After Tang Yuan died, he traveled through time and became a black cat, and was picked up by a kind-hearted classmate. He had already made the psychological preparation to cherish his second life and live as an ordinary pet cat. But he didn't expect that his classmates were not simple humans? He's not just a simple black cat either? Sure enough, since he can travel through time, there should be unscientific existences like ghosts and gods in the world! There is still hope for his human (cat) life! An ordinary little story about monsters and monsters that happened in modern times XD
