Traveling to another world, Lu Ming inherited a card grocery store that was about to close down.
In this world, everyone relies on summoning card creatures to fight, and card makers are extremely noble. But for an ordinary card, an apprenticeship lasts three to five days, and the rejection rate is frighteningly high, so the card price remains high all year round.
Until he discovered his own card-making slot - he put in the spiritual sand, and the card slot started to run on its own, producing black cards overnight, and the quality was even higher than that of his peers.
Others make cards to see what happens, while he makes cards to turn on the money printing press.
Regular military supplies cut off? He packed it. Is the black market black card under strict investigation? His card couldn't find the craftsman's seal. Will the city lord's card merchants and guilds join forces to lower prices? He turned around and spread his goods towards the three cities.
The city is besieged by a swarm of ants, and card dealers all over the street have exhausted their inventory and are waiting to die. His shop ships out goods overnight, getting as much as they want.
Starting from a small street in Gray Port, it has developed into a commercial road connecting the north and south, and a black card selling in three countries.
Many years later, someone asked about the history of his family. Lu Ming pointed to the wall in the shop covered with black cards:
"I said it on the first day I opened the store - no credit will be given to children and adults."
