What changes would an immortal mutant, who doesn't exist in the comics, bring to Marvel? For example, Deadpool wouldn't be disfigured. For example, Iron Man would open a hot pot restaurant. For example... there wouldn't be any cheat codes. The timeline and plot are based on this article.

Synopsis: "My name is Chen Zhan. I've become a test subject for the Foundation and am now caught in an endless experiment." (173 "Statue - The First Work," 682 "The Immortal Lizard," 999 "The Itchy Monster," 131 "Eye Beans," 939 "Thousands...")

I woke up to find myself in a world where Pokémon and reality have merged. Along with me came a handheld console. Everything I acquired on the console could be extracted into reality. Should I just start grinding for shiny Pokémon? Can I catch Ralts on Route 104? Should I just buy a house and keep grinding until I get a shiny one? No money for training Pokémon? With five Zigzagoon Pokémon possessing the Pickup Ability, I'll become a millionaire by scavenging! Then, I'll put the Thief move on cooldown, start jailed at the entrance of the Spiral Tower, grinding for shiny Dratini while stealing Dragon-type security tokens. Wait, I remember there's a Master Ball in Team Aqua's base... Years later, at the World Pokémon Championships. The champions: Where did his shiny Rayquaza come from?

Where does my soul reside? A sorrow from a thousand years ago, destiny calls for the glory of the sword. The Western gods destroyed everything, leaving only their own self-proclaimed tragic beauty. But some still remember that man and his sword; who can withstand the sword's edge that slays the world? "Master, I'm sorry. I'm willing to redeem my original sin with my entire life. Please let me stay," the angel murmured, yet dared not look him in the eye. "Master, you've come to take me away, haven't you?" The little devil, a smile still lingering on his lips, looked at him. "Brother? What's that? Tears? And what is this?" The sister, who had stopped and forgotten everything, stared at him blankly. "Uncle, are you really willing to stand before me, forever and ever?" The fallen princess of the cat clan gazed at him sorrowfully. In the name of the sword, little girl, come to my bowl!

The protagonist, Lu Bai, was playing Minecraft when he drank some water and choked to death. After waking up, he found himself in Minecraft and joined the Undead Legion.

him: Practical skills, mild temperament, a good member.

null: ...His plants are very quiet. (In contrast to a noisy teammate)

Entity 303: Little White is super funny! He's my best prank partner! ...Although he always gets caught by Boss Him. (︶︿︶)

Dreadlord: His calming herbs worked very well and helped stabilize many of my potions.

Death Knight: His bone broth... is incredibly delicious!

The main character will change later...

[Gender swap + yuri + everyday life + female devil]

My name is Shang Qingxun.

If you ignore my appearance

Just like my name,

Pure and innocent, seeking the ordinary.

But why? I'm a guy, why would I have a cross-dressing system?!

In the dead of night, a blonde girl was slapping Shang Qingxun across the face repeatedly.

"Master, wake up!!!"

From that moment on, Shang Qingxun's life was no longer ordinary.

His/Her story begins...

"I don't want to become a girl!!!"

Groudon soars gracefully through the clouds, its form comparable to Ho-Oh;

Dialga and Palkia snuggled close together, their time and space boundaries blurred and harmonious.

Yveltal, the God of Destruction, unleashed a Deathwing strike, instantly reviving the withered forest.

…………

Water Wutong stared in disbelief, pointing at the sky: "It can't fly... how did it get up there?!"

The crimson sun's worldview shattered, and it murmured to itself, "Time and space... why are they no longer in opposition?!"

Vladali broke down on the spot: "What happened to the destruction and rebirth?! My Brave New World!"

Meanwhile, in the underground laboratory of Kanaz City, the white-haired, blue-eyed boy, Zhu Xi, pushed up his analytical glasses and, facing the League Champion and various villains who came to his door with complicated expressions, spread his hands innocently: "Why are you all looking at me like that? I'm just an ordinary inventor who buries himself in making some small inventions."

Everyone's gaze passed over him, landing on the oddly designed devices operating at the back of the laboratory: [Groudon Leyline Energy Guidance and Anti-Gravity Hovering Wing], [Dialga and Palkia Spacetime Resonance Coordinator], [Life/Destruction Energy Reverse Conversion Device (Yveltal Special Edition)], and the [Giratina Temper Soothing and Reversal World Ecosystem Maintenance System (Under Testing)] prominently marked on the design drawings next to it...

After a deathly silence, someone let out a long and complex sigh.

Something seems off about this Pokémon world, yet it also seems... to be moving towards some unprecedented harmony and "reason"?

No one would label someone as a genius who has played for four years and five thousand hours but whose rank is only A to A+. Lin Yu, an ordinary college student, thought he might never have a chance to compete in the professional CS scene.

But an accident changed everything. He was reborn in 2021, on the day of the Stockholm final, and also awakened a system.

He learned from the system that as long as he worked hard, he could become stronger, and it also gave him 24 hours more practice time than ordinary people.

This made Lin Yu realize that he might have the potential to become a professional player.

If some people can become number one in 10,000 hours, then he can use 20,000 or 30,000 hours, and one day, through his own efforts, he will be able to stand at the top of the world.
