On the distant Yuyin Star, there lives a group of humans. They are greedy, selfish and attack the Vampire Clan who hope for peace all the year round. However, humans did not settle down. In the Star Language Room, a group of Yu Yinxing was born, and the abominable humans tricked them into signing a blood contract: a group of Eternal Life in the Star Language Room helped the humans who were cruelly sucked by the Vampires to resurrect with full blood!
500 Years later, humans and vampires have achieved their goals, but the Vampires still do whatever they want with humans, while the Astrology Room group abides by their duties.
