Apocalypse: A Trillion in Supplies from the Start, and the Goddesses Beg Me to Take Them In

From the start, I got a passageway that let me travel freely between the present day and the apocalypse. What’s most valuable in the apocalypse? Gold? Black technology? No! It’s a bite to eat! A can of cola that costs two yuan in the present day can be traded for a stunning, ice-cold bodyguard with incredible combat skills in the apocalypse! A pack of compressed biscuits that costs ten yuan in the present day can get you a high-precision laser rifle from the future! Antibiotics worth a hundred yuan in the present day can be traded for blueprints for black technology a hundred years ahead of Earth!
