From this enlightening conversation, Ji Yao felt like he had been slapped across the face. The slap was so hard that he felt his head throbbing from all the pain. This was a side effect of having being stuffed with too much information at the same time.

Secondly, he had found out that the one person he could actually have any sort of physical contact with was Rui Fei and the likelihood of him finding someone else he could have this sort of interaction with was next to zero.
