Apocalypse: Before the Cataclysm, I Went on a Crazy Free Shopping Spree

Ye Bai is reborn seven days before the apocalypse breaks out and accidentally activates the Apocalypse Survival System, getting a shelter from the start. To protect his wife, daughter, and parents, he pours all his savings into frantically stockpiling supplies. To his delight, he also unlocks a Red Alert Construction Yard and the AllSpark, assembles a SEAL squad and a Grizzly tank army, and activates Transformer mech units. With zombie viruses and extreme disasters about to run rampant, he vows to use his preparations and formidable forces to protect his family in the apocalypse.
