, my vest accidentally fell off.

Looking at the petrified female protagonists, I shrugged: "Surprised? That's right, the Demon King you hate the most and the hero you love the most are both me."

[No female protagonist] It’s not that I don’t want to write, it’s that I can’t

It took Samael 11 years of traveling back and forth to realize that he had come to the world of Harry Potter and had become a wandering descendant of the Gaunt family.

What kind of sparks will be produced when Parseltongue meets Anaconda?

What effect will occur when werewolf venom is combined with the blood curse?

What changes will happen when Orochimaru meets the Green Snake with Three Flowers?

Samael Gaunt, a wizard seeking fame and power.

Harry Potter: He was my best friend.

Dumbledore: He is a true Slytherin.

Snape: He might be the third Dark Lord.

Hagrid: We have the same hobbies.

Travel through the world of Harry Potter and obtain the [Positive Energy Explosion Attribute System].

As long as you do positive things, the relevant people may drop attributes.

"I picked up 1000 Occlumency experience points, and my Occlumency skill level reached max. I got the achievement: Spell Mastery!"

"I picked up 500 points of Potions experience, and my Potions skill level was upgraded to level 5. I got the achievement: Potions Master!"

"I picked up 1000 points of physical experience, and my physical fitness increased to level 7. I got the achievement: Tear a dragon apart with my bare hands!"

...

Snape: "Are you an expert in potions? You should be the one to take the potions class from now on!"

Dumbledore: "You can master all spells at once, and you are so positive! You are the hope of the wizarding world!"

Voldemort: "We are all wizards. What do you mean by tearing the earth apart with your bare hands? Also, how come you are more proficient in dark magic than I am?"

Looking at the various black magic spells at the maximum level on his panel, Lynch was speechless.

Do positive things, why is the attribute explosion rate of black magic so high?

He looked at the admiring eyes of the people in the magic world:

"Although I'm very proficient in the dark arts, that doesn't prevent me from being the most positive wizard in the world. No one should object, right?"

Ye Shu, a good-for-nothing otaku, traveled through time and space, finding himself in a mediocre modern city. With no supernatural powers, let alone superheroes, he expected to live an ordinary life. However, at the age of eleven, his life took a surprising turn. "Attention, freshmen! No student is allowed to enter the Dark Forest. This is for you, Ravenclaw Ye Shu! As a senior, you must not do anything that might lead the freshmen astray!" Dumbledore declared at the freshman welcome dinner. "A cauldron is for brewing potions, not for cooking. Ravenclaw students, especially, do not imitate your senior, Ye Shu!" Snape sternly warned the freshmen during Potions class. "Broomsticks are for riding, not for standing on them and yelling about flying. Do not imitate Ye Shu's absurd behavior!" Madam Hooch declared, broomstick in hand, addressing the freshmen. "What on earth did this senior Ye Shu do that angered everyone?" The freshmen looked at each other in bewilderment.
