"The bag is five copper coins each, so I'll give you 10 copper coins for a box," said Mag, paying no mind to the system's complaint.
The system paused for a moment before it said, "20!" Then, it added, "You can make 300 copper coins from selling a plate of Yangzhou fried rice. Subtract 20 copper coins for the box, and you can still make 280 copper coins off it. I will design the box like a top designer and paint the trademark like a top painter, and the materials will be environment-friendly and automatically degradable. The box can be reused many times…"
"Five," Mag retorted airily. "System, I'll bet you that he would be happy even if I just let him take the plate, and he would return it washed and dried. Remember, I don't have to use your boxes. And the profit of 300 copper coins off one plate is not much."
