Seafaring: The Door-Door Fruit from the Start, and a Space Gate Is a Door Too

In the year 1500 of the Sea Circle Calendar, on an unnamed deserted island in the East Blue, Zack wakes after transmigrating. He has no System, no cheat, only a modern soul and a life-threatening predicament.

Abducted as "expendable material," he ends up in a CP9 training camp, a low-ranking child who could be eliminated at any moment. In this hell that devours people, he survives the brutal training and his companions' backstabbing through patience and cunning, fixing his gaze on the Door-Door Fruit that everyone else underestimates.

When the Door-Door Fruit awakens, spatial doors are no longer just a way to get around. Invisible doors dismantle enemy attacks layer by layer, his fists can strike vital points across space, and door after door opens onto countless worlds, including those of pirates, ninjas, and martial arts.

Clawing his way out of CP9's pile of corpses, Zack uses his worldly pragmatism to seize resources and build a covert network. He schemes across the Myriad Worlds, determined to claim the throne from which no one can escape!
