"Undying Flame? That's an artifact of The Immortals. Where did you get it?" The Undead Lord was stunned and looked at Tony curiously.
Tony shook his head, offering no explanation.
John frowned slightly. He suspected that The Immortals didn't give him the Undying Flame merely to intimidate the gods. It was probably also intended to break the seal on the Ancient Battlefield Ruins.
Seeing that Tony wasn't willing to say more, the Undead Lord turned to John and asked, "Before we proceed, can you help me break through to the demigod level first?"
To break through to the demigod level, one needed to kill a demigod-level or higher warrior.
With his current strength, the Undead Lord couldn't achieve that on his own, so he had no choice but to ask John for help.
"Of course. But there's no demigod-level being around. Let's just go with killing a lower-tier god instead." John recalled that he still had the bodies of two lower-tier gods in his storage.
