Alone on a Global Island, My Sign-In System Is Ridiculously OP

In a single night, Blue Star fell apart, and all of humanity was exiled to an endless ocean. Each person had only a tiny four-square-meter island to struggle for survival.

Like billions of other desperate people, Ling Fan faced the ultimate trials of scorching sun, thirst, hunger, and raging waves.

But when he bound himself to a daily sign-in System and received rewards beyond his era, the course of his fate quietly changed. From his first foundation stone and first blueprint to his first mysterious cultivation technique, sign-in rewards paved an extraordinary road from a meager survivor to a lord of the deep sea. He expanded his island, unlocked ecosystems, built wonders, and fought off natural disasters and giant beasts. As regions merged and factions clashed, he competed for global supremacy and uncovered a shocking conspiracy behind it all. In this brutal sea, with his outrageously powerful sign-in System, Ling Fan would forge an undying legend and knock on the gates of godhood amid towering waves!
