Zhang Dabeard never fights for more than three months at a time, but he has been out for half a year now. The last time he heard from him was a strange map he sent to his son Zhang Xiaojie not long after he set off. The approximate location of the map was a place in Hebei Province, and then there were some strange symbols. The only thing Zhang Xiaojie could understand was the circled arrow symbol on the map and the remark: Seventy-Two Mysterious Tombs.
