Review Detail of DaoistH in My Vampire System

It was good at the first 15 chapters but i got disappointed in the part where if he doesn't drink the blood of his victim he will lose 1hp every hour bit you know what the mc did? He didn't drink the blood for reason he will have to research first and went to his dorm and sleep and in his dying moment he went to the library and drink the blood of a female who is coincidentally therethus exposing that he is a vampire. See this pattern? It looks like so forced for me. Anyway it is just my take on this. Try reading maybe you will like it
