Leon frowned at the serious look on Mordred's face, a trace of doubt appearing on his own.

Mordred curled his lips into a feral grin, revealing the youthful tiger teeth beneath them.

Between brows strikingly similar to Leon's, his sharpness was fully bared, brimming with killing intent like a beast poised to attack at any moment.

"Looking across the entire Earth, from ancient times to the present, I'm the only one who has ever witnessed what you're truly capable of!"

Seeing Leon's confusion, Mordred said sharply, "Father, I know your martial skill is formidable. Ordinary methods pose no threat to you!"
