"Look at its eyes!" Qin Sisi suddenly exclaimed in shock.
Ye You noticed the behavior of the Yin-Yang Beast, his mood grew heavy, knowing the battle ahead would be even more perilous. Hearing Qin Sisi's shout, he looked up and fixed his gaze on the beast's eyes.
The eye shooting out water was deep blue, crystal clear, like a radiant sapphire, faintly reflecting ripples of water within.
The eye spewing fire was fiery red, vivid and eerie, resembling a ruby forged from flames, with flickering jumps of fire dancing inside.
Qin Sisi's expression became solemn as she murmured, "So its eyes are..."
Ye You nodded and replied in a deep tone, "Water Fire Spirit Pearls."
Left is Yin, right is Yang—water as Yin, fire as Yang. Though water and fire oppose each other, Yin and Yang can unify.
This is the origin of the Yin-Yang Beast: the ultimate Yang and ultimate Yin coexisting within its body, mutually generating and opposing each other.
