C697 Mantis and cicada

Deep within polar ice pond, Han Yan was standing in front of a stone altar, with a simple bronze mirror on the stone table.

He had obtained this copper mirror from Huo Li's storage bag. As long as he laid down a spell in one place, he would be able to display everything that happened in a radius of three kilometers on the mirror. If it was only that, Han Yan would not use the treasure so easily
