After signing in for fifty years, I became the leader of the vampire clan

Fang Qingyan traveled to a foreign land of swords and magic, with hundreds of races fighting and ups and downs in the chaotic world. Unfortunately, he became a vampire, and even more unfortunately, he became the weakest and most humble last generation of blood clan.Unexpectedly, he awakened the sign-in system, and as long as he signed in, he could get amazing rewards:Sign in at Count Castain's castle to get [Count-level blood clan essence x1];Sign in at the blood clan's ancestral city of Lahmia to get the artifact [Protection of the Ancestor Lilith];Sign in the coffin of Lord Duke Dracula to get the superpower [Mind Reading];...Fang Qingyan kept a low profile in the ancestral land, and made up his mind not to come out until he cultivated the ancestral true body and ascended to the throne of God!Until one day fifty years later, the orc army of the Kingdom of Azeroth crossed the Draenor Mountains and entered the blood clan's ancestral land!Seeing that the vampires were about to be exterminated, Fang Qingyan's strength no longer allowed him to keep a low profile.
