With regards to Spirit Emblems, they were not foreign to Lin Dong. Back when he was participating in the Hundred Empire War, Su Ruo had obtained such an item before. A couple of days earlier, Ling Qingzhu had also obtained a Spirit Emblem at the bottom of the Supreme Purity Celestial Pond.
Despite Lin Dong’s usual calmness, he still greatly coveted this thing. A Spirit Emblem could only be formed when an extremely powerful expert died. Gathered within the Spirit Emblem, was the vast amount of energy that belonged to the powerful expert when he was alive. In other words, it could be considered as an extremely unique natural treasure. However, this treasure used humans as its most basic ingredient.
