After Getting a Double Door, I Am Picking up Trash in the Apocalypse

Shen Fei, who was unemployed just after graduating from college, was suddenly bound to a god-level garbage-picking system. Before he could complain, the system issued a portal to him! This door actually leads to a parallel world - Blue Star! Blue Star's technological level is very high, but due to the outbreak of the zombie virus, there is a doomsday crisis! But because the disaster broke out a long time ago, the place Shen Fei went to became a safe empty city. What stood in front of Shen Fei was a jewelry store and a bank with their doors wide open! "Isn't this making a fortune!?" Shen Fei passed through the portal without hesitation and started the boring job of picking up garbage! Unclaimed gold? A car that can drive itself! Artificial intelligence appliances! Mobile phone with cutting-edge chip! When these high-tech products were moved to the earth, the entire network was shocked!
