Terraria][Half-Invincible] The protagonist Lin Yu inexplicably appeared in the world of Chainsaw Man. Denci: What potion did you just give me to drink? Why did I become a woman? Hayakawa Aki: Lin Yu! Can I only use it after drinking this? Lin Yu: Of course.

Chiya Otonashi travels to the demon-ridden world of Chainsaw Man and acquires the Mangekyō Sharingan's Kamui, and even double Kamui! [After writing Chainsaw Man, I'll probably write about a variety show. The anime I'll be traveling through are tentatively: Attack on Titan, Black Bullet, Akame ga Slash, Tokyo Ghoul... (in no particular order)]

Chen Xuan has been in the cultivation world for fifteen years. Although he's just an odd-job worker for a cultivation family, he's successfully embarked on the path of immortality, with a promising future ahead. However, while diligently cultivating, an old friend informed him he's fated to die in three years!

At this crucial moment, he awakened the Simulator System. Each simulation allows him to choose different talent traits:

Sword Dao Genius: You possess extremely high comprehension of the Sword Dao; you learn it instantly.

Spirit Medium: You can hear the inner thoughts of demonic beasts.

Financial Tycoon: You're highly sensitive to economics, transforming into a ruthless capitalist, madly accumulating wealth.

Plagued by Bad Luck: Your entire life is unlucky, and those close to you will also experience misfortune.

Through repeated simulations, Chen Xuan discovered that this was not the world of cultivation he yearned for. From top to bottom, it was simply a hell that devours people without spitting out their bones...

[Xuanhuan, Simulator, Plot-Driven, Ruthless MC]

Relying on the simulator, I discovered:

The dantian of righteous sect disciples hides man-eating insects.

After transmigrating, Su Ming bound a cultivation simulator.

He thought he had drawn the overpowered "Dragon-AoTian" script.

That is, until he succeeded in Foundation Establishment for the first time—

"Your consciousness fell into slumber.

You died! The end."

In the tenth simulation, the demonic cult's saintess suddenly grabbed me by the neck:

“Idiot! The blood patterns in your righteous sect's Foundation Establishment pills… are insect eggs!”

By the hundredth simulation, I finally saw:

The elders of the prestigious sects kneeling before the mother nest of sinister insects,

And the forbidden grounds of the demonic path suppressing an ancient monument used to slay these bugs.

When the entire cultivation world believed I had fallen into the demonic path—

I wielded a divine artifact obtained from the simulation

and split open the dantian of everyone, revealing the truth.

In this world teeming with psychic powers and mutations, Guts, an ordinary human, is transformed into a monster during a typical crisis. He gains the ability to freely manipulate himself and uses this power to enhance his physical body, joining an organization of human ability users.

But he didn't tell humanity where the boundaries of his "freedom," "manipulation," and "self" lay. He could freely control the actions of every cell, arbitrarily change the form of cells, manipulate cells outside the body, and transform and control other people's cells. This control ignored spatial limitations, transcended time, and everything transformed by him became himself…

To maximize his chances of survival, he planned to assimilate and integrate all life on Earth, but before that...

"Skeletal muscle shifted 20 degrees to the left... Hmm, not bad."

Gus nodded in satisfaction at the alien unit Unit 01 in front of him.

In the vast infinite surface, a new 『 guest 』 is ushered in.

Since the first strong man who refused to fly and chose to stay in the dust appeared, the history of the fairy civilization was able to turn a brand new page.

Step out of the world, and the countless unknown worlds follow.

The source of the fairyland, the end of the magic, the palace of the god, the whisper of the ancient god...

Thousands of worlds were born, and countless civilizations followed their own paths.

Faced with this world full of infinite possibilities, there is no hard work in awakening the land far of the special system.

He just wanted to traverse all walks of life and explore the mysteries and miracles of endless places until the heavens witnessed his footprints and growth, so that every memory was carved into the vast space-time.

Whitebeard: "My lord, I want a writing wheel, can you give me a face?"

Sasuke: "Lord of the Group, I really want the ability to shake the fruit, why don't I exchange it with Whitebeard?"

Fang Muguan looked at the attitude of the two of them quite sincerely, and operated in the backstage of the group.

"Swap!"

Then Whitebeard's writing wheel eye makes the pirate world fall into illusion!

Sasuke returns to the Hokage world and kills Itachi with the Shock Fruit!

Assassin Five-Six-Seven: "I actually want ...... too"

Holding an incense burner in his hand, he lit a stick of incense. The blue smoke was misty, and at that moment, the spiritual thoughts penetrated the sky and the earth, and all the shackles in the world disappeared into nothingness.

It is for immortals.
