[Original world, invincible debt-ridden protagonist, with elements from film, animation, games, and novels]

Good news! Natsume has traveled through time!

Bad news! I was cursed after transmigrating and only have three days to live!

Good news, he awakened the Debt King talent because of the curse.

The bad news is that even if one awakens their talent, it will be difficult to lift the curse within three days.

Good news! The Multiverse Chat Group is here! He can borrow money from group members to solve the curse problem.

The bad news is that the group members aren't stupid; it won't be easy to get help from them.

Tony Stark: "Have you ever seen a magical Iron Man, wearing an Iron Man suit, opening portals to teleport and fight?"

Daigo Masakado: "Is it alright if I put armor on Tiga to prevent him from getting hurt?"

Alicia: "Natsume, quickly turn into a beautiful girl and make me happy."

Kiana Kaslana: "Natsume, come to the moon and cover my shift. I want to go shopping with Mei on Earth."

Dante: "Natsume, to maintain the tradition of the Spartan bloodline, we must be stabbed before the war begins."

Morax: "In general terms, I should be able to smash that island into the sea with one Starburst."

······

Watch as Natsume, with the help of his friends, enjoys himself in his own world while also making up for those regrettable regrets in their world.

When a boy who has traveled to countless places arrives in a world of trees and sea.

He chose to join in, to become a part of the story, to experience it, to experience this "healthy, sunny, and positive" story.

"I don't really like tragedies in my notebook."

"Even the worst author can't write a story using the tears of a beautiful girl."

"Since I'm not satisfied with your story, then I'll have to write it myself."

These are the words this young man spoke to a certain being.

As the story unfolds, only the boy himself knows whether it is the story itself or the characters within it that attract him.

[Legend of the Dragon King Fanfiction]

This is a wonderful era!

Soul Masters have gained even greater potential; battle armor and mechs complement each other, dazzling and magnificent, attracting heroes from all over the world like a swarm of locusts!

Su Qiu transmigrated here and awakened twin martial souls: the Holy Sword and the Holy Spear.

An invasion from the Abyss Dimension? The Holy Spirit Cult's Intention to Destroy the World?

Su Qiu stood in front of the crowd: "What are you all babbling about? Take this first!"

Excalibur, the thirteen bonds released!

“ex...calibur!”

A terrifying beam of light tore everything apart!

......

Soul Beast Race's Revenge.

Su Qiu stood guard alone, looking at Gu Yue and the numerous ferocious beasts behind her.

"Gu Yue, does it have to be this way?"

"I have no choice." Gu Yue's eyes were resolute, unwavering even with the person she loved before her: "It has to be this way!"

"Okay!" Su Qiu replied without hesitation.

"Holy Lance, pull anchor!"

The spear of the end shines!

......

P.S.: Some character designs will be modified to make the original characters more human-like.

The combat power of Soul Masters will be drastically altered and greatly increased, as the combat power depicted in the original work is still a bit too abstract.

There's a legend in the Dou Qi Continent: if you encounter a cliff, don't panic, just jump off, and a great opportunity awaits you. Ye Tian absolutely refused to believe this, until one day, while being chased by a magical beast, he jumped off a cliff in desperation and unexpectedly obtained a tower. At that moment, he believed it… (This book has been modified; feel free to add it to your reading list.)

Having transmigrated to the world of the Starry Sky Railway, Su Bai obtained the Super Dimensional Auction House, which allows people from all over the world to participate in auctions.

Among his auction items were many precious treasures, but the most precious were the fates of his guests.

Black Tower: "Huh?! You're saying the machine head is going to die, killed by the Iron Tomb of the Annihilation Lord?"

Alicia: "Is this our final ending? It really is a romantic story♪"

Tianli: "Me, knock? My men have all rebelled?"

Aizen: "The universe is so vast, yet my eyes are only focused on the Hogyoku. That's far too narrow-minded."

Luo Ji: "Is this a trap set by the Three-Body Problem? Huh, what the heck is this two-dimensional foil?"

Thanos: "Star God? Is he strong? How does he compare to the Infinity Gauntlet? Oh, and you even have Infinity Stones to contend with?"

Batman: "There's a Kryptonite auction? I'll take it..."

Feng Baobao: "The rat talisman I filmed is so much fun... but it's also very expensive!"

Su Bai: "You all say my auction items are ridiculously expensive, but who knows how hard I worked to find them!"

Having transmigrated to the world of Fairy Tail, the protagonist gains the power of words; each letter contains immense strength. B – blaze, F – frozen, P – power… Relying on the abilities granted by words, the protagonist advances on the path to becoming the strongest mage!

Rune, a mediocre wizarding apprentice whose future hangs in the balance, suddenly finds himself transported to another world… “Transportation by horse? Duels by sword?” “So-called noble knights… are nothing more than a bunch of muscular, weak-willed brutes?” A sly smile crept across Rune’s lips. “In the wizarding world, you call me apprentice, and I won’t argue…” “But in this ignorant Middle Ages, what should you call me?”

"Ms. Mengyu, thank you so much for accepting our interview." The host greeted Luo Yu warmly. "It's nothing, you can start asking whatever you want to ask." Luo Yu gestured to the host that they could begin. Host: "Let's begin then. Ms. Mengyu, this fan says your game [Honkai Impact 3] is falsely advertised; it's not a healthy, positive, and uplifting mecha battle game featuring beautiful girls at all." "Fake News!" Luo Yu stood up excitedly. Host: "Ms. Mengyu, please calm down and sit down first." "No one knows Honkai Impact 3 better than me." Luo Yu said, sitting down. Host: "But they say you're engaging in false advertising." Luo Yu: "My game doesn't have any cute girl stickers?" "..." "The game doesn't have any mecha battles?" "..." "Then why do you say my game is false advertising!" "Okay, our program is now over."

Telekinesis, extrasensory perception, hallucinations... An accident during an experiment brought Subject 11 to the world of Fairy Tail. ... "So, am I a psychic or a mage now?" Elivin pondered this pointless question, clutching his head. —————————————————————— No cheat codes, no system, no One Piece or Naruto cameos, just pure Fairy Tail fanfiction. I wanted to write a heartwarming and enjoyable Fairy Tail story. PS: I'm really bad at writing synopses, so check the comments if you're really struggling!
