Charles was somewhat surprised and exclaimed, "You can talk?"
The woman's voice shrieked sharply, "I am a Level Eighteen Transcendent being."
Charles nodded slightly. A Level Eighteen Transcendent being was probably equivalent to the spirits in the folklore of the Eastern Great Nation whom after becoming sentient for two or three hundred years, indeed, having some intelligence was not surprising.
After some thought, Charles said, "I could also not kill, as long as your entire clan submits."
Clearing the Underground Labyrinth could mean slaughtering every monster inside or turning them into Labyrinth Guardians.
Having gained the Labyrinth Power of Agmillar, with nine Maze Runes, Charles could transform them into Labyrinth Guardians without needing the labyrinth itself. If he really could secure a group of Labyrinth Guardians, it was indeed much better than slaughtering.
