Gamers of the Underworld - Chapter 463 - Declaration of War

He is high above, the mysterious and terrible King of the Wild. With one glance, he can see people’s romances. He hates women to the extreme, but at his first glance of her, he dotes on her and spoils her.
She is a humble transmigrator, a miracle doctor who doesn’t care for the many handsome men around her. She only wants to become strong, to be worthy of that god-like man. But when she’s finally sure of her feelings, she finds out she’s already been married for years…
……
When wronged：
She uses strength to hit the big handsome iceberg-like man in front of her eyes. “People say that I’m not good enough for you, but it is you who is an old cow eating tender grass!”
A man seizes the main point and laughs like an evildoer. “This husband has to eat the grass to confirm if it is tender or not!” He puts out the red candle……
……
The world says：
The barbarian king has no heart and has no passion.
A pregnant woman very miserably thinks,” If he has no passion, then who is responsible for this big belly?”

- Description from Novelupdates

The paramount existences among daemons are known as ‘Great Sages’.

A young man leaves the mountain village and wanders the world, entering the legends step by step, becoming a part of mythology itself.

Aiden Nightshade wakes up in a dark, unfamiliar forest with no memories of who he is or how he got there. The air is thick with danger, and monstrous creatures lurk in the shadows, watching him. Before he can even move, a glowing panel appears in front of him.[Welcome to the Ultimate Bond System.]A cold, synthetic female voice echoes in his mind. It tells him to tame the beasts, bond with them, and grow stronger together. But this system isn’t normal. When Aiden forms a bond with a beast, it doesn’t just become his companion—it transforms into a powerful humanoid woman, one who still has the instincts and memories of the creature she once was. They aren’t just allies. They feel his pain, share his power, and their devotion to him is absolute.As Aiden explores this strange world, he quickly realizes something—no one else can do what he does. Other tamers can control beasts, but they can’t make them evolve like he can. They do have a system but nothing like his.With his growing army of beast-women by his side, Aiden will carve his own path, breaking the rules of this world. And when he discovers that the deepest bonds unlock unimaginable strength, he understands one thing—this isn’t just about surviving.It’s about rising above everything. It’s about domination.In a world ruled by beasts, only one man will stand at the top.

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.
