Arriving in a fantasy Otherworld, Gauss obtains an Adventurer's Handbook that grows stronger the more monsters he slays and collects. Gauss originally thought he was embarking on a classic adventure to defeat the Giant Dragon, kill the Devil, and save the kingdom.

Intelligence +1, Strength +1, Constitution +1.”“The title 'Goblin Slayer' has upgraded to 'Goblin Expert'. You are an expert on goblins; few know better than you how to kill them.”“...”“The title 'Goblin Expert' has upgraded to 'Goblin Star Destruction'.”

At the beginning of the game, there is a small broken boat, and the whole family lives on the boat, which is leaking from wind and rain.

Huo Xi didn’t panic at all, rowed the small broken boat vigorously and started to make a fortune. If you don’t pay attention, you will become a rich man in the south of the Yangtze River.

It’s time to return to Beijing to take revenge and regain your identity. Take mine and return it! Eat mine and spit it out!

A black-bellied person: It’s lonely alone, why don’t you take me with you?

Huo Xixing’s eyes widened: Hurry up and hand over Xie Jin and leave! Don’t delay my sacking.

A black-bellied person: I won’t leave. How dare you play tricks on the grace of saving your life? Since then, you should promise each other with your body, be like a cow or a horse, and let yourself be driven.

Huo Xi: Huh? Set sacks together?

A black belly: go!

When a terminally ill young man awakens in the world of his favorite childhood game, he realizes he isn’t the protagonist, the destined hero, or even a major side character. Instead, he has become an extra—a disowned noble barely clinging to relevance in a world where strength determines everything. Worse, his fate in the game was to die an early, meaningless death.Armed with only his knowledge of the game’s storyline and a common system that tracks his stats and skills, he is determined to survive. But mere survival isn’t enough. He remembers a hidden easter egg from a long-forgotten anime collaboration: the Mangekyō Sharingan—a power limited by game mechanics but unrestricted in reality.With Kamui as his trump card, he walks the fine line between fate and freedom, seizing power from the shadows while avoiding suspicion. As the protagonist and his allies battle against demons and unravel the game’s grand destiny, he secretly builds his own strength—manipulating events, mastering forgotten arts, and even forging ties with villainous factions.Will he remain a footnote in history, or will he carve his own legend in a world that was never meant to be his?
