The world ended in water. In a single night, the seas swallowed the land and humanity was left drifting. Beck Zivan spent his first life as a security guard doing the unsung work protecting people, building rafts from nothing, keeping strangers alive. His reward? When the raft got too crowded, the people he’d saved threw him overboard. He drowned knowing their faces. Now, he comes back. This time, a Savior System takes root in him. Every life he rescues upgrades his vessel and grows his power. He begins preparing earlier, building smarter, choosing who he trusts more carefully. Gratitude will be returned. So will betrayal.
