Zombie Apocalypse? I have Infinite Storage Glitch!

It's a Fantasy story about a Guy surviving a Zombie apocalypse.
At the brink of global catastrophe, he unexpectedly obtains a storage space of a Tesseract cube , where any stored items receive a 100,000 times boost in effectiveness. "Your stored Thick pork has received a 100,000 times boost!" "Your stored fried chicken has received a 100,000 times boost!" "You have discovered a portion of petroleum, receiving a 100,000 times boost!" Before the apocalypse arrives, he stockpiles billions of supplies. While others suffer from hunger and fight for a single pack of instant noodles, Clark leisurely enjoys red wine and steak within the safety of his fortress.
