Because Lin Fei's soul power was unsealed, he was naturally able to hear Suwa's Soul Voice Transmission.
"Grandmaster Uncle, what is the Demonic Fingerprint you mentioned?" Lin Fei immediately asked via Soul Voice Transmission.
"Ah, you brat can finally hear my Soul Voice Transmission. This woman was injured by a supreme heritage technique of our Demon Clan. It's called the Demonic Fingerprint, and it leaves behind unremovable wounds or scars on whoever is struck by it. This means the Empress of our Demon Clan has been here! Who could it be? Is it the former Empress, or could it be Sayuan or Saqi?" Suwa replied.
