Apocalyptic floods sweep across the globe, and civilization collapses. Lin Mo is reborn from a sea of corpses twenty years in the future, returning to one month before the disaster.
Burning with overwhelming hatred and regret, he swears to turn everything around. The "Abyssal Realm Heart," a spatial ability he awakens by chance, becomes his only source of support.
A lone wolf races against time, staking his future to frantically stockpile trillions' worth of supplies. He heads far inland, builds an apocalyptic fortress, and settles the scores from his past life.
The floods arrive right on schedule. He pilots an ark and saves someone crucial from the raging tide of despair, but also lets a wolf into the fold, exposing the coordinates of his island.
His plan to look out for himself is utterly shattered, forcing him to go from lone wolf to leader. He recruits allies and battles powerful foes, building a force on a lone boat amid the waters. He also makes contact with the remnants of the state, the "Reconstruction Committee," and glimpses the even more turbulent undercurrents beneath the apocalypse.
Yet they gradually discover that behind the natural disaster lurks a group of fanatics known as the "World Purification Society," along with a plot to destroy the world...
Can Lin Mo use the Abyssal Realm Heart to unite all forces, break through the depths of the apocalypse, and preserve humanity's last spark of civilization?
This is an epic journey of survival, redemption, and civilization.
