Five years ago, his older brother mysteriously vanished after defeating a hidden boss in the game World of the Immortal King . While the rest of the family gave up the search, he remained convinced that his brother’s disappearance is connected to the game somehow. For five years, he relentlessly challenged the same boss again and again. On his 17,860th attempt, he finally defeated the stage - and was immediately invited to cross over into the game world by a mysterious guide. There, he learns that his only chance to bring his brother back is by completing the Immortal King’s Trial. Willing to risk everything to reach his goal, he soon discovers that the so-called trial is nothing more than a deceptive scheme - a trap from which no one has ever escaped.
