"That's impressive." Feifei nodded, immediately understanding the benefits of a Spiritual Mark.
"That's not all." Old Peun smirked as he continued, "A Spiritual Mark also acts as a reservoir of Spiritual Energy. It can store enough Spiritual Energy to activate it once. So, this means we carry it with us a trump card that can save us or change the tide of battles."
"A Spiritual Mark only has one ability each. And from what I have collected, a person can only possess one Spiritual Mark," Old Peun said solemnly. "After all, once obtained, a Spiritual Mark becomes imprinted on your soul. It can neither be inherited nor transferred. Plus, it would be carried with you even when your soul enters the reincarnation cycle. That's why they have a tremendous value."
