"The Undying Demon Blood can perfectly complement your demon heart. It can activate the demon heart within you, allowing you to transform temporarily and gain immense power. However, this power will corrode your mind, making you unable to distinguish friend from foe.

The Undying Demon Blood, also an Earth Fiend Realm treasure, is the essence blood of the Undying Demon Clan, containing abundant power that can be used as a consumable for the demon heart's operation!"
