It wasn't surprising that Amber couldn't hold on. She succumbed to these sensations feeling the most at ease with herself. 

Even normally calm Cain was having challenges just not pushing down Amber, following his instinctive desires. He could only barely hold on because he had a higher cultivated mental state. 

And under this blissful state, Cain and Amber's Soul's Core massively stirred.

Under Amber's chest, a faint blue light shimmered. And under Cain's chest, a soft green light glowed to existence. 

These lights didn't look ordinary at all. On the contrary, they looked borderline magical, breathtaking even as if they were straight from a spiritual source.

Anybody gazing upon it would feel lost, feeling like they were peering into an otherworldly scenery. 

This wasn't an all-powerful aura like Qi or mysteriously mystical like Spirit energy. But it was very enlightening like one can see into themselves from these lights.
