Elysian Moon was as strong as a King class could be, but her full-power attack hadn't even left a mark on the stones. The rock of that place was far sturdier than they could have imagined.
"Little red bird!" Han Sen called.
The little red bird understood what Han Sen wanted to see from it, so it shot out its phoenix fire to burn the rocks around the purple copper jian.
