Navigator: I have a double six-story house

In a world where humanity has been forced to participate in the "Age of Exploration," Su Qing emerges as one of the newest captains, lacking the exceptional talent of his peers and without the support of parents to aid him in his pioneering endeavors. His sister's words of caution - "Brother, don't go for the full difficulty level; you're all I have" - weigh heavily on his mind as he embarks on his journey. Su Qing chooses a path that defies conventional wisdom, dragging his best friend into the treacherous "hellish difficulty" dungeon. With a mysterious double-six-room house as his only advantage, Su Qing must navigate the uncharted territories of this unforgiving world, driven by the hope of survival and the love for his sister.
