When the apocalypse struck, my brother Leo didn't hesitate to choose the offshore sanctuary.
In our past life, faced with a choice between a powerful inland warlord commanding a massive army and a leader clinging to a solitary island, Leo snatched up the first option.
But when a zombie horde overran the mainland and defenses collapsed, he fled to my island for refuge.
Jealous of how well I was surviving the end of the world, he and our parents knocked me unconscious in the dead of night and threw me into the ocean to drown.
Now that I've been reborn, Leo immediately took our parents to the maritime base, leaving the "dangerous" mainland to me.
He thinks the ocean is a natural barrier that guarantees his safety, that he can sit back and relax while the world burns.
But there's one thing he doesn't know.
Zombies aren't just static, mindless walking dead—they evolve.
And when they do, that offshore sanctuary will become a floating hell with no way out.
