During an internal Navy hearing, the top brass conducted a serious inquiry into Rogers Daren, the so-called “scum of the Marines” and Admiral of the North Blue.“You’ve had improper relations with royal princesses and noble ladies from multiple North Blue kingdoms?”“I call it showing care for the people.”Marines High Command: …“How do you explain the absurdly high salaries of the North Blue Marines under your command?”“Well, with what the HQ pays, how else do you expect them to risk their lives?”Marines High Command: (ーー`)“Why is the North Blue fleet equipped with technology from Germa?”“That’s just military-civilian cooperation. Germa 66 was moved by my sense of justice.”Marines High Command: (○_○)“And how do you explain the unusual deaths of a Celestial Dragon in the North Blue?”Daren sighed.“A maritime accident… truly unfortunate. I personally express my deepest condolences.”Marines High Command: (._.?)And so begins the story of a rebellious, unorthodox Marine.

The labyrinth that swallowed humanity. Four choices were given to them.

Easy Mode, where anyone can survive. Normal Mode, where only those who fight survive. Hard Mode, where only 1% can survive. And the Solo Mode, where only one person survived.

The strongest returnee of humanity, Kang Taesan, was an Easy Mode player.

He heard countless times,

“What if you had chosen the Hard Mode, or even the Normal Mode?”

Regretting his cowardly choice while dying amidst destruction, he gets another chance to choose.

“This time, I won’t make the wrong choice.”

The strongest Easy Mode player has returned.
