My Angel system - Chapter 329 Went Extinct

The leader of the thousand demons, the Demon God Chun YeoWoon. Due to an unfortunate accident, he had been sent to the distant future.

Suzumiya Kaede, a gamer, fell asleep while playing a game all night and when he woke up he found himself in another world, a fantasy world where using magic is possible! Using his knowledge of games, skills, and cheats, Kaede decides to enjoy as much of his new life in a different world through his newly-acquired magic and sword!

At first, when he learned that he was forced to go to many different routine worlds and be reborn into all kinds of cannon fodder, he was against it.

Because villains usually all only have a moment of satisfaction, the endings of cannon fodder are also frequently quite miserable.

But the man who gave him the system told him that this system not only has all types of powerful functions, but he can also break the routine lives of the cannon fodder. If he achieves this satisfactorily for each world, he can even become a god.

He’s already experienced over a thousand reincarnations, but hasn’t yet been a god. Since it sounds pretty great, why not just try it out.

From that moment on, he began the irreversible path of tyrannically oppressing people, while conveniently tearing open those white moonlights and so-called righteous people’s hypocritical masks.

His goal: wearing the villain’s role to walk other people’s righteous paths, leaving them no path to follow.

- Description from novelupdates

I had a supporting role in a modern fantasy.

The loyal dog of a villain with an angel’s name, Cheon Sa-yeon, and an unfortunate supporting character who died on his behalf, Han Yi-gyeol.

In order to escape from Cheon Sa-yeon and survive, he must use the protagonist, Ha Tae-heon.

But Ha Tae-heon, who he thought of as a lifeline, was infinitely indifferent to him. Rather, Cheon Sa-yeon showed interest.

But besides that, something strange happened.

The events that occurred in the original story had advanced, and the gate and monster levels had risen. Even the people were “different” from the original.

The original version I was trying to use was wrong.
