Ye Lan, who is obsessed with Grass-type Pokémon, wakes up to find the world completely changed!

Ye Lan was dumbfounded as she looked at all the news about Pokémon on her phone.

"Am I crazy? No, I'm not crazy! This time, I'm determined to lead the Grass-type to the top!"

"Ding! Congratulations, host, you have awakened the Grass-type Elite Four Training System!"

"That year, I saw the students of Class B slumped in their chairs, sobbing uncontrollably. That scene is unforgettable. At that moment, I thought, if I could become the class president of Class B, I would lead Class B to victory!" "So, Ichinose, let me be the class president of Class B." "No, Uesugi-kun, you're too radical." "Ichinose, you'll regret this!" "Uesugi, I am the class president of Class B." *Slap!*... "Hmph, naive Ichinose, do you think I can't do anything if you don't agree? Shibata, notify Kanzaki to prepare to close the net!" "Uh, um, Uesugi—" "Shut up, Shibata, this time we must act quickly. Before Ichinose can react, expel them from school. I want to see who can stop me this time." After a while, "The wind on the rooftop is so strong..." "Uesugi, come down quickly, I will never reveal your plans to Ichinose again." "You write it down!!"

[No romantic pairing + a comprehensive overview of the universe + no main character + a shocking spectacle across all realms + a chaotic hodgepodge]

The celestial canopy descended upon all realms, causing all the heavens to tremble!

Warhammer 40,000: The Imperium of Man is dying in the Galactic Blood War, the Emperor sits on the Golden Throne in vain, Primarchs betray him one after another, and the Chaos God whispers! Loyalty and betrayal weave a tragic epic!

Lord of Mysteries: In the mist-shrouded steam age, mortals pilgrimage to godhood by consuming potions! The struggle for the order of things twists madly, the Great Old Ones awaken silently, and the countdown to the apocalypse has begun!

Mysterious Resurgence: Ghosts and monsters have resurfaced globally, and vengeful spirits have brought a new rule of killing! Mortals fight ghosts with ghosts, harnessing evil spirits to seek a glimmer of hope! Who are the ghosts? Who are the humans? Despair spreads across the globe!

The audience across countless worlds went completely mad: "A world even more sanity-destroying than Warhammer has appeared!" "The potion pathway is more terrifying than Chaos Corruption!" "The Ghostly Rule System is unsolvable? Can the Bolt Gun solve it?" "These worlds are more insane and desperate than the last!"

When the Astartes of Warhammer encounter the mysterious Sequence Path... When the Emperor of the Golden Throne gazes upon the mysteriously resurrected vengeful spirit... Who will be the darkest and most despairing world in the universe?

Bad News: Waking up in a different world. Good News: It's Prince of Tennis. Bad News: The protagonist was a tennis novice before the time travel. Good News: He met Jujiro, a demon who hadn't yet joined the U17 team. Furthermore, he awakened the mysterious Six Paths Dimension, where opponents he'd previously played against can appear in his dreams. Furthermore, each door in the Six Paths Dimension grants him a special ability bonus. After witnessing the rise of demons and facing off against the young "First Army," the protagonist joins Seigaku, completely overhauls the tennis club, and leads it to the national championship. He lays low in the U17 team, hones his skills in the expedition team, and rises to fame in the World Cup. Ultimately, he becomes the tennis king everyone dreams of! The synopsis is too much to read, but after the transition period, the excitement begins with the Jr. Tournament section. (Already available: the excellent Prince of Tennis fanfiction "In Prince of Tennis, I Have a Tennis Mini-Game...")

He traveled through time and space and became Namikaze Raimon, the elder brother of Minato Namikaze. He was resurrected by Orochimaru during the Chunin Exam. The man who made the ninja world's anus tighten has returned to the eyes of the world!

Ohnoki: This guy kicked my kidney!

Edo Tensei Tobirama: I withstood a blow from the Steel Gate Ripper! Don’t you think I’m awesome?

Namikaze Kaminarimon: It's normal to feel dizzy and it's normal to have a sore butt. Take a deep breath and relax!

Namikaze Raimon's ninjutsu is a bit unorthodox. He makes the wind and thunder attribute Rasengan into the shape of a drill, and specifically hits the anus. He also knows Flying Thunder God, which is impossible to block or escape.

The earth escape technique can cause kidney stones in your body, and even urine can kill you!

After traveling to the pirate world, you still think about just lying down and living your life. Can you have some ambition?!

Adolf D. York, a time traveler without a system, obtained the Superman Happy Fruit by making a wish.

"I have only two biggest wishes in this life!"

"First, wake up and take power over the world!"

"The second one, drunkenly lying on the lap of a beauty!"

“Whether I can do it or not is not known yet, but I will definitely do it!”

"As for dying, I deserve it. I don't have the ability to do that!"

"And the first step to realize my dream! I choose to join the Rocks Pirates to learn advanced experience!"

………………

Many years later.

Adolf D. York sits on the high throne of the Holy Land of Mary Geoise.

Standing around him were countless beauties in maid outfits, including Im, Nami, Robin, and the Empress, and in front of him were reporters from all over the world.

Facing the camera, he said: "Everyone must have dreams. What if they really come true? I am the best example!"

Overnight, five unremarkable black buildings in downtown Tokyo underwent a complete transformation, with their interiors and personnel suddenly replaced. After realizing the Port Mafia had been transported to a world without supernatural abilities, Leader Mori solemnly declared at a meeting, "We must try our best to conceal the existence of supernatural abilities." The group exchanged hesitant glances and nodded. Just as the dejected doctor was about to be...

Makino, who was terminally ill, accidentally carried the Soul-Eating Tree seeds with him through the Devouring World and took over the body of a cosmic-level warrior who had just experienced a life-and-death battle with a giant axe.

After killing the enemy, the Soul-Eating Tree can absorb the enemy's soul and show all the enemy's memories during his lifetime, including his understanding of martial arts, domain, and laws, to Makino.

After completing a thousand life-and-death battles, Muye chose to enter the battlefield outside the domain, where countless enemies were waiting for him to kill - or be killed...

The non-Earth chapter begins, the timeline is before the start of the original work, and the realm starts from the cosmic level.
