Chen Shi was an ordinary supermarket tallyman until he was bound by something that claimed to be the "Business Development System of All Worlds". The system told him that he would open supermarkets in countless worlds and complete the sales quota. He thought it was a golden finger from the sky, until he found out that the first world he wanted to go to was the Doomsday Wasteland, and the start-up capital given to him by the system was five boxes of instant noodles that were expired three years ago.
