The global blood moon is coming, the vampire virus breaks out, and humans become the food of the vampires. On the day of doomsday, Cao Yan, an ordinary college student, activated the bloodline of the ancestor of the ancient blood clan hidden in his body - the [Blood Nest] system. While others are struggling to survive in despair, he can transform any building into an absolutely safe blood nest stronghold, and can also transform the vampires he kills into loyal blood servant warriors.
However, selfish relatives heard the news and forced him to hand over control of the safe house in the name of family affection. When they discovered that Cao Yan had incredible abilities, they intensified their efforts and even colluded with outside vampire forces in an attempt to seize his ancestor's bloodline.
The simple and kind-hearted Cao Yan tolerated time and time again, but what he got in exchange was extreme betrayal. When he was pushed into a tide of corpses by his relatives on the night of the blood moon, the blood of his sleeping ancestors finally woke up. Since kindness cannot buy respect, let the world tremble under his blood nest. The end is not the end, but the beginning of a new era for the vampires.
