I Can Order Takeout in My Space

The protagonist Lin Bei is an ordinary takeaway rider. One day, the "Ten Thousand Realms Takeout Space" was accidentally awakened - you can take orders, deliver food, and get paid between different planes. But he discovered that the first connected plane turned out to be the apocalypse that was about to break out in three days. So he started a saucy operation: using end-of-the-world materials (gold, jewelry, rare metals) to cash out in the real world, and then using real-world money to hoard urgently needed materials for the end-of-the-world (food, medicine, weapons), and then "delivering" them to survivors of the end of the world through the takeout system. Both sides are his customers, making money from both sides, and getting stronger at the same time.
