Stealing Lucien's powers is exactly what Tyrion is thinking about right now. Mira was probably the most talented Naga ever due to her royal bloodline, and yet, not even in the peak of the Immortal Realm was she as impressive as Lucien.
But the Naga King is blinded by greed as he can't see what trouble he's going to get himself into when trying to mess with Lucien and Lust.
"So..." He smiles and points his trident at Lucien. "To be my daughter's husband, you will need to try harder."
Kamala feels disgusted and anger as she hears those words. It's evident that Tyrion only cares about his own power, so that worried father performance fools no one.
But Lucien seems to want to play that game and smiles back at him. "As you wish."
*Whoosh*
Then he advances towards the Naga King and attacks with the naginata again. The golden glow of his eyes matches the glow of the weapon, and Tyrion feels both fear and instinctive respect for Lucien.
