He accidentally transmigrates into the world of My Date with a Vampire, where he is bitten by the zombie king, General, and transforms into a second-generation green-eyed vampire.
In this desperate situation, he awakens a sacrificial altar that trades anything for anything, allowing him to sacrifice living beings in exchange for power and supplies.
Determined never to drink human blood, he survives through the power of sacrifice, hunts down vengeful ghosts, and protects the people amid the chaos.
He encounters Ma Dan'na, fights deadly battles against century-old ghosts, campaigns in Fengyang, bathes Jinling in blood, and ultimately faces his nemesis, Yamamoto Kazuo, embarking on an unorthodox path as a vampire in a chaotic age.
