There is a saying 'a man should understand that he doesn't protect his partner because their weak but because they are important.'
It seemed Rui Fei had fully grasped the meaning of this statement as he pushed Ji Yao behind him protecting him from his father. If it weren't that he wasn't strong enough in the past he would have killed Emperor Rui ages ago. The last time they fought he passed out due to years of having that poison circulating in his aetherial veins.
Now that he had fully awakened with a handle on his true form he was ready to finish his father off and protect his lover. Ji Yao grasped Rui Fei's elbow before pulling him beside him.
