However, as the party asking for the divorce, she couldn't tangle her limbs around his body and moan his name—— so, Song Yan suppressed that particular urge though her Yin energy was objecting wildly. It was circling Fu Yu Sheng like a predator and once in a while a small wisp of her Yin energy would shoot out of the black cloud of miasma and like a dog that was tentatively licking a new brand of dog food, would entangle with Fu Yu Sheng's Yang energy. But not for long just thirty or so seconds.
Song Yan watched her Yin energy's poor performance and had an urge to slap herself. What were they? Volcanoes that prematurely erupted? If her Yin energy was such a simp for Fu Yu Sheng's Yang energy then it might as well dance the tango with it a little more! What was this poor performance, good thing she was born as a woman, what if she was born as a man and her performance was just the same as her Yin energy.
Look at Fu Yu Sheng and his Yang energy—— totally unshakable.
