Traveling Through Another World, My Life Is Like a Piece of Grass

When I woke up, I inexplicably came to a strange world and became a "Blood Crow" of the seventh-level bloodline, a low-class person whose life was as small as a piece of grass. The people here look half-human and half-demon. Their blood is supreme. The noble ones are killed and killed, while the humble ones live like grass. In order to survive, I pretend; in order to survive, I adapt; in order to survive, I endure. But dangers still come one after another, and survival is imminent. Because I am a humble seventh-level bloodline, I can only survive in the cracks of the strong. But why did I come to this world? Why should I be trampled on like this?
