My 50-Year Sign-In System Made Me a Vampire God

Reborn as the lowest bloodline vampire, a mere servant, Fang Qingyan faced a life of endless humiliation in a brutal world where bloodline was everything. His salvation: a miraculous Sign-In System. For fifty years, he quietly accumulated untold power, signing in at ancient sites, gaining legendary bloodline upgrades, forbidden techniques, and artifacts. Outwardly, he remained a humble pariah. But when an overwhelming orc horde storms the ancestral lands, threatening annihilation, Fang Qingyan's façade crumbles. The world is about to discover its weakest vampire is actually its greatest weapon. Will his long-hidden, 'forbidden' power save his clan, or mark him as an even greater threat in their eyes?
