I've Become a Genius Actor - Chapter 56:

In a land where ancient families are as common as the stars, the weight of millennia-old legacies brings not only honor but also the chains of rigid traditions. Here, bloodlines are the cornerstone of power, the unyielding foundation for climbing the ladder of authority.But what hope does the descendant of a mere hunter have in such a world? How can they claim a seat at the table in this grand feast of ambition and betrayal? Is it through the fragmented remnants of a cheat ability from the game For Honor, now warped and unrecognizable? A fleeting glimpse into an uncertain future? Or perhaps a stroke of intangible, invisible luck?The stage is set, the pieces are moving—will this unlikely contender rise, or will they become just another casualty of the Game of Thrones?

One day he suddenly found himself in hell.
All he had was the desire to live and a predation ability.
From the first to the ninth thousand circles of hell, he absorbed dozens, hundreds of thousands of demons.
Even the seven great dukes of hell bowed down before him.

– Why would you wish to go back? Doesn’t his highness have everything that’s in Hell?
– What do I have?

Nothing to eat, nothing to enjoy!
The only things in Hell are the barren lands and terrible demons!

“I’m going back.”

After ten thousand years he returns to Earth.

I just want to be different, no one can guess what I want to do, the more mysterious the more powerful.

But just when they're on the verge of success, they fail.Then, a mysterious man appears with an offer—a contract marriage in exchange for the information they desperately seek. Trapped with no alternative, they sign the deal.But neither expected what would happen next.-------------Kendrick and Zephany sat by the glass wall, waiting for their food when a car suddenly crashed through.

She can't be that loud, short-tempered woman!”“No! He can't be that silent, obnoxious man!”“Did I marry my secret partner in crime?” They both shuddered at the thought.
