I woke up to find myself a weakling vampire with only 10 health points, and the Holy Light Knight Order was right outside to purify me! In my despair, the 【Proficiency System】activated—so long as I live, everything is grindable! To survive, I did anything! While other vampires were hunting maidens, I was slaughtering a hundred thousand rats in the sewer, my 【Bite】skill maxed out, awakening the talent 【Life Drain】! Holy Light burns painfully? I treated myself like the Monkey King's flesh and braved the Holy Light, my 【Holy Light Resistance】maxed out, awakening the talent 【Holy Light Affinity MAX】, and directly took a Holy Light bath in the church! They thought I was an elegant noble, but what I was actually thinking was, "This sword strike will probably only take 0.001% of my health—too risky, I must kill him instantly!" They called me the "Nighttime Scourge" because I targeted only the most heinous scoundrels, after all, the proficiency points from "Sinful Blood" were simply too generous! Years later, the Abyssal Demon God descended, and the gods fell. In the despair of the entire world, I brushed off the dust from my tailcoat and looked at my blood bar that had grown to an uncountable length. "You... can break my defense?"
