傅小蛙收回那几十颗珠子，多多少少，他还是要有一些东西想要换，比如术士水晶，那些东西他是看着直流口水，那些院士一捏碎，能力就嗖嗖地往上涨，更让他流水口的是一些法宝，不过法宝来说，他的珠子还差得远拉。
“大叔，你们这些术士水晶咋换的？”
“术士水晶？”老者转头一望，望到架子上摆放的术士水晶。他噢地一声道：“一级的十珠一个，如果不是去历练，基本上用不到，太浪费也太奢侈了这东西！”
“给俺来几颗吧，俺最近有点太辛苦，需要这东西来补一补！”傅小蛙摸索着交上珠子。
“这东西用一回就没拉！”
“但是没这东西，我怕再下去就顶不住拉！”傅小蛙道。
“那随的你吧，我来看看，给你换三颗，要什么的。有增加速度。增强力量，增加身体强度，还有一些里面蕴有冰火电气元的，还有……”
傅小蛙左望右望。精打细算收取三颗。以对付下午的院士小组。
