In the year 1462 of the Sea Calendar, 13-year-old Yudian enrolled in the same school as Garp and Sengoku, only to be utterly defeated in the Marine Headquarters training camp. In this world of talent and Devil Fruits, Yudian could only rely on hard work and the system. 'Ding! Host needs to run 100,000 laps around Marine Headquarters to reach the maximum level of Six Styles - Shave!' 'Ding! Host needs to poke stones 1 million times with his fingers to reach the maximum level of Six Styles - Finger Pistol!'... 'Ding! Host needs to smash 10,000 mountains with Armament Haki fists to reach the maximum level of Armament Haki!' 'Ding! Host...' Listening to the system's repeated prompts and those ridiculous training tasks, Yudian felt immense pressure! However, after defeating Whitebeard with a single punch, the force of his punch blowing away Shiki, and his power intimidating Roger, he realized that his previous hellish training was indeed worthwhile.

[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.

Lucci: From the moment Luffy became his younger brother, it was a sign that he would always protect him, and he would watch him become the Pirate King! Ace and Sabo: This guy is even more of a brother complex than us. Lucci's promise to always protect Luffy isn't just "ASL," it's "ASLL," right? They're not just three brothers, they're four! How will this story unfold?

Don't talk to me about bloodline limits; that's just an outdated chapter in my theory.

Transmigrating into Naruto, Uesugi Tetsu's "AI brain" can analyze everything.

While others train in the Great Fireball Technique, he optimizes the underlying chakra formula, doubling its power. While others rely on the Sharingan, he creates an "artificial spiritual root" system, enabling everyone to achieve greatness.

From the Three Bodies Technique to Sage Mode, from the Sharingan to the Rinnegan, all the mythical ninjutsu and bloodline limits are nothing more than lines of code that can be rewritten and surpassed in his eyes.

He refused the position of Hokage and founded the transnational "Spiritual Power Academy." When the Otsutsuki clan descended, he was already the founder who led the entire planet's civilization to fight against them.

These days, without a system, even your life isn't guaranteed when you transmigrate. Fortunately, while there's no system, there's a cheat code… Ye Yu has transmigrated to countless worlds simultaneously, able to share and feedback his power with others. In the Naruto world, he faced Six Paths Madara head-on, with five thunder dragons roaring to the sky behind him. In the One Piece world, he escaped from Impel Down and shocked the world at Marineford. In the Bleach world, he ascended the throne of Heaven before Aizen. In the A Certain Magical Index world, he's a legend in Academy City, hailed as the man most likely to become a Level 6 esper. In the Detective Conan world, he possesses special abilities and is a guest of honor for many conglomerates. In other worlds, he's also a pinnacle of existence… In all these worlds, Ye Yu humbly stated that without the “strong support” of his colleagues, he would have been in a difficult situation. What…

When Ryan opened his eyes, he found himself transported to the perilous world of One Piece with a useless system.

Here, pirates roam freely and danger lurks everywhere. The strong can slaughter islands and destroy countries, while nobles are domineering and arbitrarily reduce people to slavery.

What?

You're saying I'm a Celestial Dragon?

Ryan said, "Then I'll lie down."

Father, a ninja's capacity truly has its limits. In my short ninja career, I've observed that the harder a ninja trains and the more desperately they fight, the more likely they are to die a pitiful, short-lived death. You must become someone who transcends the ninja realm! What? Son, what are you saying? I… I'm not going to be a ninja anymore, Father!

After awakening his past life memories, Ryan suddenly realized that he had traveled to Fairy Tail. Along with it, his own magic [Dragon Root] awakened, which could summon things with dragon attributes in other worlds.

With Blue-Eyes White Dragon under his feet, War Greymon, and Storm Dragon always by his side, and the dragon circling behind him, Ryan thought so, but...

Magazine reporter: Mr. Ryan, what do you think of your nickname of the Cute Dragon Summoner?

Ryan: I repeat it again! It's the Fierce Dragon! Not Cute Dragon!

Ryan really couldn't understand why he summoned cute dragons. And this reputation seemed to have spread to other worlds.
