The Great Shopkeeper of Wanjie: Started by Reselling Mineral Water

After Chen Jibai lost his job, he took over an old building that was about to close down. Late at night, the gray mist pushed open the door, and the apocalyptic girl exchanged the crystal core for water; the low-magic apprentice held the magic core and begged for a stable electric light; the down-and-out prince took the remnant seal of national luck for food on credit; and the cultivation master was willing to exchange spiritual stones for a set of precision measuring tools. Only then did he realize that this building was called Guixu Tower, and its door connected to all heavens and realms. Mineral water that only sells for two yuan in reality can be exchanged for crystal cores in the apocalypse; an ordinary demolition ax can kill a group of corpses; a supply promise can also be weighed by a copper scale. Starting from reselling mineral water, Chen Jibai became the best settler in the world. "Our store operates on a small budget. It can save lives. No need to negotiate credit."
