Xiao Pang brought a sum of money to Shanghai Book City to buy books. The first one I bought was "Ci Hai", and half of the money I took was used, which was more than 3 yuan; the second book was "English-Chinese Dictionary", and half of the money I used was more than 3 yuan; the third book was bought. It was "Up and Down Five Thousand Years", and I spent half of the remaining money, which was more than 3 yuan; the fourth book I bought was "Journey to the West", which was more than 3 yuan after using half of the remaining money; "Love Story", half of the remaining money was used and 3 yuan less; the sixth book was "Story Club", which still used half of the remaining money and was more than 3 yuan. At this time, there was still 4 yuan left in the money he brought. So, how much did he pay for (English-Chinese dictionary)?
