"The shopkeeper's purchase price was a hundred and three Oudi, which is to say that for every power card, he could get five Oudi profit. The shopkeeper purchased twenty-five one-star power cards from him every day. That is to say that he could get a hundred twenty-five Oudi in income every day. But there was a precondition." Yu Long's expression turned serious, "The precondition was that he not have one failed card. If he were to have a single failure, then his income would fizzle out, and if he were to fail with two cards, he would take a loss of seventy one Oudi every day. That showed the stunning success-rate he had making cards. What I admire the most is that he maintained such a life for four years."
Qing Qing's quiet eyes could help showing the admiration she felt.
