Maurice, reborn, wanted a peaceful life, but a letter from Hogwarts disrupted his plans. Along with it appeared a book detailing various forms of necromancy. Becoming a necromancer? Perhaps that wasn't so bad. Bones as servants, ghosts as companions, the whispers of the dead murmuring in his ear. "I'm just an ordinary wizard who loves research," Maurice said with a gentle smile to his trembling classmates. Until one day, he suddenly woke up in front of the mirror—wait, could he be a psychopath who deals with corpses all day?

What is calamity? Disaster and suffering? Unfortunate circumstances? Looking back suddenly, I find myself in the strange pirate world of [ONE PIECE]! Transmigrated? But I have a cheat code! One equipment slot at the start? This is the white town of Flevans! It is currently facing a massacre that will destroy the entire nation! ...Those who kill—will be killed. This is the story of a boy suffering from platinum lead poisoning, who walks out of this white city and into the world. Want to be a pirate? Then (cold laugh), let's climb to the top step by step! PS: Special skills, Devil Fruits... PS:—

Si Jinkun, who traveled to the Demon Slayer world, shouted at the beginning: I don’t want to be a human being anymore!

He went completely crazy after arriving in the world of Demon Slayer

That shadow that has lingered for a thousand years—Muzan Kibutsuji! That pitiful creature who cowers in fear because of the curse, that false king who vainly seeks immortality!

All his struggles and blood ghost arts became futile jokes in front of Si Jinkun's ultimate body that combined the curse of the stone ghost face and the essence of countless ghosts!

He treats Wuzan as a high-end bun

It also forced the demons and the Demon Slayer Corps to join forces for the only time in a hundred years.

Many years later, Si Jinkun, who had already become a JO-level creature, looked at the world he had ruined and fell into deep thought.

In the world of True Spirits, where bloodlines cultivate immortality, True Spirits reign supreme. The first-rank True Spirit family, the Golden Crow Emperor, sees their Golden Crow bloodline transform into the sun, illuminating the ten directions. The second-rank True Spirit family, the Taiyin Jade Rabbit Jade family, sees their Jade Rabbit bloodline transform into the moon, showering down its moonlight and blessing the people. The bloodlines of the Azure Dragon, White Tiger, Vermillion Bird, and Black Tortoise transform into the four constellations, guarding the four directions. The bloodlines of the third to ninth-rank True Spirit families transform into the stars, suppressing them from above. This is a world controlled by numerous True Spirit families. Kong Wenxuan, born into a family with Peacock bloodline, carries the inheritance of the "Five-Colored Divine Light." His first step is to elevate his family's Peacock bloodline to the position of True Spirit, transforming it into stars embedded in the sky.

An Yi, who was using Li Bai to steal the enemy's red buff, was startled by a looter hiding in the bushes and unexpectedly transmigrated into the newly released global holographic game, Sword Art Online. He accidentally activated the King of Glory system, learned the Azure Lotus Sword Immortal skill at the start, and had a chance to obtain points by defeating monsters. These points could be used to purchase various gift packs provided by the system.

Yi An: There's no time to mourn King of Glory, now it's time for the Azure Lotus Sword Immortal himself to appear, the most handsome man with swords and blades, the ceiling of sword and blade combat power!

Kirito: His sword is too fast. I have never seen anyone wield a sword so fast. He is a legend.

Asuna: I once regretted letting Kirito play with him.

Sinon: I feel so safe with him!

Looking at the system in front of him, Tiandao wanted to shout, "Damn idiot! System, do you even recognize me as an Uchiha?"

However, looking at the rewards listed by the system: [Sharingan, Hashirama Cells, Sage Mode, Yin-Yang Release.]

"Since that's the case, then let me see your limits. System, activate it!"

"No, bro, am I being cunning? My Flying Thunder God Slash has a pre-swing, so it requires some skill. Hard Vortex Water Blade has low damage...

By the way, my Four Red Yang Formation with the Multiplication Detonating Talisman has high prerequisites and is not practical."

"What? Sharingan? You can see everything? Can you react to Flying Thunder God? Bro!!"

"You said your Rinnegan absorbs all ninjutsu? Who told you I was using ninjutsu?"

The white-haired, spiky-haired man with red eyes stood on the Hokage Rock, overlooking everything in Konoha.

"Third-generation master, you, the Fourth-generation master, the Second-generation master, and the First-generation master have all taken the wrong path. How much money can you earn fighting as a ninja?"

Not black Sarutobi + no system micro-cheat + Naruto stalk + black belly

Huang Quan transmigrated to the primordial world, becoming the true spirit of the River of Oblivion and awakening the Treasure Refining and Divine Fusion System. Not only could he refine spiritual treasures and fruits much faster, but he could also fuse any two spiritual treasures or divine abilities to obtain even stronger ones. Soul-Capturing Banner + ... Profound Yin Ghost Banner = Human Emperor Banner! Reincarnation Purple Lotus + ... Merit Golden Lotus = Chaos Azure Lotus! Northern Profound Origin Water Control Banner + ... However, at that time, the underground passage had not yet been completed, and the Netherworld was incomplete, preventing the River of Oblivion from taking form. Left with no other choice, Huang Quan could only create an avatar to find a way to repair the Netherworld and perfect his own foundation, hoping for a chance to take form.
