My henchman, drunk, accidentally revealed he was a reincarnated individual, claiming that the apocalypse would arrive in nine days and he would kill me to seize all my wealth.
I laughed.
I'd been a pirate king for ten years; what storms hadn't I weathered?
I not only emptied his treasure chest that he considered his for the taking overnight, but also used his money to buy up all the survival supplies in the city.
When the apocalypse truly arrived, he could only kneel on the zombie-infested shore, watching helplessly as I sailed towards the absolutely safe island paradise.

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.
