I was on my way home with my friend when suddenly, I spotted a catgirl cosplayer who made my heart skip a beat.But something felt off—I couldn’t recall seeing her in any anime, manga, or games I had ever come across.

Without thinking, I rushed to save her. In the end, both of us were hit by the truck.Now, I find myself reincarnated in another world—in the body of the very catgirl I had seen.But... who is this girl?How is she related to the dungeons that keep popping up in this new world?

- Description from novelbuddy

This world is not only as the public knows it; there is an underworld that ordinary people don't encounter.Government agents handle troubles in the shadows, while corporate assassins privately deal with issues.Assassins, mercenaries, arms dealers, and spies exist, along with a dark web that ties this world together, and tycoons who attempt to control everything with money.Gao Yi entered the underworld, unbeatable in close combat, carving out his own domain.But there are guns in this world. Beyond seven steps (close combats), guns are faster.Within seven steps, guns are both accurate and quick.Only within three steps does Gao Yi's punch become faster.Unable to beat them, he chose to join them, aiming to rule them all.To rule everything, become the king of killers in the eyes of mercenaries, the king of spies in the eyes of assassins, the king of killers in the eyes of spies, and the king of intelligence in the eyes of arms dealers.Until he is crowned king by the entire underworld, Gao Yi is the ultimate firepower.

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.
