Rebirth in the Apocalypse: Build an Invincible Battleship

The apocalypse is coming, and various natural disasters that devour human life follow one after another. Gu Yanzhao struggled in the apocalypse for five years, but finally died unjustly. When he woke up, he found that he had been reborn three months before the apocalypse. After resurrecting his life, he vowed to protect his girlfriend and sister whom he failed to protect in his previous life. In order to resist natural disasters, he sold all his assets at the beginning, purchased a 10,000-ton cargo ship, and transformed the cargo ship into a super battleship with the help of the system. While other survivors couldn't even eat bark grass roots, he, his girlfriend and her sister were debating whether to eat steak or roast duck?
