Sighing deeply, as Snow carry the fainted young man on his arms, before sitting down on the ground.
He was tired alright, and this energy he was slowly getting just by touching the person on his arm, was a refreshing experience, it was just a bit regrettable that he was unable to drink this person's blood at this moment on.
Not only was the restriction the problem, but it was not that easy for Snow to just easily use his fang, it was after all a thousand years of obstinate and stubbornness from not drinking someone else's blood.
Specially when Zou Yi has never really used his fang, yes you got that right, Zou Yi has never used his fang to a person.
Even to the person that he was able to drink blood in the past, was only given to him to drink in a glass cup.
So when Snow finally use his fangs, it has to be in a special circumstances and when it was completely sure that it was his fated blood partner of his choice.
