Genshin Impact: the Strongest Vampire in History

Vampires are a feared race. They are addicted to blood, thirst for dominance, wanton and despise everything, but they also have the power to dominate everything. Among them, the one known as the "True Ancestor" possesses the most powerful biological weapon - the Familiar Beast. Rumor has it that the beasts come from outside the world and have the power to disintegrate the world.
