As Sukuna in Invincible - Chapter 30: Reunion

There are a total of seven sins, and a revelation is made to a young man named Alex that he is destined to become a demon lord, more especially a demon lord of sin called LUST.

It's not like he can change that and because he always knew something about himself was different—not in a physical sense, well, maybe a little—and not in a mental sense—but rather because he is thrown into a demonic war that compels him to accept his new reality.

He was only aware of a difference in himself. Relating to him and the ladies who are drawn to him... Well, it was more or less like he was a magnet in front of all the girls, and all the girls were drawn to him like a metal.

Teenage earth dweller Lu Qingfeng died in a car accident and traversed to a world of cultivation.He acquired the Login Ring of “Primordial”, a massive immersive online game developed by the Earth Federation two thousand years later, and travelled across primordial worlds.

On the vast sea, Aokiji stopped a ship. After a great battle, Aokiji smiled helplessly, “Hey! Brother! Don’t waste your efforts! I am a natural-type ability! You can’t beat me of!”

Before the words were finished, a sword qi flashed across, freezing thousands of miles away, the frozen Qingzhi’s head crashed immediately, I was afraid that I ate a fake frozen fruit.

In the second half of the great route, Huang Yuan hummed incoherently, “Brother! You said you are faster than me! I’m so embarrassed!”

Before the words were finished, a figure stood on the flying sword and fled thousands of miles away in the blink of an eye, leaving behind a bewildered yellow ape fluttering in the wind.

Kaido: I am a blue dragon!

Someone: Sorry, my sword is also called Dragon Slayer!

 …

This is a sword story, but also a legendary story!

Of course, it is also a miracle that happened in One Piece.
