He traveled back to four years before the start of the Fairy Tail story, was picked up by Makarov and brought back to the guild, and possessed an infinite enhancement system - ordinary magic can also exert powerful power after dozens of enhancements. Even when facing the powerful Acnologia, he can still cause significant damage even if he does not have dragon-slaying magic.

Many years later, in this magical world, a legend will be spread: in the continent's first guild "Fairy Tail", there was once a group of extremely powerful wizards, and their leader was Sky Infinite...

Lin En woke up in severe pain, and before his eyes was a primeval forest that blocked out the sun.

A car accident? A body shrinking? No, that's not the worst!

At the brink of death, the Clow Cards awakened from the depths of his soul! The power of the rules turned into a natural disaster, and the forest instantly became a purgatory. He was not a magician, but merely the source and fuel of this disaster, and his own uncontrolled power almost drained his soul!

Fortunately, he was rescued by Makarov, the president of Fairy Tail, and Lin En thought he had found his home.

A body drained of magic power, its essence shattered. Even more fatal is the 52 Clow Cards, each possessing its own consciousness, scattered across another world, their whereabouts unknown!

There is no sealed book! There is no sealed key!

Every attempt to get close and reclaim it is a dance with death! The gentle "Tree Card" rejects him, only to protect his fragile body; the absolute silence of the "Silence Card" nearly annihilates his soul; the "Mirror Card" replicates malice, and the "Illusion Card" tears apart reality... Every card is a walking disaster!

"Why are you hiding from me? I need you!"

The plot gears begin to turn... Lucy joins, the ghosts attack, the gate of Hades opens! In this dangerous world full of S-class wizards, how can he protect himself?

The only way to survive is to find the scattered cards and re-establish ties with these "embodiments of rules"!

In his left hand is the Fairy Tail emblem, and in his right hand is the Out of Control World Destruction Card.

Lin En, dragging his broken body, embarked on the thorny road of recovering disaster-level cards in the magical world...

Why does the roar of dragons echo every night at the Fiore border?

A 12-year-old orphan transmigrates and awakens a [card system] while being chased by ghosts.

He drew the [Sky Dragon of Osiris] and unleashed a lightning bolt that shattered the Ghost Headquarters!

Celestial Spirit King was bewildered: "How did Yu-Gi-Oh! cards get mixed up in my Celestial Spirit World?"

The steady old man is trying to survive online, Natsu considers him his older brother and challenges him to a duel, and Makarov urges him to become the guild master.

Watch him use cards to wreak havoc on Fairy Tail, and incidentally burn out Celestial Spirit King's CPU!

Rocky, who traveled to the world of full-time hunters, extracted the S-rank character King Asakura Ye after the first task, and extracted all the abilities of King Asakura Ye.

So a series of tasks began.

Main quest, become a hunter, investigate the Phantom Brigade, clear the island of greed, defeat the ant king, and make Jin Flix the president.

Side quests, kill Hisoka, kill Ilmi, get rid of the Phantom Brigade, assassinate *Tro, and be the enemy of the whole world...

The completion of the task is to reward the abilities or items of the super characters who are all over the world.

However, when faced with the task selection, Rocky smiled, "Children only make choices, adults want all of them, and don't even think about running away from all the task rewards!"

Ronin, transmigrated into the body of a member of the Kurta clan, discovered he didn't possess scarlet eyes, but rather a pair of Sharingan. A pair of Sharingan capable of evolution, capable of granting him ninjutsu. And this was his Special Ability! ...When Uvogin unleashed his Super Destructive Fist, Ronin countered with the same Super Destructive Fist, only this time adding a touch of monstrous strength. When Killua used his Lightning Bolt Technique, Ronin activated his Lightning Release Chakra Mode. When Chrollo painstakingly gathered various abilities to unleash his full power against Ronin, he was sent to the gallows after merely glancing at Ronin's Mangekyou Sharingan, being stabbed repeatedly with a knife by Ronin for 72 hours. When Netero unleashed his Hundred Style Kannon, Ronin piloted his Susanoo to shield him. "Old man, let me..."

Su Ye, who transmigrated to the world of Hunter x Hunter, awakened the Nen ability to materialize the ultimate attacks of anime characters. Netero: "I used to think the Hundred-Style Guanyin was the strongest. But when a Thousand-Armed Buddha hundreds of meters tall appeared before me, I realized what insignificance truly meant." Chimera Ant King: "I was born with the goal of ruling the world, but why was I killed by a mere human with a single punch?" Looking at the Chimera Ant King, whom he had pulverized with a single punch, Su Ye turned to the stunned protagonist group and smiled brightly, "From now on, please call me One-Punch Man!"

[Ding! Please report to the True Central Spiritual Arts Academy immediately to activate the system and begin your legendary journey to becoming a Spirit King!] Hearing the inexplicable voice in his mind and seeing the words appear before his eyes, Qingliu subconsciously looked around. He saw several ninjas wearing green vests and Konoha headbands, and couldn't help but be confused… “System, are you sure you're not mistaken?” [Ding! This system is correct. Please report to the True Central Spiritual Arts Academy as soon as possible!] “???” Good news, he'd transmigrated and had a system. Bad news, the system was from the other side, and the activation conditions were also from the other side. What to do? This is too unreliable! Until one day, just as Qingliu stepped into the gates of the ninja academy, a 'ding' suddenly sounded in his mind… [Ding! Detected that the host has arrived at the True Central Spiritual Arts Academy, becoming…]

Having spent many years in Naruto, he diligently trained, but due to his ordinary talent and lack of system assistance, he could only become an ordinary special Jonin of Konoha. This was probably the pinnacle of Gen Takuno's life. But... Gen Takuno looked at Hiruko, who was attacking Kakashi who had just obtained the Sharingan. It seemed that everything had reached a turning point in his fate. Oni-Garra Technique!

Hiroki, who transmigrated into the body of a nobleman's son-in-law in the Seireitei, initially thought he was destined for a life of ease and comfort in a wealthy family, until his wedding night when he was forced to "receive" over two hundred Uchiha refugees from the Naruto world.

When a misanthropic writer collides with the world of passionate sorcery, the whole world goes crazy!

I find even living troublesome, yet you want me to save the world?

Osamu Dazai, a bandaged beauty who elegantly contemplates death every day, one day fails in his suicide attempt but unexpectedly finds himself transported to the world of Jujutsu Kaisen.

Here—

His "No Longer Human" became the ultimate cheat code!

A cursed spirit? It'll vanish into thin air the moment you touch it!

A technique with no limits? It'll fail the moment you touch it!

Two-Faced Sukuna? The old man Sukuna screamed inside Itadori's body: "Get away from me! This madman is acting strange!!"

Gojo Satoru excitedly invited him, "Come be my teacher! Let's rule the world of jutsu together!"

Yuuji Itadori, his eyes sparkling, exclaimed, "Dazai-san! Teach me how to instantly kill a Super-grade Cursed Spirit!"

Fushiguro Megumi questioned her existence: "...Is this reasonable?"

Kugizaki Nobara went berserk: "Where did this cheater even come from?!"

And Dazai Osamu himself—

Sitting melancholy on the rooftop, gazing at the sunset, he sighed, "Alas... even suicide can't be left in peace."

The most insane invader of the sorcery world in history is about to overturn all the rules!

"Your passionate youth? Boring."

"Your lofty ideals? Ridiculous."

"Since you insist on keeping me alive... then let the world go mad with me."
